951 have a subtype indication and the type is an unconstrained tagged
952 type with defaulted discriminants, create an explicit constraint
953 for it during analysis to prevent out-of-order freezing actions
954 on generated classwide types.
956 2016-05-02 Javier Miranda <miranda@adacore.com>
958 * exp_ch5.adb (Expand_N_Assignment_Statement):

965 * sem_attr.adb (Analyze_Attribute, case 'Old): Do not use
966 base type for attribute when type is discrete: transformation

1342 procedure to compute the dimension vector of a scalar expression
1343 and compare it with the dimensions if its expected subtype. Used

1404 assignments also in entries and task bodies, not only in
1405 procedures and declaration blocks.
1406 * sem_ch5.adb (Analyze_Block_Statement): check useless
1407 assignements in declaration blocks as part of processing their

2048 (possibly later) freeze point of the type. This also allows uses
2049 of a type with predicates in instantiations elsewhere.
2050 (Resolve_Aspect_Expression): New procedure to detect visiblity
2051 errors in aspect expressions, at the end of the declarative part
2052 that includes the type declaration.

2089 hiding unless we're actually hiding something. The previous
2090 code would (for example) warn about a "<" on a record type

2092 in Standard. We need to check that the homonym S is in fact a

2443 the tree. Do not replace the type references for ASIS when

2569 variables that do not change as constants and initialize them
2572 2016-04-19 Ed Schonberg <schonberg@adacore.com>
2574 * sem_res.adb (Resolve_Entry_Call): If the entry has
2575 preconditions it is rewritten by means of a wrapper that
2576 incorporates the original call. Before rewriting generate a
2577 reference to the entry being called to prevent spurious warnings
2578 and provide correct cross-reference information.
2580 2016-04-19 Hristian Kirtchev <kirtchev@adacore.com>
2582 * sem_disp.adb (Check_Dispatching_Context): Code cleanup. Add
2583 local constant Scop. Ignore any internally generated loops when
2584 performing the check concerning an abstract subprogram call
2585 without a controlling argument.

2588 2016-04-19 Bob Duff <duff@adacore.com>
2590 * sem_elab.adb (Check_A_Call): There are cases where we have No
2591 (Ent) after the Alias loop, even when there was no previous error,
2592 so we can't assert that there was an error.
2594 2016-04-19 Ed Schonberg <schonberg@adacore.com>
2596 * sem_attr.adb (Analyze_Access_Attribute, OK_Self_Reference):
2597 Reject use of type name as a prefix to 'access within an aggregate
2598 in a context that is not the declarative region of a type.
2600 2016-04-19 Vincent Celier <celier@adacore.com>
2602 * gnatcmd.adb: Make "gnat ls -P" invoke gprls Make "gnat bind

2604 -l" Fail if the invocation is "gnat find -P" or "gnat xref -P"
2605 Remove anything related to project files
2606 * g-mbdira.adb: minor whitespace cleanup
2607 * g-spipat.adb: minor removal of extra spaces after closing paren
2609 2016-04-19 Ed Schonberg <schonberg@adacore.com>
2611 * exp_ch6.adb (Expand_Actuals): If post-statements are present
2612 and the enclosing context is a function call or indexing, build
2613 an Expression_With_Actions for the call.
2615 2016-04-19 Hristian Kirtchev <kirtchev@adacore.com>
2617 * lib-writ.adb (Write_With_Lines): Code cleanup. Do not generate
2618 a with line for an ignored Ghost unit.
2619 * sem_ch7.adb (Analyze_Package_Declaration): Add local constant
2620 Par. A child package is Ghost when its parent is Ghost.
2621 * sem_prag.adb (Analyze_Pragma): Pragma Ghost can now apply to
2622 a subprogram declaration that acts as a compilation unit.
2624 2016-04-18 Michael Matz <matz@suse.de>
2626 * gcc-interface/decl.c (gnat_to_gnu_entity): Use SET_TYPE_ALIGN.

2636 (finish_record_type): Ditto and use SET_DECL_ALIGN.
2637 (rest_of_record_type_compilation): Use SET_TYPE_ALIGN.
2638 (create_field_decl): Use SET_DECL_ALIGN.
2640 2016-04-18 Arnaud Charlet <charlet@adacore.com>

2681 * sem_eval.adb, sem_eval.ads (Check_Non_Static_Context): Add
2682 comment to document usage of subprogram in GNATprove.
2684 2016-04-18 Ed Schonberg <schonberg@adacore.com>
2686 * sem_prag.adb (Analyze_Pragma, case Test_Case): Improve error
2687 message for wrong placement of aspect Test_Case.

