--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
So shall we use the UNSPEC_IEEE_MIN/MAX patterns instead of the max/min RTL for
the non-fast-math case? Either generate those unspecs in the expanders if
honoring nans or signed zeros, or use different expanders for the intrinsics
that do that?
There is:
;; ??? For !flag_finite_math_only, the representation with SMIN/SMAX
;; isn't really correct, as those rtl operators aren't defined when
;; applied to NaNs. Hopefully the optimizers won't get too smart on us.
comment, as the intrinsics are preserved as md builtin calls during GIMPLE and
I don't think we have gimple folders for those, it means the RTL optimizers are
finally smart enough...
