Re: Loop unrolling-related SPEC regressions?



Here're the results of:
Base Compiler: GCC CVS as of Feb 5 2002 8am UTC
Peak Compiler: base plus reversion of loop unrolling patch
cflags base: -fomit-frame-pointer -march=athlon -funroll-loops -fstrict-aliasing -malign-double
cflags peak: -fomit-frame-pointer -march=athlon -funroll-loops -fstrict-aliasing -malign-double
Iterations: 3

Tell me if you like to see other runs,

Andreas
