Subject: [Bug tree-optimization/32921] [4.3 Regression] Revision 126326 causes 12% slowdown
Date: Sat, 31 Jan 2009 14:27:00 -0000 [thread overview]
Message-ID: <20090131142647.18156.qmail@sourceware.org> (raw)
In-Reply-To: <bug-32921-682@http.gcc.gnu.org/bugzilla/>
------- Comment #58 from bonzini at gnu dot org 2009-01-31 14:26 -------
> Btw, on x86_64 leslie3d performance is now above that from before r126326.
Changing to 4.3 only. A separate bug (likely not a regression) should be
opened for the testcase of comment #47.
Might even be WONTFIX for 4.3.
