* tree.h (TREE_ADDRESSABLE): Document its effect for function types. * calls.c (expand_call): Pass the function type to aggregate_value_p. * function.c (aggregate_value_p): Do not honor DECL_BY_REFERENCE on the target function of a CALL_EXPR. Honor TREE_ADDRESSABLE on the function type instead. Reorder and simplify checks. * gimplify.c (gimplify_modify_expr_rhs) <WITH_SIZE_EXPR>: New case. ada/ * 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. From-SVN: r158139 |

README
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully.
