--- Comment #7 from Alan Modra <amodra at gmail dot com> ---
Fixed on trunk.  The problem exists on gcc-6 since we have wrong "o"
constraints on lsxxp/stxssp there.  Triggered by:

float foo (void *p)
{
  register float f __asm__ ("v0");
  f = *(float *)((char *) p + 2);
  __asm__ ("#%0" : "+wa" (f));
  return f;
}
