  $ cat t.c
  int a[][1];
  int b, c, d;
  int *e, *f, *g;
  int h[4];
  void i() {
    int j, k, l;
    e = a[b];
    g = h;
    long m = e[1] * f[63];
    l = m >> c;
    g[32] = l;
    m = e[33] * f[62];
    k = m >> c;
    g[33] = k;
    m = e[7] * f[61];
    j = m >> c;
    g[34] = j;
    m = e[49] * f[60];
    d = m >> c;
    g[35] = d;
  }
