817 comment about the memset case.
819 2018-05-30 Bob Duff <duff@adacore.com>
821 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
822 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
823 We need to analyze it as part of analyzing the block, so that if the
824 call to Element that initializes Elmt_Decl returns on the secondary
825 stack, the block will ss_mark/ss_release. This block is inside the
826 loop; we don't want to leak memory until the loop exits. The purpose
827 of analyzing Elmt_Decl first was to catch the error of modifying it,
828 which is illegal because it's a loop parameter. The above causes us to
829 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
830 it on the Element entity, so we end up with an E_Variable node with the
832 * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.
833 * sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop
834 parameter not allowed" error if Is_Loop_Parameter.
835 * sem_util.adb (Is_Variable): Return False if Is_Loop_Parameter, to
836 trigger the call to Diagnose_Non_Variable_Lhs.

850 2018-05-30 Ed Schonberg <schonberg@adacore.com>
852 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
853 a package body that is a compilation unit may contain blocks that
854 declare local subprograms. In Subprogram_Unnesting Mode such
855 subprograms must be handled as nested inside the (implicit) elaboration
856 procedure that executes that statement part. To handle properly uplevel
857 references we construct that subprogram explicitly, to contain blocks
858 and inner subprograms, The statement part of the compilation unit
859 becomes a call to this subprogram. This is only done if blocks are
860 present in the statement list of the body.

872 for subprogram instantiations to enter callable entity into Subp table.

1136 To_Mixed): New functions.
1137 * osint.adb: Cleanup: use Is_Directory_Separator, which correctly
1138 allows both '\' and '/' on Windows.

1167 references, examine index expressions or associated expressions as well
1168 to record uplevel references.
1169 (Vist_Node): For function and procedure calls, if a formal is an
1170 unconstrained array and the actual is constrained, check whether bounds
1171 of actual have uplevel references.
1173 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1175 * einfo.ads, einfo.adb: Exceptions can be uplevel references, and thus
1176 they can appear as components of activation records.

1182 * exp_ch4.adb (Expand_Composite_Equality): Compute whether the size
1183 depends on a discriminant manually instead of using the predicate
1184 Size_Depends_On_Discriminant in the array type case.
1186 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1188 * exp_unst.adb (Check_Static_Type): For a record subtype, check
1189 discriminant constraints as well.
1190 (Visit_Node): For a selected component, check type of prefix, as is
1191 done for indexed components and slices.
1193 2018-05-28 Javier Miranda <miranda@adacore.com>
1195 * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
1196 value when converting a float value to a fixed-point value. This is
1197 required for CCG because it handles fixed-point types by means of
1198 unsigned integer type variables. The range check is now performed using
1199 the integer value stored in this temporary.
1201 2018-05-28 Yannick Moy <moy@adacore.com>
1203 * sem_util.adb (Is_OK_Volatile_Context): Add attributes First, Last and

