732 comment about the memset case.
734 2018-05-30 Bob Duff <duff@adacore.com>
736 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
737 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
738 We need to analyze it as part of analyzing the block, so that if the
739 call to Element that initializes Elmt_Decl returns on the secondary
740 stack, the block will ss_mark/ss_release. This block is inside the
741 loop; we don't want to leak memory until the loop exits. The purpose
742 of analyzing Elmt_Decl first was to catch the error of modifying it,
743 which is illegal because it's a loop parameter. The above causes us to
744 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
745 it on the Element entity, so we end up with an E_Variable node with the
747 * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.
748 * sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop
749 parameter not allowed" error if Is_Loop_Parameter.
750 * sem_util.adb (Is_Variable): Return False if Is_Loop_Parameter, to
751 trigger the call to Diagnose_Non_Variable_Lhs.

755 * checks.adb (Apply_Scalar_Range_Check):

762 * exp_unst.adb: Search specification of main unit as well, for
765 2018-05-30 Ed Schonberg <schonberg@adacore.com>
767 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
768 a package body that is a compilation unit may contain blocks that
769 declare local subprograms. In Subprogram_Unnesting Mode such
770 subprograms must be handled as nested inside the (implicit) elaboration
771 procedure that executes that statement part. To handle properly uplevel
772 references we construct that subprogram explicitly, to contain blocks
773 and inner subprograms, The statement part of the compilation unit
774 becomes a call to this subprogram. This is only done if blocks are
775 present in the statement list of the body.
777 2018-05-30 Bob Duff <duff@adacore.com>

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

1048 * lib-writ.adb (Write_ALI): Cleanup: avoid use of global var; call new
1050 * libgnat/s-casuti.ads, libgnat/s-casuti.adb (To_Upper, To_Lower,
1051 To_Mixed): New functions.
1052 * osint.adb: Cleanup: use Is_Directory_Separator, which correctly
1053 allows both '\' and '/' on Windows.
1055 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
1057 * repinfo.ads: Minor fixes and tweaks in comments.

1081 * exp_unst.adb (Visit_Node): For indexed components and attribute
1082 references, examine index expressions or associated expressions as well
1083 to record uplevel references.
1084 (Vist_Node): For function and procedure calls, if a formal is an
1085 unconstrained array and the actual is constrained, check whether bounds
1086 of actual have uplevel references.
1088 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1090 * einfo.ads, einfo.adb: Exceptions can be uplevel references, and thus
1091 they can appear as components of activation records.

1097 * exp_ch4.adb (Expand_Composite_Equality): Compute whether the size
1098 depends on a discriminant manually instead of using the predicate
1099 Size_Depends_On_Discriminant in the array type case.
1101 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1103 * exp_unst.adb (Check_Static_Type): For a record subtype, check
1104 discriminant constraints as well.
1105 (Visit_Node): For a selected component, check type of prefix, as is
1106 done for indexed components and slices.
1108 2018-05-28 Javier Miranda <miranda@adacore.com>
1110 * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
1111 value when converting a float value to a fixed-point value. This is
1112 required for CCG because it handles fixed-point types by means of
1113 unsigned integer type variables. The range check is now performed using
1114 the integer value stored in this temporary.
1116 2018-05-28 Yannick Moy <moy@adacore.com>
1118 * sem_util.adb (Is_OK_Volatile_Context): Add attributes First, Last and

