| For example I need a xor.128 instruction so I can xor 128 bits at a time. Useful for encryption/decryption routines. If u can't afford xor.128 then I will happily settle for xor.256 :)

| can you add an example of your code, maybe Bgun can add some new instruction to semplify / speedup the execution?

Hello again James. According to another thread at CLICK HERE the XOR has currently been overlooked and the vector ops are currently 64 bits. I don't foresee a difficulty in adding a PXOR opcode since it already has PAND, POR, and PANDN along with much more complex ops such as a PMULH and PMULL. We do need some documentation to go with the names though, admittedly.

| 64bit PEOR is of course already included. That is was not included on the list in the forum post was only a copy-paste error.
