   6
   7         * checks.adb (Apply_Float_Conversion_Check): correct a typo where Lo_OK
   8         was used instead of Hi_OK, which could cause a read of an uninitialized
   9         value later on. Detected while working on the new warning.
  10         * exp_ch9.adb (Expand_N_Entry_Declaration): remove useless assignment

  30         (Gen_Output_File_Ada): If CodePeer_Mode is set, generate a with of the
  31         user-defined main program in the context clause of the package body.

  48
  49         * prj-env.adb (Create_Config_Pragmas_File): fix handling of multi-unit
  50         source files with non-standard naming schemes, in imported projects
  51
  52 2011-08-04  Emmanuel Briot  <briot@adacore.com>
  53
  54         * makeutl.adb (Complete_Mains): when a multi-unit source file is
  55         specified on the gprbuild command line, we need to compile all units
  56         within that file, not just the first one we find
  57         Fix error message for mains that are not found.
  58
  59 2011-08-04  Thomas Quinot  <quinot@adacore.com>
  60
  61         * sem_ch6.adb: Update comment.
  62         * sem_ch12.adb: Minor reformatting.
  63
  64 2011-08-04  Bob Duff  <duff@adacore.com>
  65
  66         * s-tasren.adb (Task_Do_Or_Queue): Previous code was reading
  67         Acceptor.Terminate_Alternative without locking Acceptor, which causes a
  68         race condition whose symptom is to fail to lock Parent. That, in turn,
  69         causes Parent.Awake_Count to be accessed without locking Parent, which
  70         causes another race condition whose symptom is that Parent.Awake_Count
  71         can be off by 1 (either too high or too low). The solution is to lock
  72         Parent unconditionally, and then lock Acceptor, before reading
  73         Acceptor.Terminate_Alternative.
  74
  75 2011-08-04  Arnaud Charlet  <charlet@adacore.com>

  84
  85 2011-08-04  Gary Dismukes  <dismukes@adacore.com>
  86

 111         This flag of N_Pragma nodes is not used, remove it as well as all of
 112         the associated circuitry.
 113
 114 2011-08-04  Javier Miranda  <miranda@adacore.com>
 115
 116         * exp_disp.adb (Make_DT): Switch -gnatdQ disables the generation of the
 117         runtime check on duplicated externa tags

 136         * einfo.ads: Rename node field Return_Flag to
 137         Return_Flag_Or_Transient_Decl. Update the associated comment and all
 138         occurrences in entities.

 252         function return contains a controlled [extension] aggregate and the
 253         return statement is not part of a handled sequence of statements, wrap
 254         the return in a block. This ensures that all controlled temporaries
 255         generated during aggregate resolution will be picked up by the
 256         finalization machinery.

 274
 275         * par-ch13.adb (Aspect_Specifications_Present): recognize
 276         "with Identifier'Class =>" as an aspect, so that a meaningful warning
 277         is issued in Strict mode.
 278         * par.adb: Fix typos in comments.
 279
 280 2011-08-04  Yannick Moy  <moy@adacore.com>

 294         * prj.adb (Find_Sources.Look_For_Sources): If the source has been
 295         excluded, continue looking. This excluded source will only be returned
 296         if there is no other source with the same base name that is not locally
 297         removed.
 298
 299 2011-08-04  Ed Schonberg  <schonberg@adacore.com>
 300
 301         * sem_res.adb (Resolve_Intrinsic_Operator): if the result type is
 302         private and one of the operands is a real literal, use a qualified
 303         expression rather than a conversion which is not meaningful to the
 304         back-end.

 313
 314         * s-flocon.adb, s-flocon.ads: Add a body for s-flocon.ads
 315         This will allow to have an Ada implementation for the subprogram.
 316

 318
 319         * sem_ch3.adb (Analyze_Full_Type_Declaration): If the declaration is a
 320         completion and aspects are present, apply them to the entity for the
 321         type which is currently the partial view, but which is the one that
 322         will be frozen.
 323         * sem_ch13.adb (Analyze_Aspect_Specifications): if the predicate
 324         applies to a partial view, indicate that the full view has predicates
 325         and delayed aspects.
 326         (Replace_Type_Reference): Handle properly predicates that apply to the
 327         full view of a private completion.

 336         issue warning and activate Implicit_Packing.
 337         (Freeze_Entity): Likewise.  Do not issue a warning for alias/atomic
 338         if the Esize is not known.
 339         * sem_ch13.adb (Analyze_Attribute_Definition_Clause) <Size>: Set Esize
 340         for elementary types only.
 341         (Analyze_Record_Representation_Clause): Look at the RM size instead
 342         of the Esize to issue errors.
 343         * gcc-interface/decl.c (gnat_to_gnu_entity): Do not set Esize if it
 344         is not known.
 345         <E_Record_Type>: Look at the RM size instead of the Esize.  Remove
 346         obsolete block.
 347         Look at the RM size instead of the Esize for types if the latter is
 348         not known.
 349         (gnat_to_gnu_field): Use Known_Esize instead of Known_Static_Esize.

