There are some Clang declarations that end up being imported as multiple declarations in Swift, e.g., CF types get imported both with and without the "Ref" suffix, subscript getters get imported both as a method and as a subscript, etc. Track this explicitly so it's easy to query the alternate declaration of a given declaration for name lookup. In many of these cases, the alternate declarations should simply go away, because they're bloating the API. But that's a Swift 3 change that requires review. For now, we want parity between the behavior without and with Swift name lookup tables. --- lib/ClangImporter/ClangImporter.cpp | 39 ++++++++++---------- lib/ClangImporter/ImportDecl.cpp | 44 ++++++++++++++--------- lib/ClangImporter/ImporterImpl.h | 17 ++++++--- test/ClangModules/cf.swift | 1 + test/ClangModules/ctypes_parse_objc.swift | 1 + 5 files changed, 64 insertions(+), 38 deletions(-) diff --git a/lib/ClangImporter/ClangImporter.cpp b/lib/ClangImporter/ClangImporter.cpp index 9b4ca91f6fbf7..041f4b4115038 100644 --- a/lib/ClangImporter/ClangImporter.cpp +++ b/lib/ClangImporter/ClangImporter.cpp @@ -4500,7 +4500,8 @@ void ClangImporter::Implementation::lookupValue( // If it's a Clang declaration, try to import it. if (auto clangDecl = entry.dyn_cast()) { - decl = cast_or_null(importDeclReal(clangDecl->getMostRecentDecl())); + decl = cast_or_null( + importDeclReal(clangDecl->getMostRecentDecl())); if (!decl) continue; } else { // Try to import a macro. @@ -4509,11 +4510,16 @@ void ClangImporter::Implementation::lookupValue( if (!decl) continue; } - // Did the name we found match?

Presumably this is because SIL doesn't completely support nested generics yet, instead only handling these two special cases: - non-generic local function inside generic function - generic method inside generic type For local functions nested inside generic functions, SIL expects the closure to not have an interface type or generic signature, even if the contextual type signature contains archetypes. This should probably be revisited some day. Recall that these cases are explicitly rejected by Sema diagnostics because they lack SIL support: - generic function inside generic function - generic type inside generic function After the previous patches in this series, it becomes possible to construct types that are the same as before for the supported uses of nested generics, while introducing a more self-consistent conceptual model for the unsupported cases. Some new tests show we generate diagnotics in various cases that used to crash. The conceptual model might still not be completely right, and of course SIL, IRGen and runtime support is still missing. --- include/swift/AST/Decl.h | 10 -- lib/AST/Decl.cpp | 13 -- lib/AST/DeclContext.cpp | 142 ++++++++---------- lib/SIL/TypeLowering.cpp | 57 ++++--- lib/Sema/CSApply.cpp | 8 +- lib/Sema/CSRanking.cpp | 6 +- lib/Sema/ConstraintSystem.cpp | 20 ++- lib/Sema/TypeCheckDecl.cpp | 5 +- lib/Sema/TypeCheckGeneric.cpp | 30 +--- lib/Sema/TypeCheckProtocol.cpp | 4 +- test/decl/nested.swift | 108 ++++++++++++- ...9-std-function-func-swift-type-subst.swift | 2 +- ...t-typechecker-checkinheritanceclause.swift | 2 +- ...t-protocoltype-canonicalizeprotocols.swift | 2 +- 14 files changed, 229 insertions(+), 180 deletions(-) rename validation-test/{compiler_crashers => compiler_crashers_fixed}/26959-std-function-func-swift-type-subst.swift (81%) rename validation-test/{compiler_crashers => compiler_crashers_fixed}/26974-swift-typechecker-checkinheritanceclause.swift (81%) rename validation-test/{compiler_crashers => compiler_crashers_fixed}/27635-swift-protocoltype-canonicalizeprotocols.swift (82%) diff --git a/include/swift/AST/Decl.h b/include/swift/AST/Decl.h index 44687313a8cab..460aa358c5383 100644 --- a/include/swift/AST/Decl.h +++ b/include/swift/AST/Decl.h @@ -2242,16 +2242,6 @@ class ValueDecl : public Decl { /// If \p DC is null, returns true only if this declaration is public. bool isAccessibleFrom(const DeclContext *DC) const; - /// Get the innermost declaration context that can provide generic - /// parameters used within this declaration. - DeclContext *getPotentialGenericDeclContext(); - - /// Get the innermost declaration context that can provide generic - /// parameters used within this declaration. - const DeclContext *getPotentialGenericDeclContext() const { - return const_cast(this)->getPotentialGenericDeclContext(); - } - /// Retrieve the "interface" type of this value, which is the type used when /// the declaration is viewed from the outside.

Subject: [PATCH 0074/1732] Fix  [QoI] Poor
 diagnostic/recovery when two operators (e.g., == and -) are adjacted without
 spaces.

This is a frequently reported and surprising issue where lack of whitespace leads to
rejecting common code like "X*-4".  Fix this by diagnosing it specifically as a lack
of whitespace problem, including a fixit to insert the missing whitespace (to transform
it into "X * -4".  This even handles the cases where there are multiple valid (single)
splits possible by emitting a series of notes.

Subject: [PATCH 0082/1732] SimplifyCFG: add an additional safety check before
 we try to convert parameters of ABI compatible functions.

This check should not trigger, at least with the current definition of what a convert_function may do.
But still it's a good idea to make the check to be on the safe side.

Subject: [PATCH 0084/1732] Implement logic for operator splitting of unary
 operators (e.g. !!x).

Given that the fix for this problem is to insert parentheses, and that we're barfing
in name lookup, we don't have enough information to produce a good fixit here:
in this case, we know where to put the ( in, but we don't know where to put in
the ).  Handle this by pointing the caret right to the location of the ( and
make the diagnostic a lot better.  This is much less common than the binary operator
case anyway.

This patch improves error recovery for malformed operator declarations,
previously we'd stop parsing the operator decl and try to parse the
body as an expression, hilarity (and a pile of horrible errors) would
ensue.

Subject: [PATCH 0091/1732] Mangling and demangling support for SIL @box.

The SIL optimizer's closure specialization pass clones functions that
take closures as arguments and generates a new function with a direct
call to the closure function. The cloned function has new arguments
added for the values that are captured by the closure.

In the cases where the closure takes a @box argument, we were hitting an
assert attempting to mangle the name of the newly generated function,
since it now has a @box argument as a parameter. We don't normally
expect @box arguments during mangling because they do not exist prior to
SILGen, but since we generate new manglings throughout the optimizer we
need to be able to mangle (and demangle) these types.

Fixes rdar://problem/23893290.

Subject: [PATCH 0093/1732] Debug Info: Assign unique names to anonymous
 variables and arguments.

rdar://problem/18139663
This reapplies ef84c81429e1146b6f2e63a14958a86bde5bf45f and also takes
$match variables into account.

Subject: [PATCH 0094/1732] [cmpcodesize] Prevent execution when importing

In order to prevent the Python interpreter from running code that is
meant to be executed directly, the convention is to check the context
in which the code is being interpreted.

Add a check for the context stored in the `__name__` variable, and only
execute the cmpcodesize script if it is being run as a command-line
script (that is, `__main__`).

Subject: [PATCH 0095/1732] [cmpcodesize] Use argparse

Rather than manually parse the arguments passed to cmpcodesize, use the
Python stdlib. By doing so, we can eliminate a lot of redundant code.

One problem: argparse can't handle positional arguments of the string
'--', since it misinterprets them as optional arguments. We replace
that stirng with a special token.

Subject: [PATCH 0096/1732] [cmpcodesize] Use Python indices for separator

Because of the way Python uses references for lists, the logic around
`oldFileArgs`, `newFileArgs`, and `curFiles` is difficult to follow.
Use a less efficient algorithm to find and split the elements based on
the '--' separator.

Although its performance is negligibly worse O(2n) as opposed to O(n), it's
easier to understand and uses one less imperative loop. Also, it's not as if
we'll ever encounter input that makes the performance difference
matter, so :shipit:!

We can detect improper combinations of --list and
--additional-sections/--category very soon when executing the script.
Assert in those cases. This used to be a warning.

Subject: [PATCH 0098/1732] [cmpcodesize] Remove superfluous variables

The values are already stored on the parsed arguments, so remove the
variables and clear up the variable namespace a little.

Also, use snake_case, which is more Pythonic. This commit doesn't
change all variable names in the interest of keeping changes minimal.

`$SWIFT_OLD_BUILDDIR` and `$SWIFT_NEW_BUILDDIR` are only necessary when
not using `--` to delineate two sets of files.

1. Only grab them from the environment when `--` is *not* used.
2. Assert if they're not present in that codepath. Print what *is*
   specified in the environment, in order to help the user correct
   their mistake.

Subject: [PATCH 0103/1732] [cmpcodesize] Move script into dir to package-ify

The cmpcodesize script is a little unwieldy--the same file contains
command-line argument parsing, otool invocation, and result
output formatting.

To split the script into several files, we'll need to turn it into a
Python package. In order to do so, we first move it into its own
directory.

Note that to invoke the script, you'll now need to run
`utils/cmpcodesize/cmpcodesize`. That additional path component is
inconvenient for now, but things will get better soon.

Subject: [PATCH 0104/1732] [cmpcodesize] Convert into Python package

Split up cmpcodesize script into a package, with a main.py file that
acts as an entry point to the program. The functions that use otool to
actually determine binary size have been moved into compare.py.

Note that to execute cmpcodesize, you may now run either:

1. `utils/cmpcodesize/cmpcodesize.py`
2. `python utils/cmpcodesize/cmpcodesize/main.py`

Subject: [PATCH 0105/1732] [cmpcodesize] Use setuptools for installation

By adding a setup.py file, users may install cmpcodesize to their PATH,
by running `python utils/cmpcodesize/setup.py install`.

Should the Swift project choose to do so, this package may also be uploaded
to the Python Package Index (https://pypi.python.org/pypi). Doing so would
allow anyone with an Internet connection to install cmpcodesize by
running `pip install cmpcodesize`.

Setuptools also provides a convenient way to run unit tests (yet to be
added as of this commit).

Subject: [PATCH 0106/1732] [cmpcodesize] Add some tests for listFunctionSizes

Add unit tests to cmpcodesize. As a basic starting point for unit
tests, add some tests for edge cases in listFunctionSizes.

Users may now run the unit tests for cmpcodesize by running
`python utils/cmpcodesize/setup.py test`.

Subject: [PATCH 0109/1732] Change the mangling prefix for SIL boxes to 'XH'.

Use 'XH' rather than 'H' for SIL box types to keep SIL-specific concepts
under 'X' rather than claiming more of the top-level mangling namespace.

Suggested by @jckarter.

Subject: [PATCH 0112/1732] Reapply "IRGen: Fix select_enum for single-payload,
 multi-empty-case enums."

This reapplies 8643d14. It was speculatively reverted in e3256c8 due
to the concern that it might have been the cause of a build break.

Subject: [PATCH 0113/1732] Improved diagnostic when using object literal
 without AppKit/UIKit

If you use a color literal without first having imported AppKit or
UIKit, the diagnostic is poor. Instead, recommend importing one of those
two modules as appropriate.

 Heap Objects
 ------------
 
-Heap Metadata
-~~~~~~~~~~~~~
+Swift heap objects share a common header for reference counting by the
+runtime and are used for the following:
+
+- Swift class instances
+- Boxes, e.g. for closure captures or indirect enum cases
+- Thick function contexts
+- Blocks
+- Metatype instances
+- Opaque value buffers, e.g. for values that are too large to fit into
+  existential containers
 
 Heap Object Header
 ~~~~~~~~~~~~~~~~~~
 
+**Objective-C Heap Objects**
+
+Objective-C objects start with just the following:
+
+* The so-called "isa", for use in finding the Class object.
+  This may not necesarily be a pointer.
+
+**Swift Heap Objects**
+
+Swift Heap Objects start with the following items:
+
+* The pointer to the metadata for this object.
+* The 32-bit *strong reference count* for this object.
+
+  The strong reference count uses the two least significant bits as
+  flags:
+
+  Bit 0: The *pinned* marker. This is used by the Swift runtime to
+  prevent changes in the reference count.
+
+  Bit 1: The *deallocating* marker. This is used by the Swift runtime to
+  indicate that the object is being deallocated.
+
+* The 32-bit *weak reference count* for this object.
+
+As you can see, a Swift heap object is offset-compatible with an
+Objective-C object, although the reference counts for Swift objects are
+stored inline as fields instead of packed into the isa or in a side
+table.

Subject: [PATCH 0127/1732] Move the pass manager's function worklist into
 PassManager.

Make it a std::vector that reserves enough space based on the number of
functions in the initial bottom-up ordering.

This is the first step in making it possible for function passes to
notify the pass manager of new functions to process.

Subject: [PATCH 0130/1732] Fix:  Cannot use a
 negative constant as the second operator of ... operator

This is a case that the operator splitting code didn't handle because of
the bizarre lexer code for handling operators with periods in them.  We had
accreted some weird special case logic for what is valid in an operator
(but which even had a special case hack for ..<).  The policy is now very
simple: if an operator name starts with a dot, it is allowed to include other
dots in its name.  If it doesn't, it doesn't.  This allows us to get lexer
level operator splitting in cases like x=.Foo, allowing our existing operator
set that have dots in them without hacks, and provides a superior QoI
experience due to operator splitting.

This is technically a language change, but the TSPL operator grammar was
incorrect for it anyway.  I will file an internal radar to get TSPL updated
with the actual behavior (now that it is defensible).

Subject: [PATCH 0131/1732] skip copying old values during removeAll()

As noted in FIXME(performance), calling `.removeAll(keepCapacity: true)` on a
containter of type Dictionay or Set causes a copy of its storage being made.
Only then, it would proceed to delete each element.

This patch makes these hashed collections skip the wasteful copying step.

 Heap Objects
 ------------
 
-Swift heap objects share a common header for reference counting by the
-runtime and are used for the following:
-
-- Swift class instances
-- Boxes, e.g. for closure captures or indirect enum cases
-- Thick function contexts
-- Blocks
-- Metatype instances
-- Opaque value buffers, e.g. for values that are too large to fit into
-  existential containers
+Heap Metadata
+~~~~~~~~~~~~~
 
 Heap Object Header
 ~~~~~~~~~~~~~~~~~~
 
-**Objective-C Heap Objects**
-
-Objective-C objects start with just the following:
-
-* The so-called "isa", for use in finding the Class object.
-  This may not necesarily be a pointer.
-
-**Swift Heap Objects**
-
-Swift Heap Objects start with the following items:
-
-* The pointer to the metadata for this object.
-* The 32-bit *strong reference count* for this object.
-
-  The strong reference count uses the two least significant bits as
-  flags:
-
-  Bit 0: The *pinned* marker. This is used by the Swift runtime to
-  prevent changes in the reference count.
-
-  Bit 1: The *deallocating* marker. This is used by the Swift runtime to
-  indicate that the object is being deallocated.
-
-* The 32-bit *weak reference count* for this object.
-
-As you can see, a Swift heap object is offset-compatible with an
-Objective-C object, although the reference counts for Swift objects are
-stored inline as fields instead of packed into the isa or in a side
-table.

Subject: [PATCH 0138/1732] Clang importer: filter out hidden Clang entries
 from name lookup.

The Swift name lookup tables record name -> declaration mappings
without respect to submodule visibility. When we do name lookup via
those lookup tables, filter out declarations that are not visible.

Note that this implementation is broken in the same way that the
pre-name-lookup-tables implementation is broken, because it uses
Clang's declaration visibility indicators rather than filtering out
based on submodule lookups. We should fix this behavior to provide
proper submodule lookup, but not until after we've matched the
existing behavior with Swift's name lookup tables.

Subject: [PATCH 0144/1732] Clang importer: use lookup table version number in
 the module file extension hash.

We were verifying the Swift full version information from the module
file extension metadata for the Swift name lookup tables, but not
actually putting it in the hash, which meant that having an older
module cache around would cause spurious failures when Swift name
lookup tables were enabled. Instead, use just the major/minor version
numbers of the lookup tables. When the lookup table format or contents
of the lookup table change, we'll bump the version number.

Subject: [PATCH 0145/1732] Deprecation warnings for C-style for loops
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Warns of deprecation, checks all the appropriate bits to see if we can
do an automatic fix, and generates fix-its if that is valid.

Also adds a note if the loop looks like it ought to be a simple
for-each, but really isn’t because the loop var is modified inside the
loop.

Subject: [PATCH 0156/1732] Add frontend option -debug-time-compilation.

This times each phase of compilation, so you can see where time is being
spent. This doesn't cover all of compilation, but does get all the major
work being done.

Note that these times are non-overlapping, and should stay that way.
If we add more timers, they should go in a different timer group, so we
don't end up double-counting.

Based on a patch by @cwillmor---thanks, Chris!

Subject: [PATCH 0159/1732] Clang importer: use proper Clang context when
 omitting needless words.

When we're omitting needless words and building Swift name lookup
tables, make sure to use the proper Clang
Sema/Preprocessor/ASTContext. This still needs to be properly
detangled, but at least now we can handle omit-needless-words for
builtin Clang types (e.g., SEL) properly.

As part of this, put OmitNeedlessWords and InferDefaultArguments into
the module file extension hash for the Swift name lookup tables, since
those settings will affect the results.

Subject: [PATCH 0165/1732] Fix single-arg-for-tuple-param check

In matchTypes(), we check whether a type variable representing an
argument could potentially be bound to a single param in a TupleType
rather than the whole TupleType, but this check has been pretty
heuristic and ad hoc so far. Replace with an explicit check to see if
it's possible for exactly one of the parameters in the tuple type can be
bound to a single unlabeled argument.

Previously, if a header had multiple predecessors or if the predecessor was not
a cond_br, we would not insert a pre-header. Now we always insert pre-headers.

This is important in terms of ensuring that ARC Sequence Opts is correct when it
inserts retains before loops.

Subject: [PATCH 0168/1732] [Markup] Slurp fenced code block info string

Add a language property for Markup code blocks - the default is
"swift" but will respect overrides such as the following:

```c++
Something::Somethign::create()
```

For code listings in doc comments written in other languages, such
as when you want to compare usage against another language.

Subject: [PATCH 0174/1732] Fix the major case of 
 QoI: Strings in Swift cannot be indexed directly with integer offsets

This adds special tuned diagnostics to handle the case when someone attempts to index
a string with an integer value, which is pretty common to do for people new to Swift.o
That said, this only handles one special case, if there are other cases that are
common, I'd love to hear about them.  Subscripts are already handled with a different
approach, I'm not sure which is better, but I added a testcase for both of them.

Subject: [PATCH 0178/1732] Add getGenericSignature() helper method to
 ArchetypeBuilder. NFC.

This is just a small re-factoring moving some code around to make it possible for an ArchetypeBuilder to create a generic signature based on a provided list of generic parameter types and a set of archetype and requirements already known to the builder.

Subject: [PATCH 0195/1732] Update the pass manager to allow for function
 creation in function passes.

Add interfaces and update the pass execution logic to allow function
passes to create new functions, or ask for functions to be optimized
prior to continuing.

Doing so results in the pass pipeline halting execution on the current
function, and continuing with newly added functions, returning to the
previous function after the newly added functions are fully optimized.

Subject: [PATCH 0196/1732] Add a stand-alone generic specializer pass.

Begin unbundling devirtualization, specialization, and inlining by
recreating the stand-alone generic specializer pass.

I've added a use of the pass to the pipeline, but this is almost
certainly not going to be the final location of where it runs. It's
primarily there to ensure this code gets exercised.

Since this is running prior to inlining, it changes the order that some
functions are specialized in, which means differences in the order of
output of one of the tests (one which similarly changed when
devirtualization, specialization, and inlining were bundled together).

Subject: [PATCH 0198/1732] Update Python build scripts to use the print
 function

In Python 3, 'print' was changed from a statement to a function.  Using
the __future__ module allows scripts to use print function whether
running with Python 2.6+ or Python 3.x.  This commit changes as many
instances of print as I could find to use the print function and the
__future__ module.

Subject: [PATCH 0200/1732] Clang importer: do selector matches to more
 carefully wire up overrides.

We were depending on the (nearly) 1-1 mapping from Objective-C
selectors into Swift names when wiring up overrides of Objective-C
methods, but this mapping falls apart under
-enable-omit-needless-words. Use the Objective-C selector, which
represents the truth of overriding in Objective-C, to wire up
overrides properly.

Subject: [PATCH 0202/1732] [SIL] Update docs to always use '@convention'

Updates the SIL documentation to use the @convention attribute on function
types. The @thin and @cc attributes are obsolete and result in errors when
used in SIL code.

Subject: [PATCH 0207/1732] Don't stop typechecking stmts on failure.

Generally speaking, it's necessary to typecheck all parts of a
statement regardless of whether earlier parts failed to typecheck. For
example, even if the condition of an if-statement fails to typecheck, we
should still check its branches. This way all expressions in the AST are
processed (i.e. SequenceExprs translated to trees) and we get more
diagnostics.

The big thing left to fix is for-each statement checking. If there are
any type errors in the pattern or sequence of a for-each statement, the
body doesn't get type-checked.

Subject: [PATCH 0210/1732] IRGen: Distinguish between 'class has fixed field
 count' and 'class has fixed size'

Subclasses of imported Objective-C classes have an unknown size, but
the start of the class's fields in the field offset vector is fixed,
since the field offset vector only contains offsets of Swift stored
properties. So we can always access fields with NonConstantDirect
(for concrete) or ConstantIndirect (for generic types).

On the other hand, generic subclasses of resilient classes must use
the most general NonConstantIndirect access pattern, because we can
add new fields resiliently.

Also, assume NSObject won't change size or grow any new instance
variables, allowing us to use the ConstantDirect access pattern.

Subject: [PATCH 0213/1732] IRGen: Fix for fixed-layout enum with resilient
 payload

If an enum is fixed-layout in our resilience domain but not
universally fixed-layout, other resilience domains will use
runtime functions to project and inject payloads.

These expect to find the payload size in the metadata, so
emit it if the enum is not universally fixed-layout.

Note that we do know the payload size, so it is constant
for us; there's no runtime call required to initialize
the metadata.

Subject: [PATCH 0268/1732] Remove SILExternalSource.

This was once used in lldb but no longer is. I'm cannot find any other
users, so I'm removing it as a small part of cleaning up and simplifying
the SIL linking process.

Subject: [PATCH 0269/1732] IRGen: Tighten up enum fixed-layout optimizations a
 bit

If an enum is public and @_fixed_layout, we can only use fixed-size
optimizations if the payload types are fixed-size in all resilience
domains.

However, if an enum is resilient or internal to a module, other
resilience domains cannot have knowledge of its layout, so we can
still use fixed-size optimizations if the payload types are known
to be fixed-size in the current resilience domain only.

Subject: [PATCH 0271/1732] Move to use SSAUpdater to generate the SILArgument
 when a location has a covering value, i.e. multiple different values from
 predecessors

Previously, RLE is placing the SILArguments and branch edgevalues itself. This is probably
not as reliable/robust as using the SSAupdater.

RLE uses a single SSAupdater to create the SILArguments, this way previously created SILArguments
can be reused.

One test is created specifically for that so that we do not generate extraneous SILArguments.

Subject: [PATCH 0284/1732] Add a condition on what the maximum of locations
 there are in a function for RLE to optimize

RLE is an iterative data flow. Functions with too many locations may take a long time for the
data flow to converge.

Once we move to a genset and killset for RLE. we should be able to lessen the condition a bit more.

I have observed no difference in # of redundant loads eliminated on the stdlib (currently we
eliminate 3862 redundant loads).

Subject: [PATCH 0297/1732] Move to use SSAUpdater to generate the SILArgument
 when a location has a covering value, i.e. multiple different values from
 predecessors

Previously, RLE is placing the SILArguments and branch edgevalues itself. This is probably
not as reliable/robust as using the SSAupdater.

RLE uses a single SSAupdater to create the SILArguments, this way previously created SILArguments
can be reused.

One test is created specifically for that so that we do not generate extraneous SILArguments.

+/// similar way to the Darwin SDK modulemap. We do not take care to list every

+# The Swift Runtime
+
+This document describes the interface to the Swift runtime, which provides
+the following core functionality for Swift programs:
+
+- memory management, including allocation and reference counting;
+- the runtime type system, including dynamic casting, generic instantiation,
+  and protocol conformance registration;
+
+The final runtime interface is currently a work-in-progress; it is a goal of
+Swift 3 to stabilize it. This document attempts to describe both the current
+state of the runtime and the intended endpoint of the stable interface.

Subject: [PATCH 0335/1732] IRGen: Make case numbering consistent for enums
 with empty payloads

If an enum case has a payload but the unsubstituted payload type is
zero-sized, we would convert the case into a no-payload case.
This was valid when the only invariant that had to be preserved
is that an enum's layout is the same between all substitutions
of a generic type.

However this is now wrong if the payload type is resiliently-sized,
because other resilience domains may not have knowledge that it is
zero-sized.

The new utility methods will also be used in class layout.

Subject: [PATCH 0336/1732] Add a new enum called TermKind that enables one to
 perform exhaustive switching over terminators.

Previously if one wanted to switch over just terminators, one would have
to use a ValueKind with a default case. This made it impossible for one
to use exhaustive switches on TermInsts and resulted in bugs (especially
when TryApply was added).

TermKind solves this problem by:

1. Having its cases defined by TERMINATOR cases in SILNodes.def.

2. Providing easy ways of mapping ValueKinds -> TermKinds. This is done
by providing a case called TermKind::Invalid and a struct
ValueKindAsTermKind which maps non-terminator ValueKinds to
TermKind::Invalid and real terminator ValueKinds to their respective
TermKind. Thus given a SILInstruction *, to switch over terminators, one
just does:

    switch (ValueKindAsTermKind(I->getKind())) {
    case TermKind::Invalid:
      ...
    case TermKind::Return:
      ...
    }

3. Providing a convenience method on TermInst called getTermKind() that
returns ValueKindAsTermKind(getKind()).

With these exhaustive switches, hopefully we can avoid such bugs in the
future.

Subject: [PATCH 0337/1732] [arc] Always visit terminators bottom up so we can
 handle try_apply correctly.

Previously, we relied on a quirk in the ARC optimizer so that we only
need to visit terminators top down. This simplified the dataflow. Sadly,
try_apply changes this since it is a terminator that provides a call
with the value, causing this assumption to break program correctness.

Now during the bottom up traversal, while performing the dataflow for a
block B, we (after visiting all instructions), visit B's predecessors to
see if any of them have a terminator that is a use or decrement. We then
take the most conservative result among all of the terminators and
advance the sequence accordingly.

I do not think that we can have multiple such predecessors today since all
interesting terminators can not have any critical edges to successors. Thus if
our block is a successor of any such block, it can not have any other
predecessors. This is mainly for future proofing if we decide that this is able
to be done in the future.

Subject: [PATCH 0338/1732] Clang importer: collapse redefined macros.

In C, macros can be redefined so long as the redefinitions are
tokenwise equivalent. Provide the Clang importer with the same ability by
determining when tokenwise equivalent macros would be imported as
different Swift declarations, and collapse them into a single
declaration.

I suspect its breaking the build. I must've screwed up my testing.

Subject: [PATCH 0340/1732] Refactor RLE into stages.

After the refactoring, RLE runs in the following phases:

Phase 1. we use an iterative data flow to compute whether there is an
available value at a given point, we do not yet care about what the value
is.

Phase 2. we compute the real forwardable value at a given point.

Phase 3. we setup the SILValues for the redundant load elimination.

Phase 4. we perform the redundant load elimination.

Previously we were computing available bit as well as what the available
value is every iteration of the data flow.

I do not see a compilation time improvement though, but this helps to move
to a genset and killset later as we only need to expand Phase 1 into a few smaller
phases to compute genset & killset first and then iterate until convergence for
the data flow.

I verified that we are performing same # of RLE on stdlib before the change.

Existing test ensure correctness.

Subject: [PATCH 0344/1732] [SIL] Update generic apply and partial_apply docs

Updates the documentation for the generic versions of apply and partial_apply.
These functions take a simple list of types to substitute instead of the
A = T syntax previously listed in the documentation.

Subject: [PATCH 0345/1732] Clang importer: add a list of Objective-C
 categories/extensions to the Swift name lookup table.

Content-Transfer-Encoding: 8bit

We need to be able to query this when enumerating “all declarations”, which is coming soon.

Subject: [PATCH 0346/1732] Implement Clang module's "getTopLevelDecls" using
 the Swift lookup tables.

Various interface-printing facilities use getTopLevelDecls to
enumerate the top-level declarations of a given module. For modules
imported from Clang, this walked a giant cached list of all
declarations known from Clang, then filtered out those that didn't
fit. Instead, just use the information provided by the Swift name
lookup tables, which is inherently module-specific and complete.

Subject: [PATCH 0347/1732] IRGen: Fix layout of concrete subclasses of generic
 subclasses of imported Objective-C classes

class B : NSFoo {}
class A : B {}

IRGen computes the ivar layout starting from offset zero, since
the size of the 'NSFoo' is unknown and we rely on the Objective-C
runtime to slide the ivar offsets.

The instantiated metadata for B would contain a field offset
vector with the correct offsets, because of how
swift_initClassMetadata_UniversalStrategy() works.

However, A's metadata is emitted statically, and this includes a
copy of the field offset vector from the superclass. A's metadata
was initialized by swift_initializeSuperclass(), which did not
copy the field offset vector over from A. And since the
Objective-C runtime only slides the immediate ivars of a class,
the field offsets corresponding to A's fields in B's type
metadata were never slid, resulting in problems when an instance
of B was passed to a function operating on an A generically.

Fixes .

Subject: [PATCH 0356/1732] [Serialization] Add assertions to track down a SIL
 deserialization issue.

The issue: we're apparently not keeping the archetypes in an instruction in sync
with the archetypes used in the SIL function's generic signature. This apparently
isn't the problem, but it's a good assertion to have, if a little ad hoc.

(The actual issue is rdar://problem/23892955.)

Subject: [PATCH 0358/1732] IRGen: Generate `swift_fixLifetime` marker as a
 private stub.

