2743 | ||
2744 | This basically works as follows: When we find a function | |
2745 | symbol (N_FUNC with a 'f' or 'F' in the symbol name), we record | |
2746 | a pointer to its type in the global in_function_type. Every | |

2748 | this procedure adds the name and type of that parameter | |

2750 | to in_function_type if it was called correctly). | |
2751 | ||
2752 | Note that since we are modifying a type, the result of | |
51b57ded | 2753 | lookup_function_type() should be memcpy()ed before calling |
997a978c JG |

2755 | evaluator can choose to ignore this. | |
