[Bug c++/33661] template methods forget explicit local reg vars

["pinskia at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

------- Comment #1 from pinskia at gcc dot gnu dot org  2007-12-10 01:55 -------
Confirmed,
It also fails with 3.3 so this is not a regression.
A testcase for PPC:
template<class T>
class Tpl
{
public:
        static long* MySysCall()
        {
                register long retval __asm__("r3");

                asm
                (
                        "trap   #0\n\t"
                        "move.l %0,%0\n\t"
                : "=r"(retval)
                :
                : "r4"
                );

                return (long*)retval;
        }
};

void f()
{
        long* p = Tpl<char>::MySysCall();
        *p = 1;
}

Note I did not change the inline-asm's string though so it will not assemble.
