Pull Request Overview
This PR updates the JIT epilog logic to prevent overriding the argument register when a jmp operation is used, porting a change from PR #114861.
- The condition in genFnEpilog now checks that compJmpOpUsed is false before proceeding.
- This change ensures the "pop ecx" instruction is only executed when it’s safe to do so.
