   8
   9         * sem_ch6.adb (Analyze_Expression_Function): Code cleanup:

  13         ensures that proper warnings are generated for unused formals
  14         in all cases.

 477         but set to an empty list.
 478         (Needs_Result_Accessibility_Level):
 479         Unconditionally return False. This is a temporary
 480         change, disabling the Extra_Accessibility_Of_Result
 481         mechanism.
 482         (Expand_Simple_Function_Return): Check for
 483         Extra_Accessibility_Of_Result parameter's presence instead of
 484         testing Ada_Version when generating a runtime accessibility
 485         check which makes use of the parameter.

 492         They cannot be propagated ahead of the case statement, because

 507
 508         * einfo.ads (Extra_Accessibility): Update associated comment to use
 509         the term "present" correctly ("present" just means that it is not
 510         an error to query the value of the attribute - it does not imply
 511         that the value must be non-null).

 518         Extra_Accessibility_Of_Result actual parameter even if Ada_Version
 519         < Ada_2012. This can occur if the callee is exported from a Gnat

 544
 545 2011-09-06  Steve Baird  <baird@adacore.com>
 546
 547         * einfo.ads (Extra_Accessibility_Of_Result): New function; in the
 548         (Ada2012) cases described in AI05-0234 where the accessibility
 549         level of a function result is "determined by the point of
 550         call", an implicit parameter representing that accessibility
 551         level is passed in. Extra_Accessibilty_Of_Result yields this
 552         additional formal parameter. Extra_Accessibility_Of_Result
 553         is analogous to the existing Extra_Accessibility
 554         function used in the implementation of access parameters.
 555         (Set_Extra_Accessibility_Of_Result): New procedure; sets
 556         Extra_Accessibility_Of_Result attribute.
 557         * einfo.adb (Extra_Accessibility_Of_Result): New function.
 558         (Set_Extra_Accessibility_Of_Result): New procedure.
 559         (Write_Field19_Name): Display Extra_Accessibilty_Of_Result attribute.
 560         * sem_util.adb (Dynamic_Accessibility_Level): Set Etype of
 561         an accessibility level literal to Natural; introduce a nested
 562         function, Make_Level_Literal, to do this.
 563         * exp_ch6.ads (Needs_Result_Accessibility_Level): New function;
 564         determines whether a given function (or access-to-function
 565         type) needs to have an implicitly-declared accessibility-level
 566         parameter added to its profile.
 567         (Add_Extra_Actual_To_Call): Export an existing procedure which was
 568         previously declared in the body of Exp_Ch6.
 569         * exp_ch6.adb (Add_Extra_Actual_To_Call): Export declaration by moving
 570         it to exp_ch6.ads.
 571         (Has_Unconstrained_Access_Discriminants): New Function; a
 572         predicate on subtype entities which returns True if the given
 573         subtype is unconstrained and has one or more access discriminants.
 574         (Expand_Call): When expanding a call to a function which takes an
 575         Extra_Accessibility_Of_Result parameter, pass in the appropriate
 576         actual parameter value. In the case of a function call which is
 577         used to initialize an allocator, this may not be possible because
 578         the Etype of the allocator may not have been set yet. In this
 579         case, we defer passing in the parameter and handle it later in
 580         Expand_Allocator_Expression.
 581         (Expand_Simple_Function_Return): When returning from a function which
 582         returns an unconstrained subtype having at least one access
 583         discriminant, generate the accessibility check needed to ensure that
 584         the function result will not outlive any objects designated by its
 585         discriminants.
 586         (Needs_Result_Accessibility_Level): New function; see exp_ch6.ads
 587         description.
 588         * exp_ch4.adb (Expand_Allocator_Expression): When a function call
 589         is used to initialize an allocator, we may need to pass in "the
 590         accessibility level determined by the point of call" (AI05-0234)
 591         to the function. Expand_Call, where such actual parameters are
 592         usually generated, is too early in this case because the Etype of
 593         the allocator (which is used in determining the level to be passed
 594         in) may not have been set yet when Expand_Call executes. Instead,
 595         we generate code to pass in the appropriate actual parameter
 596         in Expand_Allocator_Expression.
 597         * sem_ch6.adb (Create_Extra_Formals): Create
 598         the new Extra_Accessibility_Of_Result formal if
 599         Needs_Result_Accessibility_Level returns True. This includes the
 600         introduction of a nested procedure, Check_Against_Result_Level.

 611         s-stposu.Allocate_Any_Controlled to this routine since the check
 612         needs to be protected too.
 613         (Set_Heterogeneous_Finalize_Address): Explain the reason for the
 614         synchronization code.
 615         * s-finmas.ads (Set_Heterogeneous_Finalize_Address): Add comment

 753         restriction No_Dynamic_Attachment is in effect or not should
 754         not influence the default priority associated to a protected
 755         object. With this change, when the restriction is in effect (as
 756         is the case for the Ravenscar profile) the default priority of
 757         a protected object with an interrupt handler is in the range of
 758         interrupt priorities (Default_Interrupt_Priority) as required
 759         by D.3(10).

 909         "postcondition refers only to pre-state" when the expression has not
 910         yet been analyzed, because it causes false alarms. This can happen when
 911         the postcondition contains a quantified expression, because those are
 912         analyzed later. This is a temporary/partial fix.

1170
1171         * s-htable.adb (Set_If_Not_Present): Use renaming
1172         instead of ":=", because the type Key is limited in the generic (even

1187
1188         * checks.adb: (Determine_Range): Add test of OK1 to prevent the early
1189         return done when overflow checks are enabled, since comparisons against
1190         Lor and Hir should not be done when OK1 is False.
1191
1192 2011-09-02  Gary Dismukes  <dismukes@adacore.com>

1194         * exp_ch6.adb (Add_Finalization_Master_Actual_To_Build_In_Place_Call):

1196         call as an extra actual.
1197         (Make_Build_In_Place_Call_In_Object_Declaration): Add variable
1198         Fmaster_Actual and in the case of a BIP call initializing a return
1199         object of an enclosing BIP function set it to a
1200         new reference to the implicit finalization master
1201         formal of the enclosing function. Fmaster_Actual is
1202         then passed to the new formal Master_Exp on the call to

1219
1220         * sem_attr.adb: (Analyze_Attribute, case 'Range): when expanding
1221         X'range (N) into X'First (N) ..  X'Last (N), do not share the
1222         dimension indicator N, if present. Even though it is a static
1223         constant, its source location may be modified when printing
1224         expanded code under -gnatDL, and node sharing will lead to chaos
1225         in Sprint on large files, by generating a sloc value that does
1226         not correspond to any source file.
1227
1228 2011-09-02  Bob Duff  <duff@adacore.com>
1229
1230         * einfo.adb: (Has_Xref_Entry): Do not call
1231         Implementation_Base_Type. Lib.Xref has been
1232         rewritten to avoid the need for it, and it was costly.
1233         * s-htable.ads,s-htable.adb: (Present,Set_If_Not_Present): New
1234         functions in support of efficient xref.