 352
 353         * sem_type.adb: proper handling of equality not involving anonymous

 357
 358         * exp_ch7.adb (Create_Finalizer): Remove local variables Spec_Nod and
 359         Vis_Decls. When creating a library-level finalizer for a package spec,
 360         both the declaration and body of the finalizer are inserted either in
 361         the visible or private declarations of the package spec.
 362
 363 2011-08-04  Javier Miranda  <miranda@adacore.com>
 364
 365         * sem_ch3.adb (Derive_Subprograms): Complete assertion to request the

 708         (Builder_Data, Builder_Project_Tree_Data): new subprogram and type
 709         The number of mains as well as the various compilation phases that
 710         need to be run are now project tree specific, since various
 711         aggregated trees might have different requirements. In particular,
 712         they do not all require bind or link phases.
 713
 714 2011-08-04  Emmanuel Briot  <briot@adacore.com>
 715
 716         * prj.adb, prj.ads, makeutl.adb, makeutl.ads, prj-env.adb
 717         (Project_Tree_Appdata): New type.
 718         It is now possible to associate application-specific data to a project
 719         tree. In particular, this is used in the gprbuild builder to avoid a
 720         number of global tables and htables, especially now that there can be
 721         several project trees loaded at once because of aggregate projects.
 722         (Debug_Name): new procedure.
 723         * projects.texi: Clarify syntax of "**" for Source_Dirs
 724
 725 2011-08-03  Emmanuel Briot  <briot@adacore.com>
 726
 727         * prj.ads, makeutl.adb, makeutl.ads (Queue.Insert): now also inserts
 728         the "roots" for a main.
 729         (Fill_From_Project): add support for aggregate projects. Main units
 730         in aggregated projects are now automatically added in the list of
 731         files to build (although this fails later on in gprbuild, because
 732         these files are not using the root proejct tree, so this needs
 733         further cleanup)
 734         * gcc-interface/Make-lang.in: Update dependencies.
 735
 736 2011-08-03  Yannick Moy  <moy@adacore.com>

 750         (Insert_Project_Sources, Insert_withed_Sources_For): moved from the
 751         gprbuild sources.
 752         These packages are more logically placed in the Queue package, since
 753         they manipulate the queue. It is also likely that they can be adapted
 754         for gnatmake, thus sharing more code.
 755         (Finish_Program, Fail_Program): moved from the gprbuild sources, so
 756         that we could move the above.
 757
 758 2011-08-03  Emmanuel Briot  <briot@adacore.com>
 759
 760         * errutil.adb (Finalize): clean up the list of error messages on exit.

 762         error messages on stderr.
 763
 764 2011-08-03  Emmanuel Briot  <briot@adacore.com>

 771
 772         * sem_ch11.adb (Analyze_Raise_xxx_Error): do not mark such nodes as not
 773         in ALFA. Instead, they are considered as assertions to prove.
 774         * sem_ch4.adb (Analyze_Conditional_Expression): do not always mark such
 775         nodes as not in ALFA. Instead, include conditional expressions in ALFA
 776         if they have no ELSE part, or if they occur in pre- and postconditions,
 777         where the Condition cannot have side-effects in ALFA
 778         (Analyze_Membership_Op): do not mark such nodes as not in ALFA
 779         (Analyze_Type_Conversion): do not always mark such nodes as not in ALFA.
 780         Instead, include type conversion between scalar types in ALFA.
 781         * sem_ch6.adb (Process_Formals): correctly mark a parameter in ALFA
 782         if-and-only-if its type is in ALFA.

 803         (Get_Unique_Entity_For_Decl): new function returning an entity which
 804         represents a declaration, so that matching spec and body have the same
 805         entity.
 806

 811
 812 2011-08-03  Yannick Moy  <moy@adacore.com>
 813
 814         * lib-xref-alfa.adb (Detect_And_Add_ALFA_Scope): make the subprogram
 815         library-level because retriction No_Implicit_Dynamic_Code in the
 816         front-end prevents its definition as a local subprogram
 817         (Traverse_Compilation_Unit): extract new procedure from Add_ALFA_File,
 818         for reuse in other contexts
 819         (Traverse_Declarations_Or_Statements,
 820         Traverse_Handled_Statement_Sequence, Traverse_Package_Body,

 828
 829         * sem_prag.adb (Process_Interface_Name): Allow duplicated export names
 830         in Java since they are always enclosed in a namespace that
 831         differentiates them, and overloaded entities are supported by the VM.
 832
 833 2011-08-03  Ed Schonberg  <schonberg@adacore.com>
 834
 835         * checks.adb (Determine_Range): If a computed bound of an operation is
 836         outside the range of the base type of the expression, and overflow
 837         checks are enabled, the result is unknown and cannot be used for any
 838         subsequent constant folding.
 839         * sem_eval.adb (Compile_Time_Compare): if the bounds of one operand are
 840         unknown, so is the result of the comparison.