2691 * einfo.ads: Update the documentation of attribute Renamed_Object.
2692 * exp_spark.adb (Expand_Potential_Renaming): Reimplemented.
2694 2016-04-18 Gary Dismukes <dismukes@adacore.com>
2696 * exp_ch4.adb (Optimize_Length_Comparison): Return immediately
2697 in the case of AAMP (same as for use of the -gnatd.P switch) to
2698 suppress this optimization, which avoids creating a dependence
2699 on the 64-bit arithmetic package.
2701 2016-04-18 Arnaud Charlet <charlet@adacore.com>
2703 * exp_ch4.adb: Update comment.
2705 2016-04-18 Eric Botcazou <ebotcazou@adacore.com>
2707 * exp_ch6.adb (Expand_Call): Make sure instantiations are
2708 registered only once as pending here.
2710 2016-04-18 Arnaud Charlet <charlet@adacore.com>
2712 * exp_ch4.adb, gnat1drv.adb, opt.ads, sem_res.adb
2713 (Minimize_Expression_With_Actions): New flag.

2719 Expand_Short_Circuit_Operator): Restore old code to avoid
2720 Expression_With_Actions when Minimize_Expression_With_Actions
2723 2016-04-18 Vincent Celier <celier@adacore.com>
2725 * s-os_lib.adb (Non_Blocking_Spawn, version with Stdout_File and
2726 Stderr_File): Close local file descriptors when no longer needed.
2728 2016-04-18 Ed Schonberg <schonberg@adacore.com>
2730 * sem_ch5.adb (Analyze_Iterator_Specification): Remove SPARK
2731 mode check that the type of the cursor in an iteration over
2732 a formal container is not volatile. The proper check on the
2733 element type is done elsewhere.
2735 2016-04-18 Ed Schonberg <schonberg@adacore.com>
2737 * sem_ch6.adb (Process_Formals): Do not set a delay freeze on
2738 a subprogram that returns a class-wide type, if the subprogram
2739 is a compilation unit, because otherwise gigi will treat the
2740 subprogram as external, leading to link errors.
2742 2016-04-18 Arnaud Charlet <charlet@adacore.com>
2744 * sem_res.adb (Resolve_Short_Circuit): Do not use
2745 expression-with-actions when generating C.