1129 (Inherited_Subprograms): Instance of Generic_Inherited_Subprograms with
1130 Sem_Disp.Find_Dispatching_Type.
1131 (Is_Overriding_Subprogram): Instance of
1132 Generic_Is_Overriding_Subprogram with Sem_Disp.Find_Dispatching_Type.
1133 (Inheritance_Utilities_Inst): Instance of Inheritance_Utilities
1134 with Sem_Disp.Find_Dispatching_Type.
1136 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
1138 * exp_ch4.adb (Expand_Composite_Equality): For a composite (or FP)
1139 component type, do not expand array equality using the unconstrained
1140 base type, except for the case where the bounds of the type depend on a
1143 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1145 * einfo.ads, einfo.adb (Needs_Activation_Record): New flag on
1146 access-to-subprogram types, to indicate that an indirect call through
1147 such a type requires an activation record when compiling for LLVM.
1148 * sem_ch3.adb (Access_Subprogram_Declaration): Set new flag as needed.
1150 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1152 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
1153 when bounds of fixed type are static, to remove some spuerfluous
1154 implicit conversions and provide an accurate result when converting
1155 back and forth between the fixed point type and a floating point type.
1157 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1159 * exp_unst.adb (Unnest_Subprogram): Prevent creation of empty
1162 2018-05-28 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
1164 * exp_unst.adb (Check_Static_Type): Add argument to indicate node to be
1165 replaced, if any; all callers changed.
1166 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
1167 constant with private view so we take the address of that entity.
1168 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
1169 any; all callers changed. Handle N_Indexed_Component like
1170 N_Attribute_Reference. Add N_Type_Conversion case.
1171 (Visit_Node): Indexed references can be uplevel if the type isn't
1173 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
1174 been relocated, set first_named pointer in original node as well.
1176 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1178 * exp_aggr.adb (Flatten): Copy tree of expression in a component
1179 association with a range or a set of discrete choices, rather than
1180 relocating the node. This avoids inconsistencies in the tree when
1181 handling nested subprograms with uplevel references for LLVM.

1195 unnecessary use of 'Unrestricted_Access.
1197 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
1199 * repinfo.adb (Expr_Value_S): New routine.
1200 (List_Linker_Section): Properly extract the value of the section
1203 2018-05-28 Patrick Bernardi <bernardi@adacore.com>
1205 * doc/gnat_ugn/building_executable_programs_with_gnat.rst: Update the
1206 description of the -D binder switch to reflect current usage.
1207 * gnat_ugn.texi: Regenerate.
1209 2018-05-28 Gary Dismukes <dismukes@adacore.com>

1234 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
1236 * sem_prag.adb (Process_Atomic_Independent_Shared_Volatile): Include
1237 the declarations of single concurrent types because they fall in the
1238 category of full type and object declarations.
1240 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
1242 * repinfo.adb (Compute_Max_Length): Skip _Parent component.

1245 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1247 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
1248 includes a call to function to which it applies. This may mean an
1249 omission of an attribute reference 'Result, in particular if the
1250 function is pqrameterless.
1252 2018-05-28 Justin Squirek <squirek@adacore.com>
1254 * sem_ch8.adb (Find_Expanded_Name): Add extra guard to make sure the

1259 * sem_res.adb (Resolve_Range): Re-resolve the low bound of a range in
1260 GNATprove mode, as the order of resolution (low then high) means that

1264 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
1266 * repinfo.adb (List_Array_Info): Start with an explicit blank line and
1267 end with the linker section, if any.
1268 (List_Entities): Do not output the linker section for record types,
1269 array types and variables.
1270 (Print_Expr): Factor out common processing for unary operators and
1271 special values. Adjust and reorder the various cases.
1272 (List_Object_Info): End with the linker section, if any.
1273 (List_Record_Info): Likewise.
1274 (List_Type_Info): Do not start with a blank line.
1276 2018-05-25 Nicolas Roche <roche@adacore.com>
1278 * libgnat/s-valrea.adb (Scan_Real): Abort computation once it is sure
1279 that the result will be either -infinite or +infinite.
1281 2018-05-25 Patrick Bernardi <bernardi@adacore.com>

1286 (Task_Storage_Size): Remove unused type.
1288 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1290 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
1291 of a fixed point type and the parent is a multiplying operation,
1292 resolve the operand with its own type because the context will impose a
1293 resulting type on the result of the multiplication by means of
1294 approriate conversion.
1296 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1298 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
1299 the in-place initialization aggregate created for pragmas
1300 Initialize_Scalars or Normalize_Scalars is performed with checks
1303 2018-05-25 Arnaud Charlet <charlet@adacore.com>
1305 * exp_aggr.adb (Convert_To_Positional): Bump default for
1306 Max_Others_Replicate to 32. Update comments.
1307 * osint.ads (Unknown_Attributes): No longer pretend this is a constant.
1308 (No_File_Info_Cache): Initialize separately.

