Thank you for the answer.
My question here was not about compilers. It was about assembler syntax. I
have reached the point where I am changing the machine description to handle
Synthetic registers. NASM requires a "byte" modifier in this instance, and
it has been so long since I used the Borland Turbo Assembler on a 486, that I
thought it prudent to check. ( There does not seem to be a manual for gas).