2754 * s-fileio.adb: Minor reformatting.
2755 * sem_prag.adb (Analyze_Input_Item): Add local
2756 variable Input_OK. Do not consider mappings of generic formal
2757 parameters to actuals.
2759 2016-04-18 Ed Schonberg <schonberg@adacore.com>
2761 * sem_ch5.adb (Get_Cursor_Type): If iterator type is a derived
2762 type, the cursor is declared in the scope of the parent type.
2763 (Analyze_Parameter_Specification): A qualified expression with an
2764 iterator type indicates an iteration over a container (explicit
2767 2016-04-18 Arnaud Charlet <charlet@adacore.com>
2769 * osint-c.ads, osint-c.adb (Delete_C_File, Delete_H_File): New.
2770 * gnat1drv.adb (Gnat1drv): Delete old C files before regenerating them.
2771 * debug.adb: Reserve -gnatd.4 to force generation of C files.
2773 2016-04-18 Yannick Moy <moy@adacore.com>
2775 * sem_eval.adb (Eval_Arithmetic_Op): Do not issue error on static
2776 division by zero, instead possibly issue a warning.
2777 * sem_res.adb (Resolve_Arithmetic_Op): Do not issue error on
2778 static division by zero, instead add check flag on original
2780 * sem_util.adb, sem_util.ads (Compile_Time_Constraint_Error):
2781 Only issue error when both SPARK_Mode is On and Warn is False.
2783 2016-04-18 Yannick Moy <moy@adacore.com>
2785 * checks.adb (Apply_Scalar_Range_Check): Force
2786 warning instead of error when SPARK_Mode is On, on index out of
2787 bounds, and set check flag for GNATprove.
2789 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
2791 * sem_prag.adb (Check_In_Out_States.Check_Constituent_Usage):
2792 Update the comment on usage. Reimplemented.
2793 (Check_Input_States.Check_Constituent_Usage): Update the comment
2794 on usage. A Proof_In constituent can now refine an Input state
2795 as long as there is at least one Input constituent present.
2797 2016-04-18 Ed Schonberg <schonberg@adacore.com>
2799 * sem_ch6.adb (Check_Inline_Pragma): Use the Sloc of the
2800 body id as the sloc of the entity in the generated subprogram
2801 declaration, to avoid spurious conformance errors when style
2804 2016-04-18 Ed Schonberg <schonberg@adacore.com>
2806 * sem_ch4.adb (Analyze_Selected_Component, Has_Dereference):
2807 Refine check on illegal calls to entities within a task body,
2808 when the entity is declared in an object of the same type. In
2809 a generic context there might be no explicit dereference but if
2810 the prefix includes an access type the construct is legal.
2812 2016-04-18 Arnaud Charlet <charlet@adacore.com>
2814 * rtsfind.ads, rtsfind.adb (RE_Id, RE_Unit_Table): add
2815 RE_Default_Priority.
2817 2016-04-18 Bob Duff <duff@adacore.com>
2819 * sem_prag.adb (Check_Arg_Is_Local_Name): Don't do the check
2820 if the pragma came from an aspect specification.
2822 2016-04-18 Gary Dismukes <dismukes@adacore.com>
2824 * gnat1drv.adb, contracts.adb: Minor reformatting and wording fixes.
2826 2016-04-18 Ed Schonberg <schonberg@adacore.com>
2828 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): To suppress
2829 superfluous conformance check on an inlined body with a previous
2830 spec, use the fact that the generated declaration does not come
2831 from source. We must treat the entity as coming from source to
2832 enable some back-end inlining when pragma appears after the body.
2834 2016-04-18 Gary Dismukes <dismukes@adacore.com>
2836 * lib-xref-spark_specific.adb, par-ch2.adb, errout.ads,
2837 exp_intr.adb: Minor reformatting and typo corrections.
2839 2016-04-18 Ed Schonberg <schonberg@adacore.com>
2841 * sem_ch6.adb: Code cleanup.
2843 2016-04-18 Thomas Quinot <quinot@adacore.com>
2845 * sem_ch13.adb: Minor reformatting and error message tweaking
2846 (remove extraneous spaces).
2848 2016-04-18 Johannes Kanig <kanig@adacore.com>
2850 * gnat1drv.adb (Gnat1drv): Force loading of System unit for SPARK.
2852 2016-04-18 Bob Duff <duff@adacore.com>
2854 * s-fileio.adb (Fopen_Mode): If Mode = Out_File, and the file
2855 exists, and it's a fifo, we use "w" as the open string instead of
2856 "r+". This is necessary to make a write to the fifo block until
2859 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
2861 * sem_attr.adb (Denote_Same_Function): Account
2862 for a special case where a primitive of a tagged type inherits
2863 a class-wide postcondition from a parent type.
2865 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
2867 * par-ch2.adb (P_Expression_Or_Reserved_Word): New routine.
2868 (P_Pragma): Signal Scan_Pragma_Argument_Association when the use
2869 of reserved words is OK.
2870 (Scan_Pragma_Argument_Association):
2871 Add new formal Reserved_Words_OK and update the comment on
2872 usage. Code cleanup. Parse an expression or a reserved word in
2873 identifier form for pragmas Restriction_Warnings and Restrictions
2874 No_Use_Of_Attribute.
2875 * restrict.adb (Check_Restriction_No_Use_Of_Attribute):
2876 Reimplemented. (Check_Restriction_No_Use_Of_Pragma): Code cleanup.
2877 (Set_Restriction_No_Specification_Of_Aspect): Properly set the warning
2879 (Set_Restriction_No_Use_Of_Attribute): Properly set the warning
2880 flag for an attribute. (Set_Restriction_No_Use_Of_Entity):
2881 Update the parameter profile.
2882 (Set_Restriction_No_Use_Of_Pragma): Properly set the warning flag for
2884 * restrict.ads (Check_Restriction_No_Use_Of_Attribute): Update
2885 the comment on usage.
2886 (Set_Restriction_No_Use_Of_Entity): Update the parameter profile.
2887 * sem_attr.adb (Analyze_Attribute): Check restriction
2888 No_Use_Of_Attribute.
2889 * sem_ch13.adb (Analyze_Attribute_Definition_Clause): Check
2890 restriction No_Use_Of_Attribute before any rewritings have
2892 * sem_prag.adb (Analyze_Pragma): Check restriction
2893 No_Use_Of_Pragma before any rewritings have taken place.
2895 2016-04-18 Bob Duff <duff@adacore.com>
2897 * sem_ch6.adb (Is_Inline_Pragma): The pragma
2898 argument can be a selected component, which has no Chars field,
2899 so we need to deal with that case (use the Selector_Name).
2900 (Check_Inline_Pragma): We need to test Is_List_Member before
2901 calling In_Same_List, because in case of a library unit, they're
2902 not in lists, so In_Same_List fails an assertion.
2904 2016-04-18 Bob Duff <duff@adacore.com>
2906 * namet.ads, namet.adb: Add an Append that appends a
2907 Bounded_String onto a Bounded_String. Probably a little more
2908 efficient than "Append(X, +Y);". Also minor cleanup.
2909 (Append_Decoded, Append_Decoded_With_Brackets, Append_Unqualified,
2910 Append_Unqualified_Decoded): Make sure these work with non-empty
2912 * casing.ads, casing.adb (Set_Casing): Pass a Bounded_String
2913 parameter, defaulting to Global_Name_Buffer.