1313 * sem_res.adb (Resolve_Membership_Op): Allow the use of the membership
1314 test when the left operand is a class-wide interface and the right
1315 operand is not a class-wide type.
1316 * exp_ch4.adb (Tagged_Membership): Adding support for interface as the
1319 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1321 * exp_aggr.adb (Flatten): A quantified expression cannot be duplicated
1322 in an others clause to prevent visibility issues with the generated
1324 (Component_OK_For_Backend): Return false for a quantified expression.
1325 (Check_Static_Component): Ditto.
1327 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1329 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
1330 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
1331 into three distring cases rather than in one loop which attempts to
1332 handle all three cases. This rewrite eliminates an issue where the last
1333 frame of the stack cannot be freed, thus causing the memory range of a
1334 new frame to approach the overflow point of the memory index type.
1335 Since the overflow is logically treated as a
1336 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
1337 (SS_Allocate_Static): New routine. The routine factorizes the static
1338 secondary stack-related code from the former SS_Allocate.
1340 2018-05-25 Sergey Rybin <rybin@adacore.com>
1342 * doc/gnat_ugn/gnat_and_program_execution.rst: Add description of '-U'
1343 option for gnatelim.
1345 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1347 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
1348 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
1349 is created when the proper body of the stub is analyzed.
1350 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
1351 is the proper body of a subunit, the cloned body must be inserted in
1352 the declarative list that contains the stub.
1354 2018-05-25 Justin Squirek <squirek@adacore.com>
1356 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
1357 generate code for 6.5(8-10) so that we don't get an assertion error
1358 when dealing with an incomplete return type.
1360 2018-05-25 Arnaud Charlet <charlet@adacore.com>
1362 * pprint.adb (Expression_Name): Strip too long expressions to avoid
1363 carrying very large strings.

1389 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1391 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
1392 Validate_Derived_Type_Instance, to verify that all interfaces
1393 implemented by the formal type are also implemented by the actual. The
1394 verification is complicated when an interface of the formal is declared
1395 in a generic unit and the actual is declared in an instance of it.
1396 There is currently no mechanism to relate an interface declared within
1397 a generic to the corresponding interface in an instance, so we must
1398 traverse the list of interfaces of the actual, looking for a name
1399 match, and verifying that that interface is declared in an instance.
1401 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
1403 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra
1404 assertions; replace function versions of Next_Formal/Next_Actual with
1405 their procedural versions (which are more concise).

1440 * libgnat/i-cexten.ads (bool): Change to boolean with convention C.
1441 * gcc-interface/decl.c (gnat_to_gnu_entity): Add new local variable

1443 <E_Enumeration_Type>: Set precision 1 on boolean types with foreign
1445 <E_Enumeration_Subtype>: Likewise for subtypes.
1446 <E_Record_Type>: Force the size of a storage unit on empty classes.
1447 * gcc-interface/utils.c (make_type_from_size) <BOOLEAN_TYPE>: Skip
1448 boolean types with precision 1 if the size is the expected one.

1466 prefixes of array attributes, to prefixes that are entity names whose
1467 type is constrained.
1468 (Note_Uplevel_Bound): Verify that the bound is declared in an enclosing
1469 subprogram, as itype created for loops in pre/postcondition may appear
1470 in loops at the library level.
1472 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1474 * sem_ch13.adb (Build_Predicate_Functions): The predicate function
1475 declaration is inserted into the tree and analyzed at that point, so
1476 should not be reinserted when the body is constructed. Inside a
1477 generic, ensure that the body is not inserted twice in the tree.

2527 of empty string when argv[0] couldn't be found on PATH.
2528 (Enable_Cache): Raise Program_Error instead of attempting a null
2529 pointer dereference when the Exec_Module initialization failed.

2633 2018-05-21 Hristian Kirtchev <kirtchev@adacore.com>
2635 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
2636 delegate the secondary stack management when there is no suitable
2637 transient context, and the transient scope was intended to manage the

2639 transient scope creation logic by special casing assignment statements
2640 of controlled components for type initialization procedures.
2641 (Find_Node_To_Be_Wrapped): Renamed to Find_Transient_Context. Update
2642 the comment on usage.
2643 (Find_Transient_Context): Change the initinte loop into a while loop.

2645 contexts because they rely on special processing. Assignment statements
2646 are now treated as a normal transient context, special cases are
2647 handled by the caller. Add special processing for pragma Check.
2648 (Is_OK_Construct): Removed. Its functionality has been merged in
2649 routine Find_Transient_Context.
2650 * sem_ch5.adb (Check_Call): Reimplemented. Add code to properly
2651 retrieve the subprogram being invoked. Use a more accurate predicate

2858 is a valid boundary for a transient expression which comes from the

2871 actions are required by utilizing predicate Needs_Finalization rather
2873 (Resolve_Call): Type initialization procedures can now utilize
2874 transient scopes to manage the secondary stack, thus preventing leaks
2875 during initialization. Remove the previous kludgy algorithm which
2876 attempts to manage the secondary stack at the object creation site.

