Hi
Today I tried this line:

Code Select
movzx rax, dh

and got the following error message

QuoteError A2256: Registers AH-DH may not be used with SPL-DIL or R8-R15

which is a bit misleading because rax is used here. yasm gives the error message:

Quoteerror: cannot use A/B/C/DH with instruction needing REX

which seems to be more appropriate...
