Is avx instruction updated in this manual?

I don't have time to add them. We also need to design first how AVX instructions should be added because they use backward incompatible instruction format.

I am learning to see if I can contribute code to you.

Do you have experience with coding with AVX instructions?

The most important is figuring out AVX instruction operand codes. These can be seen in the geek editions, see for example ADDPS Vps, Wps. There are no AVX codes defined in the reference at the moment.

I think that Intel manual defines the AVX operand codes; also sandpile.org should help.

In short, we should start with a table of AVX operand codes, completing this one, inspired by Intel manual and sandpile.org.

I don't have experience in avx instruction, but I just used the avx command. I refer to the official manual of intel.

I work on the VEX-encoded instructions now but not sure when it will be finished.
