[fpc-devel] AVX 512 - Can't compile vaddps zmm1, zmm2, zmm3

[Joao Schuler]

Thank you Kit.

[VADDPS]
(Ch_Wop3, Ch_Rop2, Ch_Rop1)
xmmreg,xmmreg,xmmrm                  \362\370\1\x58\75\120
AVX,SANDYBRIDGE
ymmreg,ymmreg,ymmrm                  \362\364\370\1\x58\75\120
AVX,SANDYBRIDGE

In regards to the opcode, what is the base (doesn't look hexa) for these
numbers? Example:

\362\364\370\  - are these 16 bits numbers (too big for bytes)?

x58 - is this 58 hexa?

As an example,

*vaddps ymm0 ymm1 ymm3*
I was expecting:

*C5F458C3*
