--- Comment #10 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Any of the floating point to integer intrinsics if they have out of range v=
alue
(haven't checked whether floating point to unsigned intrinsic is a problem =
too
or not).
No matter if it is float or double (dunno if _Float16 too, or __bf16), and =
no
matter if it is scalar intrinsic (ss/sd etc.) or vector and how many vector
elements.
But, this isn't really a regression, GCC has always behaved that way, the o=
nly
thing that actually changed is that perhaps we can constant fold more than =
we
used to do in the past.
When not using intrinsics, IMNSHO we should keep doing what we did before.=
