2010-04-09 Eric Botcazou * 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) : Do not set TREE_STATIC on _REF node. (gnat_mark_addressable): Rename parameter. 2010-04-08 Eric Botcazou * 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) : 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) : 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.

(build_return_expr): Adjust parameter names, logic and comment. 2010-04-07 Eric Botcazou * 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) 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. 2010-04-07 Eric Botcazou * gcc-interface/decl.c (gnat_to_gnu_entity) : Set default alignment on the RETURN type built for the Copy-In Copy-Out mechanism. 2010-04-07 Eric Botcazou * 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 convert the result in any cases. (protect_multiple_eval): Make direct SAVE_EXPR for CALL_EXPR. (maybe_stabilize_reference) : Merge with CALL_EXPR. 2010-03-10 Eric Botcazou * gcc-interface/Makefile.in (SPARC/Solaris): Use sparcv8plus. 2010-02-27 Eric Botcazou PR ada/42253 * gcc-interface/utils2.c (build_binary_op) : Assert that fat pointer base types are variant of each other.
