1038 2015-11-12 Ed Schonberg <schonberg@adacore.com>
1040 * sem_ch3.adb (Analyze_Number_Declaration): Call Analyze_Dimension,
1041 to propagate dimension information from expression to named
1042 number.
1043 * sem_dim.ads: Documentation: number declaration and explicit
1044 dereference can carry dimension information.
1045 * sem_dim.adb (Analyze_Dimension_Number_Declaration): New
1046 procedure, to propagate dimension information from expression
1047 of declaration to named number, whose type becomes one of the
1048 dimensioned base types rather than universal real.
1049 (Analyze_Dimension_Binary_Op):
1050 a) If one operand is a literal that is the value of a declared
1051 constant after constant-foloding, use the dimensions of the
1052 declared constant.
1053 b) If an operand is a literal that is a contant-folded expression,
1054 and expander is active, do not report a dimension mismatch if
1055 literal does not carry them, because dimension matching will
1056 have been checked previously.
1058 2015-11-12 Ed Schonberg <schonberg@adacore.com>
1060 * sem_ch8.adb (Find_Selected_Component): In a synchronized
1061 body, a reference to an operation of an object of the same
1062 synchronized type was always interpreted as a reference to the
1063 current instance. This is not always the case, as the prefix of
1064 the reference may designate an object of the same type declared
1065 in the enclosing context prior to the body.
1067 2015-11-12 Arnaud Charlet <charlet@adacore.com>

1096 GNAT_Extended_Ravenscar profile.
1098 2015-11-12 Ed Schonberg <schonberg@adacore.com>
1100 * sem_warn.adb (Warn_On_Unreferenced_Entity): If the entity is an
1101 Out_Parameter the front-end does not emit any warning on it, so
1102 do not suppress warnings on the entity because the backend might
1103 be able to determine an uninitialized path and warn accordingly.
1105 2015-11-12 Ed Schonberg <schonberg@adacore.com>
1107 * sem_ch4.adb (Analyze_Selected_Component): Diagnose an attempt
1108 to reference an internal entity from a synchronized type from

1114 * s-stchop-vxworks.adb: Clean up in stack checking code.
1116 2015-11-12 Gary Dismukes <dismukes@adacore.com>
1118 * exp_ch6.adb (Is_Build_In_Place_Function_Call):
1119 Test Expression (N) in N_Type_Conversion cases as well,
1120 since conversions can occur in actual parameter contexts.
1121 (Make_Build_In_Place_Call_In_Anonymous_Context): Retrieve
1122 function call from Expression (Func_Call) when Nkind (Func_Call)
1123 is N_Type_Conversion, since conversions are allowed in "anonymous"

1139 * exp_attr.adb (Compile_Stream_Body_In_Scope): Do not install
1140 full view of a type that has pragma Stream_Convert, because

1142 the type.
1144 2015-11-12 Jerome Lambourg <lambourg@adacore.com>
1146 * init.c: Do not try to mess with the MSR values in RTP mode:

1169 2015-11-12 Ed Schonberg <schonberg@adacore.com>
1171 * exp_intr.adb: Add legality checks on calls to a
1172 Generic_Dispatching_Constructor: the given tag must be defined,

1176 2015-11-12 Ed Schonberg <schonberg@adacore.com>
1178 * sem_ch4.adb (Try_Container_Indexing, Constant_Indexing_OK): If
1179 the context is an overloaded call, assume that Constant_Indexing

1181 corresponding to the indexing expression.
1183 2015-11-12 Jerome Lambourg <lambourg@adacore.com>
1185 * init.c (__gnat_error_handler): Force the SPE bit of the MSR
1186 when executing on e500v2 CPU.

1286 couple of typos.
1287 * sem_util.adb (Note_Possible_Modification): Overhaul the condition for
1288 the warning on modified constants and use Find_Overlaid_Entity instead
1289 of doing it manually.

