1342 procedure to compute the dimension vector of a scalar expression
1343 and compare it with the dimensions if its expected subtype. Used
1344 for the ultimate components of a multidimensional aggregate,

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

1466 consider a call when it appears within pragma Initial_Condition
1467 since the pragma is part of the elaboration statements of a
1468 package body and may only call external subprograms or subprograms
1469 whose body is already available.

1640 2016-04-21 Ed Schonberg <schonberg@adacore.com>
1642 * sem_ch13.adb (Add_Predicates): if the type is declared in
1643 an inner package it may be frozen outside of the package, and
1644 the generated pragma has not been analyzed yet, the expression
1645 for the predicate must be captured and added to the predicate
1646 function at this point.
1648 2016-04-21 Hristian Kirtchev <kirtchev@adacore.com>
1650 * contracts.adb (Analyze_Package_Body_Contract): Do not check
1651 for a missing package refinement because 1) packages do not have

1725 * lib-writ.adb (Write_ALI): Do not record in ali file units
1726 that are present in the files table but not analyzed. These
1727 units are present because they appear in the context of units
1728 named in limited_with clauses, and the unit being compiled does
1729 not depend semantically on them.
1731 2016-04-21 Ed Schonberg <schonberg@adacore.com>
1733 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Simplify code to
1734 create the procedure body for an function returning an array type,
1735 when generating C code. Reuse the subprogram body rather than
1736 creating a new one, both as an efficiency measure and because
1737 in an instance the body may contain global references that must
1738 be preserved.
1740 2016-04-21 Hristian Kirtchev <kirtchev@adacore.com>
1742 * sem_ch3.adb, exp_attr.adb, exp_ch6.adb, exp_aggr.adb: Minor

1794 2016-04-21 Ed Schonberg <schonberg@adacore.com>
1796 * sem_ch13.adb (Resolve_Name): Omit quantified expressions from
1797 resolution, because they introduce local names. Full resolution
1798 will take place when predicate function is constructed.
1800 2016-04-21 Arnaud Charlet <charlet@adacore.com>
1802 * exp_aggr.adb (Component_Not_OK_For_Backend): Refine previous
1803 change to take into account Per_Object_Constraint field rather
1804 than special casing strings.

1824 of a generic subpprogram that carries an Inline aspect. Place
1825 inline info on the anonymous subprogram that is constructed in
1826 the wrapper package.
1827 (Analyze_Pragma, case Pure): Do not check placement if pragma
1828 appears within an instantiation, which can be nested at any level.
1829 * sem_ch12.adb (Analyze_Instance_And_Renamings): Do not copy Freeze
1830 node from anonymous subprogram to its visible renaming. The
1831 freeze node will be constructed if the subprogram carries
1832 delayed aspects.
1833 (Set_Global): Preserve dimension information if present (from
1834 code reading).
1836 2016-04-21 Vasiliy Fofanov <fofanov@adacore.com>

1856 (Has_Non_Null_Abstract_State): New routine.
1857 * sem_ch7.adb (Unit_Requires_Body): Add local variable
1858 Requires_Body. A package declaring an abstract state requires
1859 a body only when the state is non-null and the package contains
1860 at least one other construct that requires completion in a body.
1861 * sem_util.adb (Mode_Is_Off): Removed.
1862 (Requires_State_Refinement): Remove an obsolete check. Code
1863 cleanup.
1865 2016-04-21 Bob Duff <duff@adacore.com>
1867 * sem_attr.adb (Analyze_Attribute): In processing
1868 the 'Old attribute, a warning is given for infinite recursion. Fix

1898 * sem_ch8.adb (Find_Selected_Component): If prefix has an
1899 access type and designated type is a limited view, introduce
1900 an explicit dereference before continuing the analysis, and
1901 set its type to the non-limited view of the designated type,
1902 if we are in context where it is available.
1904 2016-04-21 Ed Schonberg <schonberg@adacore.com>

1921 2016-04-21 Ed Schonberg <schonberg@adacore.com>
1923 * freeze.ads, freeze.adb (Freeze_Entity, Freeze_Before): Add
1924 boolean parameter to determine whether freezing an overloadable
1925 entity freezes its profile as well. This is required by
1926 AI05-019. The call to Freeze_Profile within Freeze_Entity is
1927 conditioned by the value of this flag, whose default is True.
1928 * sem_attr.adb (Resolve_Attribute, case 'Access): The attribute
1929 reference freezes the prefix, but it the prefix is a subprogram
1930 it does not freeze its profile.
1932 2016-04-21 Javier Miranda <miranda@adacore.com>
1934 * exp_util.adb (Build_Procedure_Form): No action needed for
1935 subprogram renamings since the backend can generate the call
1936 using the renamed subprogram. This leaves the tree more clean
1937 to the backend.

