108 | Usage of language-independent fields in a language-dependent manner: | |
d0ceae4d | 109 | |
e4e283ec | 110 | TYPE_ALIAS_SET |
111 | This field is used by TYPENAME_TYPEs, TEMPLATE_TYPE_PARMs, and so | |
112 | forth as a substitute for the mark bits provided in `lang_type'. | |
113 | At present, only the six low-order bits are used. | |
114 | ||
3cb98335 | 115 | TYPE_LANG_SLOT_1 |
e4e283ec | 116 | For an ENUMERAL_TYPE, this is ENUM_TEMPLATE_INFO. |
8cbe13ee | 117 | For a FUNCTION_TYPE or METHOD_TYPE, this is TYPE_RAISES_EXCEPTIONS |
cec1f6a6 | 118 | |
ab7943b9 | 119 | BINFO_VIRTUALS |
641985fa | 120 | For a binfo, this is a TREE_LIST. There is an entry for each |
121 | virtual function declared either in BINFO or its direct and | |
122 | indirect primary bases. | |
123 | ||
124 | The BV_DELTA of each node gives the amount by which to adjust the | |
125 | `this' pointer when calling the function. If the method is an | |
e18c26dd | 126 | overridden version of a base class method, then it is assumed |
641985fa | 127 | that, prior to adjustment, the this pointer points to an object |
128 | of the base class. | |
8fcde9a9 | 129 | |
fc475736 | 130 | The BV_VCALL_INDEX of each node, if non-NULL, gives the vtable |
ac13e8d9 | 131 | index of the vcall offset for this entry. |
7b4abb45 | 132 | |
fc475736 | 133 | The BV_FN is the declaration for the virtual function itself. |
fc475736 | 134 | |
59751e6c | 135 | BINFO_VTABLE |
5ad590ad | 136 | This is an expression with POINTER_TYPE that gives the value |
59751e6c | 137 | to which the vptr should be initialized. Use get_vtbl_decl_for_binfo |
5ad590ad | 138 | to extract the VAR_DECL for the complete vtable. |
59751e6c | 139 | |
74c333de | 140 | DECL_ARGUMENTS |
50cd3f45 | 141 | For a VAR_DECL this is DECL_ANON_UNION_ELEMS. |
d0d8836b | 142 | |
143 | DECL_VINDEX | |
144 | This field is NULL for a non-virtual function. For a virtual | |
145 | function, it is eventually set to an INTEGER_CST indicating the | |
146 | index in the vtable at which this function can be found. When | |
147 | a virtual function is declared, but before it is known what | |
e18c26dd | 148 | function is overridden, this field is the error_mark_node. |
d0d8836b | 149 | |
50cd3f45 | 150 | Temporarily, it may be set to a TREE_LIST whose TREE_VALUE is |
d0d8836b | 151 | the virtual function this one overrides, and whose TREE_CHAIN is |
152 | the old DECL_VINDEX. */ | |

2795 | ||
2796 | A thunk is an alternate entry point for an ordinary FUNCTION_DECL. | |
2797 | The address of the ordinary FUNCTION_DECL is given by the | |
2798 | DECL_INITIAL, which is always an ADDR_EXPR whose operand is a | |
805e22b2 | 2799 | FUNCTION_DECL. The job of the thunk is to either adjust the this |
2800 | pointer before transferring control to the FUNCTION_DECL, or call | |
2801 | FUNCTION_DECL and then adjust the result value. Note, the result | |
2802 | pointer adjusting thunk must perform a call to the thunked | |
2803 | function, (or be implemented via passing some invisible parameter | |
2804 | to the thunked function, which is modified to perform the | |
2805 | adjustment just before returning). | |
ac13e8d9 | 2806 | |
a2697ab6 | 2807 | A thunk may perform either, or both, of the following operations: |
2808 | ||
805e22b2 | 2809 | o Adjust the this or result pointer by a constant offset. |
2810 | o Adjust the this or result pointer by looking up a vcall or vbase offset | |
a2697ab6 | 2811 | in the vtable. |
2812 | ||
805e22b2 | 2813 | A this pointer adjusting thunk converts from a base to a derived |
2814 | class, and hence adds the offsets. A result pointer adjusting thunk | |
2815 | converts from a derived class to a base, and hence subtracts the | |
2816 | offsets. If both operations are performed, then the constant | |
755edffd | 2817 | adjustment is performed first for this pointer adjustment and last |
805e22b2 | 2818 | for the result pointer adjustment. |
a2697ab6 | 2819 | |
805e22b2 | 2820 | The constant adjustment is given by THUNK_FIXED_OFFSET. If the |
6709b660 | 2821 | vcall or vbase offset is required, THUNK_VIRTUAL_OFFSET is |
2822 | used. For this pointer adjusting thunks, it is the vcall offset | |
2823 | into the vtable. For result pointer adjusting thunks it is the | |
2824 | binfo of the virtual base to convert to. Use that binfo's vbase | |
2825 | offset. | |
2826 | ||
2827 | It is possible to have equivalent covariant thunks. These are | |
2828 | distinct virtual covariant thunks whose vbase offsets happen to | |
