If we match on the altname, then we return the canonical name.
Don't add this to rs6000-cpus.def; it belongs to the Linux support only. You also need to translate multiple AT_PLATFORM names for a single -mcpu=, not necessarily only two, so you probably want a separate translation table to do just the translation (in driver-rs6000.c ?) Did you check this against the kernel's arch/powerpc/kernel/cputable.c ? Segher
