742 comment about the memset case.
744 2018-05-30 Bob Duff <duff@adacore.com>
746 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
747 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
748 We need to analyze it as part of analyzing the block, so that if the
749 call to Element that initializes Elmt_Decl returns on the secondary
750 stack, the block will ss_mark/ss_release. This block is inside the
751 loop; we don't want to leak memory until the loop exits. The purpose
752 of analyzing Elmt_Decl first was to catch the error of modifying it,
753 which is illegal because it's a loop parameter. The above causes us to
754 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
755 it on the Element entity, so we end up with an E_Variable node with the
757 * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.
758 * sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop
759 parameter not allowed" error if Is_Loop_Parameter.
760 * sem_util.adb (Is_Variable): Return False if Is_Loop_Parameter, to
761 trigger the call to Diagnose_Non_Variable_Lhs.

765 * checks.adb (Apply_Scalar_Range_Check):
766 * sem_eval.adb (Check_Non_Static_Context, Out_Of_Range): Ignore out of

775 2018-05-30 Ed Schonberg <schonberg@adacore.com>
777 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
778 a package body that is a compilation unit may contain blocks that
779 declare local subprograms. In Subprogram_Unnesting Mode such
780 subprograms must be handled as nested inside the (implicit) elaboration
781 procedure that executes that statement part. To handle properly uplevel
782 references we construct that subprogram explicitly, to contain blocks
783 and inner subprograms, The statement part of the compilation unit
784 becomes a call to this subprogram. This is only done if blocks are
785 present in the statement list of the body.
787 2018-05-30 Bob Duff <duff@adacore.com>

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

1058 * lib-writ.adb (Write_ALI): Cleanup: avoid use of global var; call new
1060 * libgnat/s-casuti.ads, libgnat/s-casuti.adb (To_Upper, To_Lower,
1061 To_Mixed): New functions.
1062 * osint.adb: Cleanup: use Is_Directory_Separator, which correctly
1063 allows both '\' and '/' on Windows.
1065 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
1067 * repinfo.ads: Minor fixes and tweaks in comments.

1091 * exp_unst.adb (Visit_Node): For indexed components and attribute
1092 references, examine index expressions or associated expressions as well
1093 to record uplevel references.
1094 (Vist_Node): For function and procedure calls, if a formal is an
1095 unconstrained array and the actual is constrained, check whether bounds
1096 of actual have uplevel references.
1098 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1100 * einfo.ads, einfo.adb: Exceptions can be uplevel references, and thus
1101 they can appear as components of activation records.

1107 * exp_ch4.adb (Expand_Composite_Equality): Compute whether the size
1108 depends on a discriminant manually instead of using the predicate
1109 Size_Depends_On_Discriminant in the array type case.
1111 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1113 * exp_unst.adb (Check_Static_Type): For a record subtype, check
1114 discriminant constraints as well.
1115 (Visit_Node): For a selected component, check type of prefix, as is
1116 done for indexed components and slices.
1118 2018-05-28 Javier Miranda <miranda@adacore.com>
1120 * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
1121 value when converting a float value to a fixed-point value. This is
1122 required for CCG because it handles fixed-point types by means of
1123 unsigned integer type variables. The range check is now performed using
1124 the integer value stored in this temporary.
1126 2018-05-28 Yannick Moy <moy@adacore.com>
1128 * sem_util.adb (Is_OK_Volatile_Context): Add attributes First, Last and

