530 2018-05-31 Ed Schonberg <schonberg@adacore.com>
532 * exp_unst.ads, exp_unst.adb (In_Synchronized_Unit): New predicate to
533 mark subprograms that cannot be eliminated because they must be treated
534 as reachable from outside the current unit. This includes entry bodies
535 and protected operations.
537 2018-05-31 Ed Schonberg <schonberg@adacore.com>
539 * exp_ch4.adb (Expand_Modular_Addition, Expand_Modular_Subtraction):
540 Convert all operands of the generated code to Standard.Unsigned, to
541 prevent spurious visibility errors. This is needed when the generated
542 expansion involves a modular index type of an array type, and the index
543 type is not immediately visible.

553 if the local raise statement includes a string expression. This
554 expression might be picked up by an outer handler or discarded, but
555 plays no role in this transformation.
557 2018-05-30 Hristian Kirtchev <kirtchev@adacore.com>

565 field in relevant nodes: Allocate, Free, and return statements.
567 2018-05-30 Ed Schonberg <schonberg@adacore.com>
569 * exp_unst.adb (Visit_Node): Do not traverse a Component_Association
570 that has not been analyzed, as will be the case for a nested aggregate
571 that is expanded into individual assignments.

580 set it to use the same processing as Pragma_Max_Queue_Length.
581 * snames.ads-tmpl: Move definition of Name_Max_Entry_Queue_Depth so

583 add an entry for the pragma itself.
585 2018-05-30 Ed Schonberg <schonberg@adacore.com>
587 * freeze.adb (Freeze_Object_Declaration): A pragma Thread_Local_Storage
588 is now legal on a variable of composite type initialized with an
589 aggregate that is fully static and requires no elaboration code.
590 * exp_aggr.adb (Convert_To_Positional): Recognize additional cases of
591 nested aggregates that are compile-time static, so they can be used to
592 initialize variables declared with Threqd_Local_Storage.

606 (Start_Search): Modify to use Start_Search_Internal
607 (Start_Search_Internal): Add to break out an extra flag for searching
608 case insensative due to the potential for directories within the same
609 OS to allow different casing schemes.
610 * sysdep.c (__gnat_name_case_equivalence): Add as a default fallback
611 for when the more precise solution fails.

667 2018-05-30 Ed Schonberg <schonberg@adacore.com>
669 * sem_ch3.adb (Access_Subprogram_Declaration): The flag
670 Needs_Activation_Record is only needed on a subprogram type, not on a

673 component type are anonymous access to subprograms, use the component
674 type to obtain the proper value of Needs_Activation_Record flag for the

679 * gcc-interface/trans.c (gnat_to_gnu) <N_Assignment_Statement>: Add
680 comment about the memset case.
682 2018-05-30 Bob Duff <duff@adacore.com>
684 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
685 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
686 We need to analyze it as part of analyzing the block, so that if the
687 call to Element that initializes Elmt_Decl returns on the secondary
688 stack, the block will ss_mark/ss_release. This block is inside the
689 loop; we don't want to leak memory until the loop exits. The purpose
690 of analyzing Elmt_Decl first was to catch the error of modifying it,
691 which is illegal because it's a loop parameter. The above causes us to
692 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
693 it on the Element entity, so we end up with an E_Variable node with the
695 * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.
696 * sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop
697 parameter not allowed" error if Is_Loop_Parameter.
698 * sem_util.adb (Is_Variable): Return False if Is_Loop_Parameter, to
699 trigger the call to Diagnose_Non_Variable_Lhs.
701 2018-05-30 Arnaud Charlet <charlet@adacore.com>
703 * checks.adb (Apply_Scalar_Range_Check):
704 * sem_eval.adb (Check_Non_Static_Context, Out_Of_Range): Ignore out of
705 range values for System.Priority in CodePeer mode since the actual
706 target compiler may provide a wider range.
708 2018-05-30 Ed Schonberg <schonberg@adacore.com>
710 * exp_unst.adb: Search specification of main unit as well, for
713 2018-05-30 Ed Schonberg <schonberg@adacore.com>
715 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
716 a package body that is a compilation unit may contain blocks that
717 declare local subprograms. In Subprogram_Unnesting Mode such
718 subprograms must be handled as nested inside the (implicit) elaboration
719 procedure that executes that statement part. To handle properly uplevel
720 references we construct that subprogram explicitly, to contain blocks
721 and inner subprograms, The statement part of the compilation unit
722 becomes a call to this subprogram. This is only done if blocks are
723 present in the statement list of the body.
725 2018-05-30 Bob Duff <duff@adacore.com>
727 * exp_ch7.adb: Minor comment fix.
729 2018-05-30 Ed Schonberg <schonberg@adacore.com>

