--- Comment #3 from Hongtao.liu <crazylht at gmail dot com> --- I think it's related to r12-2666 which caused load-to-store-forwarding stall issue, and we're working on pr103734, try to improve ipa-inline. w -param=inline-min-speedup=3, we observe both performance improvement and codesize decrease. Plan to land on GCC13.
