Good day!
Is there a way to verify expression correctness (in fasm 1)?
E.g. something like this:
Code:
macro mova x
{
  if correct <mov x,al>
    mov x,al
  else if correct <mov x,ax>
    mov x,ax
  else if correct <mov x,eax>
    mov x,eax
  else if correct <mov x,rax>
    mov x,rax
  end if
}    

It could be useful feature...

It can be used for many purposes.
E.g. to detect operand size: https://board.flatassembler.net/topic.php?p=204948

There is currently no such feature for this. But there are other ways to achieve your suggested example.

With match, although it is much more clumsy for what you want to do. You will need to match each syntax you want to support, and perhaps also set some internal flag to indicate successful assembly so that future blocks can be skipped.

In fasm 1 I think EQTYPE might be a better option to detect various syntactic variants.

qutype is good instrument but sometimes it needs to many lines of code to detect correctness of expression.
