Subject: [Bug middle-end/32044] [4.3 regression] udivdi3 counterproductive, unwarranted use
Date: Tue, 27 Nov 2007 05:56:00 -0000	[thread overview]
Message-ID: <20071127055557.25108.qmail@sourceware.org> (raw)
In-Reply-To: <bug-32044-11706@http.gcc.gnu.org/bugzilla/>



------- Comment #28 from ismail at pardus dot org dot tr  2007-11-27 05:55 -------
Mark,

Linux 2.6 tree as of this minute doesn't compile with gcc 4.3 trunk. You need
to add -fno-tree-scev-cprop to the KBUILD_CFLAGS, but this is not upstreamed
yet and I am not sure if it'll be accepted in case it results in a performance
regression.

Thanks.