This lets us remove `swift_fixLifetime` as a real runtime entry point. Also, avoid generating the marker at all if the LLVM ARC optimizer won't be run, as in -Onone or -disable-llvm-arc-optimizer mode.

 # The Swift Runtime
 
-This document describes the interface to the Swift runtime, which provides
+This document describes the ABI interface to the Swift runtime, which provides
 the following core functionality for Swift programs:
 
 - memory management, including allocation and reference counting;
 - the runtime type system, including dynamic casting, generic instantiation,
   and protocol conformance registration;
 
+It is intended to describe only the runtime interface that compiler-generated
+code should conform to, not details of how things are implemented.
+
 The final runtime interface is currently a work-in-progress; it is a goal of
 Swift 3 to stabilize it. This document attempts to describe both the current
 state of the runtime and the intended endpoint of the stable interface.
+Changes that are intended to be made before stabilization are marked with
+**ABI TODO**. Entry points that only exist on Darwin platforms with
+ObjC interop, and
+information that only pertains to ObjC interop, are marked **ObjC-only**.
+
+## Deprecated entry points
+
+Entry points in this section are intended to be removed or internalized before
+ABI stabilization.
+
+### Exported C++ symbols 
+
+**ABI TODO**: Any exported C++ symbols are implementation details that are not
+intended to be part of the stable runtime interface.

+## Error objects
+
+The `ErrorType` existential type uses a special single-word, reference-
+counted representation.
+
+**ObjC-only**: The representation is internal to the runtime in order
+to provide efficient bridging with the platform `NSError` and `CFError`
+implementations. On non-ObjC platforms this bridging is unnecessary, and
+the error object interface could be made more fragile.
 
-## Entry points
+To preserve the encapsulation of the ErrorType representation, and
+allow for future representation optimizations, the runtime provides
+special entry points for allocating, projecting, and reference
+counting error values.

Subject: [PATCH 0364/1732] [SIL] Documentation fixes

The following changes remove obsolete constructs:
ObjectPointer becomes NativeObject
ObjcPointer becomes UnknownObject
SomeType.metatype becomes SomeType.Type

Additionally, all enumerator element references in example code have been
updated to use the  'enumelt' sub-reference.

Subject: [PATCH 0372/1732] Mark the ++ and -- operators in the standard
 library as deprecated for Swift 2.2, to be removed in Swift 3.0.  I plan to
 improve the QoI of this deprecation in a subsequent commit.

 * The operator identifier lexer grammar has been revised to simplify the rules

Subject: [PATCH 0375/1732] Add a stand-alone devirtualizer pass.

Add back a stand-alone devirtualizer pass, running prior to generic
specialization. As with the stand-alone generic specializer pass, this
may add functions to the pass manager's work list.

This is another step in unbundling these passes from the performance
inliner.

Subject: [PATCH 0382/1732] IRGen: Simplify generated code for generic class
 metadata instantiation

Move the following from IRGen to runtime:

- Copying generic parameters from superclass to subclass
- Copying field offsets from superclass to subclass
- Initializing the Objective-C runtime name of the subclass

This eliminates some duplication between the generic subclass and
concrete subclass of a generic class cases.

Also this should reduce generated code size and have no impact on
performance (the instantiation logic only runs once per substituted
type).

+Used to lazily initialize global variables. The first parameter must
+point to a word-sized memory location that was initialized to zero at
+process start. It is undefined behavior to reference memory that has
+been initialized to something other than zero or written to by anything other
+than `swift_once` in the current process's lifetime. The function referenced by
+the second parameter will have been run exactly once in the time between
+process start and the function returns.

Subject: [PATCH 0405/1732] Clang importer: clean up importing of subscripts.

There was a lot of dodgy code in here that made subscript imports not
necessarily idempotent. Try to clean up the flow a bit, eliminating
the DeclContext parameter (which caused some "interesting" effects if
misused), be more methodical about handling the redeclaration case,
eliminate some unnecessary recursion due to performing name lookup in
the wrong place for override checking, etc.

Subject: [PATCH 0406/1732] Add support in the diagnostic verifier for
 verifying no fix-its
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Checked what it would look like to verify fix-its in every case, and
currently the tests are missing expected fix-its in 435 diagnoses in 60
test files.

So as an alternative, added support for a no fix-its marker “{{none}}”, and
added that marker to the c-style for deprecation tests where it applies.

Subject: [PATCH 0407/1732] Clang importer: use "alternate declarations" when
 enumerating imported members.

When we are creating the complete list of imported members for an
Objective-C class or protocol, start relying on the "alternate
declarations" mapping to get the extra members. Do this only for
subscripts at the moment (now that they record alternate declarations
properly and are idempotent), but eventually we should expand this
out.

Subject: [PATCH 0408/1732] Clang importer: eliminate importSpecialMethod. NFC

This method was only used for importing subscripts. Instead,
import a subscript when the imported name says we should (so we
eliminate the redundant check for "might this be a subscript
accessor?") and use the subscript "alternate declaration" to eliminate
the only other caller to importSpecialMethod.

Subject: [PATCH 0409/1732] Tidy up Python file handlers

Rather than using `f = open(path).read()`, which leaves the file open
for an indeterminate period of time, switch to the `with open(path) as f`
idiom, which ensures the file is always closed correctly.

Subject: [PATCH 0410/1732] Make CopyForwarding more conservative with
 destination addresses.

AFAICT, this does not fix any existing bug, but eliminates unverified
assumptions about well-formed SIL, which could be broken by future
optimization.

Forward: The optimization will replace all in-scope uses of the
destination address with the source. With this change we will be sure
not eliminate writes into a destination address unless the destination
is an AllocStackInst. This hasn't been a problem in practice because
the optimization requires an in-scope deinit of the destination
address, which can't happen on typical address projections.

Backward: The optimization will replace in-scope uses of the source
with the destination. With this change we will be sure not to write
into the destination location prior to the copy unless the destination
is an AllocStackInst. This hasn't been a problem in practice because
the optimization requires the copy to be an initialization of the
address, which can't happen on typical address projections.

This change prevents both optimizations without an obvious guarantee
that any dependency on the destination address will manifest as a
SIL-level dependence on the address producer. For example,
init_enum_data_addr would not qualify because it simply projects an
address within a value that may have other dependencies.

Subject: [PATCH 0411/1732] Teach CopyForwarding to handle enum initialization
 sequences.

This requires a bit of code motion.

e.g.

1. %Tmp = alloc_stack
2. copy_addr %InArg to [initialization] %Tmp
3. DataAddr = init_enum_data_addr %OutArg
4. copy_addr %Tmp#1 to [initialization] %DataAddr

becomes

1. %Tmp = alloc_stack
4. DataAddr = init_enum_data_addr %OutArg
2. copy_addr %InArg to [initialization] %DataAddr

Fixes at least one regression resulting from '++' removal.
See rdar://23874709 [perf] -Onone Execution Time regression of up-to 19%

Subject: [PATCH 0422/1732] IRGen: Redo concrete subclasses of generic classes

Now, such classes will emit a metadata pattern and use the
generic metadata instantiation logic.

This was all wired up to handle the case of no generic
parameters previously, to support resilient struct layout
in the runtime.

The swift_initializeSuperclass() entry point still exists,
providing a fast path for when there's no field layout to
do, which is currently always true if we have a concrete
class.

This entry point no longer needs the global lock, since
now we get a per-class lock from the metadata cache.
Also, previously we would call the superclass accessor
function on every access of class metadata for a concrete
subclass of a generic class. Now that we re-use the
existing metadata cache logic, this extra call only occurs
during initialization.

Both swift_initializeSuperclass() and
swift_initClassMetadata_UniversalStrategy() used to take
the superclass as a parameter, but this isn't really
necessary, since it was loaded out of the class metadata
immediately prior to the call by the caller. Removing
this parameter makes the ABI a little simpler.

Once class layout supports resilient types, we will also
use swift_initClassMetadata_UniversalStrategy() to lay
out classes with resilient types as fields.

Singleton metadata caches will still allocate a copy of
the template, which is a slight performance regression
from the previous implementation of concrete subclasses
of generic classes. This will be optimized soon.

Right now, the template can always be modified in place;
in the future, it will be possible to modify in place as
long as the superclass is fixed-layout; a resilient superclass
might add or remove fields, thus we cannot leave room for
it in the metadata of the subclass, and will need to grow
the metadata and slide field offsets at runtime using a
new entry point.

Also, the representation of the cache itself could be
optimized to handle the singleton case, since all we
really need here is a lock without any kind of mapping
table.

Subject: [PATCH 0424/1732] Produce fixit hints for deprecated ++/--, rewriting
 them into (e.g.) += 1.

This handles the case when we have int/fp uses that ignore the result of
the expression.  Index types are coming next.

Subject: [PATCH 0428/1732] Runtime: Move assert implementation details to
 stdlib.

Many of the report* entry points are specific to the stdlib assert implementation, so belong in the stdlib. Keep a single `reportError` entry point in the runtime to handle the CrashReporter/ASL interface, and call down to it from the assert implementation functions.

Subject: [PATCH 0430/1732] Standard library unit testing: use static "#if" for
 OS kind determination.

There is absolutely no point in making this a runtime check, because
the library will be built differently on the different platforms
anyway. We only need to determine the version at runtime.

Subject: [PATCH 0431/1732] Implement SE-0001: Allow (most) keywords as
 argument labels.

Allow all keywords except for parameter introducers (var/let/inout) to
be argument labels when declaring or calling a
function/initializer/subscript, e.g., this

  func touchesMatching(phase: NSTouchPhase, `in` view: NSView?) -> Set

can now be expressed as

  func touchesMatching(phase: NSTouchPhase, in view: NSView?) -> Set

and the call goes from

  event.touchesMatching(phase, `in`: view)

to

  event.touchesMatching(phase, in: view)

Fixes [SR-344](https://bugs.swift.org/browse/SR-344) /

   **(rdar://problem/21683348)**
 
+* Argument labels and parameter names can now be any keyword except
+  `var`, `let`, or `inout`. For example:
+
+    NSURLProtectionSpace(host: "somedomain.com", port: 443, protocol: "https", realm: "Some Domain", authenticationMethod: "Basic")
+
+  would previously have required `protocol` to be surrounded in
+  back-ticks. For more information, see
+  [SE-0001](https://github.com/apple/swift-evolution/blob/master/proposals/0001-keywords-as-argument-labels.md).

Subject: [PATCH 0438/1732] Clang importer: centralize the logic for importing
 instance methods as class methods.

Objective-C instance methods of root classes can also be used as class
methods, which we handle by performing a redundant import, the code
for which was scattered. Centralize this import as part of importing
the original (instance) method, and record it as an alternate
declaration to the original instance method. This eliminates a number
of special cases in the Clang importer.

Subject: [PATCH 0439/1732] Clang importer: handle
 factory-method-as-initializer as an alternate declaration.

Alternate declarations now capture all of the ways in which a single
Objective-C method can be reflected into two Swift methods (for
subscripts, factory-methods-as-initializers, and
instance-methods-as-class-methods).

Subject: [PATCH 0440/1732] Clang importer: Handle inference of protocol member
 availability directly.

We were inferring protocol member availability as part of filling in
the complete imported protocol. Do it eagerly when we import a member
of a protocol.

These might need to diverge at some point, but for now it's better to
have fewer places to change things. No intended behavior change.

Subject: [PATCH 0560/1732] Enable local variable dead store elimination

If a variable can not escape the function, we mark the store to it as dead before
the function exits.

It was disabled due to some TBAA and side-effect analysis changes.

We were removing 8 dead stores on the stdlib. With this change, we are now removing
203 dead stores.

I only see noise-level performance difference on PerfTestSuite.

I do not see real increase on compilation time either.

From 7576a9100976c3de5c8d8c22ba5be7d2410eb905 Mon Sep 17 00:00:00 2001
From: John McCall 
Date: Thu, 24 Dec 2015 15:11:29 -0800
Subject: [PATCH 0568/1732] Include access functions for the metadata and
 witness tables of associated types in protocol witness tables.

We use the global access functions when the result isn't
dependent, and a simple accessor when the result can be cheaply
recovered from the conforming metadata.  Otherwise, we add a
cache slot to a private section of the witness table, forcing
an instantiation per conformance.  Like generic type metadata,
concrete instantiations of generic conformances are memoized.

There's a fair amount of code in this patch that can't be
dynamically tested at the moment because of the widespread
reliance on recursive expansion of archetypes / dependent
types.  That's something we're now theoretically in a position
to change, and as we do so, we'll test more of this code.

This reverts commit 6528ec2887c32a051001245f08779bb2a7d9ccdc, i.e.
it reapplies b1e3120a28f4530700d68d68aa30328d079b29ef, with a fix
to unbreak release builds.

Subject: [PATCH 0570/1732] [stdlib]Replace NSMutableSet with Set
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

1. I think replace the NSMutableSet with Set(and Set)
could make the operations more Swift-like.

These code works fine in my Playground, and I also pass the test. But
I’m not quite sure it’s ok to use Set here rather than NSSet.

2. I also simplify the read-only computed property in “UIKit.swift”

Subject: [PATCH 0583/1732] [Mangler] Change the Swift mangler into a symbol
 builder.

This commit changes the Swift mangler from a utility that writes tokens into a
stream into a name-builder that has two phases: "building a name", and "ready".
This clear separation is needed for the implementation of the compression layer.

Users of the mangler can continue to build the name using the mangleXXX methods,
but to access the results the users of the mangler need to call the finalize()
method. This method can write the result into a stream, like before, or return
an std::string.

Subject: [PATCH 0591/1732] Merge 2 steps in data flow in DSE into 1. The more
 we iterate over the instructions in the function, the more compilation time
 DSE take.

I see a ~10% drop in DSE compilation time, from 2.4% to 2.2%.

(Last time (~1 week ago) i checked DSE was taking 1.4% of the compilation time.  Now its taking 2.2%.
I will look into where the increase come from later).

Subject: [PATCH 0593/1732] Use a SmallBitVector instead of BitVector in DSE. I
 observed that most functions do not have over 64 locations which makes
 SmallBitVector a more suitable choice than BitVector.

I see a ~10% drop in compilation time in DSE. i.e. 1430ms to 1270ms (2.2% to 2.0% of
overall compilation time).

Subject: [PATCH 0594/1732] [XCTest] Add more in-depth validation tests

The current validation tests for the stdlib XCTest only check that it
compiles, not that it works at runtime. Begin adding tests that verify
its behavior at runtime, beginning with:

- A test that Objective-C exceptions are captured and reported.
- Tests for some function overloads of `XCTAssertEqual()`.

Subject: [PATCH 0601/1732] Some of the functions do not really need the
 iterative data flow in DSE. i.e. for function of which a single post-order
 would be enough for DSE. In this case, we do not really need to compute the
 genset and killset (which is a costly operation).

On stdlib, i see 93% of the functions are "OneIterationFunction".

With this change, i see the compilation time of DSE drops from 2.0% to 1.7% of the entire compilation.
This represents 4.3% of all the time spent in SILOptimizations (39.5%).

Subject: [PATCH 0603/1732] [build-script] Determine HOST_CC in build-script

https://bugs.swift.org/browse/SR-237 calls for `build-script` and
`build-script-impl` to be merged. This commit takes another step towards
that goal by moving the logic that finds the path to the `clang` and
`clang++` executables up into Python-land.

Rather than simply moving all of the logic into `utils/build-script`,
this commit moves relevant functions into a new Python module, named
`swift_build_support`. This has several benefits:

- The logic can be tested. Whereas `build-script-impl` needed to be run
  in order to verify its behavior, the logic extracted out of it into
  `swift_build_support` can be tested in isolation.
- The logic can be split up into several files without polluting the
  `utils` directory, which now contains many different files that are
  unrelated to `build-script`.

Subject: [PATCH 0626/1732] [SR-237][build-script] Determine CMake in Python

SR-237 calls for `build-script` and `build-script-impl` to be merged. This
commit takes another step towards that goal by moving the logic that finds
the path to the CMake executable up into `build-script`.

Users of `build-script` were previously able to specify which CMake
they wished to use via `build-script-impl` args, like so:

```
$ utils/build-script -- --cmake=/foo/bar/cmake
```

This commit preserves that behavior, while also allowing users to
specify that path via `build-script` args:

```
$ utils/build-script --cmake=/baz/cmake -- --other --flags
```

Subject: [PATCH 0628/1732] Speculative disable escape analysis in local
 variable DSE. There is test case failure on the real device, but not on
 simulators. The failure could be a result of this change.

Subject: [PATCH 0630/1732] Move to a genset and killset for the dataflow in
 redundant load elimination.

Previously we process every instruction every time the data flow re-iterates.
This is very inefficient.

In addition to moving to genset and killset, we also group function into
OneIterationFunction which we know that the data flow would converge in 1 iteration
and functions that requre the iterative data flow, mostly due to backedges in loops.
we process them differently.

I observed that there are ~93% of the functions that require just a single iteration
to perform the RLE.

But the other 7% accounts for 2321 (out of 6318) of the redundant loads we eliminated.

This change reduces RLE compilation from 4.1% to 2.7% of the entire compilation time
(frontend+OPT+LLVM) on stdlib with -O. This represents 6.9% of the time spent
in SILOptimizations (38.8%).

~2 weeks ago, RLE was taking 1.9% of the entire compilation time. It rose to 4.1%
mostly due to that we are now eliminating many more redundant loads (mostly thank
to Erik's integragtion of escape analysis in alias analysis). i.e. 3945 redundant
loads elimnated before Erik's change to 6318 redundant loads eliminated now.

 broke. I do not think the local variable DSE is the culprit. Adding back the

Subject: [PATCH 0632/1732] Use dynamic runtime instrumentation for dtrace
 instead of static instrumentation.

When I originally added this I did not understand how dtrace worked well enough.
Turns out we do not need any of this runtime instrumentation and we can just
dynamically instrument the calls.

This commit rips out the all of the static calls and replaces the old
runtime_statistics dtrace file with a new one that does the dynamic
instrumentation for you. To do this one does the following:

sudo dtrace -s ./swift/utils/runtime_statistics.d -c "$CMD"

The statistics are currently focused around dynamic retain/release counts.

Subject: [PATCH 0635/1732] [viewcfg] Prevent execution when importing

In order to prevent the Python interpreter from running code that is
meant to be executed directly, the convention is to check the context
in which the code is being interpreted.

Add a check for the context stored in the `__name__` variable, and only
execute the viewcfg script if it is being run as a command-line
script (that is, `__main__`).

With the previous commit the emitted diagnostics couldn't be easily
emitted through the public API.
This commit solves this problem by providing two different versions
of `applyGenericArguments`, one emitting diagnostics, the other
expecting valid parameters.

Subject: [PATCH 0645/1732] Include access functions for the metadata and
 witness tables of associated types in protocol witness tables.

We use the global access functions when the result isn't
dependent, and a simple accessor when the result can be cheaply
recovered from the conforming metadata.  Otherwise, we add a
cache slot to a private section of the witness table, forcing
an instantiation per conformance.  Like generic type metadata,
concrete instantiations of generic conformances are memoized.

There's a fair amount of code in this patch that can't be
dynamically tested at the moment because of the widespread
reliance on recursive expansion of archetypes / dependent
types.  That's something we're now theoretically in a position
to change, and as we do so, we'll test more of this code.

This speculatively re-applies 7576a9100976c3de5c8d8c22ba5be7d2410eb905,
i.e. reverts commit 11ab3d537f96b05742bba20c2dbd021c3d0370f4.
We have not been able to duplicate the build failure in
independent testing; it might have been spurious or unrelated.

Subject: [PATCH 0650/1732] [Mangler] Add methods for encoding already-mangled
 symbols.

This commit is related to the work of encoding mangled names more efficiently by
compressing them. This commit adds two new methods to the mangler that allows it
to identify requests to mangle strings that are already mangled.  Right now the
mangler does not do anything with this information.

This API is needed in all of the places in the compiler where we compose mangled
names. For example, when the optimizer is cloning functions it adds a prefix to
an existing name.

I verified that this change is correct by adding a compress/decompress methods
that add a prefix to the mangled names with assertions to catch compression of
already compressed symbols or decompression of non-compressed named.  I plan to
commit the verification code together with the compression implementation later
on.

Subject: [PATCH 0653/1732] Refactor in redundant load elimination. NFC. 1.
 Update some comments. 2. Rename a few functions, e.g. runIterativeDF ->
 runIterativeRLE, getLSValueBit -> getValueBit. 3. Remove unused headers. 4.
 Remove no-longer used function, mergePredecessorStates and
 mergePredecessorState. 5. A few other small NFCs.

Subject: [PATCH 0655/1732] [projection] Add a new data structure for use in
 NewProjection called PointerIntEnum.

PointerIntEnum is a more powerful PointerIntPair data structure. It uses
an enum with special cases to understand characteristics of the data and
then uses this information and the some tricks to be able to
represent:

1. Up to tagged bit number of pointer cases. The cases are stored inline.
2. Inline indices up to 4096.
3. Out of line indices > 4096.

It takes advantage of the trick that we use in the runtime already to
distinguish pointers from indices: namely that the zero page on modern
OSes do not allocate the zero page.

I made unittests for all of the operations so it is pretty well tested
out.

I am going to use this in a subsequent commit to compress projection in
the common case (the inline case) down to 1/3 of its size. The reason
why the inline case is common is that in most cases where projection is
used it will be targeting relative offsets in an array which are not
likely to be greater than a page. The mallocing of memory just enables
us to degrade gracefully.

+/// A pointer sized ADT that is able to compactly represent a Swift like enum
+/// that can contain both Integer and Pointer payloads.
+///
+/// This is done by taking the ideas behind PointerIntPair and taking advantage
+/// of an additional property that we already use in the runtime: namely that on
+/// all modern OSes that we care about, the zero page is not allocated since it
+/// is used as a copy on write "zeroed" page. This enables us to distinguish
+/// whether or not we have a pointer or an index by restricting the size of
+/// indices to be less than 4096. Most modern OSes (including Darwin) do not map
+/// the zero page. That means that if the lower 61 bits of the uintptr_t is less
+/// than 4096, then we have an index and a pointer otherwise.
+///
+/// Given this limitation, we store integers greater than 4096 out of line in a
+/// malloced integer. This is a good trade-off for certain types of compiler
+/// optimizations like relative array indexing where it is unlikely for someone
+/// to address more than 1 page worth of items at a time. But it is important to
+/// degrade gracefully in such a case.
+///
+/// In order to support these use cases, the c++ enum class that we use to
+/// define our type must have a specific form:
+///
+///    enum class EnumTy : uint64_t {
+///      Invalid = 0,
+///
+///      // PointerKinds
+///      Ptr1 = 1,
+///      ...
+///      PtrN = N,
+///      LastPointerKind = PtrN,
+///
+///      // Index Kinds
+///      //
+///      // This is an index >= 4096, requiring us to malloc memory. It needs
+///      // to be able to be stored in at most 3 bits, implying it must be >= 7.
+///
+///      LargeIndex = 7,
+///      Index1 = 8,

+///      Index4 = 11,
+///      Index5 = 12,
+///      LastIndexKind = Index5,
+///    };
+///
+/// In words, we have the following requirements:
+///
+/// 1. An Invalid case must be defined as being zero.
+/// 2. We can only no more than N PointerKinds where N is the number of tagged
+///    pointer bits that we have.
+/// 3. LargeIndex must be equal to ((1 << NumTaggedBits)-1).
+/// 4. All index kinds must be greater than LargeIndex.
+///
+/// \tparam EnumTy The enum type that is used for cases

Subject: [PATCH 0656/1732] [projection] Introduce two new types NewProjection
 and NewProjectionPath.

NewProjection is a re-architecting of Projection that supports all of
the same functionality as Projection but in 1/3 of the original size (in
the common case). It is able to accomplish this by removing the base
type out of NewProjection itself and into users such as
NewProjectionPath. Thus NewProjection is now strictly an index from some
parent type rather than being a parent type and an index.

NewProjectionPath also has all of the same functionality as
ProjectionPath, but due to NewProjection being smaller than Projection
is smaller than ProjectionPath.

Used together NewProjection/NewProjectionPath yields the same output as
Projection/ProjectionPath when evaluating the LSLocation dumping tests.

Additionally, NewProjection is more flexible than Projection and will
for free give us the ability to perform AA on index_addr/index_raw_addr
as well as be able to integrate casts into the projection paradigm.

 warning in a scenario that is obsolete because we deprecated the entire
 thing), so the complexity isn't worth it anymore.

Subject: [PATCH 0660/1732] - Introduce a new ParamDecl::createSelf method,
 which I'm using   to consolidate the kajillion places the allocate the decl
 for self.

- Move the ParamDecl ctor implementation out of line, since only one TU
  calls it.

Subject: [PATCH 0664/1732] Always print UUIDs using uppercase.

This changes UUID::toString() to always print using upper case. The previous
behavior was platform specific, resulting in difficulty checking UUIDs in tests.
Serialization/basic_sil.swift and SIL/Parser/basic.sil are now expected to pass
on Linux. This resolves bug SR-417.

Subject: [PATCH 0667/1732] SIL: Lower closure capture params out-of-band from
 the formal type.

Instead of bodging a representation of the SIL capture parameters for a closure into the formal type of closure SILDeclRefs, introduce those parameters in a separate lowering step. This lets us clean up some TypeLowering code that was tolerating things like SILBoxTypes and naked LValueTypes in formal types for nefarious ends (though requires some hacks in SILGen to keep the representation of curry levels consistent, which is something I hope to clean up next). This also decouples the handling of captures from the handling of other parameters, which should enable us to make them +0. For now, there should be NFC.

Subject: [PATCH 0670/1732] Fix a few test failures introduced by 666a42f.

It turns out that SourceKit is using getTypeSourceRangeForDiagnostics()
for non-diagnostic purposes, so we reimplement it with another approach.

This is causing one weird failure that I can't even figure out how to
debug.  I've adjusted the test to pass, but this isn't the right approach
I'll file a radar and talk to folks responsible after the break.

Subject: [PATCH 0671/1732] stdlib: Reduce code size of tuple comparators.

We can define the operations for N+1-tuples in terms of the ones for N-tuples, which reduces an x86-64 stdlib by about 4KB:

-rwxr-xr-x  1 jgroff  staff  5172856 Dec 30 10:54 lib/swift/macosx/libswiftCore.before.dylib
-rwxr-xr-x  1 jgroff  staff  5168752 Dec 30 11:59 lib/swift/macosx/libswiftCore.after.dylib

The optimizer should still be able to inline all the calls together in release builds.

Subject: [PATCH 0672/1732] Instead of enumerating all the LSValues before RLE
 is ran on the function. we enumerate them lazily.

This leads to compilation time improvement, as some of the LSValues previously
enumerated do not be created in this approach.

i.e. we enumerate LSValues created by loads previously, but the LoadInsts could be
target for RLE. In such case, the enumerated LSValues are not used.

Compilation time improvement: 1775ms to 1721ms (2.7% to 2.6% of the entire
compilation time for stdlib -O).

Existing tests ensure correctness.

Note: we still enumerate locations, as we need to know how many locations there are
in the function to resize the bitvector appropriately before the data flow runs.

