531 2018-05-31 Ed Schonberg <schonberg@adacore.com>
533 * exp_ch4.adb (Expand_Modular_Addition, Expand_Modular_Subtraction):
534 Convert all operands of the generated code to Standard.Unsigned, to
535 prevent spurious visibility errors. This is needed when the generated
536 expansion involves a modular index type of an array type, and the index
537 type is not immediately visible.

541 * einfo.ads (Package_Instantiation): Update comment after a routine
542 that uses this field has been renamed.
544 2018-05-30 Ed Schonberg <schonberg@adacore.com>
546 * exp_ch11.adb (Replace_Raise_By_Goto): The transfomation is legal even
547 if the local raise statement includes a string expression. This
548 expression might be picked up by an outer handler or discarded, but
549 plays no role in this transformation.
551 2018-05-30 Hristian Kirtchev <kirtchev@adacore.com>
553 * exp_aggr.adb, exp_unst.adb, freeze.adb, libgnat/a-direct.adb: Minor

559 field in relevant nodes: Allocate, Free, and return statements.
561 2018-05-30 Ed Schonberg <schonberg@adacore.com>
563 * exp_unst.adb (Visit_Node): Do not traverse a Component_Association
564 that has not been analyzed, as will be the case for a nested aggregate
565 that is expanded into individual assignments.

574 set it to use the same processing as Pragma_Max_Queue_Length.
575 * snames.ads-tmpl: Move definition of Name_Max_Entry_Queue_Depth so
576 that it can be processed as a pragma in addition to a restriction and
577 add an entry for the pragma itself.
579 2018-05-30 Ed Schonberg <schonberg@adacore.com>

582 is now legal on a variable of composite type initialized with an
583 aggregate that is fully static and requires no elaboration code.
584 * exp_aggr.adb (Convert_To_Positional): Recognize additional cases of
585 nested aggregates that are compile-time static, so they can be used to

600 (Start_Search): Modify to use Start_Search_Internal
601 (Start_Search_Internal): Add to break out an extra flag for searching
602 case insensative due to the potential for directories within the same
603 OS to allow different casing schemes.
604 * sysdep.c (__gnat_name_case_equivalence): Add as a default fallback
605 for when the more precise solution fails.

661 2018-05-30 Ed Schonberg <schonberg@adacore.com>
663 * sem_ch3.adb (Access_Subprogram_Declaration): The flag
664 Needs_Activation_Record is only needed on a subprogram type, not on a

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

673 * gcc-interface/trans.c (gnat_to_gnu) <N_Assignment_Statement>: Add
674 comment about the memset case.
676 2018-05-30 Bob Duff <duff@adacore.com>
678 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
679 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
680 We need to analyze it as part of analyzing the block, so that if the
681 call to Element that initializes Elmt_Decl returns on the secondary
682 stack, the block will ss_mark/ss_release. This block is inside the
683 loop; we don't want to leak memory until the loop exits. The purpose
684 of analyzing Elmt_Decl first was to catch the error of modifying it,
685 which is illegal because it's a loop parameter. The above causes us to
686 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
687 it on the Element entity, so we end up with an E_Variable node with the
689 * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.
690 * sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop
691 parameter not allowed" error if Is_Loop_Parameter.
692 * sem_util.adb (Is_Variable): Return False if Is_Loop_Parameter, to
693 trigger the call to Diagnose_Non_Variable_Lhs.
695 2018-05-30 Arnaud Charlet <charlet@adacore.com>
697 * checks.adb (Apply_Scalar_Range_Check):
698 * sem_eval.adb (Check_Non_Static_Context, Out_Of_Range): Ignore out of
699 range values for System.Priority in CodePeer mode since the actual
700 target compiler may provide a wider range.
702 2018-05-30 Ed Schonberg <schonberg@adacore.com>
704 * exp_unst.adb: Search specification of main unit as well, for
707 2018-05-30 Ed Schonberg <schonberg@adacore.com>
709 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
710 a package body that is a compilation unit may contain blocks that
711 declare local subprograms. In Subprogram_Unnesting Mode such
712 subprograms must be handled as nested inside the (implicit) elaboration
713 procedure that executes that statement part. To handle properly uplevel
714 references we construct that subprogram explicitly, to contain blocks
715 and inner subprograms, The statement part of the compilation unit
716 becomes a call to this subprogram. This is only done if blocks are
717 present in the statement list of the body.
719 2018-05-30 Bob Duff <duff@adacore.com>
721 * exp_ch7.adb: Minor comment fix.
723 2018-05-30 Ed Schonberg <schonberg@adacore.com>

