89 function, to construct the declaration of a predicate function

562 * sem_res.adb (Within_Subprogram_Call): Detect
563 also nodes that appear in entry calls.

580 to SPARK RM in both comment and error message.
582 2016-04-19 Eric Botcazou <ebotcazou@adacore.com>
584 * sem_ch6.adb (Possible_Freeze): If the type is an incomplete
585 CW type, then the subprogram must have a delayed freeze. This
586 ensures that the backend can properly recover the full view when
587 elaborating the access subprogram declaration.
589 2016-04-19 Ed Schonberg <schonberg@adacore.com>
591 * sem_attr.adb (Resolve_Attribute, case 'Access): Freeze

604 * sem_util.adb (Copy_Node_With_Replacement):
605 use Set_Comes_From_Source instead of directly manipulating
606 internals of the node table.
607 * sem_util.adb (Within_Scope): refactored to remove duplicated code.
608 * sem_aux.adb (Get_Rep_Pragma,
609 Subprogram_Body_Entity, Subprogram_Spec): declare variables that
610 do not change as constants and initialize them in the declaration.

612 variables that do not change as constants and initialize them
615 2016-04-19 Ed Schonberg <schonberg@adacore.com>
617 * sem_res.adb (Resolve_Entry_Call): If the entry has
618 preconditions it is rewritten by means of a wrapper that
619 incorporates the original call. Before rewriting generate a
620 reference to the entry being called to prevent spurious warnings
621 and provide correct cross-reference information.
623 2016-04-19 Hristian Kirtchev <kirtchev@adacore.com>
625 * sem_disp.adb (Check_Dispatching_Context): Code cleanup. Add

633 * sem_elab.adb (Check_A_Call): There are cases where we have No
634 (Ent) after the Alias loop, even when there was no previous error,
635 so we can't assert that there was an error.
637 2016-04-19 Ed Schonberg <schonberg@adacore.com>
639 * sem_attr.adb (Analyze_Access_Attribute, OK_Self_Reference):
640 Reject use of type name as a prefix to 'access within an aggregate
641 in a context that is not the declarative region of a type.
643 2016-04-19 Vincent Celier <celier@adacore.com>
645 * gnatcmd.adb: Make "gnat ls -P" invoke gprls Make "gnat bind
646 -P" invoke "gprbuild -b" Make "gnat link -P" invoke "gprbuild
647 -l" Fail if the invocation is "gnat find -P" or "gnat xref -P"
648 Remove anything related to project files
649 * g-mbdira.adb: minor whitespace cleanup
650 * g-spipat.adb: minor removal of extra spaces after closing paren
652 2016-04-19 Ed Schonberg <schonberg@adacore.com>
654 * exp_ch6.adb (Expand_Actuals): If post-statements are present
655 and the enclosing context is a function call or indexing, build
656 an Expression_With_Actions for the call.
658 2016-04-19 Hristian Kirtchev <kirtchev@adacore.com>
660 * lib-writ.adb (Write_With_Lines): Code cleanup. Do not generate
661 a with line for an ignored Ghost unit.
662 * sem_ch7.adb (Analyze_Package_Declaration): Add local constant
663 Par. A child package is Ghost when its parent is Ghost.
664 * sem_prag.adb (Analyze_Pragma): Pragma Ghost can now apply to
665 a subprogram declaration that acts as a compilation unit.
667 2016-04-18 Michael Matz <matz@suse.de>

737 2016-04-18 Gary Dismukes <dismukes@adacore.com>
739 * exp_ch4.adb (Optimize_Length_Comparison): Return immediately
740 in the case of AAMP (same as for use of the -gnatd.P switch) to
741 suppress this optimization, which avoids creating a dependence
742 on the 64-bit arithmetic package.
744 2016-04-18 Arnaud Charlet <charlet@adacore.com>
746 * exp_ch4.adb: Update comment.
748 2016-04-18 Eric Botcazou <ebotcazou@adacore.com>

769 Stderr_File): Close local file descriptors when no longer needed.
771 2016-04-18 Ed Schonberg <schonberg@adacore.com>
773 * sem_ch5.adb (Analyze_Iterator_Specification): Remove SPARK
774 mode check that the type of the cursor in an iteration over
775 a formal container is not volatile. The proper check on the
776 element type is done elsewhere.
778 2016-04-18 Ed Schonberg <schonberg@adacore.com>
780 * sem_ch6.adb (Process_Formals): Do not set a delay freeze on
781 a subprogram that returns a class-wide type, if the subprogram
782 is a compilation unit, because otherwise gigi will treat the
783 subprogram as external, leading to link errors.
785 2016-04-18 Arnaud Charlet <charlet@adacore.com>
787 * sem_res.adb (Resolve_Short_Circuit): Do not use
788 expression-with-actions when generating C.

