[Bug c/29305] New: local label-as-value being placed before function prolog

[jeremy at goop dot org]

In this code:

static void *bof;
int foo()
{
        __label__ boo;
  boo: bar();

        bof = &&boo;
}

the label "boo" is emitted as .L2, but it is being placed before the function
prologue:

foo:
.L2:
        pushl   %ebp
        movl    %esp, %ebp
        subl    $8, %esp
        call    bar
        movl    $.L2, bof
        leave
        ret


 If I add a goto to the label, it is placed correctly:
static void *bof;
int foo()
{
        __label__ boo;

  boo:  bar();

        bof = &&boo;
        goto boo;
}

foo:
        pushl   %ebp
        movl    %esp, %ebp
        subl    $8, %esp
.L3:
        call    bar
        movl    $.L3, bof
        jmp     .L3