1139 (Inherited_Subprograms): Instance of Generic_Inherited_Subprograms with
1140 Sem_Disp.Find_Dispatching_Type.
1141 (Is_Overriding_Subprogram): Instance of
1142 Generic_Is_Overriding_Subprogram with Sem_Disp.Find_Dispatching_Type.
1143 (Inheritance_Utilities_Inst): Instance of Inheritance_Utilities
1144 with Sem_Disp.Find_Dispatching_Type.
1146 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
1148 * exp_ch4.adb (Expand_Composite_Equality): For a composite (or FP)
1149 component type, do not expand array equality using the unconstrained
1150 base type, except for the case where the bounds of the type depend on a
1153 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1155 * einfo.ads, einfo.adb (Needs_Activation_Record): New flag on
1156 access-to-subprogram types, to indicate that an indirect call through
1157 such a type requires an activation record when compiling for LLVM.
1158 * sem_ch3.adb (Access_Subprogram_Declaration): Set new flag as needed.
1160 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1162 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
1163 when bounds of fixed type are static, to remove some spuerfluous
1164 implicit conversions and provide an accurate result when converting
1165 back and forth between the fixed point type and a floating point type.
1167 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1169 * exp_unst.adb (Unnest_Subprogram): Prevent creation of empty
1172 2018-05-28 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
1174 * exp_unst.adb (Check_Static_Type): Add argument to indicate node to be
1175 replaced, if any; all callers changed.
1176 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
1177 constant with private view so we take the address of that entity.
1178 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
1179 any; all callers changed. Handle N_Indexed_Component like
1180 N_Attribute_Reference. Add N_Type_Conversion case.
1181 (Visit_Node): Indexed references can be uplevel if the type isn't
1183 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
1184 been relocated, set first_named pointer in original node as well.
1186 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1188 * exp_aggr.adb (Flatten): Copy tree of expression in a component
1189 association with a range or a set of discrete choices, rather than
1190 relocating the node. This avoids inconsistencies in the tree when
1191 handling nested subprograms with uplevel references for LLVM.

1195 * exp_util.adb (Possible_Bit_Aligned_Component): Always return False in

1204 * libgnat/a-convec.adb (Query_Element): Minor cleanup: remove an
1205 unnecessary use of 'Unrestricted_Access.
1207 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
1209 * repinfo.adb (Expr_Value_S): New routine.
1210 (List_Linker_Section): Properly extract the value of the section
1213 2018-05-28 Patrick Bernardi <bernardi@adacore.com>
1215 * doc/gnat_ugn/building_executable_programs_with_gnat.rst: Update the
1216 description of the -D binder switch to reflect current usage.
1217 * gnat_ugn.texi: Regenerate.
1219 2018-05-28 Gary Dismukes <dismukes@adacore.com>

1244 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
1246 * sem_prag.adb (Process_Atomic_Independent_Shared_Volatile): Include
1247 the declarations of single concurrent types because they fall in the
1248 category of full type and object declarations.
1250 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
1252 * repinfo.adb (Compute_Max_Length): Skip _Parent component.

1255 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1257 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
1258 includes a call to function to which it applies. This may mean an
1259 omission of an attribute reference 'Result, in particular if the
1260 function is pqrameterless.
1262 2018-05-28 Justin Squirek <squirek@adacore.com>
1264 * sem_ch8.adb (Find_Expanded_Name): Add extra guard to make sure the
1265 misresolved package name is not a case of mistaken identity.
1267 2018-05-28 Yannick Moy <moy@adacore.com>
1269 * sem_res.adb (Resolve_Range): Re-resolve the low bound of a range in
1270 GNATprove mode, as the order of resolution (low then high) means that

1274 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
1276 * repinfo.adb (List_Array_Info): Start with an explicit blank line and
1277 end with the linker section, if any.
1278 (List_Entities): Do not output the linker section for record types,
1279 array types and variables.
1280 (Print_Expr): Factor out common processing for unary operators and
1281 special values. Adjust and reorder the various cases.
1282 (List_Object_Info): End with the linker section, if any.
1283 (List_Record_Info): Likewise.
1284 (List_Type_Info): Do not start with a blank line.
1286 2018-05-25 Nicolas Roche <roche@adacore.com>
1288 * libgnat/s-valrea.adb (Scan_Real): Abort computation once it is sure
1289 that the result will be either -infinite or +infinite.
1291 2018-05-25 Patrick Bernardi <bernardi@adacore.com>
1293 * libgnat/s-parame.ads, libgnat/s-parame__vxworks.ads,

1296 (Task_Storage_Size): Remove unused type.
1298 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1300 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
1301 of a fixed point type and the parent is a multiplying operation,
1302 resolve the operand with its own type because the context will impose a
1303 resulting type on the result of the multiplication by means of
1304 approriate conversion.
1306 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1308 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
1309 the in-place initialization aggregate created for pragmas
1310 Initialize_Scalars or Normalize_Scalars is performed with checks
1313 2018-05-25 Arnaud Charlet <charlet@adacore.com>
1315 * exp_aggr.adb (Convert_To_Positional): Bump default for
1316 Max_Others_Replicate to 32. Update comments.
1317 * osint.ads (Unknown_Attributes): No longer pretend this is a constant.
1318 (No_File_Info_Cache): Initialize separately.