800 parameters to actuals.
802 2016-04-18 Ed Schonberg <schonberg@adacore.com>
804 * sem_ch5.adb (Get_Cursor_Type): If iterator type is a derived
805 type, the cursor is declared in the scope of the parent type.
806 (Analyze_Parameter_Specification): A qualified expression with an
807 iterator type indicates an iteration over a container (explicit
810 2016-04-18 Arnaud Charlet <charlet@adacore.com>
812 * osint-c.ads, osint-c.adb (Delete_C_File, Delete_H_File): New.
813 * gnat1drv.adb (Gnat1drv): Delete old C files before regenerating them.
814 * debug.adb: Reserve -gnatd.4 to force generation of C files.
816 2016-04-18 Yannick Moy <moy@adacore.com>
818 * sem_eval.adb (Eval_Arithmetic_Op): Do not issue error on static
819 division by zero, instead possibly issue a warning.
820 * sem_res.adb (Resolve_Arithmetic_Op): Do not issue error on
821 static division by zero, instead add check flag on original
823 * sem_util.adb, sem_util.ads (Compile_Time_Constraint_Error):
824 Only issue error when both SPARK_Mode is On and Warn is False.
826 2016-04-18 Yannick Moy <moy@adacore.com>
828 * checks.adb (Apply_Scalar_Range_Check): Force
829 warning instead of error when SPARK_Mode is On, on index out of
830 bounds, and set check flag for GNATprove.
832 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
834 * sem_prag.adb (Check_In_Out_States.Check_Constituent_Usage):
835 Update the comment on usage. Reimplemented.
836 (Check_Input_States.Check_Constituent_Usage): Update the comment
837 on usage. A Proof_In constituent can now refine an Input state
838 as long as there is at least one Input constituent present.
840 2016-04-18 Ed Schonberg <schonberg@adacore.com>
842 * sem_ch6.adb (Check_Inline_Pragma): Use the Sloc of the
843 body id as the sloc of the entity in the generated subprogram
844 declaration, to avoid spurious conformance errors when style
847 2016-04-18 Ed Schonberg <schonberg@adacore.com>
849 * sem_ch4.adb (Analyze_Selected_Component, Has_Dereference):
850 Refine check on illegal calls to entities within a task body,
851 when the entity is declared in an object of the same type. In
852 a generic context there might be no explicit dereference but if
853 the prefix includes an access type the construct is legal.
855 2016-04-18 Arnaud Charlet <charlet@adacore.com>
857 * rtsfind.ads, rtsfind.adb (RE_Id, RE_Unit_Table): add
860 2016-04-18 Bob Duff <duff@adacore.com>
862 * sem_prag.adb (Check_Arg_Is_Local_Name): Don't do the check
863 if the pragma came from an aspect specification.
865 2016-04-18 Gary Dismukes <dismukes@adacore.com>
867 * gnat1drv.adb, contracts.adb: Minor reformatting and wording fixes.
869 2016-04-18 Ed Schonberg <schonberg@adacore.com>
871 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): To suppress
872 superfluous conformance check on an inlined body with a previous
873 spec, use the fact that the generated declaration does not come
874 from source. We must treat the entity as coming from source to
875 enable some back-end inlining when pragma appears after the body.
877 2016-04-18 Gary Dismukes <dismukes@adacore.com>
879 * lib-xref-spark_specific.adb, par-ch2.adb, errout.ads,
880 exp_intr.adb: Minor reformatting and typo corrections.
882 2016-04-18 Ed Schonberg <schonberg@adacore.com>
884 * sem_ch6.adb: Code cleanup.
886 2016-04-18 Thomas Quinot <quinot@adacore.com>

