From: "pinskia at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug target/112615] gcc incorrectly assumes char *x[2]={"str1", "str2"} has 16-byte minimum alignment and generates SSE instructions (e.g. movaps) when accessing this data Date: Sun, 19 Nov 2023 02:17:38 +0000 [thread overview] Message-ID: <bug-112615-4-NFseUwUg7y@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-112615-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=112615 --- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> --- . Or their sources for Oracle DB ... I suspect they have an assembly file that contains that variable and didn't realize the alignment rules. Note GCC 4.1.2 even sets the alignment to 16 for a simple: char *x[2]={"str1", "str2"};