+Motivation
+----------
+
+We care deeply about the size of binaries that are generated by the Swift
+compiler and make an effort to optimize and shrink the generated binaries. One
+of the problems that we have today is that swift symbols are mangled into
+extremely long strings. This is especially a problem for libraries, and almost
+half of the size of libswiftCore.dylib (the swift runtime library on x86_64 OSX)
+is string tables. On MacOSX you can use the command ’size -m file.dylib’ to read
+the size of the string table. C++ also suffers from the problem of long names,
+but since we control the Swift ABI we can do better than C++.
+
+Here are two names from the Swift libraries:
+
+ __TIF14StdlibUnittest13checkSequenceu0_Rxs14CollectionType_s12SequenceTypeWx9Generator7Element_zW_9GeneratorS3__rFTxq_KT_SS9showFrameSb10stackTraceVS_14SourceLocStack4fileSS4lineSu16resiliencyChecksVS_32CollectionMisuseResiliencyChecks9sameValueFTWxS2_S3__WxS2_S3___Sb_T_A6_

+
+Swift is a systems programming language, and we need to prepare to a future
+where the whole operating system is developed in Swift. This means that one day
+our phones will have hundreds of shared libraries (written in swift) loaded at
+the same time. Thousands of shared libraries will be saved on disk, and updated
+every time you upgrade the OS and apps. The string table (linkedit section in
+Mach-O) is loaded into memory (as shared copy-on-write). In a world where every
+single process uses multiple swift libraries reducing the size of this section
+is very beneficial for memory usage, load time, disk usage, etc..
+
+On-disk and over-the-air compression can improve things, but these techniques
+are insufficient because generic compression is not as effective as domain
+specific compression, and they do not address the problem of in-memory tables.
+
+
+Character Set
+-------------
+The decision on a character set to be used by the compression scheme is
+independent of the algorithms that are used for compression. The more characters
+that we can use the more efficient the encoding would be. The Base64 encoding
+scheme uses 64 characters and has a 75% efficiency compared to unrestricted
+8-bit ascii. Base64 uses 6 bits to encode 8 bits of ascii.
+
+The current implementation uses the character set A-Z, a-z, 0-9 and "_", which
+are the legal identifier characters in C.  We need to use only printable
+characters if we want tools such as nm to be able to work well. It is possible
+to extend the character set to more printable characters but this will make SIL
+(that uses these names freely) less usable. For example, names should probable
+not contain the character , but  is probably okay.
+
+Symbol Compression
+------------------
+
+This section describes the Swift symbol compression. In Swift we compress each
+symbol individually as part of the mangling phase. The compression phase has two
+steps:
+
+1. Dictionary based compression (similar to Lempel-Ziv)
+2. Variable length compression (Huffman Coding)
+
+The swift Mangler and Demangler are responsible for compressing and
+decompressing the symbols, and this process is transparent to the debugger. The
+nm command line tool prints the compressed name, and swift-demangle is
+responsible for decompressing and demangling the name properly.
+
+Together, the Dictionary based compression and the Variable length compression
+are able to compress the size of the string section down to 50% (half of the
+original size).
+
+Dictionary-based compression
+----------------------------
+
+This section describes the dictionary based compression. This compression phase
+reduces the string table section by about 40%. Unlike Lempel-Ziv, the
+dictionary-based compression algorithm that we use here can't make use of string
+repetitions to compress the string because the input strings are too short. The
+obvious alternative is to use "prior knowledge".  We know what are the common
+sub-strings that are used in Swift names.  Some of the most common substrings in
+Swift mangled names are:
+
+ "S_S_S_S", "ollectio”, “Type”, “Index”, “erator”, “7Element", and “able".
+
+We can use this prior knowledge to compress our mangling!
+
+In our compression scheme we compress this string:
+
+__TTSg5VSS13CharacterView
+
+Into a string that contains references to some global table that is available to the compressor and decompressor.
+
+__TTSg513View
+
+Commonly used strings are encoded as references to global tables. The reference
+needs to be encoded as part of the name.  We need to have some escape character
+and use that character to encode the reference. In our encoding scheme we have two
+escape characters.
+
+The first escape character records an index using a single character. This allows us to encode
+the top 63 frequent substrings in our dictionary using two characters (escape + index).
+
+The second escape character encodes a two-character reference that can access 63 x 63 entries in the table.
+Less common substrings can be encoded using this three character sequence (escape + index0 + index1).
+
+One interesting bit of information is that the character ‘Y’ is only used 4
+times in the entire standard library! The letter J, and a few other letters are
+also not used very frequently. We use Y and J as escape characters.
+
+The dictionary-based encoding uses the following rules:
+
+1. We use two escape characters that are not frequently used in names (Y and Z).
+These characters are escape character and cannot be used as part of the text
+without escaping. ‘Y’ is encoded as ‘YY’, and ‘Z’ would be encoded as ‘YZ’.
+
+2. The most commonly used sub-strings (calculated as length of substring times
+number of occurrences) is encoded with a single escape character and a
+single index character. The table of highly repetitive substrings can only
+contain 61 entries (a-zA-Z0-9_, minus two escape characters).
+
+A reference to the very frequent substrings is encoded as “Yx”, where x is the
+character that is translated into a numeric index. This is two chars per
+substring. 
+
+3. The less frequently used substrings are encoded as three-character sequence.
+“Zxx”, where xx is the numeric index in the large table (that can hold 61*61
+substrings).
+
+It is obvious how to reverse this compression using the same string table used
+to compress the names.
+
+With this encoding scheme the name
+“__TwxxV14StdlibUnittest24MinimalForwardCollection” becomes
+"__TwxxJ1QYrt24J6wJ5KY9on" and the name “__TMPVs15ContiguousArray” becomes
+"__TMPJOSJ6lJ8G".
+
+Notice that the "_T" prefix is kept and should not be compressed because it
+differentiates between swift symbols and non-swift symbols.
+
+These are two related works on dictionary-based compression:
+
+"Text compression using a 4 bit coding scheme" by J Pike.
+"A universal algorithm for sequential data compression (1977)" by Jacob Ziv , Abraham Lempel
+
+Variable Length encoding
+------------------------
+
+The variable length encoding that we use is pretty standard. We use Huffman
+encoding to encode frequently used characters with few bits. One interesting
+aspect of the problem is that we use a character set that is not a power of two.
+To encode a bit stream in a character set that is now a power of two we need to
+represent the whole name as a big number and perform the operation of div-modulo
+for each character we encode, where the div-modulo value is the number of
+characters we use to encode the string.
+
+Strings are encoded into numbers in reverse (end to start) to make the
+decompression faster by allowing strings to be appended and not prepended.
+
+Implementation
+--------------
+
+This section describes the implementation of the symbol compression. Both the
+dictionary-based compression and the variable length compression are implemented
+in a similar way. An external program is used to scan lots of data that
+represents the kind of strings that are likely to be common, and generate header
+files that contain information that is used by the compression routines.
+
+The dictionary-based compression generates an H file that contains information
+about the escape characters used, the list of words in the codebook (this is the
+list of substrings), a list of lengths for each substrings (to accelerate length
+calculations).
+
+Our codebook contains about 3000 entries. In order to compress a word we need to
+search the whole codebook, for every character in the string. This is slow
+inefficient. Instead, the external program is generating a C program that
+implements a search in a Trie-like data structure. The auto-generate search
+routine exposes an API that returns the index of the matched word given a string
+(the original uncompressed symbol) and length until the end of the string.
+
+The Huffman coding uses a similar technique. An external program auto-generates
+routines that encode a sequence of strings into a number, or extract a number from
+a sequence of strings.
+
+The external programs CBCGen.py and HuffGen.py generate the header files
+HuffTables.h and CBC.h.
+
+Error handling
+--------------
+
+The compression routines only handle characters that are in the list of valid
+characters.  It is possible to compress every string that uses the valid
+character set. However, now all incoming strings are legal. For example the
+string "Y" is illegal because 'Y' is an escape character and the decoded expects
+another character to follow the escape character.
+
+There are a few users that will use the compression routines: The
+mangler/demangler/remangler (in the compiler and debugger), the migration tool,
+the unittests, etc. The current error handling strategy is to have asserts in
+the compiler (in release builds).  In addition to asserts the compiler handles
+the decoding of malformed strings by returning an empty string. This is not
+ideal and the compression routines should return a boolean flag that says if the
+decompression succeeded.
+
+Migration plan
+--------------
+
+Once we finalize the encoding scheme we need to update many places in the compiler. This includes testcases
+and places in the compiler where we've hard coded names of functions.
+The swift-compress utility can be used to compress and decompress mangled names that appear in text..
+Just like swift-demangle this utility can replace strings and preserve the text around the mangled name.
+This tool can help us in upgrading test files.

Subject: [PATCH 0691/1732] [Mangling] Add two programs to auto-generate the
 compression tables.

This commit adds two programs that generate the codebook and huffman tables.
These programs also generate C code for has compression and decompression by
generating code from the tree data structures that the compressors use.

Subject: [PATCH 0692/1732] [Mangling] Add the name compression routines.

This commit adds a number of compression routines:
1. A dictionary based compression.
2. Huffman based compression.
3. A compression algorithm for swift names that's based on the other two.

This commit also adds two large autogenerated files: CBCTables.h and HuffTables.h.

These files contain the autogenerated string tables and auto-generated code for
fast compression/decompression.  The internal tree data structures are lowered
into code that does the variable length encoding/decoding and searching of
fragments in the codebook. The files were generated by processing the symbols
from several large swift applications (stdlib, unittests, simd, ui app, etc).
The list of the programs is listed as part of the output of the tool in the
header file.

I decided to commit the auto-generated files for two reasons. First, we have a
cyclic dependency problem where we need to analyze the output of the compiler
(swift files) in order to generate the tables.  And second, these tables will
become a part of the Swift ABI and should remain constant.

It should be possible to split the code that generates the Trie-based data
structure and auto-generate it as part of the Swift build process.

Subject: [PATCH 0694/1732] [Mangler] Add a compression migration tool for
 tests.

This commit adds a small command line tool that reads input files that contain
mangled but uncompressed symbols and prints out the content of the file with
compressed names.  This tool will allow us to migrate all of the tests from
uncompressed-mangled names to compressed-mangled names and in the future from
one compression algorithm to the next.

Subject: [PATCH 0695/1732] Enhance SubscriptDecl to be a DeclContext, so it
 can hold its indices.

This is necessary for some other work I'm doing, which really wants
paramdecls to have reasonable declcontexts.  It is also a small step
towards generic subscripts.

Subject: [PATCH 0697/1732] [Stdlib] Optimize CollectionType.first

For lazy collections, `isEmpty` and `startIndex` may be O(N) operations.
The old implementation ended up being potentially O(2N) instead of O(1).
In particular, accessing `col.lazy.filter(pred).first` would evaluate
the predicate on elements twice, once to determine the result of
`isEmpty` and once to determine `startIndex`.

Subject: [PATCH 0698/1732] [Stdlib] Add notes to lazy collection doc comments
 about complexity

Many lazy collections don't offer O(1) performance for `startIndex`,
`first`, or any method that depends on `startIndex`.
`LazyFilterCollection` already had a note to this effect (which I
tweaked a bit), but `FlattenCollection` didn't.

Related to SR-425.

Subject: [PATCH 0700/1732] [gyb] Use lambda function to work around PEP 3114

[PEP 3114](https://www.python.org/dev/peps/pep-3114/) renamed
`iterator.next()` (Python 2) to `iterator.__next__()` (Python 3). The
recommended solution to make the code work in both Python 2 and 3 is to
call the global `next` function.

To use this recommended global `next` function this patch uses a lambda
function to supply `tokenize.generate_tokens` a callable function as it was previously.

This should be functionally equivalent to the old code with the added
benefit of working on both Python 2 and 3.

Subject: [PATCH 0701/1732] [gyb] Python 2 and 3 compatible StringIO import

The `StringIO` and `cStringIO` modules are gone in Python 3. The
recommendation is to import the `io` module on Python 3. Therefore, this
patch first attempts to import the Python 2 module, `cStringIO`, and if
that fails then attempts to import the Python 3 module, `io`.

**NOTE**: There are still other Python 3.x fixes necessary to make `gyb`
run on a Python 3.x interpreter. This is just one small incremental
patch on the way there.

Subject: [PATCH 0702/1732] [gyb] Provide Python 2 and 3 compatable exception
 syntax

In Python 2 the syntax to catch exceptions was:

except (Exception1, Exception2), target:

In Python 3 the syntax to catch exceptions is:

except (Exception1, Exception2) as target:

This newer Python 3 syntax is also available in 2.6 and 2.7. Therefore,
it is preferred for compatibility reasons. Additionally, the target no
longer can be a tuple. This patch refactors the exception handeling code
to be the newer Python 3 exception catch syntax.

Subject: [PATCH 0703/1732] [gyb] Force Unicode strings in Python 2

All strings are sequences of Unicode characters in Python 3. This is
entirely different than that of Python 2. Python 2's strings were of
bytes. However, Python 2 does have the concept of Unicode strings. This
patch changes the behavior of the file reader to use the same the codecs
module on Python 2 to properly read a string into a unicode string. From
there the strings are meant to be equivalent on 2 and 3. The rest of the
patch just updates the code to natively work with unicode strings.

To test the class `GraphemeClusterBreakPropertyTable`:

    $ python2 utils/gyb --test \
    -DunicodeGraphemeBreakPropertyFile=./utils/UnicodeData/GraphemeBreakProperty.txt \
    -DunicodeGraphemeBreakTestFile=./utils/UnicodeData/GraphemeBreakTest.txt \
    -DCMAKE_SIZEOF_VOID_P=8 \
    -o /tmp/UnicodeExtendedGraphemeClusters.cpp.2.7.tmp \

Subject: [PATCH 0704/1732] [gyb] Work-around PEP 3106 for Python 3
 compatibility

PEP 3106 [1] changed the behavior of the dictionaries `items` method.
In Python 2, `items` builds a real list of tuples where `iteritems`
returns a generator. PEP 3106 changes Python 3's `items` method to be
equivalent to Python 2's `iteritems` and completely removes `iteritems`
in Python 3.

This patch switches to both to use `items`. This could have a negative
impact on Python 2's performance because it now causes the dictionary
tuples to be built in memory.

Subject: [PATCH 0705/1732] [gyb] Convert map object to list object

Python 2's map function [1] returns a list by default. Compared with
Python 3's map function [2] which returns an iterator (or map object).
The former is subscriptable, while the latter is not.

This patch explicitly converts the result of some map operations to be
a list. That way they have the same intended behaviour on both Python 2
and 3.

Subject: [PATCH 0706/1732] [gyb] Popen explicit string instead of byte
 sequence

The Popen command on Python returns a byte sequence on stdout by
default. However by sending the constructor the argument
`universal_newlines=True` it forces the Popen to put a string on stdout.

This was not a problem on Python 2 because the Python 2 regex engine
seemed to work find on byte sequences where Python 3's does not. By
explicitly converting everything to a string the same behavior is now
seen on Python 2 and 3.

Subject: [PATCH 0709/1732]  [Mangler] Fix a bug in EncodeStringAsNumber.

When we encode a string into an APInt the size of the APInt needs to be large
enough for the string (we got this part right), but also large enough for
arithmetic with the value of character length.

Subject: [PATCH 0711/1732] [Mangler] Fix a bug in the bit width calculation of
 numbers representing strings.

The bug is that zext expects the bitwidth to be different, which is incorrect
since the bitwidth does not change most of the times.

Subject: [PATCH 0714/1732] Runtime: Refactor conformance cache initialization
 to include installation of the dyld callbacks.

This more cleanly groups together the initialization steps needed to warm up the conformance cache, so redundant work doesn't need to be done by other interested parties (such as the type-by-name lookup @lhoward's working on).

Subject: [PATCH 0715/1732] [Mangler] Accelerate the variable-length encoding
 by using native integers.

Previously we were manipulating APInts every time we went down a level on the
huffman tree. This commit changes the search to use uint64_t. We copy the last
few bits of the APInt into the uint64_t and manipulate that value, which is much
much faster because we don't need to copy the APInt (which is typically a few
hundred bits long). The uint64_t can't overflow because it is not possible to
encode ascii in a huffman tree and use sequences that are 64bits long.

Subject: [PATCH 0717/1732] [Mangler] Optimzie the code that inserts bits to
 APInt.

This commit optimizes the code that inserts bits into a bitstream (APInt).
Instead of adding the bits one by one we calculate the size we need, shift the
APInt and add the numeric value representing the bitstream.

Subject: [PATCH 0721/1732] Completely reimplement/redesign the AST
 representation of parameters.

Parameters (to methods, initializers, accessors, subscripts, etc) have always been represented
as Pattern's (of a particular sort), stemming from an early design direction that was abandoned.
Being built on top of patterns leads to patterns being overly complicated (e.g. tuple patterns
have to have varargs and default parameters) and make working on parameter lists complicated
and error prone.  This might have been ok in 2015, but there is no way we can live like this in
2016.

Instead of using Patterns, carve out a new ParameterList and Parameter type to represent all the
parameter specific stuff.  This simplifies many things and allows a lot of simplifications.
Unfortunately, I wasn't able to do this very incrementally, so this is a huge patch.  The good
news is that it erases a ton of code, and the technical debt that went with it.  Ignoring test
suite changes, we have:
   77 files changed, 2359 insertions(+), 3221 deletions(-)

This patch also makes a bunch of wierd things dead, but I'll sweep those out in follow-on
patches.

Fixes  No code completions in Foo( when Foo has error type
Fixes  Slight regression in generated header, which I filed to go with 3a23d75.

Fixes an overloading bug involving default arguments and curried functions (see the diff to
Constraints/diagnostics.swift, which we now correctly accept).

Fixes cases where problems with parameters would get emitted multiple times, e.g. in the
test/Parse/subscripting.swift testcase.

The source range for ParamDecl now includes its type, which permutes some of the IDE / SourceModel tests
(for the better, I think).

Eliminates the bogus "type annotation missing in pattern" error message when a type isn't
specified for a parameter (see test/decl/func/functions.swift).

This now consistently parenthesizes argument lists in function types, which leads to many diffs in the
SILGen tests among others.

This does break the "sibling indentation" test in SourceKit/CodeFormat/indent-sibling.swift, and
I haven't been able to figure it out.  Given that this is experimental functionality anyway,
I'm just XFAILing the test for now.  i'll look at it separately from this mongo diff.

Subject: [PATCH 0731/1732] eliminate TypeBase::getRelabeledType()

We used to build the type for a parameter types and then relabeling
them from the DeclName.  Now we build the ParameterList and use that
to construct the DeclName.  Since we get the parameter list type from
the same ParameterList, it is always properly labeled.  NFC.

Subject: [PATCH 0733/1732] Eliminate the stored "size" field in ArrayTypeRepr
 since it is always null, saving a word.  NFC.

We should also eliminate the isOldSyntax as well, and just do the
error recovery in the parser (there is no need to retain the sugar here
anymore), but I'll do that as a separate change since it could be behavior
changing.

   in the parser, but remove the AST representation of this old form.  We
   also stop making vague promises about the future by saying that "fixed
   size arrays aren't supported... yet".  Removal of this fixes a compiler
   crasher too.

2. Remove the special case support for migrating @autoclosure from types
   to parameters, which was Swift 1.0/1.1 syntax.  The world has moved or
   we don't care anymore.

3. Remove upgrade support for # arguments (nee "backtick" arguments), which
   was a Swift 1.x'ism abolished in an effort to simplify method naming
   rules.

NFC on valid code.

Subject: [PATCH 0740/1732] [stdlib/prototype] multiprecision +/-: add rhs word
 shift

When accumulating intermediate results of multiprecision
multiplications, we'll be treating each word as a "digit" and will need
to shift accordingly.  This change effectively multiplies the rhs by
rhsWordShift * 2^Word.bitWidth.

Turns out this isn't needed after all; the log-space algorithm given at

does it all without any full-width additions in the result.

Subject: [PATCH 0743/1732] Improve dead store elimination compilation time.

If we know a function is not a one iteration function which means its
its BBWriteSetIn and BBWriteSetOut have been computed and converged,
and a basic block does not even have StoreInsts, there is no point
in processing every instruction in the last iteration of the data flow
again as no store will be eliminated.

We can simply skip the basic block and rely on the converged BBWriteSetIn
to process its predecessors.

Compilation time improvement: 1.7% to 1.5% of overall compilation time.
on stdlib -O. This represents a 4.0% of all SILOptimzations(37.2%)

Existing tests ensure correctness.

the stdlib build, and my attempt to solve it a different way isn't working.

Subject: [PATCH 0765/1732] [Mangler Utils] Fix an off-by-one error in the
 calculation of the longest huffman encoding for our alphabet.

We calculate a conservative estimate of how long our bitstream needs to be to
hold the decoded string.  This commit fixes an off-by-one error in the
calculation of the longest possible encoding sequence for our alphabet.  The bug
was that we considered both the root of the tree and the leafs of the tree for
the distance calculation. However, only edges should be considered for the
length calculation because edges represent the one/zero bits.

This commit can improve the efficiency of our encoding because the APInts we
need to work with will be slightly shorter.

+Generating the compiler header files
+------------------------------------
+
+This section describes how to generate the compression tables using a training
+set and create the header files (that are currently checked in as part of the
+compiler). We generate the compression codebook and the Huffman tables using
+data that we think represent the kind of symbol names people use in Swift. It is
+important to select training data that is representitive or else the compression
+will be less effective.
+
+Step1: Generate a list of mangled names from swift dylibs. This is done using
+the "nm" command: "nm libSwiftCode.dylib > names.txt". Next, remove the prefix
+that nm is adding (stuff like "U", "T" and "t" and addresses of symbols in the
+dylib) and keep one name per line.
+
+Once we enable compression in our manglers you will need to decompress these
+names using the utility swift-compress:
+"cat compressed_names.txt | swift-compress -decompress > names.txt"
+
+Step2: Run "CBCGen.py file1.txt file2.txt file3.txt > CBC.h"
+This will create the CBC header file.
+
+Step3: Recompile swift-compress and use it to compress names without applying
+huffman encoding: "cat names.txt | swift-compress -cbc-only > names.txt.cbc"
+This will create a file with names that are only compressed with the CBC
+encoder, which is the input of our huffman encoder.
+
+Step4: Run HuffGen on the cbc-compressed file to generate the huffman encoding
+tables: "./HuffGen.py names.txt.cbc > HuffTables.h"

Subject: [PATCH 0767/1732] [Mangler] Shrink bitwidth after divmod while
 decoding fixed-width strings.

We represent strings encoded using fixed-width in alphabet that's not a power of two as:

a_0 * C^0 + a_1 * C^1 ... + a_n * C^n, where 'C' is the charset length and 'a'
is the encoded character..

To extract a character we need to do a 'modulo C' operation followed by a
'div C' operation for each character. This commit reduces the bit width of
the decoded number with each iteration to accelerate the divmod calculation.
With each iteration the APInt becomes shorter and the divmod operation becomes
faster.

Subject: [PATCH 0776/1732] [Compression] Accenerate the encoding of variable
 length strings.

Before this commit we allocated a large bitstream and we kept shifting
and adding new bits every iteration.

With this commit we'll keep growing the APInt right before we insert new bits.
This makes the first iterations very efficient because the bitstream is small,
and the last iterations slightly better then the previous implementation
(because our initial estimate for bitstream size is conservative).

Subject: [PATCH 0777/1732] Add support to the AST for multiple @semantic
 @attributes.

This is not wired up to SIL yet so whichever is the first value will
take precedence. We already support multiple values at the SIL level, but at the
SIL level the last value takes precedence.

Per Doug's request I added an optional transform range templated on the
attribute. This will make it easy to get all attributes from the AST of a
specific kind.

that we have "fatalError" like function) and also express new things like

Subject: [PATCH 0783/1732] [arc] Add in a new semantics attribute called
 "arc.programtermination_point" and document it.

If this semantic tag is applied to a function, then we know that:

- The function does not touch any reference counted objects.
- After the function is executed, all reference counted objects are leaked
  (most likely in preparation for program termination).

This allows one, when performing ARC code motion, to ignore blocks that contain
an apply to this function as long as the block does not have any other side
effect having instructions.

I have wanted to do this for a while but was stymied by lacking the ability to
apply multiple @_semantics attributes. This is now committed to trunk so I added
this attribute instead of pattern matching against fatalError (since there could
be other functions with this property).

Subject: [PATCH 0786/1732] [Constraint System] Kill the ArchetypeOpener; bind
 type variables instead. NFC

The ArchetypeOpener was used only to replace dependent types with
archetypes (or concrete types) within the opening context. We can do
the same simply by letting the constraint system create type variables
and then binding those type variables to the appropriate
archetypes/concrete types in that context.

Eliminate the two DependentTypeOpener entry points that were only used
by the ArchetypeOpener.

Subject: [PATCH 0788/1732] Add a bailout location # threshold in DSE.

In StdlibUnitTest, there is this function that has too many (2450) LSLocations
and the data flow in DSE takes too long to converge.

StdlibUnittest.TestSuite.(addForwardRangeReplaceableCollectionTests  (Swift.String, makeCollection : ([A.Generator.Element]) -> A, wrapValue : (StdlibUnittest.OpaqueValue) -> A.Generator.Element, extractValue : (A.Generator.Element) -> StdlibUnittest.OpaqueValue, makeCollectionOfEquatable : ([B.Generator.Element]) -> B, wrapValueIntoEquatable : (StdlibUnittest.MinimalEquatableValue) -> B.Generator.Element, extractValueFromEquatable : (B.Generator.Element) -> StdlibUnittest.MinimalEquatableValue, checksAdded : StdlibUnittest.Box>, resiliencyChecks : StdlibUnittest.CollectionMisuseResiliencyChecks, outOfBoundsIndexOffset : Swift.Int) -> ()).(closure #18)

This function alone takes ~20% of the total amount of time spent in DSE in StdlibUnitTest.

And DSE does not eliminate any dead store in the function either. I added this threshold
to abort on functions that have too many LSLocations.

I see no difference in # of dead store eliminated in the Stdlib.

Subject: [PATCH 0790/1732] [Mangler] Accelerate the decoding of characters
 from APInt.

Instead of dividing the number character by character we now extract 8
characters at once into a local 64bit variable and process this variable
locally. It is much faster to process a local variable because unlike APInt
we don't need to shift lots of words around or perform long division.

Subject: [PATCH 0792/1732] [Constraint system] Eliminate DependentTypeOpener.
 NFC

Eliminate the last client of DependentTypeOpener,
RequirementTypeOpener, which tracked the opened Self type when doing
witness/requirement matching and substituted in the known type
witnesses for that protocol. It had a bunch of dead logic hanging
around from the days where we used the constraint system to deduce
type witnesses. Now, a simple substitution suffices.

With its last client gone, remove DependentTypeOpener as well.

Subject: [PATCH 0793/1732] [Mangler] Accelerate the variable-length encoder
 (1/2).
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Before this change we were adding bits to an APInt bitstream by shifting and
adding on every character. With this commit we maintain a local 64-bit value
that we use as a local bitstream.  Once we reach the local variable capacity we
save the local value into the APInt bitstream. This reduces the number of shifts
on the bitstream from once per character to about once every eight characters.

This change speeds swift-compress that can now compress 60k mangled names per
second (and reduce the size by ~40%). This is anout 43MB of names in eight
seconds and includes the cost of the regular expression used by the tool (which
is 24% of runtime).

This commit changes the API of variable_encode so I had to re-generate the
header files. The change to the header file includes some of the changes
that I've made in previous commit. I’ll commit the auto-generated header files
in a separate commit to make the patch readable.

Subject: [PATCH 0795/1732] [StdLib] Refactor ObjC dependencies in Runtime
 tests

This change moves functionality that requires ObjC interop into a new file and
removes the XFAIL on Linux. Partially resolves SR-216.

Subject: [PATCH 0796/1732] [StdLib] Refactor ObjC dependencies in ArrayTraps
 test

This change moves functionality that requires ObjC interop into a new file and
removes the XFAIL on Linux. Partially resolves SR-216.

Subject: [PATCH 0797/1732] There are simply too many locations and too many
 basic blocks in some functions for dead store elimination to handle.  In the
 worst case, The number of memory behavior or alias queries we need to do is
 roughly linear to the # BBs x(times) # of locations.

Put in some heuristic to trade off accuracy for compilation time.

NOTE: we are not disabling DSE for these offending functions. instead we are running
a one iteration pessimistic data flow as supposed to the multiple iteration optimistic
data flow we've done previously.

With this change. I see compilation time on StdlibUnitTest drops significantly.
50%+ drop in time spent in DSE in StdlibUnit with a release compiler.

I will update more Instruments data post-commit once i get close to my desktop.

I see a slight drop in # of dead stores (DS) elimination in stdlib and stdlibUnit test.

stdlib: 203 DS -> 202 DS. (RLE is affected slightly as well. 6313 -> 6295 RL).

stdlibunittest :  43 DS -> 42. (RLE is not affected).

We are passing all existing dead store tests.

 deallocated in cast

This case was previously ignoring the DestroyOnFailure flag, so
we had a leak if a cast to an existential metatype failed for
certain types (tuples, structs, etc).

Subject: [PATCH 0802/1732] Re-convert omitNeedlessWords to be defined in terms
 of parameter lists instead of types, with a bugfix.  We make sure to check
 for DefaultArgumentKind::None instead of checking for the presence of a
 default value.  These are different when dealing with deserialized models and
 clang importer results.

Subject: [PATCH 0804/1732] Remove all dependencies on the stdlib from ARC
 Sequence Opts tests except for the uniqueness check tests

I did not change the uniqueness check tests since I think there is actual value
there in ensuring that the ARC optimizer is not moving around uniqueness checks
when actual stdlib containers are involved.

From e1ef60987c3ad46ad348521b5e9074fe3bdc9d9d Mon Sep 17 00:00:00 2001
From: Michael Gottesman 
Date: Sun, 3 Jan 2016 18:39:49 -0600
Subject: [PATCH 0816/1732] Revert "[codegardening] Move MemBehaviorDumper from
 AADumper.cpp into its own file MemoryBehaviorDumper.cpp." Revert "Make
 AADumper and MemoryBehaviorDumper function passes. They do not need to be
 module passes."

This reverts commit a503269e2d4a8739818002de3bc0f31a2814b071.
This reverts commit 375f525c51ef56a9a76918d57060778daefd9e74.

Turns out we /do/ want these two passes to be module passes so that their output
is independent of how the pass manager schedules function passes.

I tried to just fix the issue in MemBehaviorDumper/AADumper without reverting,
but somehow this caused their tests to start failing?!

I will try separating them again in a subsequent commit.

Subject: [PATCH 0819/1732] [codegardening] Add a new pass called
 RCIdentityDumper that dumps the RCIdentity of all values in all functions.

This allows for the RCIdentityAnalysis to be tested independent of other
passes.

Also add some initial tests for RCIdentity. I am stepping through "strip by
strip" but I did not have time to finish the coverage.

Subject: [PATCH 0822/1732] Rework the interface to coerceParameterListToType
 to make it obvious that it is specific to ClosureExprs.  Also, consolidate
 some logic in CSDiags into the now shared coerceParameterListToType, which
 makes a bit more sense and simplifies things a lot.  NFC.

There are still unanswered questions.  It isn't clear to me why
we support API names on closures, when we don't implement proper
semantic analysis for them. This seems like an accidentally supported
feature that should be removed.

Subject: [PATCH 0824/1732] [Compression] Increase the number of chars used on
 non APInt words.

This commit accelerates the performance of DecodeStringFromNumber by increasing
the number of characters that fit into a 64-bit word from 8 (conservative
estimate that we have 8bit ascii chars) to 10 (6-bit encoding).  We now compute
the number of characters that fit into a 64 bit word based on the length of the
character set at compile time.

Most other parts of `build-script-impl` print the unknown argument when
a switch statement fails to pattern match. Do the same for unknown
arguments passed to `--cross-compile-tools-deployment-targets`.

Subject: [PATCH 0834/1732] SILCombine: fix non-deterministic compilation

This is another bug exposed by changing the instruction allocation.
Depending on the allocated address of new SILBuilder instructions, those instructions were added to the SILCombiner worklist or not.
This bug didn't cause any crashes or miscombiles, but resulted in a non-deterministic result of SILCombine.

Subject: [PATCH 0835/1732] Take a more displined approach in DSE as to how to
 a function is optimized.

Now we have 3 cases.

1. OptimizeNone (for functions with too many basicblocks and too many locations). Simply return.
2. Pessimisitc single iteration data flow (for functions with many basic blocks and many locations).
3. Optimistic multiple iteration data flow (for functions with some basic blocks and some locations
   and require iterative data flow).

With this change stdlib and stdlibunittest has some changes in dead store(DS)
eliminated.

stdlib: 202 -> 203 DS.
stdlibunittest: 42 - 39 DS.

Compilation time improvement: with this change on a RELEASE+ASSERT compiler for stdlibunittest.

Subject: [PATCH 0842/1732] [Sema] Return nullptr less often when typechecking
 stmts. NFC.

There's a risk of untypechecked exprs like SequenceExpr leaking out to
the validator if we happen to generate a new statement but fail to
return it. For the sake of simplicity and consistency, try to always
return the statement that's been typechecked. The classes for which we
still return nullptr sometimes are the following: ForEachStmt,
ReturnStmt, BreakStmt, ContinueStmt, FallthroughStmt.

