104 | Usage of language-independent fields in a language-dependent manner: | |
911a71a7 MM |
105 | |
106 | TREE_USED | |
107 | This field is BINFO_INDIRECT_PRIMARY_P in a BINFO. | |
108 | ||
7ddedda4 MM |
109 | TYPE_ALIAS_SET |
110 | This field is used by TYPENAME_TYPEs, TEMPLATE_TYPE_PARMs, and so | |
111 | forth as a substitute for the mark bits provided in `lang_type'. | |
112 | At present, only the six low-order bits are used. | |
113 | ||
114 | TYPE_BINFO | |
115 | For an ENUMERAL_TYPE, this is ENUM_TEMPLATE_INFO. | |
6d0a3f67 | 116 | For a FUNCTION_TYPE or METHOD_TYPE, this is TYPE_RAISES_EXCEPTIONS |
0aafb128 | 117 | |
9df2c88c | 118 | BINFO_VIRTUALS |
bb5e8a7f MM |
119 | For a binfo, this is a TREE_LIST. There is an entry for each |
120 | virtual function declared either in BINFO or its direct and | |
121 | indirect primary bases. | |
122 | ||
123 | The BV_DELTA of each node gives the amount by which to adjust the | |
124 | `this' pointer when calling the function. If the method is an | |
4639c5c6 | 125 | overridden version of a base class method, then it is assumed |
bb5e8a7f MM |
126 | that, prior to adjustment, the this pointer points to an object |
127 | of the base class. | |
174eceea | 128 | |
5e19c053 | 129 | The BV_VCALL_INDEX of each node, if non-NULL, gives the vtable |
548502d3 | 130 | index of the vcall offset for this entry. |
c0bbf652 | 131 | |
5e19c053 | 132 | The BV_FN is the declaration for the virtual function itself. |
5e19c053 | 133 | |
c35cce41 | 134 | BINFO_VTABLE |
3461fba7 | 135 | This is an expression with POINTER_TYPE that gives the value |
c35cce41 | 136 | to which the vptr should be initialized. Use get_vtbl_decl_for_binfo |
3461fba7 | 137 | to extract the VAR_DECL for the complete vtable. |
c35cce41 | 138 | |
0fa5e05c | 139 | DECL_ARGUMENTS |
bb20cc46 | 140 | For a VAR_DECL this is DECL_ANON_UNION_ELEMS. |
051e6fd7 MM |
141 | |
142 | DECL_VINDEX | |
143 | This field is NULL for a non-virtual function. For a virtual | |
144 | function, it is eventually set to an INTEGER_CST indicating the | |
145 | index in the vtable at which this function can be found. When | |
146 | a virtual function is declared, but before it is known what | |
4639c5c6 | 147 | function is overridden, this field is the error_mark_node. |
051e6fd7 | 148 | |
bb20cc46 | 149 | Temporarily, it may be set to a TREE_LIST whose TREE_VALUE is |
051e6fd7 MM |
150 | the virtual function this one overrides, and whose TREE_CHAIN is |
151 | the old DECL_VINDEX. */ | |

2827 | A thunk is an alternate entry point for an ordinary FUNCTION_DECL. | |

2829 | DECL_INITIAL, which is always an ADDR_EXPR whose operand is a | |
4977bab6 ZW |
2830 | FUNCTION_DECL. The job of the thunk is to either adjust the this |
2831 | pointer before transferring control to the FUNCTION_DECL, or call | |
2832 | FUNCTION_DECL and then adjust the result value. Note, the result | |
2833 | pointer adjusting thunk must perform a call to the thunked | |
2834 | function, (or be implemented via passing some invisible parameter | |
2835 | to the thunked function, which is modified to perform the | |