895 2016-04-18 Bob Duff <duff@adacore.com>
897 * s-fileio.adb (Fopen_Mode): If Mode = Out_File, and the file
898 exists, and it's a fifo, we use "w" as the open string instead of
899 "r+". This is necessary to make a write to the fifo block until
902 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
904 * sem_attr.adb (Denote_Same_Function): Account
905 for a special case where a primitive of a tagged type inherits
906 a class-wide postcondition from a parent type.
908 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
910 * par-ch2.adb (P_Expression_Or_Reserved_Word): New routine.
911 (P_Pragma): Signal Scan_Pragma_Argument_Association when the use
912 of reserved words is OK.
913 (Scan_Pragma_Argument_Association):
914 Add new formal Reserved_Words_OK and update the comment on
915 usage. Code cleanup. Parse an expression or a reserved word in
916 identifier form for pragmas Restriction_Warnings and Restrictions
918 * restrict.adb (Check_Restriction_No_Use_Of_Attribute):
919 Reimplemented. (Check_Restriction_No_Use_Of_Pragma): Code cleanup.
920 (Set_Restriction_No_Specification_Of_Aspect): Properly set the warning
922 (Set_Restriction_No_Use_Of_Attribute): Properly set the warning
923 flag for an attribute. (Set_Restriction_No_Use_Of_Entity):

930 * sem_attr.adb (Analyze_Attribute): Check restriction
932 * sem_ch13.adb (Analyze_Attribute_Definition_Clause): Check
933 restriction No_Use_Of_Attribute before any rewritings have
935 * sem_prag.adb (Analyze_Pragma): Check restriction
936 No_Use_Of_Pragma before any rewritings have taken place.
938 2016-04-18 Bob Duff <duff@adacore.com>
940 * sem_ch6.adb (Is_Inline_Pragma): The pragma
941 argument can be a selected component, which has no Chars field,
942 so we need to deal with that case (use the Selector_Name).
943 (Check_Inline_Pragma): We need to test Is_List_Member before
944 calling In_Same_List, because in case of a library unit, they're
945 not in lists, so In_Same_List fails an assertion.
947 2016-04-18 Bob Duff <duff@adacore.com>
949 * namet.ads, namet.adb: Add an Append that appends a
950 Bounded_String onto a Bounded_String. Probably a little more
951 efficient than "Append(X, +Y);". Also minor cleanup.
952 (Append_Decoded, Append_Decoded_With_Brackets, Append_Unqualified,
953 Append_Unqualified_Decoded): Make sure these work with non-empty
955 * casing.ads, casing.adb (Set_Casing): Pass a Bounded_String
956 parameter, defaulting to Global_Name_Buffer.
957 * errout.ads, errout.adb (Adjust_Name_Case): Pass a
958 Bounded_String parameter, no default.
959 * exp_ch11.adb (Expand_N_Raise_Statement): Use local
960 Bounded_String instead of Global_Name_Buffer.
961 * exp_intr.ads, exp_intr.adb (Write_Entity_Name): Rename it
962 to Append_Entity_Name, and pass a Bounded_String parameter,
963 instead of using globals.
964 (Add_Source_Info): Pass a Bounded_String parameter, instead of
966 (Expand_Source_Info): Use local instead of globals.
967 * stringt.ads, stringt.adb (Append): Add an Append procedure
968 for appending a String_Id onto a Bounded_String.
969 (String_To_Name_Buffer, Add_String_To_Name_Buffer): Rewrite in
971 * sem_prag.adb (Set_Error_Msg_To_Profile_Name): Adjust for new
972 Adjust_Name_Case parameter.
973 * erroutc.adb, uname.adb: Don't pass D => Mixed_Case to
974 Set_Casing; that's the default.
975 * lib-xref-spark_specific.adb (Add_SPARK_Scope): Pretend that calls to
976 protected subprograms are entry calls; otherwise it is not possible to
977 distinguish them from regular subprogram calls.
979 2016-04-18 Gary Dismukes <dismukes@adacore.com>
981 * sem_ch13.adb (Has_Good_Profile): Improvement
982 of error message. Now indicates subtype_mark of formal parameter
983 rather than the formal's name, plus minor rewording.

987 * adaint.c, adaint.h, s-os_lib.ads: Add new routine Current_Process_Id.

