From: Martin Liska <marxin@gcc.gnu.org> To: gcc-cvs@gcc.gnu.org Subject: [gcc r13-5631] ipa: silent -Wodr notes with -w Date: Wed, 1 Feb 2023 14:44:37 +0000 (GMT) [thread overview] Message-ID: <20230201144437.54CF23858436@sourceware.org> (raw) https://gcc.gnu.org/g:8a7196977f6e91ad12c209cb2e3dbfe9f0fd3c3b commit r13-5631-g8a7196977f6e91ad12c209cb2e3dbfe9f0fd3c3b Author: Martin Liska <mliska@suse.cz> Date: Fri Dec 2 11:37:41 2022 +0100 ipa: silent -Wodr notes with -w If -w is used, warn_odr properly sets *warned = false and so it should be preserved when calling warn_types_mismatch. Noticed that during a LTO reduction where I used -w. gcc/ChangeLog: * ipa-devirt.cc (odr_types_equivalent_p): Respect *warned value if set.
