And generate 'mov eax,op' or 'movzx eax,op'?

As a pseudo-instruction replacement for mov or as part of a larger macro? It's not really deterministic but you can at least use these constructs:

Code:

macro my_mov dreg,sreg
{
; ...
if dreg in <eax,ebx,...,esp>
; Destination is 32bit...
end if

;...

if sreg eqtype [eax];???
; Pointer
end if
; ...
}

xRom,

Preprocessor can be used to handle that particular issue. match is powerful, yeah. Wink

It's part of macro. I'm get value from memory and it can be byte, word, etc...