 843
 844         * a-except-2005.adb (Raise_From_Controlled_Operation): Add new formal

 870         declaration of flag Abort_Id to preserve the original abort status
 871         before finalization code is executed.
 872         (Build_Raise_Statement): Add new formal Abort_Id. Pass Abort_Id to
 873         runtime routine Raise_From_Controlled_Operation.

 877         (Make_Handler_For_Ctrl_Operation): Add an actual for From_Abort.
 878         (Process_Transient_Objects): New local variable Abort_Id. Remove the
 879         clunky code to create all flags and objects related to

 902
 903         * exp_ch7.adb (Create_Finalizer): Treat freeze nodes in similar fashion

 905         inside the freeze node.
 906         (Process_Declarations): Add code to detect whether a freeze node has a
 907         nested finalization collection.

 934         function is not visibly tagged, this is not a dispatching call and
 935         therfore is not Tag_Indeterminate, even if the function is marked as
 936         dispatching on result.

 986         libraries (Ravenscar), tasks are non-terminating, and protected objects
 987         and tasks can only appear at library level, so we do not want
 988         finalization of protected objects nor tasks.
 989         * exp_intr.adb: Minor clarification in comment.
 990         bindgen.adb (Gen_Adainit_Ada, Gen_Main_C, Gen_Output_File_Ada,

1000
1001         * exp_ch13.adb: Add with and use clause for Targparm;
1002         (Expand_N_Free_Statement): Prevent the generation of a custom

1004         arithmetic.
1005         * exp_ch4.adb (Expand_Allocator_Expression): When compiling for
1006         .NET/JVM targets, attach the newly allocated object to the access
1007         type's finalization collection. Do not generate a call to

1009         exist in the runtime.
1010         (Expand_N_Allocator): When compiling for .NET/JVM targets, do not
1011         create a custom Allocate for object that do not require initialization.

1018         * exp_ch6.adb (Expand_Call): Add local constant Curr_S. Add specialized
1019         kludge for .NET/JVM to recognize a particular piece of code coming from

1021         * exp_ch7.adb (Build_Finalization_Collection): Allow the creation of
1022         finalization collections on .NET/JVM only for types derived from
1023         Controlled. Separate the association of storage pools with a collection
1024         and only allow it on non-.NET/JVM targets.

1026         (Make_Detach_Call): New routine.
1027         (Process_Object_Declarations): Suppress the generation of

1047
1048         * a-except.adb, a-except-2005.adb (Raise_From_Controlled_Operation):
1049         Rewritten to create the message strings when the exception is not
1050         raised by an abort during finalization.
1051         * a-except.ads, a-except-2005.ads: Add pragma Export for procedure
1052         Raise_From_Controlled_Operation and update its associated comment.
1053         * a-fihema.ads, a-fihema.adb: New GNAT unit.
1054         Ada.Finalization.Heap_Management provides key functionality
1055         associated with controlled objects on the heap, their creation,
1056         finalization and reclamation. Type Finalization_Collection is
1057         effectively a wrapper which sits ontop of a storage pool and performs
1058         all necessary bookkeeping for all the objects it contains. Each
1059         access-to-controlled or access-to-class-wide type receives a collection
1060         as part of its expansion. The compiler generates buffer code and
1061         invokes Allocate / Deallocate to create and destroy allocated
1062         controlled objects.
1063         * a-finali.adb ("="): Removed.
1064         * a-finali.ads ("="): Removed. Controlled types no longer carry hidden
1065         fields Prev and Next.
1066         * ali.adb (Scan_ALI): Add parsing code to process PF / Has_Finalizer.
1067         A library unit with at least one controlled object on the library level
1068         has a special finalizer which is invoked by the binder. To signal this,
1069         ali files carry field PF.
1070         * ali.ads: New field in type Unit_Record called Has_Finalizer. Add
1071         associated comment on field usage.
1072         * a-tags.adb (Get_RC_Offset): Removed.
1073         (Needs_Finalization): New routine.
1074         * a-tags.ads: Update the structure of the GNAT dispatch tables.
1075         Dispatch tables now carry field Needs_Finalization which provides
1076         runtime indication whether a type is controlled or has controlled
1077         components or both. Remove field RC_Offset.
1078         (Get_RC_Offset): Removed along with its associated pragma Export.
1079         Since tagged types with controlled components no longer carry hidden
1080         field _controller, the special mechanism to retrieve its location is no
1081         longer needed.
1082         (Needs_Finalization): New routine.
1083         * atree.ads, atree.adb (Elist24): New routine.
1084         (Set_Elist24): New routine.
1085         * atree.h: Add a define clause for Elist24.
1086         * bindgen.adb New library-level variable Lib_Final_Built.
1087         (Gen_Adafinal_Ada): Reimplemented. Depending on the restrictions or the
1088         presence of a VM target, the routine generates calls to the proper
1089         library finalization routine.
1090         (Gen_Adainit_Ada): Import Finalize_Library_Objects only on non-VM
1091         targets. Set the correct library finalization routine depending on
1092         whether the library has controlled objects or this is a VM compilation.
1093         (Gen_Finalize_Library_Ada): New routine. This procedure generates calls
1094         to library-level finalizers of compiled units in reverse order of
1095         elaboration. It also produces exception management code and reraises a
1096         potential exception after all units have been finalized.
1097         (Gen_Finalize_Library_C): New routine. This procedure generates calls to
1098         library-level finalizers of compiled units in reverse order of
1099         elaboration.
1100         (Gen_Finalize_Library_Defs_C): New routine. This procedure generates the
1101         definitions of all library-level finalizers available to the compilation
1102         (Gen_Main_Ada): Directly call Adafinal which now contails all target
1103         dependent code.
1104         (Gen_Main_C): Add new local constant Needs_Library_Finalization. Call
1105         System.Standard_Library.Adafinal directly. If the library needs
1106         finalization actions, create the sequence of finalization calls.
1107         (Gen_Output_File_Ada): Alphabetize local variables and constants.
1108         Generate a with clause for System.Soft_Links when compiling for a VM.
1109         Remove the code which imports System.Standard_Library.Adafinal as
1110         Do_Finalize. Generate the library finalization routine.
1111         (Gen_Output_File_C): Add new local constant Needs_Library_Finalization.
1112         If the library needs finalization actions, create all the definitions
1113         of library- level finalizers.
1114         (Has_Finalizer): New routine. Determines whether at least one compiled
1115         unit has a library-level finalizer.