732 that have no corresponding body and appear as attributes of the
733 corresponding wrapper package declaration.
734 (Register_Subprogram): New subprogram, used for subprogram bodies and
735 for subprogram instantiations to enter callable entity into Subp table.

740 * libgnat/s-secsta.ads: Update the documentation of all routines in the
741 public part of the package. Reimplement the private part of the
742 package to account for the new secondary stack structure. Add types
743 and subprograms for testing purposes. Add several documentation

794 tagged type. In such case, collecting the list of primitives we may
795 find two equality primitives: one associated with the untagged private

1034 of actual have uplevel references.
1036 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1038 * einfo.ads, einfo.adb: Exceptions can be uplevel references, and thus
1039 they can appear as components of activation records.
1040 * exp_unst.adb (Visit_Node): A reference to an exception may be an

1045 * exp_ch4.adb (Expand_Composite_Equality): Compute whether the size
1046 depends on a discriminant manually instead of using the predicate
1047 Size_Depends_On_Discriminant in the array type case.
1049 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1051 * exp_unst.adb (Check_Static_Type): For a record subtype, check
1052 discriminant constraints as well.
1053 (Visit_Node): For a selected component, check type of prefix, as is
1054 done for indexed components and slices.
1056 2018-05-28 Javier Miranda <miranda@adacore.com>
1058 * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
1059 value when converting a float value to a fixed-point value. This is
1060 required for CCG because it handles fixed-point types by means of
1061 unsigned integer type variables. The range check is now performed using
1062 the integer value stored in this temporary.
1064 2018-05-28 Yannick Moy <moy@adacore.com>
1066 * sem_util.adb (Is_OK_Volatile_Context): Add attributes First, Last and

1076 Is_Overriding_Subprogram, generic in Find_Dispatching_Type function.
1077 (Inherited_Subprograms): Instance of Generic_Inherited_Subprograms with
1078 Sem_Disp.Find_Dispatching_Type.
1079 (Is_Overriding_Subprogram): Instance of
1080 Generic_Is_Overriding_Subprogram with Sem_Disp.Find_Dispatching_Type.
1081 (Inheritance_Utilities_Inst): Instance of Inheritance_Utilities
1082 with Sem_Disp.Find_Dispatching_Type.
1084 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
1086 * exp_ch4.adb (Expand_Composite_Equality): For a composite (or FP)
1087 component type, do not expand array equality using the unconstrained
1088 base type, except for the case where the bounds of the type depend on a
1091 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1093 * einfo.ads, einfo.adb (Needs_Activation_Record): New flag on
1094 access-to-subprogram types, to indicate that an indirect call through
1095 such a type requires an activation record when compiling for LLVM.
1096 * sem_ch3.adb (Access_Subprogram_Declaration): Set new flag as needed.
1098 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1100 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
1101 when bounds of fixed type are static, to remove some spuerfluous
1102 implicit conversions and provide an accurate result when converting
1103 back and forth between the fixed point type and a floating point type.
1105 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1107 * exp_unst.adb (Unnest_Subprogram): Prevent creation of empty
1110 2018-05-28 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
1112 * exp_unst.adb (Check_Static_Type): Add argument to indicate node to be
1113 replaced, if any; all callers changed.
1114 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
1115 constant with private view so we take the address of that entity.
1116 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
1117 any; all callers changed. Handle N_Indexed_Component like
1118 N_Attribute_Reference. Add N_Type_Conversion case.
1119 (Visit_Node): Indexed references can be uplevel if the type isn't
1121 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
1122 been relocated, set first_named pointer in original node as well.
1124 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1126 * exp_aggr.adb (Flatten): Copy tree of expression in a component
1127 association with a range or a set of discrete choices, rather than
1128 relocating the node. This avoids inconsistencies in the tree when
1129 handling nested subprograms with uplevel references for LLVM.
1131 2018-05-28 Arnaud Charlet <charlet@adacore.com>
1133 * exp_util.adb (Possible_Bit_Aligned_Component): Always return False in

