--- Comment #16 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:f2818238a53f518bb1be178acf388d978443c1e2 commit r16-3993-gf2818238a53f518bb1be178acf388d978443c1e2 Author: Andrew Pinski <andrew.pin...@oss.qualcomm.com> Date: Tue Sep 16 15:42:54 2025 -0700 forwprop: Don't loop on the stmt when optimize_aggr_zeroprop or optimize_agr_copyprop return true Since now optimize_aggr_zeroprop and optimize_agr_copyprop work by forward walk to prop the zero/aggregate and does not change the statement at hand, there is no reason to repeat the loop if they do anything. This will prevent problems like PR 121962 from happening again as we will never loop. Bootstrapped and tested on x86_64-linux-gnu. gcc/ChangeLog: * tree-ssa-forwprop.cc (optimize_aggr_zeroprop_1): Change return type to void. (optimize_aggr_zeroprop): Likewise. (optimize_agr_copyprop_1): Likewise. (optimize_agr_copyprop_arg): Likewise. (optimize_agr_copyprop): Likewise. (simplify_builtin_call): Handle update of the return type of optimize_aggr_zeroprop. (pass_forwprop::execute): Likewise and optimize_agr_copyprop. Signed-off-by: Andrew Pinski <andrew.pin...@oss.qualcomm.com>
