Segher Boessenkool <segher at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |segher at gcc dot gnu.org --- 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).
