--- Comment #9 from Peter Bergner <bergner at gcc dot gnu.org> --- So the problem is that the splitter for vsx_div_v2di unconditionally calls gen_divdi3() , which assumes we have a 64-bit integer HW div insn. If you do a scalar 64-bit div, we notice we don't have that HW insn and expand calls the __divdi3 library function. Maybe in gen_divdi3() we could detect whether we need to do that same? I'll see if I can come up with something.
