--- Comment #8 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The trunk branch has been updated by Andrew Pinski <pins...@gcc.gnu.org>: https://gcc.gnu.org/g:aa972d027437784686dfc66180dc1b640e7dbb39 commit r15-7495-gaa972d027437784686dfc66180dc1b640e7dbb39 Author: Andrew Pinski <quic_apin...@quicinc.com> Date: Tue Feb 11 15:13:07 2025 -0800 ifcvt: Don't speculation move inline-asm [PR102150] So unlike loop invariant motion, moving an inline-asm out of an if is not always profitable and the cost estimate for the instruction inside inline-asm is unknown. This is a regression from GCC 4.6 which didn't speculatively move inline-asm as far as I can tell. Bootstrapped and tested on x86_64-linux-gnu. PR rtl-optimization/102150 gcc/ChangeLog: * ifcvt.cc (cheap_bb_rtx_cost_p): Return false if the insn has an inline-asm in it. Signed-off-by: Andrew Pinski <quic_apin...@quicinc.com>
