How about 8445, 9654? Those are "bugs" that disappear with -ffloat-store, too. Like I said, I don't know enough about floating point numbers...
Toon seems to think that PR fortran/8445 is indeed the same problem. But it's up to him to decide whether to close the bug.Exactly - however, I feel I cannot close these reports because I do not have access to x86 hardware anymore, so I cannot easily test whether they indeed *are* -ffloat-store issues ....
PR optimization/9654 is exactly the same problem: using FP registers on x86 adds extra-precision which can modify comparison results. Nothing can be done about that, other than using -ffloat-store which is precisely intended to address the issue.