1237         * lib-xref.adb: (Add_Entry,etc): Speed improvement.
1238         (New_Entry): Call Implementation_Base_Type, because Has_Xref_Entry
1239         no longer does. This is the one place where it is needed.
1240
1241 2011-09-02  Johannes Kanig  <kanig@adacore.com>
1242
1243         * g-comlin.adb (Getopt): New optional argument Concatenate to have

1247
1248         * exp_ch4.adb: (Expand_Allocator_Expression): Do not generate
1249         a call to Set_Finalize_Address if there is no allocator available.
1250         * exp_util.adb: (Build_Allocate_Deallocate_Proc): Account for
1251         a case of allocator expansion where the allocator is not expanded but
1252         needs a custom allocate routine. Code reformatting.
1253         (Is_Finalizable_Transient): Remove local variables Has_Rens and
1254         Ren_Obj. Code reformatting.
1255         (Is_Renamed): Renamed to Is_Aliased. Add code to detect aliasing
1256         through the use of 'reference.
1257         * sem_ch4.adb: (Analyze_Allocator): Detect allocators generated
1258         as part of build-in-place expansion. They are intentionally marked as
1259         coming from source, but their parents are not.
1260
1261 2011-09-02  Ed Schonberg  <schonberg@adacore.com>
1262

1264         is the generated subprogram declaration for a child unit body
1265         that acts as spec, use the original body in the with_clause,
1266         to prevent binding errors.

1284
1285         * prj-nmsc.adb: (Find_Sources): When the list of sources is

1287         for an inherited naming exception is not found.
1288

1295
1296         * sem_util.adb (Note_Possible_Modification): If the entity

1348         * sem_ch3.adb: (Build_Derived_Record_Type) Remove the kludgy update of
1349         access discriminant and anonymous access component scopes.
1350         (Inherit_Component): Reuse the itype of an access discriminant
1351         or anonymous access component by copying it in order to set the proper
1352         scope. This is done only when the parent and the derived type
1353         are in different scopes.
1354         (Set_Anonymous_Etype): New routine.
1355
1356 2011-09-01  Robert Dewar  <dewar@adacore.com>

1363         __gnat_cpu_set_free): Create these wrappers around the CPU_ALLOC,
1364         CPU_ALLOC_SIZE and CPU_FREE linux macros.
1365         (__gnat_cpu_zero, __gnat_cpu_set): Use the CPU_ZERO_S and
1366         CPU_SET_S respectively because we are now using dynamically allocated
1367         CPU sets which are more portable across different glibc versions.
1368         * s-osinte-linux.ads (cpu_set_t_ptr, CPU_ALLOC, CPU_ALLOC_SIZE,
1369         CPU_FREE): Add this type and subprograms to be able to create cpu_set_t
1370         masks dynamically according to the number of processors in the target
1371         platform.
1372         (CPU_ZERO, CPU_SET): They are now mapped to the CPU_ZERO_S and CPU_SET_S
1373         respectively, so we need to pass the size of the masks as
1374         parameters.
1375         * s-taprop-linux.adb (Create_Task, Set_Task_Affinity): Use dynamically
1376         created cpu_set_t masks
1377         with the number of processors available in the target platform,
1378         instead of static bit arrays. It enhances portability because
1379         it uses the information from the target platform.
1380         * sem_ch8.adb: (Attribute_Renaming): When checking whether we
1381         are using a restricted run-time library, use the flag
1382         Configurable_Run_Time_Mode instead of Restricted_Profile.

1398         directly the bit array.
1399         * s-osinte-linux.ads (CPU_ZERO, CPU_SET): Import these wrappers around
1400         the linux macros with the same name.
1401         * adaint.h, adaint.c (__gnat_cpu_zero, __gnat_cpu_set): Create these
1402         wrappers around the CPU_ZERO and CPU_SET linux macros.

1457         Test for case where call
1458         initializes an object of a return statement before testing for
1459         a constrained call, to ensure that all such cases get handled
1460         by simply passing on the caller's parameters. Also, in that
1461         case call Needs_BIP_Alloc_Form to determine whether to pass on
1462         the BIP_Alloc_Form parameter of the enclosing function rather
1463         than testing Is_Constrained. Add similar tests for the return
1464         of a BIP call to later processing to ensure consistent handling.

2314         found then skip generating the internal entity. Done to avoid crashing
2315         the frontend.
2316         (Check_Abstract_Overriding): Change text of error of wrong formal of
2317         protected subprogram or entry. Done for consistency to emit exactly the

2367         Build_Finalization_Master by supplying an insertion node and enclosing
2368         scope. In its old version, the call did not generate a finalization
2369         master.
2370         (Expand_Freeze_Record_Type): Add local variable Has_AACC. Add code to
2371         recognize anonymous access-to-controlled components. Rewrite the
2372         machinery which creates finalization masters to service anonymous
2373         access-to-controlled components of a record type. In its current state,
2374         only one heterogeneous master is necessary to handle multiple anonymous
2375         components.
2376         (Freeze_Type): Comment reformatting.
2377         * rtsfind.ads: Add RE_Set_Is_Heterogeneous to tables RE_Id and

