from sparc.c:
/* "v9" is used to specify a true 64 bit architecture.
"v8plus" is what Sun calls Solaris2 running on UltraSPARC's. */
{ "v8plus", PROCESSOR_V8PLUS, MASK_ISA, MASK_V9 },
Now, do you want to help us, and submit changes to the doc that
document this better so that next time we can say RTFM? ;-)
-mcpu=v8plus should work.
