I don't think there is any apart from the errata page:
http://developer.apple.com/hardware/ve/errata.html
Largely the API hasn't changed since MacOS 9 for that segment of
vecLib. The major difference is that it is now part of
Accelerate.framework, and you need to link using:
-framework Accelerate
There have been some additions. We added a bunch of double precision
variants on the old single precision APIs in MacOS X.2. They work just
the same as the single precision variants, except that they are not
vectorized. (Altivec doesn't do double precision.) In MacOS X.3 (and
the version of MacOS X.2 that shipped with the first G5s), some of the
back ends were retuned for G5, but this had no effect on the front end
API, except as noted in the errata.
