--- Comment #4 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:11f7d5648c42cd2ef6f0841cde6292b94831e7b6 commit r16-3186-g11f7d5648c42cd2ef6f0841cde6292b94831e7b6 Author: Andrew Pinski <andrew.pin...@oss.qualcomm.com> Date: Wed Aug 13 09:19:42 2025 -0700 forwprop: Move check of limit first [PR121474] This is the first step in handling the review part of: https://gcc.gnu.org/pipermail/gcc-patches/2025-August/692091.html ''' Oh, as we now do alias walks in forwprop maybe we should make this conditional and do this not for all pass instances, since it makes forwprop possibly a lot slower? ''' The check of the limit was after the alias check which could slow down things. This moves the check of the limit to begining of the if. Bootstrapped and tested on x86_64-linux-gnu. Pushed as obvious. PR tree-optimization/121474 gcc/ChangeLog: * tree-ssa-forwprop.cc (optimize_aggr_zeroprop): Move the check for limit before the alias check.