1214 (Inherited_Subprograms): Instance of Generic_Inherited_Subprograms with
1215 Sem_Disp.Find_Dispatching_Type.
1216 (Is_Overriding_Subprogram): Instance of
1217 Generic_Is_Overriding_Subprogram with Sem_Disp.Find_Dispatching_Type.
1218 (Inheritance_Utilities_Inst): Instance of Inheritance_Utilities
1219 with Sem_Disp.Find_Dispatching_Type.
1221 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
1223 * exp_ch4.adb (Expand_Composite_Equality): For a composite (or FP)
1224 component type, do not expand array equality using the unconstrained
1225 base type, except for the case where the bounds of the type depend on a
1228 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1230 * einfo.ads, einfo.adb (Needs_Activation_Record): New flag on
1231 access-to-subprogram types, to indicate that an indirect call through
1232 such a type requires an activation record when compiling for LLVM.
1233 * sem_ch3.adb (Access_Subprogram_Declaration): Set new flag as needed.
1235 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1237 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
1238 when bounds of fixed type are static, to remove some spuerfluous
1239 implicit conversions and provide an accurate result when converting
1240 back and forth between the fixed point type and a floating point type.
1242 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1244 * exp_unst.adb (Unnest_Subprogram): Prevent creation of empty
1247 2018-05-28 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
1249 * exp_unst.adb (Check_Static_Type): Add argument to indicate node to be
1250 replaced, if any; all callers changed.
1251 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
1252 constant with private view so we take the address of that entity.
1253 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
1254 any; all callers changed. Handle N_Indexed_Component like
1255 N_Attribute_Reference. Add N_Type_Conversion case.
1256 (Visit_Node): Indexed references can be uplevel if the type isn't
1258 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
1259 been relocated, set first_named pointer in original node as well.
1261 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1263 * exp_aggr.adb (Flatten): Copy tree of expression in a component
1264 association with a range or a set of discrete choices, rather than
1265 relocating the node. This avoids inconsistencies in the tree when
1266 handling nested subprograms with uplevel references for LLVM.
1268 2018-05-28 Arnaud Charlet <charlet@adacore.com>
1270 * exp_util.adb (Possible_Bit_Aligned_Component): Always return False in

1277 2018-05-28 Bob Duff <duff@adacore.com>
1279 * libgnat/a-convec.adb (Query_Element): Minor cleanup: remove an
1280 unnecessary use of 'Unrestricted_Access.
1282 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
1284 * repinfo.adb (Expr_Value_S): New routine.

1288 2018-05-28 Patrick Bernardi <bernardi@adacore.com>
1290 * doc/gnat_ugn/building_executable_programs_with_gnat.rst: Update the
1291 description of the -D binder switch to reflect current usage.
1292 * gnat_ugn.texi: Regenerate.
1294 2018-05-28 Gary Dismukes <dismukes@adacore.com>
1296 * exp_ch3.adb: Minor reformatting

1309 used to determine how to generate an Init_Proc for a given type.
1310 (Needs_Constant_Address): Minor reformatting
1312 (Resolve_Null): Add logic to generate a conditional check in certain cases
1314 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>

1319 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
1321 * sem_prag.adb (Process_Atomic_Independent_Shared_Volatile): Include
1322 the declarations of single concurrent types because they fall in the
1323 category of full type and object declarations.
1325 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
1327 * repinfo.adb (Compute_Max_Length): Skip _Parent component.

