altivec

[Brad Midgley]

i should have explained this more. the library can't be abstracted at the
level of "multiply these numbers..." it would have to be abstracted at a
much higher level, such as "perform a single-precision fft up to frequency
q" with a mathematician devising what high-level operations are useful.

> the tough part will be designing a shared library and abstracting its
> entry points with an eye on performance both with and without simd
> capability. this is a problem that transcends altivec--it is relevant
> to simd processor extensions on other architectures too.