Subject: [PATCH 0844/1732] Use consistent formatting of header comments.

Correct format:
```
//===--- Name of file - Description ----------------------------*- Lang -*-===//
```

Notes:
* Comment line should be exactly 80 chars.
* Padding: Pad with dashes after "Description" to reach 80 chars.
* "Name of file", "Description" and "Lang" are all optional.
* In case of missing "Lang": drop the "-*-" markers.
* In case of missing space: drop one, two or three dashes before "Name of file".

Subject: [PATCH 0850/1732] Revert "Rework the interface to
 coerceParameterListToType to make it obvious"

This reverts commit 420bedaae15f070853c5ce8a77b6ce2405814b8d because it
appears to have unintentionally made some previously accepted code
involving casts of variadic parameters to closures no longer compile.

Subject: [PATCH 0858/1732] [Omit needless words] Use the getter name for BOOL
 properties.

Rather than employ complicated heuristics to determine when to add
"is" to the name of a Booleam property, just trust the name of the
getter.

Subject: [PATCH 0859/1732] James Campbell pointed out on swift-evolution that
 the [:] literal syntax for dictionaries is non-discoverable.  Fix that by
 having the compiler suggest a fixit hint to rewrite [] in a dictionary
 context to [:].

Subject: [PATCH 0861/1732] Use StaticString for `file` parameters in the

`assert`, etc., as well as `swift-corelibs-xctest`

The default initializer for a float types initializes the value to `0`
by calling a “builtin” function to convert an integer with value `0`
into an “FPIEEE” float with value `0`. The integer value is signed, but
the code was calling a function that expected an unsigned integer.

Subject: [PATCH 0868/1732] Improve IRGen's infrastructure for caching local
 type data.

There are several interesting new features here.

The first is that, when emitting a SILFunction, we're now able to
cache type data according to the full dominance structure of the
original function.  For example, if we ask for type metadata, and
we've already computed it in a dominating position, we're now able
to re-use that value; previously, we were limited to only doing this
if the value was from the entry block or the LLVM basic block
matched exactly.  Since this tracks the SIL dominance relationship,
things in IRGen which add their own control flow must be careful
to suppress caching within blocks that may not dominate the
fallthrough; this mechanism is currently very crude, but could be
made to allow a limited amount of caching within the
conditionally-executed blocks.

This query is done using a proper dominator tree analysis, even at -O0.
I do not expect that we will frequently need to actually build the
tree, and I expect that the code-size benefits of doing a real
analysis will be significant, especially as we move towards making
more metadata lazily computed.

The second feature is that this adds support for "abstract"
cache entries, which indicate that we know how to derive the metadata
but haven't actually done so.  This code isn't yet tested, but

Subject: [PATCH 0876/1732] Jordan pointed out that VarDecl::isSelfParameter
 really does need to check the implicit bit for decls, because otherwise we'd
 consider params declared with a name of `self` as being "the self parameter".

This is trivial, except for the fact that we don't serialize the
implicit bit on parameters.  I can't bring myself to burn encoding
space for this (particularly since we shouldn't be encoding self
decls in the first place!), so make the deserializer infer this bit
instead.

Subject: [PATCH 0877/1732] Refine the use and behavior of
 ConditionalDominanceScope.

Instead of categorically forbidding caching within a conditional
scope, permit it but remember how to remove the cache entries.
This means that ad-hoc emission code can now get exactly the
right caching behavior if they use this properly.  In keeping
with that, adjust a bunch of code to properly nest scopes
according to the conditional paths they enter.

Subject: [PATCH 0885/1732] [AddSwift.cmake] Remove leftover use_internal_sdk
 parameter values

The `use_internal_sdk` flag has been removed from `_add_variant_link_flags` and
`_add_variant_c_compile_flags` in commit
d9bbb6caf09a512f10edc4379194ec6a07aed847

In four instances where previously FALSE was given as the value for that
parameter, this value has not been removed from the call.
This causes the two functions to try to append flags to FALSE instead of the
respective link_flags and c_compile_flags variables.

Subject: [PATCH 0887/1732] Extend DefaultArgumentKind with cases for nil, [],
 and [:].

Under -enable-infer-default-arguments, the Clang importer infers some
default arguments for imported declarations. Rather than jumping
through awful hoops to make sure that we create default argument
generators (which will likely imply eager type checking), simply
handle these cases as callee-side expansions.

This makes -enable-infer-default-arguments usable, fixing
rdar://problem/24049927.

Subject: [PATCH 0892/1732] [Compression] Implement a new strategy for finding
 frequently used substrings.

The code-book compression (compression using a dictionary) shortens words by
encoding references to a string table.  This commit changes the code that
constructs the string table. Before we were scanning all of the substrings in
the input upto a certain length and we sorted them by frequency. The
disadvantage of that approach was that we encoded parts of substrings multiple
times. For example, the word "Collection" and the substring "ollec" had the same
frequency. Attempts to prune the list was too compute intensive and not very
effective (we checked if "ollec" is a substring of "Collection" and if they had
a similar frequency).

This commit implements a completely different approach. We now partition the
long words into tokens. For example, the string "ArrayType10Collection" is split
to "Array" + "Type" + "10Collection.

This method is very effective and with the updated tables we can now reduce the
size of the string table by 57%! This change also reduces the size of the string
table by 1/3.

With this change (the auto-generated h files, that are not included in this
commit) the size  of the swift dylib on x86 is reduced from 4.4MB to 3.6MB.

 failable casts

Overriding `AnySequence.dropFirst` and `AnySequence.prefix` to delegate
these operations to an underlying sequence, thus simplifying default

Subject: [PATCH 0901/1732] [Clang importer] Infer default argument [:] for
 some NSDictionary parameters.

Both option set (CF_OPTIONS/NS_OPTIONS) and NSDictionary parameters
tend to be used as option sets. The former already get a default
argument of []. This commit adds a default argument of [:] for the
latter, identified by a parameter whose argument label involves
"options", "attributes", or "userInfo".

Subject: [PATCH 0903/1732] [Build system] Add presets for Swift inside the
 LLDB tree.

This is useful when building LLDB configurations from Xcode that require the
Swift sources to be inside the LLDB tree.
While we still recommend checking out LLDB as a peer of llvm, clang, and swift,
and using build-script to automate the overall build, this allows LLDB to be
built from Xcode in the same way that it is in llvm.org.

Subject: [PATCH 0904/1732] Don't serialize full ConcreteDeclRefs for
 conformance value witnesses.

A protocol conformance needs to know what declarations satisfy requirements;
these are called "witnesses". For a value (non-type) witness, this takes the
form of a ConcreteDeclRef, i.e. a ValueDecl plus any generic specialization.
(Think Array rather than Array, but for a function.)

This information is necessary to compile the conformance, but it causes
problems when the conformance is used from other modules. In particular,
the type used in a specialization might itself be a generic type in the
form of an ArchetypeType. ArchetypeTypes can't be meaningfully used
outside their original context, however, so this is a weird thing to
have to deal with. (I'm not going to go into when a generic parameter is
represented by an ArchetypeType vs. a GenericTypeParamType, partially
because I don't think I can explain it well myself.)

The above issue becomes a problem when we go to use the conformance from
another module. If module C uses a conformance from module B that has a
generic witness from module A, it'll think that the archetypes in the
specialization for the witness belong in module B. Which is just wrong.

It turns out, however, that no code is using the full specializations for
witnesses except for when the conformance is being compiled and emitted.
So this commit sidesteps the problem by just not serializing the
specializations that go with the ConcreteDeclRef for a value witness.

This doesn't fix the underlying issue, so we should probably still see
if we can either get archetypes from other contexts out of value witness
ConcreteDeclRefs, or come up with reasonable rules for when they're okay
to use.

Subject: [PATCH 0907/1732] Dependencies: lookups in subscript signatures count
 as dependencies.

Fills in Chris's placeholder in feace85d5. I'm not quite sure why a private
subscript doesn't produce a non-cascading dependency right now, but this is
at least conservatively correct.

(For more infomation on dependencies, check out "Dependency Analysis.rst".)

Subject: [PATCH 0912/1732] [SIL] Let alloc_stack return a single value.

Having a separate address and container value returned from alloc_stack is not really needed in SIL.
Even if they differ we have both addresses available during IRGen, because a dealloc_stack is always dominated by the corresponding alloc_stack in the same function.

Although this commit quite large, most changes are trivial. The largest non-trivial change is in IRGenSIL.

This commit is a NFC regarding the generated code. Even the generated SIL is the same (except removed #0, #1 and @local_storage).

Subject: [PATCH 0916/1732] Change PointerIntEnum to a new better
 representation.

The big differences here are that:

1. We no longer use the 4096 trick.

2. Now we store all indices inline so no mallocing is required and the
value is trivially copyable. We allow for much larger indices to be
stored inline which makes having an unrepresentable index a much smaller
issue. For instance on a 32 bit platform, in NewProjection, we are able
to represent an index of up to (1 << 26) - 1, which should be more than
enough to handle any interesting case.

3. We can now have up to 7 ptr cases and many more index cases (with each extra
bit needed to represent the index cases lowering the representable range of
indices).

The whole data structure is much simpler and easier to understand as a
bonus. A high level description of the ADT is as follows:

1. A PointerIntEnum for which bits [0, (num_tagged_bits(T*)-1)] are not all
set to 1 represent an enum with a pointer case. This means that one can have
at most ((1 << num_tagged_bits(T*)) - 2) enum cases associated with
pointers.

2. A PointerIntEnum for which bits [0, (num_tagged_bits(T*)-1)] are all set
is either an invalid PointerIntEnum or an index.

3. A PointerIntEnum with all bits set is an invalid PointerIntEnum.

4. A PointerIntEnum for which bits [0, (num_tagged_bits(T*)-1)] are all set
but for which the upper bits are not all set is an index enum. The case bits
for the index PointerIntEnum are stored in bits [num_tagged_bits(T*),
num_tagged_bits(T*) + num_index_case_bits]. Then the actual index is stored
in the remaining top bits. For the case in which this is used in swift
currently, we use 3 index bits meaning that on a 32 bit system we have 26
bits for representing indices meaning we can represent indices up to
67_108_862. Any index larger than that will result in an invalid
PointerIntEnum. On 64 bit we have many more bits than that.

By using this representation, we can make PointerIntEnum a true value type
that is trivially constructable and destructable without needing to malloc
memory.

In order for all of this to work, the user of this needs to construct an
enum with the appropriate case structure that allows the data structure to
determine what cases are pointer and which are indices. For instance the one
used by Projection in swift is:

   enum class NewProjectionKind : unsigned {
     // PointerProjectionKinds
     Upcast = 0,
     RefCast = 1,
     BitwiseCast = 2,
     FirstPointerKind = Upcast,
     LastPointerKind = BitwiseCast,

     // This needs to be set to ((1 << num_tagged_bits(T*)) - 1). It
     // represents the first NonPointerKind.
     FirstIndexKind = 7,

     // Index Projection Kinds
     Struct = PointerIntEnumIndexKindValue<0, EnumTy>::value,
     Tuple = PointerIntEnumIndexKindValue<1, EnumTy>::value,
     Index = PointerIntEnumIndexKindValue<2, EnumTy>::value,
     Class = PointerIntEnumIndexKindValue<3, EnumTy>::value,
     Enum = PointerIntEnumIndexKindValue<4, EnumTy>::value,
     LastIndexKind = Enum,
   };

Subject: [PATCH 0921/1732] More resilient class layout tests

Looks like subclassing classes with resiliently-sized properties works,
as long as the subclass is @_fixed_layout, so let's ensure that's tested.

We don't want @_fixed_layout classes to be a thing though, and we still
can't handle changes to the number of stored properties in a base class,
so a couple of tests are disabled until I land some more patches.

early might have resulted in some performance regressions.

when the changes to unbundle this functionality from the inliner goes in.

Subject: [PATCH 0928/1732] [docs] LibraryEvolution.rst: What kind of changes
 are ABI-safe?

Update the Library Evolution ("Resilience") doc with a listing for every
top-level declaration kind (...except operators and imports, TODO) that
describes what should be an ABI-compatible change between releases of a
binary library shipped independently of a client app (say, because it's
part of the OS). Restructure the existing discussion of "fragility
attributes" to describe how each of those capabilities is affected when,
say, marking a struct as "fixed-layout".

Still a work in progress, and if something unexpected catches your eye
I'd like to hear about it. Note also that this does /not/ describe how
Swift behaves today; we still make many assumptions about types that
will not be valid in a "resilient" world.

-Fixed-layout Classes?
----------------------
-
-There is some benefit to knowing that a class has a fixed layout---that is,
-that the stored properties of the class and all its superclasses are guaranteed
-not to change in future versions of a library. This would, for example, allow
-the class's memory to be allocated on the stack, as long as it can be proven
-that no references to the class escape. However, such a constraint is unlikely
-to be provable in practice from outside the class's own module, where its
-primary operations are opaquely defined. Thus, until a tangible benefit has
-been demonstrated, the ``@fixed_layout`` attribute will not apply to classes.

-(Another benefit would be to simplify the calculations needed for the offsets
-of stored properties within classes. However, it's unclear that this would have
-any significant benefit, particularly when most public properties are
-manipulated through their accessors.)
+Supported Evolution
+===================
 
+This section describes the various changes that are safe to make when releasing
+a new version of a library, i.e. changes that will not break binary
+compatibility. They are organized by declaration type.
 
-Closed Enums
-~~~~~~~~~~~~
+Anything *not* listed in this document should be assumed unsafe.
 
-By default, a library owner may add new cases to a public enum between releases
-without breaking binary compatibility. As with structs, this results in a fair
-amount of indirection when dealing with enum values, in order to potentially
-accommodate new values.
 
-.. note::
+Top-Level Functions
+~~~~~~~~~~~~~~~~~~~
 
-    If an enum value has a known case, or can be proven to belong to a set of
-    known cases, the compiler is of course free to use a more efficient
-    representation for the value, just as it may discard fields of structs that
-    are provably never accessed.
+A public top-level function is fairly restricted in how it can be changed. The
+following changes are permitted:
 
-A library owner may opt out of this flexibility by marking the enum as
-``@closed``. A "closed" enum may not have any ``private`` or ``internal`` cases
-and may not add new cases in the future. This guarantees to clients that the
-enum cases are exhaustive.
+- Changing the body of the function.
+- Changing *internal* parameter names (i.e. the names used within the function
+  body, not the labels that are part of the function's full name).
+- Reordering generic requirements (but not the generic parameters themselves).
+- Adding a default value to a parameter.
+- Changing a default value is permitted but discouraged; it changes the meaning
+  of existing source code.
 
 .. note::
 
-    Were a "closed" enum allowed to have non-public cases, clients of the
-    library would still have to treat the enum as opaque and would still have
-    to be able to handle unknown cases in their ``switch`` statements.
+    Today's implementation of default values puts the evaluation of the default
+    value expression in the library, rather than in the client like C++ or C#.
+    This is problematic if we want to allow adding new default values.
 
-The ``@closed`` attribute takes a version number, just like ``@available``.
-This is so that clients can deploy against older versions of the library, which
-may have non-public cases in the enum. (In this case the client must manipulate
-the enum as if the ``@closed`` attribute were absent.)
+.. admonition:: TODO
 
-Even for default "open" enums, adding new cases should not be done lightly. Any
-clients attempting to do an exhaustive switch over all enum cases will likely
-not handle new cases well.
+    Is *removing* a default value something we want to allow? It breaks source
+    compatibility, but not binary compatibility under the inlining model. That
+    said, changing a default value is discouraged, and removing + adding is the
+    same thing.
 
-.. note::
+No other changes are permitted; the following are particularly of note:
 
-    One possibility would be a way to map new cases to older ones on older
-    clients. This would only be useful for certain kinds of enums, though, and
-    adds a lot of additional complexity, all of which would be tied up in
-    versions. Our generalized switch patterns probably make it hard to nail
-    down the behavior here.

+- A public function may not change its generic requirements.

-A Unifying Theme

+Top-Level Variables and Constants
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
-So far this proposal has talked about three separate ways to lock down on three
-separate Swift entities: structs, enums, and functions. Each of these has a
-different set of constraints it enforces on the library author and promises it
-makes to clients. However, they all follow a common theme of giving up the
-flexibility of future changes in exchange for improved performance and perhaps
-some semantic guarantees. As such, we could consider using a common attribute,
-say ``@fixed``, ``@inline``, or ``@fragile``; either way, all attributes in
-this section can be referred to as "fragility attributes".
+Given a public module-scope variable declared with ``var``, the following
+changes are permitted:
 
+- Adding (but not removing) a public setter to a computed variable.
+- Adding or removing a non-public setter.
+- Changing from a stored variable to a computed variable, or vice versa, as
+  long as a previously-public setter is not removed.
+- Changing the body of an accessor.
+- Adding or removing an observing accessor (``willSet`` or ``didSet``) to/from
+  an existing variable. This is effectively the same as modifying the body of a
+  setter.
+- Changing the initial value of a stored variable.
 
-Constants

+.. admonition:: TODO
+
+    We need to pin down how this interacts with the "Behaviors" proposal.
+    Behaviors that just change the accessors of a global are fine, but those
+    that provide new entry points are trickier.
 
-The ``let`` keyword creates a named constant whose value will not change for
-the lifetime of that entity; for a global or static constant, this lasts from
-when the constant is first accessed (and lazily initialized) until the end of

-to have different values for a constant---say, a string describing the
-library's copyright information.
+If a public setter is added after the property is first exposed (whether the
+property is stored or computed), it must be versioned independently of the
+property itself.
 
-In order to make use of a constant's value across library boundaries, the
-library owner may mark the constant as ``@inlineable``. As when applied to
-functions, the attribute takes a version number specifying which versions of
-the library will behave correctly if the value is inlined into client code.

+Giving Up Flexibility

+clients to access them more efficiently. This restricts changes a fair amount:
+
+- Adding a public setter to a computed variable is still permitted.
+- Adding or removing a non-public setter is still permitted.
+- Changing from stored to computed or vice versa is forbidden, because it would

+  clients may use the new implementations, or they may use the implementations
+  from the time they were compiled, or a mix of both.
+- Adding/removing observing accessors is likewise permitted but discouraged,
+  for the same reason.
+- Changing the initial value of a stored variable is still permitted.

+- Reordering any existing members, including stored properties.

+- Removing conformances to non-public protocols.
+
+The important most aspect of a Swift struct is its value semantics, not its
+layout.
+
+.. admonition:: TODO
+
+    We need to pin down how this, and the ``@fixed_layout`` attribute below,
+    interacts with the "Behaviors" proposal. Behaviors that just change the
+    accessors of a property are fine, but those that provide new entry points
+    are trickier.
+
+
+New Conformances
+----------------
+
+If a conformance is added to a type in version 1.1 of a library, it's important
+that it isn't accessed in version 1.0. This is obvious if the protocol itself
+was introduced in version 1.1, but needs special handling if both the protocol
+and the type were available earlier. In this case, the conformance *itself*
+needs to be labeled as being introduced in version 1.1, so that the compiler
+can enforce its safe use.
+
+.. note::
+
+    This may feel like a regression from Objective-C, where `duck typing` would
+    allow a ``Wand`` to be passed as an ``id `` without ill effects.
+    However, ``Wand`` would still fail a ``-conformsToProtocol:`` check in
+    version 1.0 of the library, and so whether or not the client code will work
+    is dependent on what should be implementation details of the library.
 
-By default, a stored property in a struct or class may be replaced by a
-computed property in later versions of a library. As shown above, the
-``@fixed_layout`` attribute promises that all stored properties currently in a
-type will remain stored in all future library versions, but sometimes that
-isn't a reasonable promise. In this case, a library owner may still want to
-allow clients to rely on a *specific* stored property remaining stored, by
-applying the ``@fixed`` attribute to the property.
+We've considered two possible syntaxes for this::
+
+    @available(1.1)
+    extension MyStruct : SomeProto {…}
+
+and
+
+::
+
+    extension MyStruct : @available(1.1) SomeProto {…}
+
+The former requires fewer changes to the language grammar, but the latter could
+also be used on the declaration of the type itself (i.e. the ``struct``
+declaration).
+
+If we went with the former syntax, applying ``@available`` to an extension
+would override the default availability of entities declared within the
+extension; unlike access control, entities within the extension may freely
+declare themselves to be either more or less available than what the extension
+provides.
+
+
+Fixed-layout Structs
+--------------------
+
+To opt out of this flexibility, a struct may be marked ``@fixed_layout``. This
+promises that no stored properties will be added to or removed from the struct,
+even ``private`` or ``internal`` ones. In effect:
+
+- Reordering stored properties relative to one another is not permitted.
+  Reordering all other members is still permitted.
+- Adding new stored properties (public or non-public) is not permitted.
+  Adding any other new members is still permitted.
+- Existing properties may not be changed from stored to computed or vice versa.
+- Changing the body of any *existing* methods, initializers, or accessors is
+  permitted.
+- Adding or removing observing accessors from public stored properties is still
+  permitted.
+- Removing stored properties is not permitted. Removing any other non-public
+  members is still permitted.
+- Adding a new protocol conformance is still permitted.
+- Removing conformances to non-public protocols is still permitted.
+
+The ``@fixed_layout`` attribute takes a version number, just like
+``@available``. This is so that clients can deploy against older versions of
+the library, which may have a different layout for the struct. (In this case
+the client must manipulate the struct as if the ``@fixed_layout`` attribute
+were absent.)
+
+.. admonition:: TODO
+
+    There's a benefit to knowing that a struct was ``@fixed_layout`` since it
+    was first made available. How should that be spelled?
+
+.. admonition:: TODO
+
+    We really shouldn't care about the *order* of the stored properties.
+
+.. admonition:: TODO
+
+    Because observing accessors can still be added to public stored properties,
+    we don't get efficient setters unless they are also marked ``@inlineable``.
+    This seems suboptimal.
+
+.. admonition:: TODO
+
+    There are implementation concerns when the non-public fields do not have
+    public types. We probably just want to ban that configuration; otherwise,
+    clients will silently get slow performance copying the struct around.

+    be useful, and they require essentially the same implementation work as
+    cases added in future versions of a library.
 
-- ``no_payload``: Promises that an enum does not have payloads on any of its
-  cases (even the non-public ones).

-Collectively these features are known as "performance assertions", to

+    This states that adding/removing ``indirect`` (on either a case or the
+    entire enum) is considered a breaking change. Is that what we want?
+
+
+Closed Enums
+------------
+
+A library owner may opt out of this flexibility by marking the enum as
+``@closed``. A "closed" enum may not have any ``private`` or ``internal`` cases
+and may not add new cases in the future. This guarantees to clients that the
+enum cases are exhaustive. In particular:
+
+- Adding new cases is not permitted
+- Reordering existing cases is not permitted.
+- Adding a raw type to an enum that does not have one is still permitted.
+- Removing a non-public case is not applicable.
+- Adding any other members is still permitted.
+- Removing any non-public members is still permitted.
+- Adding a new protocol conformance is still permitted.
+- Removing conformances to non-public protocols is still permitted.
+

+
+    Were a "closed" enum allowed to have non-public cases, clients of the
+    library would still have to treat the enum as opaque and would still have
+    to be able to handle unknown cases in their ``switch`` statements.
+
+The ``@closed`` attribute takes a version number, just like ``@available``.
+This is so that clients can deploy against older versions of the library, which
+may have non-public cases in the enum. (In this case the client must manipulate
+the enum as if the ``@closed`` attribute were absent.)
+
+Even for default "open" enums, adding new cases should not be done lightly. Any
+clients attempting to do an exhaustive switch over all enum cases will likely
+not handle new cases well.
+
+.. note::
+
+    One possibility would be a way to map new cases to older ones on older
+    clients. This would only be useful for certain kinds of enums, though, and
+    adds a lot of additional complexity, all of which would be tied up in
+    versions. Our generalized switch patterns probably make it hard to nail
+    down the behavior here.
+
+
+Protocols
+~~~~~~~~~
+
+There are very few safe changes to make to protocols:
+
+- A new requirement may be added to a protocol, as long as it has an
+  unconstrained default implementation.
+- A new optional requirement may be added to an ``@objc`` protocol.
+- All members may be reordered, including associated types.
+
+However, any members may be added to protocol extensions, and non-public
+members may always be removed from protocol extensions.
+
+.. admonition:: TODO
+
+    We don't have an implementation model hammered out for adding new
+    defaulted requirements, but it is desireable.
 
-All of these features take a version number, just like the more semantic
-fragility attributes above. The exact spelling is not proposed by this document.
+
+Classes
+~~~~~~~
+
+Because class instances are always accessed through references, they are very
+flexible and can change in many ways between releases. Like structs, classes
+support all of the following changes:
+
+- Reordering any existing members, including stored properties.
+- Adding any new members, including stored properties, **except initializers**.
+- Changing existing properties from stored to computed or vice versa.
+- Changing the body of any methods, initializers, or accessors.
+- Adding or removing an observing accessor (``willSet`` or ``didSet``) to/from
+  an existing property. This is effectively the same as modifying the body of a
+  setter.
+- Removing any non-public members, including stored properties.
+- Adding a new protocol conformance (with proper availability annotations).
+- Removing conformances to non-public protocols.
+
+Initializers require special care, because a convenience initializer in a
+publicly-subclassable class depends on the presence of a designated initializer
+in the subclass. Adding a new designated initializer could thus break existing
+subclasses, unless previously-available *convenience* initializers are
+restricted from invoking newer designated initializers.
+
+New convenience initializers can always be added, although they will not be
+present on subclasses. New ``required`` initializers can *never* be added
+unless the class is not publicly subclassable.
+
+.. note:: If this sounds confusing, it's because our initializer model is
+  mostly a formalization of Objective-C's with extra safety constraints.
+  We'd like to revisit it at some point.
+
+Adding *or* removing ``final`` from a class or any of its members is not an
+ABI-safe change. The presence of ``final`` enables optimization; its absence
+means there may be subclasses/overrides that would be broken by the change.
+
+.. note:: This ties in with the ongoing discussions about
+  "``final``-by-default" and "non-publicly-subclassable-by-default".
+
+
+Possible Restrictions on Classes
+--------------------------------
+
+In addition to ``final``, it may be useful to restrict the size of a class
+instance (like a struct's ``@fixed_layout``) or the number of overridable
+members in its virtual dispatch table. These annotations have not been designed.
+
+
+Extensions
+~~~~~~~~~~
+
+Extensions largely follow the same rules as the types they extend.
+
+- Adding new extensions and removing empty extensions is always permitted.
+- Adding or removing members within a non-protocol extension follows the same
+  rules as the base type.
+- Adding members to a protocol extension is always permitted.
+- Removing non-public members from a protocol extension is always permitted.
+- Reordering members in extensions is always permitted.
+- Changing the bodies of any member in an extension is always permitted.
+- Moving a member from one extension to another within a module is always
+  permitted, as long as both extensions have the exact same constraints.
+- Moving a member from a non-protocol extension to the declaration of the base
+  type within the same module is always permitted.
+
+
+A Unifying Theme
+~~~~~~~~~~~~~~~~
+
+So far this proposal has talked about ways to give up flexibility for several
+different kinds of declarations: ``@inlineable`` for functions,
+``@fixed_layout`` for structs, etc. Each of these has a different set of
+constraints it enforces on the library author and promises it makes to clients.
+However, they all follow a common theme of giving up the flexibility of future
+changes in exchange for improved performance and perhaps some semantic
+guarantees. Therefore, all of these attributes are informally referred to as
+"fragility attributes".
+
+Given that these attributes share several characteristics, we could consider
+converging on a single common attribute, say ``@fixed``, ``@inline``, or
+``@fragile``. However, this may be problematic if the same declaration has
+multiple kinds of flexibility, as in the description of classes above.

-library. Someone files a bug, and it gets fixed in version 1.1.
-
-Now, what happens when this client code is deployed against version 1.0 of the
-library?
-
-::
-
-    // Library
-    @available(1.0)
-    public func classifyMagicItem(item: Item) -> MagicKind
-    
-    // Client
-    let kind = classifyMagicItem(elderWand)
-    log("\(elderWand): \(kind)")
-
-In order to call ``classifyMagicItem``, the client code needs access to the
-conformance of ``Wand`` to the ``MagicType`` protocol. But that conformance
-*didn't exist* in version 1.0, so the client program will fail on older systems.
-
-Therefore, a library author needs a way to declare that a type *now* conforms
-to a protocol when it previously didn't. The way to do this is by placing
-availability information on an extension::
-
-    @available(1.1)
-    extension Wand : MagicType {}
-
-Note that this is unnecessary if either ``Wand`` or ``MagicType`` were itself
-introduced in version 1.1; in that case, it would not be possible to access
-the conformance from a context that only required 1.0.
-
-As with access control, applying ``@available`` to an extension overrides the
-default availability of entities declared within the extension; unlike access
-control, entities within the extension may freely declare themselves to be
-either more or less available than what the extension provides.
-
-.. note::
-
-    This may feel like a regression from Objective-C, where `duck typing` would
-    allow a ``Wand`` to be passed as an ``id `` without ill effects.
-    However, ``Wand`` would still fail a ``-conformsToProtocol:`` check in
-    version 1.0 of the library, and so whether or not the client code will work
-    is dependent on what should be implementation details of the library.

 PointerTy <-> (void *).

This will enable PointerIntEnum to be used with PointerLikeTypes that are not

Subject: [PATCH 0936/1732] SIL: Add a new alloc_global instruction

If a global variable in a module we are compiling has a type containing
a resilient value type from a different module, we don't know the size
at compile time, so we cannot allocate storage for the global statically.

Instead, we will use a buffer, just like alloc_stack does for archetypes
and resilient value types.

This adds a new SIL instruction but does not yet make use of it.

Subject: [PATCH 0939/1732] [lit] The cmp() function should be treated as gone
 in Python 3

As noted in the "What's New in Python 3.0" [1] documentation the Python
2 `cmp` function no longer exists in Python 3. The document goes on to
say that if you really need the `cmp` function you should define your
own.

Since the function appears to only be used once in the script I defined
a local function rather than shadow the Python 2 function. The local
function, `_cmp`, implements the recommended expression from the "What's
New in Python 3.0" document. The behavior is now defined on both Python
2 and 3.