2380         associates TSS primitive Finalize_Address with either the master itself
2381         or with the internal hash table depending on the mode of operation of
2382         the master.
2383
2384 2011-08-30  Javier Miranda  <miranda@adacore.com>
2385
2386         * exp_ch3.adb (Make_Eq_If): If the etype of the _parent component is an
2387         interface type then do not generate code to compare this component.
2388         Required since they have no components and their equality operator is
2389         abstract.
2390
2391 2011-08-30  Steve Baird  <baird@adacore.com>
2392
2393         * sem_util.ads (Deepest_Type_Access_Level): New function; for the type
2394         of a saooaaat (i.e, a stand-alone object of an anonymous access type),
2395         returns the (static) accessibility level of the object. Otherwise, the
2396         same as Type_Access_Level.
2397         (Dynamic_Accessibility_Level): New function; given an expression which
2398         could occur as the rhs of an assignment to a saooaaat (i.e., an
2399         expression of an access-to-object type), return the new value for the
2400         saooaaat's associated Extra_Accessibility object.
2401         (Effective_Extra_Accessibility): New function; same as
2402         Einfo.Extra_Accessibility except that object renames are looked through.
2403         * sem_util.adb
2404         (Deepest_Type_Access_Level): New function; see sem_util.ads description.
2405         (Dynamic_Accessibility_Level): New function; see sem_util.ads
2406         description.
2407         (Effective_Extra_Accessibility): New function; see sem_util.ads
2408         description.
2409         * einfo.ads (Is_Local_Anonymous_Access): Update comments.
2410         (Extra_Accessibility): Update comments.
2411         (Init_Object_Size_Align): New procedure; same as Init_Size_Align
2412         except RM_Size field (which is only for types) is unaffected.
2413         * einfo.adb
2414         (Extra_Accessibility): Expand domain to allow objects, not just formals.
2415         (Set_Extra_Accessibility): Expand domain to allow objects, not just
2416         formals.
2417         (Init_Size): Add assertion that we are not trashing the
2418         Extra_Accessibility attribute of an object.
2419         (Init_Size_Align): Add assertion that we are not trashing the
2420         Extra_Accessibility attribute of an object.
2421         (Init_Object_Size_Align): New procedure; see einfo.ads description.
2422         * sem_ch3.adb (Find_Type_Of_Object): Set Is_Local_Anonymous_Access
2423         differently for the type of a (non-library-level) saooaaat depending
2424         whether Ada_Version < Ada_2012. This is the only point where Ada_Version
2425         is queried in this set of changes - everything else (in particular,
2426         setting of the Extra_Accessibility attribute in exp_ch3.adb) is
2427         driven off of the setting of the Is_Local_Anonymous_Access attribute.
2428         The special treatment of library-level saooaaats is an optimization,
2429         not required for correctnesss. This is based on the observation that the
2430         Ada2012 rules (static and dynamic) for saooaaats turn out to be
2431         equivalent to the Ada2005 rules in the case of a library-level saooaaat.
2432         * exp_ch3.adb
2433         (Expand_N_Object_Declaration): If Is_Local_Anonymous_Access is
2434         false for the type of a saooaaat, declare and initialize its
2435         accessibility level object and set the Extra_Accessibility attribute
2436         of the saooaaat to refer to this object.
2437         * checks.adb (Apply_Accessibility_Check): Add Ada 2012 saooaaat support.
2438         * exp_ch4.adb (Expand_N_In): Replace some Extra_Accessibility calls with
2439         calls to Effective_Extra_Accessibility in order to support
2440         renames of saooaaats.
2441         (Expand_N_Type_Conversion): Add new local function,
2442         Has_Extra_Accessibility, and call it when determining whether an
2443         accessibility check is needed.
2444         It returns True iff Present (Effective_Extra_Accessibility (Id)) would
2445         evaluate to True (without raising an exception).
2446         * exp_ch5.adb
2447         (Expand_N_Assignment_Statement): When assigning to an Ada2012
2448         saooaaat, update its associated Extra_Accessibility object (if
2449         it has one). This includes an accessibility check.
2450         * exp_ch6.adb (Add_Call_By_Copy_Code): When parameter copy-back updates
2451         a saooaaat, update its Extra_Accessibility object too (if it
2452         has one).
2453         (Expand_Call): Replace a couple of calls to Type_Access_Level
2454         with calls to Dynamic_Access_Level to handle cases where
2455         passing a literal (any literal) is incorrect.
2456         * sem_attr.adb (Resolve_Attribute): Handle the static accessibility
2457         checks associated with "Saooaat := Some_Object'Access;"; this must
2458         be rejected if Some_Object is declared in a more nested scope
2459         than Saooaat.
2460         * sem_ch5.adb (Analyze_Assignment): Force accessibility checking for an
2461         assignment to a saooaaat even if Is_Local_Anonymous_Access
2462         returns False for its type (indicating a 2012-style saooaaat).
2463         * sem_ch8.adb
2464         (Analyze_Object_Renaming): Replace a call to Init_Size_Align
2465         (which is only appropriate for objects, not types) with a call
2466         of Init_Object_Size_Align in order to avoid trashing the
2467         Extra_Accessibility attribute of a rename (the two attributes
2468         share storage).
2469         * sem_res.adb
2470         (Valid_Conversion) Replace six calls to Type_Access_Level with
2471         calls to Deepest_Type_Access_Level. This is a bit tricky. For an
2472         Ada2012 non-library-level saooaaat, the former returns library level
2473         while the latter returns the (static) accessibility level of the
2474         saooaaat. A type conversion to the anonymous type of a saooaaat
2475         can only occur as part of an assignment to the saooaaat, so we
2476         know that such a conversion must be in a lhs context, so Deepest
2477         yields the result that we need. If such a conversion could occur,
2478         say, as the operand of an equality operator, then this might not
2479         be right. Also add a test so that static accessibilty checks are
2480         performed for converting to a saooaaat's type even if
2481         Is_Local_Anonymous_Access yields False for the type.

2484
2485         * sem_disp.adb (Check_Dispatching_Operation): Complete condition that
2486         controls generation of a warning associated with late declaration of
2487         dispatching functions. Required to avoid generating spurious
2488         warnings.
2489
2490 2011-08-30  Gary Dismukes  <dismukes@adacore.com>
2491
2492         * sem_ch6.adb (Check_Return_Subtype_Indication): Issue error if the
2493         return object has an anonymous access type and the function's type is
2494         a named access type.
2495         * sem_ch8.adb (Analyze_Object_Renaming): Suppress error about renaming
2496         conversions on implicit conversions, since such conversions can occur
2497         for anonymous access cases due to expansion. Issue error for attempt
2498         to rename an anonymous expression as an object of a named access type.
2499         * sem_res.ads (Valid_Conversion): Add defaulted parameter Report_Errs,
2500         to indicate whether this function should report errors on invalid
2501         conversions.
2502         * sem_res.adb (Resolve): For Ada 2012, in the case where the type of
2503         the expression is of an anonymous access type and the expected type is
2504         a named general access type, rewrite the expression as a type
2505         conversion, unless this is an expression of a membership test.
2506         (Valid_Conversion.Error_Msg_N): New procedure that conditions the
2507         calling of Error_Msg_N on new formal Report_Errs.
2508         (Valid_Conversion.Error_Msg_NE): New procedure that conditions the
2509         calling of Error_Msg_NE on new formal Report_Errs.
2510         (Valid_Conversion): Move declaration of this function to the package
2511         spec, to allow calls from membership test processing. For Ada 2012,
2512         enforce legality restrictions on implicit conversions of anonymous
2513         access values to general access types, disallowing such conversions in
2514         cases where the expression has a dynamic accessibility level (access
2515         parameters, stand-alone anonymous access objects, or a component of a
2516         dereference of one of the first two cases).
2517         * sem_type.adb (Covers): For Ada 2012, allow an anonymous access type
2518         in the context of a named general access expected type.
2519         * exp_ch4.adb Add with and use of Exp_Ch2.
2520         (Expand_N_In): Add processing for membership tests applied to
2521         expressions of an anonymous access type. First, Valid_Conversion is
2522         called to check whether the test is statically False, and then the
2523         conversion is expanded to test that the expression's accessibility
2524         level is no deeper than that of the tested type. In the case of
2525         anonymous access-to-tagged types, a tagged membership test is applied
2526         as well.
2527         (Tagged_Membership): Extend to handle access type cases, applying the
2528         test to the designated types.
2529         * exp_ch6.adb (Expand_Call): When creating an extra actual for an
2530         accessibility level, and the actual is a 'Access applied to a current
2531         instance, pass the accessibility level of the type of the current
2532         instance rather than applying Object_Access_Level to the prefix. Add a
2533         ??? comment, since this level isn't quite right either (will eventually
2534         need to pass an implicit level parameter to init procs).

