- (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.
