124 | Usage of language-independent fields in a language-dependent manner: | |
911a71a7 | 125 | |
7ddedda4 MM |
126 | TYPE_ALIAS_SET |
127 | This field is used by TYPENAME_TYPEs, TEMPLATE_TYPE_PARMs, and so | |
128 | forth as a substitute for the mark bits provided in `lang_type'. | |
129 | At present, only the six low-order bits are used. | |
130 | ||
95b4aca6 | 131 | TYPE_LANG_SLOT_1 |
7ddedda4 | 132 | For an ENUMERAL_TYPE, this is ENUM_TEMPLATE_INFO. |
6d0a3f67 | 133 | For a FUNCTION_TYPE or METHOD_TYPE, this is TYPE_RAISES_EXCEPTIONS |
0aafb128 | 134 | |
9df2c88c | 135 | BINFO_VIRTUALS |
bb5e8a7f MM |
136 | For a binfo, this is a TREE_LIST. There is an entry for each |
137 | virtual function declared either in BINFO or its direct and | |
138 | indirect primary bases. | |
139 | ||
140 | The BV_DELTA of each node gives the amount by which to adjust the | |
141 | `this' pointer when calling the function. If the method is an | |
4639c5c6 | 142 | overridden version of a base class method, then it is assumed |
bb5e8a7f MM |
143 | that, prior to adjustment, the this pointer points to an object |
144 | of the base class. | |
174eceea | 145 | |
5e19c053 | 146 | The BV_VCALL_INDEX of each node, if non-NULL, gives the vtable |
19114537 | 147 | index of the vcall offset for this entry. |
c0bbf652 | 148 | |
5e19c053 | 149 | The BV_FN is the declaration for the virtual function itself. |
5e19c053 | 150 | |
c35cce41 | 151 | BINFO_VTABLE |
3461fba7 | 152 | This is an expression with POINTER_TYPE that gives the value |
c35cce41 | 153 | to which the vptr should be initialized. Use get_vtbl_decl_for_binfo |
3461fba7 | 154 | to extract the VAR_DECL for the complete vtable. |
c35cce41 | 155 | |
0fa5e05c | 156 | DECL_ARGUMENTS |
bb20cc46 | 157 | For a VAR_DECL this is DECL_ANON_UNION_ELEMS. |
051e6fd7 MM |
158 | |
159 | DECL_VINDEX | |
160 | This field is NULL for a non-virtual function. For a virtual | |
161 | function, it is eventually set to an INTEGER_CST indicating the | |
162 | index in the vtable at which this function can be found. When | |
163 | a virtual function is declared, but before it is known what | |
4639c5c6 | 164 | function is overridden, this field is the error_mark_node. |
051e6fd7 | 165 | |
bb20cc46 | 166 | Temporarily, it may be set to a TREE_LIST whose TREE_VALUE is |
051e6fd7 MM |
167 | the virtual function this one overrides, and whose TREE_CHAIN is |
168 | the old DECL_VINDEX. */ | |

3238 | DECL_INITIAL, which is always an ADDR_EXPR whose operand is a | |
4977bab6 ZW |
3239 | FUNCTION_DECL. The job of the thunk is to either adjust the this |
3240 | pointer before transferring control to the FUNCTION_DECL, or call | |
3241 | FUNCTION_DECL and then adjust the result value. Note, the result | |
3242 | pointer adjusting thunk must perform a call to the thunked | |
3243 | function, (or be implemented via passing some invisible parameter | |
3244 | to the thunked function, which is modified to perform the | |
3245 | adjustment just before returning). | |
19114537 | 3246 | |
eb68cb58 MM |
3247 | A thunk may perform either, or both, of the following operations: |
3248 | ||
4977bab6 ZW |

3252 | ||
4977bab6 ZW |
3253 | A this pointer adjusting thunk converts from a base to a derived |
3254 | class, and hence adds the offsets. A result pointer adjusting thunk | |
3255 | converts from a derived class to a base, and hence subtracts the | |
3256 | offsets. If both operations are performed, then the constant | |
34cd5ae7 | 3257 | adjustment is performed first for this pointer adjustment and last |
4977bab6 | 3258 | for the result pointer adjustment. |
eb68cb58 | 3259 | |
4977bab6 | 3260 | The constant adjustment is given by THUNK_FIXED_OFFSET. If the |

3261 | vcall or vbase offset is required, THUNK_VIRTUAL_OFFSET is |