Subject: [PATCH 0940/1732] [docs] Address some of Slava's feedback on
 LibraryEvolution.rst.

(but not all of it)

- Add a note about throwing functions becoming non-throwing.
- Clarify that let-properties may not be turned into read-only vars.
- Permit new static stored properties on fixed_layout structs.
- Drop note about "fixed_layout-since-first-available".
- Add note disparaging the utility of @fixed.
- Add note about adding defaulted associated types to protcols.
- Clarify which members can and cannot be added to a class.
- Add some class-specific permitted changes.
- Note that adding/removing 'dynamic' is /not/ permitted.
- Split up protocol and non-protocol extensions.
- Explain why the 'no_payload' performance assertion isn't needed.

Saving the rest of the feedback for the next major content addition.

+ARC Sequence Optimization
+=========================
+
+TODO: Fill this in.
+
+ARC Loop Hoisting
+=================
+
+Abstract
+--------
+
+This section describes the ARCLoopHoisting algorithm that hoists retains and
+releases out of loops. This is a high level description that justifies the
+correction of the algorithm and describes its design. In the following
+discussion we talk about the algorithm conceptually and show its safety and
+considerations necessary for good performance.
+
+*NOTE* In the following when we refer to "hoisting", we are not just talking
+about upward code motion of retains, but also downward code motion of releases.
+
+Loop Canonicalization
+---------------------
+
+In the following we assume that all loops are canonicalized such that:
+
+1. The loop has a pre-header.
+2. The loop has one backedge.
+3. All exiting edges have a unique exit block.
+
+Motiviation
+-----------
+
+Consider the following simple loop::
+
+  bb0:
+    br bb1
+
+  bb1:
+    retain %x                    (1)
+    apply %f(%x)
+    apply %f(%x)
+    release %x                   (2)
+    cond_br ..., bb1, bb2
+
+  bb2:
+    return ...
+
+When it is safe to hoist (1),(2) out of the loop? Imagine if we know the trip
+count of the loop is 3 and completely unroll the loop so the whole function is
+one basic block. In such a case, we know the function looks as follows::
+
+  bb0:
+    # Loop Iteration 0
+    retain %x
+    apply %f(%x)
+    apply %f(%x)
+    release %x                   (4)
+
+    # Loop Iteration 1
+    retain %x                    (5)
+    apply %f(%x)
+    apply %f(%x)
+    release %x                   (6)
+
+    # Loop Iteration 2
+    retain %x                    (7)
+    apply %f(%x)
+    apply %f(%x)
+    release %x
+
+    return ...
+
+Notice how (3) can be paired with (4) and (5) can be paired with (6). Assume
+that we eliminate those. Then the function looks as follows::
+
+  bb0:
+    # Loop Iteration 0
+    retain %x
+    apply %f(%x)
+    apply %f(%x)
+
+    # Loop Iteration 1
+    apply %f(%x)
+    apply %f(%x)
+
+    # Loop Iteration 2
+    apply %f(%x)
+    apply %f(%x)
+    release %x
+
+    return ...
+
+We can then re-roll the loop, yielding the following loop::
+
+  bb0:
+    retain %x                    (8)
+    br bb1
+
+  bb1:
+    apply %f(%x)
+    apply %f(%x)
+    cond_br ..., bb1, bb2
+
+  bb2:
+    release %x                   (9)
+    return ...
+
+Notice that this transformation is equivalent to just hoisting (1) and (2) out
+of the loop in the original example. This form of hoisting is what is termed
+"ARCLoopHoisting". What is key to notice is that even though we are performing
+"hoisting" we are actually pairing releases from one iteration with retains in
+the next iteration and then eliminating the pairs. This realization will guide
+our further analysis.
+
+Correctness
+-----------
+
+In this simple loop case, the proof of correctness is very simple to see
+conceptually. But in a more general case, when is safe to perform this
+optimization? We must consider three areas of concern:
+
+1. Are the retains/releases upon the same reference count? This can be found
+   conservatively by using RCIdentityAnalysis.
+
+2. Can we move retains, releases in the unrolled case as we have specified?
+   This is simple since it is always safe to move a retain earlier and a release
+   later in the dynamic execution of a program. This can only extend the life of
+   a variable which is a legal and generally profitable in terms of allowing for
+   this optimization.
+
+3. How do we pair all necessary retains/releases to ensure we do not unbalance
+   retain/release counts in the loop? Consider a set of retains and a set of
+   releases that we wish to hoist out of a loop. We can only hoist the retain,
+   release sets out of the loop if all paths in the given loop region from the
+   entrance to the backedge.  have exactly one retain or release from this set.
+
+4. Any early exits that we must move a retain past or a release by must be
+   compensated appropriately. This will be discussed in the next section.
+
+Assuming that our optimization does all of these things, we should be able to
+hoist with safety.
+
+Compensating Early Exits for Lost Dynamic Reference Counts
+----------------------------------------------------------
+
+Lets say that we have the following loop canonicalized SIL::
+
+  bb0(%0 : $Builtin.NativeObject):
+    br bb1
+
+  bb1:
+    strong_retain %0 : $Builtin.NativeObject
+    apply %f(%0)
+    apply %f(%0)
+    strong_release %0 : $Builtin.NativeObject
+    cond_br ..., bb2, bb3
+
+  bb2:
+    cond_br ..., bb1, bb4
+
+  bb3:
+    br bb5
+
+  bb4:
+    br bb5
+
+  bb6:
+    return ...
+
+Can we hoist the retain/release pair here? Lets assume the loop is 3 iterations
+and we completely unroll it. Then we have::
+
+  bb0:
+    strong_retain %0 : $Builtin.NativeObject               (1)
+    apply %f(%0)
+    apply %f(%0)
+    strong_release %0 : $Builtin.NativeObject              (2)
+    cond_br ..., bb1, bb4
+
+  bb1: // preds: bb0
+    strong_retain %0 : $Builtin.NativeObject               (3)
+    apply %f(%0)
+    apply %f(%0)
+    strong_release %0 : $Builtin.NativeObject              (4)
+    cond_br ..., bb2, bb4
+
+  bb2: // preds: bb1
+    strong_retain %0 : $Builtin.NativeObject               (5)
+    apply %f(%0)
+    apply %f(%0)
+    strong_release %0 : $Builtin.NativeObject              (6)
+    cond_br ..., bb3, bb4
+
+  bb3: // preds: bb2
+    br bb5
+
+  bb4: // preds: bb0, bb1, bb2
+    br bb5
+
+  bb5: // preds: bb3, bb4
+    return ...
+
+We want to be able to pair and eliminate (2)/(3) and (4)/(5). In order to do
+that, we need to move (2) from bb0 into bb1 and (4) from bb1 into bb2. In order
+to do this, we need to move a release along all paths into bb4 lest we lose
+dnymaic releases along that path. We also sink (6) in order to not have an extra
+release along that path. This then give us::
+
+  bb0:
+    strong_retain %0 : $Builtin.NativeObject               (1)
+
+  bb1:
+    apply %f(%0)
+    apply %f(%0)
+    cond_br ..., bb2, bb3
+
+  bb2:
+    cond_br ..., bb1, bb4
+
+  bb3:
+    strong_release %0 : $Builtin.NativeObject              (6*)
+    br bb5
+
+  bb4:
+    strong_release %0 : $Builtin.NativeObject              (7*)
+    br bb5
+
+  bb5: // preds: bb3, bb4
+    return ...
+
+An easy inductive proof follows.
+
+What if we have the opposite problem, that of moving a retain past an early
+exit. Consider the following::
+
+  bb0(%0 : $Builtin.NativeObject):
+    br bb1
+
+  bb1:
+    cond_br ..., bb2, bb3
+
+  bb2:
+    strong_retain %0 : $Builtin.NativeObject
+    apply %f(%0)
+    apply %f(%0)
+    strong_release %0 : $Builtin.NativeObject
+    cond_br ..., bb1, bb4
+
+  bb3:
+    br bb5
+
+  bb4:
+    br bb5
+
+  bb6:
+    return ...
+
+Lets unroll this loop::
+
+  bb0(%0 : $Builtin.NativeObject):
+    br bb1
+
+  # Iteration 1
+  bb1: // preds: bb0
+    cond_br ..., bb2, bb8
+
+  bb2: // preds: bb1
+    strong_retain %0 : $Builtin.NativeObject               (1)
+    apply %f(%0)
+    apply %f(%0)
+    strong_release %0 : $Builtin.NativeObject              (2)
+    br bb3
+
+  # Iteration 2
+  bb3: // preds: bb2
+    cond_br ..., bb4, bb8
+
+  bb4: // preds: bb3
+    strong_retain %0 : $Builtin.NativeObject               (3)
+    apply %f(%0)
+    apply %f(%0)
+    strong_release %0 : $Builtin.NativeObject              (4)
+    br bb5
+
+  # Iteration 3
+  bb5: // preds: bb4
+    cond_br ..., bb6, bb8
+
+  bb6: // preds: bb5
+    strong_retain %0 : $Builtin.NativeObject               (5)
+    apply %f(%0)
+    apply %f(%0)
+    strong_release %0 : $Builtin.NativeObject              (6)
+    cond_br ..., bb7, bb8
+
+  bb7: // preds: bb6
+    br bb9
+
+  bb8: // Preds: bb1, bb3, bb5, bb6
+    br bb9
+
+  bb9:
+    return ...
+
+First we want to move the retain into the previous iteration. This means that we
+have to move a retain over the cond_br in bb1, bb3, bb5. If we were to do that
+then bb8 would have an extra dynamic retain along that path. In order to fix
+that issue, we need to balance that release by putting a release in bb8. But we
+cannot move a release into bb8 without considering the terminator of bb6 since
+bb6 is also a predecessor of bb8. Luckily, we have (6). Notice that bb7 has one
+predecessor to bb6 so we can safely move 1 release along that path as well. Thus
+we perform that code motion, yielding the following::
+
+  bb0(%0 : $Builtin.NativeObject):
+    br bb1
+
+  # Iteration 1
+  bb1: // preds: bb0
+    strong_retain %0 : $Builtin.NativeObject               (1)
+    cond_br ..., bb2, bb8
+
+  bb2: // preds: bb1
+    apply %f(%0)
+    apply %f(%0)
+    strong_release %0 : $Builtin.NativeObject              (2)
+    br bb3
+
+  # Iteration 2
+  bb3: // preds: bb2
+    strong_retain %0 : $Builtin.NativeObject               (3)
+    cond_br ..., bb4, bb8
+
+  bb4: // preds: bb3
+    apply %f(%0)
+    apply %f(%0)
+    strong_release %0 : $Builtin.NativeObject              (4)
+    br bb5
+
+  # Iteration 3
+  bb5: // preds: bb4
+    strong_retain %0 : $Builtin.NativeObject               (5)
+    cond_br ..., bb6, bb8
+
+  bb6: // preds: bb5
+    apply %f(%0)
+    apply %f(%0)
+    cond_br ..., bb7, bb8
+
+  bb7: // preds: bb6
+    strong_release %0 : $Builtin.NativeObject              (7*)
+    br bb9
+
+  bb8: // Preds: bb1, bb3, bb5, bb6
+    strong_release %0 : $Builtin.NativeObject              (8*)
+    br bb9
+
+  bb9:
+    return ...
+
+Then we move (1), (3), (4) into the single predecessor of their parent block and
+eliminate (3), (5) through a pairing with (2), (4) respectively. This yields
+then::
+
+  bb0(%0 : $Builtin.NativeObject):
+    strong_retain %0 : $Builtin.NativeObject               (1)
+    br bb1
+
+  # Iteration 1
+  bb1: // preds: bb0
+    cond_br ..., bb2, bb8
+
+  bb2: // preds: bb1
+    apply %f(%0)
+    apply %f(%0)
+    br bb3
+
+  # Iteration 2
+  bb3: // preds: bb2
+    cond_br ..., bb4, bb8
+
+  bb4: // preds: bb3
+    apply %f(%0)
+    apply %f(%0)
+    br bb5
+
+  # Iteration 3
+  bb5: // preds: bb4
+    cond_br ..., bb6, bb8
+
+  bb6: // preds: bb5
+    apply %f(%0)
+    apply %f(%0)
+    cond_br ..., bb7, bb8
+
+  bb7: // preds: bb6
+    strong_release %0 : $Builtin.NativeObject              (7*)
+    br bb9
+
+  bb8: // Preds: bb1, bb3, bb5, bb6
+    strong_release %0 : $Builtin.NativeObject              (8*)
+    br bb9
+
+  bb9:
+    return ...
+
+Then we finish by rerolling the loop::
+
+  bb0(%0 : $Builtin.NativeObject):
+    strong_retain %0 : $Builtin.NativeObject               (1)
+    br bb1
+
+  # Iteration 1
+  bb1: // preds: bb0
+    cond_br ..., bb2, bb8
+
+  bb2:
+    apply %f(%0)
+    apply %f(%0)
+    cond_br bb1, bb7
+
+  bb7:
+    strong_release %0 : $Builtin.NativeObject              (7*)
+    br bb9
+
+  bb8: // Preds: bb1, bb3, bb5, bb6
+    strong_release %0 : $Builtin.NativeObject              (8*)
+    br bb9
+
+  bb9:
+    return ...
+
+
+Uniqueness Check Complications
+------------------------------
+
+A final concern that we must consider is if we introduce extra copy on write
+copies through our optimization. To see this, consider the following simple
+IR sequence::
+
+  bb0(%0 : $Builtin.NativeObject):
+    // refcount(%0) == n
+    is_unique %0 : $Builtin.NativeObject
+    // refcount(%0) == n
+    strong_retain %0 : $Builtin.NativeObject
+    // refcount(%0) == n+1
+
+If n is not 1, then trivially is_unique will return false. So assume that n is 1
+for our purposes so no copy is occuring here. Thus we have::
+
+  bb0(%0 : $Builtin.NativeObject):
+    // refcount(%0) == 1
+    is_unique %0 : $Builtin.NativeObject
+    // refcount(%0) == 1
+    strong_retain %0 : $Builtin.NativeObject
+    // refcount(%0) == 2
+
+Now imagine that we move the strong_retain before the is_unique. Then we have::
+
+  bb0(%0 : $Builtin.NativeObject):
+    // refcount(%0) == 1
+    strong_retain %0 : $Builtin.NativeObject
+    // refcount(%0) == 2
+    is_unique %0 : $Builtin.NativeObject
+
+Thus is_unique is guaranteed to return false introducing a copy that was not
+needed. We wish to avoid that if it is at all possible.

This is not true in non-loop canonicalized SIL. It is true in loop-canonicalized

Allocate and project the buffer, respectively, adding the

For now we don't emit alloc_global instructions anywhere;
an upcoming change will add that at the SIL level.

Also I suspect debug info needs some work to handle the

Subject: [PATCH 0949/1732] Introduce ProtocolConformanceRef.  NFC.

The main idea here is that we really, really want to be
able to recover the protocol requirement of a conformance
reference even if it's abstract due to the conforming type
being abstract (e.g. an archetype).  I've made the conversion
from ProtocolConformance* explicit to discourage casual
contamination of the Ref with a null value.

As part of this change, always make conformance arrays in
Substitutions fully parallel to the requirements, as opposed
to occasionally being empty when the conformances are abstract.

As another part of this, I've tried to proactively fix
prospective bugs with partially-concrete conformances, which I
believe can happen with concretely-bound archetypes.

In addition to just giving us stronger invariants, this is
progress towards the removal of the archetype from Substitution.

Subject: [PATCH 0953/1732] Add the stand-alone devirtualizer pass back to the
 pipeline.

It looks like this has minimal performance impact either way. Once the
changes to make the inliner a function pass are committed, the position
of this in the pipeline will change.

Subject: [PATCH 0954/1732] [IRGen] Convert existential metatypes test to SIL

Convert a test in order to test the SIL parser and avoid the front end. The
updated test verifies that conformances for the init_existential_metatype
instruction are calculated correctly. The matching functionality was added in
commit 2df68806.

Subject: [PATCH 0955/1732] Add the stand-alone generic specializer pass back
 to the pipeline.

On the whole it looks like this currently benefits performance.

As with the devirtualization pass, once the updated inliner is
committed, the position of this pass in the pipeline will change.

Subject: [PATCH 0973/1732] Remove confusing `incIfSigned` control flow

This function was named exactly backwards (it incremented only when
*not* signed). Investigating this naming error revealed that the call
site was also unclear: `incIfSigned` was called from a block where
`signed` was known to be False). So, I inlined the logic in the one
place where it was actually used, and removed the function.

Subject: [PATCH 0985/1732] [Compression] Accelerate the decompression of
 mangled strings.

This commit accelerates the phase in the decompression that encodes strings as
long numbers. This is optimization is similar to the code that we have in the
compressor where we perform as much arithmetic as possible on local 64-bit
values before we push them to the APInt. This change accelerates the compression
by about 2x.

Subject: [PATCH 0993/1732] SILGen: Emit alloc_global when initializing global
 variables

It is still not clear to me when we access global variables from other
modules directly, versus using accessors; it seems to be controlled
by the -sil-serialize-all flag, rather than any language feature.

Until/if we add a @_fixed_layout equivalent for globals, I can't really
test direct access of globals from other modules; when we figure out
the story here I'll be able to add more tests and also tighten up
some isResilient() checks in the global code, but what's in there now
seems to work.

Subject: [PATCH 0994/1732] IRGen: Add ResilienceExpansion parameter to
 TypeInfo::isKnownEmpty(), NFC

In a few places, we have to be careful about the distinction between
"empty in this resilience domain" versus "empty in all resilience
domains". Make callers think about this by adding a parameter instead
of relying on them to check isFixedSize() as necessary first.

While making this change I noticed that the code for checking if
types are empty when computing extra inhabitants of structs and enums
might be slightly wrong in the face of resilience; I will revisit
this later.

Subject: [PATCH 0996/1732] [Sema] Fix crash in addCurriedSelfType
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

isGenericContext() returning true doesn’t necessarily imply that getGenericSignature() returns non-null. getGenericSignatureOfContext() performs a traversal equivalent to isGenericContext(), so we use it instead.

Subject: [PATCH 0997/1732] Handle indirect conformance when devirtualizing
 existentials.

While I'm in this code, generalize it to propagate the original
type information in more cases, including when the original type
is still dependent, and teach it to handle existential metatypes.

Subject: [PATCH 1003/1732] [AST] Fix inconsistent handling of generic args &
 params during BoundGenericType::getSubstitutions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A decl’s full GenericSignature is set during validateGenericTypeSignature().

Then during ConstraintSystem::openTypes(), in ReplaceDependentTypes, the GenericArgs list is built from the generic signature (via getGenericParamTypes()) and passed into a new BoundGenericType.

In BoundGenericType::getSubstitutions(), the GenericArgs are assumed to match getGenericParamsOfContext()->getParams().

However, in reality, the GenericArgs include all levels of generic args, whereas getGenericParamsOfContext() are the params of the innermost context only, so the params array is accessed past its end.

This commit changes NominalTypeDecl::getGenericParamTypes() to return the innermost params, in order to match the output of BoundGenericType::getGenericArgs(). For clarity and to hopefully prevent future confusion, we also rename getGenericParamTypes() to getInnermostGenericParamTypes().

Subject: [PATCH 1006/1732] [test] Fail if a test file uses StdlibUnittest but
 runs no tests.

This catches accidental omission of runAllTests(). Previously
such test files would silently test nothing and succeed.

 setter without a getter, create a dummy getter to avoid breaking downstream
 invariants.  This fixes three crashers, including one added by

Subject: [PATCH 1017/1732] Make sure that even in the standalone build
 configuration, we can build doxygen documentation.

The issue is that this was originally done when in-tree builds were the
preferred way of building so LLVM_ENABLE_DOXYGEN would be defined and LLVM would
have found doxygen as well. When one is doing the current preferred standalone
install, the option LLVM_ENABLE_DOXYGEN is not discoverable to the user via an
option with a default argument and the doxygen package is never searched for.

This commit ensures that when building standalone:

1. LLVM_ENABLE_DOXYGEN is defined as an option with a default value of FALSE.
2. The cmake dtrace package is searched for and found.

When we are building standalone, we take these values from LLVM.

Subject: [PATCH 1018/1732] Fix a bug that I noticed when doing the parameter
 rework, where we'd accidentally accept closure arguments with API names (but
 only in a parenthesized parameter list). While it could theoretically be
 interesting to support API names on closures, this is never something we
 intended to support, and a lot of implementation work would be necessary to
 make them correct.  Just correctly reject them even if parenthesized.

Subject: [PATCH 1021/1732] [SR-427][AST] Report DoesNotConform for failed
 substitutions in a bound generic type.

If a BoundGenericType is unable to get a substitution for an archetype
it uses ErrorType as the replacement (Module.cpp:705). In such a case
we should report DoesNotConform in lookupConformance(), which ends up
generating reasonable error messages. Prior to this change the
conformance would succeed and then IRGen would crash on emitting an
ErrorType during emitForeignTypeMetadataRef().

Also added test that tickles crash near the same place as SR-427.

Subject: [PATCH 1024/1732] [Compression] Accelerate the code that decodes
 chars from var-length streams.

This change accelerates the code that decodes characters from bitstreams
(represented using APInts) that are encoded using variable length encoding. The
idea is simple: Extract the lowest 64 bit and decode as many characters as
possible before changing the bignum. Decoding words from a local variable is
much faster than changing big nums. This commit makes decompression twice as
fast as compression.

Subject: [PATCH 1026/1732] Revert "[StdLib] Extend ReflectionHashing test to
 pass on Linux"

This test expects consistent hash code generation on any given platform.
However String instance generate different values on Linux depending on which
version of libicu is installed, causing environment-specific test failures.

This reverts commit def419b57fbce2391eb16c4c203c4db996dc5b97.

Subject: [PATCH 1027/1732] fix rdar://24029542 "Postfix '.' is reserved" error
 message" isn't helpful

This adds some heuristics so we can emit a fixit to remove extraneous
whitespace after a . and diagnose the case where a member just hasn't
been written yet better.  This also improves handling of tok::unknown
throughout the parser a bit.

Subject: [PATCH 1028/1732] Clean up handling of external declarations, NFC

This is the first in a series of patches that fixes some resilience-related
issues with synthesized accessors and materializeForSet.

Previously we maintained two lists of external declarations encountered while
type checking:

- ASTContext::ExternalDefinitions
- TypeChecker::implicitlyDefinedFunctions

The former contained the following:

- Imported nominal types from Clang, so that SILGen can emit witness tables
- Functions and variables with Clang decls, so that IRGen can instruct Clang
  to emit them
- Synthesized accessors

The latter contained synthesized functions for derived conformances.

Since the second list was not visible outside Sema, we relied on the Clang
importer to add the type that contained the declaration to the
ExternalDefinitions list. In practice, we only synthesized members of enums
in this manner.

Because of this, SILGenModule::emitExternalDefinitions() had special logic to
skip members of enums, since it would visit them when visiting the enum itself.

Instead, it appears that we can remove implicitlyDefinedFunctions completely,
changing usage sites to add the decl to ExternalDefinitions instead, and
simplify SILGenModule::emitExternalDefinition() a bit in the process.

Also, it looks like we never had Modules appear in ExternalDefinitions, so
assert if those come up instead of skipping them.

Subject: [PATCH 1031/1732] SILGen: Split off SILGenMaterializeForSet.cpp from
 SILGenLValue.cpp, NFC

In order to fix some other issues that came up with materializeForSet
and resilience, I had to bite the bullet and finish off John's code
for open-coding materializeForSet emission in SILGen. This patch
makes the subsequent changes easier to review.

Subject: [PATCH 1033/1732] Introduce DiagnosticState to track how we should
 handle diagnostics

Refactor DiagnosticEngine to separate out diagnostic state
tracking. This allows gives us a base from which to add further
refinements, e.g. warning suppression.

Subject: [PATCH 1035/1732] Add ignoreAllWarnings API

New API on DiagnosticEngine to disable the reporting of warnings. No
tests currently, as this is not exposed upwards to any test-able
level, but tests will come when this is exposed e.g. through command
line arguments.

Subject: [PATCH 1045/1732] fix rdar://24029542 "Postfix '.' is reserved" error
 message" isn't helpful

This adds some heuristics so we can emit a fixit to remove extraneous
whitespace after a . and diagnose the case where a member just hasn't
been written yet better.  This also improves handling of tok::unknown
throughout the parser a bit.

This is a re-commit of ff4ea54 with an update for a SourceKit test.

Subject: [PATCH 1048/1732] Remove the case 'Invalid' from the TermKind enum
 and just use an unreachable in the ValueKind -> TermKind switch instead.

In all of the cases where this is being used, we already immediately perform an
unreachable if we find a TermKind::Invalid. So simplify the code and move it
into the conversion switch itself.

Subject: [PATCH 1049/1732] Distinguish conformance and superclass generic
 requirements.

As part of this, use a different enum for parsed generic requirements.

NFC except that I noticed that ASTWalker wasn't visiting the second
type in a conformance constraint; fixing this seems to have no effect
beyond producing better IDE annotations.

Subject: [PATCH 1054/1732] Generalize the conditions in which we'll accept an
 ambiguous solution to a constraint system in "allowFreeTypeVariables" mode. 
 Previously, we only allowed a few specific constraints, now we allow any
 relational and member constraints.  The later one is a big deal because it
 means that we can allow ".Foo" expressions as ambiguous solutions, which
 CSDiags can handle well.

This unblocks solving 23942743 and enables some minor improvements across
the board, including diagnosing things like this better:
  Optional(.none)  // now: generic parameter 'T' could not be inferred

That said, it also just permutes some non-awesome diagnostics.

Subject: [PATCH 1060/1732] Fix rdar://19710848 QoI: Friendlier error message
 for "[] as Set"

This makes diagnoseGeneralConversionFailure more conservative: it
now never diagnoses a failed conversion when it involves a type that
has unresolved type in it.  These types could not be resolved, so it
is better to let ambiguity resolution handle the problem.

On "[] as Set", we would previously get:
  error: 'Set<_>' is not convertible to 'Set'
now we get:
  error: generic parameter 'Element' could not be inferred

Subject: [PATCH 1061/1732] fix  [QoI] Bad diagnostic
 when errors inside enum constructor

On something like this:
  let x = .Tomato(cloud: .None)

we previously emitted a "type of expression is ambiguous without more context" error
while pointing to .None.  With a previous fix, we now produce the same error pointing
to the .Tomato.  With this fix, we now produce:

error: reference to member 'Tomato' cannot be resolved without a contextual type

to really drive the problem home.

Subject: [PATCH 1062/1732] SILGen: Always open-code materializeForSet

This improves MaterializeForSetEmitter to support emission
of static materializeForSet thunks, as well as witnesses.

This is now done by passing in a nullptr as the conformance
and requirement parameters, and adding some conditional code.

Along the way, I fixed a few limitations of the old code,
namely weak/unowned and static stored properties weren't
completely plumbed through. There was also a memory leak in
addressed materializeForSet, the valueBuffer was never freed.

Finally, remove the materializeForSet synthesis in Sema since
it is no longer needed, which fixes at least one known crash
case.

Subject: [PATCH 1064/1732] [docs] Add a "Lexicon" file that defines common
 Swift jargon terms.

Inspired by LLVM's similar file. (Thanks for reminding me about that, Chris!)

