763 comment about the memset case.
765 2018-05-30 Bob Duff <duff@adacore.com>
767 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
768 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
769 We need to analyze it as part of analyzing the block, so that if the
770 call to Element that initializes Elmt_Decl returns on the secondary
771 stack, the block will ss_mark/ss_release. This block is inside the
772 loop; we don't want to leak memory until the loop exits. The purpose
773 of analyzing Elmt_Decl first was to catch the error of modifying it,
774 which is illegal because it's a loop parameter. The above causes us to
775 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
776 it on the Element entity, so we end up with an E_Variable node with the
778 * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.
779 * sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop
780 parameter not allowed" error if Is_Loop_Parameter.
781 * sem_util.adb (Is_Variable): Return False if Is_Loop_Parameter, to
782 trigger the call to Diagnose_Non_Variable_Lhs.

786 * checks.adb (Apply_Scalar_Range_Check):

796 2018-05-30 Ed Schonberg <schonberg@adacore.com>
798 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
799 a package body that is a compilation unit may contain blocks that
800 declare local subprograms. In Subprogram_Unnesting Mode such
801 subprograms must be handled as nested inside the (implicit) elaboration
802 procedure that executes that statement part. To handle properly uplevel
803 references we construct that subprogram explicitly, to contain blocks
804 and inner subprograms, The statement part of the compilation unit
805 becomes a call to this subprogram. This is only done if blocks are
806 present in the statement list of the body.
808 2018-05-30 Bob Duff <duff@adacore.com>

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

1081 * libgnat/s-casuti.ads, libgnat/s-casuti.adb (To_Upper, To_Lower,
1082 To_Mixed): New functions.
1083 * osint.adb: Cleanup: use Is_Directory_Separator, which correctly
1084 allows both '\' and '/' on Windows.

1112 * exp_unst.adb (Visit_Node): For indexed components and attribute
1113 references, examine index expressions or associated expressions as well
1114 to record uplevel references.
1115 (Vist_Node): For function and procedure calls, if a formal is an
1116 unconstrained array and the actual is constrained, check whether bounds
1117 of actual have uplevel references.
1119 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1121 * einfo.ads, einfo.adb: Exceptions can be uplevel references, and thus
1122 they can appear as components of activation records.

1129 depends on a discriminant manually instead of using the predicate
1130 Size_Depends_On_Discriminant in the array type case.
1132 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1134 * exp_unst.adb (Check_Static_Type): For a record subtype, check
1135 discriminant constraints as well.
1136 (Visit_Node): For a selected component, check type of prefix, as is
1137 done for indexed components and slices.
1139 2018-05-28 Javier Miranda <miranda@adacore.com>
1141 * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
1142 value when converting a float value to a fixed-point value. This is
1143 required for CCG because it handles fixed-point types by means of
1144 unsigned integer type variables. The range check is now performed using
1145 the integer value stored in this temporary.
1147 2018-05-28 Yannick Moy <moy@adacore.com>
1149 * sem_util.adb (Is_OK_Volatile_Context): Add attributes First, Last and

1160 (Inherited_Subprograms): Instance of Generic_Inherited_Subprograms with
1161 Sem_Disp.Find_Dispatching_Type.
1162 (Is_Overriding_Subprogram): Instance of
1163 Generic_Is_Overriding_Subprogram with Sem_Disp.Find_Dispatching_Type.

1165 with Sem_Disp.Find_Dispatching_Type.
1167 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
1169 * exp_ch4.adb (Expand_Composite_Equality): For a composite (or FP)
1170 component type, do not expand array equality using the unconstrained
1171 base type, except for the case where the bounds of the type depend on a
1174 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1176 * einfo.ads, einfo.adb (Needs_Activation_Record): New flag on
1177 access-to-subprogram types, to indicate that an indirect call through
1178 such a type requires an activation record when compiling for LLVM.
1179 * sem_ch3.adb (Access_Subprogram_Declaration): Set new flag as needed.
1181 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1183 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
1184 when bounds of fixed type are static, to remove some spuerfluous
1185 implicit conversions and provide an accurate result when converting
1186 back and forth between the fixed point type and a floating point type.
1188 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1190 * exp_unst.adb (Unnest_Subprogram): Prevent creation of empty
1193 2018-05-28 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
1195 * exp_unst.adb (Check_Static_Type): Add argument to indicate node to be
1196 replaced, if any; all callers changed.
1197 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
1198 constant with private view so we take the address of that entity.
1199 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
1200 any; all callers changed. Handle N_Indexed_Component like
1201 N_Attribute_Reference. Add N_Type_Conversion case.
1202 (Visit_Node): Indexed references can be uplevel if the type isn't
1204 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
1205 been relocated, set first_named pointer in original node as well.
1207 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1209 * exp_aggr.adb (Flatten): Copy tree of expression in a component
1210 association with a range or a set of discrete choices, rather than
1211 relocating the node. This avoids inconsistencies in the tree when
1212 handling nested subprograms with uplevel references for LLVM.