3173 SS_Release for a block statement enclosing the return statement in the
3174 case where a build-in-place function return is returning

3177 It was already being set for the function itself, and it was
3178 already set correctly for blocks in the non-build-in-place case
3179 (in Expand_Simple_Function_Return).
3180 (Set_Enclosing_Sec_Stack_Return): New procedure to perform

3903 * gcc-interface/Makefile.in: Update targets.
3905 2015-10-20 Bob Duff <duff@adacore.com>
3907 * sem_ch13.adb (Analyze_One_Aspect): Avoid
3908 analyzing the expression in a 'Disable_Controlled attribute when
3909 Expander_Active is False, because otherwise, we get errors about
3910 nonstatic expressions in pragma-Preelaborate generic packages.
3911 * restrict.ads: minor whitespace cleanup in comment
3913 2015-10-20 Bob Duff <duff@adacore.com>
3915 * a-conhel.adb: Remove "use SAC;", because otherwise the compiler
3916 complains about use clauses in run-time units. Use "use type"
3917 instead.
3918 * a-btgbso.adb, a-btgbso.ads, a-cbdlli.adb, a-cbdlli.ads,

3934 * a-rbtgso.adb, a-rbtgso.ads: Change all the predefined containers
3935 to share the tampering machinery in Ada.Containers.Helpers. This
3936 reduces the amount of duplicated code, and takes advantage of
3937 efficiency improvements in Helpers.
3938 Protect all run-time checks and supporting machinery with "if
3939 Checks" or "if T_Check", so this code can be suppressed with
3940 pragma Suppress or -gnatp.
3941 Add Pseudo_Reference and Get_Element_Access to remaining
3942 containers, so that the compiler can optimize "for ... of" loops.
3944 2015-10-20 Bob Duff <duff@adacore.com>
3946 * a-contai.adb, a-coinve.ads, a-contai.ads, a-conhel.adb, a-conhel.ads,
3947 Makefile.rtl, a-convec.ads: Move helper code from Ada.Containers to a
3948 new package Ada.Containers.Helpers, because otherwise it's not
3949 visible everywhere it needs to be (e.g. in the package
3950 Ada.Containers.Red_Black_Trees, Generic_Tree_Types wants to have
3951 a component of type Tamper_Counts).
3953 2015-10-20 Ed Schonberg <schonberg@adacore.com>
3955 * sem_type.adb (Intersect_Types): Specialize error message when
3956 one operand is a limited view which is a priori incompatible
3957 with all other named types.

4032 2015-10-20 Gary Dismukes <dismukes@adacore.com>
4034 * sem_ch13.adb: Minor reference change (RM => AARM).
4036 2015-10-20 Eric Botcazou <ebotcazou@adacore.com>
4038 * make.adb (Check): Skip multilib switches reinstated by the
4039 compiler only when counting the number of switches, since it is

4044 * einfo.adb: Add extra assertion for small clause.
4045 * cstand.adb: Minor style fix in comment.

4054 given as attribute references.
4056 2015-10-20 Bob Duff <duff@adacore.com>
4058 * a-coinve.ads, a-coinve.adb: Do the same efficiency
4059 improvements that were already done in the definite case
4060 (Ada.Containers.Vectors, i.e. a-convec). This includes the
4061 ability to suppress checks, the fast path for Append, inlining
4062 as appropriate, and special-casing of "for ... of" loops. Reuse
4063 the tampering machinery that is now in Ada.Containers. Simplify
4064 many operations.
4065 * a-convec.ads, a-convec.adb: Change the code to be more similar
4066 to a-coinve.
4067 * a-finali.ads, a-finali.adb: Expose the "null"-ness of the
4068 operations. This may enable optimizations in the future, and
4069 seems cleaner anyway.
4071 2015-10-20 Ed Schonberg <schonberg@adacore.com>
4073 * sem_ch13.adb (Is_Operational_Item): Attributes related to
4074 Ada 2012 iterators are operational items, and can be specified
4075 on partial views.

4079 * sem_prag.adb (Check_Usage): Update the calls to Usage_Error.
4080 (Usage_Error): Remove formal parameter Item. Emit a clearer message
4081 concerning a missing dependency item and place it on the related pragma.
4083 2015-10-20 Bob Duff <duff@adacore.com>
4085 * debug.adb, expander.adb: Implement -gnatd.B switch, which
4086 triggers a bug box when an abort_statement is seen. This is
4087 useful for testing Comperr.Compiler_Abort.
4088 * gnat1drv.adb: Trigger bug box on all exceptions other than
4089 Unrecoverable_Error.
4091 2015-10-20 Thomas Quinot <quinot@adacore.com>

4104 to set a build environment key=value pair)
4105 * bindusg.adb: Document the above
4107 2015-10-20 Vincent Celier <celier@adacore.com>

4110 entity as Pure if Debug_Flag_U is set.
4112 2015-10-20 Bob Duff <duff@adacore.com>
4114 * output.adb (Write_Int): Work with negative numbers in order to avoid
4115 negating Int'First and thereby causing overflow.

