--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed, a slightly better testcase which causes the ICE with the C front=
-end
also (the C++ front-end inserts the __builtin_unreachable there) and should=
 be
able to compile on all targets:

int f (int a)
{
  asm (" " : "=3DX" (a) : : "memory");
  if (a)
    return 0;
  __builtin_unreachable();
