121 | Usage of language-independent fields in a language-dependent manner: | |
911a71a7 | 122 | |
7ddedda4 MM |
123 | TYPE_ALIAS_SET |
124 | This field is used by TYPENAME_TYPEs, TEMPLATE_TYPE_PARMs, and so | |
125 | forth as a substitute for the mark bits provided in `lang_type'. | |
126 | At present, only the six low-order bits are used. | |
127 | ||
95b4aca6 | 128 | TYPE_LANG_SLOT_1 |
7ddedda4 | 129 | For an ENUMERAL_TYPE, this is ENUM_TEMPLATE_INFO. |
6d0a3f67 | 130 | For a FUNCTION_TYPE or METHOD_TYPE, this is TYPE_RAISES_EXCEPTIONS |
0aafb128 | 131 | |
9df2c88c | 132 | BINFO_VIRTUALS |
bb5e8a7f MM |
133 | For a binfo, this is a TREE_LIST. There is an entry for each |
134 | virtual function declared either in BINFO or its direct and | |
135 | indirect primary bases. | |
136 | ||
137 | The BV_DELTA of each node gives the amount by which to adjust the | |
138 | `this' pointer when calling the function. If the method is an | |
4639c5c6 | 139 | overridden version of a base class method, then it is assumed |
bb5e8a7f MM |
140 | that, prior to adjustment, the this pointer points to an object |
141 | of the base class. | |
174eceea | 142 | |
5e19c053 | 143 | The BV_VCALL_INDEX of each node, if non-NULL, gives the vtable |
19114537 | 144 | index of the vcall offset for this entry. |
c0bbf652 | 145 | |
5e19c053 | 146 | The BV_FN is the declaration for the virtual function itself. |
5e19c053 | 147 | |
c35cce41 | 148 | BINFO_VTABLE |
3461fba7 | 149 | This is an expression with POINTER_TYPE that gives the value |
c35cce41 | 150 | to which the vptr should be initialized. Use get_vtbl_decl_for_binfo |
3461fba7 | 151 | to extract the VAR_DECL for the complete vtable. |
c35cce41 | 152 | |
0fa5e05c | 153 | DECL_ARGUMENTS |
bb20cc46 | 154 | For a VAR_DECL this is DECL_ANON_UNION_ELEMS. |
051e6fd7 MM |
155 | |
156 | DECL_VINDEX | |
157 | This field is NULL for a non-virtual function. For a virtual | |
158 | function, it is eventually set to an INTEGER_CST indicating the | |
159 | index in the vtable at which this function can be found. When | |
160 | a virtual function is declared, but before it is known what | |
4639c5c6 | 161 | function is overridden, this field is the error_mark_node. |
051e6fd7 | 162 | |
bb20cc46 | 163 | Temporarily, it may be set to a TREE_LIST whose TREE_VALUE is |
051e6fd7 MM |
164 | the virtual function this one overrides, and whose TREE_CHAIN is |
165 | the old DECL_VINDEX. */ | |

3215 | DECL_INITIAL, which is always an ADDR_EXPR whose operand is a | |
4977bab6 ZW |
3216 | FUNCTION_DECL. The job of the thunk is to either adjust the this |
3217 | pointer before transferring control to the FUNCTION_DECL, or call | |
3218 | FUNCTION_DECL and then adjust the result value. Note, the result | |
3219 | pointer adjusting thunk must perform a call to the thunked | |
3220 | function, (or be implemented via passing some invisible parameter | |
3221 | to the thunked function, which is modified to perform the | |
3222 | adjustment just before returning). | |
19114537 | 3223 | |
eb68cb58 MM |
3224 | A thunk may perform either, or both, of the following operations: |
3225 | ||
4977bab6 ZW |

3229 | ||
4977bab6 ZW |
3230 | A this pointer adjusting thunk converts from a base to a derived |
3231 | class, and hence adds the offsets. A result pointer adjusting thunk | |
3232 | converts from a derived class to a base, and hence subtracts the | |
3233 | offsets. If both operations are performed, then the constant | |
34cd5ae7 | 3234 | adjustment is performed first for this pointer adjustment and last |
4977bab6 | 3235 | for the result pointer adjustment. |
eb68cb58 | 3236 | |
4977bab6 | 3237 | The constant adjustment is given by THUNK_FIXED_OFFSET. If the |

3238 | vcall or vbase offset is required, THUNK_VIRTUAL_OFFSET is |

3241 | binfo of the virtual base to convert to. Use that binfo's vbase | |
3242 | offset. | |

3244 | It is possible to have equivalent covariant thunks. These are | |