2914 * errout.ads, errout.adb (Adjust_Name_Case): Pass a
2915 Bounded_String parameter, no default.
2916 * exp_ch11.adb (Expand_N_Raise_Statement): Use local
2917 Bounded_String instead of Global_Name_Buffer.
2918 * exp_intr.ads, exp_intr.adb (Write_Entity_Name): Rename it
2919 to Append_Entity_Name, and pass a Bounded_String parameter,
2920 instead of using globals.
2921 (Add_Source_Info): Pass a Bounded_String parameter, instead of
2923 (Expand_Source_Info): Use local instead of globals.
2924 * stringt.ads, stringt.adb (Append): Add an Append procedure
2925 for appending a String_Id onto a Bounded_String.
2926 (String_To_Name_Buffer, Add_String_To_Name_Buffer): Rewrite in
2928 * sem_prag.adb (Set_Error_Msg_To_Profile_Name): Adjust for new
2929 Adjust_Name_Case parameter.
2930 * erroutc.adb, uname.adb: Don't pass D => Mixed_Case to
2931 Set_Casing; that's the default.
2932 * lib-xref-spark_specific.adb (Add_SPARK_Scope): Pretend that calls to
2933 protected subprograms are entry calls; otherwise it is not possible to
2934 distinguish them from regular subprogram calls.
2936 2016-04-18 Gary Dismukes <dismukes@adacore.com>
2938 * sem_ch13.adb (Has_Good_Profile): Improvement
2939 of error message. Now indicates subtype_mark of formal parameter
2940 rather than the formal's name, plus minor rewording.
2942 2016-04-18 Pascal Obry <obry@adacore.com>
2944 * adaint.c, adaint.h, s-os_lib.ads: Add new routine Current_Process_Id.
2946 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
2948 * stringt.adb, exp_ch6.adb, sem_ch13.adb: Minor reformatting.
2950 2016-04-18 Gary Dismukes <dismukes@adacore.com>
2952 * par-ch4.adb, sem_prag.adb: Minor reformatting.
2954 2016-04-18 Bob Duff <duff@adacore.com>
2956 * sinput.ads, sinput.adb (Build_Location_String): Take a
2957 parameter instead of using a global variable. The function
2958 version no longer destroys the Name_Buffer.
2959 * stringt.ads, stringt.adb (String_From_Name_Buffer): Take a
2960 parameter, which defaults to the Global_Name_Buffer, so some
2961 calls can avoid the global.
2962 * exp_ch11.adb, exp_intr.adb: Use new interfaces above
2963 to avoid using globals. All but one call to Build_Location_String
2964 avoids the global. Only one call to String_From_Name_Buffer
2967 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
2969 * namet.adb, namet.ads, exp_unst.adb: Minor reformatting.
2971 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
2973 * sem_eval.adb (Choice_Matches): Check the expression
2974 against the predicate values when the choice denotes a
2975 subtype with a static predicate.
2976 (Eval_Membership_Op): Code cleanup. Remove the suspicious guard which
2977 tests for predicates.
2978 (Is_OK_Static_Subtype): A subtype with a dynamic predicate
2979 is not static. (Is_Static_Subtype): A subtype with a dynamic
2980 predicate is not static.
2981 * sem_eval.ads (Is_OK_Static_Subtype): Update the comment on usage.
2982 (Is_Static_Subtype): Update the comment on usage.
2984 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
2986 * sem_prag.adb (Analyze_Input_Item): Allow
2987 generic formals to appear as initialization items.
2989 2016-04-18 Ed Schonberg <schonberg@adacore.com>
2991 * sem_ch13.adb (Analyze_Stream_TSS_Definition,
2992 Has_Good_Profile): Additional error message to indicate that
2993 the second parameter of the subprogram must be a first subtype.
2995 2016-04-18 Ed Schonberg <schonberg@adacore.com>
2997 * sem_ch6.adb (Analyze_Subprogram_Body_Helper, Is_Inline_Pragma):
2998 Use the pragma lookahead that determines whether a subprogram
2999 is to be inlined, when some level of backend optimization is
3001 * sem_ch12.ads, sem_ch12.adb (Add_Pending_Instantiation): Factorize
3002 code used to create an instance body when needed for inlining.
3003 * exp_ch6.adb (Expand_Call): When a call is to be inlined, and the
3004 call appears within an instantiation that is not a compilation
3005 unit, add a pending instantiation for the enclosing instance,
3006 so the backend can inline in turn the calls contained in the
3009 2016-04-18 Ed Schonberg <schonberg@adacore.com>
3011 * sem_prag.adb (Build_Pragma_Check_Equivalent): The mapping
3012 that relates operations of the parent type to the operations of
3013 the derived type has three distinct sources:
3014 a) explicit operations of the derived type carry an
3015 Overridden_Operation that designates the operation in the
3017 b) Implicit operations that are inherited by the derived type
3018 carry an alias that may be an explicit subprogram (in which case
3019 it may have an Overridden_ Operation indicator) or may also be
3020 inherited and carry its own alias.
3021 c) If the parent type is an interface, the operation of the
3022 derived type does not override, but the interface operation
3023 indicates the operation that implements it.
3024 * sem_prag.adb: Minor reformatting.
3025 * sem_prag.adb (Check_External_Property): Update
3026 the comment on usage. Reimplement.
3028 2016-04-18 Ed Schonberg <schonberg@adacore.com>
3030 * exp_ch5.adb (Expand_Assignment_Statement): In restricted
3031 profiles such as ZFP, ceiling priority is not available.
3033 2016-04-18 Bob Duff <duff@adacore.com>
3035 * namet-sp.ads: Minor typo fix, ironically in 'Spelling_Checker'.
3037 2016-04-18 Bob Duff <duff@adacore.com>
3039 * sem_elab.adb (Output_Calls): Use
3040 Get_Name_String, to clearly indicate that the global Name_Buffer
3041 is being used. The previous code used Is_Internal_Name, which
3042 returns a Boolean, but also has a side effect of setting the
3043 Name_Buffer. Then it called the other Is_Internal_Name, which uses
3044 the Name_Buffer for its input. And then it called Error_Msg_N,
3045 again using the Name_Buffer. We haven't eliminated the global
3046 usage here, but we've made it a bit clearer.
3047 This also allows us to have a side-effect-free version of
3049 * namet.ads, namet.adb: Provide a type Bounded_String, along with
3050 routines that can be used without using global variables. Provide
3051 Global_Name_Buffer so existing code can continue to use the
3052 global. Mark the routines that use globals as obsolete. New code
3053 shouldn't call the obsolete ones, and we should clean up existing
3054 code from time to time.
3055 Name_Find_Str is renamed as Name_Find.
3056 * namet.h: Changed as necessary to interface to the new version
3058 * bindgen.adb, exp_unst.adb: Name_Find_Str is renamed as
3061 2016-04-18 Yannick Moy <moy@adacore.com>
3063 * sem_util.adb, sem_util.ads (Has_Full_Default_Initialization): used
3064 outside of GNATprove, hence it should not be removed.
3066 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>

