We could also limit the number of iterations:
int i;
- for (i = 1; VEC_iterate (eh_landing_pad, cfun->eh->lp_array, i, lp); ++i)
+ int len = VEC_length (eh_landing_pad, cfun->eh->lp_array) * 2;
+ for (i = 1;
+ VEC_iterate (eh_landing_pad, cfun->eh->lp_array, i, lp) && i < len;
+ i++)
if (lp)
changed |= cleanup_empty_eh (lp);
