101 | Usage of language-independent fields in a language-dependent manner: | |
102 | ||
103 | TYPE_ALIAS_SET | |
104 | This field is used by TYPENAME_TYPEs, TEMPLATE_TYPE_PARMs, and so | |
105 | forth as a substitute for the mark bits provided in `lang_type'. | |
106 | At present, only the six low-order bits are used. | |
107 | ||
108 | TYPE_BINFO | |
109 | For an ENUMERAL_TYPE, this is ENUM_TEMPLATE_INFO. | |
110 | For a TYPENAME_TYPE, this is TYPENAME_TYPE_FULLNAME. | |
111 | For a TEMPLATE_TEMPLATE_PARM, this is | |
112 | TEMPLATE_TEMPLATE_PARM_TEMPLATE_INFO. | |
0aafb128 MM |
113 | |
114 | DECL_SAVED_INSNS/DECL_FIELD_SIZE | |
115 | For a static VAR_DECL, this is DECL_INIT_PRIORITY. | |
83f2ccf4 MM |
116 | |
117 | BINFO_VIRTUALS | |
118 | For a binfo, this is a TREE_LIST. The TREE_PURPOSE of each node | |
119 | gives the amount by which to adjust the `this' pointer when | |
120 | calling the function. The TREE_VALUE is the declaration for the | |
121 | virtual function itself. When CLASSTYPE_COM_INTERFACE_P does not | |
122 | hold, the first entry does not have a TREE_VALUE; it is just an | |
0fa5e05c MM |
123 | offset. |
124 | ||
125 | DECL_ARGUMENTS | |
126 | For a VAR_DECL this is DECL_ANON_UNION_ELEMS. */ | |

2247 | where P is a POINTER_TYPE to a METHOD_TYPE appropriate for the | |

2249 | ||
2250 | If __INDEX is -1, then the function to call is non-virtual, and | |
2251 | is located at the address given by __PFN. | |
2252 | ||
2253 | If __INDEX is zero, then this a NULL pointer-to-member. | |
2254 | ||
2255 | Otherwise, the function to call is virtual. Then, __DELTA2 gives | |
2256 | the offset from an instance of the object to the virtual function | |
2257 | table, and __INDEX - 1 is the index into the vtable to use to | |
2258 | find the function. | |
2259 | ||
2260 | The value to use for the THIS parameter is the address of the | |
2261 | object plus __DELTA. | |

2264 | ||
2265 | struct B1 { | |

2269 | struct B2 { | |

2277 | ||
2278 | { 4, -1, { &f__2B2 } }; | |
2279 | ||
2280 | The `4' means that given an `S*' you have to add 4 bytes to get to | |
2281 | the address of the `B2*'. Then, the -1 indicates that this is a | |
2282 | non-virtual function. Of course, `&f__2B2' is the name of that | |
2283 | function. | |