2543         component and the selector is a dispatching operation, check if it is
2544         a prefixed call before rewriting as a parameterless function call.

2592         Bump Choice_Index for each such triple so that a subsequent default
2593         choice is associated with the correct index in the typecode.

2604         processing if we run across a node with no Scope. This can happen if
2605         we're with-ing an library-level instance, and that instance got errors
2606         that caused "instantiation abandoned".
2607         * sem_util.adb (Unit_Declaration_Node): Make it more robust, by raising
2608         an exception instead of using Assert, so it won't go into an infinite

5499         (between unit names and truncated base names without suffixes).

5937
5938         * s-tasren.adb (Task_Do_Or_Queue): Previous code was reading
5939         Acceptor.Terminate_Alternative without locking Acceptor, which causes a
5940         race condition whose symptom is to fail to lock Parent. That, in turn,
5941         causes Parent.Awake_Count to be accessed without locking Parent, which
5942         causes another race condition whose symptom is that Parent.Awake_Count
5943         can be off by 1 (either too high or too low). The solution is to lock
5944         Parent unconditionally, and then lock Acceptor, before reading
5945         Acceptor.Terminate_Alternative.

6553         from Gen_Adainit_Ada.
6554         (Gen_Elab_Externals_C): Likewise, but taken from Gen_Adainit_C.
6555         (Gen_Adafinal_Ada): Remove redundant test.  In the non-main program
6556         case, do not call System.Standard_Library.Adafinal; instead call
6557         finalize_library if needed.
6558         (Gen_Adafinal_C): Likewise.
6559         (Gen_Adainit_Ada): Do not set SSL.Finalize_Library_Objects in the
6560         non-main program case.

6567         (Gen_Main_C): Put back call to Ada_Final and don't finalize library
6568         objects here.
6569         (Gen_Output_File_Ada): Generate pragma Linker_Destructor for Ada_Final

6577
6578         * prj.adb, prj.ads, makeutl.adb, makeutl.ads (Complete_Mains,
6579         Compute_Compilation_Phases): new subprogram.
6580         (Builder_Data, Builder_Project_Tree_Data): new subprogram and type
6581         The number of mains as well as the various compilation phases that
6582         need to be run are now project tree specific, since various
6583         aggregated trees might have different requirements. In particular,
6584         they do not all require bind or link phases.
6585
6586 2011-08-04  Emmanuel Briot  <briot@adacore.com>
6587
6588         * prj.adb, prj.ads, makeutl.adb, makeutl.ads, prj-env.adb
6589         (Project_Tree_Appdata): New type.
6590         It is now possible to associate application-specific data to a project
6591         tree. In particular, this is used in the gprbuild builder to avoid a
6592         number of global tables and htables, especially now that there can be
6593         several project trees loaded at once because of aggregate projects.
6594         (Debug_Name): new procedure.
6595         * projects.texi: Clarify syntax of "**" for Source_Dirs
6596

6598
6599         * prj.ads, makeutl.adb, makeutl.ads (Queue.Insert): now also inserts
6600         the "roots" for a main.
6601         (Fill_From_Project): add support for aggregate projects. Main units
6602         in aggregated projects are now automatically added in the list of
6603         files to build (although this fails later on in gprbuild, because
6604         these files are not using the root proejct tree, so this needs
6605         further cleanup)
6606         * gcc-interface/Make-lang.in: Update dependencies.
6607
6608 2011-08-03  Yannick Moy  <moy@adacore.com>

6622         (Insert_Project_Sources, Insert_withed_Sources_For): moved from the
6623         gprbuild sources.
6624         These packages are more logically placed in the Queue package, since
6625         they manipulate the queue. It is also likely that they can be adapted
6626         for gnatmake, thus sharing more code.
6627         (Finish_Program, Fail_Program): moved from the gprbuild sources, so
6628         that we could move the above.
6629
6630 2011-08-03  Emmanuel Briot  <briot@adacore.com>
6631
6632         * errutil.adb (Finalize): clean up the list of error messages on exit.
6633         Calling this subprogram multiple times will no longer show duplicate
6634         error messages on stderr.
6635
6636 2011-08-03  Emmanuel Briot  <briot@adacore.com>
6637
6638         * g-comlin.adb, g-comlin.ads (Set_Command_Line): ignore the parameter
6639         Getopt_Switches when we have already define a command line
6640         configuration.
6641
6642 2011-08-03  Yannick Moy  <moy@adacore.com>
6643
6644         * sem_ch11.adb (Analyze_Raise_xxx_Error): do not mark such nodes as not
6645         in ALFA. Instead, they are considered as assertions to prove.
6646         * sem_ch4.adb (Analyze_Conditional_Expression): do not always mark such
6647         nodes as not in ALFA. Instead, include conditional expressions in ALFA
6648         if they have no ELSE part, or if they occur in pre- and postconditions,
6649         where the Condition cannot have side-effects in ALFA
6650         (Analyze_Membership_Op): do not mark such nodes as not in ALFA
6651         (Analyze_Type_Conversion): do not always mark such nodes as not in ALFA.
6652         Instead, include type conversion between scalar types in ALFA.
6653         * sem_ch6.adb (Process_Formals): correctly mark a parameter in ALFA
6654         if-and-only-if its type is in ALFA.

