Date: Tue, 20 Jan 2009 09:24:00 -0000	[thread overview]
Message-ID: <20090120092428.11999.qmail@sourceware.org> (raw)

------- Comment #3 from vincenzo dot innocente at cern dot ch  2009-01-20 09:24 -------
I confirm that gcc 4.2.3 is as fast as 4.1 and at least twice as slow of gcc
4.3.2
test done on an intel core2 running RHL4 and core i7 with RHL5.
mtune either generic or native (no difference)
