535 2018-05-31 Ed Schonberg <schonberg@adacore.com>
537 * exp_unst.ads, exp_unst.adb (In_Synchronized_Unit): New predicate to
538 mark subprograms that cannot be eliminated because they must be treated

540 and protected operations.
542 2018-05-31 Ed Schonberg <schonberg@adacore.com>
544 * exp_ch4.adb (Expand_Modular_Addition, Expand_Modular_Subtraction):
545 Convert all operands of the generated code to Standard.Unsigned, to
546 prevent spurious visibility errors. This is needed when the generated

558 if the local raise statement includes a string expression. This
559 expression might be picked up by an outer handler or discarded, but
560 plays no role in this transformation.
562 2018-05-30 Hristian Kirtchev <kirtchev@adacore.com>

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

674 * sem_ch3.adb (Access_Subprogram_Declaration): The flag
675 Needs_Activation_Record is only needed on a subprogram type, not on a

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

685 comment about the memset case.
687 2018-05-30 Bob Duff <duff@adacore.com>
689 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
690 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
691 We need to analyze it as part of analyzing the block, so that if the
692 call to Element that initializes Elmt_Decl returns on the secondary
693 stack, the block will ss_mark/ss_release. This block is inside the
694 loop; we don't want to leak memory until the loop exits. The purpose
695 of analyzing Elmt_Decl first was to catch the error of modifying it,
696 which is illegal because it's a loop parameter. The above causes us to
697 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
698 it on the Element entity, so we end up with an E_Variable node with the
700 * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.
701 * sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop
702 parameter not allowed" error if Is_Loop_Parameter.
703 * sem_util.adb (Is_Variable): Return False if Is_Loop_Parameter, to
704 trigger the call to Diagnose_Non_Variable_Lhs.
706 2018-05-30 Arnaud Charlet <charlet@adacore.com>
708 * checks.adb (Apply_Scalar_Range_Check):
709 * sem_eval.adb (Check_Non_Static_Context, Out_Of_Range): Ignore out of
710 range values for System.Priority in CodePeer mode since the actual
711 target compiler may provide a wider range.

715 * exp_unst.adb: Search specification of main unit as well, for
718 2018-05-30 Ed Schonberg <schonberg@adacore.com>
720 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
721 a package body that is a compilation unit may contain blocks that
722 declare local subprograms. In Subprogram_Unnesting Mode such
723 subprograms must be handled as nested inside the (implicit) elaboration
724 procedure that executes that statement part. To handle properly uplevel
725 references we construct that subprogram explicitly, to contain blocks
726 and inner subprograms, The statement part of the compilation unit
727 becomes a call to this subprogram. This is only done if blocks are
728 present in the statement list of the body.
730 2018-05-30 Bob Duff <duff@adacore.com>
732 * exp_ch7.adb: Minor comment fix.

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

746 public part of the package. Reimplement the private part of the
747 package to account for the new secondary stack structure. Add types
748 and subprograms for testing purposes. Add several documentation

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

1034 * exp_unst.adb (Visit_Node): For indexed components and attribute
1035 references, examine index expressions or associated expressions as well
1036 to record uplevel references.
1037 (Vist_Node): For function and procedure calls, if a formal is an
1038 unconstrained array and the actual is constrained, check whether bounds
1039 of actual have uplevel references.
1041 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1043 * einfo.ads, einfo.adb: Exceptions can be uplevel references, and thus
1044 they can appear as components of activation records.
1045 * exp_unst.adb (Visit_Node): A reference to an exception may be an

1050 * exp_ch4.adb (Expand_Composite_Equality): Compute whether the size
1051 depends on a discriminant manually instead of using the predicate
1052 Size_Depends_On_Discriminant in the array type case.
1054 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1056 * exp_unst.adb (Check_Static_Type): For a record subtype, check
1057 discriminant constraints as well.
1058 (Visit_Node): For a selected component, check type of prefix, as is
1059 done for indexed components and slices.
1061 2018-05-28 Javier Miranda <miranda@adacore.com>
1063 * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
1064 value when converting a float value to a fixed-point value. This is
1065 required for CCG because it handles fixed-point types by means of
1066 unsigned integer type variables. The range check is now performed using
1067 the integer value stored in this temporary.
1069 2018-05-28 Yannick Moy <moy@adacore.com>
1071 * sem_util.adb (Is_OK_Volatile_Context): Add attributes First, Last and

