That was what I assumed. I don't think there is such a flag at this point.

We do have memory prefetch instructions on PA2.0 processors, but (again,
from the conversation at GCC Summit), GCC hasn't been taught about
them yet. This should be considerably easier to do than the half-word
saturated arithmetic stuff.
As far as vectorized floating point, PA doesn't have it. The designers
seem to have considered vectorized fixed-point / integer arithmetic as
more important.