1948 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): If the body is
1949 created for SPARK_To_C, the entity must remain invisible so it
1950 does not overload subsequent references to the original function.
1951 * exp_ch6.adb (Build_Procedure_Body_Form, Replace_Returns):
1952 Handle Extended_Return_Statements by replacing it with a block
1953 with assignments and a simple return statement.
1954 * exp_util.adb (Build_Procedure_Form): Make procedure entity
1955 invisible after analyzing declaration, to prevent improper
1956 overloading.

1960 * sem_ch6.adb (Build_Subprogram_Declaration): Propagate the
1961 attribute Rewritten_For_C to the body since since the expander

2046 function, to construct the declaration of a predicate function
2047 at the end of the current declarative part rather than at the

2102 function that renames an instance of Unchecked_Conversion.
2103 * freeze.adb (Freeze_Subprogram): Generate the proper procedure

2153 entry family.
2155 2016-04-20 Arnaud Charlet <charlet@adacore.com>
2157 * a-cfdlli.ads (List): Type is no longer tagged, not needed. Move

2499 * exp_aggr.adb (Component_Count): Handle properly superflat
2500 arrays, i.e. empty arrays where Hi < Lo - 1, to ensure that the

2514 * checks.adb (Apply_Parameter_Aliasing_Checks): Do not apply
2515 the check if the type of the actual is By_Reference.
2517 2016-04-19 Arnaud Charlet <charlet@adacore.com>
2519 * sem_res.adb (Within_Subprogram_Call): Detect
2520 also nodes that appear in entry calls.
2521 (Resolve_Actuals, Insert_Default): Propagate
2522 dimension information if any, from default expression to the
2523 copy that appears in the list of actuals.

2539 2016-04-19 Eric Botcazou <ebotcazou@adacore.com>
2541 * sem_ch6.adb (Possible_Freeze): If the type is an incomplete
2542 CW type, then the subprogram must have a delayed freeze. This
2543 ensures that the backend can properly recover the full view when
2544 elaborating the access subprogram declaration.
2546 2016-04-19 Ed Schonberg <schonberg@adacore.com>
2548 * sem_attr.adb (Resolve_Attribute, case 'Access): Freeze
2549 overloadable entity if originally overloaded.

2557 clean up.
2559 2016-04-19 Arnaud Charlet <charlet@adacore.com>
2561 * sem_util.adb (Copy_Node_With_Replacement):
2562 use Set_Comes_From_Source instead of directly manipulating
2563 internals of the node table.
2564 * sem_util.adb (Within_Scope): refactored to remove duplicated code.
2565 * sem_aux.adb (Get_Rep_Pragma,
2566 Subprogram_Body_Entity, Subprogram_Spec): declare variables that
2567 do not change as constants and initialize them in the declaration.
2568 (Get_Rep_Pragma, Subprogram_Body_Entity, Subprogram_Spec): declare
2569 variables that do not change as constants and initialize them
2570 in the declaration.
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.
2586 * sem_util.ads, sem_util.adb (Current_Scope_No_Loops): New routine.
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
2603 -P" invoke "gprbuild -b" Make "gnat link -P" invoke "gprbuild

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.

2642 * einfo.adb (Overridden_Operation): assert that
2643 function is called for valid arguments.

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.

2712 * exp_ch4.adb, gnat1drv.adb, opt.ads, sem_res.adb
2713 (Minimize_Expression_With_Actions): New flag.
2714 (Adjust_Global_Switches): Set Minimize_Expression_With_Actions
2715 when generating C.
2716 (Resolve_Short_Circuit): Redo previous change
2717 using Minimize_Expression_With_Actions.
2718 (Expand_N_If_Expression,
2719 Expand_Short_Circuit_Operator): Restore old code to avoid
2720 Expression_With_Actions when Minimize_Expression_With_Actions
2721 is set.
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
2765 or implicit).
2767 2016-04-18 Arnaud Charlet <charlet@adacore.com>
2769 * osint-c.ads, osint-c.adb (Delete_C_File, Delete_H_File): New.

