104 | |
105 | Usage of language-independent fields in a language-dependent manner: | |
911a71a7 MM |
106 | |
107 | TREE_USED | |
108 | This field is BINFO_INDIRECT_PRIMARY_P in a BINFO. | |
109 | ||
7ddedda4 MM |
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 | ||
115 | TYPE_BINFO | |
116 | For an ENUMERAL_TYPE, this is ENUM_TEMPLATE_INFO. | |
117 | For a TYPENAME_TYPE, this is TYPENAME_TYPE_FULLNAME. | |
bb20cc46 | 118 | For a TEMPLATE_TEMPLATE_PARM or BOUND_TEMPLATE_TEMPLATE_PARM, |
a1281f45 | 119 | this is TEMPLATE_TEMPLATE_PARM_TEMPLATE_INFO. |
0aafb128 | 120 | |
9df2c88c | 121 | BINFO_VIRTUALS |
5e19c053 | 122 | For a binfo, this is a TREE_LIST. The BV_DELTA of each node |
83f2ccf4 | 123 | gives the amount by which to adjust the `this' pointer when |
174eceea MM |
124 | calling the function. If the method is an overriden version of a |
125 | base class method, then it is assumed that, prior to adjustment, | |
126 | the this pointer points to an object of the base class. | |
127 | ||
5e19c053 | 128 | The BV_VCALL_INDEX of each node, if non-NULL, gives the vtable |
31f8e4f3 MM |
129 | index of the vcall offset for this entry. If |
130 | BV_USE_VCALL_INDEX_P then the corresponding vtable entry should | |
131 | use a virtual thunk, as opposed to an ordinary thunk. | |
c0bbf652 | 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 |
bb20cc46 | 149 | For a VAR_DECL this is DECL_ANON_UNION_ELEMS. |
051e6fd7 MM |
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 | ||
bb20cc46 | 158 | Temporarily, it may be set to a TREE_LIST whose TREE_VALUE is |
051e6fd7 MM |
159 | the virtual function this one overrides, and whose TREE_CHAIN is |
160 | the old DECL_VINDEX. */ | |

2617 | ||
2618 | where P is a POINTER_TYPE to a METHOD_TYPE appropriate for the | |
2619 | pointer to member. The fields are used as follows: | |
2620 | ||
2621 | If __INDEX is -1, then the function to call is non-virtual, and | |
2622 | is located at the address given by __PFN. | |
2623 | ||
2624 | If __INDEX is zero, then this a NULL pointer-to-member. | |
2625 | ||
2626 | Otherwise, the function to call is virtual. Then, __DELTA2 gives | |
2627 | the offset from an instance of the object to the virtual function | |
2628 | table, and __INDEX - 1 is the index into the vtable to use to | |
2629 | find the function. | |
2630 | ||
2631 | The value to use for the THIS parameter is the address of the | |
2632 | object plus __DELTA. | |
2633 | ||
2634 | For example, given: | |
2635 | ||
2636 | struct B1 { | |
2637 | int i; | |
2638 | }; | |
2639 | ||
2640 | struct B2 { | |

2642 | void f(); | |
2643 | }; | |
2644 | ||
2645 | struct S : public B1, B2 {}; | |
2646 | ||
2647 | the pointer-to-member for `&S::f' looks like: | |
2648 | ||
2649 | { 4, -1, { &f__2B2 } }; | |
2650 | ||
2651 | The `4' means that given an `S*' you have to add 4 bytes to get to | |
2652 | the address of the `B2*'. Then, the -1 indicates that this is a | |
2653 | non-virtual function. Of course, `&f__2B2' is the name of that | |
2654 | function. | |

2666 | (We don't need DELTA2, because the vtable is always the first thing | |
