alexcrichton opened PR #9575 from alexcrichton:x64-conditional-traps to bytecodealliance:main:

This commit improves the lowering rules on x64 for conditional traps (e.g. trapz and trapnz) to include a special-case with icmp which enables removing some extra instructions by materializing a comparison result into a register.
