[Bug tree-optimization/24309] [4.1 Regression] ICE with -O3 -ftree-loop-linear

[pinskia at gcc dot gnu dot org]

------- Comment #2 from pinskia at gcc dot gnu dot org  2005-10-11 14:48 -------
Confirmed, reduced testcase:
float weight[10];
void lsp_weight_quant(float *x, char *cdbk)
{
   int i,j;
   float dist;
   int best_id=0;
   for (i=0;i<16;i++)
   {
      for (j=0;j<10;j++)
         dist=dist+weight[j];
      if (dist<0)
         best_id=i;
   }
   x[j] = cdbk[best_id*10+j];
}

------
but this is just a latent bug as the above also ICEs in 4.0.0.
Related to PR 23820.
