--- Comment #18 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:af1634f1b555004753a22d1124dbb8419ee095cb commit r11-192-gaf1634f1b555004753a22d1124dbb8419ee095cb Author: Jakub Jelinek <ja...@redhat.com> Date: Fri May 8 09:30:54 2020 +0200 csa: Fix --enable-checking=yes,df bootstrap failure in csa [PR94961] My recent combine-stack-adj.c change broke df checking bootstrap, while most of the changes are done through validate_change/confirm_changes which update df info, the removal of REG_EQUAL notes didn't update df info. 2020-05-08 Jakub Jelinek <ja...@redhat.com> PR bootstrap/94961 PR rtl-optimization/94516 * rtl.h (remove_reg_equal_equiv_notes): Add a bool argument defaulted to false. * rtlanal.c (remove_reg_equal_equiv_notes): Add no_rescan argument. Call df_notes_rescan if that argument is not true and returning true. * combine.c (adjust_for_new_dest): Pass true as second argument to remove_reg_equal_equiv_notes. * postreload.c (reload_combine_recognize_pattern): Don't call df_notes_rescan.
