(Gnat1drv): Set Back_End_Mode to Declarations_Only in GNATprove mode, and later on special case the GNATprove mode to continue analysis anyway. * lib-writ.adb (Write_ALI): Always generate ALI files in GNATprove mode. * opt.adb, opt.ads (Full_Expander_Active): Make it equivalent to Expander_Active. (SPARK_Mode): Renamed as GNATprove_Mode. * sem_aggr.adb (Aggregate_Constraint_Checks): Add checks in the tree in GNATprove_Mode. * sem_ch12.adb (Analyze_Package_Instantiation): Always instantiate body in GNATprove mode. (Need_Subprogram_Instance_Body): Always instantiate body in GNATprove mode. * sem_ch3.adb (Constrain_Index, Process_Range_Expr_In_Decl): Make sure side effects are removed in GNATprove mode. 2014-01-20 Eric Botcazou * gcc-interface/decl.c (gnat_to_gnu_entity) : Robustify tests for aliased objects with an unconstrained nominal subtype. * gcc-interface/trans.c (Call_to_gnu): Likewise. (gnat_to_gnu) : Robustify test for private type. : Remove useless code. (Exception_Handler_to_gnu_zcx): Minor tweaks. 2014-01-20 Eric Botcazou * gcc-interface/decl.c (gnat_to_gnu_entity) : Tidy up. For a subtype with discriminants and variant part, if a variant is statically selected and the fields all have a constant position, put them in order of increasing position. Likewise if no variant part but representation clause is present. * gcc-interface/utils.c (make_packable_type): Robustify. (maybe_pad_type): Use local variable and tidy up condition. If no alignment is specified, use the original one. (create_type_stub_decl): Minor tweak. (convert) : Fix typo. : Deal with padding types around the same type. Do not punt on missing fields. (unchecked_convert): Call finish_record_type to lay out the special record types made for conversions from/to problematic integer types. Bump the alignment of CONSTRUCTORs before converting them to a more aligned type. 2014-01-20 Eric Botcazou * gcc-interface/decl.c (gnat_to_gnu_entity) : Remove obsolete code for type_annotate_only mode, simplify code and slightly improve wording of comments. 2014-01-12 Eric Botcazou PR ada/59772 * gcc-interface/cuintp.c (build_cst_from_int): Use 32-bit integer type as intermediate type. (UI_To_gnu): Likewise. 2014-01-03 Eric Botcazou * gnatvsn.ads (Current_Year): Bump to 2014. 2014-01-02 Tobias Burnus * gnat_ugn.texi: Bump @copying's copyright year.
