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
node.
<E_Incomplete_Type>: Rework to treat Non_Limited_View, Full_View, and
Underlying_Full_View similarly. Return earlier if the full view already
has an associated tree.
(gnat_to_gnu_entity) <E_Record_Type>: Restore comment.
(gnat_to_gnu_entity) <E_Record_Type>: Do not use a dummy type.

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.

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.

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.

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.
(GET_DUMMY_NODE, SET_DUMMY_NODE, PRESENT_DUMMY_NODE): New macros.

(tree_code_for_record_type): New function extracted from make_dummy_type
(init_gigi_decls): Set DECL_IS_MALLOC on gnat_malloc.

(static_dtors): Likewise.
(end_subprog_body): Adjust for above change.
(build_global_cdtor): Moved from trans.c.
(gnat_write_global_declarations): Emit global constructor and
destructor, and call cgraph_optimize before emitting debug info for
global declarations.
(global_decls): New global variable.
(gnat_pushdecl): Store the global declarations in global_decls, for
later use.
(gnat_write_global_declarations): Emit debug information for global
declarations.
(create_var_decl_1): Former create_var_decl, with an extra argument to
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.
* misc.c (gnat_dwarf_name): New function.
(LANG_HOOKS_DWARF_NAME): Define to gnat_dwarf_name.
(gnat_post_options): Add comment about structural alias analysis.
(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.

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.

(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.