4139 classification pragmas.
4141 2015-10-20 Ed Schonberg <schonberg@adacore.com>
4143 * sem_ch3.adb (Analyze_Declarations); At the of the visible part,
4144 perform name resolution on the expressions in aspects of visible
4145 entities.
4146 * sem_ch13.ads, sem_ch13.adb (Resolve_Aspect_Expressions): Resolve
4147 expressions in aspects independently of whether corresponding
4148 entity is frozen. Used to complete name resolution of aspect
4149 expressions for entities declared in the visible part of a
4150 package or generic package declaration.
4152 2015-10-20 Vincent Celier <celier@adacore.com>

4160 2015-10-20 Eric Botcazou <ebotcazou@adacore.com>
4162 * gnatlink.adb (Gnatlink): Do not translate --RTS switch
4163 for the linker and instead pass the switches that were
4164 reinstated by the compiler.
4166 2015-10-20 Bob Duff <duff@adacore.com>
4168 * a-contai.ads, a-convec.ads: Move Count_Type_Last from
4169 a-convec.ads to a-contai.ads, so other containers can refer to it.
4171 2015-10-20 Ed Schonberg <schonberg@adacore.com>
4173 * sem_ch3.adb (Check_Nonoverridable_Aspects): New procedure within
4174 Analyze_Full_Type_ Declaration, used to apply legality rules in
4175 13,1,1 (18.3.3) concerning aspects that cannot be overridden in
4176 a type extension.
4177 (Check_Duplicate_Aspects): It is not legal to specify the
4178 Implicit_Dereference aspect on a full view if partial view has
4179 known discriminants.
4180 * sem_ch13.adb (Analyze_Aspect_Implicit_Dereference): Verify that
4181 the specification of the aspect on a derived type confirms the
4182 value of the inherited one.
4183 * sem_util.adb (Reference_Discriminant): Return empty if none
4184 specified.
4186 2015-10-20 Thomas Quinot <quinot@adacore.com>

4208 (Check_Aspect_At_Freeze_Point): Aspect Constant_After_Elaboration
4209 does not require special processing at freeze time.
4210 * sem_prag.adb (Analyze_Pragma): Add processing for pragma
4211 Constant_After_Elaboration. Use routine Find_Related_Context to
4212 retrieve the context of pragma Part_Of.
4213 (Duplication_Error): Update comment on usage.
4214 (Find_Related_Context): New routine.
4215 * sem_prag.ads Add an entry for Constant_After_Elaboration
4216 in table Aspect_Specifying_Pragma.
4217 (Analyze_Contract_Cases_In_Decl_Part): Update the comment on usage.
4218 * sem_util.adb (Add_Contract_Item): Add processing for pragma

4224 2015-10-16 Vincent Celier <celier@adacore.com>
4226 * prj-pp.adb (Pretty_Print.Print): Correctly display extending

4256 transient scope with the renaming object declararation.
4257 * exp_util.adb (Insert_Actions): if the enclosing interator
4258 loop is marked as requiring the secondary stack then attach the

4265 2015-10-16 Ed Schonberg <schonberg@adacore.com>
4267 * sem_ch3.adb (Replace_Anonymous_Access_To_Protected_Subprogram):
4268 If anonymous type is component type of array type declaration,
4269 analyze its declaration in the current scope, not the enclosing
4270 one.
4272 2015-10-16 Gary Dismukes <dismukes@adacore.com>
4274 * prj.adb, sem_util.adb, exp_ch6.adb: Minor reformatting.
4276 2015-10-16 Ed Schonberg <schonberg@adacore.com>
4278 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Modify

4280 whose elements are indefinite types.
4282 2015-10-16 Doug Rupp <rupp@adacore.com>
4284 * s-taprop-linux.adb (Monotonic_Clock): Call clock_gettime
4285 instead of gettimeofday.