1323 * sem_res.adb (Resolve_Membership_Op): Allow the use of the membership
1324 test when the left operand is a class-wide interface and the right
1325 operand is not a class-wide type.
1326 * exp_ch4.adb (Tagged_Membership): Adding support for interface as the
1329 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1331 * exp_aggr.adb (Flatten): A quantified expression cannot be duplicated
1332 in an others clause to prevent visibility issues with the generated
1334 (Component_OK_For_Backend): Return false for a quantified expression.
1335 (Check_Static_Component): Ditto.
1337 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1339 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
1340 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
1341 into three distring cases rather than in one loop which attempts to
1342 handle all three cases. This rewrite eliminates an issue where the last
1343 frame of the stack cannot be freed, thus causing the memory range of a
1344 new frame to approach the overflow point of the memory index type.
1345 Since the overflow is logically treated as a
1346 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
1347 (SS_Allocate_Static): New routine. The routine factorizes the static
1348 secondary stack-related code from the former SS_Allocate.
1350 2018-05-25 Sergey Rybin <rybin@adacore.com>
1352 * doc/gnat_ugn/gnat_and_program_execution.rst: Add description of '-U'
1353 option for gnatelim.
1355 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1357 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
1358 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
1359 is created when the proper body of the stub is analyzed.
1360 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
1361 is the proper body of a subunit, the cloned body must be inserted in
1362 the declarative list that contains the stub.
1364 2018-05-25 Justin Squirek <squirek@adacore.com>
1366 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
1367 generate code for 6.5(8-10) so that we don't get an assertion error
1368 when dealing with an incomplete return type.
1370 2018-05-25 Arnaud Charlet <charlet@adacore.com>
1372 * pprint.adb (Expression_Name): Strip too long expressions to avoid
1373 carrying very large strings.

1377 * switch-b.adb (Scan_Binder_Switches): binder switch -Q accepts Natural

1399 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1401 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
1402 Validate_Derived_Type_Instance, to verify that all interfaces
1403 implemented by the formal type are also implemented by the actual. The
1404 verification is complicated when an interface of the formal is declared
1405 in a generic unit and the actual is declared in an instance of it.
1406 There is currently no mechanism to relate an interface declared within
1407 a generic to the corresponding interface in an instance, so we must
1408 traverse the list of interfaces of the actual, looking for a name
1409 match, and verifying that that interface is declared in an instance.
1411 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
1413 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra
1414 assertions; replace function versions of Next_Formal/Next_Actual with
1415 their procedural versions (which are more concise).

1427 Relative_Timed_Wait.

1449 boolean type with convention C.
1450 * libgnat/i-cexten.ads (bool): Change to boolean with convention C.
1451 * gcc-interface/decl.c (gnat_to_gnu_entity): Add new local variable
1452 FOREIGN and use it throughout the function.
1453 <E_Enumeration_Type>: Set precision 1 on boolean types with foreign
1455 <E_Enumeration_Subtype>: Likewise for subtypes.
1456 <E_Record_Type>: Force the size of a storage unit on empty classes.
1457 * gcc-interface/utils.c (make_type_from_size) <BOOLEAN_TYPE>: Skip
1458 boolean types with precision 1 if the size is the expected one.

1476 prefixes of array attributes, to prefixes that are entity names whose
1477 type is constrained.
1478 (Note_Uplevel_Bound): Verify that the bound is declared in an enclosing
1479 subprogram, as itype created for loops in pre/postcondition may appear
1480 in loops at the library level.
1482 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1484 * sem_ch13.adb (Build_Predicate_Functions): The predicate function
1485 declaration is inserted into the tree and analyzed at that point, so
1486 should not be reinserted when the body is constructed. Inside a
1487 generic, ensure that the body is not inserted twice in the tree.