1226 unnecessary use of 'Unrestricted_Access.
1228 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
1230 * repinfo.adb (Expr_Value_S): New routine.
1231 (List_Linker_Section): Properly extract the value of the section
1234 2018-05-28 Patrick Bernardi <bernardi@adacore.com>
1236 * doc/gnat_ugn/building_executable_programs_with_gnat.rst: Update the
1237 description of the -D binder switch to reflect current usage.
1238 * gnat_ugn.texi: Regenerate.
1240 2018-05-28 Gary Dismukes <dismukes@adacore.com>

1265 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
1267 * sem_prag.adb (Process_Atomic_Independent_Shared_Volatile): Include
1268 the declarations of single concurrent types because they fall in the
1269 category of full type and object declarations.
1271 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
1273 * repinfo.adb (Compute_Max_Length): Skip _Parent component.

1278 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
1279 includes a call to function to which it applies. This may mean an
1280 omission of an attribute reference 'Result, in particular if the
1281 function is pqrameterless.
1283 2018-05-28 Justin Squirek <squirek@adacore.com>

1290 * sem_res.adb (Resolve_Range): Re-resolve the low bound of a range in
1291 GNATprove mode, as the order of resolution (low then high) means that

1297 * repinfo.adb (List_Array_Info): Start with an explicit blank line and
1298 end with the linker section, if any.
1299 (List_Entities): Do not output the linker section for record types,
1300 array types and variables.
1301 (Print_Expr): Factor out common processing for unary operators and
1302 special values. Adjust and reorder the various cases.
1303 (List_Object_Info): End with the linker section, if any.
1304 (List_Record_Info): Likewise.
1305 (List_Type_Info): Do not start with a blank line.
1307 2018-05-25 Nicolas Roche <roche@adacore.com>
1309 * libgnat/s-valrea.adb (Scan_Real): Abort computation once it is sure
1310 that the result will be either -infinite or +infinite.
1312 2018-05-25 Patrick Bernardi <bernardi@adacore.com>

1317 (Task_Storage_Size): Remove unused type.
1319 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1321 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
1322 of a fixed point type and the parent is a multiplying operation,
1323 resolve the operand with its own type because the context will impose a
1324 resulting type on the result of the multiplication by means of
1325 approriate conversion.
1327 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1329 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
1330 the in-place initialization aggregate created for pragmas
1331 Initialize_Scalars or Normalize_Scalars is performed with checks
1334 2018-05-25 Arnaud Charlet <charlet@adacore.com>
1336 * exp_aggr.adb (Convert_To_Positional): Bump default for
1337 Max_Others_Replicate to 32. Update comments.
1338 * osint.ads (Unknown_Attributes): No longer pretend this is a constant.
1339 (No_File_Info_Cache): Initialize separately.

1344 * sem_res.adb (Resolve_Membership_Op): Allow the use of the membership
1345 test when the left operand is a class-wide interface and the right
1346 operand is not a class-wide type.
1347 * exp_ch4.adb (Tagged_Membership): Adding support for interface as the
1350 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1352 * exp_aggr.adb (Flatten): A quantified expression cannot be duplicated
1353 in an others clause to prevent visibility issues with the generated
1355 (Component_OK_For_Backend): Return false for a quantified expression.
1356 (Check_Static_Component): Ditto.
1358 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1360 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
1361 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
1362 into three distring cases rather than in one loop which attempts to
1363 handle all three cases. This rewrite eliminates an issue where the last
1364 frame of the stack cannot be freed, thus causing the memory range of a
1365 new frame to approach the overflow point of the memory index type.
1366 Since the overflow is logically treated as a
1367 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
1368 (SS_Allocate_Static): New routine. The routine factorizes the static
1369 secondary stack-related code from the former SS_Allocate.
1371 2018-05-25 Sergey Rybin <rybin@adacore.com>
1373 * doc/gnat_ugn/gnat_and_program_execution.rst: Add description of '-U'
1374 option for gnatelim.
1376 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1378 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
1379 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
1380 is created when the proper body of the stub is analyzed.
1381 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
1382 is the proper body of a subunit, the cloned body must be inserted in
1383 the declarative list that contains the stub.
1385 2018-05-25 Justin Squirek <squirek@adacore.com>
1387 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
1388 generate code for 6.5(8-10) so that we don't get an assertion error
1389 when dealing with an incomplete return type.
1391 2018-05-25 Arnaud Charlet <charlet@adacore.com>
1393 * pprint.adb (Expression_Name): Strip too long expressions to avoid
1394 carrying very large strings.

