From: "steven at gcc dot gnu dot org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug rtl-optimization/30688] Branch registers loaded too late on ia64 Date: Fri, 06 Feb 2009 21:21:00 -0000 [thread overview] Message-ID: <20090206212119.8718.qmail@sourceware.org> (raw) In-Reply-To: <bug-30688-7834@http.gcc.gnu.org/bugzilla/> ------- Comment #2 from steven at gcc dot gnu dot org 2009-02-06 21:21 ------- GCC has the bt-load optimization for this. But this code is not enabled for ia64. It could be so simple as just setting flag_branch_target_optimize{,2} to true in the ia64 backend, but maybe more work is needed (I have never looked at bt-load.c). -- steven at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |NEW Ever Confirmed|0 |1 Keywords| |missed-optimization Last reconfirmed|0000-00-00 00:00:00 |2009-02-06 21:21:19 date| | http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30688