2026
2027         * sem_ch8.adb (Analyze_Object_Renaming): if the renamed object is an
2028         explicit dereference of an unconstrained type, create a constrained

2044         low bound is not known at compile time but they have no others choice.
2045         Done because in this case the bounds can be obtained directly from the

2062
2063         * sem_ch3.adb (Build_Derived_Record_Type): Test the Derive_Subps formal
2064         as a condition for the delayed call to Derived_Subprograms done for the
2065         case of the rewriting of a derived type that constrains the
2066         discriminants of its parent type.
2067         Avoids redundant subprogram derivations for private subtype derivations.
2068

2070

2138
2139 2011-08-03  Ed Schonberg  <schonberg@adacore.com>
2140
2141         * sem_res.adb (Set_String_Literal_Subtype): if index type is an integer
2142         type, always use 1 as the lower bound or string, even if lower bound of
2143         context is not static, to handle properly null strings in a non-static
2144         context.
2145
2146 2011-08-03  Bob Duff  <duff@adacore.com>
2147
2148         * sem_prag.adb (Resolve_Aggregate): An array aggregate with 'others' is
2149         always legal on the right-hand side of an assignment statement; there
2150         is always an applicable index constraint in this case. Therefore, the
2151         check for Pkind = N_Assignment_Statement is now unconditional -- it
2152         doesn't depend on whether Is_Constrained (Typ).
2153
2154 2011-08-03  Robert Dewar  <dewar@adacore.com>
2155
2156         * exp_ch5.adb, sem_prag.adb, exp_ch4.adb: Minor reformatting.

2158 2011-08-03  Ed Schonberg  <schonberg@adacore.com>
2159
2160         * sem_ch3.adb (Build_Itype_Reference): do not create an itype reference
2161         for an itype created within a generic unit.
2162
2163 2011-08-03  Eric Botcazou  <ebotcazou@adacore.com>
2164
2165         * gnat_ugn.texi (Switches for gcc): Make it clearer that -fno-inline
2166         suppresses all inlining.
2167
2168 2011-08-03  Robert Dewar  <dewar@adacore.com>
2169
2170         * sem_ch3.adb, sem_res.adb, exp_ch13.adb, exp_disp.adb,