1330 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1332 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
1333 includes a call to function to which it applies. This may mean an
1334 omission of an attribute reference 'Result, in particular if the
1335 function is pqrameterless.
1337 2018-05-28 Justin Squirek <squirek@adacore.com>
1339 * sem_ch8.adb (Find_Expanded_Name): Add extra guard to make sure the
1340 misresolved package name is not a case of mistaken identity.
1342 2018-05-28 Yannick Moy <moy@adacore.com>
1344 * sem_res.adb (Resolve_Range): Re-resolve the low bound of a range in
1345 GNATprove mode, as the order of resolution (low then high) means that
1346 all the information is not available when resolving the low bound the
1349 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
1351 * repinfo.adb (List_Array_Info): Start with an explicit blank line and
1352 end with the linker section, if any.
1353 (List_Entities): Do not output the linker section for record types,
1354 array types and variables.
1355 (Print_Expr): Factor out common processing for unary operators and
1356 special values. Adjust and reorder the various cases.
1357 (List_Object_Info): End with the linker section, if any.
1358 (List_Record_Info): Likewise.
1359 (List_Type_Info): Do not start with a blank line.
1361 2018-05-25 Nicolas Roche <roche@adacore.com>
1363 * libgnat/s-valrea.adb (Scan_Real): Abort computation once it is sure
1364 that the result will be either -infinite or +infinite.
1366 2018-05-25 Patrick Bernardi <bernardi@adacore.com>
1368 * libgnat/s-parame.ads, libgnat/s-parame__vxworks.ads,
1369 libgnat/s-parame__ae653.ads, libgnat/s-parame__hpux.ads (Size_Type):
1370 Expand range of type to match the address space of the target.
1371 (Task_Storage_Size): Remove unused type.
1373 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1375 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
1376 of a fixed point type and the parent is a multiplying operation,
1377 resolve the operand with its own type because the context will impose a
1378 resulting type on the result of the multiplication by means of
1379 approriate conversion.
1381 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1383 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
1384 the in-place initialization aggregate created for pragmas
1385 Initialize_Scalars or Normalize_Scalars is performed with checks
1388 2018-05-25 Arnaud Charlet <charlet@adacore.com>
1390 * exp_aggr.adb (Convert_To_Positional): Bump default for
1391 Max_Others_Replicate to 32. Update comments.
1392 * osint.ads (Unknown_Attributes): No longer pretend this is a constant.
1393 (No_File_Info_Cache): Initialize separately.
1394 * osint.adb (No_File_Info_Cache): Update initializer.
1396 2018-05-25 Javier Miranda <miranda@adacore.com>
1398 * sem_res.adb (Resolve_Membership_Op): Allow the use of the membership
1399 test when the left operand is a class-wide interface and the right
1400 operand is not a class-wide type.
1401 * exp_ch4.adb (Tagged_Membership): Adding support for interface as the
1404 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1406 * exp_aggr.adb (Flatten): A quantified expression cannot be duplicated
1407 in an others clause to prevent visibility issues with the generated

1412 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1414 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
1415 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
1416 into three distring cases rather than in one loop which attempts to
1417 handle all three cases. This rewrite eliminates an issue where the last
1418 frame of the stack cannot be freed, thus causing the memory range of a
1419 new frame to approach the overflow point of the memory index type.
1420 Since the overflow is logically treated as a
1421 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
1422 (SS_Allocate_Static): New routine. The routine factorizes the static
1423 secondary stack-related code from the former SS_Allocate.
1425 2018-05-25 Sergey Rybin <rybin@adacore.com>
1427 * doc/gnat_ugn/gnat_and_program_execution.rst: Add description of '-U'
1428 option for gnatelim.
1430 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1432 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
1433 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
1434 is created when the proper body of the stub is analyzed.
1435 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
1436 is the proper body of a subunit, the cloned body must be inserted in
1437 the declarative list that contains the stub.
1439 2018-05-25 Justin Squirek <squirek@adacore.com>
1441 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
1442 generate code for 6.5(8-10) so that we don't get an assertion error
1443 when dealing with an incomplete return type.
1445 2018-05-25 Arnaud Charlet <charlet@adacore.com>
1447 * pprint.adb (Expression_Name): Strip too long expressions to avoid
1448 carrying very large strings.
1450 2018-05-25 Patrick Bernardi <bernardi@adacore.com>
1452 * switch-b.adb (Scan_Binder_Switches): binder switch -Q accepts Natural

1474 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1476 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
1477 Validate_Derived_Type_Instance, to verify that all interfaces
1478 implemented by the formal type are also implemented by the actual. The
1479 verification is complicated when an interface of the formal is declared
1480 in a generic unit and the actual is declared in an instance of it.
1481 There is currently no mechanism to relate an interface declared within
1482 a generic to the corresponding interface in an instance, so we must
1483 traverse the list of interfaces of the actual, looking for a name
1484 match, and verifying that that interface is declared in an instance.
1486 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
1488 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra
1489 assertions; replace function versions of Next_Formal/Next_Actual with
1490 their procedural versions (which are more concise).

