tree before setting TREE_ADDRESSABLE for by-reference return mechanism
processing.
(gnat_to_gnu_entity): Remove From_With_Type from computation for
imported_p.
<E_Access_Type>: Use the Non_Limited_View as the full view of the
designated type if the pointer comes from a limited_with clause. Make
incomplete designated type if it is in the main unit and has a freeze

Use create_true_var_decl with const_flag set for
DECL_CONST_CORRESPONDING_VARs, ensuring a VAR_DECL is created with
TREE_READONLY set.
(gnat_to_gnu_entity, case E_Enumeration_Type): Set TYPE_NAME
for Character and Wide_Character types. This info is read by the
dwarf-2 writer, and is needed to be able to use the command "ptype
character" in the debugger.
(gnat_to_gnu_entity): When generating a type representing
a Character or Wide_Character type, set the flag TYPE_STRING_FLAG,
so that debug writers can distinguish it from ordinary integers.
(elaborate_expression_1): Test the DECL_READONLY_ONCE_ELAB flag in
addition to TREE_READONLY to assert the constantness of variables for
elaboration purposes.
(gnat_to_gnu_entity, subprogram cases): Change loops on formal
parameters to call new Einfo function First_Formal_With_Extras.

TYPE_NONALIASED_COMPONENT to 0 if the element type is an aggregate.
<E_Array_Subtype>: Likewise.
(gnat_to_gnu_entity) <E_Incomplete_Subtype>: Add support for regular
incomplete subtypes and incomplete subtypes of incomplete types visible
through a limited with clause.
(gnat_to_gnu_entity) <E_Array_Subtype>: Take into account the bounds of
the base index type for the maximum size of the array only if they are
constant.
(gnat_to_gnu_entity, renaming object case): Do not wrap up the
expression into a SAVE_EXPR if stabilization failed.
* utils.c (create_subprog_decl): Turn TREE_ADDRESSABLE on the type of
a result decl into DECL_BY_REFERENCE on this decl, now what is expected
by lower level compilation passes.
(gnat_genericize): New function, lowering a function body to GENERIC.
Turn the type of RESULT_DECL into a real reference type if the decl
has been marked DECL_BY_REFERENCE, and adjust references to the latter
accordingly.

gnat_genericize.
(convert_from_reference, is_byref_result): New functions. Helpers for
gnat_genericize_r.
(create_type_decl): Call gnat_pushdecl before calling
rest_of_decl_compilation, to make sure that field TYPE_NAME of
type_decl is properly set before calling the debug information writers.
(write_record_type_debug_info): The heuristics which compute the
alignment of a field in a variant record might not be accurate. Add a
safety test to make sure no alignment is set to a smaller value than
the alignment of the field type.
(make_dummy_type): Use the Non_Limited_View as the underlying type if
the type comes from a limited_with clause. Do not loop on the full view.
(GET_GNU_TREE, SET_GNU_TREE, PRESENT_GNU_TREE): New macros.
(dummy_node_table): New global variable, moved from decl.c.

state whether the creation of a CONST_DECL is allowed.
(create_var_decl): Behavior unchanged. Now a wrapper around
create_var_decl_1 allowing CONST_DECL creation.
(create_true_var_decl): New function, similar to create_var_decl but
forcing the creation of a VAR_DECL node (CONST_DECL not allowed).
(create_field_decl): Do not always mark the field as addressable
if its type is an aggregate.
(global_renaming_pointers): New static variable.
(add_global_renaming_pointer): New function.
(get_global_renaming_pointers): Likewise.

(gnat_parse_file): Do not call cgraph_optimize here.
(LANG_HOOKS_WRITE_GLOBALS): Define to gnat_write_global_declarations.
* trans.c (process_freeze_entity): Don't abort if we already have a
non dummy GCC tree for a Concurrent_Record_Type, as it might
legitimately have been elaborated while processing the associated
Concurrent_Type prior to this explicit freeze node.
(Identifier_to_gnu): Do not make a variable referenced in a SJLJ
exception handler volatile if it is of variable size.
(process_type): Remove bypass for types coming from a limited_with
clause.
(call_to_gnu): When processing the copy-out of a N_Type_Conversion GNAT
actual, convert the corresponding gnu_actual to the real destination
type when necessary.
(add_decl_expr): Set the DECL_READONLY_ONCE_ELAB flag on variables
originally TREE_READONLY but whose elaboration cannot be performed
statically.
Part of fix for F504-021.
(tree_transform, subprogram cases): Change loops on formal parameters to
call new Einfo function First_Formal_With_Extras.
(gnat_to_gnu) <N_Op_Shift_Right_Arithmetic>: Ignore constant overflow
stemming from type conversion for the lhs.
(Attribute_to_gnu) <Attr_Alignment>: Also divide the alignment by the
number of bits per unit for components of records.
(gnat_to_gnu) <N_Code_Statement>: Mark operands addressable if needed.
(Handled_Sequence_Of_Statements_to_gnu): Register the cleanup associated
with At_End_Proc after the SJLJ EH cleanup.
(Compilation_Unit_to_gnu): Call elaborate_all_entities only on the main
compilation unit.
(elaborate_all_entities): Do not retest type_annotate_only.
(tree_transform) <N_Abstract_Subprogram_Declaration>: Process the
result type of an abstract subprogram, which may be an itype associated
with an anonymous access result (related to AI-318-02).
(build_global_cdtor): Move to utils.c.
(Case_Statement_to_gnu): Avoid adding the choice of a when statement if
this choice is not a null tree nor an integer constant.
(gigi): Run unshare_save_expr via walk_tree_without_duplicates
on the body of elaboration routines instead of mark_unvisited.
(add_stmt): Do not mark the tree.
(add_decl_expr): Tweak comment.
(mark_unvisited): Delete.
(unshare_save_expr): New static function.
(call_to_gnu): Issue an error when making a temporary around a
procedure call because of non-addressable actual parameter if the
type of the formal is by_reference.

