------- Comment #21 from rguenth at gcc dot gnu dot org 2006-10-24 09:23 -------
Ah well, this seems to be documented as such:
-mieee-fp
-mno-ieee-fp
Control whether or not the compiler uses IEEE floating point comparisons.
These handle correctly the case where the result of a comparison is unordered.
so it really only affects FP comparisons.
Closing as fixed, we can open another bug if the above is really a problem.