1082 (Inherited_Subprograms): Instance of Generic_Inherited_Subprograms with
1083 Sem_Disp.Find_Dispatching_Type.
1084 (Is_Overriding_Subprogram): Instance of
1085 Generic_Is_Overriding_Subprogram with Sem_Disp.Find_Dispatching_Type.
1086 (Inheritance_Utilities_Inst): Instance of Inheritance_Utilities
1087 with Sem_Disp.Find_Dispatching_Type.
1089 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
1091 * exp_ch4.adb (Expand_Composite_Equality): For a composite (or FP)
1092 component type, do not expand array equality using the unconstrained
1093 base type, except for the case where the bounds of the type depend on a
1096 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1098 * einfo.ads, einfo.adb (Needs_Activation_Record): New flag on
1099 access-to-subprogram types, to indicate that an indirect call through
1100 such a type requires an activation record when compiling for LLVM.
1101 * sem_ch3.adb (Access_Subprogram_Declaration): Set new flag as needed.
1103 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1105 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
1106 when bounds of fixed type are static, to remove some spuerfluous
1107 implicit conversions and provide an accurate result when converting
1108 back and forth between the fixed point type and a floating point type.
1110 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1112 * exp_unst.adb (Unnest_Subprogram): Prevent creation of empty
1115 2018-05-28 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
1117 * exp_unst.adb (Check_Static_Type): Add argument to indicate node to be
1118 replaced, if any; all callers changed.
1119 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
1120 constant with private view so we take the address of that entity.
1121 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
1122 any; all callers changed. Handle N_Indexed_Component like
1123 N_Attribute_Reference. Add N_Type_Conversion case.
1124 (Visit_Node): Indexed references can be uplevel if the type isn't
1126 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
1127 been relocated, set first_named pointer in original node as well.
1129 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1131 * exp_aggr.adb (Flatten): Copy tree of expression in a component
1132 association with a range or a set of discrete choices, rather than
1133 relocating the node. This avoids inconsistencies in the tree when
1134 handling nested subprograms with uplevel references for LLVM.

1147 * libgnat/a-convec.adb (Query_Element): Minor cleanup: remove an
1148 unnecessary use of 'Unrestricted_Access.
1150 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
1152 * repinfo.adb (Expr_Value_S): New routine.
1153 (List_Linker_Section): Properly extract the value of the section
1156 2018-05-28 Patrick Bernardi <bernardi@adacore.com>
1158 * doc/gnat_ugn/building_executable_programs_with_gnat.rst: Update the
1159 description of the -D binder switch to reflect current usage.
1160 * gnat_ugn.texi: Regenerate.
1162 2018-05-28 Gary Dismukes <dismukes@adacore.com>

1187 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
1189 * sem_prag.adb (Process_Atomic_Independent_Shared_Volatile): Include
1190 the declarations of single concurrent types because they fall in the
1191 category of full type and object declarations.
1193 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
1195 * repinfo.adb (Compute_Max_Length): Skip _Parent component.

1198 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1200 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
1201 includes a call to function to which it applies. This may mean an
1202 omission of an attribute reference 'Result, in particular if the
1203 function is pqrameterless.
1205 2018-05-28 Justin Squirek <squirek@adacore.com>

1212 * sem_res.adb (Resolve_Range): Re-resolve the low bound of a range in
1213 GNATprove mode, as the order of resolution (low then high) means that

1219 * repinfo.adb (List_Array_Info): Start with an explicit blank line and
1220 end with the linker section, if any.
1221 (List_Entities): Do not output the linker section for record types,
1222 array types and variables.
1223 (Print_Expr): Factor out common processing for unary operators and
1224 special values. Adjust and reorder the various cases.
1225 (List_Object_Info): End with the linker section, if any.
1226 (List_Record_Info): Likewise.
1227 (List_Type_Info): Do not start with a blank line.
1229 2018-05-25 Nicolas Roche <roche@adacore.com>
1231 * libgnat/s-valrea.adb (Scan_Real): Abort computation once it is sure
1232 that the result will be either -infinite or +infinite.
1234 2018-05-25 Patrick Bernardi <bernardi@adacore.com>

