------- Comment #12 from pinskia at gcc dot gnu dot org  2005-11-02 16:03 -------
Here is another more reduced testcase (still at -O1 -fno-tree-sra):
typedef struct {
  unsigned a;
} l_fp;
void dolfptoa(short ndec)
{
  l_fp work;
  unsigned workUl_fXl_uf;
  work.a = 0x535f3d8;
  while (ndec > 0) {

    ndec--;
    work.a = 0;
    work.a = 0;
    if (workUl_fXl_uf & 0x80000000)
      work.a |= 0x1;
    workUl_fXl_uf <<= 1;

    work.a <<= 1;
    if (workUl_fXl_uf & 0x80000000)
      work.a |= 0x1;
    workUl_fXl_uf <<= 1;

    work.a <<= 1;

    if (!(work.a < 10))
      abort ();
  }
}
int main()
{
  dolfptoa(6);
  return 0;
}
