------- Comment #4 from steven at gcc dot gnu dot org 2006-01-07 18:04 -------
On AMD64 with GNU C version 4.2.0 20060107, I get this .optimized dump:
;; Function foo (foo)
foo (r)
{
int r$b;
int r$a;
char r$d;
<bb 2>:
r$b = r.b;
r$a = r.a;
r$d = r.d;
<retval>.m = r.m;
<retval>.b = r$b;
<retval>.a = r$a;
<retval>.d = r$d;
return <retval>;
}