1239 (Task_Storage_Size): Remove unused type.
1241 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1243 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
1244 of a fixed point type and the parent is a multiplying operation,
1245 resolve the operand with its own type because the context will impose a
1246 resulting type on the result of the multiplication by means of
1247 approriate conversion.
1249 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1251 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
1252 the in-place initialization aggregate created for pragmas
1253 Initialize_Scalars or Normalize_Scalars is performed with checks
1256 2018-05-25 Arnaud Charlet <charlet@adacore.com>
1258 * exp_aggr.adb (Convert_To_Positional): Bump default for
1259 Max_Others_Replicate to 32. Update comments.
1260 * osint.ads (Unknown_Attributes): No longer pretend this is a constant.
1261 (No_File_Info_Cache): Initialize separately.

1272 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1274 * exp_aggr.adb (Flatten): A quantified expression cannot be duplicated
1275 in an others clause to prevent visibility issues with the generated

1280 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1282 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
1283 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
1284 into three distring cases rather than in one loop which attempts to
1285 handle all three cases. This rewrite eliminates an issue where the last
1286 frame of the stack cannot be freed, thus causing the memory range of a
1287 new frame to approach the overflow point of the memory index type.
1288 Since the overflow is logically treated as a
1289 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
1290 (SS_Allocate_Static): New routine. The routine factorizes the static
1291 secondary stack-related code from the former SS_Allocate.
1293 2018-05-25 Sergey Rybin <rybin@adacore.com>
1295 * doc/gnat_ugn/gnat_and_program_execution.rst: Add description of '-U'
1296 option for gnatelim.
1298 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1300 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
1301 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
1302 is created when the proper body of the stub is analyzed.
1303 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
1304 is the proper body of a subunit, the cloned body must be inserted in
1305 the declarative list that contains the stub.
1307 2018-05-25 Justin Squirek <squirek@adacore.com>
1309 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
1310 generate code for 6.5(8-10) so that we don't get an assertion error
1311 when dealing with an incomplete return type.
1313 2018-05-25 Arnaud Charlet <charlet@adacore.com>
1315 * pprint.adb (Expression_Name): Strip too long expressions to avoid
1316 carrying very large strings.

1342 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1344 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
1345 Validate_Derived_Type_Instance, to verify that all interfaces
1346 implemented by the formal type are also implemented by the actual. The
1347 verification is complicated when an interface of the formal is declared
1348 in a generic unit and the actual is declared in an instance of it.
1349 There is currently no mechanism to relate an interface declared within
1350 a generic to the corresponding interface in an instance, so we must
1351 traverse the list of interfaces of the actual, looking for a name
1352 match, and verifying that that interface is declared in an instance.
1354 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
1356 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra
1357 assertions; replace function versions of Next_Formal/Next_Actual with
1358 their procedural versions (which are more concise).

1392 boolean type with convention C.
1393 * libgnat/i-cexten.ads (bool): Change to boolean with convention C.
1394 * gcc-interface/decl.c (gnat_to_gnu_entity): Add new local variable
1395 FOREIGN and use it throughout the function.
1396 <E_Enumeration_Type>: Set precision 1 on boolean types with foreign
1398 <E_Enumeration_Subtype>: Likewise for subtypes.
1399 <E_Record_Type>: Force the size of a storage unit on empty classes.
1400 * gcc-interface/utils.c (make_type_from_size) <BOOLEAN_TYPE>: Skip
1401 boolean types with precision 1 if the size is the expected one.

