This is as far as I can reduce it, -O1:
typedef union {
  unsigned a;
} l_fp;
int main(void)
{
  l_fp work;
  unsigned workUl_fXl_uf = 0xAAAAAAAA;
  int ndec = 10;
  do {
    ndec--;
    work.a = 0;
    work.a = 0;

    if (workUl_fXl_uf & 1)
      work.a ++;

    workUl_fXl_uf <<= 1;

    work.a ++;
    if (workUl_fXl_uf & 1)
      work.a ++;

    work.a ++;

    if (work.a > 4)
      abort ();
  }while(ndec > 0);
  return 0;
}
