[Bug tree-optimization/23049] [4.1 Regression] ICE with -O3 -ftree-vectorize on 4.1.x


------- Additional Comments From pinskia at gcc dot gnu dot org  2005-07-24 15:37 -------
Reduced testcase for the first one:
static unsigned short int crc_table[256];
void AC3_encode_init(void)
{
  unsigned int c, n, k;
  for(n=0;  n<256; n++)
  {
    c = n << 8;
    for (k = 0; k < 8; k++)
    {
      if (c & (1 << 15))
       c = ((c << 1) & 0xffff) ^ (((1 << 0) | (1 << 2) | (1 << 15) | (1 << 16)) & 0xffff);
    }
    crc_table[n] = c;
  }
}