2521 (Unit_Entity): New routine.
2522 * sem_prag.adb (Analyze_Pragma): Reimplement the handling of pragma
2523 Elaboration_Checks. The analysis now ensures that the pragma appears at
2524 the configuration level, and on the initial declaration of a unit.
2525 Other placements are either flagged as illegal, or ignored.
2526 (Check_Duplicate_Elaboration_Checks_Pragma): New routine.
2527 (Ignore_Elaboration_Checks_Pragma): New routine.

2534 2018-05-21 Olivier Hainque <hainque@adacore.com>
2536 * libgnat/s-trasym__dwarf.adb (Executable_Name): Return argv[0] instead
2537 of empty string when argv[0] couldn't be found on PATH.
2538 (Enable_Cache): Raise Program_Error instead of attempting a null
2539 pointer dereference when the Exec_Module initialization failed.

2558 * sem_util.adb (Find_Simple_Properties): New routine.
2559 (Is_Enabled_External_Property): New routine.
2560 (State_Has_Enabled_Property): Reimplemented. The two flavors of option
2561 External have precedence over option Synchronous when determining
2562 whether a property is in effect.
2564 2018-05-21 Yannick Moy <moy@adacore.com>
2566 * sem_eval.adb (Static_Length): Take into account case of variable of

2581 * libgnat/s-dwalin.ads (Dwarf_Context): Change type of Load_Address to
2582 Address, and type of Low, High to Storage_Offset.
2583 (Low): Rename as Low_Address and convey that the return value is a
2584 runtime reference accounting for a load address.
2585 * libgnat/s-dwalin.adb (Read_Aranges_Entry): Adjust to the
2586 address/offset type changes.
2587 (Aranges_Lookup): Likewise.

2612 lm.l_addr as the Load_Address to Add_Module_To_Cache.
2614 2018-05-21 Piotr Trojanek <trojanek@adacore.com>
2616 * einfo.adb (Has_Discriminants): Stronger assertion.

2639 * sem_attr.adb (Analyze_Attribute, case Scalar_Storage_Order): The
2640 attribute reference is legal within a generic unit when the prefix is a
2641 formal private type.
2643 2018-05-21 Hristian Kirtchev <kirtchev@adacore.com>
2645 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
2646 delegate the secondary stack management when there is no suitable
2647 transient context, and the transient scope was intended to manage the
2648 secondary stack because this causes premature reclamation. Change the
2649 transient scope creation logic by special casing assignment statements
2650 of controlled components for type initialization procedures.
2651 (Find_Node_To_Be_Wrapped): Renamed to Find_Transient_Context. Update
2652 the comment on usage.
2653 (Find_Transient_Context): Change the initinte loop into a while loop.
2654 Iterations schemes and iterator specifications are not valid transient
2655 contexts because they rely on special processing. Assignment statements
2656 are now treated as a normal transient context, special cases are
2657 handled by the caller. Add special processing for pragma Check.
2658 (Is_OK_Construct): Removed. Its functionality has been merged in
2659 routine Find_Transient_Context.
2660 * sem_ch5.adb (Check_Call): Reimplemented. Add code to properly
2661 retrieve the subprogram being invoked. Use a more accurate predicate
2662 (Requires_Transient_Scope) to determine that the function will emply
2663 the secondary stack.

2865 suitable construct to wrap, and the transient scope was intended to
2866 manage the secondary stack.
2867 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
2868 is a valid boundary for a transient expression which comes from the
2869 statements of the alternative, otherwise alternatives cannot be

2871 actions suppressed now stop the traversal as there is no point in
2872 looking for an enclosing construct. Add several N_xxx_Body choices to
2873 the termination conditions for completeness.

2880 (Resolve_Actuals): Account for additional cases where finalization
2881 actions are required by utilizing predicate Needs_Finalization rather
2883 (Resolve_Call): Type initialization procedures can now utilize
2884 transient scopes to manage the secondary stack, thus preventing leaks
2885 during initialization. Remove the previous kludgy algorithm which
2886 attempts to manage the secondary stack at the object creation site.

