Unable to decode VEX-prefixed AVX vpermq instruction
In what mode did you try to disassemble (16/32/64)?
32
What is the input buffer (binary stream) you used to reproduce the problem?
c4 e3 fd 00 ed 44
What is the expected output (or what instruction)?
vpermq ymm5, ymm5, 0x44
Which tool did you use to see the expected output?
ODA (online disassembler)
What do you see instead?
Distorm returns a decoding error. Stepping through the code it correctly
identifies it as a VEX-prefixed instruction, but the table lookup of the first
operand byte appears to fail.
What version of diStorm are you using? On what platform?
Using diStorm @ r229, the C API.

This instruction is in AVX2 set, and isn't implemented yet.

- Changed state: Accepted
It’s too hard to implement for outsiders.
