Date: Wed, 24 Jan 2024 07:38:25 +0000 (GMT) [thread overview] Message-ID: <20240124073825.D543F3858D38@sourceware.org> (raw) https://gcc.gnu.org/g:59004711660065a731be07c92150d45de430a550 commit r14-8383-g59004711660065a731be07c92150d45de430a550 Author: Tamar Christina <tamar.christina@arm.com> Date: Wed Jan 24 07:38:18 2024 +0000 middle-end: rename main_exit_p in reduction code. This renamed main_exit_p to last_val_reduc_p to more accurately reflect what the value is calculating. gcc/ChangeLog: * tree-vect-loop.cc (vect_get_vect_def, vect_create_epilog_for_reduction): Rename main_exit_p to last_val_reduc_p.