3026 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
3027 * ali.ads: Update type With_Record. Field
3028 Implicit_With_From_Instantiation is no longer in use. Add field
3030 * csinfo.adb (CSinfo): Remove the setup for attribute
3031 Implicit_With_From_Instantiation.
3032 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
3033 either implicitly or explicitly withed.
3034 (Is_Implicit_With_Clause): New routine.
3035 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
3036 confusion with the with clause attribute by the same name.
3037 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
3038 * rtsfind.adb (Maybe_Add_With): Code cleanup.
3039 * sem_ch8.adb (Present_System_Aux): Code cleanup.
3040 * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
3042 (Implicit_With_On_Parent): Mark the with clause as generated for a
3044 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
3045 instantiation are no longer marked as Implicit_With_From_Instantiation
3046 because they are already marked as implicit.
3047 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
3048 which marks implicit with clauses as related to an instantiation.
3049 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
3050 (Parent_With): New routine.
3051 (Set_Implicit_With_From_Instantiation): Removed.
3052 (Set_Parent_With): New routine.
3053 * sinfo.ads: Update the documentation of attribute Implicit_With.
3054 Remove attribute Implicit_With_From_Instantiation along with
3055 occurrences in nodes. Add attribute Parent_With along with occurrences
3057 (Implicit_With_From_Instantiation): Removed along with pragma Inline.
3058 (Parent_With): New routine along with pragma Inline.
3059 (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.
3060 (Set_Parent_With): New routine along with pragma Inline.
3062 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3064 * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
3065 entity when the enclosing construct is a body.
3067 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
3069 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
3070 Secondary_Stack_Size handling as a pragma is now generated for the
3071 corresponding aspect instead of an attribute. Pragma expression is
3072 relocated instead of evaluated. Discriminant of the corresponding
3073 record type is referenced rather than the type discriminant.
3074 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
3075 Secondary_Stack_Size rep item checks to only look for the pragma rep.
3076 * sem_ch13.adb (Analyze_One_Aspect): Transform
3077 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
3078 because the attribute does not have visibility on a task type's
3079 discriminants when the type's definition is expanded.
3080 (Analyze_Attribute_Definition_Clause): Remove handling of
3081 Attribute_Secondary_Stack_Size.
3082 * snames.adb-tmpl, snames.ads-tmpl: Remove
3083 Attribute_Secondary_Stack_Size, no longer used.

3087 * sem_ch8.adb: Minor comment fix.
3089 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3091 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
3092 individual action because the action may denote a complex expression,
3093 such as a case statement, which in turn may contain additional
3096 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3098 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
3099 analysis on a copy of the expression with a copy of the index variable,
3100 because full expansion will rewrite construct into a loop with the
3101 original loop variable.
3102 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
3103 expression is an iterated component association. Full analysis takes
3104 place when construct is rewritten as a loop.
3105 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
3106 is not safe for in-place assignment.
3107 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
3108 entity with no homonym and no other entity in the scope.
3110 2018-01-11 Justin Squirek <squirek@adacore.com>
3112 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
3113 message to be printed on the pragma argument identifier.
3115 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3117 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
3118 entity of the generated invariant procedure in order to construct a
3119 proper entity chain.
3121 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
3123 * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
3126 2018-01-11 Arnaud Charlet <charlet@adacore.com>
3128 * einfo.ads, einfo.adb (Activation_Record_Component,
3129 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
3130 Allow E_Discriminant.
3132 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
3134 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
3135 for atomic access once the component size is taken into account and
3136 also do it if the component type is Atomic or Volatile_Full_Access.
3138 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
3140 * gnatvsn.ads: Bump copyright year.

3143 Alan Hayward <alan.hayward@arm.com>
3144 David Sherwood <david.sherwood@arm.com>
3146 * gcc-interface/misc.c (enumerate_modes): Treat GET_MODE_BITSIZE

3157 Alan Hayward <alan.hayward@arm.com>
3158 David Sherwood <david.sherwood@arm.com>
3160 * gcc-interface/utils.c (gnat_types_compatible_p): Handle
3161 polynomial TYPE_VECTOR_SUBPARTS.