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
2779 expression.
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
2802 checks are enabled.
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
2857 a reader is ready.
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
2878 flag for an aspect.
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
2883 a pragma.
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
2891 taken place.
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
2911 buffers.
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
2922 using globals.
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
2927 terms of Append.
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
2965 avoids it.
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
3000 required.
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
3007 inlined body.
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
3016 ancestor.
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
3048 Is_Internal_Name.
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
3057 of Namet.
3058 * bindgen.adb, exp_unst.adb: Name_Find_Str is renamed as
3059 Name_Find.
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>
3068 * sem_prag.adb (Analyze_Refinement_Clause):
3069 The refinement of an external abstract state can now mention
3070 non-external constituents.
3071 (Check_External_Property): Update all SPARK RM references.
3073 2016-04-18 Bob Duff <duff@adacore.com>
3075 * exp_intr.adb: Remove some duplicated code.
3077 2016-04-18 Yannick Moy <moy@adacore.com>
3079 * a-nudira.adb, a-nudira.ads, a-nuflra.adb, a-nuflra.ads: Mark
3080 package spec and body out of SPARK.

3086 2016-04-18 Johannes Kanig <kanig@adacore.com>
3088 * gnat1drv.adb (Gnat1drv): Force loading of System
3089 unit for SPARK.
3091 2016-04-18 Bob Duff <duff@adacore.com>
3093 * a-cuprqu.adb: Correction to previous change. If a new node
3094 is inserted at the front of the queue (because it is higher
3095 priority than the previous front node), we need to update
3096 Header.Next_Unequal -- not just in the case where the queue was
3097 previously empty.
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
3103 pointer Next_Unequal, which points past a possibly-long chain
3104 of equal-priority items. This increases efficiency, especially
3105 in the case of many equal-priority items.
3106 * a-cuprqu.adb (Dequeue, Enqueue): Rewrite algorithms to take
3107 advantage of new data structure.
3108 (Finalize): Rewrite in terms of Dequeue, for simplicity.
3110 2016-04-18 Yannick Moy <moy@adacore.com>
3112 * contracts.adb (Analyze_Object_Contract,
3113 Analyze_Protected_Contract): Remove tests performed in GNATprove.
3114 * sem_util.adb, sem_util.ads (Has_Full_Default_Initialization):
3115 Remove query for tests performed in GNATprove.
3117 2016-04-18 Ed Schonberg <schonberg@adacore.com>
3119 * sem_aggr.adb (Resolve_Record_Aggregate): If
3120 Warn_On_Redundant_Constructs is enabled, report a redundant box
3121 association that does not cover any components, as it done for
3122 redundant others associations in case statements.
3124 2016-04-18 Ed Schonberg <schonberg@adacore.com>
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
3130 subprogram declaration (and not in the subprogram body, as is
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>
3139 * sem_warn.adb (Check_References): Change warning to suggest
3140 using pragma Export rather than saying "volatile has no effect".
3142 2016-04-18 Bob Duff <duff@adacore.com>
3144 * g-souinf.ads (Compilation_ISO_Date): New function to return
3145 the current date in ISO form.
3146 * exp_intr.adb (Expand_Source_Info, Add_Source_Info): Expand
3147 a call to Compilation_ISO_Date into a string literal containing
3148 the current date in ISO form.
3149 * exp_intr.ads (Add_Source_Info): Improve documentation.
3150 * sem_intr.adb (Check_Intrinsic_Subprogram): Recognize
3151 Compilation_ISO_Date.
3152 * snames.ads-tmpl (Name_Compilation_ISO_Date): New Name_Id.
3154 2016-04-18 Eric Botcazou <ebotcazou@adacore.com>
3156 * layout.adb (Set_Elem_Alignment): Extend setting of alignment
3157 to subtypes that are not first subtypes.
3159 2016-04-18 Ed Schonberg <schonberg@adacore.com>
3161 * sem_prag.ads (Collect_Inherited_Class_Wide_Conditions):
3162 Simplify interface.
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
3169 corresponding pragmas immediately after the corresponding
3170 subprogram declaration.
3172 2016-04-18 Arnaud Charlet <charlet@adacore.com>
3174 * spark_xrefs.ads (Xref_Index, Scope_Index, File_Index): restrict
3175 type to natural numbers.
3176 (Stype): document code characters for concurrent entities.
3178 2016-04-18 Olivier Hainque <hainque@adacore.com>
3180 * targparm.ads: Update the Frontend_Exceptions default internal
3181 value.
3182 (Frontend_Exceptions_On_Target): Change default value to True.
3184 2016-04-18 Ed Schonberg <schonberg@adacore.com>
3186 * sem_ch4.adb (Analyze_Selected_Component): Refine error
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.
3192 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
3194 * sem_ch3.adb (Analyze_Object_Declaration): Do not consider
3195 internally generated expressions when trying to determine whether
3196 a formal parameter of a tagged type subject to Extensions_Visible
3197 False is used to initialize an object.
3198 * sem_ch4.adb (Analyze_Type_Conversion): Do not consider
3199 internally generated expressions when trying to determine whether
3200 a formal parameter of a tagged type subject to Extensions_Visible
3201 False is used in a type conversion.
3203 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
3205 * sem_res.adb (Is_Protected_Operation_Call):
3206 Add guards to account for a non-decorated selected component.
3208 2016-04-18 Yannick Moy <moy@adacore.com>
3210 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Improve
3211 implementation of Body_Has_SPARK_Mode_On.
3212 * sem_prag.adb, sem_prag.ads (Get_SPARK_Mode_From_Annotation):
3213 New function replacing previous Get_SPARK_Mode_From_Pragma, that
3214 deals also with aspects.
3215 (Get_SPARK_Mode_Type): Make function internal again.
3216 * inline.adb, sem_ch7.adb, sem_util.adb: Use new
3217 Get_SPARK_Mode_From_Annotation.
3219 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
3221 * contracts.adb (Analyze_Object_Contract): Update references to
3222 SPARK RM.

