118 | |
119 | Usage of language-independent fields in a language-dependent manner: | |
911a71a7 | 120 | |
7ddedda4 MM |
121 | TYPE_ALIAS_SET |
122 | This field is used by TYPENAME_TYPEs, TEMPLATE_TYPE_PARMs, and so | |
123 | forth as a substitute for the mark bits provided in `lang_type'. | |
124 | At present, only the six low-order bits are used. | |
125 | ||
95b4aca6 | 126 | TYPE_LANG_SLOT_1 |
7ddedda4 | 127 | For an ENUMERAL_TYPE, this is ENUM_TEMPLATE_INFO. |
6d0a3f67 | 128 | For a FUNCTION_TYPE or METHOD_TYPE, this is TYPE_RAISES_EXCEPTIONS |
0aafb128 | 129 | |
9df2c88c | 130 | BINFO_VIRTUALS |
bb5e8a7f MM |
131 | For a binfo, this is a TREE_LIST. There is an entry for each |
132 | virtual function declared either in BINFO or its direct and | |
133 | indirect primary bases. | |
134 | ||
135 | The BV_DELTA of each node gives the amount by which to adjust the | |
136 | `this' pointer when calling the function. If the method is an | |
4639c5c6 | 137 | overridden version of a base class method, then it is assumed |
bb5e8a7f MM |
138 | that, prior to adjustment, the this pointer points to an object |
139 | of the base class. | |
174eceea | 140 | |
5e19c053 | 141 | The BV_VCALL_INDEX of each node, if non-NULL, gives the vtable |
19114537 | 142 | index of the vcall offset for this entry. |
c0bbf652 | 143 | |
5e19c053 | 144 | The BV_FN is the declaration for the virtual function itself. |
5e19c053 | 145 | |
c35cce41 | 146 | BINFO_VTABLE |
3461fba7 | 147 | This is an expression with POINTER_TYPE that gives the value |
c35cce41 | 148 | to which the vptr should be initialized. Use get_vtbl_decl_for_binfo |
3461fba7 | 149 | to extract the VAR_DECL for the complete vtable. |
c35cce41 | 150 | |
0fa5e05c | 151 | DECL_ARGUMENTS |
bb20cc46 | 152 | For a VAR_DECL this is DECL_ANON_UNION_ELEMS. |
051e6fd7 MM |
153 | |
154 | DECL_VINDEX | |
155 | This field is NULL for a non-virtual function. For a virtual | |
156 | function, it is eventually set to an INTEGER_CST indicating the | |
157 | index in the vtable at which this function can be found. When | |
158 | a virtual function is declared, but before it is known what | |
4639c5c6 | 159 | function is overridden, this field is the error_mark_node. |
051e6fd7 | 160 | |
bb20cc46 | 161 | Temporarily, it may be set to a TREE_LIST whose TREE_VALUE is |
051e6fd7 MM |
162 | the virtual function this one overrides, and whose TREE_CHAIN is |
163 | the old DECL_VINDEX. */ | |

2946 | /* A thunk is a stub function. |
2947 | ||
2948 | A thunk is an alternate entry point for an ordinary FUNCTION_DECL. | |
2949 | The address of the ordinary FUNCTION_DECL is given by the | |
2950 | DECL_INITIAL, which is always an ADDR_EXPR whose operand is a | |
4977bab6 ZW |
2951 | FUNCTION_DECL. The job of the thunk is to either adjust the this |
2952 | pointer before transferring control to the FUNCTION_DECL, or call | |
2953 | FUNCTION_DECL and then adjust the result value. Note, the result | |
2954 | pointer adjusting thunk must perform a call to the thunked | |
2955 | function, (or be implemented via passing some invisible parameter | |
2956 | to the thunked function, which is modified to perform the | |
2957 | adjustment just before returning). | |
19114537 | 2958 | |
eb68cb58 MM |
2959 | A thunk may perform either, or both, of the following operations: |
2960 | ||
4977bab6 ZW |
2961 | o Adjust the this or result pointer by a constant offset. |
2962 | o Adjust the this or result pointer by looking up a vcall or vbase offset | |
eb68cb58 MM |
2963 | in the vtable. |
2964 | ||
4977bab6 ZW |
2965 | A this pointer adjusting thunk converts from a base to a derived |
2966 | class, and hence adds the offsets. A result pointer adjusting thunk | |
2967 | converts from a derived class to a base, and hence subtracts the | |
2968 | offsets. If both operations are performed, then the constant | |
34cd5ae7 | 2969 | adjustment is performed first for this pointer adjustment and last |
4977bab6 | 2970 | for the result pointer adjustment. |
eb68cb58 | 2971 | |
4977bab6 | 2972 | The constant adjustment is given by THUNK_FIXED_OFFSET. If the |
e00853fd NS |
2973 | vcall or vbase offset is required, THUNK_VIRTUAL_OFFSET is |
2974 | used. For this pointer adjusting thunks, it is the vcall offset | |
2975 | into the vtable. For result pointer adjusting thunks it is the | |
2976 | binfo of the virtual base to convert to. Use that binfo's vbase | |
2977 | offset. | |
2978 | ||
2979 | It is possible to have equivalent covariant thunks. These are | |
2980 | distinct virtual covariant thunks whose vbase offsets happen to | |
2981 | have the same value. THUNK_ALIAS is used to pick one as the | |
2982 | canonical thunk, which will get all the this pointer adjusting | |
2983 | thunks attached to it. */ | |
