109 | |
110 | Usage of language-independent fields in a language-dependent manner: | |
111 | ||
112 | TYPE_ALIAS_SET | |
113 | This field is used by TYPENAME_TYPEs, TEMPLATE_TYPE_PARMs, and so | |
114 | forth as a substitute for the mark bits provided in `lang_type'. | |
115 | At present, only the six low-order bits are used. | |
116 | ||
117 | TYPE_BINFO | |
118 | For an ENUMERAL_TYPE, this is ENUM_TEMPLATE_INFO. | |
119 | For a TYPENAME_TYPE, this is TYPENAME_TYPE_FULLNAME. | |
120 | For a TEMPLATE_TEMPLATE_PARM, this is | |
121 | TEMPLATE_TEMPLATE_PARM_TEMPLATE_INFO. | |
0aafb128 | 122 | |
9df2c88c | 123 | BINFO_VIRTUALS |
5e19c053 | 124 | For a binfo, this is a TREE_LIST. The BV_DELTA of each node |
83f2ccf4 | 125 | gives the amount by which to adjust the `this' pointer when |
174eceea MM |
126 | calling the function. If the method is an overriden version of a |
127 | base class method, then it is assumed that, prior to adjustment, | |
128 | the this pointer points to an object of the base class. | |
129 | ||
5e19c053 | 130 | The BV_VCALL_INDEX of each node, if non-NULL, gives the vtable |
c0bbf652 MM |
131 | index of the vcall offset for this entry. |
132 | ||
5e19c053 | 133 | The BV_FN is the declaration for the virtual function itself. |
c0bbf652 | 134 | When CLASSTYPE_COM_INTERFACE_P does not hold, the first entry |
5e19c053 MM |
135 | does not have a BV_FN; it is just an offset. |
136 | ||
137 | The BV_OVERRIDING_BASE is the binfo for the final overrider for | |
138 | this function. (This binfo's BINFO_TYPE will always be the same | |
139 | as the DECL_CLASS_CONTEXT for the function.) | |
0fa5e05c | 140 | |
c35cce41 MM |
141 | BINFO_VTABLE |
142 | Sometimes this is a VAR_DECL. Under the new ABI, it is instead | |
143 | an expression with POINTER_TYPE pointing that gives the value | |
144 | to which the vptr should be initialized. Use get_vtbl_decl_for_binfo | |
145 | to extract the VAR_DECL for the complete vtable; that macro works | |
146 | in both ABIs. | |
147 | ||
0fa5e05c | 148 | DECL_ARGUMENTS |
051e6fd7 MM |
149 | For a VAR_DECL this is DECL_ANON_UNION_ELEMS. |
150 | ||
151 | DECL_VINDEX | |
152 | This field is NULL for a non-virtual function. For a virtual | |
153 | function, it is eventually set to an INTEGER_CST indicating the | |
154 | index in the vtable at which this function can be found. When | |
155 | a virtual function is declared, but before it is known what | |
156 | function is overriden, this field is the error_mark_node. | |
157 | ||
158 | Temporarily, it may be set to a TREE_LIST whose TREE_VALUE is | |
159 | the virtual function this one overrides, and whose TREE_CHAIN is | |
160 | the old DECL_VINDEX. */ | |

2724 | struct { | |
2725 | short __delta; | |
2726 | short __index; | |
2727 | union { | |

2729 | short __delta2; | |
2730 | } __pfn_or_delta2; | |
2731 | }; | |
2732 | ||
2733 | where P is a POINTER_TYPE to a METHOD_TYPE appropriate for the | |
2734 | pointer to member. The fields are used as follows: | |
2735 | ||
2736 | If __INDEX is -1, then the function to call is non-virtual, and | |
2737 | is located at the address given by __PFN. | |
2738 | ||
2739 | If __INDEX is zero, then this a NULL pointer-to-member. | |
2740 | ||
2741 | Otherwise, the function to call is virtual. Then, __DELTA2 gives | |
2742 | the offset from an instance of the object to the virtual function | |
2743 | table, and __INDEX - 1 is the index into the vtable to use to | |
2744 | find the function. | |
2745 | ||
2746 | The value to use for the THIS parameter is the address of the | |
2747 | object plus __DELTA. | |
2748 | ||
2749 | For example, given: | |
2750 | ||
2751 | struct B1 { | |
2752 | int i; | |
2753 | }; | |
2754 | ||
2755 | struct B2 { | |
2756 | double d; | |
2757 | void f(); | |
2758 | }; | |
2759 | ||
2760 | struct S : public B1, B2 {}; | |
2761 | ||
2762 | the pointer-to-member for `&S::f' looks like: | |
2763 | ||
2764 | { 4, -1, { &f__2B2 } }; | |
2765 | ||
2766 | The `4' means that given an `S*' you have to add 4 bytes to get to | |
2767 | the address of the `B2*'. Then, the -1 indicates that this is a | |
2768 | non-virtual function. Of course, `&f__2B2' is the name of that | |
2769 | function. | |
2770 | ||
adecb3f4 | 2771 | (Of course, the exact values may differ depending on the mangling |
c7e266a6 MM |
2772 | scheme, sizes of types, and such.). |
2773 | ||
2774 | Under the new ABI, we do: | |
2775 | ||
2776 | struct { | |
2777 | __P __pfn; | |
2778 | ptrdiff_t __delta; | |
2779 | }; | |
2780 | ||
2781 | (We don't need DELTA2, because the vtable is always the first thing | |
2782 | in the object.) If the function is virtual, then PFN is one plus | |
2783 | twice the index into the vtable; otherwise, it is just a pointer to | |
2784 | the function. */ | |
