--- Comment #1 from Segher Boessenkool <segher at gcc dot gnu.org> ---
Confirmed. define_insn_and_split "*floatuns<QHI:mode><FP_ISA3:mode>2_internal"
splits if reload_completed, so no more pseudos can be created, but it calls
gen_floatdi<FP_ISA3:mode>2 (floatdisf2 here), which creates a pseudo if you
use -mno-popcntd.
So we have enabled power9 but disabled the power7 insns. This will not fly.
(This is just one instance of a more generic problem, for which we have more
PRs already).
