[Bug tree-optimization/33158] New: missed store sinking opportunity

[bonzini at gnu dot org]

In gcc.target/i386/cmov4.c no store sinking is performed for this code

  for (i = 0; i < ARCHnodes; i++) {
    nodekind[i] = (int) nodekindf[i];
    if (nodekind[i] == 3)
      nodekind[i] = 1;
  }

I would expect it to be rewritten as

  for (i = 0; i < ARCHnodes; i++) {
    int x = (int) nodekindf[i];
    if (x == 3)
      x = 1;
    nodekind[i] = x;
  }
