or, and (||, &&) in ifidn macro

[nobody]

Hi,

Is there a way in nasm to use or/and in ifidn macro?

E.g.

%ifidn %1,rax || %1,rbx
     ....
%endif

Thanks,
Csaba

I don't think so (I'm not a very sophisticated macro user). I think you'll have to do:

%ifidn %1, rax
; some code
%endif
%ifidn %1, ebx
; same code
%endif

Nest 'em for "and", of course. You might want %ifidni to catch uppercase, too.

Best,
Frank

Thanks,

Actually I did what you have written but I was curious if it is possible to do it as in other languages (usually).

Thanks,

why not do like this

Code: [Select]

%macro some_macro
  ; some code
%endif

%ifidn this, that
  some_macro
%elsifidn other_this, other_that
  some macro
%endif