1420 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1422 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
1423 Validate_Derived_Type_Instance, to verify that all interfaces
1424 implemented by the formal type are also implemented by the actual. The
1425 verification is complicated when an interface of the formal is declared
1426 in a generic unit and the actual is declared in an instance of it.
1427 There is currently no mechanism to relate an interface declared within
1428 a generic to the corresponding interface in an instance, so we must
1429 traverse the list of interfaces of the actual, looking for a name
1430 match, and verifying that that interface is declared in an instance.
1432 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
1434 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra
1435 assertions; replace function versions of Next_Formal/Next_Actual with
1436 their procedural versions (which are more concise).

1470 boolean type with convention C.
1471 * libgnat/i-cexten.ads (bool): Change to boolean with convention C.
1472 * gcc-interface/decl.c (gnat_to_gnu_entity): Add new local variable

1474 <E_Enumeration_Type>: Set precision 1 on boolean types with foreign
1476 <E_Enumeration_Subtype>: Likewise for subtypes.
1477 <E_Record_Type>: Force the size of a storage unit on empty classes.
1478 * gcc-interface/utils.c (make_type_from_size) <BOOLEAN_TYPE>: Skip
1479 boolean types with precision 1 if the size is the expected one.

1496 * exp_unst.adb (Visit_Node): Restrict check for uplevel references in
1497 prefixes of array attributes, to prefixes that are entity names whose
1498 type is constrained.
1499 (Note_Uplevel_Bound): Verify that the bound is declared in an enclosing
1500 subprogram, as itype created for loops in pre/postcondition may appear
1501 in loops at the library level.
1503 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1505 * sem_ch13.adb (Build_Predicate_Functions): The predicate function
1506 declaration is inserted into the tree and analyzed at that point, so
1507 should not be reinserted when the body is constructed. Inside a
1508 generic, ensure that the body is not inserted twice in the tree.

2542 (Unit_Entity): New routine.
2543 * sem_prag.adb (Analyze_Pragma): Reimplement the handling of pragma
2544 Elaboration_Checks. The analysis now ensures that the pragma appears at
2545 the configuration level, and on the initial declaration of a unit.
2546 Other placements are either flagged as illegal, or ignored.

2664 2018-05-21 Hristian Kirtchev <kirtchev@adacore.com>
2666 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
2667 delegate the secondary stack management when there is no suitable
2668 transient context, and the transient scope was intended to manage the

2670 transient scope creation logic by special casing assignment statements
2671 of controlled components for type initialization procedures.
2672 (Find_Node_To_Be_Wrapped): Renamed to Find_Transient_Context. Update
2673 the comment on usage.
2674 (Find_Transient_Context): Change the initinte loop into a while loop.

2676 contexts because they rely on special processing. Assignment statements
2677 are now treated as a normal transient context, special cases are
2678 handled by the caller. Add special processing for pragma Check.

2680 routine Find_Transient_Context.
2681 * sem_ch5.adb (Check_Call): Reimplemented. Add code to properly

2906 during initialization. Remove the previous kludgy algorithm which
2907 attempts to manage the secondary stack at the object creation site.