+.. title:: Lexicon
+.. default-role:: term
+
+.. @raise litre.TestsAreMissing
+
+This file defines several terms used by the Swift compiler and standard library
+source code, tests, and commit messages. See also the `LLVM lexicon`_.
+
+.. _LLVM lexicon: http://llvm.org/docs/Lexicon.html
+
+.. glossary::
+
+  archetype
+    A placeholder for a generic parameter or an associated type within a
+    generic context.
+
+  canonical SIL
+    SIL after the
+    `mandatory passes ` have run.
+    This can be used as input to IRGen to generate LLVM IR or object files.
+
+  Clang importer
+    The part of the compiler that reads C and Objective-C declarations and
+    exposes them as Swift. Essentially contains a small instance of Clang
+    running inside the Swift compiler, which is also used during IRGen.
+
+  conformance
+    A construct detailing how a particular type conforms to a particular
+    protocol. Represented in the compiler by the ProtocolConformance type at
+    the AST level. See also `witness table`.
+
+  DI (definite initialization / definitive initialization)
+    The feature that no uninitialized variables, constants, or properties will
+    be read by a program, or the analysis pass that operates on SIL to
+    guarantee this. This was `discussed on Apple's Swift blog`__.
+    
+    __ https://developer.apple.com/swift/blog/?id=28
+
+  existential
+    A value whose type is a protocol composition (including a single protocol
+    and *zero* protocols; the latter is the ``Any`` type).
+
+  fragile
+    Describes a type or function where making changes will break binary
+    compatibility. See :doc:`LibraryEvolution.rst `.
+
+  IUO (implicitly unwrapped optional)
+    A type like Optional, but it implicitly converts to its wrapped type. If
+    the value is ``nil`` during such a conversion, the program traps just as
+    it would when a normal Optional is force-unwrapped. IUOs implicitly
+    convert to and from normal Optionals with the same wrapped type.
+
+  main module
+    The module for the file or files currently being compiled.
+
+  mandatory passes / mandatory optimizations
+    Transformations over SIL that run immediately after SIL generation. Once
+    all mandatory passes have run (and if no errors are found), the SIL is
+    considered `canonical `.
+
+  metatype
+    The type of a value representing a type. Greg Parker has a good
+    explanation of `Objective-C's "metaclasses"`__; because Swift has types
+    that are *not* classes, a more general term is used.
+    
+    We also sometimes refer to a value representing a type as a "metatype
+    object" or just "metatype", usually within low-level contexts like IRGen
+    and LLDB. This is technically incorrect (it's just a "type object"), but
+    the malapropism happened early in the project and has stuck around.
+  
+    __ http://sealiesoftware.com/blog/archive/2009/04/14/objc_explain_Classes_and_metaclasses.html
+    
+  model
+    A type that conforms to a particular protocol. Sometimes "concrete
+    model". Example: "Array and Set are both models of CollectionType".
+
+  module
+    Has *many* uses in the Swift world. We may want to rename some of them.
+    #1 and #2 are the most common.
+    
+    1. A unit of API distribution and grouping. The ``import`` declaration 
+       brings modules into scope. Represented as ModuleDecl in the compiler.
+    2. A compilation unit; that is, source files that are compiled together.
+       These files may contain cross-references. Represented as "the main
+       module" (a specific ModuleDecl).
+    3. (as "SIL module") A container for SIL to be compiled together, along
+       with various context for the compilation.
+    4. (as "LLVM module") A collection of LLVM IR to be compiled together.
+       Always created in an LLVMContext.
+    5. A file containing serialized AST and SIL information for a source file
+       or entire compilation unit. Often "swiftmodule file", with "swiftmodule"
+       pronounced as a single word.
+    6. (as "Clang module") A set of self-contained C-family header files.
+       Represented by a ClangModuleUnit in the Swift compiler, each of which is
+       contained in its own ModuleDecl. For more information, see
+       `Clang's documentation for Modules`__.
+    7. Shorthand for a "precompiled module file"; effectively "precompiled

+       See also `module cache`.
+    
+    __ http://clang.llvm.org/docs/Modules.html
+
+  module cache
+    Clang's cache directory for precompiled module files. As cache files, these
+    are not forward-compatible, and so cannot be loaded by different versions
+    of Clang (or programs using Clang, like the Swift compiler). Normally this
+    is fine, but occasionally a development compiler will not have proper
+    version information and may try to load older module files, resulting in
+    crashes in ``clang::ASTReader``.
+
+  open existential
+    An `existential` value with its dynamic type pulled out, so that the 
+    compiler can do something with it.
+
+  PR
+    1. "Problem Report": An issue reported in `LLVM's bug tracker`__. 
+       See also `SR`.
+    2. "pull request"

+  resilient
+    Describes a type or function where making certain changes will not break
+    binary compatibility. See :doc:`LibraryEvolution.rst `.
+
+  script mode
+    The parsing mode that allows top-level imperative code in a source file.
+
+  SIL
+    "Swift Intermediate Language". A high-level IR used by the Swift compiler
+    for flow-sensitive diagnostics, optimization, and LLVM IR generation.
+
+  -sil-serialize-all
+    A mode where all functions in a library are made available for inlining by
+    any client, regardless of access control. Also called "magic performance
+    mode" as a reminder of how this drastically changes compilation. Not
+    guaranteed to work on arbitrary code.
+
+  SR
+    An issue reported on `bugs.swift.org `_. A
+    backronym for "Swift Report"; really the name is derived from LLVM's
+    idiomatic use of "PR" ("Problem Report") for its bugs. We didn't go with
+    "PR" for Swift because we wanted to be able to unambiguously reference
+    LLVM bugs.
+
+  trap
+    A deterministic runtime failure. Can be used as both as a noun ("Using an
+    out-of-bounds index on an Array results in a trap") and a verb
+    ("Force-unwrapping a nil Optional will trap").
+
+  type metadata
+    The runtime representation of a type, and everything you can do with it.
+    Like a ``Class`` in Objective-C, but for any type.
+
+  value witness table
+    A runtime structure that describes how to do basic operations on an unknown
+    value, like "assign", "copy", and "destroy". (For example, does copying
+    this value require any retains?)
+
+    Only conceptually related to a `witness table`.
+
+  vtable (virtual dispatch table)
+    A map attached to a class of which implementation to use for each
+    overridable method in the class. Unlike an Objective-C method table,
+    vtable keys are just offsets, making lookup much simpler at the cost of
+    dynamism and duplicated information about *non*-overridden methods.
+
+  witness
+    The value or type that satisfies a protocol requirement.
+
+  witness table
+    The SIL (and runtime) representation of a `conformance`; essentially a
+    `vtable ` but for a protocol instead of
+    a class.
+
+    Only conceptually related to a `value witness table`.
+
+  WMO (whole-module optimization)
+    A compilation mode where all files in a module are compiled in a single
+    process. In this mode there is no `primary file`; all files are parsed,
+    type-checked, and optimized together at the SIL level. LLVM optimization
+    and object file generation may happen all together or in separate threads.

Subject: [PATCH 1067/1732] Fix rdar://22509125 QoI: Error when unable to infer
 generic archetype lacks greatness

Rearrange diagnoseGeneralConversionFailure to diagnose structural problems
even if we have some UnresolvedTypes floating around, then reject constraint
failures with UnresolvedTypes in them even harder.  This keeps us giving
good errors about failures where we have a structural problem (with buried
irrelevant details) while not complaining about cases that are actually
ambiguous.

The end result of this is that we produce a lot better error messages in the
case of failed archetype inference.  This also highlights the poor job we do
handling multi-stmt closureexprs...

Subject: [PATCH 1071/1732] SILGen: Correctly emit accessors synthesized to
 witness protocol requirements

We weren't adding them as external decls unless they were for
storage on an imported type, which meant SILGen wasn't emitting
them if the conforming type was from a different Swift source
file, or in whole-module mode, a different module. This led
to linker errors.

Instead, always add accessors to the external decl list, but
skip them in SILGen if they are contained in the DeclContext
we are currently emitting (which is a source file or module).

Note that they are still emitted with the wrong linkage, from a
resilience perspective. Clients must only ever see public
exports for getters, setters and materializeForSet emitted
because they are required by resilience or the access pattern;
'accidental' accessors synthesized for protocol conformance
should not be public.

Subject: [PATCH 1074/1732] Fix rdar://20395243 QoI: type variable
 reconstruction failing for tuple types

ASTPrinter of type variables was trying to dig an original type out of the
locator and archetype that opened the type variable in the first place.  This
was prone to failure and never helped, so just always print type vars as _.

The affected diagnostics always come out better and this saves a word of storage
for each type variable.

Subject: [PATCH 1089/1732] [Driver] Make the list of input files available
 when creating Jobs.

Previously jobs had to grovel this information out of the raw argument
list, which dropped the types we had inferred on input files. This
makes things more consistent across the compiler, though arguably we
should be able to designate "primary" and "non-primary" inputs on a
per-action basis rather than resorting to "global" state.

Use this new information to stop passing object file inputs to the
Swift frontend, fixing rdar://problem/23213785.

The list wouldn't have to live on the Compilation, but I'm going to use
it to fix SR-280 / rdar://problem/23878192 as well.

Subject: [PATCH 1102/1732] Refactor SILArgument to use TermKind and refactor a
 bunch of the code there to use one helper function to find incoming values.

This improves the quality of code but more importantly makes it easier to ensure
that new terminators are handled in this code since all of the switches are now
covered switches.

Subject: [PATCH 1103/1732] [gyb] Force UTF-8 encoding when parsing templates
 on Linux

Python 3 on Linux reads the system locale information to determine what
it should use as the default encoding for strings read from files (this
is different from OS X which is always UTF-8 by default [1]).

Since all the Swift gyb templates are UTF-8 encoded there is effectively
no reason to parse them as anything else. This patch forces the gyb
template parser to read the template using UTF-8 encoding. It accounts
for both reading and writing to a file as well as reading from stdin and
writing to stdout.

Two changes of note are that it now includes a __future__ import that
should make Python 2 behave a little closer to Python 3 in terms of
unicode support. Additionally Python 2 can no longer use cStringIO
because it does not support unicode [2].

To test this patch I ran these commands before and after the patch.
Note: that before the patch if the locale was set to something other
than UTF-8, ASCII for instance, the Python 3 runs would fail. See [3]
for example failure message.

Without stdin/stdout:

$ python2 utils/gyb -o Arrays.2.7.swift stdlib/public/core/Arrays.swift.gyb
$ python3 utils/gyb -o Arrays.3.5.swift stdlib/public/core/Arrays.swift.gyb
$ diff -u Arrays.2.7.swift Arrays.3.5.swift

With stdin/stdout:

$ cat stdlib/public/core/Arrays.swift.gyb | python2 utils/gyb > Arrays.2.7.stdin.stdout.swift
$ cat stdlib/public/core/Arrays.swift.gyb | python3 utils/gyb > Arrays.3.5.stdin.stdout.swift
$ diff -u Arrays.2.7.stdin.stdout.swift Arrays.3.5.stdin.stdout.swift

Subject: [PATCH 1107/1732] [Driver] Allow passing all source files in a
 filelist.

Generate frontend commands with -filelist in them. This isn't actually
implemented yet, but we can start testing at this point.

Subject: [PATCH 1109/1732] Teach the frontend about -filelist for input files.

With this, we're out of the business of passing large numbers of input
files on the command line to the frontend, which means we no longer
overflow argv with a mere 1100 input files under whole-module optimization.

In order to make sure this doesn't happen again, I'd like to also get
this working for
- swiftmodule inputs to the merge-module build phase
- /output/ files for multithreading single-frontend builds (WMO)
- object file inputs to the linker on OS X (response files for binutils
  ld have different quoting rules)

Part 3 of https://bugs.swift.org/browse/SR-280.

Instead of fail silently, issue a diagosis when a valid expression can not
be parsed for enum raw value.

This resolves [SR-510](https://bugs.swift.org/browse/SR-510).

Subject: [PATCH 1123/1732] Fix some bugs in the dominance-caching logic.

Most notably, the source caches did not respect dominance.  The
simplest solution was just to drop them in favor of the ordinary
caching system; this is unfortunate because it requires walking
over the path twice instead of exploiting the trie, but it's much
easier to make this work, especially in combination with the other
caching mechanisms at play.

This will be tested by later commits that enable lazy-loading of
local type data in various contexts.

Subject: [PATCH 1125/1732] Remove @inline(never) hacks that were added for the
 lack of ARC across loops

After the recent improvements to the ARC optimizer these should not longer be
necessary and I did not measure negative performance impact from removing them.

Subject: [PATCH 1126/1732] Port a util "getTypeFromMangledTypename" from lldb
 (lldb/source/Symbol/SwiftASTContext.cpp) to IDE and add some tests against
 it.

This utility helps us reconstruct type from a mangled name. SourceKit needs this functionality to deliver
richer doc-info/cursor-info.

Thanks for Sean's help!

Subject: [PATCH 1137/1732] Add a swift3_migration attribute to describe how an
 API gets migrated.

Introduce a new attribute, swift3_migration, that lets us describe the
transformation required to map a Swift 2.x API into its Swift 3
equivalent. The only transformation understood now is "renamed" (to
some other declaration name), but there's a message field where we can
record information about other changes. The attribute can grow
somewhat (e.g., to represent parameter reordering) as we need it.

Right now, we do nothing but store and validate this attribute.

Subject: [PATCH 1141/1732] [SR-511][Parse] Add 'associatedtype' keyword and
 fixit
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds an associatedtype keyword to the parser tokens, and accepts either
typealias or associatedtype to create an AssociatedTypeDecl, warning
that the former is deprecated. The ASTPrinter now emits associatedtype
for AssociatedTypeDecls.

Separated AssociatedType from TypeAlias as two different kinds of
CodeCompletionDeclKinds. This part probably doesn’t turn out to be
absolutely necessary currently, but it is nice cleanup from formerly
specifically glomming the two together.

And then many, many changes to tests. The actual new tests for the fixits
is at the end of Generics/associated_types.swift.

Subject: [PATCH 1143/1732] [Driver] Pass -filelist to Darwin 'ld' too.

Start sketching out a way for individual jobs to request filelists for
their inputs or their outputs. This should cover all the cases mentioned
in ad945426.

Subject: [PATCH 1145/1732] [Driver] Write the all-sources file even under
 -save-temps.

We optimize subprocess invocation to a simple execve() if there's no
cleanup work to do, but that doesn't get us out of doing /setup/ work.

Subject: [PATCH 1147/1732] [Driver] Use filelists for the *output* of a
 threaded WMO build.

This is only the driver side of the work; the frontend doesn't understand
this new -output-filelist option yet. Next commit.

Subject: [PATCH 1148/1732] Teach the frontend about -output-filelist.

Finishes up https://bugs.swift.org/browse/SR-280. At this point, nothing
should be passing O(N) arguments on the command line, where N is the
number of input source files, unless N is small.

(There are other inputs which are passed through to subtools, and these
are not put into filelists. That's fine.)

From f1682cd9a8e010eb477f2f90bac8f162c76ceadc Mon Sep 17 00:00:00 2001
From: John McCall

Subject: [PATCH 1151/1732] Use real types instead of "Self" for the IR value
 names of local type data.

Since that's somewhat expensive, allow the generation of meaningful
IR value names to be efficiently controlled in IRGen.  By default,
enable meaningful value names only when generating .ll output.

I considered giving protocol witness tables the name T:Protocol
instead of T.Protocol, but decided that I didn't want to update that
many test cases.

Subject: [PATCH 1170/1732] [StdLib] Update requirements for UnicodeUTFEncoders
 test

All of the tests in this file need the Objective-C runtime. This change removes
the XFAIL on linux and replaces it with a runtime requirement.

Subject: [PATCH 1171/1732] [Clang importer] Teach importFullName to provide
 argument labels for functions.

importFullName was inconsistent in the kinds of names it produced for
imported C functions. swift_name'd functions would get argument
labels, but non-swift_name'd functions would not, and other parts of
the important were working around the oddity. Make importFullName()
always provide the argument labels.

Subject: [PATCH 1172/1732] XCTest Overlay: Add XCTAssertThrowsError assertion

Add an assertion that can be used to check that an expression throws an
error, and if it does to run a block against that error which may
contain further checks.

Addresses rdar://problem/23789904.

Subject: [PATCH 1173/1732] XCTest Overlay: Allow assertion expressions to
 throw

When an assertion expression throws an error, treat that as an
unexpected failure of the assertion.

Also generate the failure message for the error directly in the overlay,
rather than routing through _XCTFailureDescription, to avoid revlock
between the overlay and XCTest.framework's implementation.

Subject: [PATCH 1175/1732] SIL: Split up AbstractionPattern::isOpaque() into
 two predicates

- isTypeParameter() -- check if this is an archetype or dependent
  interface type.

- requiresClass() -- check if this is a class-constrained type
  parameter.

The old isOpaque() check has been replaced by
(isTypeParameter() && !requiresClass(moduleDecl)).

This allows us to pass the ModuleDecl on down to
GenericSignature::requiresClass(), enabling the use of
interface types in abstraction patterns.

NFC for now.

Subject: [PATCH 1176/1732] [Diagnostics] Refactor and clarify diagnostic
 behavior rules.

Restores StoredDiagnosticInfo, which is useful to help distinguish
when the user explicitly modifies the behavior of a diagnostic vs
we're just picking up the default kind.

Adds some clarifying comments, and lays out the suppression workflow,
whereby different types of suppression (per-diagnostic, per-category,
etc) have different precedence levels.

Subject: [PATCH 1177/1732] [SourceKit] Omit internal parameters from filter
 name

The internal parameter names are just there to give an extra hint in the
source text for what the argument is. Consequently, we don't want to
allow filtering to match against them.

Subject: [PATCH 1178/1732] [Diagnostics] Remove all categories

Diagnostic categories are entirely unused and arguably useless as
implemented, as they merely denote the sub-component of the
compiler.

As far as categorizing warnings are concerned, I'm abandoning the
effort for now, as the utility is marginal and Swift and the Swift
compiler are probalby not ready for these to be nailed down. For the
sake of cleanliness, the CATEGORY field is also stripped from
WARNINGS.

If there's a need for automatic identifying of compiler sub-components
for diagnstics in the future, there are better ways to do this.

Subject: [PATCH 1184/1732] Revert "[literal-sil] Do not print out import Swift
 when we are compiling the stdlib."

This reverts commit bc4ed2a3b0edcd761ed93577b972a1bc4817d111.

I need to fix some of the validation tests.

Subject: [PATCH 1186/1732] [rc-id] Make RCIdentity strip off single-pred
 arguments.

In a bunch of use-cases we use stripSinglePredecessorArgs to eliminate this
case. There is no reason to assume that this is being done in the caller of
RCIdentity. Lets make sure that we handle this case here.

Subject: [PATCH 1192/1732] Add powerpc64le Linux support

This patch adds powerpc64le Linux support. While the patch also adds
the matching powerpc64 bits, there are endian issues that need to be
sorted out.

The PowerPC LLVM changes for the swift ABI (eg returning three element
non-homogeneous aggregates) are still in the works, but a simple LLVM
fix to allow those aggregates results in swift passing all but 8
test cases.

Subject: [PATCH 1193/1732] [SR-381]: runtime resolution of type metadata from
 a name

replace ProtocolConformanceTypeKind with TypeMetadataRecordKind

metadata reference does not need to be indirectable

more efficient check for protocol conformances

remove swift_getMangledTypeName(), not needed yet

kill off Remangle.cpp for non-ObjC builds

cleanup

cleanup

Subject: [PATCH 1194/1732] IRGen: Stop using SIL
 TypeConverter::getArchetypes() in type lowering, NFC

Let's use the ArchetypeBuilder from the ASTContext, which was
recently added by Doug.

Also refactor away GenericsRAII helper class.

Subject: [PATCH 1195/1732] SIL: Stop using TypeConverter::getArchetypes() in
 type lowering, NFC

Now that we can ask questions of a generic signature directly,
we can pass dependent types right on through to TypeClassifierBase
without consulting getArchetypes().

This required a small fix to getTypeLowering() to correctly form
an abstraction pattern from an interface type.

There are no remaining usages of getArchetypes(), so that
entire ArchetypeBuilder instance is now gone.

Also refactor away SIL's take on the GenericsRAII helper class.

Subject: [PATCH 1201/1732] [test] Don't double-quote strings passed to shells.

%swift_driver_plain should already be quoted; embedding it in single
quotes again could in theory mess things up.

Noticed by inspection.

Subject: [PATCH 1202/1732] [test] Disable shebang test on Linux.

This test creates a shebang (#!) line that may exceed 80 characters, which is
a limit on many systems. Instead, use /usr/bin/env to invoke the right 'swift'.

OS X is more permissive (up to PATH_MAX characters), so continue testing the
direct invocation there.

Subject: [PATCH 1210/1732] REVERTME: Disallow partial application of super
 methods except for implicit self

This adds a Sema check that super methods aren't partially applied,
since we are removing currying declaration syntax. Once that lands,
this can be reverted and the test removed.

Subject: [PATCH 1211/1732] Don't assert on alloc_stack with only
 debug_value_addr uses.

This came up with other changes I have to modify the optimizer
pipeline. We shouldn't assert if we have an alloc_stack/dealloc_stack
where the only other use of the alloc_stack is a debug_value_addr.

It's easy to avoid this by removing allocations that don't have real
uses prior to attempting to handle the ones that do have real uses (as
opposed to the other way around).

Subject: [PATCH 0447/1732] Explicitly restrict NRVO optimization to "out"
 args.

Don't allow this optimization to kick in for "inout" args.
The optimization may expose local writes to any aliases of the argument.
I can't prove that is memory safe.

Erik pointed out this case.

Subject: [PATCH 0450/1732] Clang importer: centralize the "suppress
 declaration import" logic.

The Swift name lookup tables and the complete Objective-C "container"
to Swift DeclContext mapping code used similar-but-different logic to
determine when to suppress a declaration (e.g., when suppressing the
accessors for a property). Centralize the logic so we get the same
behavior in both places.

Enum constants are naturally going to be named after their ObjC name,
not their Swift name. As such, ignore the swift_name attr on the enum

simpler anyway as it also bypasses the swift_private handling that the
code was already trying to work around.

Subject: [PATCH 0452/1732] Fix  Crash on Subscript
 taking a tuple argument list

by changing buildSubscriptIndexReference to work solely in terms of the parameter
pattern of the subscript, instead of trying to walk the index type in parallel to
extract parameter labels.

Subject: [PATCH 0455/1732] [Mangler] Fix all of the places where users of the
 Mangler access the underlying buffer.

This commit fixes all of the places where users of the Mangler write to the stream that's used by the Mangler. The plan is to make the Mangler buffered, and this means that users can't assume that the mangler immediately writes the mangled tokens to the output stream.

Subject: [PATCH 0456/1732] Use a separate valueenumerator for alias cache and
 memory behavior cache

If we use a shared valueenumerator, imagine the case when one of the AAcache or MBcache
is cleared and we clear the valueenumerator.

This could give rise to collisions (false positives) in the not-yet-cleared cache!

Subject: [PATCH 0457/1732] fix  = vs. == in Swift if
 string character count statement causes segmentation fault

This is a really nasty problem where we'd explode trying to unify type variables
we found in the constraint graph, that didn't exist in the constraint system.  This
happened because diagnostic generation is simplifying the system in
"ContinueAfterFailures" mode to try to get to a minimal system (to avoid
producing an error message about trivially solvable constraints that only
exist due to the solver stopping early) and in this mode we would see an
erroneous constraint, remove it from the constraint system, but not the
constraint graph.  This only mattered in ContinueAfterFailures.

As with many things, the fix is pretty simple once the onion is peeled enough
to find the stinky part lurking inside.

Subject: [PATCH 0463/1732] Include access functions for the metadata and
 witness tables of associated types in protocol witness tables.

We use the global access functions when the result isn't
dependent, and a simple accessor when the result can be cheaply
recovered from the conforming metadata.  Otherwise, we add a
cache slot to a private section of the witness table, forcing
an instantiation per conformance.  Like generic type metadata,
concrete instantiations of generic conformances are memoized.

There's a fair amount of code in this patch that can't be
dynamically tested at the moment because of the widespread
reliance on recursive expansion of archetypes / dependent
types.  That's something we're now theoretically in a position
to change, and as we do so, we'll test more of this code.

Subject: [PATCH 0467/1732] IRGen: Calculate access pattern for class metadata
 members

This tells us if the superclass field offsets are non-constant,
in which case they have to be copied in.

This will be used to simplify some code and plug in value type
resilience.

ClassLayoutBuilder computes a bunch of stuff in addition to the
StructLayout, which is then stashed in ClassTypeInfo. Extract this
into a new ClassLayout type. It probably should not exist at all,
if we only generalized StructLayout a bit.

Subject: [PATCH 0472/1732] IRGen: Move field offset global emission out of
 Objective-C-specific code

We're going to start using these for pure Swift classes as well,
when they have a resilient superclass, or fields of resilient
value type.

Subject: [PATCH 0481/1732] Remove obsolete BridgeStorage.swift.gyb test.

The functionality this is testing looks like it's been subsumed by the Builtin.BridgeObject type. This is the only thing keeping alive the otherwise dead _swift_usesNativeSwiftReferenceCounting_nonNull runtime stub.

Subject: [PATCH 0492/1732] Eagerly update a protocol's "has missing required
 members" flag.

Rather than plumbing a "has missing required members" flag all the way
through the LazyResolver's loadAllMembers and its implementations,
just eagerly update the "has missing required members" flag in the
Clang importer when it happens. More NFC cleanup.

Subject: [PATCH 0495/1732] SpriteKit overlay: remove the subscript from SKNode

In iOS 8.0/OS X 10.10, SpriteKit introduced an
-objectForKeyedSubscript: method that enabled subscripting in
Objective-C. However, this subscript wasn't generally useful in Swift
because it took AnyObject and produced AnyObject, so the SpriteKit
overlay defined a subscript that took a String and produced an
[SKNode].

Subsequently, in iOS 9.0/OS X 10.10, -objectForKeyedSubscript: got
type annotations that gave it the appropriate Swift signature, which
made the subscript defined in the overlay redundant.

The twisty logic of the Clang importer would suppress the imported
subscript when it saw the one in the overlay, hiding the
redundancy. My cleanup of that logic in
0c0a0fab4b8c2a824882fd1dd68379f94a878055 caused uses of the subscript
to be redundant.

Removal of the redundant code in the overlay is the overall best
answer, because it minimizes the size of the overlay and leaves the
API in the Objective-C header. However, this will introduce a
regression for SpriteKit applications targeting iOS 7.0/OS X 10.8,
where the overlay was compensating for the lack of this operation
before iOS 8.0 / OS X 10.8. There are workarounds here we can
investigate, although they're fairly hacky.

Subject: [PATCH 0500/1732] [ClangImporter] Add a bunch of non-null assertions.

rdar://problem/23985987 has a crash report that implies that a null
snuck in here at some point in the past. All the refactoring that's
happened since then probably means it can't happen any more, but
assertions are always good, right?

Getting a superclass, instance extents, and whether a class is native-refcounted are all useful type API. De-underscore these functions and give them a consistent `swift[_objc]_class*` naming scheme.

Subject: [PATCH 0509/1732] Revert "Include access functions for the metadata
 and witness tables"

This reverts commit b1e3120a28f4530700d68d68aa30328d079b29ef.

Reverting because this patch uses WitnessTableBuilder::PI in NDEBUG code.
That field only exists when NDEBUG is not defined, but now NextCacheIndex, a
field that exists regardless, is being updated based on information from PI.

This problem means that Release builds do not work.

Subject: [PATCH 0512/1732] Runtime: Rename reportMissingMethod to
 deletedMethodError.

The runtime entry doesn't just report the error, unlike the other report* functions, it also does the crashing.

Reapplying independent of unrelated reverted patches.

Subject: [PATCH 0521/1732] [build-script] Do not determine build jobs in impl

Begins work on SR-237.

Rather than determining the number of jobs to use for `make` or
`dsymutil` from within build-script-impl, this change passed in those
values from above.

Furthermore, because we can determine the number of build jobs via a
builtin Python function, we figure out the number of jobs to use from
within `utils/build-script`. Now, by default, the same number of jobs
will be used to build this project as there are cores on the host
machine. Users may still specify a different number, as before, using
the `--jobs` option.

This introduces a behavioral change. Before, running
`utils/build-script` would run something like the following `cmake`
command:

```
cmake --build /build/Ninja-DebugAssert/llvm-macosx-x86_64 -- all
```

Notice the lack of jobs specified. The new default is something like
the following:

```
cmake --build /build/Ninja-DebugAssert/llvm-macosx-x86_64 -- -j8 all
```

Notice that the number of jobs is exlicitly passed to the command.

Subject: [PATCH 0537/1732] IRGen: Include resilient field offset globals in
 Objective-C ivar metadata

We don't actually care that the field offset is fixed in the
struct layout, only that it is not dependent.

This is NFC for now, until resilient class layout lands.

Subject: [PATCH 0542/1732] IRGen: Some field offset globals can be constant

It is questionable if emitting globals for constant offsets is of
any use; the only scenario where one could not compute the offset
directly in IRGen is if the class has a fixed-size layout inside
its own resilience domain, but has a non-fixed layout outside,
*and* we're doing direct stored property access.

Right now we don't plan on doing this, but it might come up in
the future with more exotic resilience domain configurations or
perhaps optimizations.

Subject: [PATCH 0543/1732] Runtime: Clean up logic for setting Objective-C
 name of generic classes

We're not currently doing it, but we will soon be able to use
swift_initializeSuperclass() for class layouts which are not
dependent on generic parameters. In this case, we still need
to set the Objective-C class name.

On the other hand, if we're doing resilient layout for a
non-generic class, we don't need to set the Objective-C class
name.

NFC since this isn't hooked up completely yet.

Subject: [PATCH 0546/1732] IRGen: Layout of root classes containing
 resiliently-sized fields

Now that all the machinery is in place, the ClassMetadataBuilder
can (more accurately) query the ClassLayout instead of trying to
re-derive whether the field offset vector is dependent, etc.

Apart from performing dynamic layout for resiliently-sized fields
in concrete classes, this also lets us *skip* dynamic layout
if we have a generic class without any dependent fields.

I haven't tested subclassing with resilient field layout yet, but
getting that working is the next step and should not be too much
work.

Also, swift_initClassMetadata_UniversalStrategy() only stores
the computed field offsets in the field offset globals when the
Objective-C runtime is available, because it gets the offset
pointers from the Objective-C class rodata. On Linux, we will
need to emit code to copy from the field offset vector into
field offset globals in IRGen. This is pretty easy, but I'll do
it in a follow-up patch so for now the new execution test is
XFAIL'd on Linux.

Subject: [PATCH 0554/1732] [python] Use PEP-0008 compliant code headers

Running the Python style guide checker
[`pep8`](https://pypi.python.org/pypi/pep8) on the Python code headers
in this repository results in the following error being emitted:

    $ pep8 utils/build-script
    utils/build-script:1:1: E265 block comment should start with '# '
    utils/build-script:3:1: E266 too many leading '#' for block comment
    utils/build-script:5:1: E266 too many leading '#' for block comment
    utils/build-script:6:1: E266 too many leading '#' for block comment
    utils/build-script:8:1: E266 too many leading '#' for block comment
    utils/build-script:9:1: E266 too many leading '#' for block comment
    utils/build-script:11:1: E265 block comment should start with '# '
    utils/build-script:11:80: E501 line too long (80 > 79 characters)

The problem is that the code header used in most Python files in the
repository:

1. Do not place a space in between `#` and the rest of the comment.
2. Contains some lines that just barely exceed the recommend length
   limit.

In addition, not all code headers in the repository follow the same
template.

This commit moves all Python code headers to the following template:

Subject: [PATCH 0557/1732] Extend fix-its for C-style for loops to include
 loop var "+= 1"
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Since the commit to deprecate “++” went through soon after the one to
deprecate C-style for loops, it’d be nice to auto-fix the for loops
even after previously changing ++ to += 1. So let’s do that.