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

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

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

1039 * exp_ch4.adb (Expand_Composite_Equality): Compute whether the size
1040 depends on a discriminant manually instead of using the predicate
1041 Size_Depends_On_Discriminant in the array type case.
1043 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1045 * exp_unst.adb (Check_Static_Type): For a record subtype, check
1046 discriminant constraints as well.
1047 (Visit_Node): For a selected component, check type of prefix, as is
1048 done for indexed components and slices.
1050 2018-05-28 Javier Miranda <miranda@adacore.com>
1052 * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
1053 value when converting a float value to a fixed-point value. This is
1054 required for CCG because it handles fixed-point types by means of
1055 unsigned integer type variables. The range check is now performed using
1056 the integer value stored in this temporary.
1058 2018-05-28 Yannick Moy <moy@adacore.com>
1060 * sem_util.adb (Is_OK_Volatile_Context): Add attributes First, Last and

1070 Is_Overriding_Subprogram, generic in Find_Dispatching_Type function.
1071 (Inherited_Subprograms): Instance of Generic_Inherited_Subprograms with
1072 Sem_Disp.Find_Dispatching_Type.
1073 (Is_Overriding_Subprogram): Instance of
1074 Generic_Is_Overriding_Subprogram with Sem_Disp.Find_Dispatching_Type.
1075 (Inheritance_Utilities_Inst): Instance of Inheritance_Utilities
1076 with Sem_Disp.Find_Dispatching_Type.
1078 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
1080 * exp_ch4.adb (Expand_Composite_Equality): For a composite (or FP)
1081 component type, do not expand array equality using the unconstrained
1082 base type, except for the case where the bounds of the type depend on a
1085 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1087 * einfo.ads, einfo.adb (Needs_Activation_Record): New flag on
1088 access-to-subprogram types, to indicate that an indirect call through
1089 such a type requires an activation record when compiling for LLVM.
1090 * sem_ch3.adb (Access_Subprogram_Declaration): Set new flag as needed.
1092 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1094 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
1095 when bounds of fixed type are static, to remove some spuerfluous
1096 implicit conversions and provide an accurate result when converting
1097 back and forth between the fixed point type and a floating point type.
1099 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1101 * exp_unst.adb (Unnest_Subprogram): Prevent creation of empty
1104 2018-05-28 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
1106 * exp_unst.adb (Check_Static_Type): Add argument to indicate node to be
1107 replaced, if any; all callers changed.
1108 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
1109 constant with private view so we take the address of that entity.
1110 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
1111 any; all callers changed. Handle N_Indexed_Component like
1112 N_Attribute_Reference. Add N_Type_Conversion case.
1113 (Visit_Node): Indexed references can be uplevel if the type isn't
1115 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
1116 been relocated, set first_named pointer in original node as well.
1118 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1120 * exp_aggr.adb (Flatten): Copy tree of expression in a component
1121 association with a range or a set of discrete choices, rather than
1122 relocating the node. This avoids inconsistencies in the tree when
1123 handling nested subprograms with uplevel references for LLVM.
1125 2018-05-28 Arnaud Charlet <charlet@adacore.com>
1127 * exp_util.adb (Possible_Bit_Aligned_Component): Always return False in

1136 * libgnat/a-convec.adb (Query_Element): Minor cleanup: remove an
1137 unnecessary use of 'Unrestricted_Access.
1139 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
1141 * repinfo.adb (Expr_Value_S): New routine.
1142 (List_Linker_Section): Properly extract the value of the section
1145 2018-05-28 Patrick Bernardi <bernardi@adacore.com>
1147 * doc/gnat_ugn/building_executable_programs_with_gnat.rst: Update the
1148 description of the -D binder switch to reflect current usage.
1149 * gnat_ugn.texi: Regenerate.
1151 2018-05-28 Gary Dismukes <dismukes@adacore.com>

1176 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
1178 * sem_prag.adb (Process_Atomic_Independent_Shared_Volatile): Include
1179 the declarations of single concurrent types because they fall in the
1180 category of full type and object declarations.
1182 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
1184 * repinfo.adb (Compute_Max_Length): Skip _Parent component.