6659         New code letter for decisions: G (entry guard)
6660         * par_sco.adb
6661         (Traverse_Subprogram_Body): Rename to...
6662         (Traverse_Subprogram_Or_Task_Body): New subrpogram.
6663         (Traverse_Protected_Body): New subprogram
6664         (Traverse_Declarations_Or_Statements): Add traversal of task bodies,
6665         protected bodies and entry bodies.
6666
6667 2011-08-03  Yannick Moy  <moy@adacore.com>
6668
6669         * einfo.adb, einfo.ads (Is_Postcondition_Proc): new flag for procedure
6670         entities with get/set subprograms, which is set on procedure entities
6671         generated by the compiler for a postcondition.
6672         * sem_ch6.adb (Process_PPCs): set new flag on postcondition procedures
6673         * alfa.adb, alfa.ads (Get_Entity_For_Decl): new function returning the
6674         entity for a declaration
6675         (Get_Unique_Entity_For_Decl): new function returning an entity which
6676         represents a declaration, so that matching spec and body have the same
6677         entity.
6678
6679 2011-08-03  Robert Dewar  <dewar@adacore.com>
6680

6682         a-cforma.adb, a-cforse.ads, a-cforse.adb: Minor reformatting
6683
6684 2011-08-03  Yannick Moy  <moy@adacore.com>
6685
6686         * lib-xref-alfa.adb (Detect_And_Add_ALFA_Scope): make the subprogram
6687         library-level because retriction No_Implicit_Dynamic_Code in the
6688         front-end prevents its definition as a local subprogram
6689         (Traverse_Compilation_Unit): extract new procedure from Add_ALFA_File,
6690         for reuse in other contexts

6699 2011-08-03  Javier Miranda  <miranda@adacore.com>
6700
6701         * sem_prag.adb (Process_Interface_Name): Allow duplicated export names
6702         in Java since they are always enclosed in a namespace that
6703         differentiates them, and overloaded entities are supported by the VM.
6704
6705 2011-08-03  Ed Schonberg  <schonberg@adacore.com>
6706
6707         * checks.adb (Determine_Range): If a computed bound of an operation is
6708         outside the range of the base type of the expression, and overflow
6709         checks are enabled, the result is unknown and cannot be used for any
6710         subsequent constant folding.
6711         * sem_eval.adb (Compile_Time_Compare): if the bounds of one operand are
6712         unknown, so is the result of the comparison.

6725         From_Abort.
6726         * exp_ch7.adb:(Build_Adjust_Or_Finalize_Statements): New local variable

6740         Abort_Id.
6741         (Build_Object_Declarations): Add new formal Abort_Id. Create the
6742         declaration of flag Abort_Id to preserve the original abort status
6743         before finalization code is executed.
6744         (Build_Raise_Statement): Add new formal Abort_Id. Pass Abort_Id to
6745         runtime routine Raise_From_Controlled_Operation.

6774
6775         * exp_ch7.adb (Create_Finalizer): Treat freeze nodes in similar fashion
6776         to packages. This ensures that the finalizer body will not end up
6777         inside the freeze node.
6778         (Process_Declarations): Add code to detect whether a freeze node has a
6779         nested finalization collection.

6799         the tree structure related to discriminant constraints.
6800         Original_Discriminant cannot be used any more for computing the

6804
6805         * sem_disp.adb (Is_Tag_Indeterminate): If the return type of the
6806         function is not visibly tagged, this is not a dispatching call and
6807         therfore is not Tag_Indeterminate, even if the function is marked as
6808         dispatching on result.

6842         is a renaming declaration in the private part of a package, do not emit
6843         a warning that the with_clause could be moved because the renaming may

6857         (Cleanup_Protected_Object, Cleanup_Task): For restricted run-time
6858         libraries (Ravenscar), tasks are non-terminating, and protected objects
6859         and tasks can only appear at library level, so we do not want
6860         finalization of protected objects nor tasks.
6861         * exp_intr.adb: Minor clarification in comment.
6862         bindgen.adb (Gen_Adainit_Ada, Gen_Main_C, Gen_Output_File_Ada,
6863         Gen_Output_File_C): Remove references to finalization of library-level
6864         objects when using restricted run-time libraries.

