I would guess just from the name that this (and some similarly named
options) apply only to Cyrix 5x86 processors. Somehow, I don't think
you'll run into too many of them in benchmarks these days. Just a
hunch.

I recall a thread somewhere recently about pentiumpro being decidedly
suboptimal for some new CPUs. Although, on 4.x with the older version
of gcc, it may not matter.
