--- Comment #6 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The trunk branch has been updated by Richard Sandiford <rsand...@gcc.gnu.org>: https://gcc.gnu.org/g:f6081ee665fd5e4e7d37e02c69d16df0d3eead10 commit r15-1696-gf6081ee665fd5e4e7d37e02c69d16df0d3eead10 Author: Richard Sandiford <richard.sandif...@arm.com> Date: Thu Jun 27 14:51:37 2024 +0100 Disable late-combine for -O0 [PR115677] late-combine relies on df, which for -O0 is only initialised late (pass_df_initialize_no_opt, after split1). Other df-based passes cope with this by requiring optimize > 0, so this patch does the same for late-combine. gcc/ PR rtl-optimization/115677 * late-combine.cc (pass_late_combine::gate): New function.
