As Martin says, %qs for this and similar (see the documentation before
pp_format in pretty-print.c). Can be a separate patch of course, this
one is big enough already.

Let's either keep AltiVec or say -maltivec. We only have this warning
because we allow -maltivec with CPUs that do not support it; and this
warning is only for some of the FSL CPUs. It isn't very consistent.

See also PR79477. Since many of these options are going away it is
probably not worth spending too much time on this, not until stage 3
or so anyway.

Maybe the warning should just say "big vector"? Or "generic vector"?
(Vectors that fit in one VR, or in GPRs in 8 bytes or less, do not have
the problem this warns for. Kind of hard to express tersely and
precisely though).
Approved for trunk with whichever of the suggested changes you think
are good. Thanks,
Segher
