--- Comment #5 from Haochen Jiang <haochen.jiang at intel dot com> ---
It seems that mainly caused by codesize increase in GCC14 since the actual
instruction retired increase ratio is similar to the regression.

Also, just like PR114987, I tried with GCC11, seems it gets the better
performance than GCC13.
