The BV_DELTA of each node 12590075Sobrien gives the amount by which to adjust the `this' pointer when 12690075Sobrien calling the function. If the method is an overriden version of a 12790075Sobrien base class method, then it is assumed that, prior to adjustment, 12890075Sobrien the this pointer points to an object of the base class. 12950397Sobrien 13090075Sobrien The BV_VCALL_INDEX of each node, if non-NULL, gives the vtable 13190075Sobrien index of the vcall offset for this entry. If 13290075Sobrien BV_USE_VCALL_INDEX_P then the corresponding vtable entry should 13390075Sobrien use a virtual thunk, as opposed to an ordinary thunk. 13490075Sobrien 13590075Sobrien The BV_FN is the declaration for the virtual function itself. 13690075Sobrien 13790075Sobrien BINFO_VTABLE 13890075Sobrien This is an expression with POINTER_TYPE that gives the value 13990075Sobrien to which the vptr should be initialized. Use get_vtbl_decl_for_binfo 14090075Sobrien to extract the VAR_DECL for the complete vtable. 14190075Sobrien 14290075Sobrien DECL_ARGUMENTS 14390075Sobrien For a VAR_DECL this is DECL_ANON_UNION_ELEMS. 14490075Sobrien 14590075Sobrien DECL_VINDEX 14690075Sobrien This field is NULL for a non-virtual function. For a virtual 14790075Sobrien function, it is eventually set to an INTEGER_CST indicating the 14890075Sobrien index in the vtable at which this function can be found. When 14990075Sobrien a virtual function is declared, but before it is known what 15090075Sobrien function is overriden, this field is the error_mark_node. 15190075Sobrien 15290075Sobrien Temporarily, it may be set to a TREE_LIST whose TREE_VALUE is 15390075Sobrien the virtual function this one overrides, and whose TREE_CHAIN is 15490075Sobrien the old DECL_VINDEX. */ 15590075Sobrien 15690075Sobrien/* Language-specific tree checkers. */ 15790075Sobrien 15890075Sobrien#if defined ENABLE_TREE_CHECKING && (GCC_VERSION >= 2007) 15990075Sobrien 16090075Sobrien#define VAR_OR_FUNCTION_DECL_CHECK(NODE) \ 16190075Sobrien({ const tree __t = (NODE); \ 16290075Sobrien enum tree_code const __c = TREE_CODE(__t); \ 16390075Sobrien if (__c != VAR_DECL && __c != FUNCTION_DECL) \ 16490075Sobrien tree_check_failed (__t, VAR_DECL, __FILE__, __LINE__, \ 16590075Sobrien __FUNCTION__); \ 16690075Sobrien __t; }) 16790075Sobrien 16890075Sobrien#define VAR_FUNCTION_OR_PARM_DECL_CHECK(NODE) \ 16990075Sobrien({ const tree __t = (NODE); \ 17090075Sobrien enum tree_code const __c = TREE_CODE(__t); \ 17190075Sobrien if (__c != VAR_DECL \ 17290075Sobrien && __c != FUNCTION_DECL \ 17390075Sobrien && __c != PARM_DECL) \ 17490075Sobrien tree_check_failed (__t, VAR_DECL, __FILE__, __LINE__, \ 17590075Sobrien __FUNCTION__); \ 17690075Sobrien __t; }) 17790075Sobrien 17890075Sobrien#define VAR_TEMPL_TYPE_OR_FUNCTION_DECL_CHECK(NODE) \ 17990075Sobrien({ const tree __t = (NODE); \ 18090075Sobrien enum tree_code const __c = TREE_CODE(__t); \ 18190075Sobrien if (__c != VAR_DECL \ 18290075Sobrien && __c != FUNCTION_DECL \ 18390075Sobrien && __c != TYPE_DECL \ 18490075Sobrien && __c != TEMPLATE_DECL) \ 18590075Sobrien tree_check_failed (__t, VAR_DECL, __FILE__, __LINE__, \ 18690075Sobrien __FUNCTION__); \ 18790075Sobrien __t; }) 18890075Sobrien 18990075Sobrien#define RECORD_OR_UNION_TYPE_CHECK(NODE) \ 19090075Sobrien({ const tree __t = (NODE); \ 19190075Sobrien enum tree_code const __c = TREE_CODE(__t); \ 19290075Sobrien if (__c != RECORD_TYPE && __c != UNION_TYPE) \ 19390075Sobrien tree_check_failed (__t, RECORD_TYPE, __FILE__, __LINE__, \ 19490075Sobrien __FUNCTION__); \ 19590075Sobrien __t; }) 19690075Sobrien 19790075Sobrien#define BOUND_TEMPLATE_TEMPLATE_PARM_TYPE_CHECK(NODE) \ 19890075Sobrien({ const tree __t = (NODE); \ 19990075Sobrien enum tree_code const __c = TREE_CODE(__t); \ 20090075Sobrien if (__c != BOUND_TEMPLATE_TEMPLATE_PARM) \ 20190075Sobrien tree_check_failed (__t, BOUND_TEMPLATE_TEMPLATE_PARM, \ 20290075Sobrien __FILE__, __LINE__, __FUNCTION__); \ 20390075Sobrien __t; }) 20490075Sobrien 20590075Sobrien#else /* not ENABLE_TREE_CHECKING, or not gcc */ 20690075Sobrien 20790075Sobrien#define VAR_OR_FUNCTION_DECL_CHECK(NODE) (NODE) 20890075Sobrien#define VAR_FUNCTION_OR_PARM_DECL_CHECK(NODE) (NODE) 20990075Sobrien#define VAR_TEMPL_TYPE_OR_FUNCTION_DECL_CHECK(NODE) (NODE) 21090075Sobrien#define RECORD_OR_UNION_TYPE_CHECK(NODE) (NODE) 21190075Sobrien#define BOUND_TEMPLATE_TEMPLATE_PARM_TYPE_CHECK(NODE) (NODE) 21290075Sobrien 21390075Sobrien#endif 21490075Sobrien 21590075Sobrien 21690075Sobrien/* ABI control. */ 21790075Sobrien 21890075Sobrien/* Nonzero to use __cxa_atexit, rather than atexit, to register 21990075Sobrien destructors for local statics and global objects. */ 22090075Sobrien 22190075Sobrienextern int flag_use_cxa_atexit; 22290075Sobrien 22390075Sobrien/* Nonzero means generate 'rtti' that give run-time type information. */ 22490075Sobrien 22590075Sobrienextern int flag_rtti; 22690075Sobrien 22790075Sobrien/* Nonzero if we want to support huge (> 2^(sizeof(short)*8-1) bytes) 22890075Sobrien objects. */ 22990075Sobrien 23090075Sobrienextern int flag_huge_objects; 23190075Sobrien 23290075Sobrien 23318334Speter/* Language-dependent contents of an identifier. */ 23418334Speter 23518334Speterstruct lang_identifier 23618334Speter{ 23790075Sobrien struct c_common_identifier ignore; 23852284Sobrien tree namespace_bindings; 23952284Sobrien tree bindings; 24018334Speter tree class_value; 24118334Speter tree class_template_info; 24218334Speter struct lang_id2 *x; 24318334Speter}; 24418334Speter 24590075Sobrien/* In an IDENTIFIER_NODE, nonzero if this identifier is actually a 24690075Sobrien keyword.
