+ * gcc-interface/gigi.h (gnat_mark_addressable): Rename parameter.
+ * gcc-interface/decl.c (maybe_variable): Do not set TREE_STATIC on _REF
+ node. Use the type of the operand to set TREE_READONLY.
+ * gcc-interface/trans.c (Identifier_to_gnu): Do not set TREE_STATIC on
+ _REF node. Do not overwrite TREE_READONLY.
+ (call_to_gnu): Rename local variable and fix various nits. In the
+ copy-in/copy-out case, build the SAVE_EXPR manually.
+ (convert_with_check): Call protect_multiple_eval in lieu of save_expr
+ and fold the computations.
+ (protect_multiple_eval): Always save entire fat pointers.
+ (maybe_stabilize_reference): Minor tweaks.
+ (gnat_stabilize_reference_1): Likewise. Do not deal with tcc_constant,
+ tcc_type and tcc_statement.
+ * gcc-interface/utils.c (convert_to_fat_pointer): Call
+ protect_multiple_eval in lieu of save_expr.
+ (convert): Minor tweaks.
+ (maybe_unconstrained_array): Do not set TREE_STATIC on _REF node.
+ (builtin_type_for_size): Call gnat_type_for_size directly.
+ * gcc-interface/utils2.c (contains_save_expr_p): Delete.
+ (contains_null_expr): Likewise
+ (gnat_build_constructor): Do not call it.
+ (compare_arrays): Deal with all side-effects, use protect_multiple_eval
+ instead of gnat_stabilize_reference to protect the operands.
+ (nonbinary_modular_operation): Call protect_multiple_eval in lieu of
+ save_expr.
+ (maybe_wrap_malloc): Likewise.
+ (build_allocator): Likewise.
+ (build_unary_op) <INDIRECT_REF>: Do not set TREE_STATIC on _REF node.
+ (gnat_mark_addressable): Rename parameter.

+ * gcc-interface/ada-tree.h (TYPE_RETURNS_UNCONSTRAINED_P): Rename into.
+ (TYPE_RETURN_UNCONSTRAINED_P): ...this.
+ (TYPE_RETURNS_BY_REF_P): Rename into.
+ (TYPE_RETURN_BY_DIRECT_REF_P): ...this.
+ (TYPE_RETURNS_BY_TARGET_PTR_P): Delete.
+ * gcc-interface/gigi.h (create_subprog_type): Adjust parameter names.
+ (build_return_expr): Likewise.
+ * gcc-interface/decl.c (gnat_to_gnu_entity) <E_Subprogram_Type>:
+ Rename local variables. If the return Mechanism is By_Reference, pass
+ return_by_invisible_ref_p to create_subprog_type instead of toggling
+ TREE_ADDRESSABLE. Test return_by_invisible_ref_p in order to annotate
+ the mechanism. Use regular return for contrained types with non-static
+ size and return by invisible reference for unconstrained return types
+ with default discriminants. Update comment.
+ * gcc-interface/trans.c (Subprogram_Body_to_gnu): If the function
+ returns by invisible reference, turn the RESULT_DECL into a pointer.
+ Do not handle DECL_BY_REF_P in the CICO case here.
+ (call_to_gnu): Remove code handling return by target pointer. For a
+ function call, if the return type has non-constant size, generate the
+ assignment with an INIT_EXPR.
+ (gnat_to_gnu) <N_Return_Statement>: Remove dead code in the CICO case.
+ If the function returns by invisible reference, build the copy return
+ operation manually.
+ (add_decl_expr): Initialize the variable with an INIT_EXPR.
+ * gcc-interface/utils.c (create_subprog_type): Adjust parameter names.
+ Adjust for renaming of macros. Copy the node only when necessary.
+ (create_subprog_decl): Do not toggle TREE_ADDRESSABLE on the return
+ type, only change DECL_BY_REFERENCE on the RETURN_DECL.
+ (convert_from_reference): Delete.
+ (is_byref_result): Likewise.
+ (gnat_genericize_r): Likewise.
+ (gnat_genericize): Likewise.
+ (end_subprog_body): Do not call gnat_genericize.
+ * gcc-interface/utils2.c (build_binary_op) <INIT_EXPR>: New case.
+ (build_return_expr): Adjust parameter names, logic and comment.

+
+ * exp_pakd.adb (Create_Packed_Array_Type): Always use a modular type
+ if the size is small enough. Propagate the alignment if there is an
+ alignment clause on the original array type.
+ * gcc-interface/decl.c (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>
+ Deal with under-aligned packed array types. Copy the size onto the
+ justified modular type and don't lay it out again. Likewise for the
+ padding type built for other under-aligned subtypes.
+ * gcc-interface/utils.c (finish_record_type): Do not set a default mode
+ on the type.

+
+ * gcc-interface/trans.c (call_to_gnu): In the return-by-target-ptr case
+ do not set the result type if there is a specified target and do not

+ (protect_multiple_eval): Make direct SAVE_EXPR for CALL_EXPR.
+ (maybe_stabilize_reference) <COMPOUND_EXPR>: Merge with CALL_EXPR.