3229 (Check_Ghost_Refinement): New routine. (Is_OK_Ghost_Context):
3230 Update references to SPARK RM. (Is_OK_Pragma): Update references
3231 to SPARK RM. Predicates are now a valid context for references
3232 to Ghost entities.
3233 * ghost.ads (Check_Ghost_Derivation): Removed.
3234 (Check_Ghost_Overriding): Update the comment on usage.
3235 (Check_Ghost_Primitive): New routine.

3243 of a tagged type and its primitive agree.
3244 * sem_prag.adb (Analyze_Pragma): Update references to SPARK
3245 RM. Move the verification of pragma Assertion_Policy Ghost
3246 to the proper place. Remove the now obsolete check related
3247 to Ghost derivations.
3248 (Collect_Constituent): Add a call to Check_Ghost_Refinement.
3249 * sem_res.adb (Resolve_Actuals): Update references to SPARK RM.
3251 2016-04-18 Eric Botcazou <ebotcazou@adacore.com>
3253 * layout.adb: Fix more minor typos in comments.
3255 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>

3259 2016-04-18 Ed Schonberg <schonberg@adacore.com>
3261 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): In GNATprove
3262 mode, collect inherited class-wide conditions to generate the
3263 corresponding pragmas.
3264 * sem_prag.ads (Build_Pragma_Check_Equivalent): Moved from contracts
3265 * contracts.adb (Collect_Inherited_Class_Wide_Conditions): New
3266 procedure for overriding subprograms, used to generate the pragmas
3267 corresponding to an inherited class- wide pre- or postcondition.
3268 * sem_prag.adb (Build_Pragma_Check_Equivalent): moved here
3269 from contracts.adb (Replace_Condition_Entities): Subsidiary
3270 Build_Pragma_Check_Equivalent, to implement the proper semantics
3271 of inherited class-wide conditions, as given in AI12-0113.
3272 (Process_Class_Wide_Condition): Removed.
3273 (Collect_Inherited_Class_Wide_Conditions): Iterate over pragmas
3274 in contract of subprogram, to collect inherited class-wide
3275 conditions.
3276 (Build_Pragma_Check_Equivalent): Moved to sem_prag.adb
3278 2016-04-18 Yannick Moy <moy@adacore.com>
3280 * a-calend.adb (Ada.Calendar): Mark package body as SPARK_Mode Off.
3281 * a-calend.ads (Ada.Calendar): Mark package spec as
3282 SPARK_Mode and add synchronous external abstract state Clock_Time.
3284 2016-04-18 Yannick Moy <moy@adacore.com>
3286 * sem_res.adb (Resolve_Call): Prevent inlining of
3287 calls inside expression functions. Factor previous code issuing
3288 errors to call Cannot_Inline instead, which does appropriate
3289 processing of message for GNATprove.
3291 2016-04-18 Arnaud Charlet <charlet@adacore.com>
3293 * einfo.ads, sem_ch3.adb, sem_ch8.adb, osint-l.adb, rtsfind.adb,
3294 osint-b.adb: Cleanups.
3296 2016-04-18 Yannick Moy <moy@adacore.com>
3298 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Only create
3299 body to inline in GNATprove mode when SPARK_Mode On applies to
3300 subprogram body.
3301 * sem_prag.adb, sem_prag.ads (Get_SPARK_Mode_Type): Make function
3302 public.
3304 2016-04-18 Eric Botcazou <ebotcazou@adacore.com>
3306 * layout.adb: Fix minor typo in comment.

