Subject: [Bug rtl-optimization/21507] [4.0/4.1 Regression] BYTEmark floating-point emulation: Regression with -O3
Date: Mon, 10 Jul 2006 12:32:00 -0000	[thread overview]
Message-ID: <20060710123217.21081.qmail@sourceware.org> (raw)
In-Reply-To: <bug-21507-10607@http.gcc.gnu.org/bugzilla/>



------- Comment #4 from rguenth at gcc dot gnu dot org  2006-07-10 12:32 -------
Numbers for  -static -O3 -march=pentium4 -fomit-frame-pointer  (on a P4)

3.4.6:  8.1s
4.0.3:  7.3s
4.1.1: 13.5s
4.2.0:  4.2s

(is there a correctness check inside the benchmark?)

with FDO:

3.4.6:  5.8s
4.0.3:  9.8s
4.1.1: 10.5s
4.2.0:  4.2s

indeed interesting that we loose on FDO for 4.0, and bad
that we're that much slower for 4.1.  Good for mainline though.