1187 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1189 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
1190 includes a call to function to which it applies. This may mean an
1191 omission of an attribute reference 'Result, in particular if the
1192 function is pqrameterless.
1194 2018-05-28 Justin Squirek <squirek@adacore.com>

1201 * sem_res.adb (Resolve_Range): Re-resolve the low bound of a range in
1202 GNATprove mode, as the order of resolution (low then high) means that

1208 * repinfo.adb (List_Array_Info): Start with an explicit blank line and
1209 end with the linker section, if any.
1210 (List_Entities): Do not output the linker section for record types,
1211 array types and variables.
1212 (Print_Expr): Factor out common processing for unary operators and
1213 special values. Adjust and reorder the various cases.
1214 (List_Object_Info): End with the linker section, if any.
1215 (List_Record_Info): Likewise.
1216 (List_Type_Info): Do not start with a blank line.
1218 2018-05-25 Nicolas Roche <roche@adacore.com>
1220 * libgnat/s-valrea.adb (Scan_Real): Abort computation once it is sure
1221 that the result will be either -infinite or +infinite.

1228 (Task_Storage_Size): Remove unused type.
1230 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1232 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
1233 of a fixed point type and the parent is a multiplying operation,
1234 resolve the operand with its own type because the context will impose a
1235 resulting type on the result of the multiplication by means of
1236 approriate conversion.
1238 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1240 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
1241 the in-place initialization aggregate created for pragmas
1242 Initialize_Scalars or Normalize_Scalars is performed with checks
1245 2018-05-25 Arnaud Charlet <charlet@adacore.com>
1247 * exp_aggr.adb (Convert_To_Positional): Bump default for
1248 Max_Others_Replicate to 32. Update comments.
1249 * osint.ads (Unknown_Attributes): No longer pretend this is a constant.
1250 (No_File_Info_Cache): Initialize separately.

1255 * sem_res.adb (Resolve_Membership_Op): Allow the use of the membership
1256 test when the left operand is a class-wide interface and the right
1257 operand is not a class-wide type.

1261 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1263 * exp_aggr.adb (Flatten): A quantified expression cannot be duplicated
1264 in an others clause to prevent visibility issues with the generated

1269 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1271 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
1272 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
1273 into three distring cases rather than in one loop which attempts to
1274 handle all three cases. This rewrite eliminates an issue where the last
1275 frame of the stack cannot be freed, thus causing the memory range of a
1276 new frame to approach the overflow point of the memory index type.
1277 Since the overflow is logically treated as a
1278 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
1279 (SS_Allocate_Static): New routine. The routine factorizes the static
1280 secondary stack-related code from the former SS_Allocate.
1282 2018-05-25 Sergey Rybin <rybin@adacore.com>
1284 * doc/gnat_ugn/gnat_and_program_execution.rst: Add description of '-U'
1285 option for gnatelim.
1287 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1289 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
1290 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
1291 is created when the proper body of the stub is analyzed.
1292 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
1293 is the proper body of a subunit, the cloned body must be inserted in
1294 the declarative list that contains the stub.
1296 2018-05-25 Justin Squirek <squirek@adacore.com>
1298 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
1299 generate code for 6.5(8-10) so that we don't get an assertion error
1300 when dealing with an incomplete return type.
1302 2018-05-25 Arnaud Charlet <charlet@adacore.com>
1304 * pprint.adb (Expression_Name): Strip too long expressions to avoid
1305 carrying very large strings.

