alexcrichton opened PR #12876 from alexcrichton:x64-shrink-not to bytecodealliance:main:

This commit fixes a minor issue where a not instruction was translated with a 64-bit width when the input was a 32-bit value. This didn't end up actually affecting the semantics of the instruction itself but it's not necessary to have a full 64-bit negation, so this commit updates it to a 32-bit negation which was the original intention here.