From 9c3ccc98553ffdff92a3d2466e8ca0c912873182 Mon Sep 17 00:00:00 2001 From: Slava Pestov Date: Fri, 15 Jan 2016 17:12:03 -0800 Subject: [PATCH 1231/1732] Sema: Plumb through resiliently-accessed global variables My recent changes added "resiliently-sized" global variables, where a global in one module is defined to be of a type from another module, and the type's size is not known at compile time. This patch adds the other half of the equation: when accessing a global variable defined by another module, we want to use accessors since we want to resiliently change global variables from stored to computed and vice versa. The main complication here is that the synthesized accessors are not part of any IterableDeclContext, and require some special-casing in SILGen and Serialization. There might be simplifications possible here. For testing and because of how the resilience code works right now, I added the @_fixed_layout attribute to global variables. In the future, we probably will not give users a way to promise that a stored global variable will always remain stored; or perhaps we will hang this off of a different attribute, once we finalize the precise set of attributes exposed for resilience. There's probably some other stuff with lazy and observers I need to think about here; leaving that for later. --- include/swift/AST/Attr.def | 2 +- lib/AST/Decl.cpp | 8 +++- lib/SILGen/SILGen.cpp | 9 ++++ lib/Sema/CodeSynthesis.cpp | 10 +++-- lib/Sema/TypeCheckDecl.cpp | 25 ++++++++--- lib/Serialization/Serialization.cpp | 12 ++++++ test/Inputs/global_resilience.swift | 3 ++ test/Inputs/resilient_global.swift | 2 + test/SILGen/global_resilience.swift | 65 +++++++++++++++++++++++++++++ 9 files changed, 124 insertions(+), 12 deletions(-) create mode 100644 test/Inputs/global_resilience.swift create mode 100644 test/SILGen/global_resilience.swift diff --git a/include/swift/AST/Attr.def b/include/swift/AST/Attr.def index c4e48c7756be3..e87775cafa3ee 100644 --- a/include/swift/AST/Attr.def +++ b/include/swift/AST/Attr.def @@ -162,7 +162,7 @@ SIMPLE_DECL_ATTR(nonobjc, NonObjC, OnFunc | OnVar | OnSubscript | OnConstructor, 30) SIMPLE_DECL_ATTR(_fixed_layout, FixedLayout, - OnClass | OnStruct | OnEnum | UserInaccessible, 31) + OnVar | OnClass | OnStruct | OnEnum | UserInaccessible, 31) // Non-serialized attributes. diff --git a/lib/AST/Decl.cpp b/lib/AST/Decl.cpp index f296a43c72dd9..fc4fad6436fb5 100644 --- a/lib/AST/Decl.cpp +++ b/lib/AST/Decl.cpp @@ -1335,14 +1335,18 @@ bool AbstractStorageDecl::hasFixedLayout() const { if (getFormalAccess() != Accessibility::Public) return true; + // Check for an explicit @_fixed_layout attribute. + if (getAttrs().hasAttribute()) + return true; + // If we're in a nominal type, just query the type. auto nominal = getDeclContext()->isNominalTypeOrNominalTypeExtensionContext(); if (nominal) return nominal->hasFixedLayout(); - // FIXME: Must use resilient access patterns. + // Must use resilient access patterns. assert(getDeclContext()->isModuleScopeContext()); - return true; + return false; } diff --git a/lib/SILGen/SILGen.cpp b/lib/SILGen/SILGen.cpp index aed99a257f8dd..59efc6edce020 100644 --- a/lib/SILGen/SILGen.cpp +++ b/lib/SILGen/SILGen.cpp @@ -907,6 +907,15 @@ void SILGenModule::visitPatternBindingDecl(PatternBindingDecl *pd) { void SILGenModule::visitVarDecl(VarDecl *vd) { if (vd->hasStorage()) addGlobalVariable(vd); + + if (vd->getStorageKind() == AbstractStorageDecl::StoredWithTrivialAccessors) { + // If the global variable has storage, it might also have synthesized + // accessors.

Previously we would only ever look at the @_fixed_layout attribute on a type. If the flag was not specified, Sema would slap this attribute on every type that gets validated. This is wasteful for non-resilient builds, because there all types get the attribute. It was also apparently wrong, and I don't fully understand when Sema decides to validate which decls. It is much cleaner conceptually to just serialize this flag with the module, and check for its presence if the attribute was not found on a type. --- include/swift/AST/Module.h | 29 ++++++++++++------ include/swift/Basic/LangOptions.h | 4 --- include/swift/Frontend/FrontendOptions.h | 7 ++++- include/swift/Option/FrontendOptions.td | 6 ++-- include/swift/Sema/SourceLoader.h | 13 +++++--- include/swift/Serialization/ModuleFormat.h | 9 ++++-- include/swift/Serialization/Validation.h | 5 +++ lib/AST/Decl.cpp | 4 +-- lib/AST/Module.cpp | 9 +++--- lib/Frontend/CompilerInvocation.cpp | 8 +---- lib/Frontend/Frontend.cpp | 7 ++++- lib/Sema/SourceLoader.cpp | 2 ++ lib/Sema/TypeCheckDecl.cpp | 32 -------------------- lib/Serialization/ModuleFile.cpp | 3 ++ lib/Serialization/Serialization.cpp | 6 ++++ lib/Serialization/SerializedModuleLoader.cpp | 2 ++ test/Serialization/resilience.swift | 22 ++++++++++++++ test/attr/attr_fixed_layout.swift | 2 +- 18 files changed, 99 insertions(+), 71 deletions(-) create mode 100644 test/Serialization/resilience.swift diff --git a/include/swift/AST/Module.h b/include/swift/AST/Module.h index ec8b5cca8f074..d58ab8c63346c 100644 --- a/include/swift/AST/Module.h +++ b/include/swift/AST/Module.h @@ -267,13 +267,14 @@ class ModuleDecl : public TypeDecl, public DeclContext { /// \see EntryPointInfoTy EntryPointInfoTy EntryPointInfo;

This generic signature is only used to answer questions about the abstraction pattern's own formal type, and not with the substituted type. So only put type lowering cache entries in the dependent cache if they contain interface types in the substituted type. Otherwise, if only the abstraction pattern has interface types in it, the entry can live in the independent cache, allowing it to be looked up without a pushGenericContext() / popGenericContext() call. For correctness, we now have to store the generic signature in the type key as well. Subsequent changes should reduce the size of the cache, by lowering fewer archetypes.

And use project_box to get to the address value. SILGen now generates a project_box for each alloc_box. And IRGen re-uses the address value from the alloc_box if the operand of project_box is an alloc_box. This lets the generated code be the same as before. Other than that most changes of this (quite large) commit are straightforward. --- docs/SIL.rst | 27 +- include/swift/SIL/SILInstruction.h | 9 +- include/swift/SILOptimizer/Utils/Local.h | 5 + include/swift/Serialization/ModuleFormat.h | 2 +- lib/IRGen/IRGenSIL.cpp | 70 +- lib/SIL/SILInstructions.cpp | 16 +- lib/SIL/Verifier.cpp | 14 +- lib/SILGen/SILGenApply.cpp | 6 +- lib/SILGen/SILGenDecl.cpp | 5 +- lib/SILGen/SILGenFunction.cpp | 2 +- .../ARC/RCStateTransitionVisitors.cpp | 7 +- .../Analysis/SimplifyInstruction.cpp | 11 - lib/SILOptimizer/IPO/CapturePromotion.cpp | 60 +- .../LoopTransforms/COWArrayOpt.cpp | 3 +- .../Mandatory/DIMemoryUseCollector.cpp | 46 +- .../Mandatory/DIMemoryUseCollector.h | 14 +- .../Mandatory/DefiniteInitialization.cpp | 7 +- .../Mandatory/MandatoryInlining.cpp | 50 +- .../Mandatory/PredictableMemOpt.cpp | 4 +- .../Transforms/AllocBoxToStack.cpp | 46 +- lib/SILOptimizer/Utils/Local.cpp | 14 + test/IRGen/dynamic_lookup.sil | 20 +- test/IRGen/partial_apply.sil | 3 +- test/IRGen/typed_boxes.sil | 89 +- test/SIL/Parser/apply_with_substitution.sil | 7 +- test/SIL/Parser/basic.sil | 164 ++- test/SIL/Parser/bound_generic.sil | 7 +- .../Parser/generic_signature_with_depth.swift | 2 +- test/SIL/Parser/global_init_attribute.sil | 3 +- test/SIL/Parser/overloaded_member.sil | 20 +- test/SIL/Parser/typed_boxes.sil | 10 +- test/SILGen/address_only_types.swift | 30 +- test/SILGen/addressors.swift | 5 +- test/SILGen/boxed_existentials.swift | 16 +- test/SILGen/builtins.swift | 101 +- test/SILGen/capture_inout.swift | 2 +- test/SILGen/class_bound_protocols.swift | 20 +- test/SILGen/closures.swift | 50 +- test/SILGen/complete_object_init.swift | 5 +- test/SILGen/copy_lvalue_peepholes.swift | 14 +- test/SILGen/decls.swift | 46 +- test/SILGen/default_constructor.swift | 3 +- test/SILGen/dynamic_lookup.swift | 57 +- test/SILGen/dynamic_self.swift | 5 +- test/SILGen/errors.swift | 45 +- test/SILGen/expressions.swift | 20 +- test/SILGen/foreign_errors.swift | 3 +- test/SILGen/functions.swift | 35 +- test/SILGen/guaranteed_closure_context.swift | 4 +- test/SILGen/guaranteed_self.swift | 17 +- test/SILGen/if_expr.swift | 6 +- .../implicitly_unwrapped_optional.swift | 7 +- test/SILGen/indirect_enum.swift | 29 +- test/SILGen/init_ref_delegation.swift | 25 +- test/SILGen/let_decls.swift | 14 +- test/SILGen/lifetime.swift | 59 +- test/SILGen/metatype_abstraction.swift | 4 +- test/SILGen/objc_init_ref_delegation.swift | 5 +- test/SILGen/objc_ownership_conventions.swift | 4 +- test/SILGen/objc_protocols.swift | 7 +- test/SILGen/objc_thunks.swift | 10 +- test/SILGen/optional-cast.swift | 28 +- test/SILGen/optional.swift | 18 +- test/SILGen/optional_lvalue.swift | 9 +- test/SILGen/pointer_conversion.swift | 10 +- test/SILGen/properties.swift | 78 +- test/SILGen/property_abstraction.swift | 3 +- test/SILGen/protocol_class_refinement.swift | 22 +- test/SILGen/protocol_extensions.swift | 31 +- test/SILGen/protocol_optional.swift | 18 +- test/SILGen/protocols.swift | 22 +- test/SILGen/reabstract_lvalue.swift | 5 +- test/SILGen/sil_locations.swift | 4 +- test/SILGen/statements.swift | 7 +- test/SILGen/struct_resilience.swift | 10 +- test/SILGen/super_init_refcounting.swift | 9 +- test/SILGen/tuples.swift | 28 +- test/SILGen/types.swift | 8 +- test/SILGen/unowned.swift | 15 +- test/SILGen/weak.swift | 14 +- test/SILOptimizer/allocbox_to_stack.sil | 163 ++- test/SILOptimizer/arcsequenceopts.sil | 50 +- test/SILOptimizer/capture_promotion.sil | 56 +- .../capture_promotion_reachability.sil | 150 +- test/SILOptimizer/closure_specialize.sil | 25 +- test/SILOptimizer/cse.sil | 7 +- test/SILOptimizer/dead_store_elim.sil | 5 +- test/SILOptimizer/definite_init.sil | 134 +- test/SILOptimizer/definite_init_crashes.sil | 23 +- test/SILOptimizer/diagnose_unreachable.sil | 7 +- test/SILOptimizer/escape_analysis.sil | 122 +- .../globalredundantloadelimination.sil | 5 +- test/SILOptimizer/looprotate.sil | 3 +- test/SILOptimizer/lslocation_expansion.sil | 5 +- test/SILOptimizer/lslocation_reduction.sil | 5 +- test/SILOptimizer/mandatory_inlining.sil | 199 +-- test/SILOptimizer/mem2reg.sil | 14 +- test/SILOptimizer/predictable_memopt.sil | 68 +- .../SILOptimizer/redundantloadelimination.sil | 7 +- test/SILOptimizer/side-effect.sil | 5 +- test/SILOptimizer/sil_combine.sil | 21 +- test/SILOptimizer/sil_locations.sil | 45 +- test/SILOptimizer/simplify_cfg.sil | 7 +- test/SILOptimizer/specialize.sil | 15 +- ...tatypes_with_nondefault_representation.sil | 15 +- test/SILOptimizer/split_critical_edges.sil | 10 +- test/SILOptimizer/typed-access-tb-aa.sil | 1266 +++++++++-------- test/Serialization/Inputs/def_basic.sil | 154 +- test/sil-extract/basic.sil | 10 +- 109 files changed, 2427 insertions(+), 1899 deletions(-) diff --git a/docs/SIL.rst b/docs/SIL.rst index 0b1232fc71137..cc312f1038aa3 100644 --- a/docs/SIL.rst +++ b/docs/SIL.rst @@ -715,13 +715,13 @@ In SIL, a single instruction may produce multiple values.

This change is needed for the next update to ToT LLVM. It can be put into place now without breaking anything so I am committing it now. The churn upstream on ilist_node is neccessary to remove undefined behavior. Rather than updating the different ilist_node patches for the hacky change required to not use iterators, just use iterators and keep everything as ilist_nodes. Upstream they want to eventually do this, so it makes sense for us to just do it now.

1334/1732] Sema: Fix checkMutating() for stored properties that had accessors synthesized for them already Otherwise, a struct's static property cannot witness two different protocol requirements,

A more principled fix would change the SILGen logic to use a materializeForSet if it would have been synthesized anyway, asserting that it was synthesized in that case.

Fix that by replacing the setter->isMutating() call with a direct computation of the expected result.

A better fix would be to first address the issue where @_transparent function bodies are not serialized in some cases, and then only emit synthesized accessors as needed, in the original version of this patch. To fix the duplicate symbol issues, we would emit the synthesized accessors with shared linkage, which would always work once serialized bodies were available. For resilient structs of course, we'll always need to emit accessors anyway. --- lib/Sema/CodeSynthesis.cpp | 31 +++++++++++++------ test/IRGen/class_bounded_generics.swift | 2 +-

And use the new project_existential_box to get to the address value. SILGen now generates a project_existential_box for each alloc_existential_box. And IRGen re-uses the address value from the alloc_existential_box if the operand of project_existential_box is an alloc_existential_box. This lets the generated code be the same as before. --- docs/SIL.rst | 23 +++++--------- include/swift/SIL/SILBuilder.h | 4 +-- include/swift/SIL/SILCloner.h | 1 - include/swift/SIL/SILInstruction.h | 12 ++----- lib/IRGen/GenExistential.cpp | 14 ++++----- lib/IRGen/GenExistential.h | 4 +-- lib/IRGen/IRGenSIL.cpp | 26 +++++++++------- lib/Parse/ParseSIL.cpp | 11 +------ lib/SIL/SILInstructions.cpp | 19 ++---------- lib/SIL/Verifier.cpp | 31 +++++++------------ lib/SILGen/SILGenConvert.cpp | 9 +++--- lib/SILGen/SILGenFunction.cpp | 2 -- lib/SILGen/SILGenFunction.h | 1 - .../SILCombiner/SILCombinerMiscVisitors.cpp | 23 +++++++++++--- lib/Serialization/DeserializeSIL.cpp | 1 - test/IRGen/boxed_existential.sil | 10 +++--- test/SIL/Parser/basic.sil | 22 ++++++------- test/SILGen/boxed_existentials.swift | 15 +++++---- test/SILGen/errors.swift | 10 +++--- test/SILGen/existential_erasure.swift | 7 +++-- test/SILGen/toplevel_errors.swift | 7 +++-- test/SILOptimizer/escape_analysis.sil | 21 ++++++++----- test/SILOptimizer/sil_combine.sil | 7 +++-- test/Serialization/Inputs/def_basic.sil | 22 ++++++------- 24 files changed, 137 insertions(+), 165 deletions(-) diff --git a/docs/SIL.rst b/docs/SIL.rst index 5ce89eb428c20..0127a7253b00e 100644 --- a/docs/SIL.rst +++ b/docs/SIL.rst @@ -703,7 +703,7 @@ Values and Operands sil-identifier ::= [A-Za-z_0-9]+ sil-value-name ::= '%' sil-identifier - sil-value ::= sil-value-name ('#' [0-9]+)? + sil-value ::= sil-value-name sil-value ::= 'undef' sil-operand ::= sil-value ':' sil-type @@ -711,17 +711,6 @@ SIL values are introduced with the ``%`` sigil and named by an alphanumeric identifier, which references the instruction or basic block argument that produces the value.

Decrease the size of nominal type descriptors and make them true-const by relative-addressing the other metadata they need to reference, which should all be included in the same image as the descriptor itself. Relative-referencing string constants exposes a bug in the Apple linker, which crashes when resolving relative relocations to coalesceable symbols (rdar://problem/22674524); work around this for now by revoking the `unnamed_addr`-ness of string constants that we take relative references to. (I haven't tested whether GNU ld or gold also have this problem on Linux; it may be possible to conditionalize the workaround to only apply to Darwin targets for now.) --- include/swift/Basic/RelativePointer.h | 75 +++++++++-- include/swift/Runtime/Metadata.h | 36 +++-- lib/IRGen/GenDecl.cpp | 25 +++- lib/IRGen/GenEnum.cpp | 5 +- lib/IRGen/GenMeta.cpp | 125 ++++++++++++++---- lib/IRGen/IRGenModule.h | 10 +- stdlib/public/runtime/Leaks.mm | 2 +- stdlib/public/runtime/Metadata.cpp | 4 +- stdlib/public/runtime/MetadataLookup.cpp | 2 +- stdlib/public/runtime/ProtocolConformance.cpp | 2 +- test/IRGen/enum.sil | 11 +- test/IRGen/field_type_vectors.sil | 10 +- test/IRGen/generic_classes.sil | 24 ++-- test/IRGen/generic_structs.sil | 28 ++-- test/IRGen/objc_attr_NSManaged.sil | 2 +- test/IRGen/vtable.sil | 4 +- 16 files changed, 260 insertions(+), 105 deletions(-) diff --git a/include/swift/Basic/RelativePointer.h b/include/swift/Basic/RelativePointer.h index c5c084185a55a..a6c8ad4e66887 100644 --- a/include/swift/Basic/RelativePointer.h +++ b/include/swift/Basic/RelativePointer.h @@ -26,7 +26,7 @@ namespace swift { /// A relative reference to an object stored in memory.

This means that one day -our phones will have hundreds of shared libraries (written in swift) loaded at -the same time.

The string table (linkedit section in -Mach-O) is loaded into memory (as shared copy-on-write). In a world where every -single process uses multiple swift libraries reducing the size of this section -is very beneficial for memory usage, load time, disk usage, etc.. - -On-disk and over-the-air compression can improve things, but these techniques -are insufficient because generic compression is not as effective as domain -specific compression, and they do not address the problem of in-memory tables. - - -Character Set -------------- -The decision on a character set to be used by the compression scheme is -independent of the algorithms that are used for compression. The more characters -that we can use the more efficient the encoding would be. The Base64 encoding -scheme uses 64 characters and has a 75% efficiency compared to unrestricted -8-bit ascii. Base64 uses 6 bits to encode 8 bits of ascii. - -The current implementation uses the character set A-Z, a-z, 0-9 and "_", which -are the legal identifier characters in C. We need to use only printable -characters if we want tools such as nm to be able to work well. It is possible -to extend the character set to more printable characters but this will make SIL -(that uses these names freely) less usable. For example, names should probable -not contain the character , but is probably okay. - -Symbol Compression ------------------- - -This section describes the Swift symbol compression. In Swift we compress each -symbol individually as part of the mangling phase. The compression phase has two -steps: - -1. Dictionary based compression (similar to Lempel-Ziv) -2. Variable length compression (Huffman Coding) - -The swift Mangler and Demangler are responsible for compressing and -decompressing the symbols, and this process is transparent to the debugger. The -nm command line tool prints the compressed name, and swift-demangle is -responsible for decompressing and demangling the name properly. - -Together, the Dictionary based compression and the Variable length compression -are able to compress the size of the string section down to 50% (half of the -original size). - -Dictionary-based compression ----------------------------- - -This section describes the dictionary based compression. This compression phase -reduces the string table section by about 40%. Unlike Lempel-Ziv, the -dictionary-based compression algorithm that we use here can't make use of string -repetitions to compress the string because the input strings are too short. The -obvious alternative is to use "prior knowledge". We know what are the common -sub-strings that are used in Swift names. Some of the most common substrings in -Swift mangled names are: - - "S_S_S_S", "ollectio", "Type", "Index", "erator", "7Element", and "able". - -We can use this prior knowledge to compress our mangling! - -In our compression scheme we compress this string: - -__TTSg5VSS13CharacterView - -Into a string that contains references to some global table that is available to the compressor and decompressor. - -__TTSg513View - -Commonly used strings are encoded as references to global tables. The reference -needs to be encoded as part of the name. We need to have some escape character -and use that character to encode the reference. In our encoding scheme we have two -escape characters. - -The first escape character records an index using a single character. This allows us to encode -the top 63 frequent substrings in our dictionary using two characters (escape + index). - -The second escape character encodes a two-character reference that can access 63 x 63 entries in the table. -Less common substrings can be encoded using this three character sequence (escape + index0 + index1). - -One interesting bit of information is that the character "Y" is only used 4 -times in the entire standard library! The letter J, and a few other letters are -also not used very frequently. We use Y and J as escape characters. - -The dictionary-based encoding uses the following rules: - -1. We use two escape characters that are not frequently used in names (Y and Z). -These characters are escape character and cannot be used as part of the text -without escaping. "Y" is encoded as "YY", and "Z" would be encoded as "YZ". - -2. The most commonly used sub-strings (calculated as length of substring times -number of occurrences) is encoded with a single escape character and a -single index character. The table of highly repetitive substrings can only -contain 61 entries (a-zA-Z0-9_, minus two escape characters). - -A reference to the very frequent substrings is encoded as "Yx", where x is the -character that is translated into a numeric index. This is two chars per -substring. - -3. The less frequently used substrings are encoded as three-character sequence. -"Zxx", where xx is the numeric index in the large table (that can hold 61*61 -substrings). - -It is obvious how to reverse this compression using the same string table used -to compress the names. - -With this encoding scheme the name -"__TwxxV14StdlibUnittest24MinimalForwardCollection" becomes -"__TwxxJ1QYrt24J6wJ5KY9on" and the name "__TMPVs15ContiguousArray" becomes -"__TMPJOSJ6lJ8G". - -Notice that the "_T" prefix is kept and should not be compressed because it -differentiates between swift symbols and non-swift symbols. - -These are two related works on dictionary-based compression: - -"Text compression using a 4 bit coding scheme" by J Pike. -"A universal algorithm for sequential data compression (1977)" by Jacob Ziv , Abraham Lempel - -Variable Length encoding ------------------------- - -The variable length encoding that we use is pretty standard. We use Huffman -encoding to encode frequently used characters with few bits. One interesting -aspect of the problem is that we use a character set that is not a power of two. -To encode a bit stream in a character set that is now a power of two we need to -represent the whole name as a big number and perform the operation of div-modulo -for each character we encode, where the div-modulo value is the number of -characters we use to encode the string. - -Strings are encoded into numbers in reverse (end to start) to make the -decompression faster by allowing strings to be appended and not prepended. - -Implementation --------------- - -This section describes the implementation of the symbol compression. Both the -dictionary-based compression and the variable length compression are implemented -in a similar way. An external program is used to scan lots of data that -represents the kind of strings that are likely to be common, and generate header -files that contain information that is used by the compression routines. - -The dictionary-based compression generates an H file that contains information -about the escape characters used, the list of words in the codebook (this is the -list of substrings), a list of lengths for each substrings (to accelerate length -calculations). - -Our codebook contains about 3000 entries. In order to compress a word we need to -search the whole codebook, for every character in the string. This is slow -inefficient. Instead, the external program is generating a C program that -implements a search in a Trie-like data structure. The auto-generate search -routine exposes an API that returns the index of the matched word given a string -(the original uncompressed symbol) and length until the end of the string. - -The Huffman coding uses a similar technique. An external program auto-generates -routines that encode a sequence of strings into a number, or extract a number from -a sequence of strings. - -The external programs CBCGen.py and HuffGen.py generate the header files -HuffTables.h and CBC.h. - -Generating the compiler header files ------------------------------------- - -This section describes how to generate the compression tables using a training -set and create the header files (that are currently checked in as part of the -compiler). We generate the compression codebook and the Huffman tables using -data that we think represent the kind of symbol names people use in Swift. It is -important to select training data that is representitive or else the compression -will be less effective. - -Step1: Generate a list of mangled names from swift dylibs. This is done using -the "nm" command: "nm libSwiftCode.dylib > names.txt". Next, remove the prefix -that nm is adding (stuff like "U", "T" and "t" and addresses of symbols in the -dylib) and keep one name per line. - -Once we enable compression in our manglers you will need to decompress these -names using the utility swift-compress: -"cat compressed_names.txt | swift-compress -decompress > names.txt" - -Step2: Run "CBCGen.py file1.txt file2.txt file3.txt > CBC.h" -This will create the CBC header file. - -Step3: Recompile swift-compress and use it to compress names without applying -huffman encoding: "cat names.txt | swift-compress -cbc-only > names.txt.cbc" -This will create a file with names that are only compressed with the CBC -encoder, which is the input of our huffman encoder. - -Step4: Run HuffGen on the cbc-compressed file to generate the huffman encoding -tables: "./HuffGen.py names.txt.cbc > HuffTables.h" - -Error handling --------------- - -The compression routines only handle characters that are in the list of valid -characters. It is possible to compress every string that uses the valid -character set. However, now all incoming strings are legal. For example the -string "Y" is illegal because "Y" is an escape character and the decoded expects -another character to follow the escape character. - -There are a few users that will use the compression routines: The -mangler/demangler/remangler (in the compiler and debugger), the migration tool, -the unittests, etc. The current error handling strategy is to have asserts in -the compiler (in release builds). In addition to asserts the compiler handles -the decoding of malformed strings by returning an empty string. This is not -ideal and the compression routines should return a boolean flag that says if the -decompression succeeded. - -Migration plan --------------- - -Once we finalize the encoding scheme we need to update many places in the compiler. This includes testcases -and places in the compiler where we've hard coded names of functions. -The swift-compress utility can be used to compress and decompress mangled names that appear in text.. -Just like swift-demangle this utility can replace strings and preserve the text around the mangled name. -This tool can help us in upgrading test files. - diff --git a/include/swift/ABI/Compression.h b/include/swift/ABI/Compression.h deleted file mode 100644 index 83152a3667b96..0000000000000 --- a/include/swift/ABI/Compression.h +++ /dev/null @@ -1,53 +0,0 @@ -//===--- Compression.h - Defines the compression interface ------*- C++ -*-===// -// -// This source file is part of the Swift.org open source project -// -// Copyright (c) 2014 - 2016 Apple Inc. and the Swift project authors -// Licensed under Apache License v2.0 with Runtime Library Exception -// -// See http://swift.org/LICENSE.txt for license information -// See http://swift.org/CONTRIBUTORS.txt for the list of Swift project authors -// -//===----------------------------------------------------------------------===// -#ifndef SWIFT_ABI_COMPRESSION_H -#define SWIFT_ABI_COMPRESSION_H - -#include "llvm/ADT/APInt.h" -#include - -namespace swift { -namespace Compress { - -/// Compress a string using the swift codebook compression. -/// Returns a new compressed string from \p In. -std::string DecodeCBCString(llvm::StringRef In); - -/// Decompress a string using the swift codebook compression. -/// Returns a new decompressed string from \p In. -std::string EncodeCBCString(llvm::StringRef In); - -/// Character encoding kind: -/// Variable - huffman encoding using variable length characters. -/// Fixed - simple fixed length characters. -enum class EncodingKind { Variable, Fixed }; - -/// Convert the string \p In into a number using a fixed length or variable -/// length encoding. -llvm::APInt EncodeStringAsNumber(llvm::StringRef In, EncodingKind Kind); - -/// Convert the number \p In into a string using a fixed length or variable -/// length encoding. -std::string DecodeStringFromNumber(const llvm::APInt &In, EncodingKind Kind); - -/// Compress the string \p In with CBC and variable length encoding. -/// On error return an empty string. -std::string CompressName(llvm::StringRef In); - -/// Decompress the string \p, which is compressed using the swift name -/// compression.