3310 2016-04-18 Ed Schonberg <schonberg@adacore.com>
3312 * sem_disp.adb (Check_Dispatching_Call): Major rewriting to
3313 handle some complex cases of tag indeterminate calls that are
3314 actuals in other dispatching calls that are themselves tag
3315 indeterminate.
3316 (Check_Dispatching_Context): Add parameter to support recursive
3317 check for an enclosing construct that may provide a tag for a
3318 tag-indeterminate call.
3320 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
3322 * sem_prag.adb (Analyze_Depends_In_Decl_Part):
3323 Add global variables Task_Input_Seen and Task_Output_Seen.
3324 (Analyze_Global_Item): Detect an illegal use of the current
3325 instance of a single protected/task type in a global annotation.
3326 (Analyze_Input_Output): Inputs and output related to the current
3327 instance of a task unit are now tracked.

3329 the presence of the current instance of a task unit only when
3330 one input/output is available. (Current_Task_Instance_Seen):
3331 New routine.
3332 (Is_CCT_Instance): New parameter profile. Update
3333 the comment on usage. The routine now properly recognizes several
3334 cases related to single protected/task types.
3336 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
3338 * freeze.adb (Freeze_Entity): Use New_Freeze_Node
3339 to create a brand new freeze node. This handles a case where an
3340 ignored Ghost context is freezing something which is not ignored
3341 Ghost and whose freeze node should not be removed from the tree.
3342 (New_Freeze_Node): New routine.
3344 2016-04-18 Jerome Lambourg <lambourg@adacore.com>
3346 * sigtramp.h (__gnat_set_is_vxsim) New function to
3347 tell sigtramp-vxworks to handle vxsim signal contexts. *
3348 sigtramp-vxworks.c (__gnat_sigtramp) Take into account the
3349 differences in the sigcontext structure between the expected
3350 regular x86 or x86_64 ones and the ones received in case of
3351 exexution on the vxworks simulator.
3352 * init.c: also compute is_vxsim in case of x86_64-vx7 target. Provide
3353 this information to sigtramp-vxworks.c. Remove the old mechanism for
3354 vxsim.
3355 * init-vxsim.c, sigtramp-vxworks-vxsim.c: remove, now obsolete.
3357 2016-04-18 Eric Botcazou <ebotcazou@adacore.com>
3359 * exp_ch3.adb (Inline_Init_Proc): New function returning
3360 whether the initialization procedure of a type should be
3361 inlined. Return again True for controlled type themselves.
3362 (Build_Array_Init_Proc): Call it to set Set_Is_Inlined on Init_Proc.
3363 (Build_Record_Init_Proc): Likewise.
3365 2016-04-18 Arnaud Charlet <charlet@adacore.com>
3367 * gnatvsn.ads (Library_Version): Bump to 7.
3369 2016-04-18 Ed Schonberg <schonberg@adacore.com>
3371 * sem_ch6.adb (Analyze_Expression_Function): Set Inlined flag
3372 on the entity of a subprogram declaration that is completed by
3373 an expression function.
3375 2016-04-18 Ed Schonberg <schonberg@adacore.com>
3377 * sem_util.adb (Is_Current_Instance): A entity given by a subtype
3378 declaration can appear in an aspect specification for a dynamic
3379 predicate, and a pragma for aspect Predicate_Failure.
3380 * exp_util.adb (Replace_Subtype_References): Replace current
3381 occurrences of the subtype to which a dynamic predicate applies,
3382 byt the expression that triggers a predicate check. Needed to
3383 implement new aspect Predicate_Failure.
3385 2016-04-18 Arnaud Charlet <charlet@adacore.com>
3387 * a-intsig.ads, a-intsig.adb: Removed, no longer used.

3404 * exp_ch3.adb (Build_Record_Init_Proc): Do not mark the procedure
3405 as to be inlined if the type needs finalization.
3407 2016-04-18 Jerome Lambourg <lambourg@adacore.com>
3409 * sigtramp-vxworks-target.inc: sigtramp-vxworks: force the stack
3410 alignment for x86_64.
3411 * init.c: Better fix for guard page reset on x86_64-vx7.
3412 Do not try to retrieve the page that actually raised
3413 the signal as the probing mechanism used on x86_64 do not allow
3414 such retrieval. We thus just test if the guard page is active,
3415 and re-activate it if not.
3417 2016-04-18 Arnaud Charlet <charlet@adacore.com>
3419 * a-sytaco.adb (Suspension_Object): Aspect Default_Initial_Condition
3420 added.
3422 2016-04-18 Jerome Lambourg <lambourg@adacore.com>
3424 * affinity.c: Use the proper type for task id.
