Cleaned up:
```
int a, f, g;
float b, c;
float *d, *e;
void l(int h) {
  for (; h; ++h) {
    float i = 0 * b, j = 0 * c;
    float *k = e;
    if (a) {
      k[0] = k[1] = (j - g * 0.5f) / 1;
      k[2] = (i + f * 0.5f) / 1;
      k[3] = (j + g * 0.5f) / 1;
    } else
      k[1] = f * 0.5f + g * 0.5f;
    d = e + 4;
    e = d;
  }
}
```