3029 (SS_Init): Cover the case when bootstraping with an old compiler that
3030 does not set Default_SS_Size.
3032 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3034 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
3035 legality of an inherited operation that may require overriding, ignore
3036 primitive_wrappers that correspond to explicit operations that override
3037 an interface primitive.
3038 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
3039 operation to which the class-wide expression applies is a protected op.
3040 with a primitive_wrapper, verify that the updated inherited expression
3041 does not contain an internal call to a protected function. This
3042 completes the implementation of AI12-0166.
3044 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3046 * ali.adb: Document the remaining letters available for ALI lines.
3047 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
3048 * ali.ads: Update type With_Record. Field
3049 Implicit_With_From_Instantiation is no longer in use. Add field
3051 * csinfo.adb (CSinfo): Remove the setup for attribute
3052 Implicit_With_From_Instantiation.
3053 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
3054 either implicitly or explicitly withed.
3055 (Is_Implicit_With_Clause): New routine.
3056 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
3057 confusion with the with clause attribute by the same name.
3058 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
3059 * rtsfind.adb (Maybe_Add_With): Code cleanup.
3060 * sem_ch8.adb (Present_System_Aux): Code cleanup.
3061 * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
3063 (Implicit_With_On_Parent): Mark the with clause as generated for a
3065 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
3066 instantiation are no longer marked as Implicit_With_From_Instantiation
3067 because they are already marked as implicit.
3068 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
3069 which marks implicit with clauses as related to an instantiation.
3070 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
3071 (Parent_With): New routine.
3072 (Set_Implicit_With_From_Instantiation): Removed.
3073 (Set_Parent_With): New routine.
3074 * sinfo.ads: Update the documentation of attribute Implicit_With.
3075 Remove attribute Implicit_With_From_Instantiation along with
3076 occurrences in nodes. Add attribute Parent_With along with occurrences
3078 (Implicit_With_From_Instantiation): Removed along with pragma Inline.
3079 (Parent_With): New routine along with pragma Inline.
3080 (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.
3081 (Set_Parent_With): New routine along with pragma Inline.
3083 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3085 * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
3086 entity when the enclosing construct is a body.
3088 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
3090 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
3091 Secondary_Stack_Size handling as a pragma is now generated for the
3092 corresponding aspect instead of an attribute. Pragma expression is
3093 relocated instead of evaluated. Discriminant of the corresponding
3094 record type is referenced rather than the type discriminant.
3095 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
3096 Secondary_Stack_Size rep item checks to only look for the pragma rep.
3097 * sem_ch13.adb (Analyze_One_Aspect): Transform
3098 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
3099 because the attribute does not have visibility on a task type's
3100 discriminants when the type's definition is expanded.
3101 (Analyze_Attribute_Definition_Clause): Remove handling of
3102 Attribute_Secondary_Stack_Size.
3103 * snames.adb-tmpl, snames.ads-tmpl: Remove
3104 Attribute_Secondary_Stack_Size, no longer used.
3106 2018-01-11 Justin Squirek <squirek@adacore.com>
3108 * sem_ch8.adb: Minor comment fix.
3110 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3112 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
3113 individual action because the action may denote a complex expression,
3114 such as a case statement, which in turn may contain additional
3117 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3119 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
3120 analysis on a copy of the expression with a copy of the index variable,
3121 because full expansion will rewrite construct into a loop with the
3122 original loop variable.
3123 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
3124 expression is an iterated component association. Full analysis takes
3125 place when construct is rewritten as a loop.
3126 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
3127 is not safe for in-place assignment.
3128 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
3129 entity with no homonym and no other entity in the scope.
3131 2018-01-11 Justin Squirek <squirek@adacore.com>
3133 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
3134 message to be printed on the pragma argument identifier.
3136 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3138 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
3139 entity of the generated invariant procedure in order to construct a
3140 proper entity chain.
3142 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
3144 * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
3147 2018-01-11 Arnaud Charlet <charlet@adacore.com>
3149 * einfo.ads, einfo.adb (Activation_Record_Component,
3150 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
3151 Allow E_Discriminant.
3153 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
3155 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
3156 for atomic access once the component size is taken into account and
3157 also do it if the component type is Atomic or Volatile_Full_Access.
3159 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
3161 * gnatvsn.ads: Bump copyright year.

3164 Alan Hayward <alan.hayward@arm.com>
3165 David Sherwood <david.sherwood@arm.com>
3167 * gcc-interface/misc.c (enumerate_modes): Treat GET_MODE_BITSIZE

3171 Alan Hayward <alan.hayward@arm.com>
3172 David Sherwood <david.sherwood@arm.com>

3178 Alan Hayward <alan.hayward@arm.com>
3179 David Sherwood <david.sherwood@arm.com>
3181 * gcc-interface/utils.c (gnat_types_compatible_p): Handle
3182 polynomial TYPE_VECTOR_SUBPARTS.
3184 2018-01-03 Richard Sandiford <richard.sandiford@linaro.org>
3185 Alan Hayward <alan.hayward@arm.com>
3186 David Sherwood <david.sherwood@arm.com>

3191 2018-01-03 Jakub Jelinek <jakub@redhat.com>
3193 Update copyright years.
3195 * gnat_ugn.texi: Bump @copying's copyright year.
