MMBENCH4s.tar.gz + assembly without and with patch
I don't know what was wrong, but you can now fetch the patch yourself from
http://gcc.gnu.org/ml/gcc-patches/2006-08/msg00113.html
Anyway, here's your .tar.gz now including the .s files (and the Makefile points
to my gcc's). ?mm_3.s is the unpatched GCC 4.2, ?mm_4.s is the patched one.
