A decl is a declaration, basically a kind of symbol. NAME is the name of the new symbol. SYM_KIND is the kind of symbol being requested. SYM_TYPE is the new symbol's C type; except for labels, where this is not meaningful and should be zero. If SUBSTITUTION_NAME is not NULL, then a reference to this decl in the source will later be substituted with a dereference of a variable of the given name. Otherwise, for symbols having an address (e.g., functions), ADDRESS is the address. FILENAME and LINE_NUMBER refer to the symbol's source location. If this is not known, FILENAME can be NULL and LINE_NUMBER can be 0. This function returns the new decl. */ GCC_METHOD7 (gcc_decl, build_decl, const char *, /* Argument NAME. */ enum gcc_c_symbol_kind, /* Argument SYM_KIND. */ gcc_type, /* Argument SYM_TYPE. */ const char *, /* Argument SUBSTITUTION_NAME. */ gcc_address, /* Argument ADDRESS. */ const char *, /* Argument FILENAME. */ unsigned int) /* Argument LINE_NUMBER. */ /* Insert a GCC decl into the symbol table.
