--- Comment #8 from Segher Boessenkool <segher at gcc dot gnu.org> ---
Yeah, it tested for ISA 2.04 before. That was an attempt at including 476
probably?
We really should have a TARGET_FCTID, on for TARGET_POWERPC64 or for cpu 476
(so
NOT user-selectable separately, of course!); not try to use pre-existing flags
for this, which might work but will forever stay confusing.
So either a separate OPTION_FCTID for in rs6000-cpus.def, or TARGET_FCTID.
Either
works for me.
(Background: in ISA 1.xx it was for 64-bit implementations only. But it does
not
need 64-bit registers or a 64-bit integer pipeline at all, it is an FP
instruction
that works on FP registers, which always are 64-bit. The instruction was
implemented
on the 476).
