You can have a look at the AltiVec cross reference sheet here :
http://developer.apple.com/hardwaredrivers/ve/instruction_crossref.html
and the assorted guides on the old apple velocity engine:
http://developer.apple.com/hardwaredrivers/ve/code_optimization.html
http://developer.apple.com/hardwaredrivers/ve/throughput_vs_latency.html
note that most of these techniques are cross-extension (especially
abusing the silent casting of vectors and the mask-select instead of
if-then-else.)
You can get a short overview of these in our boost'con talk from last
year. It may also be nice if you read up on proto as we use it quite
intensively.
