[Bug middle-end/32680] fails to tailcall, useless stack adjustment

[rguenth at gcc dot gnu dot org]

------- Comment #4 from rguenth at gcc dot gnu dot org  2007-07-09 09:54 -------
So I just applied it and now we get

function1:
.LFB2:
        movl    $10, %eax
        ret

function2:
.LFB3:
        movq    pfunc(%rip), %r11
        jmp     *%r11

for the indirect call.  Fixed.