4287 (clock_gettime): New imported subprogram.
4289 2015-10-16 Hristian Kirtchev <kirtchev@adacore.com>
4291 * exp_ch6.adb (Make_Build_In_Place_Call_In_Object_Declaration):
4292 Indefinite or limited library level objects are now returned on
4293 the heap.
4294 * exp_ch7.adb (Build_Finalization_Master): Add formal
4295 parameter For_Lib_Level. Add context specific insertion for a
4296 finalization master created for an access result type related
4297 to a build-in-place function call used to initialize a library
4298 level object.
4299 * exp_ch7.ads (Build_Finalization_Master): Add formal parameter

4303 2015-10-16 Emmanuel Briot <briot@adacore.com>
4305 * prj.adb (For_Every_Project_Imported_Context): Fix handling
4306 of aggregated projects with duplicate names.
4307 * a-ngelfu.ads: Minor whitespace fix.
4309 2015-10-16 Ed Schonberg <schonberg@adacore.com>
4311 * sem_ch13.adb (Build_Predicate_Functions): The expression for
4312 the predicate is side-effect free if it does not contain any
4313 variable references.
4315 2015-10-16 Bob Duff <duff@adacore.com>
4317 * a-convec.adb ("="): Previous version depended
4318 on "=" composing, but that doesn't quite work -- we want the "="
4319 operator passed in to the generic. So we need a loop after all.
4321 2015-10-16 Yannick Moy <moy@adacore.com>
4323 * sem_util.adb (Is_Object_Reference): Attribute 'Loop_Entry produces
4324 an object.
4325 * sem_ch6.adb: Minor fix in comment.
4327 2015-10-16 Bob Duff <duff@adacore.com>
4329 * a-contai.ads: Add two check names: Container_Checks and
4330 Tampering_Check. Move the tampering check machinery from
4331 Ada.Containers.Vectors to Ada.Containers. Later we can share it
4332 with other containers.
4333 Disable the tampering machinery in the presence of
4334 Suppress(Tampering_Check).
4335 Simplify the implementation of tampering checks. E.g. use RAII
4336 to make incrementing/decrementing of the counts more concise.
4337 * a-contai.adb: New package body, implementing the above.
4338 * a-convec.ads, a-convec.adb: Use tampering check machinery
4339 in Ada.Containers.
4340 Disable all checking code when checks are suppressed.
4341 Simplify many of the operations. Implement "&" in terms of Append,
4342 rather than "by hand".
4343 Remove: function "=" (L, R : Elements_Array) return Boolean is
4344 abstract; so we can call the predefined "=" on Elements_Array.
4345 For "=" on Vectors: Previously, we returned True immediately if
4346 Left'Address = Right'Address. That seems like a non-optimization
4347 ("if X = X" is unusual), so removed that. Simplify by using
4348 slice comparison ("=" on Element_Array will automatically call
4349 "=" on the components, even if user defined).
4351 2015-10-16 Ed Schonberg <schonberg@adacore.com>
4353 * sem_ch13.adb (Chek_Record_Representation_Clause): When
4354 iterating over components, skip anonymous subtypes created for
4355 constrained array components.

5258 where the actual subprogram may have different formal names than
5259 those of the primitive operation of the formal type.
5260 b) Defaulted parameters must be taken into account when obtaining

5275 * exp_tss.ads: Minor comment fix.
5276 * exp_ch3.adb (Build_Array_Init_Proc, Build_Record_Init_Proc):
5277 Inline init_procs when the type has controlled parts. Remove
5278 obsolete comments about those init_procs -- init_procs for
5279 such types are no longer complex. A typical init_proc just
5280 initializes the 'Tag field, and calls the parent init_proc
5281 (e.g. for Limited_Controlled), which calls the grandparent
5282 (for Root_Controlled), which does nothing. This all boils down
5283 to one instruction when inlined.
5284 * exp_ch7.adb (Create_Finalizer): Inline the finalizer.
5286 2015-05-28 Ed Schonberg <schonberg@adacore.com>
5288 * sem_ch4.adb (Analyze_Selected_Component): If the type to use
5289 is a derived type and is a generic actual, the selected component
5290 appears within an instance body, and the check over the type
5291 has failed, examine ancestor types for the desired component.
5292 (Find_Component_In_Instance): If record type is a derived type,
5293 examine all ancestors in order to locate desired component.
5295 2015-05-27 H.J. Lu <hongjiu.lu@intel.com>