1331 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1333 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
1334 Validate_Derived_Type_Instance, to verify that all interfaces
1335 implemented by the formal type are also implemented by the actual. The
1336 verification is complicated when an interface of the formal is declared
1337 in a generic unit and the actual is declared in an instance of it.
1338 There is currently no mechanism to relate an interface declared within
1339 a generic to the corresponding interface in an instance, so we must
1340 traverse the list of interfaces of the actual, looking for a name
1341 match, and verifying that that interface is declared in an instance.
1343 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
1345 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra
1346 assertions; replace function versions of Next_Formal/Next_Actual with
1347 their procedural versions (which are more concise).

1381 boolean type with convention C.
1382 * libgnat/i-cexten.ads (bool): Change to boolean with convention C.
1383 * gcc-interface/decl.c (gnat_to_gnu_entity): Add new local variable
1384 FOREIGN and use it throughout the function.
1385 <E_Enumeration_Type>: Set precision 1 on boolean types with foreign
1387 <E_Enumeration_Subtype>: Likewise for subtypes.
1388 <E_Record_Type>: Force the size of a storage unit on empty classes.
1389 * gcc-interface/utils.c (make_type_from_size) <BOOLEAN_TYPE>: Skip
1390 boolean types with precision 1 if the size is the expected one.

1408 prefixes of array attributes, to prefixes that are entity names whose
1409 type is constrained.
1410 (Note_Uplevel_Bound): Verify that the bound is declared in an enclosing
1411 subprogram, as itype created for loops in pre/postcondition may appear
1412 in loops at the library level.
1414 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1416 * sem_ch13.adb (Build_Predicate_Functions): The predicate function
1417 declaration is inserted into the tree and analyzed at that point, so
1418 should not be reinserted when the body is constructed. Inside a
1419 generic, ensure that the body is not inserted twice in the tree.
1421 2018-05-25 Yannick Moy <moy@adacore.com>

2513 * libgnat/s-dwalin.ads (Dwarf_Context): Change type of Load_Address to
2514 Address, and type of Low, High to Storage_Offset.
2515 (Low): Rename as Low_Address and convey that the return value is a
2516 runtime reference accounting for a load address.
2517 * libgnat/s-dwalin.adb (Read_Aranges_Entry): Adjust to the
2518 address/offset type changes.
2519 (Aranges_Lookup): Likewise.
2520 (Symbolic_Address): Likewise.
2521 (Symbolic_Traceback): Likewise.
2522 (Dump_Cache): Likewise.
2523 (Is_Inside): Likewise.
2525 (Set_Load_Address): Likewise.
2526 (Low_Address): Likewise, and account for C.Load_Address.
2527 * libgnat/s-trasym__dwarf.adb (Lt): Use Low_Address instead of Low.
2528 (Multi_Module_Symbolic_Traceback): Compare address in traceback
2529 with module Low_Address instead of Low.
2531 2018-05-21 Olivier Hainque <hainque@adacore.com>
2533 * libgnat/s-dwalin.ads (Dwarf_Context): Rename Load_Slide as
2535 * libgnat/s-dwalin.adb (Is_Inside): Adjust accordingly.
2536 (Set_Load_Address): Likewise.
2537 (Symbolic_Traceback): Likewise.
2539 2018-05-21 Olivier Hainque <hainque@adacore.com>
2541 * libgnat/s-trasym__dwarf.adb (Add_Module_To_Cache): Expect a
2542 Load_Address argument and pass it down to Init_Module.
2543 * libgnat/s-tsmona__linux.adb (Build_Cache_For_All_Modules): Pass
2544 lm.l_addr as the Load_Address to Add_Module_To_Cache.
2546 2018-05-21 Piotr Trojanek <trojanek@adacore.com>
2548 * einfo.adb (Has_Discriminants): Stronger assertion.
2549 (Set_Has_Discriminants): Stronger assertion.

2554 * sem_ch7.adb (Generate_Parent_References): Prevent calls to
2555 Has_Discriminant on non-type entities that might happen when the
2556 compiled code has errors.

