Usage of language-independent fields in a language-dependent manner: TYPE_ALIAS_SET This field is used by TYPENAME_TYPEs, TEMPLATE_TYPE_PARMs, and so forth as a substitute for the mark bits provided in `lang_type'. At present, only the six low-order bits are used. TYPE_BINFO For an ENUMERAL_TYPE, this is ENUM_TEMPLATE_INFO. For a TYPENAME_TYPE, this is TYPENAME_TYPE_FULLNAME. For a TEMPLATE_TEMPLATE_PARM, this is TEMPLATE_TEMPLATE_PARM_TEMPLATE_INFO. DECL_SAVED_INSNS/DECL_FIELD_SIZE For a static VAR_DECL, this is DECL_INIT_PRIORITY. BINFO_VIRTUALS For a binfo, this is a TREE_LIST. The BV_DELTA of each node gives the amount by which to adjust the `this' pointer when calling the function. If the method is an overriden version of a base class method, then it is assumed that, prior to adjustment, the this pointer points to an object of the base class. The BV_VCALL_INDEX of each node, if non-NULL, gives the vtable index of the vcall offset for this entry. The BV_FN is the declaration for the virtual function itself. When CLASSTYPE_COM_INTERFACE_P does not hold, the first entry does not have a BV_FN; it is just an offset. The BV_OVERRIDING_BASE is the binfo for the final overrider for this function. (This binfo's BINFO_TYPE will always be the same as the DECL_CLASS_CONTEXT for the function.) DECL_ARGUMENTS For a VAR_DECL this is DECL_ANON_UNION_ELEMS. DECL_VINDEX This field is NULL for a non-virtual function. For a virtual function, it is eventually set to an INTEGER_CST indicating the index in the vtable at which this function can be found. When a virtual function is declared, but before it is known what function is overriden, this field is the error_mark_node. Temporarily, it may be set to a TREE_LIST whose TREE_VALUE is the virtual function this one overrides, and whose TREE_CHAIN is the old DECL_VINDEX. */ /* Language-specific tree checkers. */ #if defined ENABLE_TREE_CHECKING && (GCC_VERSION >= 2007) #define VAR_OR_FUNCTION_DECL_CHECK(NODE) \ ({ const tree __t = NODE; \ enum tree_code __c = TREE_CODE(__t); \ if (__c != VAR_DECL && __c != FUNCTION_DECL) \ tree_check_failed (__t, VAR_DECL, __FILE__, \ __LINE__, __PRETTY_FUNCTION__); \ __t; }) #define VAR_FUNCTION_OR_PARM_DECL_CHECK(NODE) \ ({ const tree __t = NODE; \ enum tree_code __c = TREE_CODE(__t); \ if (__c != VAR_DECL \ && __c != FUNCTION_DECL \ && __c != PARM_DECL) \ tree_check_failed (__t, VAR_DECL, __FILE__, \ __LINE__, __PRETTY_FUNCTION__); \ __t; }) #define VAR_TEMPL_TYPE_OR_FUNCTION_DECL_CHECK(NODE) \ ({ const tree __t = NODE; \ enum tree_code __c = TREE_CODE(__t); \ if (__c != VAR_DECL \ && __c != FUNCTION_DECL \ && __c != TYPE_DECL \ && __c != TEMPLATE_DECL) \ tree_check_failed (__t, VAR_DECL, __FILE__, \ __LINE__, __PRETTY_FUNCTION__); \ __t; }) #define RECORD_OR_UNION_TYPE_CHECK(NODE) \ ({ const tree __t = NODE; \ enum tree_code __c = TREE_CODE(__t); \ if (__c != RECORD_TYPE && __c != UNION_TYPE) \ tree_check_failed (__t, RECORD_TYPE, __FILE__, \ __LINE__, __PRETTY_FUNCTION__); \ __t; }) #else /* not ENABLE_TREE_CHECKING, or not gcc */ #define VAR_OR_FUNCTION_DECL_CHECK(NODE) NODE #define VAR_FUNCTION_OR_PARM_DECL_CHECK(NODE) NODE #define VAR_TEMPL_TYPE_OR_FUNCTION_DECL_CHECK(NODE) NODE #define RECORD_OR_UNION_TYPE_CHECK(NODE) NODE #endif /* ABI control. */ /* Nonzero to enable experimental ABI changes. */ extern int flag_new_abi; /* Nonzero to use __cxa_atexit, rather than atexit, to register destructors for local statics and global objects. */ extern int flag_use_cxa_atexit; /* Nonzero to not ignore namespace std. */ extern int flag_honor_std; /* Nonzero means generate 'rtti' that give run-time type information. */ extern int flag_rtti; /* Nonzero if virtual base class offsets are stored in the virtual function table.

Otherwise, the function to call is virtual. Then, __DELTA2 gives the offset from an instance of the object to the virtual function table, and __INDEX - 1 is the index into the vtable to use to find the function. The value to use for the THIS parameter is the address of the object plus __DELTA. For example, given: struct B1 { int i; }; struct B2 { double d; void f(); }; struct S : public B1, B2 {}; the pointer-to-member for `&S::f' looks like: { 4, -1, { &f__2B2 } }; The `4' means that given an `S*' you have to add 4 bytes to get to the address of the `B2*'. Then, the -1 indicates that this is a non-virtual function. Of course, `&f__2B2' is the name of that function. (Of course, the exact values may differ depending on the mangling scheme, sizes of types, and such.).
