107 | Usage of language-independent fields in a language-dependent manner: | |
911a71a7 MM |
108 | |
109 | TREE_USED | |
110 | This field is BINFO_INDIRECT_PRIMARY_P in a BINFO. | |
111 | ||
7ddedda4 MM |
112 | TYPE_ALIAS_SET |
113 | This field is used by TYPENAME_TYPEs, TEMPLATE_TYPE_PARMs, and so | |
114 | forth as a substitute for the mark bits provided in `lang_type'. | |
115 | At present, only the six low-order bits are used. | |
116 | ||
117 | TYPE_BINFO | |
118 | For an ENUMERAL_TYPE, this is ENUM_TEMPLATE_INFO. | |
6d0a3f67 | 119 | For a FUNCTION_TYPE or METHOD_TYPE, this is TYPE_RAISES_EXCEPTIONS |
0aafb128 | 120 | |
9df2c88c | 121 | BINFO_VIRTUALS |
bb5e8a7f MM |
122 | For a binfo, this is a TREE_LIST. There is an entry for each |
123 | virtual function declared either in BINFO or its direct and | |
124 | indirect primary bases. | |
125 | ||
126 | The BV_DELTA of each node gives the amount by which to adjust the | |
127 | `this' pointer when calling the function. If the method is an | |
4639c5c6 | 128 | overridden version of a base class method, then it is assumed |
bb5e8a7f MM |
129 | that, prior to adjustment, the this pointer points to an object |
130 | of the base class. | |
174eceea | 131 | |
5e19c053 | 132 | The BV_VCALL_INDEX of each node, if non-NULL, gives the vtable |
548502d3 | 133 | index of the vcall offset for this entry. |
c0bbf652 | 134 | |
5e19c053 | 135 | The BV_FN is the declaration for the virtual function itself. |
5e19c053 | 136 | |
c35cce41 | 137 | BINFO_VTABLE |
3461fba7 | 138 | This is an expression with POINTER_TYPE that gives the value |
c35cce41 | 139 | to which the vptr should be initialized. Use get_vtbl_decl_for_binfo |
3461fba7 | 140 | to extract the VAR_DECL for the complete vtable. |
c35cce41 | 141 | |
0fa5e05c | 142 | DECL_ARGUMENTS |
bb20cc46 | 143 | For a VAR_DECL this is DECL_ANON_UNION_ELEMS. |
051e6fd7 MM |
144 | |
145 | DECL_VINDEX | |
146 | This field is NULL for a non-virtual function. For a virtual | |
147 | function, it is eventually set to an INTEGER_CST indicating the | |
148 | index in the vtable at which this function can be found. When | |
149 | a virtual function is declared, but before it is known what | |
4639c5c6 | 150 | function is overridden, this field is the error_mark_node. |
051e6fd7 | 151 | |
bb20cc46 | 152 | Temporarily, it may be set to a TREE_LIST whose TREE_VALUE is |
051e6fd7 MM |
153 | the virtual function this one overrides, and whose TREE_CHAIN is |
154 | the old DECL_VINDEX. */ | |

2873 | pointer before transferring control to the FUNCTION_DECL, or call | |

2875 | pointer adjusting thunk must perform a call to the thunked | |
