--- Comment #9 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jan Hubicka <hubi...@gcc.gnu.org>: https://gcc.gnu.org/g:efcbe7b985e24ac002a863afd609c44a67761195 commit r15-2207-gefcbe7b985e24ac002a863afd609c44a67761195 Author: Jan Hubicka <hubi...@ucw.cz> Date: Mon Jul 22 23:01:50 2024 +0200 Fix handling of ICF_NOVOPS in ipa-modref As shown in somewhat convoluted testcase, ipa-modref is mistreating ECF_NOVOPS as "having no side effects". This come from time when modref cared only about memory accesses and thus it was possible to shortcut on it. This patch removes (hopefully) all those bad shortcuts. Bootstrapped/regtested x86_64-linux, comitted. gcc/ChangeLog: PR ipa/109985 * ipa-modref.cc (modref_summary::useful_p): Fix handling of ECF_NOVOPS. (modref_access_analysis::process_fnspec): Likevise.