6871 2011-08-03  Hristian Kirtchev  <kirtchev@adacore.com>
6872
6873         * exp_ch13.adb: Add with and use clause for Targparm;
6874         (Expand_N_Free_Statement): Prevent the generation of a custom
6875         Deallocate on .NET/JVM targets since this requires pools and address
6876         arithmetic.
6877         * exp_ch4.adb (Expand_Allocator_Expression): When compiling for
6878         .NET/JVM targets, attach the newly allocated object to the access
6879         type's finalization collection. Do not generate a call to
6880         Set_Finalize_Address_Ptr on .NET/JVM because this routine does not
6881         exist in the runtime.
6882         (Expand_N_Allocator): When compiling for .NET/JVM targets, do not
6883         create a custom Allocate for object that do not require initialization.
6884         Attach a newly allocated object to the access type's finalization
6885         collection on .NET/JVM.
6886         * exp_ch5.adb (Make_Tag_Ctrl_Assignment): Add special processing for
6887         assignment of controlled types on .NET/JVM. The two hidden pointers
6888         Prev and Next and stored and later restored after the assignment takes
6889         place.
6890         * exp_ch6.adb (Expand_Call): Add local constant Curr_S. Add specialized
6891         kludge for .NET/JVM to recognize a particular piece of code coming from
6892         Heap_Management and change the call to Finalize into Deep_Finalize.
6893         * exp_ch7.adb (Build_Finalization_Collection): Allow the creation of
6894         finalization collections on .NET/JVM only for types derived from
6895         Controlled. Separate the association of storage pools with a collection
6896         and only allow it on non-.NET/JVM targets.
6897         (Make_Attach_Call): New routine.
6898         (Make_Detach_Call): New routine.
6899         (Process_Object_Declarations): Suppress the generation of
6900         build-in-place return object clean up code on .NET/JVM since it uses
6901         pools.
6902         * exp_ch7.ads (Make_Attach_Call): New routine.
6903         (Make_Detach_Call): New routine.
6904         * exp_intr.adb Add with and use clause for Targparm.
6905         (Expand_Unc_Deallocation): Detach a controlled object from a collection
6906         on .NET/JVM targets.
6907         * rtsfind.ads: Add entries RE_Attach, RE_Detach and
6908         RE_Root_Controlled_Ptr to tables RE_Id and RE_Unit_Table.
6909         * snames.ads-tmpl: Add name Name_Prev. Move Name_Prev to the special
6910         names used in finalization.
6911
6912 2011-08-03  Hristian Kirtchev  <kirtchev@adacore.com>
6913
6914         * a-fihema.adb: Add with and use clauses for System.Soft_Links.
6915         (Attach, Detach): Lock the current task when chaining an object onto a
6916         collection.
6917
6918 2011-08-03  Hristian Kirtchev  <kirtchev@adacore.com>
6919
6920         * a-except.adb, a-except-2005.adb (Raise_From_Controlled_Operation):
6921         Rewritten to create the message strings when the exception is not
6922         raised by an abort during finalization.
6923         * a-except.ads, a-except-2005.ads: Add pragma Export for procedure
6924         Raise_From_Controlled_Operation and update its associated comment.
6925         * a-fihema.ads, a-fihema.adb: New GNAT unit.
6926         Ada.Finalization.Heap_Management provides key functionality
6927         associated with controlled objects on the heap, their creation,
6928         finalization and reclamation. Type Finalization_Collection is
6929         effectively a wrapper which sits ontop of a storage pool and performs
6930         all necessary bookkeeping for all the objects it contains. Each
6931         access-to-controlled or access-to-class-wide type receives a collection
6932         as part of its expansion. The compiler generates buffer code and
6933         invokes Allocate / Deallocate to create and destroy allocated
6934         controlled objects.
6935         * a-finali.adb ("="): Removed.
6936         * a-finali.ads ("="): Removed. Controlled types no longer carry hidden
6937         fields Prev and Next.
6938         * ali.adb (Scan_ALI): Add parsing code to process PF / Has_Finalizer.
6939         A library unit with at least one controlled object on the library level
6940         has a special finalizer which is invoked by the binder. To signal this,
6941         ali files carry field PF.
6942         * ali.ads: New field in type Unit_Record called Has_Finalizer. Add
6943         associated comment on field usage.
6944         * a-tags.adb (Get_RC_Offset): Removed.
6945         (Needs_Finalization): New routine.
6946         * a-tags.ads: Update the structure of the GNAT dispatch tables.
6947         Dispatch tables now carry field Needs_Finalization which provides
6948         runtime indication whether a type is controlled or has controlled
6949         components or both. Remove field RC_Offset.
6950         (Get_RC_Offset): Removed along with its associated pragma Export.
6951         Since tagged types with controlled components no longer carry hidden
6952         field _controller, the special mechanism to retrieve its location is no
6953         longer needed.
6954         (Needs_Finalization): New routine.
6955         * atree.ads, atree.adb (Elist24): New routine.
6956         (Set_Elist24): New routine.
6957         * atree.h: Add a define clause for Elist24.
6958         * bindgen.adb New library-level variable Lib_Final_Built.
6959         (Gen_Adafinal_Ada): Reimplemented. Depending on the restrictions or the
6960         presence of a VM target, the routine generates calls to the proper
6961         library finalization routine.
6962         (Gen_Adainit_Ada): Import Finalize_Library_Objects only on non-VM
6963         targets. Set the correct library finalization routine depending on
6964         whether the library has controlled objects or this is a VM compilation.
6965         (Gen_Finalize_Library_Ada): New routine. This procedure generates calls
6966         to library-level finalizers of compiled units in reverse order of
6967         elaboration. It also produces exception management code and reraises a
6968         potential exception after all units have been finalized.
6969         (Gen_Finalize_Library_C): New routine. This procedure generates calls to
6970         library-level finalizers of compiled units in reverse order of
6971         elaboration.
6972         (Gen_Finalize_Library_Defs_C): New routine. This procedure generates the
6973         definitions of all library-level finalizers available to the compilation
6974         (Gen_Main_Ada): Directly call Adafinal which now contails all target
6975         dependent code.
6976         (Gen_Main_C): Add new local constant Needs_Library_Finalization. Call
6977         System.Standard_Library.Adafinal directly. If the library needs
6978         finalization actions, create the sequence of finalization calls.
6979         (Gen_Output_File_Ada): Alphabetize local variables and constants.
6980         Generate a with clause for System.Soft_Links when compiling for a VM.
6981         Remove the code which imports System.Standard_Library.Adafinal as
6982         Do_Finalize. Generate the library finalization routine.
6983         (Gen_Output_File_C): Add new local constant Needs_Library_Finalization.
6984         If the library needs finalization actions, create all the definitions
6985         of library- level finalizers.
6986         (Has_Finalizer): New routine. Determines whether at least one compiled
6987         unit has a library-level finalizer.
6988         Add type Qualification_Mode.
6989         (Set_Unit_Name): Add a formal which controls the replacement of a dot.
6990         * einfo.adb: New usage of field 15 as Return_Flag.
6991         Remove Finalization_Chain_Entity from the usages of field 19.
6992         Remove Associated_Final_Chain from the usages of field 23.
6993         New usage of field 23 as Associated_Collection.

7797         a unit name as index and therefore should be case insensitive.
7798         Minor refactoring (reduce length of variable names).

7915         low bound is not known at compile time but they have no others choice.

7935         as a condition for the delayed call to Derived_Subprograms done for the
7936         case of the rewriting of a derived type that constrains the
7937         discriminants of its parent type.
7938         Avoids redundant subprogram derivations for private subtype derivations.

7971         (Scan_ALI): do not issue a fatal error if parsing known lines after Xref
7972         section (does not happen in compiler, only if code directly calls
7973         Scan_ALI).
7974         * get_alfa.adb, get_alfa.ads: New files.
7975         * lib-writ.adb, lib-writ.ads (Write_ALI): output ALFA information if

7980         Push ALFA treatments in separated local package.
7981         (Enclosing_Subpragram_Or_Package): treat specially subprogram

8013         type, always use 1 as the lower bound or string, even if lower bound of
8014         context is not static, to handle properly null strings in a non-static
8015         context.
8016
8017 2011-08-03  Bob Duff  <duff@adacore.com>
8018
8019         * sem_prag.adb (Resolve_Aggregate): An array aggregate with 'others' is
8020         always legal on the right-hand side of an assignment statement; there
8021         is always an applicable index constraint in this case. Therefore, the
8022         check for Pkind = N_Assignment_Statement is now unconditional -- it
8023         doesn't depend on whether Is_Constrained (Typ).

8035

8043
8044 2011-08-03  Thomas Quinot  <quinot@adacore.com>
8045
8046         * exp_ch5.adb (Expand_N_Assignment_Statement): Do not force inlining of
8047         tagged assignment when discriminant checks are suppressed. This is
8048         useless and extremely costly in terms of static stack usage.
8049
8050 2011-08-03  Bob Duff  <duff@adacore.com>
8051
8052         * sem_prag.adb (Get_Base_Subprogram): Do not follow Alias for instances
8053         of generics, because this leads to the wrong entity in the wrong scope,
8054         causing (e.g.) pragma Export_Procedure to get an error if the entity is
8055         an instance.
8056         (Process_Interface_Name): Follow Alias for instances of generics, to
8057         correct for the above change.
8058
8059 2011-08-03  Ed Schonberg  <schonberg@adacore.com>
8060
8061         * exp_ch4.adb (Expand_N_Selected_Component): If the discriminant value
8062         is an integer literal it is always safe to replace the reference. In
8063         addition, if the reference appears in the generated code for an object
8064         declaration it is necessary to copy because otherwise the reference
8065         might be to the uninitilized value of the discriminant of the object
8066         itself.

8072         anywhere in the path.
8073

8075
8076         * tree_io.ads (ASIS_Version_Number): Update because of the changes in

8081

8087

8091

8093
8094         * sem_res.adb (Set_String_Literal_Subtype): if the lower bound of the

8124
8125         * sem_ch3.adb (Analyze_Object_Declaration): if a constant object of an
8126         unconstrained type with discriminants is initialized with an aggregate,
8127         use the constrained subtype of the aggregate as the type of the object,
8128         because it is immutable, and this allows the back-end to generate no
8129         code for the object declaration.

