From: "hubicka at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug target/43052] Inline memcmp is *much* slower than glibc's Date: Wed, 10 Nov 2010 21:36:00 -0000 [thread overview] Message-ID: <bug-43052-4-Se9ViF95OY@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-43052-4@http.gcc.gnu.org/bugzilla/> http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43052 --- Comment #4 from Jan Hubicka <hubicka at gcc dot gnu.org> 2010-11-10 21:36:07 UTC --- Hmm, I should read testcases curefully. It is memcmp. GCC is not really smart on inlining this; I guess we should just disable the inline unless we optimize for size since we don't really have enough info to inline it well by default.
