Re: [PATCH 0/2] fix RISC-V zcmp popretz [PR113715]

[Kito Cheng <kito.cheng@gmail.com>]

Thanks for fixing this issue, and I am wondering doest it possible to
fix that without introduce target hook? I ask that because...GCC 14
also has this bug, but I am not sure it's OK to introduce new target
hook for release branch? or would you suggest we just revert patch to
fix that on GCC 14?