3099 2016-04-18 Bob Duff <duff@adacore.com>
3101 * a-cuprqu.ads: Change the representation of List_Type from a
3102 singly-linked list to a doubly-linked list. In addition, add a

3126 * sem_prag.adb (Collect_Inherited_Class_Wide_Conditions):
3127 Analyze the generated Check pragma for an inherited condition so
3128 that it does not freeze the dispatching type of the primitive
3129 operation, because it is pre-analyzed at the point of the

3131 done during regular expansion).
3133 2016-04-18 Vincent Celier <celier@adacore.com>
3135 * ali.ads: Increase the range of all _Id types to 100 millions.
3137 2016-04-18 Gary Dismukes <dismukes@adacore.com>

3163 * sem_prag.adb (Collect_Inherited_Class_Wide_Conditions): Insert
3164 generated pragmas after subprogram declaration, rather than in
3165 the corresponding subprogram body.
3166 * sem_ch6.adb (New_Overloaded_Entity): In GNATProve
3167 mode, if the operation is overridding, call
3168 Collect_Inherited_Class_Wide_Conditions to generate the

3187 detection when a selected component in the body of a synchronized
3188 type is a reference to an object of the same type declared
3189 elsewhere. The construct is legal if the prefix of the selected
3190 component includes an explicit dereference at any point.
