The following input produces bad code; the `fintrz' insn is not emitted at
all.  It produces different, but equally bad, code with -O and without.

If the sequence `"f" "intrz" "%.x %1, %0"' is amalgomated into one string
`"fintrz%.x %1, %0"', or if `foo' is made non-`static', the problem goes away.

static inline double
foo(double value, double *iptr)
{
  double ipart;
  asm("f" "intrz" "%.x %1, %0" : "=f" (ipart) : "f" (value));
  *iptr = ipart;
  return(value - ipart);
}

double
bar(double value, double *iptr)
{
  return foo(value, iptr);
}
