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.
