(In reply to Segher Boessenkool from comment #11)
> Confirmed the comment 4 problem, on all archs.  This is a very old bug.

There are two ways to fix this bug:
1. Change flag_unsafe_math_optimizations to flag_finite_math_only, so that
fmaxnm/fminnm can be generated under -ffinite-math-only;
2. Delete this optimization.
Which one do you prefer?=