2172
2173 2011-08-03  Thomas Quinot  <quinot@adacore.com>
2174
2175         * exp_ch5.adb (Expand_N_Assignment_Statement): Do not force inlining of
2176         tagged assignment when discriminant checks are suppressed. This is
2177         useless and extremely costly in terms of static stack usage.
2178
2179 2011-08-03  Bob Duff  <duff@adacore.com>
2180
2181         * sem_prag.adb (Get_Base_Subprogram): Do not follow Alias for instances
2182         of generics, because this leads to the wrong entity in the wrong scope,
2183         causing (e.g.) pragma Export_Procedure to get an error if the entity is
2184         an instance.
2185         (Process_Interface_Name): Follow Alias for instances of generics, to
2186         correct for the above change.
2187
2188 2011-08-03  Ed Schonberg  <schonberg@adacore.com>
2189
2190         * exp_ch4.adb (Expand_N_Selected_Component): If the discriminant value
2191         is an integer literal it is always safe to replace the reference. In
2192         addition, if the reference appears in the generated code for an object
2193         declaration it is necessary to copy because otherwise the reference
2194         might be to the uninitilized value of the discriminant of the object
2195         itself.
2196
2197 2011-08-03  Pascal Obry  <obry@adacore.com>
2198
2199         * adaint.c (__gnat_is_executable_file_attr): Fix Win32 circuitry when no
2200         ACL used, in this case we want to check for ending .exe, not .exe
2201         anywhere in the path.
2202

2204
2205         * tree_io.ads (ASIS_Version_Number): Update because of the changes in
2206         the tree structure (semantic decoration of references to record
2207         discriminants).
2208
2209 2011-08-03  Gary Dismukes  <dismukes@adacore.com>
2210
2211         * sem_aggr.adb (Analyze_Array_Aggregate): When checking the discrete
2212         choices of a named array aggregate, bail out when any choices are
2213         marked as Errors_Posted.
2214
2215 2011-08-03  Ed Schonberg  <schonberg@adacore.com>
2216
2217         * exp_ch13.adb (Expand_N_Freeze_Entity): cleanup determination of scope
2218         in which entity is frozen, to handle properly loop variables in
2219         iterators.
2220
2221 2011-08-03  Ed Schonberg  <schonberg@adacore.com>
2222
2223         * sem_res.adb (Set_String_Literal_Subtype): if the lower bound of the
2224         subtype is not static, compute the upper bound using attributes, to
2225         handle properly index types that are not integer types.
2226
2227 2011-08-03  Bob Duff  <duff@adacore.com>
2228
2229         * gnat_rm.texi, gnat_ugn.texi: Fix some dangling URLs.

2233
2234         * sem_ch3.adb (Build_Discriminant_Constraints): Only use
2235         Original_Discriminant if within an instance.
2236         * sem_ch4.adb (Analyze_Selected_Component): Ditto.
2237

2243
2244         * exp_disp.adb (Check_Premature_Freezing): diagnose the presence of a

2252 2011-08-03  Ed Schonberg  <schonberg@adacore.com>
2253
2254         * sem_ch3.adb (Analyze_Object_Declaration): if a constant object of an
2255         unconstrained type with discriminants is initialized with an aggregate,
2256         use the constrained subtype of the aggregate as the type of the object,
2257         because it is immutable, and this allows the back-end to generate no
2258         code for the object declaration.
2259
2260 2011-08-03  Robert Dewar  <dewar@adacore.com>
2261
2262         * exp_ch4.adb (Optimize_Length_Check): Fix bad handling of case where

2268         (Expand_Dispatching_Constructor_Call): Disable expansion of

2796
2797         * sem_ch5.adb (Analyze_Loop_Statement):  If the iteration scheme is an
2798         Ada2012 iterator, the loop will be rewritten during expansion into a
2799         while loop with a cursor and an element declaration. Do not analyze the
2800         body in this case, because if the container is for indefinite types the
2801         actual subtype of the elements will only be determined when the cursor
2802         declaration is analyzed.

2810
2811         * sem_ch3.adb (Check_Ops_From_Incomplete_Type): Remove call to
2812         Prepend_Element, since this can result in the operation getting the
2813         wrong slot in the full type's dispatch table if the full type has
2814         inherited operations. The incomplete type's operation will get added
2815         to the proper position in the full type's primitives
2816         list later in Sem_Disp.Check_Operation_From_Incomplete_Type.
2817         (Process_Incomplete_Dependents): Add Is_Primitive test when checking for
2818         dispatching operations, since there are cases where nonprimitive
2819         subprograms can get added to the list of incomplete dependents (such
2820         as subprograms in nested packages).
2821         * sem_ch6.adb (Process_Formals): First, remove test for being in a
2822         private part when determining whether to add a primitive with a
2823         parameter of a tagged incomplete type to the Private_Dependents list.
2824         Such primitives can also occur in the visible part, and should not have
2825         been excluded from being private dependents.
2826         * sem_ch7.adb (Uninstall_Declarations): When checking the rule of
2827         RM05-3.10.1(9.3/2), test that a subprogram in the Private_Dependents
2828         list of a Taft-amendment incomplete type is a primitive before issuing
2829         an error that the full type must appear in the same unit. There are
2830         cases where nonprimitives can be in the list (such as subprograms in
2831         nested packages).
2832         * sem_disp.adb (Derives_From): Use correct condition for checking that
2833         a formal's type is derived from the type of the corresponding formal in
2834         the parent subprogram (the condition was completely wrong). Add
2835         checking that was missing for controlling result types being derived
2836         from the result type of the parent operation.

