--- Comment #7 from iii at gcc dot gnu.org --- Author: iii Date: Thu Nov 14 16:40:33 2019 New Revision: 278254 URL: https://gcc.gnu.org/viewcvs?rev=278254&root=gcc&view=rev Log: Make flag_thread_jumps a gate of pass_jump_after_combine This is a follow-up to https://gcc.gnu.org/ml/gcc-patches/2019-11/msg00919.html (r278095). Dominance info is deleted even if we don't perform jump threading. Since the whole point of this pass is to perform jump threading (other cleanups are not valuable at this point), skip it completely when flag_thread_jumps is not set. gcc/ChangeLog: 2019-11-14 Ilya Leoshkevich <i...@linux.ibm.com> PR rtl-optimization/92430 * cfgcleanup.c (pass_jump_after_combine::gate): New function. (pass_jump_after_combine::execute): Perform jump threading unconditionally. Modified: trunk/gcc/ChangeLog trunk/gcc/cfgcleanup.c
