These are a distressingly low numbers. i would have expected this bug
to get a lot more hits on the fortran benchmarks.
SPEC CPU2000 fp has 10 fortran programs.
This means more than half of them failed with -m64.
That doesn't sound ""distressingly low",
although if you expect it to fail whenever
modulo scheduler worked, certainly this looks low
- probably that's more of an issue for the modulo scheduler than anything else.
