Bill Schmidt <wschmidt at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |wschmidt at gcc dot gnu.org --- Comment #5 from Bill Schmidt <wschmidt at gcc dot gnu.org> --- So technically, if the target is 32-bit powerpc, the ABI is silent on the upper 32 bits. That's not necessarily a reasonable position to stand on, but when targeting powerpc (not powerpc64*) those bits are meaningless.
