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.
