vec_xor is the Altivec (G4 & G5) command to do an XOR on a 128bit wide vector.
There is also an intel-specific instruction _mm_xor --- something.
The vecLib is supposed to offer processor-universal instructions - and come on, XOR is about the simplest thing you can ask a computer to do. Yet, there seem to be no raw-bitwise operations in there - plenty of image processing, signal processing, and so forth, but no plain old boolean logic.
Anyone know if I've missed something?
