29.1.4 Precomputation and LHS terminals

On success, marpa_g_precompute() will sets and locks the terminal status of every symbol. More precisely, let the symbol be x, let the terminal status of x when marpa_g_precompute() was called be v_before, and let the terminal status of x when marpa_g_precompute() returns success be v_after. The effect of the successful call of marpa_g_precompute() will be as follows:

The terminal status of all symbols is locked after a successful call to marpa_g_precompute(). See marpa_g_precompute().
