| 22 | /* Brief vocabulary: | |||
| 23 | ODR = One Definition Rule | |||
| 24 | In short, the ODR states that: | |||
| 25 | 1 In any translation unit, a template, type, function, or object can | |||
| 26 | have no more than one definition. Some of these can have any number | |||
| 27 | of declarations. A definition provides an instance. | |||
| 28 | 2 In the entire program, an object or non-inline function cannot have | |||
| 29 | more than one definition; if an object or function is used, it must | |||
| 30 | have exactly one definition. You can declare an object or function | |||
| 31 | that is never used, in which case you don't have to provide | |||
| 32 | a definition. In no event can there be more than one definition. | |||
| 33 | 3 Some things, like types, templates, and extern inline functions, can | |||
| 34 | be defined in more than one translation unit. For a given entity, | |||
| 35 | each definition must be the same. Non-extern objects and functions | |||
| 36 | in different translation units are different entities, even if their | |||
| 37 | names and types are the same. | |||
| 38 | ||||
| 39 | OTR = OBJ_TYPE_REF | |||
| 40 | This is the Gimple representation of type information of a polymorphic call. | |||
| 41 | It contains two parameters: | |||
| 42 | otr_type is a type of class whose method is called. | |||
| 43 | otr_token is the index into virtual table where address is taken. | |||
| 44 | ||||
| 45 | BINFO | |||
| 46 | This is the type inheritance information attached to each tree | |||
| 47 | RECORD_TYPE by the C++ frontend. It provides information about base | |||
| 48 | types and virtual tables. | |||
| 49 | ||||
| 50 | BINFO is linked to the RECORD_TYPE by TYPE_BINFO. | |||
| 51 | BINFO also links to its type by BINFO_TYPE and to the virtual table by | |||
| 52 | BINFO_VTABLE. | |||
| 53 | ||||
| 54 | Base types of a given type are enumerated by BINFO_BASE_BINFO | |||
| 55 | vector. Members of this vectors are not BINFOs associated | |||
| 56 | with a base type. Rather they are new copies of BINFOs | |||
| 57 | (base BINFOs). Their virtual tables may differ from | |||
| 58 | virtual table of the base type. Also BINFO_OFFSET specifies | |||
| 59 | offset of the base within the type. | |||
| 60 | ||||
| 61 | In the case of single inheritance, the virtual table is shared | |||
| 62 | and BINFO_VTABLE of base BINFO is NULL. In the case of multiple | |||
| 63 | inheritance the individual virtual tables are pointer to by | |||
| 64 | BINFO_VTABLE of base binfos (that differs of BINFO_VTABLE of | |||
| 65 | binfo associated to the base type). | |||
| 66 | ||||
| 67 | BINFO lookup for a given base type and offset can be done by | |||
| 68 | get_binfo_at_offset. It returns proper BINFO whose virtual table | |||
| 69 | can be used for lookup of virtual methods associated with the | |||
| 70 | base type. | |||
| 71 | ||||
| 72 | token | |||
| 73 | This is an index of virtual method in virtual table associated | |||
| 74 | to the type defining it. Token can be looked up from OBJ_TYPE_REF | |||
| 75 | or from DECL_VINDEX of a given virtual table. | |||
| 76 | ||||
| 77 | polymorphic (indirect) call | |||
| 78 | This is callgraph representation of virtual method call. Every | |||
| 79 | polymorphic call contains otr_type and otr_token taken from | |||
| 80 | original OBJ_TYPE_REF at callgraph construction time. | |||
| 81 | ||||
| 82 | What we do here: | |||
| 83 | ||||
| 84 | build_type_inheritance_graph triggers a construction of the type inheritance | |||
| 85 | graph. | |||
| 86 | ||||
| 87 | We reconstruct it based on types of methods we see in the unit. | |||
| 88 | This means that the graph is not complete. Types with no methods are not | |||
| 89 | inserted into the graph. Also types without virtual methods are not | |||
| 90 | represented at all, though it may be easy to add this. | |||
| 91 | ||||
| 92 | The inheritance graph is represented as follows: | |||
| 93 | ||||
| 94 | Vertices are structures odr_type. Every odr_type may correspond | |||
| 95 | to one or more tree type nodes that are equivalent by ODR rule. | |||
| 96 | (the multiple type nodes appear only with linktime optimization) | |||
| 97 | ||||
| 98 | Edges are represented by odr_type->base and odr_type->derived_types. | |||
| 99 | At the moment we do not track offsets of types for multiple inheritance. | |||
| 100 | Adding this is easy. | |||
| 101 | ||||
| 102 | possible_polymorphic_call_targets returns, given an parameters found in | |||
| 103 | indirect polymorphic edge all possible polymorphic call targets of the call. | |||
| 104 | ||||
| 105 | pass_ipa_devirt performs simple speculative devirtualization. | |||