993 2016-04-18 Gary Dismukes <dismukes@adacore.com>
995 * par-ch4.adb, sem_prag.adb: Minor reformatting.
997 2016-04-18 Bob Duff <duff@adacore.com>
999 * sinput.ads, sinput.adb (Build_Location_String): Take a
1000 parameter instead of using a global variable. The function
1001 version no longer destroys the Name_Buffer.
1002 * stringt.ads, stringt.adb (String_From_Name_Buffer): Take a
1003 parameter, which defaults to the Global_Name_Buffer, so some
1004 calls can avoid the global.
1005 * exp_ch11.adb, exp_intr.adb: Use new interfaces above
1006 to avoid using globals. All but one call to Build_Location_String
1007 avoids the global. Only one call to String_From_Name_Buffer
1010 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
1012 * namet.adb, namet.ads, exp_unst.adb: Minor reformatting.
1014 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
1016 * sem_eval.adb (Choice_Matches): Check the expression
1017 against the predicate values when the choice denotes a
1018 subtype with a static predicate.
1019 (Eval_Membership_Op): Code cleanup. Remove the suspicious guard which
1020 tests for predicates.
1021 (Is_OK_Static_Subtype): A subtype with a dynamic predicate
1022 is not static. (Is_Static_Subtype): A subtype with a dynamic
1023 predicate is not static.
1024 * sem_eval.ads (Is_OK_Static_Subtype): Update the comment on usage.
1025 (Is_Static_Subtype): Update the comment on usage.
1027 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
1029 * sem_prag.adb (Analyze_Input_Item): Allow
1030 generic formals to appear as initialization items.
1032 2016-04-18 Ed Schonberg <schonberg@adacore.com>
1034 * sem_ch13.adb (Analyze_Stream_TSS_Definition,
1035 Has_Good_Profile): Additional error message to indicate that
1036 the second parameter of the subprogram must be a first subtype.
1038 2016-04-18 Ed Schonberg <schonberg@adacore.com>
1040 * sem_ch6.adb (Analyze_Subprogram_Body_Helper, Is_Inline_Pragma):
1041 Use the pragma lookahead that determines whether a subprogram
1042 is to be inlined, when some level of backend optimization is
1044 * sem_ch12.ads, sem_ch12.adb (Add_Pending_Instantiation): Factorize
1045 code used to create an instance body when needed for inlining.
1046 * exp_ch6.adb (Expand_Call): When a call is to be inlined, and the
1047 call appears within an instantiation that is not a compilation
1048 unit, add a pending instantiation for the enclosing instance,
1049 so the backend can inline in turn the calls contained in the
1052 2016-04-18 Ed Schonberg <schonberg@adacore.com>
1054 * sem_prag.adb (Build_Pragma_Check_Equivalent): The mapping
1055 that relates operations of the parent type to the operations of
1056 the derived type has three distinct sources:
1057 a) explicit operations of the derived type carry an
1058 Overridden_Operation that designates the operation in the
1060 b) Implicit operations that are inherited by the derived type
1061 carry an alias that may be an explicit subprogram (in which case
1062 it may have an Overridden_ Operation indicator) or may also be
1063 inherited and carry its own alias.
1064 c) If the parent type is an interface, the operation of the
1065 derived type does not override, but the interface operation
1066 indicates the operation that implements it.
1067 * sem_prag.adb: Minor reformatting.
1068 * sem_prag.adb (Check_External_Property): Update
1069 the comment on usage. Reimplement.
1071 2016-04-18 Ed Schonberg <schonberg@adacore.com>
1073 * exp_ch5.adb (Expand_Assignment_Statement): In restricted
1074 profiles such as ZFP, ceiling priority is not available.
1076 2016-04-18 Bob Duff <duff@adacore.com>
1078 * namet-sp.ads: Minor typo fix, ironically in 'Spelling_Checker'.
1080 2016-04-18 Bob Duff <duff@adacore.com>
1082 * sem_elab.adb (Output_Calls): Use
1083 Get_Name_String, to clearly indicate that the global Name_Buffer
1084 is being used. The previous code used Is_Internal_Name, which
1085 returns a Boolean, but also has a side effect of setting the
1086 Name_Buffer. Then it called the other Is_Internal_Name, which uses
1087 the Name_Buffer for its input. And then it called Error_Msg_N,
1088 again using the Name_Buffer. We haven't eliminated the global
1089 usage here, but we've made it a bit clearer.
1090 This also allows us to have a side-effect-free version of
1092 * namet.ads, namet.adb: Provide a type Bounded_String, along with
1093 routines that can be used without using global variables. Provide
1094 Global_Name_Buffer so existing code can continue to use the
1095 global. Mark the routines that use globals as obsolete. New code
1096 shouldn't call the obsolete ones, and we should clean up existing
1097 code from time to time.
1098 Name_Find_Str is renamed as Name_Find.
1099 * namet.h: Changed as necessary to interface to the new version
1101 * bindgen.adb, exp_unst.adb: Name_Find_Str is renamed as
1104 2016-04-18 Yannick Moy <moy@adacore.com>
1106 * sem_util.adb, sem_util.ads (Has_Full_Default_Initialization): used
1107 outside of GNATprove, hence it should not be removed.
1109 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
1111 * sem_prag.adb (Analyze_Refinement_Clause):
1112 The refinement of an external abstract state can now mention

