+/* Make DECL visible (again?) within SCOPE. When SCOPE is NULL, it

+ that is currently active, even if not at the top of the binding
+ chain.
+
+ This function can be used to make e.g. a global function or
+ variable visible in a namespace or local scope (overriding another
+ enclosing definition of the same name), but its most common
+ expected use of this primitive, that gives it its name, is to make
+ declarations visible again after reentering a function scope,
+ because when a function is entered with push_function, that does
+ NOT make any of the declarations nested in it visible for name
+ lookup.
+
+ There is a reason/excuse for that: unlike namespaces and classes,
+ G++ doesn't ever have to reenter function scopes, so its name
+ resolution infrastructure is not prepared to do that. But wait,
+ there is also a good use for this apparent limitation: a function
+ may contain multiple scopes (blocks), and the name may be bound to
+ different symbols in each of these scopes. With this interface, as
+ we reenter a function scope, we may choose which symbols to make
+ visible for the code snippet, or, if there could be template
+ functions in local scopes, for unresolved names in nested template
+ class default arguments, or in nested template function signatures.
+
+ As for making a local declaration visible for the code snippet,
+ there are two possibilities: a) introduce it upfront, while
+ entering the scope for the user expression (see the enter_scope
+ callback, called by g++ when encountering the push_user_expression
+ pragma), which might save some scope switching and reactivate_decl
+ (though this can't be helped if some declarations have to be
+ introduced and discarded, because of multiple definitions of the
+ same name in different scopes within a function: they have to be
+ defined in discriminator order); or b) introduce it when its name
+ is looked up, entering the scope, introducing the declaration,
+ leaving the scope, and then reactivating the declaration in its
+ local scope.
+
+ Here's some more detail on how reactivate_decl works. Say there's
+ a function foo whose body looks like this:
+
+ {
+ {
+// point 1
+ class c {} o __attribute__ ((__used__)); // c , o
+ }
+ struct c {
+ void f() {
+// point 2
+ }
+ } o __attribute__ ((__used__)); // c_0, o_0
+ {
+ class c {} p __attribute__ ((__used__)); // c_1, p
+// point 3
+ o.f();
+ }
+ }
+
+ When we are about to define class c at point 1, we enter the
+ function foo scope, and since no symbols are visible at point 1, we
+ proceed to declare class c. We may then define the class right
+ away, or, if we leave the function scope, and we later wish to
+ define it, or to define object o, we can reenter the scope and just
+ use the previously-obtained gcc_decl to define the class, without
+ having to reactivate the declaration.
+
+ Now, if we are to set up the binding context for point 2, we have
+ to define c_0::f, and in order to do so, we have to declare and
+ define c_0. Before we can declare c_0, we MUST at least declare c.
+
+ As a general rule, before we can declare or define any local name
+ with a discriminator, we have to at least declare any other
+ occurrences of the same name in the same enclosing entity with
+ lower or absent discriminator.
+
+ So, we declare c, then we leave the function scope and reenter it
+ so as to declare c_0 (also with name "c", which is why we have to
+ leave and reenter the function scope, otherwise we would get an
+ error because of the duplicate definition; g++ will assign a
+ discriminator because it still remembers there was an earlier
+ declaration of c_0 within the function, it's just no longer in
+ scope), then we can define c_0, including its member function f.
+
+ Likewise, if we wish to define o_0, we have to define o first. If
+ we wish to declare (and maybe then define) c_1, we have to at least
+ declare (c and then) c_0 first.
+
+ Then, as we set up the binding context to compile a code snippet at
+ point 3, we may choose to activate c_1, o_0 and p upfront,
+ declaring and discarding c, c_0 and o, and then reentering the
+ funciton scope to declare c_1, o_0 and p; or we can wait for oracle
+ lookups of c, o or p. If c is looked up, and the debugger resolves
+ c in the scope to c_1, it is expected to enter the function scope
+ from the top level, declare c, leave it, reenter it, declare c_0,
+ leave it, reenter it, declare c_1, leave it, and then reactivate
+ c_1 in the function scope. If c_1 is needed as a complete type,
+ the definition may be given right after the declaration, or the
+ scope will have to be reentered in order to define the class.
+
+. If the code snippet is at point 2, we don't need to (re)activate
+ any declaration: nothing from any local scope is visible. Just
+ entering the scope of the class containing member function f
+ reactivates the names of its members, including the class name
+ itself. */
+
+GCC_METHOD2 (int /* bool */, reactivate_decl,
+ gcc_decl, /* Argument DECL. */
+ gcc_decl) /* Argument SCOPE. */
+
+/* Pop the namespace last entered with push_namespace, or class last
+ entered with push_class, or function last entered with

+ matching push_* call. */

+ 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

+ 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.
+
+ Use this function to register typedefs, functions and variables to
+ namespace and local binding levels, and typedefs, member functions
+ (static or not), and static data members to class binding levels.
+ Class members must have their access controls specified with
+ GCC_CP_ACCESS_* flags in SYM_KIND.
+
+ Note that, since access controls are disabled, we have no means to
+ express private, protected and public.
+
+ There are various flags that can be set in SYM_KIND to specify
+ additional semantics. Look for GCC_CP_FLAGs in the definition of
+ enum gcc_cp_symbol_kind in gcc-cp-interface.h.
+
+ In order to define member functions, pass GCC_CP_SYMBOL_FUNCTION in
+ SYM_KIND, and a function_type for static member functions or a
+ method type for non-static member functions, including constructors
+ and destructors. Use build_function_type to create a function
+ type; for a method type, start by creating a function type without
+ any compiler-introduced artificial arguments (the implicit this
+ pointer, and the __in_chrg added to constructors and destructors,
+ and __vtt_parm added to the former), and then use build_method_type
+ to create the method type out of the class type and the function
+ type.
+
+ For operator functions, set GCC_CP_FLAG_SPECIAL_FUNCTION in
+ SYM_KIND, in addition to any other applicable flags, and pass as
+ NAME a string starting with the two-character mangling for operator
+ name: "ps" for unary plus, "mL" for multiply and assign, *=; etc.
+ Use "cv" for type converstion operators (the target type portion
+ may be omitted, as it is taken from the return type in SYM_TYPE).
+ For operator"", use "li" followed by the identifier (the mangled
+ name mandates digits specifying the length of the identifier; if
+ present, they determine the end of the identifier, otherwise, the
+ identifier extents to the end of the string, so that "li3_Kme" and
+ "li_Km" are equivalent).
+
+ Constructors and destructors need special care, because for each
+ constructor and destructor there may be multiple clones defined
+ internally by the compiler. With build_decl, you can introduce the
+ base declaration of a constructor or a destructor, setting
+ GCC_CP_FLAG_SPECIAL_FUNCTION the flag and using names starting with
+ capital "C" or "D", respectively, followed by a digit (see below),
+ a blank, or NUL ('\0'). DO NOT supply an ADDRESS or a
+ SUBSTITUTION_NAME to build_decl, it would be meaningless (and
+ rejected) for the base declaration; use define_cdtor_clone to
+ introduce the address of each clone. For constructor templates,
+ declare the template with build_decl, and then, for each
+ specialization, introduce it with
+ build_function_template_specialization, and then define the
+ addresses of each of its clones with define_cdtor_clone.