8142         * exp_ch3.adb
8143         (Expand_N_Object_Declaration): Add missing support to handle

8667
8668         * sem_ch5.adb (Analyze_Loop_Statement):  If the iteration scheme is an
8669         Ada2012 iterator, the loop will be rewritten during expansion into a
8670         while loop with a cursor and an element declaration. Do not analyze the
8671         body in this case, because if the container is for indefinite types the
8672         actual subtype of the elements will only be determined when the cursor
8673         declaration is analyzed.

8681
8682         * sem_ch3.adb (Check_Ops_From_Incomplete_Type): Remove call to
8683         Prepend_Element, since this can result in the operation getting the
8684         wrong slot in the full type's dispatch table if the full type has
8685         inherited operations. The incomplete type's operation will get added
8686         to the proper position in the full type's primitives
8687         list later in Sem_Disp.Check_Operation_From_Incomplete_Type.
8688         (Process_Incomplete_Dependents): Add Is_Primitive test when checking for
8689         dispatching operations, since there are cases where nonprimitive
8690         subprograms can get added to the list of incomplete dependents (such
8691         as subprograms in nested packages).
8692         * sem_ch6.adb (Process_Formals): First, remove test for being in a
8693         private part when determining whether to add a primitive with a
8694         parameter of a tagged incomplete type to the Private_Dependents list.
8695         Such primitives can also occur in the visible part, and should not have
8696         been excluded from being private dependents.
8697         * sem_ch7.adb (Uninstall_Declarations): When checking the rule of
8698         RM05-3.10.1(9.3/2), test that a subprogram in the Private_Dependents
8699         list of a Taft-amendment incomplete type is a primitive before issuing
8700         an error that the full type must appear in the same unit. There are
8701         cases where nonprimitives can be in the list (such as subprograms in
8702         nested packages).
8703         * sem_disp.adb (Derives_From): Use correct condition for checking that
8704         a formal's type is derived from the type of the corresponding formal in
8705         the parent subprogram (the condition was completely wrong). Add
8706         checking that was missing for controlling result types being derived
8707         from the result type of the parent operation.

8718         before accessing operands.
8719         * sem_util.adb (Is_SPARK_Initialization_Expr): follow original nodes to
8720         decide whether an initialization expression respects SPARK rules, as
8721         the plain node is the expanded one. This allows for more valid warnings
8722         to be issued.
8723         * gnat_rm.texi: Minor update.

8748         association.
8749         * errout.adb (First_Node): Exclude nodes with no Sloc, and always use

8754         * exp_ch5.adb (Expand_Iterator_Loop): Code cleanup and refactoring.
8755         When a container is provided via a function call, generate a renaming
8756         of the function result. This avoids the creation of a transient scope
8757         and the premature finalization of the container.
8758         * exp_ch7.adb (Is_Container_Cursor): Removed.
8759         (Wrap_Transient_Declaration): Remove the supression of the finalization

8771         Array_Type_Declaration): postpone the test for the type being a subtype

8773         expanded-name are discriminated.
8774         (Make_Index, Process_Range_Expr_In_Decl): add a parameter In_Iter_Schm
8775         to distinguish the case of an iteration scheme, so that an error is
8776         issed on a non-static range in SPARK except in an iteration scheme.
8777         * sem_ch5.adb (Analyze_Iteration_Scheme): call Make_Index with

8789         (Check_Later_Vs_Basic_Declarations): add a new function
8790         Is_Later_Declarative_Item to decice which declarations are allowed as
8791         later items, in the two different modes Ada 83 and SPARK. In the SPARK
8792         mode, add that renamings are considered as later items.

8794         (Enter_Name): correct the rule for homonyms in SPARK

8818         * opt.ads (SPARK_Mode): update comment, SPARK_Mode only set through
8819         command line now.
8820         * par-ch3.adb (P_Delta_Constraint): remove check in SPARK mode that the
8821         expression is a simple expression. This check cannot be performed in
8822         the semantics, so just drop it.
8823         (P_Index_Or_Discriminant_Constraint): move check that the index or
8824         discriminant is a subtype mark to Analyze_Subtype_Declaration in the
8825         semantics. Other cases were previously checked in the semantics.
8826         * par-ch4.adb (P_Name): move checks that a selector name is not
8827         character literal or an operator symbol to Find_Selected_Component in
8828         the semantics

8830         declarations are not placed after later declarations in a separate
8831         procedure in Sem_Util (possibly not the best choice?), to be used both

8833         SPARK mode.
8834         * par-endh.adb (Check_End): move check that end label is not missing
8835         to Process_End_Label in the semantics
8836         * par-prag.adb (Process_Restrictions_Or_Restriction_Warnings): remove
8837         the special case for SPARK restriction

8840         parameter Force to issue the error message even on internal node (used
8841         for generated end label). Call Check_Restriction to check when an error
8842         must be issued. In SPARK mode, issue an error message even if the
8843         restriction is not set.

8850         declarations are not placed after later declarations, by calling
8851         Check_Later_Vs_Basic_Declarations
8852         (Analyze_Subtype_Declaration): move here the check that an index or
8853         discriminant constraint must be a subtype mark. Change the check that
8854         a subtype of String must start at one so that it works on subtype marks.
8855         * sem_ch4.adb (Analyze_Call): move here the check that a named
8856         association cannot follow a positional one in a call
8857         * sem_ch5.adb (Check_Unreachable_Code): call Check_Formal_Restriction
8858         instead of issuing an error message directly
8859         * sem_ch8.adb (Find_Selected_Component): move here the check that a
8860         selector name is not a character literal or an operator symbol. Move
8861         here the check that the prefix of an expanded name cannot be a
8862         subprogram or a loop statement.
8863         * sem_util.adb, sem_util.ads (Check_Later_Vs_Basic_Declarations): new
8864         procedure called from parsing and semantics to check that basic
8865         declarations are not placed after later declarations

9155
9156         * exp_ch4.adb (Expand_N_Quantified_Expression): Force reanalysis and
9157         expansion of the condition. Required since the previous analysis was
9158         done with expansion disabled (see Resolve_Quantified_Expression) and
9159         hence checks were not inserted and record comparisons have not been
9160         expanded.

9172
9173         * sem_ch12.adb (Analyze_Package_Instantiation,
9174         Analyze_Subprogram_Instantiation): Turn off style checking while
9175         analyzing an instance. Whatever style checks that apply to the generic
9176         unit should apply, so it makes no sense to apply them in an instance.
9177         This was causing trouble when compiling an instance of a runtime
9178         unit that violates the -gnatyO switch.
9179         * stylesw.adb (Set_Style_Check_Options): "when 'O' =>" was missing from
9180         one of the two case statements, causing spurious errors.