5333 * par_sco.adb (Process_Decision): Store sloc to
5334 condition/pragmas SCOs associations into a temporary table before
5335 moving them to the SCO_Raw_Hash_Table so that we can back them
5336 out just like we do for SCO entries that are simple decisions
5337 in an expression context.
5339 2015-05-27 Ed Schonberg <schonberg@adacore.com>
5341 * sem_ch6.adb (Process_Formals): A non-private formal type that
5342 is a limited view does not have a list of private dependents.
5344 2015-05-27 Ed Schonberg <schonberg@adacore.com>
5346 * exp_ch5.adb (Expand_N_Case_Statement): If the expression in
5347 the case statement is a compile-time known value, we look for a
5348 corresponding alternative to optimize the case statement into a
5349 single case. If the type has a static predicate and the expression
5350 does not satisfy the predicate, there is no legal alternative and
5351 this optimization is not applicable. Excecution is erroneous,
5352 or else if assertions are enabled, an exception will be raised
5353 earlier, at the point the expression is elaborated.
5355 2015-05-27 Robert Dewar <dewar@adacore.com>

5370 2015-05-26 Bob Duff <duff@adacore.com>
5372 * sem_elab.adb (Check_A_Call): In the case where we're
5373 calling something in an instance of a generic package that is
5374 within this same unit (as the call), make sure we treat it
5375 as a call to an entity within the same unit. That is, call
5376 Check_Internal_Call, rather than putting "Elaborate_All(X)"
5377 on X, which would necessarily result in an elaboration cycle in
5378 static-elaboration mode.
5380 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>

5406 2015-05-26 Eric Botcazou <ebotcazou@adacore.com>
5408 * gcc-interface/trans.c (Attribute_to_gnu) <Attr_Machine>: Do not apply

5451 * gcc-interface/decl.c (gnat_to_gnu_entity): Do not rely on const_flag
5452 to detect constant renamings. Be prepared for specific pattern of
5453 renamed object based on function calls. Create a constant object
5454 for the renaming of a NULL_EXPR or of a CONSTRUCTOR. Adjust calls
5455 to gnat_stabilize_reference and tidy up. Remove redundant tests.
5456 (elaborate_expression_1): Remove obsolete test and tidy up.

5458 parameters passed by reference.

5478 where the enclosing unit must have a regular with_clause on the
5479 relevant unit.
5480 * sem_ch12.adb (Install_Body): Freeze instantation after its
5481 body. Remove useless freeze nodes for incomplete actuals to
5482 prevent multiple generation of internal operations.
5483 (Instantiate_Package_Body): Set sloc of body appropriately when
5484 there are incomplete actuals and the instance body is placed in

5510 * sem_ch13.adb: sem_ch13.adb (Add_Predicates): Undo analysis
5511 of original expression in ASIS mode: does not solve the ASIS
5512 problem of a usable type information, and crashes the back-end
5513 when performing type annotations.

5527 2015-05-26 Bob Duff <duff@adacore.com>
5529 * treepr.adb: Minor improvement to debugging routines (pp, pn)
5530 robustness. Rearrange the code so passing a nonexistent Node_Id

5890 Swap_Private_Dependents): Ensure that both views of the dependent
5891 subtype are immediately visible if we are within their scope. This

5938 checks, that function call, though it is labelled Analyzed to
5939 prevent an infinite recursion, may be rewritten as a temporary
5940 by Remove_Side_Effects. Ensure that the caller has access to
5941 the original function call to continue expansion.
5942 * atree.ads: Minor typo in comment.

6053 has aspect specifications, examine the corresponding list of
6054 representation items to determine whether there is a visible
6055 stream operation. The attribute definition clause generated from
6056 the aspect will be inserted at the freeze point of the type,
6057 which may be in the private part and not directly visible,

6225 on entries, entry families, subprograms and generic subprograms.
6226 * sem_ch12.adb (Analyze_Generic_Subprogram_Declaration):
6227 Minor code reorganization to ensure that the Ekind attribute
6228 of the subprogram entity is set before its formals are
6229 processed. Required to allow the use of the attribute
6230 Has_Out_Or_In_Out_Parameter on the subprogram entity.
6231 * sem_aggr.adb (Resolve_Aggregate, Resolve_Extension_Aggregate):
6232 Perform the check on writable actuals only if the value of some
6233 component of the aggregate involves calling a function with

6246 construct as a node on which the writable actuals check must
6247 be performed.

