------- Comment #4 from fxcoudert at gcc dot gnu dot org  2007-10-04 13:25 -------
We still have an ICE on __powitf2, at -O2 (but not -O1):

$ cat foo.i
typedef float TFtype __attribute__ ((mode (TF)));
TFtype __powitf2 (TFtype x, int m)
{
  TFtype y = x;
  while (m >>= 1)
    {
      x = x * x;
      if (m % 2)
        y = y * x;
    }
  return y;
}
$ cc1 -fpreprocessed foo.i -quiet -mabi=n32 -O2
foo.i: In function '__powitf2':
foo.i:12:1: error: insn does not satisfy its constraints:
(insn 12 11 40 5 foo.i:7 (set (reg:TF 46 $f14 [ x ])
        (reg:TF 44 $f12 [ x ])) 242 {*movtf_internal} (nil))
foo.i:12:1: internal compiler error: in reload_cse_simplify_operands, at
postreload.c:395
