 Hey!

I'd suggest you try this one:

 ,----
|  __asm__("pushl %0"
|          : /*No output*/
|          :"a"(ResultsMod));
 `----

You cannot rely on ResultsMod being stored in eax, and that would be
contrary to the idea behind the templated approach taken in arg0 of
__asm__.

So the snippet above means "no outputs; store ResultsMod into any
'a-register' (despite intel having only one) referenced as '%0'; push
the value contained in register ref'ed by '%0'".

   Hope that's kinda right,