6249 enclosing construct.
6250 * sem_util.adb (Check_Function_Writable_Actuals): Code cleanup
6251 and reorganization. We skip processing aggregate discriminants
6252 since their precise analysis involves two phases traversal.

6271 operation, replace the names of the actuals in named associations
6272 with the names of the actuals of the subprogram that is eventually
6273 executed. The names of the formals and the defaults can differ
6274 between the two operations when they are operations of a formal
6275 derived type.
6277 2015-05-22 Bob Duff <duff@adacore.com>
6279 * a-convec.ads, a-convec.adb (Append): Check for fast path. Split
6280 out slow path into separate procedure. Inline Append. Fast path
6281 now avoids calling Insert.
6282 (Finalize): Do the busy checking last, so the container gets emptied.
6283 (Insert, Insert_Space): Remove redundancy.
6285 2015-05-22 Robert Dewar <dewar@adacore.com>
6287 * switch-c.adb (Scan_Front_End_Switches): Insist on -gnatc

6312 * exp_aggr.adb (Get_Constraint_Association): If type (of ancestor
6313 composite type) is private, go to full view. This was previously

6331 declarations added for use by performance improvements in exp_ch5.adb.
6332 * snames.ads-tmpl: New names referenced by exp_ch5.adb.
6333 * exp_ch5.adb: Speed up "for ... of" loops for predefined containers.
6334 Instead of doing literally what the RM calls for, we do something
6335 equivalent that avoids expensive operations inside the loop. If the
6336 container package has appropriate Next, Pseudo_Reference,
6337 Element_Access, Get_Element_Access declarations, we invoke the
6338 optimization.
6339 * snames.ads-tmpl: Note speed improvement.
6341 2015-05-22 Eric Botcazou <ebotcazou@adacore.com>

6372 exp_ch4.adb, errout.adb, exp_aggr.adb, sem_ch13.adb: This is a general
6373 change that deals with the fact that most of the special coding for
6374 Atomic should also apply to the case of Volatile_Full_Access.

6423 silently gprclean.
6424 * make.adb (Initialize): For native gnatmake, check for switch -P
6425 and, if found and gprbuild is available, invoke silently gprbuild.

6446 actuals of instance, for later placement of instance body and
6447 freeze nodes for actuals.
6448 (Install_Body): In the presence of actuals that incomplete types
6449 from a limited view, the instance body cannot be placed after
6450 the declaration because full views have not been seen yet. Any
6451 use of the non-limited views in the instance body requires
6452 the presence of a regular with_clause in the enclosing unit,
6453 and will fail if this with_clause is missing. We place the
6454 instance body at the beginning of the enclosing body, which is
6455 the unit being compiled, and ensure that freeze nodes for the
6456 full views of the incomplete types appear before the instance.

7306 * sem_util.adb (Build_Default_Subtype): If the subtype is created
7307 for a record discriminant, do not analyze the declarztion at
7308 once because it is added to the freezing actions of the enclosing

7989 call to String'Input, returning a dynamically sized value on the
7990 secondary stack) will be expanded outside of proper secondary
7991 stack mark/release operations, and will thus cause a secondary
7992 stack leak.

8200 occurrences of the component have the same subtype, rather than

9918 point types.
9919 * set_targ.adb (Long_Double_Index): The index at which "long
9920 double" gets registered in the FPT_Mode_Table. This is useful to

9931 suitable as a basis to construct the standard Ada floating point
9932 type identified by the input T parameter.
9933 (elaboration code): Register_Back_End_Types unconditionally,
9934 so C_Type_For can operate regardless of -gnateT. Do it
9935 early so we can query it for the floating point sizes, via
9936 FPT_Mode_Index_For. Initialize Float_Size, Double_Size and
9937 Long_Double_Size from the FPT_Mode_Table, as cstand will do.
9938 * cstand.adb (Create_Float_Types): Use C_Type_For to determine
9939 which C type should be used as the basis for the construction
9940 of the Standard Ada floating point types.

9960 has been resolved, and replace the standard renaming declaration
9961 with the declaration of wrapper.

9963 make public for use elsewhere.
9964 * sem_ch12.adb (Build_Function_Wrapper, Build_Operator_Wraooer):