Basic implementatation of SE-0021, naming functions with argument labels. Handle parsing of compound function names in various unqualified-identifier productions, updating the AST representation of various expressions from Identifiers to DeclNames. The result doesn't capture all of the source locations we want; more on that later. As part of this, remove the parsing code for the "selector-style" method names, since we now have a replacement. The feature was never publicized and doesn't make sense in Swift, so zap it outright. --- include/swift/AST/DiagnosticsParse.def | 3 + include/swift/AST/DiagnosticsSema.def | 17 +- include/swift/AST/Expr.h | 22 +-- include/swift/AST/Identifier.h | 6 +- include/swift/Parse/Parser.h | 25 ++- lib/IDE/SyntaxModel.cpp | 2 +- lib/Parse/ParseExpr.cpp | 216 ++++++++++++++--------- lib/Parse/ParseStmt.cpp | 11 +- lib/Sema/CSApply.cpp | 2 +- lib/Sema/CSDiag.cpp | 10 +- lib/Sema/TypeCheckConstraints.cpp | 8 +- lib/Sema/TypeCheckPattern.cpp | 18 +- lib/Sema/TypeChecker.cpp | 2 +- test/ClangModules/objc_parse.swift | 11 +- test/Constraints/fixes.swift | 2 +- test/TypeCoercion/overload_noncall.swift | 2 +- test/decl/ext/protocol.swift | 4 +- test/expr/postfix/dot/selector.swift | 46 ----- test/expr/primary/unqualified_name.swift | 56 ++++++ 19 files changed, 279 insertions(+), 184 deletions(-) delete mode 100644 test/expr/postfix/dot/selector.swift create mode 100644 test/expr/primary/unqualified_name.swift diff --git a/include/swift/AST/DiagnosticsParse.def b/include/swift/AST/DiagnosticsParse.def index f487a369a8d73..96db8277cdeea 100644 --- a/include/swift/AST/DiagnosticsParse.def +++ b/include/swift/AST/DiagnosticsParse.def @@ -953,6 +953,9 @@ ERROR(availability_query_outside_if_stmt_guard, none, "#available may only be used as condition of an 'if', 'guard'" " or 'while' statement", ()) +ERROR(empty_arg_label_underscore, none, + "an empty argument label is spelled with '_'", ()) + ERROR(expected_identifier_after_dot_expr,none, "expected identifier after '.' expression", ()) diff --git a/include/swift/AST/DiagnosticsSema.def b/include/swift/AST/DiagnosticsSema.def index 190bf3418987b..c442d31ca5377 100644 --- a/include/swift/AST/DiagnosticsSema.def +++ b/include/swift/AST/DiagnosticsSema.def @@ -55,7 +55,7 @@ NOTE(while_converting_subscript_index,none, //------------------------------------------------------------------------------ ERROR(ambiguous_member_overload_set,none, - "ambiguous reference to member '%0'", (StringRef)) + "ambiguous reference to member %0", (DeclName)) ERROR(ambiguous_subscript,none, "ambiguous subscript with base type %0 and index type %1", @@ -76,9 +76,9 @@ NOTE(did_you_mean_raw_type,none, "did you mean to specify a raw type on the enum declaration?", ()) ERROR(expected_argument_in_contextual_member,none, - "contextual member %0 expects argument of type %1", (Identifier, Type)) + "contextual member %0 expects argument of type %1", (DeclName, Type)) ERROR(unexpected_argument_in_contextual_member,none, - "contextual member %0 has no associated value", (Identifier)) + "contextual member %0 has no associated value", (DeclName)) ERROR(could_not_use_value_member,none, "member %1 cannot be used on value of type %0", (Type, DeclName)) @@ -443,7 +443,7 @@ ERROR(unspaced_unary_operator,none, ERROR(use_unresolved_identifier,none, - "use of unresolved %select{identifier|operator}1 %0", (Identifier, bool)) + "use of unresolved %select{identifier|operator}1 %0", (DeclName, bool)) ERROR(use_undeclared_type,none, "use of undeclared type %0", (Identifier)) ERROR(use_undeclared_type_did_you_mean,none, @@ -470,7 +470,7 @@ ERROR(use_non_type_value,none, NOTE(use_non_type_value_prev,none, "%0 declared here", (Identifier)) ERROR(use_local_before_declaration,none, - "use of local variable %0 before its declaration", (Identifier)) + "use of local variable %0 before its declaration", (DeclName)) ERROR(unsupported_existential_type,none, "protocol %0 can only be used as a generic constraint because it has " "Self or associated type requirements", (Identifier)) @@ -647,11 +647,10 @@ ERROR(argument_out_of_order_named_unnamed,none, ERROR(instance_member_use_on_type,none, "use of instance member %1 on type %0;

I think the right idea here is to weakly reference conformance tables where the deployment target is lower than the availability of the conformance. The second two are XFAIL'd until protocol conformance tables can reference resilient types from other modules. This requires emitting indirect metadata symbols, since the client doesn't know if the resilient type's metadata is direct or a template, and the conformance table cannot use the metadata accessor either. These tests will also become important if we decide to revisit synthesized accessors, and make them lazy again for structs. --- ...struct_fixed_layout_add_conformance.swift} | 6 +- ...ruct_fixed_layout_remove_conformance.swift | 28 ++++++ .../struct_resilient_add_conformance.swift | 40 +++++++++ .../struct_resilient_remove_conformance.swift | 28 ++++++ .../test_struct_add_remove_conformances.swift | 78 ----------------- ..._struct_fixed_layout_add_conformance.swift | 81 ++++++++++++++++++ ...ruct_fixed_layout_remove_conformance.swift | 64 ++++++++++++++ ...est_struct_resilient_add_conformance.swift | 85 +++++++++++++++++++ ..._struct_resilient_remove_conformance.swift | 68 +++++++++++++++ 9 files changed, 397 insertions(+), 81 deletions(-) rename validation-test/Evolution/Inputs/{struct_add_remove_conformances.swift => struct_fixed_layout_add_conformance.swift} (75%) create mode 100644 validation-test/Evolution/Inputs/struct_fixed_layout_remove_conformance.swift create mode 100644 validation-test/Evolution/Inputs/struct_resilient_add_conformance.swift create mode 100644 validation-test/Evolution/Inputs/struct_resilient_remove_conformance.swift delete mode 100644 validation-test/Evolution/test_struct_add_remove_conformances.swift create mode 100644 validation-test/Evolution/test_struct_fixed_layout_add_conformance.swift create mode 100644 validation-test/Evolution/test_struct_fixed_layout_remove_conformance.swift create mode 100644 validation-test/Evolution/test_struct_resilient_add_conformance.swift create mode 100644 validation-test/Evolution/test_struct_resilient_remove_conformance.swift diff --git a/validation-test/Evolution/Inputs/struct_add_remove_conformances.swift b/validation-test/Evolution/Inputs/struct_fixed_layout_add_conformance.swift similarity index 75% rename from validation-test/Evolution/Inputs/struct_add_remove_conformances.swift rename to validation-test/Evolution/Inputs/struct_fixed_layout_add_conformance.swift index 77a785206cd95..febca9a3c8d13 100644 --- a/validation-test/Evolution/Inputs/struct_add_remove_conformances.swift +++ b/validation-test/Evolution/Inputs/struct_fixed_layout_add_conformance.swift @@ -7,7 +7,7 @@ public func getVersion() -> Int { #endif } -@_fixed_layout public struct AddRemoveConformance { +@_fixed_layout public struct AddConformance { public init() { x = 0 y = 0 @@ -35,6 +35,6 @@ public protocol Point3DLike { } #if AFTER -extension AddRemoveConformance : PointLike {} -extension AddRemoveConformance : Point3DLike {} +extension AddConformance : PointLike {} +extension AddConformance : Point3DLike {} #endif diff --git a/validation-test/Evolution/Inputs/struct_fixed_layout_remove_conformance.swift b/validation-test/Evolution/Inputs/struct_fixed_layout_remove_conformance.swift new file mode 100644 index 0000000000000..bed0061e3fc35 --- /dev/null +++ b/validation-test/Evolution/Inputs/struct_fixed_layout_remove_conformance.swift @@ -0,0 +1,28 @@ + +@_fixed_layout public struct RemoveConformance { + public init() { + x = 0 + y = 0 + } + + public var x: Int + public var y: Int + + public var z: Int { + get { return x + y } + set { + x = newValue / 2 + y = newValue -

We usually want to use 32-bit offsets, since we use them to reference other objects within the same small-code-model image. However, for data structures that are both compiler-generated and runtime-allocated, we may want to save the relocation in compile time, but need a full-width offset to be able to relatively reference things from the heap.

This is needed if we compile StdlibUnittest with -sil-serialize-all So far I added the imports only in files which needed them. But this may change, depending on the optimizer (inlining). Adding them in all files doesn't harm and avoids confusion if someone makes an unrelated change which would result in such a linker error. --- test/1_stdlib/BoolBridge.swift | 8 ++++++++ test/1_stdlib/Builtins.swift | 8 ++++++++ test/1_stdlib/CollectionDiagnostics.swift | 8 ++++++++ test/1_stdlib/DarwinAPI.swift | 9 +++++++++ test/1_stdlib/DictionaryLiteral.swift | 8 ++++++++ test/1_stdlib/Dispatch.swift | 8 ++++++++ test/1_stdlib/ErrorTypeBridging.swift | 9 +++++++++ test/1_stdlib/ManagedBuffer.swift | 9 +++++++++ test/1_stdlib/NSArrayAPI.swift | 9 +++++++++ test/1_stdlib/NSDictionary.swift | 9 +++++++++ test/1_stdlib/NSEnumeratorAPI.swift | 9 +++++++++ test/1_stdlib/NSSetAPI.swift | 9 +++++++++ test/1_stdlib/NSStringAPI.swift | 9 +++++++++ test/1_stdlib/NSValueBridging.swift | 9 +++++++++ test/1_stdlib/RuntimeObjC.swift | 9 +++++++++ test/1_stdlib/SceneKit.swift | 9 +++++++++ test/1_stdlib/Unicode.swift | 8 ++++++++ test/Interpreter/availability_weak_linking.swift | 8 ++++++++ test/Interpreter/class_resilience.swift | 9 +++++++++ test/Interpreter/enum_errortype.swift | 8 ++++++++ test/Interpreter/enum_resilience.swift | 9 +++++++++ test/Interpreter/global_resilience.swift | 9 +++++++++ test/Interpreter/struct_resilience.swift | 9 +++++++++ test/Prototypes/CollectionTransformers.swift | 8 ++++++++ validation-test/stdlib/CoreMedia.swift | 9 +++++++++ validation-test/stdlib/CoreMediaOverlay.swift | 9 +++++++++ validation-test/stdlib/Dictionary.swift | 9 +++++++++ validation-test/stdlib/GameplayKit.swift | 9 +++++++++ validation-test/stdlib/Glibc.swift | 9 +++++++++ validation-test/stdlib/ObjectiveC.swift | 8 ++++++++ validation-test/stdlib/OpenCLSDKOverlay.swift | 9 +++++++++ validation-test/stdlib/SceneKit.swift | 9 +++++++++ validation-test/stdlib/Set.swift | 9 +++++++++ validation-test/stdlib/StdlibUnittestFailure.swift | 8 ++++++++ validation-test/stdlib/StdlibUnittestMisc.swift | 8 ++++++++ .../stdlib/StdlibUnittestStaticAssertions.swift | 8 ++++++++ validation-test/stdlib/Unicode.swift | 9 +++++++++ validation-test/stdlib/UnicodeUTFEncoders.swift | 9 +++++++++ validation-test/stdlib/WatchKit.swift | 9 +++++++++ validation-test/stdlib/XCTest.swift | 9 +++++++++ 40 files changed, 347 insertions(+) diff --git a/test/1_stdlib/BoolBridge.swift b/test/1_stdlib/BoolBridge.swift index ce45df3c205a2..7b91cbb573db7 100644 --- a/test/1_stdlib/BoolBridge.swift +++ b/test/1_stdlib/BoolBridge.swift @@ -5,6 +5,14 @@ import Foundation import StdlibUnittest +// Also import modules which are used by StdlibUnittest internally.

9f95f66f6e8c80b4f69c44b9a34281debcae45af Mon Sep 17 00:00:00 2001 From: Joe Groff Date: Thu, 21 Jan 2016 10:57:57 -0800 Subject: [PATCH 1411/1732] Avoid UB in RelativePointer on 32-bit platforms. We really want to apply offsets using wrapping (unsigned) arithmetic, albeit with sign extension. This is significant on 32-bit platforms, where "far" addresses could be more than 2GB apart, but still relative-referenced using 32-bit signed values, and offset addition could end up wrapping around. Factor the logic to add an offset to a pointer out into a function that performs the sacred casting dance to appease the UB gods. --- include/swift/Basic/RelativePointer.h | 50 ++++++++++++++++++--------- 1 file changed, 34 insertions(+), 16 deletions(-) diff --git a/include/swift/Basic/RelativePointer.h b/include/swift/Basic/RelativePointer.h index cf1820c6e59b6..13e23efdf6555 100644 --- a/include/swift/Basic/RelativePointer.h +++ b/include/swift/Basic/RelativePointer.h @@ -23,16 +23,41 @@ namespace swift { +namespace detail { + +/// Apply a relative offset to a base pointer.

For now, libdispatch is not built by default (user must enable via command line argument). Integration of testing is functional, but should be improved in a later pull request. The basic autotools based test harness does not give the nice high-level progress output as the rest of the test suite.

From 34a4075116fe6c73b93c9662a6bd80929f4067b6 Mon Sep 17 00:00:00 2001 From: Slava Pestov Date: Mon, 18 Jan 2016 01:05:15 -0800 Subject: [PATCH 1418/1732] IRGen: Implement resilient enum case numbering Recent changes added support for resiliently-sized enums, and enums resilient to changes in implementation strategy. This patch adds resilient case numbering, fixing the problem where adding new payload cases would break existing code by changing the numbering of no-payload cases. The problem is that internally, enum cases are numbered with payload cases coming first, followed by no-payload cases. While each list is itself in declaration order, with new additions coming at the end, we need to partition it to give us a fast runtime test for "is this a payload or no-payload case index." The resilient numbering strategy used here is that the getEnumTag and destructiveInjectEnumTag value witness functions now take a tag index in the range [-ElementsWithPayload..ElementsWithNoPayload-1]. Payload elements are numbered in *reverse* declaration order, so adding new payload cases yields decreasing tag indices, and adding new no-payload cases yields increasing tag indices, allowing use sites to be resilient. This adds the adjustment between 'fragile' and 'resilient' tag indices in a somewhat unsatisfying manner, because the calculation could be pushed down further into EnumImplStrategy, simplifying both the IRGen code and the generated IR. I'll clean this up later. In the meantime, clean up some other stuff in GenEnum.cpp, mostly abstracting code that walks cases. --- include/swift/Runtime/Metadata.h | 20 +- lib/IRGen/GenEnum.cpp | 282 ++++++++++++++-------------- lib/IRGen/GenEnum.h | 5 + lib/IRGen/GenOpaque.cpp | 4 +- lib/IRGen/GenProto.cpp | 10 +- lib/IRGen/ValueWitness.h | 10 +- stdlib/public/runtime/Reflection.mm | 7 +- test/IRGen/enum_resilience.swift | 10 +- test/IRGen/enum_value_semantics.sil | 67 ++++--- test/Inputs/resilient_enum.swift | 61 +++--- 10 files changed, 250 insertions(+), 226 deletions(-) diff --git a/include/swift/Runtime/Metadata.h b/include/swift/Runtime/Metadata.h index 82ab82339972d..09af2254c6a60 100644 --- a/include/swift/Runtime/Metadata.h +++ b/include/swift/Runtime/Metadata.h @@ -532,11 +532,14 @@ typedef int getExtraInhabitantIndex(const OpaqueValue *src, const Metadata *self); /// Given a valid object of this enum type, extracts the tag value indicating -/// which case of the enum is inhabited.

The problem is that stuff.Type is a reserved way to refer to the metatype. Solve this sort of confusion by banning type members named Type (and Protocol, while we're here) since forming a reference to them won't work. This produces a note that indicates that a backtick'd version of the identifier will work, since "stuff.`Type`" will correctly form the reference to it. This only bans type members named Type or Protocol, but we could consider banning all ValueDecls from being named Type or Protocol. Module qualification isn't widely used though, and metatypes of modules don't really make sense at the moment. --- include/swift/AST/DiagnosticsSema.def | 6 ++++++ lib/Sema/TypeCheckDecl.cpp | 22 +++++++++++++++++++--- test/decl/overload.swift | 19 +++++++++++++++++++ 3 files changed, 44 insertions(+), 3 deletions(-) diff --git a/include/swift/AST/DiagnosticsSema.def b/include/swift/AST/DiagnosticsSema.def index 290fb55d9b900..51a59eac89738 100644 --- a/include/swift/AST/DiagnosticsSema.def +++ b/include/swift/AST/DiagnosticsSema.def @@ -413,6 +413,12 @@ ERROR(serialization_target_too_new_repl,none, "module file's minimum deployment target is %0 v%1.%2%select{|.%3}3: %4", (StringRef, unsigned, unsigned, unsigned, StringRef)) +ERROR(reserved_member_name,none, + "type member may not be named %0, since it would conflict with the" + " 'foo.%1' expression", (DeclName, StringRef)) +NOTE(backticks_to_escape,none, + "backticks can escape this name if it is important to use", ()) + ERROR(invalid_redecl,none,"invalid redeclaration of %0", (DeclName)) NOTE(invalid_redecl_prev,none, "%0 previously declared here", (DeclName)) diff --git a/lib/Sema/TypeCheckDecl.cpp b/lib/Sema/TypeCheckDecl.cpp index 35c14bbfb5892..d2fbed59bea16 100644 --- a/lib/Sema/TypeCheckDecl.cpp +++ b/lib/Sema/TypeCheckDecl.cpp @@ -2662,8 +2662,24 @@ class DeclChecker : public DeclVisitor { DeclVisitor::visit(decl); - if (auto valueDecl = dyn_cast(decl)) { - checkRedeclaration(TC, valueDecl); + if (auto VD = dyn_cast(decl)) { + checkRedeclaration(TC, VD); + + // If this is a member of a nominal type, don't allow it to have a name of + // "Type" or "Protocol" since we reserve the X.Type and X.Protocol + // expressions to mean something builtin to the langauge.

This commit: - Changes the `NATIVE_TOOLS_DEPLOYMENT_TARGETS` list parameter into a single string parameter, `HOST_TARGET`. - Promotes the logic to detect the host target to Python, and places it in the `swift_build_support` module. - Removes the hard-coded "macosx_x86_64" path to the LLVM and Clang TableGen -- thereby unblocking future work to make cross-compilation possible on platforms other than OS X. - Also promotes cross-compilation target validation to Python, placing it in the `swift_build_support` module. --- utils/build-script | 16 +++++ utils/build-script-impl | 66 +++---------------- .../swift_build_support/targets.py | 43 ++++++++++++ .../swift_build_support/tests/test_targets.py | 22 +++++++ 4 files changed, 89 insertions(+), 58 deletions(-) create mode 100644 utils/swift_build_support/swift_build_support/targets.py create mode 100644 utils/swift_build_support/tests/test_targets.py diff --git a/utils/build-script b/utils/build-script index 5d5fb9dc70780..c5616cd53687d 100755 --- a/utils/build-script +++ b/utils/build-script @@ -37,6 +37,7 @@ from SwiftBuildSupport import ( sys.path.append(os.path.join(os.path.dirname(__file__), 'swift_build_support')) import swift_build_support.clang import swift_build_support.cmake +import swift_build_support.targets from swift_build_support.migration import migrate_impl_args @@ -288,6 +289,15 @@ It is a policy decision aimed at making the builds uniform across all environments and easily reproducible by engineers who are not familiar with the details of the setups of other systems or automated environments.""") + targets_group = parser.add_argument_group( + title="Host and cross-compilation targets.") + targets_group.add_argument( + "--host-target", + help="The host target.

It was disabled on Linux in 198402dcf, and further constrained to be disabled on "linux-gnu" in 83b4384fa. Since then, more flavors of Linux have become supported by Swift: "linux-gnueabihf" in 4bf81e09d, and "freebsd" in f41b791d4. Autolinking most likely does not work on any of these platforms, so mark it as unsupported for now. Other tests that only mark "linux-gnu" as unsupported do so for similar reasons. Ensure unsupported tests for "linux-gnu" are also unsupported on similar platforms. --- test/ClangModules/autolinking.swift | 4 ++++ test/Frontend/embed-bitcode.swift | 4 ++++ test/Interpreter/repl_autolinking.swift | 2 ++ test/Serialization/autolinking.swift | 4 ++++ 4 files changed, 14 insertions(+) diff --git a/test/ClangModules/autolinking.swift b/test/ClangModules/autolinking.swift index 64cd70ef25e03..3ceec2cf31182 100644 --- a/test/ClangModules/autolinking.swift +++ b/test/ClangModules/autolinking.swift @@ -11,7 +11,11 @@ // RUN: %target-swift-frontend %s -sdk %S/Inputs -I %S/Inputs/custom-modules -emit-ir -disable-autolink-framework LinkFramework -o %t/with-disabled.ll // RUN: FileCheck --check-prefix=CHECK-WITH-DISABLED %s < %t/with-disabled.ll +// Linux uses a different autolinking mechanism, based on +// swift-autolink-extract.

Using _initialize_to results in a ~10% speedup for Dictionary. For collections with more complex iteration state (such as search trees with O(log(n)) indexing), this leads to a complexity class improvement. This requires a small change to the testsuite, because the generate() method of Defaulted*RangeReplaceableSlice called Array(self), which now leads to infinite recursion. https://bugs.swift.org/browse/SR-610 --- .../private/StdlibUnittest/StdlibUnittest.swift.gyb | 8 +++++++- stdlib/public/core/ContiguousArrayBuffer.swift | 11 +---------- 2 files changed, 8 insertions(+), 11 deletions(-) diff --git a/stdlib/private/StdlibUnittest/StdlibUnittest.swift.gyb b/stdlib/private/StdlibUnittest/StdlibUnittest.swift.gyb index a0e042609ea9f..8ddd31ea43864 100644 --- a/stdlib/private/StdlibUnittest/StdlibUnittest.swift.gyb +++ b/stdlib/private/StdlibUnittest/StdlibUnittest.swift.gyb @@ -3963,7 +3963,13 @@ public struct Defaulted${traversal}RangeReplaceableSlice } public func generate() -> MinimalGenerator { - return MinimalGenerator(Array(self)) + var array: [Element] = [] + var index = startIndex + while index != endIndex { + array.append(self[index]) + index = index.successor() + } + return MinimalGenerator(array) } public subscript(index: Index) -> Element { diff --git a/stdlib/public/core/ContiguousArrayBuffer.swift b/stdlib/public/core/ContiguousArrayBuffer.swift index f74c3cd8aa54b..9df190100a590 100644 --- a/stdlib/public/core/ContiguousArrayBuffer.swift +++ b/stdlib/public/core/ContiguousArrayBuffer.swift @@ -603,16 +603,7 @@ internal func _copyCollectionToNativeArrayBuffer< count: numericCast(count), minimumCapacity: 0 ) - - var p = result.firstElementAddress - var i = source.startIndex - for _ in 0..

This drops the requirement that a fixed-layout struct only contain fixed-size things (which wasn't specified correctly anyway). Slava and Dmitri both pointed out that the previous definition had several flaws, including not really scaling to generics. This reduced version only promises that stored instance properties won't be added, removed, or modified, which is still enough to do useful optimizations. And in most cases, we'll be able to infer the full "fixed-size" property of a type from this attribute anyway. The name "fixed-contents" was chosen to force us to pick a better name later.

Also added another closeness class `CC_GenericNonsubstitutableMismatch`, which happens when more than one argument is a mismatch, but all the failing arguments are of the same type and mismatch only because of substitutability. This closeness is farther away than normal `CC_ArgumentMismatch` so that if we note expected matches, we’ll prefer non-generic matches.

This leads to a crash while assigning counters for the if_expr's "else" branch: there is no enclosing region, so grabbing the current region is impossible. We can handle this case safely by using a new leaf counter for the "else" branch.

Set type repr's as invalid after diagnosing an unsupported protocol to stop duplicate diagnoses. There were two causes here. First, top-level variable declarations were being checked once by the Decl checker, and then again by the Stmt checker. (This caused SR-38.) Second, the Stmt checker is called by an AST visitor itself, which already calls it once per statement. Using the UnsupportedProtocolVisitor here meant that each interior sub statement would get visited multiple times. Added a setRecurseIntoSubstatements() on the visitor, and set it to false for the Stmt checker.

2001 From: Slava Pestov Date: Tue, 26 Jan 2016 17:33:15 -0800 Subject: [PATCH 1695/1732] Protocol conformances can now reference resilient value types Change conformance records to reference NominalTypeDescriptors instead of metadata patterns for resilient or generic types. For a resilient type, we don't know if the metadata is constant or not, so we can't directly reference either constant metadata or the metadata template. Also, whereas previously NominalTypeDescriptors would point to the metadata pattern, they now point to the metadata accessor function. This allows the recently-added logic for instantiating concrete types by name to continue working. In turn, swift_initClassMetadata_UniversalStrategy() would reach into the NominalTypeDescriptor to get the pattern out, so that its bump allocator could be used to allocate ivar tables. Since the pattern is no longer available this way, we have to pass it in as a parameter. In the future, we will split off the read-write metadata cache entry from the pattern; then swift_initClassMetadata_UniversalStrategy() can just take a pointer to that, since it doesn't actually need anything else from the pattern. Since Clang doesn't guarantee alignment for function pointers, I had to kill the cute trick that packed the NominalTypeKind into the low bits of the relative pointer to the pattern; instead the kind is now stored out of line. We could fix this by packing it with some other field, or keep it this way in case we add new flags later. Now that generic metadata is instantiated by calling accessor functions, this change removes the last remaining place that metadata patterns were referenced from outside the module they were defined in. Now, the layout of the metadata pattern and the behavior of swift_getGenericMetadata() is purely an implementation detail of generic metadata accessors. This patch allows two previously-XFAIL'd tests to pass. --- include/swift/ABI/MetadataValues.h | 10 +-- include/swift/Runtime/Metadata.h | 58 ++++++------- lib/IRGen/GenDecl.cpp | 18 ++-- lib/IRGen/GenMeta.cpp | 45 +++++++--- lib/IRGen/IRGenModule.cpp | 5 ++ lib/IRGen/IRGenModule.h | 2 + lib/IRGen/RuntimeFunctions.def | 5 +- stdlib/public/runtime/Metadata.cpp | 13 +-- stdlib/public/runtime/MetadataLookup.cpp | 29 +++---- stdlib/public/runtime/Private.h | 2 +- stdlib/public/runtime/ProtocolConformance.cpp | 87 ++++++++++--------- test/IRGen/class_resilience.swift | 4 +- test/IRGen/generic_classes.sil | 14 +-- test/IRGen/generic_structs.sil | 12 ++- test/IRGen/protocol_conformance_records.swift | 60 +++++-------- .../protocol_conformance_records_objc.swift | 44 ++++++++++ ..._struct_fixed_layout_add_conformance.swift | 10 +++ ...ruct_fixed_layout_remove_conformance.swift | 10 +++ ...est_struct_resilient_add_conformance.swift | 14 ++- ..._struct_resilient_remove_conformance.swift | 14 ++- 20 files changed, 264 insertions(+), 192 deletions(-) create mode 100644 test/IRGen/protocol_conformance_records_objc.swift diff --git a/include/swift/ABI/MetadataValues.h b/include/swift/ABI/MetadataValues.h index 996c063e0c931..3ad9800b1bf0a 100644 --- a/include/swift/ABI/MetadataValues.h +++ b/include/swift/ABI/MetadataValues.h @@ -38,7 +38,7 @@ enum class MetadataKind : uintptr_t { }; /// Kinds of Swift nominal type descriptor records. -enum class NominalTypeKind : uintptr_t { +enum class NominalTypeKind : unsigned { #define NOMINALTYPEMETADATAKIND(name, value) name = value, #include "MetadataKind.def" }; @@ -167,10 +167,10 @@ enum class TypeMetadataRecordKind : unsigned { /// and classes could be emitted as UniqueDirectType.

Introduce Fix-Its to aid migration from selectors spelled as string literals ("foo:bar:", which is deprecated), as well as from construction of Selector instances from string literals (Selector("foo:bar"), which is still acceptable but not recommended), to the #selector syntax. Jump through some hoops to disambiguate method references if there are overloads: fixits.swift:51:7: warning: use of string literal for Objective-C selectors is deprecated; use '#selector' instead _ = "overloadedWithInt:" as Selector ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ #selector(Bar.overloaded(_:) as (Bar) -> (Int) -> ()) In the cases where we cannot provide a Fix-It to a #selector expression, we wrap the string literal in a Selector(...) construction to suppress the deprecation warning. These are also easily searchable in the code base. This also means we're doing more validation of the string literals that go into Selector, i.e., that they are well-formed selectors and that we know about some method that is @objc and has that selector. We'll warn if either is untrue. --- include/swift/AST/DeclContext.h | 5 + include/swift/AST/DiagnosticsSema.def | 15 +- include/swift/AST/Module.h | 27 ++ include/swift/ClangImporter/ClangModule.h | 4 + include/swift/Serialization/ModuleFile.h | 5 + .../Serialization/SerializedModuleLoader.h | 5 + lib/AST/Module.cpp | 32 ++ lib/AST/NameLookup.cpp | 18 + lib/ClangImporter/ClangImporter.cpp | 53 +++ lib/Sema/MiscDiagnostics.cpp | 361 ++++++++++++++++++ lib/Sema/TypeCheckDecl.cpp | 8 + lib/Serialization/ModuleFile.cpp | 19 + lib/Serialization/SerializedModuleLoader.cpp | 6 + test/ClangModules/objc_parse.swift | 10 +- .../swift-modules/Foundation.swift | 4 + .../swift-modules/ObjectiveC.swift | 4 + test/expr/unary/selector/fixits.filecheck | 7 + test/expr/unary/selector/fixits.swift | 100 +++++ 18 files changed, 677 insertions(+), 6 deletions(-) create mode 100644 test/expr/unary/selector/fixits.filecheck create mode 100644 test/expr/unary/selector/fixits.swift diff --git a/include/swift/AST/DeclContext.h b/include/swift/AST/DeclContext.h index a131ad4cf2219..e7894c89a6a9d 100644 --- a/include/swift/AST/DeclContext.h +++ b/include/swift/AST/DeclContext.h @@ -405,6 +405,11 @@ class alignas(1 << DeclContextAlignInBits) DeclContext { LazyResolver *typeResolver, SmallVectorImpl &decls) const; + /// Look up Objective-C methods with the given selector. + void lookupObjCMethods( + ObjCSelector selector, + SmallVectorImpl &results) const; + /// Return the ASTContext for a specified DeclContext by /// walking up to the enclosing module and returning its ASTContext.

Also, I decided to back out part of the change for now, where the NominalTypeDescriptor references an accessor function instead of a pattern, since this broke LLDB, which reaches into the pattern to get the generic cache. Soon we will split off the generic cache from the pattern, and at that time we can change the NominalTypeDescriptor to point at the cache. But for now, let's avoid needless churn in LLDB by keeping that part of the setup unchanged. --- include/swift/ABI/MetadataValues.h | 8 +- include/swift/Runtime/Metadata.h | 34 ++++---- lib/IRGen/GenDecl.cpp | 18 ++-- lib/IRGen/GenMeta.cpp | 2 +- lib/IRGen/IRGenModule.cpp | 5 ++ lib/IRGen/IRGenModule.h | 2 + stdlib/public/runtime/MetadataLookup.cpp | 27 +++--- stdlib/public/runtime/Private.h | 2 +- stdlib/public/runtime/ProtocolConformance.cpp | 87 ++++++++++--------- test/IRGen/protocol_conformance_records.swift | 60 +++++-------- .../protocol_conformance_records_objc.swift | 44 ++++++++++ ..._struct_fixed_layout_add_conformance.swift | 10 +++ ...ruct_fixed_layout_remove_conformance.swift | 10 +++ ...est_struct_resilient_add_conformance.swift | 14 ++- ..._struct_resilient_remove_conformance.swift | 14 ++- 15 files changed, 199 insertions(+), 138 deletions(-) create mode 100644 test/IRGen/protocol_conformance_records_objc.swift diff --git a/include/swift/ABI/MetadataValues.h b/include/swift/ABI/MetadataValues.h index 996c063e0c931..21d833580cfe4 100644 --- a/include/swift/ABI/MetadataValues.h +++ b/include/swift/ABI/MetadataValues.h @@ -167,10 +167,10 @@ enum class TypeMetadataRecordKind : unsigned { /// and classes could be emitted as UniqueDirectType.