1419 prefixes of array attributes, to prefixes that are entity names whose
1420 type is constrained.
1421 (Note_Uplevel_Bound): Verify that the bound is declared in an enclosing
1422 subprogram, as itype created for loops in pre/postcondition may appear
1423 in loops at the library level.
1425 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1427 * sem_ch13.adb (Build_Predicate_Functions): The predicate function
1428 declaration is inserted into the tree and analyzed at that point, so
1429 should not be reinserted when the body is constructed. Inside a
1430 generic, ensure that the body is not inserted twice in the tree.
1432 2018-05-25 Yannick Moy <moy@adacore.com>

1465 2018-05-24 Javier Miranda <miranda@adacore.com>
1467 * exp_ch8.adb (Build_Body_For_Renaming): Adding support to build the

2525 Address, and type of Low, High to Storage_Offset.
2526 (Low): Rename as Low_Address and convey that the return value is a
2527 runtime reference accounting for a load address.

2588 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
2589 delegate the secondary stack management when there is no suitable
2590 transient context, and the transient scope was intended to manage the

2592 transient scope creation logic by special casing assignment statements
2593 of controlled components for type initialization procedures.

2595 the comment on usage.
2596 (Find_Transient_Context): Change the initinte loop into a while loop.

2598 contexts because they rely on special processing. Assignment statements
2599 are now treated as a normal transient context, special cases are
2600 handled by the caller. Add special processing for pragma Check.
2601 (Is_OK_Construct): Removed. Its functionality has been merged in
2602 routine Find_Transient_Context.
2603 * sem_ch5.adb (Check_Call): Reimplemented. Add code to properly
2604 retrieve the subprogram being invoked. Use a more accurate predicate

2808 suitable construct to wrap, and the transient scope was intended to
2809 manage the secondary stack.
2810 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
2811 is a valid boundary for a transient expression which comes from the
2812 statements of the alternative, otherwise alternatives cannot be
2813 wrapped. Assignments of controlled objects which have controlled
2814 actions suppressed now stop the traversal as there is no point in
2815 looking for an enclosing construct. Add several N_xxx_Body choices to
2816 the termination conditions for completeness.

2823 (Resolve_Actuals): Account for additional cases where finalization
2824 actions are required by utilizing predicate Needs_Finalization rather
2826 (Resolve_Call): Type initialization procedures can now utilize
2827 transient scopes to manage the secondary stack, thus preventing leaks
2828 during initialization. Remove the previous kludgy algorithm which
2829 attempts to manage the secondary stack at the object creation site.

2877 in the generic unless they reference a formal subprogram. Clarify

3015 relocated instead of evaluated. Discriminant of the corresponding
3016 record type is referenced rather than the type discriminant.
3017 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
3018 Secondary_Stack_Size rep item checks to only look for the pragma rep.
3019 * sem_ch13.adb (Analyze_One_Aspect): Transform
3020 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
3021 because the attribute does not have visibility on a task type's
3022 discriminants when the type's definition is expanded.
3023 (Analyze_Attribute_Definition_Clause): Remove handling of
3024 Attribute_Secondary_Stack_Size.
3025 * snames.adb-tmpl, snames.ads-tmpl: Remove
3026 Attribute_Secondary_Stack_Size, no longer used.

3030 * sem_ch8.adb: Minor comment fix.
3032 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3034 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
3035 individual action because the action may denote a complex expression,
3036 such as a case statement, which in turn may contain additional
3039 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3041 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
3042 analysis on a copy of the expression with a copy of the index variable,
3043 because full expansion will rewrite construct into a loop with the
3044 original loop variable.
3045 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
3046 expression is an iterated component association. Full analysis takes
3047 place when construct is rewritten as a loop.
3048 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
3049 is not safe for in-place assignment.
3050 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
3051 entity with no homonym and no other entity in the scope.
3053 2018-01-11 Justin Squirek <squirek@adacore.com>
3055 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
3056 message to be printed on the pragma argument identifier.
3058 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3060 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
3061 entity of the generated invariant procedure in order to construct a
3062 proper entity chain.

3066 * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
3069 2018-01-11 Arnaud Charlet <charlet@adacore.com>
3071 * einfo.ads, einfo.adb (Activation_Record_Component,
3072 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
3073 Allow E_Discriminant.
3075 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
3077 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
3078 for atomic access once the component size is taken into account and
3079 also do it if the component type is Atomic or Volatile_Full_Access.
3081 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
3083 * gnatvsn.ads: Bump copyright year.