2844 2011-08-02  Yannick Moy  <moy@adacore.com>
2845
2846         * sem_res.adb (Resolve_Logical_Op): ensure N is a binary operator
2847         before accessing operands.
2848         * sem_util.adb (Is_SPARK_Initialization_Expr): follow original nodes to
2849         decide whether an initialization expression respects SPARK rules, as
2850         the plain node is the expanded one. This allows for more valid warnings
2851         to be issued.
2852         * gnat_rm.texi: Minor update.
2853
2854 2011-08-02  Arnaud Charlet  <charlet@adacore.com>

2864
2865         * exp_ch5.adb (Expand_Iterator_Loop): Reformatting. Wrap the original

2867         the element type is controlled.

2874
2875         * sem_aggr.adb (Add_Association): if the association has a box and no
2876         expression, use the Sloc of the aggregate itself for the new
2877         association.
2878         * errout.adb (First_Node): Exclude nodes with no Sloc, and always use
2879         the Original_Node.
2880

2882
2883         * exp_ch5.adb (Expand_Iterator_Loop): Code cleanup and refactoring.
2884         When a container is provided via a function call, generate a renaming
2885         of the function result. This avoids the creation of a transient scope
2886         and the premature finalization of the container.
2887         * exp_ch7.adb (Is_Container_Cursor): Removed.
2888         (Wrap_Transient_Declaration): Remove the supression of the finalization
2889         of the list controller when the declaration denotes a container cursor,
2890         it is not needed.
2891
2892 2011-08-02  Yannick Moy  <moy@adacore.com>
2893
2894         * restrict.adb (Check_Formal_Restriction): only issue a warning if the

2896         * sem_aggr.adb
2897         (Resolve_Array_Aggregate): refine the check for a static expression, to

2899         * sem_ch3.adb, sem_ch3.ads (Analyze_Component_Declaration,
2900         Array_Type_Declaration): postpone the test for the type being a subtype
2901         mark after the type has been resolved, so that component-selection and
2902         expanded-name are discriminated.
2903         (Make_Index, Process_Range_Expr_In_Decl): add a parameter In_Iter_Schm
2904         to distinguish the case of an iteration scheme, so that an error is
2905         issed on a non-static range in SPARK except in an iteration scheme.
2906         * sem_ch5.adb (Analyze_Iteration_Scheme): call Make_Index with
2907         In_Iter_Schm = True.

2909         user-defined operators so that they are allowed in renaming

2911         (Find_Selected_Component): refine the check for prefixing of operators
2912         so that they are allowed in renaming. Move the checks for restrictions
2913         on selector name after analysis discriminated between
2914         component-selection and expanded-name.
2915         * sem_res.adb (Resolve_Op_Concat_Arg): do not issue a warning on
2916         concatenation argument of string type if it is static.
2917         * sem_util.adb, sem_util.ads
2918         (Check_Later_Vs_Basic_Declarations): add a new function
2919         Is_Later_Declarative_Item to decice which declarations are allowed as
2920         later items, in the two different modes Ada 83 and SPARK. In the SPARK
2921         mode, add that renamings are considered as later items.
2922         (Enclosing_Package): new function to return the enclosing package
2923         (Enter_Name): correct the rule for homonyms in SPARK
2924         (Is_SPARK_Initialization_Expr): default to returning True on nodes not
2925         from source (result of expansion) to avoid issuing wrong warnings.

2949         * par-ch3.adb (P_Delta_Constraint): remove check in SPARK mode that the
2950         expression is a simple expression. This check cannot be performed in
2951         the semantics, so just drop it.

2953         discriminant is a subtype mark to Analyze_Subtype_Declaration in the

2955         * par-ch4.adb (P_Name): move checks that a selector name is not
2956         character literal or an operator symbol to Find_Selected_Component in
2957         the semantics
2958         * par-ch5.adb (Parse_Decls_Begin_End): move check that basic
2959         declarations are not placed after later declarations in a separate
2960         procedure in Sem_Util (possibly not the best choice?), to be used both
2961         during parsing, for Ada 83 mode, and during semantic analysis, for
2962         SPARK mode.
2963         * par-endh.adb (Check_End): move check that end label is not missing
2964         to Process_End_Label in the semantics

2969         parameter Force to issue the error message even on internal node (used
2970         for generated end label). Call Check_Restriction to check when an error
2971         must be issued. In SPARK mode, issue an error message even if the
2972         restriction is not set.
2973         (Check_Restriction): new procedure with an additional out parameter to
2974         inform the caller that a message has been issued

