--- Comment #5 from Segher Boessenkool <segher at gcc dot gnu.org> ---
See rs6000.c:validate_condition_mode.  This is:

r36191 (from 2000), original;
r39610 (from 2001), -ffast-math;
r40300 (from 2001), -funsafe-math-optimizations;
r55904 (from 2002), -ffinite-math-only.

So it took some time to get it to this, but that is all ages ago.

Should there be UNLT during gimple, even with -ffinite-math-only?  Should
expand then convert that do something saner already?  Or should it not be
generated in gimple either?