1134 2016-04-18 Bob Duff <duff@adacore.com>
1136 * a-cuprqu.adb: Correction to previous change. If a new node
1137 is inserted at the front of the queue (because it is higher
1138 priority than the previous front node), we need to update
1139 Header.Next_Unequal -- not just in the case where the queue was
1142 2016-04-18 Bob Duff <duff@adacore.com>
1144 * a-cuprqu.ads: Change the representation of List_Type from a
1145 singly-linked list to a doubly-linked list. In addition, add a
1146 pointer Next_Unequal, which points past a possibly-long chain
1147 of equal-priority items. This increases efficiency, especially
1148 in the case of many equal-priority items.
1149 * a-cuprqu.adb (Dequeue, Enqueue): Rewrite algorithms to take
1150 advantage of new data structure.
1151 (Finalize): Rewrite in terms of Dequeue, for simplicity.

1163 Warn_On_Redundant_Constructs is enabled, report a redundant box
1164 association that does not cover any components, as it done for
1165 redundant others associations in case statements.

1169 * sem_prag.adb (Collect_Inherited_Class_Wide_Conditions):
1170 Analyze the generated Check pragma for an inherited condition so
1171 that it does not freeze the dispatching type of the primitive
1172 operation, because it is pre-analyzed at the point of the
1173 subprogram declaration (and not in the subprogram body, as is
1174 done during regular expansion).
1176 2016-04-18 Vincent Celier <celier@adacore.com>
1178 * ali.ads: Increase the range of all _Id types to 100 millions.
1180 2016-04-18 Gary Dismukes <dismukes@adacore.com>
1182 * sem_warn.adb (Check_References): Change warning to suggest
1183 using pragma Export rather than saying "volatile has no effect".

1200 to subtypes that are not first subtypes.
1202 2016-04-18 Ed Schonberg <schonberg@adacore.com>
1204 * sem_prag.ads (Collect_Inherited_Class_Wide_Conditions):
1206 * sem_prag.adb (Collect_Inherited_Class_Wide_Conditions): Insert
1207 generated pragmas after subprogram declaration, rather than in
1208 the corresponding subprogram body.
1209 * sem_ch6.adb (New_Overloaded_Entity): In GNATProve
1210 mode, if the operation is overridding, call
1211 Collect_Inherited_Class_Wide_Conditions to generate the
1212 corresponding pragmas immediately after the corresponding
1213 subprogram declaration.

1227 2016-04-18 Ed Schonberg <schonberg@adacore.com>
1229 * sem_ch4.adb (Analyze_Selected_Component): Refine error
1230 detection when a selected component in the body of a synchronized
1231 type is a reference to an object of the same type declared
1232 elsewhere. The construct is legal if the prefix of the selected
1233 component includes an explicit dereference at any point.
1235 2016-04-18 Hristian Kirtchev <kirtchev@adacore.com>
1237 * sem_ch3.adb (Analyze_Object_Declaration): Do not consider
1238 internally generated expressions when trying to determine whether
1239 a formal parameter of a tagged type subject to Extensions_Visible
1240 False is used to initialize an object.

1242 internally generated expressions when trying to determine whether
1243 a formal parameter of a tagged type subject to Extensions_Visible

1257 deals also with aspects.
1258 (Get_SPARK_Mode_Type): Make function internal again.
1259 * inline.adb, sem_ch7.adb, sem_util.adb: Use new
1260 Get_SPARK_Mode_From_Annotation.

1330 calls inside expression functions. Factor previous code issuing
1331 errors to call Cannot_Inline instead, which does appropriate
1332 processing of message for GNATprove.
1334 2016-04-18 Arnaud Charlet <charlet@adacore.com>
1336 * einfo.ads, sem_ch3.adb, sem_ch8.adb, osint-l.adb, rtsfind.adb,

1415 on the entity of a subprogram declaration that is completed by
1416 an expression function.

1420 * sem_util.adb (Is_Current_Instance): A entity given by a subtype
1421 declaration can appear in an aspect specification for a dynamic
1422 predicate, and a pragma for aspect Predicate_Failure.

1424 occurrences of the subtype to which a dynamic predicate applies,
1425 byt the expression that triggers a predicate check. Needed to

1453 alignment for x86_64.
1454 * init.c: Better fix for guard page reset on x86_64-vx7.
1455 Do not try to retrieve the page that actually raised
1456 the signal as the probing mechanism used on x86_64 do not allow
1457 such retrieval. We thus just test if the guard page is active,
1458 and re-activate it if not.
