Richi, the only difference in generated code is by backing out your patch [1] [1] http://gcc.gnu.org/viewcvs?view=rev&revision=129796 Other suspected patches have no effect on generated code for "gfortran -march=opteron -ffast-math -funroll-loops -ftree-loop-linear -ftree-vectorize -msse3 -O3" I will check execution times, but since I have Core2, perhaps there will be no slowdown. Can you try to benchmark on your target with [1] backed out? -- ubizjak at gmail dot com changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |rguenth at gcc dot gnu dot | |org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34163
