-Subject: [PATCH] Remove crypt and crypt_r interceptors
-
-From Florian Weimer's D144073
-
-> On GNU/Linux (glibc), the crypt and crypt_r functions are not part of the main shared object (libc.so.6), but libcrypt (with multiple possible sonames). The sanitizer libraries do not depend on libcrypt, so it can happen that during sanitizer library initialization, no real implementation will be found because the crypt, crypt_r functions are not present in the process image (yet). If its interceptors are called nevertheless, this results in a call through a null pointer when the sanitizer library attempts to forward the call to the real implementation.
->
-> Many distributions have already switched to libxcrypt, a library that is separate from glibc and that can be build with sanitizers directly (avoiding the need for interceptors). This patch disables building the interceptor for glibc targets.
-
-Let's remove crypt and crypt_r interceptors (D68431) to fix issues with
-newer glibc.
-
-For older glibc, msan will not know that an uninstrumented crypt_r call
-initializes `data`, so there is a risk for false positives. However, with some
-codebase survey, I think crypt_r uses are very few and the call sites typically
-have a `memset(&data, 0, sizeof(data));` anyway.

+Subject: [PATCH] libsanitizer: also undef _TIME_BITS in
+ sanitizer_procmaps_solaris.cpp
+
+Upstream commit
+https://github.com/llvm/llvm-project/commit/26800a2c7e7996dc773b4e990dd5cca41c45e1a9
+of LLVM added a #undef _TIME_BITS in
+libsanitizer/sanitizer_common/sanitizer_platform_limits_posix.cpp to
+fix the build on 32-bit Linux platforms that have enabled 64-bit
+time_t using _TIME_BITS=64.
+
+Indeed, _TIME_BITS=64 can only be used when _FILE_OFFSET_BITS=64, but
+sanitizer_platform_limits_posix.cpp undefines _FILE_OFFSET_BITS before
+including any header file. To fix this, the upstream fix was to also
+undef _TIME_BITS.
+
+This commit simply does the same in sanitizer_procmaps_solaris.cpp,
+which also gets compiled under Linux (despite what the file name
+says). In practice on Linux hosts (where _TIME_BITS=64 matters),
+sanitizer_procmaps_solaris.cpp will expand to nothing, as pretty much
+the rest of the file is inside a #ifdef SANITIZER_SOLARIS...#endif. So
+the #undef _FILE_OFFSET_BITS and #undef _TIME_BITS are only here
+before including sanitizer_platform.h, which will set the
+SANITIZER_LINUX/SANITIZER_SOLARIS define depending on the platform.
+
+Fixes:
+
+armeb-buildroot-linux-gnueabi/sysroot/usr/include/features-time64.h:26:5: error: #error "_TIME_BITS=64 is allowed only with _FILE_OFFSET_BITS=64"
+   26 | #   error "_TIME_BITS=64 is allowed only with _FILE_OFFSET_BITS=64"

+Subject: [PATCH] MicroBlaze : Enhance support for atomics. Fix PR118280
+
+Atomic support enhanced to fix existing atomic_compare_and_swapsi pattern
+to handle side effects; new patterns atomic_fetch_op and atomic_test_and_set
+added. As MicroBlaze has no QImode test/set instruction, use shift magic
+to implement atomic_test_and_set. This fixes PR118280.
+
+Files Changed
+
+* gcc/config/microblaze/iterators.md: New
+* microblaze-protos.h/microblaze.cc : Add microblaze_subword_address
+* gcc/config/microblaze/microblaze.md: constants: Add UNSPECV_CAS_BOOL,
+  UNSPECV_CAS_MEM, UNSPECV_CAS_VAL, UNSPECV_ATOMIC_FETCH_OP
+  type: add atomic
+* gcc/config/microblaze/sync.md: Add atomic_fetch_<atomic_optab>si
+  atomic_test_and_set

+Fix libstdc++ include paths for candian cross builds
+
+In a true canadian cross build, libstdc++ is built with the "target" compiler.
+This is a cross compiler and it is therefore harmful to use the build machine
+standard include paths. Instead, we can rely on the fact that the C and libc
+header files are found naturally by the cross-compiler in its sysroot.

+From: Jan Kloetzke <jan@kloetzke.net>
+Subject: Fix build sysroot includes
+
+If a build sysroot was passed to configure (--with-build-sysroot=), we must not
+pick up libraries or headers from the installation destination. These locations
+will potentially contain incompatible files. Instead, the build sysroot is
+already passed to the compiler and will find the correct libs/headers there.

-From: Jan Kloetzke <jan@kloetzke.net>
-Subject: Fix sysroot if stripping is disabled
-
-When disabling CONFIG_BID_STRIP_BINARIES, BID will just use symlinks when
-"installing" libraries. This does not work with the sysroot target when a
-SOVERSION is set for the library. To fix that, fall back to a copy.