2572 attribute reference is legal within a generic unit when the prefix is a
2573 formal private type.
2575 2018-05-21 Hristian Kirtchev <kirtchev@adacore.com>
2577 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
2578 delegate the secondary stack management when there is no suitable
2579 transient context, and the transient scope was intended to manage the
2580 secondary stack because this causes premature reclamation. Change the
2581 transient scope creation logic by special casing assignment statements
2582 of controlled components for type initialization procedures.
2583 (Find_Node_To_Be_Wrapped): Renamed to Find_Transient_Context. Update
2584 the comment on usage.
2585 (Find_Transient_Context): Change the initinte loop into a while loop.
2586 Iterations schemes and iterator specifications are not valid transient
2587 contexts because they rely on special processing. Assignment statements
2588 are now treated as a normal transient context, special cases are
2589 handled by the caller. Add special processing for pragma Check.
2590 (Is_OK_Construct): Removed. Its functionality has been merged in
2591 routine Find_Transient_Context.
2592 * sem_ch5.adb (Check_Call): Reimplemented. Add code to properly
2593 retrieve the subprogram being invoked. Use a more accurate predicate
2594 (Requires_Transient_Scope) to determine that the function will emply
2595 the secondary stack.

2716 * exp_ch6.adb (Make_Build_In_Place_Call_In_Object_Declaration): Handle
2717 properly object declarations with initializations that are
2718 build-in-place function calls, when there is an address specification,
2719 either as an aspect specification or an explicit attribute
2720 specification clause, for the initialized object.

2739 replicated by Is_Declaration.
2740 * sem_util.ads (Is_Declaration): New parameter profile. Update the

2796 management of the secondary stack to an enclosing scope if there is no
2797 suitable construct to wrap, and the transient scope was intended to
2798 manage the secondary stack.
2799 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
2800 is a valid boundary for a transient expression which comes from the
2801 statements of the alternative, otherwise alternatives cannot be
2802 wrapped. Assignments of controlled objects which have controlled
2803 actions suppressed now stop the traversal as there is no point in
2804 looking for an enclosing construct. Add several N_xxx_Body choices to
2805 the termination conditions for completeness.
2806 * exp_ch7.ads (Establish_Transient_Scope): Update the parameter profile
2807 and the associated comment on usage.
2808 * exp_smem.adb (Add_Shared_Var_Lock_Procs): Update the call to

2812 (Resolve_Actuals): Account for additional cases where finalization
2813 actions are required by utilizing predicate Needs_Finalization rather
2815 (Resolve_Call): Type initialization procedures can now utilize
2816 transient scopes to manage the secondary stack, thus preventing leaks
2817 during initialization. Remove the previous kludgy algorithm which
2818 attempts to manage the secondary stack at the object creation site.

2866 in the generic unless they reference a formal subprogram. Clarify

2950 operation to which the class-wide expression applies is a protected op.
2951 with a primitive_wrapper, verify that the updated inherited expression

2967 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
2968 confusion with the with clause attribute by the same name.

2978 because they are already marked as implicit.

2980 which marks implicit with clauses as related to an instantiation.
2981 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
2982 (Parent_With): New routine.
2983 (Set_Implicit_With_From_Instantiation): Removed.

3001 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
3002 Secondary_Stack_Size handling as a pragma is now generated for the
3003 corresponding aspect instead of an attribute. Pragma expression is
3004 relocated instead of evaluated. Discriminant of the corresponding
3005 record type is referenced rather than the type discriminant.
3006 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
3007 Secondary_Stack_Size rep item checks to only look for the pragma rep.
3008 * sem_ch13.adb (Analyze_One_Aspect): Transform

3023 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
3024 individual action because the action may denote a complex expression,
3025 such as a case statement, which in turn may contain additional

3030 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
3031 analysis on a copy of the expression with a copy of the index variable,
3032 because full expansion will rewrite construct into a loop with the
3033 original loop variable.
3034 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
3035 expression is an iterated component association. Full analysis takes
3036 place when construct is rewritten as a loop.
3037 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
3038 is not safe for in-place assignment.
3039 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
3040 entity with no homonym and no other entity in the scope.

3045 message to be printed on the pragma argument identifier.

3050 entity of the generated invariant procedure in order to construct a
3051 proper entity chain.

3061 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
3062 Allow E_Discriminant.
3064 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
3066 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
3067 for atomic access once the component size is taken into account and
3068 also do it if the component type is Atomic or Volatile_Full_Access.
3070 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
3072 * gnatvsn.ads: Bump copyright year.