1140 2018-05-28 Bob Duff <duff@adacore.com>
1142 * libgnat/a-convec.adb (Query_Element): Minor cleanup: remove an
1143 unnecessary use of 'Unrestricted_Access.
1145 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
1147 * repinfo.adb (Expr_Value_S): New routine.
1148 (List_Linker_Section): Properly extract the value of the section
1151 2018-05-28 Patrick Bernardi <bernardi@adacore.com>
1153 * doc/gnat_ugn/building_executable_programs_with_gnat.rst: Update the
1154 description of the -D binder switch to reflect current usage.
1155 * gnat_ugn.texi: Regenerate.
1157 2018-05-28 Gary Dismukes <dismukes@adacore.com>
1159 * exp_ch3.adb: Minor reformatting

1182 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
1184 * sem_prag.adb (Process_Atomic_Independent_Shared_Volatile): Include
1185 the declarations of single concurrent types because they fall in the
1186 category of full type and object declarations.
1188 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
1190 * repinfo.adb (Compute_Max_Length): Skip _Parent component.

1193 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1195 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
1196 includes a call to function to which it applies. This may mean an
1197 omission of an attribute reference 'Result, in particular if the
1198 function is pqrameterless.
1200 2018-05-28 Justin Squirek <squirek@adacore.com>
1202 * sem_ch8.adb (Find_Expanded_Name): Add extra guard to make sure the
1203 misresolved package name is not a case of mistaken identity.
1205 2018-05-28 Yannick Moy <moy@adacore.com>
1207 * sem_res.adb (Resolve_Range): Re-resolve the low bound of a range in
1208 GNATprove mode, as the order of resolution (low then high) means that
1209 all the information is not available when resolving the low bound the
1212 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
1214 * repinfo.adb (List_Array_Info): Start with an explicit blank line and
1215 end with the linker section, if any.
1216 (List_Entities): Do not output the linker section for record types,
1217 array types and variables.
1218 (Print_Expr): Factor out common processing for unary operators and
1219 special values. Adjust and reorder the various cases.
1220 (List_Object_Info): End with the linker section, if any.
1221 (List_Record_Info): Likewise.
1222 (List_Type_Info): Do not start with a blank line.
1224 2018-05-25 Nicolas Roche <roche@adacore.com>
1226 * libgnat/s-valrea.adb (Scan_Real): Abort computation once it is sure
1227 that the result will be either -infinite or +infinite.

1234 (Task_Storage_Size): Remove unused type.
1236 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1238 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
1239 of a fixed point type and the parent is a multiplying operation,
1240 resolve the operand with its own type because the context will impose a
1241 resulting type on the result of the multiplication by means of
1242 approriate conversion.
1244 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1246 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
1247 the in-place initialization aggregate created for pragmas
1248 Initialize_Scalars or Normalize_Scalars is performed with checks
1251 2018-05-25 Arnaud Charlet <charlet@adacore.com>
1253 * exp_aggr.adb (Convert_To_Positional): Bump default for
1254 Max_Others_Replicate to 32. Update comments.
1255 * osint.ads (Unknown_Attributes): No longer pretend this is a constant.
1256 (No_File_Info_Cache): Initialize separately.