1526 * gcc-interface/decl.c (gnat_to_gnu_entity): Add new local variable

1528 <E_Enumeration_Type>: Set precision 1 on boolean types with foreign
1530 <E_Enumeration_Subtype>: Likewise for subtypes.
1531 <E_Record_Type>: Force the size of a storage unit on empty classes.
1532 * gcc-interface/utils.c (make_type_from_size) <BOOLEAN_TYPE>: Skip

2720 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
2721 delegate the secondary stack management when there is no suitable
2722 transient context, and the transient scope was intended to manage the

2727 the comment on usage.
2728 (Find_Transient_Context): Change the initinte loop into a while loop.

2960 during initialization. Remove the previous kludgy algorithm which

3032 * doc/gnat_ugn/gnat_utility_programs.rst: Rewrite gnatpp documentation
3033 to match what the Libadalang-based version does.
3034 * doc/gnat_ugn/about_this_guide.rst: Update reference.
3036 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3038 * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
3039 if it contains at least one component declaration employing a function
3040 call returning on the secondary stack.
3042 2018-01-11 Yannick Moy <moy@adacore.com>
3044 * doc/gnat_rm/standard_and_implementation_defined_restrictions.rst:
3045 Update description of restriction SPARK_05 with SPARK 2014.
3046 * gnat_rm.texi: Regenerate.
3048 2018-01-11 Vasiliy Fofanov <fofanov@adacore.com>
3050 * doc/gnat_ugn/gnat_utility_programs.rst: Fix layout.
3052 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3054 * exp_aggr.adb, exp_ch9.adb, exp_util.adb, sem_aggr.adb, sem_ch3.adb,
3055 sem_res.adb, sem_util.adb: Minor reformatting.
3057 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3059 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
3060 has a delayed aspect which must be processed at the point the type is
3061 frozen. This mimics what is done when the predicate is provided by a
3064 2018-01-11 Doug Rupp <rupp@adacore.com>
3066 * init.c (vxworks): Add macro checks for __aarch64__.
3068 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3070 * exp_util.adb (Add_Failure_Expression): New routine.
3071 (Make_Predicate_Check): Reimplement the handling of Predicate_Failure.
3072 * sem_util.adb (Is_Current_Instance): Code cleanup.
3074 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
3076 * libgnat/s-parame*.adb, libgnat/s-parame*.ads: Remove unneeded
3077 Default_Sec_Stack_Size.
3078 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
3079 limit check so that the integer index does not overflow. Check the
3080 dynamic stack allocation does not cause the secondary stack pointer to
3082 (SS_Info): Align colons.
3083 (SS_Init): Cover the case when bootstraping with an old compiler that
3084 does not set Default_SS_Size.
3086 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3088 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
3089 legality of an inherited operation that may require overriding, ignore
3090 primitive_wrappers that correspond to explicit operations that override
3091 an interface primitive.
3092 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
3093 operation to which the class-wide expression applies is a protected op.
3094 with a primitive_wrapper, verify that the updated inherited expression
3095 does not contain an internal call to a protected function. This
3096 completes the implementation of AI12-0166.
3098 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3100 * ali.adb: Document the remaining letters available for ALI lines.
3101 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
3102 * ali.ads: Update type With_Record. Field
3103 Implicit_With_From_Instantiation is no longer in use. Add field
3105 * csinfo.adb (CSinfo): Remove the setup for attribute
3106 Implicit_With_From_Instantiation.
3107 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
3108 either implicitly or explicitly withed.
3109 (Is_Implicit_With_Clause): New routine.
3110 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
3111 confusion with the with clause attribute by the same name.
3112 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
3113 * rtsfind.adb (Maybe_Add_With): Code cleanup.
3114 * sem_ch8.adb (Present_System_Aux): Code cleanup.
3115 * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
3117 (Implicit_With_On_Parent): Mark the with clause as generated for a
3119 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
3120 instantiation are no longer marked as Implicit_With_From_Instantiation
3121 because they are already marked as implicit.
3122 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
3123 which marks implicit with clauses as related to an instantiation.
3124 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
