Wasmtime GitHub notifications bot (Jan 25 2026 at 03:09): Wasmtime GitHub notifications bot (Jan 25 2026 at 03:09):alexcrichton opened PR #12427 from alexcrichton:fixup-and-check-may-leave to bytecodealliance:main:
This commit moves all may-leave flag handling into compiled trampolines rather than doing this in Rust. This means it can't be forgotten on the Rust side of things and will be slightly more efficient to boot. This then additionally exempts some intrinsics from checking may-leave since Wasmtime erroneously checked when it shouldn't have.
Closes #12397

This is a draft for now because the new tests I added are failing (some intrinsics aren't supporting being called in post-return for example) and I need to bottom that out.
