--- Comment #4 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Martin Jambor <jamb...@gcc.gnu.org>: https://gcc.gnu.org/g:2e97d6443f0a862ce9b798084499635914e3b8c6 commit r11-5000-g2e97d6443f0a862ce9b798084499635914e3b8c6 Author: Martin Jambor <mjam...@suse.cz> Date: Fri Nov 13 18:30:11 2020 +0100 ipa-cp: One more safe_add (PR 97816) The new behavior of safe_add triggered an ICE because of one use where it had not been used instead of a simple addition. I'll fix it with the following obvious patch so that periodic benchmarkers can continue working because a proper fix (see below) will need a review. The testcase showed me, however, that we can propagate time and cost from one lattice to another more than once even when that was not the intent. I'll address that as a follow-up after I verify it does not affect the IPA-CP heuristics too much or change the corresponding params accordingly. Bootstrapped and tested on x86_64-linux. gcc/ChangeLog: 2020-11-13 Martin Jambor <mjam...@suse.cz> PR ipa/97816 * ipa-cp.c (value_topo_info<valtype>::propagate_effects): Use safe_add instead of a simple addition.