current compilation version is Ada 05 and the supplied node has an
access definition.
(Instantiate object): Alphabetize local variables. Handle the creation
of new renaming declarations with respect to the kind of definition
used - either an access definition or a subtype mark. Guard against
unnecessary error message in the context of anonymous access types after
they have been resolved. Add check for required null exclusion in a
formal object declaration.
(Switch_View): A private subtype of a non-private type needs to be
switched (the base type can have been switched without its private
dependents because of the last branch of Check_Private_View.
(Check_Private_View): Do not recompute Base_Type (T), instead use cached
value from BT.
(Instantiate_Type): Emit an error message whenever a class-wide type of
a tagged incomplete type is used as a generic actual.
(Find_Actual_Type): Extend routine to handle a component type in a child
unit that is imported from a formal package in a parent.
(Validate_Derived_Type_Instance): Check that analyzed formal and actual
agree on constrainedness, rather than checking against ultimate ancestor
(Instantiate_Subprogram_Body): Create a cross-reference link to the
generic body, for navigation purposes.

P_Return_Statement): Parse the new syntax for extended_return_statement.
* par-endh.adb (Check_End, Output_End_Deleted, Output_End_Expected,
Output_End_Missing): Add error-recovery code for the new
extended_return_statement syntax; that is, the new E_Return entry on
the scope stack.
* s-auxdec-vms_64.ads, s-auxdec.ads (AST_Handler): Change type from
limited to nonlimited, because otherwise we violate the new Ada 2005
rules about returning limited types in function Create_AST_Handler in
s-asthan.adb.
* sem.adb (Analyze): Add cases for new node kinds
N_Extended_Return_Statement and N_Return_Object_Declaration.
* sem_aggr.adb (Aggregate_Constraint_Checks): Verify that component
type is in the same category as type of context before applying check,
to prevent anomalies in instantiations.
(Resolve_Aggregate): Remove test for limited components in aggregates.
It's unnecessary in Ada 95, because if it has limited components, then
it must be limited. It's wrong in Ada 2005, because limited aggregates
are now allowed.
(Resolve_Record_Aggregate): Move check for limited types later, because
OK_For_Limited_Init requires its argument to have been resolved.
(Get_Value): When copying the component default expression for a
defaulted association in an aggregate, use the sloc of the aggregate
and not that of the original expression, to prevent spurious
elaboration errors, when the expression includes function calls.
(Check_Non_Limited_Type): Correct code for AI-287, extension aggregates
were missing. We also didn't handle qualified expressions. Now also
allow function calls. Use new common routine OK_For_Limited_Init.
(Resolve_Extension_Aggregate): Minor fix to bad error message (started
with space can upper case letter).

type with discriminants.
(Process_Range_Expr_In_Decl): Do validity checks on range
(Build_Discriminant_Constraints): Use updated form of

