[Bug middle-end/30848] New: [4.1/4.2/4.3 regression] ICE with invalid constraint in asm statement

[reichelt at gcc dot gnu dot org]

The following invalid code snippet triggers an ICE since GCC 3.0
(with the exception of GCC 3.4.4 - 3.4.6):

=====================================
void foo(double d)
{
  __asm__ ("" : "=u" (d));
}
=====================================

bug.c: In function 'foo':
bug.c:3: error: output regs must be grouped at top of stack
bug.c:4: internal compiler error: in emit_swap_insn, at reg-stack.c:818
Please submit a full bug report, [etc.]

This is an x86 specific inline-asm bug really as the "u" constraint is x86
specific.
