Description
This is a tracking issue for the RFC "Allow loop
in constant evaluation" (rust-lang/rfcs#2344).
Steps:
- Implement the RFC (cc @rust-lang/compiler -- can anyone write up mentoring instructions?)
- Adjust documentation (see instructions on forge)
- Stabilization PR (see instructions on forge)
Unresolved questions:
- Should we add a true recursion check that hashes the interpreter state and detects if it has reached the same state again?
- This will slow down const evaluation enormously and for complex iterations is essentially useless because it'll take forever (e.g. counting from 0 to
u64::max_value()
)
