Date: Fri, 15 Oct 2021 15:23:40 +0000 (GMT) [thread overview] Message-ID: <20211015152340.D6E9C3858432@sourceware.org> (raw) https://gcc.gnu.org/g:cd9891ec3eed3a5b289b7c556598606d21e48206 commit cd9891ec3eed3a5b289b7c556598606d21e48206 Author: Martin Liska <mliska@suse.cz> Date: Wed Oct 13 14:20:33 2021 +0200 rs6000: Remove unnecessary option manipulation. gcc/ChangeLog: * config/rs6000/rs6000.c (rs6000_override_options_after_change): Do not set flag_rename_registers, it's already default behavior. Use EnabledBy for unroll_only_small_loops. * config/rs6000/rs6000.opt: Use EnabledBy for unroll_only_small_loops.
