------- Comment #3 from burnus at gcc dot gnu dot org 2008-08-18 16:09 -------
Same trend with "ifort -O3" (ifort 11beta) and "gfortran -O3 --fast-math
-march=native" on AMD Athlon64 X2 4800+ / openSUSE 11. [same mulsd/mulpd
numbers]
ifort 2.452s, gfortran 3.848s -> 57% slower.
With Richard's patch: 3.040s (and mulsd = 0; mulpd = 140)
