According to cagliostro:

Yes:  You can define a return value variable for the function:

    Function foo ( x, y: Integer ) = bar: Integer

    begin (* foo *)
      asm ( '  '
            : '=rm' ( bar )
	    : (* input *)
	    : (* clobbered *) );
    end (* foo *);

Even if you don't define one, you can use `Result' for this purpose:

    Function foo ( x, y: Integer ): Integer

    begin (* foo *)
      asm ( '  '
            : '=rm' ( Result )
	    : (* input *)
	    : (* clobbered *) );
    end (* foo *);

Hope this helps,
