--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Or perhaps ifcvt.c should gen_cond_trap only if the arguments already satisfy
ctrap<mode>4's predicates and punt if not.
So perhaps avoid calling gen_cond_trap altogether, and instead do what it does
except for the prepare_cmp_insn and do insn_operand_matches on all the
operands?
The #c3 patch isn't that ugly either.
