Subject: [Bug middle-end/32940] REG_POINTER attribute on DECL_ARTIFICIAL pointers
Date: Fri, 03 Aug 2007 15:30:00 -0000 [thread overview]
Message-ID: <20070803153019.26571.qmail@sourceware.org> (raw)
In-Reply-To: <bug-32940-11700@http.gcc.gnu.org/bugzilla/>
------- Comment #5 from pthaugen at us dot ibm dot com 2007-08-03 15:30 -------
This patch gives us an additional 2-3% overall on CPU2000, running on Power6.
Facerec was the big winner with about 40% improvement, there were a few
improvements in the 5-10% range and a few degradations in the 1-2% range that
could be attributed to other issues like loop alignment or possibly an issue
with r0 getting assigned to the base reg by renaming which I'm currently
testing a patch for.
