Hi there,
I'm new here, please forgive me if I'm not posting precisely in the right place.

I was trying to use the vaesenc instruction (and others from the family) with fasm2, but I'm getting an error which is not just "illegal instruction" as if fasm2 didn't know it or I made a typo, what I'm getting is (full output):



It seems to me that this is a bug, but am I missing something?... I can use the usual AVX512 instructions for vectorized calculations with no problems, but never tried to use vaesenc. The basic aesenc (non VAES, non AVX512) instruction also assembles fine, but not this one.

I am testing with a one-line assembly file containing just "vaesenc zmm0, zmm1, zmm2"

Thanks in advance for any help!

Yes, it's a bug, thank you! The fix is uploaded.

Wow, that was fast! Thanks!