2976         * sem_attr.adb (Analyze_Attribute): call Check_Formal_Restriction
2977         instead of issuing an error message directly
2978         * sem_ch3.adb (Analyze_Declarations): move here the check that basic
2979         declarations are not placed after later declarations, by calling
2980         Check_Later_Vs_Basic_Declarations
2981         (Analyze_Subtype_Declaration): move here the check that an index or
2982         discriminant constraint must be a subtype mark. Change the check that
2983         a subtype of String must start at one so that it works on subtype marks.
2984         * sem_ch4.adb (Analyze_Call): move here the check that a named
2985         association cannot follow a positional one in a call
2986         * sem_ch5.adb (Check_Unreachable_Code): call Check_Formal_Restriction
2987         instead of issuing an error message directly

2989         selector name is not a character literal or an operator symbol. Move
2990         here the check that the prefix of an expanded name cannot be a
2991         subprogram or a loop statement.
2992         * sem_util.adb, sem_util.ads (Check_Later_Vs_Basic_Declarations): new
2993         procedure called from parsing and semantics to check that basic

5997
5998         * sem_ch13.adb (Analyze_Attribute_Definition_Clause): Ignore
5999         size/alignment related attributes in CodePeer_Mode.
6000
6001 2011-08-02  Gary Dismukes  <dismukes@adacore.com>
6002
6003         * sem_ch3.adb (Check_Ops_From_Incomplete_Type): Remove call to
6004         Prepend_Element, since this can result in the operation getting the
6005         wrong slot in the full type's dispatch table if the full type has
6006         inherited operations. The incomplete type's operation will get added
6007         to the proper position in the full type's primitives
6008         list later in Sem_Disp.Check_Operation_From_Incomplete_Type.
6009         (Process_Incomplete_Dependents): Add Is_Primitive test when checking for
6010         dispatching operations, since there are cases where nonprimitive
6011         subprograms can get added to the list of incomplete dependents (such
6012         as subprograms in nested packages).
6013         * sem_ch6.adb (Process_Formals): First, remove test for being in a
6014         private part when determining whether to add a primitive with a
6015         parameter of a tagged incomplete type to the Private_Dependents list.
6016         Such primitives can also occur in the visible part, and should not have
6017         been excluded from being private dependents.
6018         * sem_ch7.adb (Uninstall_Declarations): When checking the rule of
6019         RM05-3.10.1(9.3/2), test that a subprogram in the Private_Dependents
6020         list of a Taft-amendment incomplete type is a primitive before issuing
6021         an error that the full type must appear in the same unit. There are
6022         cases where nonprimitives can be in the list (such as subprograms in
6023         nested packages).
6024         * sem_disp.adb (Derives_From): Use correct condition for checking that
6025         a formal's type is derived from the type of the corresponding formal in
6026         the parent subprogram (the condition was completely wrong). Add
6027         checking that was missing for controlling result types being derived
6028         from the result type of the parent operation.
6029
6030 2011-08-02  Yannick Moy  <moy@adacore.com>

6036 2011-08-02  Yannick Moy  <moy@adacore.com>
6037
6038         * sem_res.adb (Resolve_Logical_Op): ensure N is a binary operator
6039         before accessing operands.
6040         * sem_util.adb (Is_SPARK_Initialization_Expr): follow original nodes to
6041         decide whether an initialization expression respects SPARK rules, as
6042         the plain node is the expanded one. This allows for more valid warnings
6043         to be issued.
6044         * gnat_rm.texi: Minor update.
6045
6046 2011-08-02  Arnaud Charlet  <charlet@adacore.com>
6047

6056
6057         * exp_ch5.adb (Expand_Iterator_Loop): Reformatting. Wrap the original
6058         loop statements and the element renaming declaration with a block when
6059         the element type is controlled.
6060
6061 2011-08-02  Yannick Moy  <moy@adacore.com>