1261 * sem_res.adb (Resolve_Membership_Op): Allow the use of the membership
1262 test when the left operand is a class-wide interface and the right
1263 operand is not a class-wide type.
1264 * exp_ch4.adb (Tagged_Membership): Adding support for interface as the
1267 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1269 * exp_aggr.adb (Flatten): A quantified expression cannot be duplicated
1270 in an others clause to prevent visibility issues with the generated

1275 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1277 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
1278 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
1279 into three distring cases rather than in one loop which attempts to
1280 handle all three cases. This rewrite eliminates an issue where the last
1281 frame of the stack cannot be freed, thus causing the memory range of a
1282 new frame to approach the overflow point of the memory index type.
1283 Since the overflow is logically treated as a
1284 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
1285 (SS_Allocate_Static): New routine. The routine factorizes the static
1286 secondary stack-related code from the former SS_Allocate.
1288 2018-05-25 Sergey Rybin <rybin@adacore.com>
1290 * doc/gnat_ugn/gnat_and_program_execution.rst: Add description of '-U'
1291 option for gnatelim.
1293 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1295 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
1296 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
1297 is created when the proper body of the stub is analyzed.
1298 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
1299 is the proper body of a subunit, the cloned body must be inserted in
1300 the declarative list that contains the stub.
1302 2018-05-25 Justin Squirek <squirek@adacore.com>
1304 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
1305 generate code for 6.5(8-10) so that we don't get an assertion error
1306 when dealing with an incomplete return type.
1308 2018-05-25 Arnaud Charlet <charlet@adacore.com>
1310 * pprint.adb (Expression_Name): Strip too long expressions to avoid
1311 carrying very large strings.

1337 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1339 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
1340 Validate_Derived_Type_Instance, to verify that all interfaces
1341 implemented by the formal type are also implemented by the actual. The
1342 verification is complicated when an interface of the formal is declared
1343 in a generic unit and the actual is declared in an instance of it.
1344 There is currently no mechanism to relate an interface declared within
1345 a generic to the corresponding interface in an instance, so we must
1346 traverse the list of interfaces of the actual, looking for a name
1347 match, and verifying that that interface is declared in an instance.
1349 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
1351 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra
1352 assertions; replace function versions of Next_Formal/Next_Actual with
1353 their procedural versions (which are more concise).

1387 boolean type with convention C.
1388 * libgnat/i-cexten.ads (bool): Change to boolean with convention C.
1389 * gcc-interface/decl.c (gnat_to_gnu_entity): Add new local variable
1390 FOREIGN and use it throughout the function.
1391 <E_Enumeration_Type>: Set precision 1 on boolean types with foreign
1393 <E_Enumeration_Subtype>: Likewise for subtypes.
1394 <E_Record_Type>: Force the size of a storage unit on empty classes.
1395 * gcc-interface/utils.c (make_type_from_size) <BOOLEAN_TYPE>: Skip
1396 boolean types with precision 1 if the size is the expected one.

1414 prefixes of array attributes, to prefixes that are entity names whose
1415 type is constrained.
1416 (Note_Uplevel_Bound): Verify that the bound is declared in an enclosing
1417 subprogram, as itype created for loops in pre/postcondition may appear
1418 in loops at the library level.
1420 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1422 * sem_ch13.adb (Build_Predicate_Functions): The predicate function
1423 declaration is inserted into the tree and analyzed at that point, so
1424 should not be reinserted when the body is constructed. Inside a
1425 generic, ensure that the body is not inserted twice in the tree.

2519 * libgnat/s-dwalin.ads (Dwarf_Context): Change type of Load_Address to
2520 Address, and type of Low, High to Storage_Offset.
2521 (Low): Rename as Low_Address and convey that the return value is a
2522 runtime reference accounting for a load address.
2523 * libgnat/s-dwalin.adb (Read_Aranges_Entry): Adjust to the
2524 address/offset type changes.
2525 (Aranges_Lookup): Likewise.