3125 (Parent_With): New routine.
3126 (Set_Implicit_With_From_Instantiation): Removed.
3127 (Set_Parent_With): New routine.
3128 * sinfo.ads: Update the documentation of attribute Implicit_With.
3129 Remove attribute Implicit_With_From_Instantiation along with
3130 occurrences in nodes. Add attribute Parent_With along with occurrences
3132 (Implicit_With_From_Instantiation): Removed along with pragma Inline.
3133 (Parent_With): New routine along with pragma Inline.
3134 (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.
3135 (Set_Parent_With): New routine along with pragma Inline.
3137 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3139 * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
3140 entity when the enclosing construct is a body.
3142 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
3144 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
3145 Secondary_Stack_Size handling as a pragma is now generated for the
3146 corresponding aspect instead of an attribute. Pragma expression is
3147 relocated instead of evaluated. Discriminant of the corresponding
3148 record type is referenced rather than the type discriminant.
3149 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
3150 Secondary_Stack_Size rep item checks to only look for the pragma rep.
3151 * sem_ch13.adb (Analyze_One_Aspect): Transform
3152 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
3153 because the attribute does not have visibility on a task type's
3154 discriminants when the type's definition is expanded.
3155 (Analyze_Attribute_Definition_Clause): Remove handling of
3156 Attribute_Secondary_Stack_Size.
3157 * snames.adb-tmpl, snames.ads-tmpl: Remove
3158 Attribute_Secondary_Stack_Size, no longer used.
3160 2018-01-11 Justin Squirek <squirek@adacore.com>
3162 * sem_ch8.adb: Minor comment fix.
3164 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3166 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
3167 individual action because the action may denote a complex expression,
3168 such as a case statement, which in turn may contain additional
3171 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3173 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
3174 analysis on a copy of the expression with a copy of the index variable,
3175 because full expansion will rewrite construct into a loop with the
3176 original loop variable.
3177 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
3178 expression is an iterated component association. Full analysis takes
3179 place when construct is rewritten as a loop.
3180 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
3181 is not safe for in-place assignment.
3182 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
3183 entity with no homonym and no other entity in the scope.
3185 2018-01-11 Justin Squirek <squirek@adacore.com>
3187 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
3188 message to be printed on the pragma argument identifier.
3190 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3192 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
3193 entity of the generated invariant procedure in order to construct a
3194 proper entity chain.
3196 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
3198 * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
3201 2018-01-11 Arnaud Charlet <charlet@adacore.com>
3203 * einfo.ads, einfo.adb (Activation_Record_Component,
3204 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
3205 Allow E_Discriminant.
3207 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
3209 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
3210 for atomic access once the component size is taken into account and
3211 also do it if the component type is Atomic or Volatile_Full_Access.
3213 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
3215 * gnatvsn.ads: Bump copyright year.
3217 2018-01-03 Richard Sandiford <richard.sandiford@linaro.org>
3218 Alan Hayward <alan.hayward@arm.com>
3219 David Sherwood <david.sherwood@arm.com>
3221 * gcc-interface/misc.c (enumerate_modes): Treat GET_MODE_BITSIZE

3225 Alan Hayward <alan.hayward@arm.com>
3226 David Sherwood <david.sherwood@arm.com>

3232 Alan Hayward <alan.hayward@arm.com>
3233 David Sherwood <david.sherwood@arm.com>
3235 * gcc-interface/utils.c (gnat_types_compatible_p): Handle
3236 polynomial TYPE_VECTOR_SUBPARTS.
3238 2018-01-03 Richard Sandiford <richard.sandiford@linaro.org>
3239 Alan Hayward <alan.hayward@arm.com>
3240 David Sherwood <david.sherwood@arm.com>
3242 * gcc-interface/misc.c (enumerate_modes): Handle polynomial
3245 2018-01-03 Jakub Jelinek <jakub@redhat.com>
3247 Update copyright years.
3249 * gnat_ugn.texi: Bump @copying's copyright year.
3250 * gnat_rm.texi: Likewise.