(Process_Subtype): If the subtype is a private subtype whose full view
is a concurrent subtype, introduce an itype reference to prevent scope
anomalies in gigi.
(Build_Derived_Record_Type, Collect_Interface_Primitives,
Record_Type_Declaration): The functionality of the subprograms
Collect_Abstract_Interfaces and Collect_All_Abstract_Interfaces
is now performed by a single routine.
(Build_Derived_Record_Type): If the type definition includes an explicit
indication of limitedness, then the type must be marked as limited here
to ensure that any access discriminants will not be treated as having
a local anonymous access type.
(Check_Abstract_Overriding): Issue a detailed error message when an
abstract subprogram was not overridden due to incorrect mode of its
first parameter.
(Analyze_Private_Extension_Declaration): Add support for the analysis of
synchronized private extension declarations. Verify that the ancestor is
a limited or synchronized interface or in the generic case, the ancestor
is a tagged limited type or synchronized interface and all progenitors
are either limited or synchronized interfaces.
Derived_Type_Declaration): Check for presence of private extension when
dealing with synchronized formal derived types.
Process_Full_View): Enchance the check done on the usage of "limited" by
testing whether the private view is synchronized.
Verify that a synchronized private view is completed by a protected or
task type.
(OK_For_Limited_Init_In_05): New function.
(Analyze_Object_Declaration): Move check for limited types later,
because OK_For_Limited_Init requires its argument to have been resolved.
Add -gnatd.l --Use Ada 95 semantics for limited function returns,
in order to alleviate the upward compatibility introduced by AI-318.
(Constrain_Corresponding_Record): If the constraint is for a component
subtype, mark the itype as frozen, to avoid out-of-scope references to
discriminants in the back-end.
(Collect_Implemented_Interfaces): Protect the recursive algorithm of
this subprogram against wrong sources.
(Get_Discr_Value, Is_Discriminant): Handle properly references to a
discriminant of limited type completed with a protected type, when the
discriminant is used to constrain a private component of the type, and
expansion is disabled.
(Find_Type_Of_Object): Do not treat a return subtype that is an
anonymous subtype as a local_anonymous_type, because its accessibility
level is the return type of the enclosing function.
(Check_Initialization): In -gnatg mode, turn the error "cannot
initialize entities of limited type" into a warning.
(OK_For_Limited_Init): Return true for generated nodes, since it
sometimes violates the legality rules.
(Make_Incomplete_Declaration): If the type for which an incomplete
declaration is created happens to be the currently visible entity,
preserve the homonym chain when removing it from visibility.
(Check_Conventions): Add support for Ada 2005 (AI-430): Conventions of
inherited subprograms.
(Access_Definition): If this is an access to function that is the return
type of an access_to_function definition, context is a type declaration
and the scope of the anonymous type is the current one.
(Analyze_Subtype_Declaration): Add the defining identifier of a regular
incomplete subtype to the set of private dependents of the original
incomplete type.
(Constrain_Discriminated_Type): Emit an error message whenever an
incomplete subtype is being constrained.
(Process_Incomplete_Dependents): Transform an incomplete subtype into a
corresponding subtype of the full view of the original incomplete type.
(Check_Incomplete): Properly detect invalid usage of incomplete types
and subtypes.

* exp_ch3.ads, exp_ch3.adb (Expand_N_Object_Declaration): Do not
register in the final list objects containing class-wide interfaces;
otherwise we incorrectly register the tag of the interface in the final
list.
(Make_Controlling_Function_Wrappers): Add missing barrier to do not
generate the wrapper if the parent primitive is abstract. This is
required to report the correct error message.
(Expand_N_Subtype_Indication): Do validity checks on range
(Clean_Task_Names): If an initialization procedure includes a call to
initialize a task (sub)component, indicate that the procedure will use
the secondary stack.
(Build_Init_Procedure, Init_Secondary_Tags): Enable full ABI
compatibility for interfacing with CPP by default.
(Expand_N_Object_Declaration): Only build an Adjust call when the
object's type is a nonlimited controlled type.
* exp_ch3.adb: Add with and use of Exp_Ch6.
(Expand_N_Object_Declaration): Check for object initialization that is a
call to build-in-place function and apply Make_Build_In_Place_Call_In_
Object_Declaration to the call.
(Freeze_Type): When the designated type of an RACW was not frozen at the
point where the RACW was declared, validate the primitive operations
with respect to E.2.2(14) when it finally is frozen.
(Build_Initialization_Call,Expand_Record_Controller): Rename
Is_Return_By_Reference_Type to be Is_Inherently_Limited_Type, because
return-by-reference has no meaning in Ada 2005.
(Init_Secondary_Tags): Add missing call to Set_Offset_To_Top
to register tag of the immediate ancestor interfaces in the
run-time structure.
(Init_Secondary_Tags): Moved to the specification to allow the
initialization of extension aggregates with abstract interfaces.
(Build_Master_Renaming): Make public, for use by function declarations
whose return type is an anonymous access type.
(Freeze_Record_Type): Replace call to Insert_List_Before by call to
Insert_List_Before_And_Analyze after the generation of the specs
associated with null procedures.
(Expand_Tagged_Root): Update documentation in its specification.
(Init_Secondary_Tags): Update documentation.
(Build_Init_Procedure): If we are compiling under CPP full ABI compa-
tibility mode and the immediate ancestor is a CPP_Pragma tagged type
then generate code to inherit the contents of the dispatch table
directly from the ancestor.
(Expand_Record_Controller): Insert controller component after tags of
implemented interfaces.
(Freeze_Record_Type): Call new procedure Make_Null_Procedure_Specs to
create null procedure overridings when null procedures are inherited
from interfaces.
(Make_Null_Procedure_Specs): New procedure to generate null procedure
declarations for overriding null primitives inherited from interfaces.
(Is_Null_Interface_Procedure): New function in
Make_Null_Procedure_Specs.
(Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): If the
immediate ancestor of a tagged type is an abstract interface type we
must generate the specification of the predefined primitives associated
with controlled types (because the dispatch table of the ancestor is
null and hence these entries cannot be inherited). This is required to
elaborate well the dispatch table.

(Expand_N_Attribute_Reference, case Attribute_Constrained): For Ada_05,
test Is_Constrained_Aliased_View rather than Is_Aliased_View, because
an aliased prefix must be known to be constrained in order to use True
for the attribute value, and now it's possible for some aliased views
to be unconstrained.