9299         * sem_res.adb (Resolve_Actuals): in formal mode, check that actual
9300         parameters matching formals of tagged types are objects (or ancestor
9301         type conversions of objects), not general expressions. Issue an error
9302         on view conversions that are not involving ancestor conversion of an
9303         extended type.

9330         routine Force_Evaluation which centralizes this work in the frontend.

9432         no action. Done to incorporate documentation on new cases uncovered

9435         * sem_res.adb (Resolve_Slice): Minor code cleanup replacling two calls
9436         to routine Remove_Side_Effects by calls to Force_Evaluation since they

11860         * sem_ch5.adb (Analyze_Loop_Statement):  If the iteration scheme is an
11861         Ada2012 iterator, the loop will be rewritten during expansion into a
11862         while loop with a cursor and an element declaration. Do not analyze the
11863         body in this case, because if the container is for indefinite types the
11864         actual subtype of the elements will only be determined when the cursor
11865         declaration is analyzed.

11873
11874         * sem_ch3.adb (Check_Ops_From_Incomplete_Type): Remove call to
11875         Prepend_Element, since this can result in the operation getting the
11876         wrong slot in the full type's dispatch table if the full type has
11877         inherited operations. The incomplete type's operation will get added
11878         to the proper position in the full type's primitives
11879         list later in Sem_Disp.Check_Operation_From_Incomplete_Type.
11880         (Process_Incomplete_Dependents): Add Is_Primitive test when checking for
11881         dispatching operations, since there are cases where nonprimitive
11882         subprograms can get added to the list of incomplete dependents (such
11883         as subprograms in nested packages).
11884         * sem_ch6.adb (Process_Formals): First, remove test for being in a
11885         private part when determining whether to add a primitive with a
11886         parameter of a tagged incomplete type to the Private_Dependents list.
11887         Such primitives can also occur in the visible part, and should not have
11888         been excluded from being private dependents.
11889         * sem_ch7.adb (Uninstall_Declarations): When checking the rule of
11890         RM05-3.10.1(9.3/2), test that a subprogram in the Private_Dependents
11891         list of a Taft-amendment incomplete type is a primitive before issuing
11892         an error that the full type must appear in the same unit. There are
11893         cases where nonprimitives can be in the list (such as subprograms in
11894         nested packages).
11895         * sem_disp.adb (Derives_From): Use correct condition for checking that
11896         a formal's type is derived from the type of the corresponding formal in
11897         the parent subprogram (the condition was completely wrong). Add
11898         checking that was missing for controlling result types being derived
11899         from the result type of the parent operation.

11910         before accessing operands.
11911         * sem_util.adb (Is_SPARK_Initialization_Expr): follow original nodes to
11912         decide whether an initialization expression respects SPARK rules, as
11913         the plain node is the expanded one. This allows for more valid warnings
11914         to be issued.
11915         * gnat_rm.texi: Minor update.

11940         association.
11941         * errout.adb (First_Node): Exclude nodes with no Sloc, and always use

11945
11946         * exp_ch5.adb (Expand_Iterator_Loop): Code cleanup and refactoring.
11947         When a container is provided via a function call, generate a renaming
11948         of the function result. This avoids the creation of a transient scope
11949         and the premature finalization of the container.
11950         * exp_ch7.adb (Is_Container_Cursor): Removed.
11951         (Wrap_Transient_Declaration): Remove the supression of the finalization
11952         of the list controller when the declaration denotes a container cursor,
11953         it is not needed.

11959         * sem_aggr.adb
11960         (Resolve_Array_Aggregate): refine the check for a static expression, to

11962         * sem_ch3.adb, sem_ch3.ads (Analyze_Component_Declaration,
11963         Array_Type_Declaration): postpone the test for the type being a subtype
11964         mark after the type has been resolved, so that component-selection and
11965         expanded-name are discriminated.
11966         (Make_Index, Process_Range_Expr_In_Decl): add a parameter In_Iter_Schm
11967         to distinguish the case of an iteration scheme, so that an error is
11968         issed on a non-static range in SPARK except in an iteration scheme.
11969         * sem_ch5.adb (Analyze_Iteration_Scheme): call Make_Index with
11970         In_Iter_Schm = True.

11974         (Find_Selected_Component): refine the check for prefixing of operators
11975         so that they are allowed in renaming. Move the checks for restrictions
11976         on selector name after analysis discriminated between
11977         component-selection and expanded-name.
11978         * sem_res.adb (Resolve_Op_Concat_Arg): do not issue a warning on
11979         concatenation argument of string type if it is static.
11980         * sem_util.adb, sem_util.ads
11981         (Check_Later_Vs_Basic_Declarations): add a new function
11982         Is_Later_Declarative_Item to decice which declarations are allowed as
11983         later items, in the two different modes Ada 83 and SPARK. In the SPARK
11984         mode, add that renamings are considered as later items.
11985         (Enclosing_Package): new function to return the enclosing package
11986         (Enter_Name): correct the rule for homonyms in SPARK

12012         * par-ch3.adb (P_Delta_Constraint): remove check in SPARK mode that the
12013         expression is a simple expression. This check cannot be performed in
12014         the semantics, so just drop it.
12015         (P_Index_Or_Discriminant_Constraint): move check that the index or
12016         discriminant is a subtype mark to Analyze_Subtype_Declaration in the
12017         semantics. Other cases were previously checked in the semantics.
12018         * par-ch4.adb (P_Name): move checks that a selector name is not
12019         character literal or an operator symbol to Find_Selected_Component in
12020         the semantics
12021         * par-ch5.adb (Parse_Decls_Begin_End): move check that basic
12022         declarations are not placed after later declarations in a separate
12023         procedure in Sem_Util (possibly not the best choice?), to be used both
12024         during parsing, for Ada 83 mode, and during semantic analysis, for
12025         SPARK mode.
12026         * par-endh.adb (Check_End): move check that end label is not missing
12027         to Process_End_Label in the semantics

12031         * restrict.adb, restrict.ads (Check_Formal_Restriction): add a
12032         parameter Force to issue the error message even on internal node (used
12033         for generated end label). Call Check_Restriction to check when an error
12034         must be issued. In SPARK mode, issue an error message even if the
12035         restriction is not set.
12036         (Check_Restriction): new procedure with an additional out parameter to
12037         inform the caller that a message has been issued
12038         * sem_aggr.adb: Minor modification of message
12039         * sem_attr.adb (Analyze_Attribute): call Check_Formal_Restriction
12040         instead of issuing an error message directly
12041         * sem_ch3.adb (Analyze_Declarations): move here the check that basic
12042         declarations are not placed after later declarations, by calling
12043         Check_Later_Vs_Basic_Declarations
12044         (Analyze_Subtype_Declaration): move here the check that an index or