6065 2011-08-02  Ed Schonberg  <schonberg@adacore.com>
6066
6067         * sem_aggr.adb (Add_Association): if the association has a box and no
6068         expression, use the Sloc of the aggregate itself for the new
6069         association.
6070         * errout.adb (First_Node): Exclude nodes with no Sloc, and always use
6071         the Original_Node.
6072
6073 2011-08-02  Hristian Kirtchev  <kirtchev@adacore.com>
6074
6075         * exp_ch5.adb (Expand_Iterator_Loop): Code cleanup and refactoring.
6076         When a container is provided via a function call, generate a renaming
6077         of the function result. This avoids the creation of a transient scope
6078         and the premature finalization of the container.
6079         * exp_ch7.adb (Is_Container_Cursor): Removed.
6080         (Wrap_Transient_Declaration): Remove the supression of the finalization
6081         of the list controller when the declaration denotes a container cursor,
6082         it is not needed.
6083
6084 2011-08-02  Yannick Moy  <moy@adacore.com>
6085
6086         * restrict.adb (Check_Formal_Restriction): only issue a warning if the
6087         node is from source, instead of the original node being from source.
6088         * sem_aggr.adb
6089         (Resolve_Array_Aggregate): refine the check for a static expression, to
6090         recognize also static ranges
6091         * sem_ch3.adb, sem_ch3.ads (Analyze_Component_Declaration,
6092         Array_Type_Declaration): postpone the test for the type being a subtype
6093         mark after the type has been resolved, so that component-selection and
6094         expanded-name are discriminated.
6095         (Make_Index, Process_Range_Expr_In_Decl): add a parameter In_Iter_Schm
6096         to distinguish the case of an iteration scheme, so that an error is
6097         issed on a non-static range in SPARK except in an iteration scheme.
6098         * sem_ch5.adb (Analyze_Iteration_Scheme): call Make_Index with
6099         In_Iter_Schm = True.
6100         * sem_ch6.adb (Analyze_Subprogram_Specification): refine the check for
6101         user-defined operators so that they are allowed in renaming
6102         * sem_ch8.adb
6103         (Find_Selected_Component): refine the check for prefixing of operators
6104         so that they are allowed in renaming. Move the checks for restrictions
6105         on selector name after analysis discriminated between
6106         component-selection and expanded-name.
6107         * sem_res.adb (Resolve_Op_Concat_Arg): do not issue a warning on
6108         concatenation argument of string type if it is static.
6109         * sem_util.adb, sem_util.ads
6110         (Check_Later_Vs_Basic_Declarations): add a new function
6111         Is_Later_Declarative_Item to decice which declarations are allowed as
6112         later items, in the two different modes Ada 83 and SPARK. In the SPARK
6113         mode, add that renamings are considered as later items.
6114         (Enclosing_Package): new function to return the enclosing package
6115         (Enter_Name): correct the rule for homonyms in SPARK
6116         (Is_SPARK_Initialization_Expr): default to returning True on nodes not
6117         from source (result of expansion) to avoid issuing wrong warnings.

6133         * exp_ch7.adb (Is_Container_Cursor): New routine.
6134         (Wrap_Transient_Declaration): Supress the finalization of the list
6135         controller when the declaration denotes a container cursor.
6136
6137 2011-08-02  Yannick Moy  <moy@adacore.com>

6141         * par-ch3.adb (P_Delta_Constraint): remove check in SPARK mode that the
6142         expression is a simple expression. This check cannot be performed in
6143         the semantics, so just drop it.
6144         (P_Index_Or_Discriminant_Constraint): move check that the index or
6145         discriminant is a subtype mark to Analyze_Subtype_Declaration in the
6146         semantics. Other cases were previously checked in the semantics.
6147         * par-ch4.adb (P_Name): move checks that a selector name is not
6148         character literal or an operator symbol to Find_Selected_Component in
6149         the semantics
6150         * par-ch5.adb (Parse_Decls_Begin_End): move check that basic
6151         declarations are not placed after later declarations in a separate
6152         procedure in Sem_Util (possibly not the best choice?), to be used both
6153         during parsing, for Ada 83 mode, and during semantic analysis, for
6154         SPARK mode.
6155         * par-endh.adb (Check_End): move check that end label is not missing
6156         to Process_End_Label in the semantics
6157         * par-prag.adb (Process_Restrictions_Or_Restriction_Warnings): remove

6161         parameter Force to issue the error message even on internal node (used
6162         for generated end label). Call Check_Restriction to check when an error
6163         must be issued. In SPARK mode, issue an error message even if the
6164         restriction is not set.
6165         (Check_Restriction): new procedure with an additional out parameter to
6166         inform the caller that a message has been issued

6168         * sem_attr.adb (Analyze_Attribute): call Check_Formal_Restriction
6169         instead of issuing an error message directly
6170         * sem_ch3.adb (Analyze_Declarations): move here the check that basic
6171         declarations are not placed after later declarations, by calling
6172         Check_Later_Vs_Basic_Declarations
6173         (Analyze_Subtype_Declaration): move here the check that an index or
6174         discriminant constraint must be a subtype mark. Change the check that
6175         a subtype of String must start at one so that it works on subtype marks.
6176         * sem_ch4.adb (Analyze_Call): move here the check that a named
6177         association cannot follow a positional one in a call
6178         * sem_ch5.adb (Check_Unreachable_Code): call Check_Formal_Restriction
6179         instead of issuing an error message directly
6180         * sem_ch8.adb (Find_Selected_Component): move here the check that a
6181         selector name is not a character literal or an operator symbol. Move
6182         here the check that the prefix of an expanded name cannot be a
6183         subprogram or a loop statement.
6184         * sem_util.adb, sem_util.ads (Check_Later_Vs_Basic_Declarations): new
6185         procedure called from parsing and semantics to check that basic
6186         declarations are not placed after later declarations
6187         (Process_End_Label): move here the check that end label is not missing

6192         representation clause in codepeer mode, since it confuses CodePeer and
6193         does not bring useful info.
