Wasmtime GitHub notifications bot (Mar 11 2025 at 18:36):fitzgen opened PR #10372 from fitzgen:issue-10353 to bytecodealliance:main:
As an optimization, we were previously avoiding the load and instead simply materializing the null reference value, since that is the only value that inhabits
(ref null none). However, in certain situations, such as when loading from a table when Spectre mitigations are enabled, we rely on that load being attempted and resulting in a trap if the table index is out of bounds. This commit makes it so that we will always perform the load if our givenir::MemFlagscan trap.Fixes #10353