3023 either implicitly or explicitly withed.
3024 (Is_Implicit_With_Clause): New routine.
3025 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
3026 confusion with the with clause attribute by the same name.
3027 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
3028 * rtsfind.adb (Maybe_Add_With): Code cleanup.
3029 * sem_ch8.adb (Present_System_Aux): Code cleanup.
3030 * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
3032 (Implicit_With_On_Parent): Mark the with clause as generated for a
3034 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
3035 instantiation are no longer marked as Implicit_With_From_Instantiation
3036 because they are already marked as implicit.
3037 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
3038 which marks implicit with clauses as related to an instantiation.
3039 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
3040 (Parent_With): New routine.
3041 (Set_Implicit_With_From_Instantiation): Removed.
3042 (Set_Parent_With): New routine.
3043 * sinfo.ads: Update the documentation of attribute Implicit_With.
3044 Remove attribute Implicit_With_From_Instantiation along with
3045 occurrences in nodes. Add attribute Parent_With along with occurrences
3047 (Implicit_With_From_Instantiation): Removed along with pragma Inline.
3048 (Parent_With): New routine along with pragma Inline.
3049 (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.
3050 (Set_Parent_With): New routine along with pragma Inline.

3054 * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
3055 entity when the enclosing construct is a body.
3057 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
3059 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
3060 Secondary_Stack_Size handling as a pragma is now generated for the
3061 corresponding aspect instead of an attribute. Pragma expression is
3062 relocated instead of evaluated. Discriminant of the corresponding
3063 record type is referenced rather than the type discriminant.
3064 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
3065 Secondary_Stack_Size rep item checks to only look for the pragma rep.
3066 * sem_ch13.adb (Analyze_One_Aspect): Transform
3067 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
3068 because the attribute does not have visibility on a task type's
3069 discriminants when the type's definition is expanded.
3070 (Analyze_Attribute_Definition_Clause): Remove handling of
3071 Attribute_Secondary_Stack_Size.
3072 * snames.adb-tmpl, snames.ads-tmpl: Remove
3073 Attribute_Secondary_Stack_Size, no longer used.
3075 2018-01-11 Justin Squirek <squirek@adacore.com>
3077 * sem_ch8.adb: Minor comment fix.
3079 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3081 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
3082 individual action because the action may denote a complex expression,
3083 such as a case statement, which in turn may contain additional
3086 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3088 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
3089 analysis on a copy of the expression with a copy of the index variable,
3090 because full expansion will rewrite construct into a loop with the
3091 original loop variable.
3092 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
3093 expression is an iterated component association. Full analysis takes
3094 place when construct is rewritten as a loop.
3095 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
3096 is not safe for in-place assignment.
3097 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
3098 entity with no homonym and no other entity in the scope.
3100 2018-01-11 Justin Squirek <squirek@adacore.com>
3102 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
3103 message to be printed on the pragma argument identifier.
3105 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3107 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
3108 entity of the generated invariant procedure in order to construct a
3109 proper entity chain.
3111 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
3113 * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
3116 2018-01-11 Arnaud Charlet <charlet@adacore.com>
3118 * einfo.ads, einfo.adb (Activation_Record_Component,
3119 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
3120 Allow E_Discriminant.
3122 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
3124 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
3125 for atomic access once the component size is taken into account and
3126 also do it if the component type is Atomic or Volatile_Full_Access.
3128 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
3130 * gnatvsn.ads: Bump copyright year.

3133 Alan Hayward <alan.hayward@arm.com>
3134 David Sherwood <david.sherwood@arm.com>
3136 * gcc-interface/misc.c (enumerate_modes): Treat GET_MODE_BITSIZE

3147 Alan Hayward <alan.hayward@arm.com>
3148 David Sherwood <david.sherwood@arm.com>
3150 * gcc-interface/utils.c (gnat_types_compatible_p): Handle
3151 polynomial TYPE_VECTOR_SUBPARTS.
