I've got diverging scripts on various systems, and when I thought I was testing
with a compiler from before 20050630 I was actually using today's mainline.
I have verified (and triple-checked) that none of the failures I currently see
in SPEC CPU2000 when using profile-generate/profile-use show up just before the
patch at http://gcc.gnu.org/ml/gcc-cvs/2005-06/msg01108.html. Many of them show
up immediately after that patch, and others creep in later. Among the failures
immediately after the patch are
gap with profopts -O3 -m64
gcc with profopts -O3 -m32/-m64
twolf with profopts -O3 -m32/-m64
vpr with profopts -O3 -m32/-m64
No minimized testcase yet.
