Hi Uma,
Not all X86 vector instructions are implemented. What you're seeing is
that pmovzxbw isn't
implemented. Specifically, there's at least one version (as shown here
https://www.felixcloutier.com/x86/pmovzx) which hasn't been implemented
yet. I'm not sure which one. The `Vdq_Udq_or_Mq` somehow specifies the
sizes of the registers, but it's not documented and you'll have to dig into
the code to figure out how it works.
You can either compile your code with SSE4/AVX or you can implement the
instruction. If you do the latter, we would appreciate the contribution!
Cheers,
Jason
