From: "msebor at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug tree-optimization/98512] [11 Regression] “#pragma GCC diagnostic ignored” ineffective in conjunction with alias attribute Date: Tue, 05 Jan 2021 00:34:33 +0000 [thread overview] Message-ID: <bug-98512-4-OIEfP9XvDE@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-98512-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=98512 Martin Sebor <msebor at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Known to fail| |11.0 Status|UNCONFIRMED |NEW Summary|“#pragma GCC diagnostic |[11 Regression] “#pragma |ignored” ineffective in |GCC diagnostic ignored” |conjunction with alias |ineffective in conjunction |attribute |with alias attribute Last reconfirmed| |2021-01-05 Ever confirmed|0 |1 Known to work| |10.2.0 --- Comment #1 from Martin Sebor <msebor at gcc dot gnu.org> --- The warning looks for the location into which the memchr caller was inlined (to see if the caller is defined in a system header but itself called from user code). Without the alias it doesn't find one (because the caller isn't called from anywhere) but with the alias it finds the memchr caller, __rawmemchr_ppc.