2547 * libgnat/s-trasym__dwarf.adb (Add_Module_To_Cache): Expect a
2548 Load_Address argument and pass it down to Init_Module.
2549 * libgnat/s-tsmona__linux.adb (Build_Cache_For_All_Modules): Pass
2550 lm.l_addr as the Load_Address to Add_Module_To_Cache.
2552 2018-05-21 Piotr Trojanek <trojanek@adacore.com>
2554 * einfo.adb (Has_Discriminants): Stronger assertion.

2583 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
2584 delegate the secondary stack management when there is no suitable
2585 transient context, and the transient scope was intended to manage the
2586 secondary stack because this causes premature reclamation. Change the
2587 transient scope creation logic by special casing assignment statements
2588 of controlled components for type initialization procedures.
2589 (Find_Node_To_Be_Wrapped): Renamed to Find_Transient_Context. Update
2590 the comment on usage.
2591 (Find_Transient_Context): Change the initinte loop into a while loop.
2592 Iterations schemes and iterator specifications are not valid transient
2593 contexts because they rely on special processing. Assignment statements
2594 are now treated as a normal transient context, special cases are
2595 handled by the caller. Add special processing for pragma Check.
2596 (Is_OK_Construct): Removed. Its functionality has been merged in
2597 routine Find_Transient_Context.
2598 * sem_ch5.adb (Check_Call): Reimplemented. Add code to properly
2599 retrieve the subprogram being invoked. Use a more accurate predicate
2600 (Requires_Transient_Scope) to determine that the function will emply
2601 the secondary stack.

2803 suitable construct to wrap, and the transient scope was intended to
2804 manage the secondary stack.
2805 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
2806 is a valid boundary for a transient expression which comes from the
2807 statements of the alternative, otherwise alternatives cannot be
2808 wrapped. Assignments of controlled objects which have controlled
2809 actions suppressed now stop the traversal as there is no point in
2810 looking for an enclosing construct. Add several N_xxx_Body choices to
2811 the termination conditions for completeness.

2818 (Resolve_Actuals): Account for additional cases where finalization
2819 actions are required by utilizing predicate Needs_Finalization rather
2821 (Resolve_Call): Type initialization procedures can now utilize
2822 transient scopes to manage the secondary stack, thus preventing leaks
2823 during initialization. Remove the previous kludgy algorithm which
2824 attempts to manage the secondary stack at the object creation site.

3016 because the attribute does not have visibility on a task type's
3017 discriminants when the type's definition is expanded.
3018 (Analyze_Attribute_Definition_Clause): Remove handling of
3019 Attribute_Secondary_Stack_Size.
3020 * snames.adb-tmpl, snames.ads-tmpl: Remove
3021 Attribute_Secondary_Stack_Size, no longer used.

3029 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
3030 individual action because the action may denote a complex expression,
3031 such as a case statement, which in turn may contain additional
3034 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3036 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
3037 analysis on a copy of the expression with a copy of the index variable,
3038 because full expansion will rewrite construct into a loop with the
3039 original loop variable.
3040 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
3041 expression is an iterated component association. Full analysis takes
3042 place when construct is rewritten as a loop.
3043 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
3044 is not safe for in-place assignment.
3045 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
3046 entity with no homonym and no other entity in the scope.
3048 2018-01-11 Justin Squirek <squirek@adacore.com>
3050 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
3051 message to be printed on the pragma argument identifier.
3053 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3055 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
3056 entity of the generated invariant procedure in order to construct a
3057 proper entity chain.

3061 * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
3064 2018-01-11 Arnaud Charlet <charlet@adacore.com>
3066 * einfo.ads, einfo.adb (Activation_Record_Component,
3067 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
3068 Allow E_Discriminant.
3070 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
3072 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
3073 for atomic access once the component size is taken into account and
3074 also do it if the component type is Atomic or Volatile_Full_Access.
3076 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
3078 * gnatvsn.ads: Bump copyright year.
