809 2018-05-30 Bob Duff <duff@adacore.com>
811 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
812 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
813 We need to analyze it as part of analyzing the block, so that if the
814 call to Element that initializes Elmt_Decl returns on the secondary
815 stack, the block will ss_mark/ss_release. This block is inside the
816 loop; we don't want to leak memory until the loop exits. The purpose
817 of analyzing Elmt_Decl first was to catch the error of modifying it,
818 which is illegal because it's a loop parameter. The above causes us to
819 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
820 it on the Element entity, so we end up with an E_Variable node with the
822 * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.
823 * sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop
824 parameter not allowed" error if Is_Loop_Parameter.

842 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
843 a package body that is a compilation unit may contain blocks that
844 declare local subprograms. In Subprogram_Unnesting Mode such
845 subprograms must be handled as nested inside the (implicit) elaboration
846 procedure that executes that statement part. To handle properly uplevel
847 references we construct that subprogram explicitly, to contain blocks
848 and inner subprograms, The statement part of the compilation unit
849 becomes a call to this subprogram. This is only done if blocks are
850 present in the statement list of the body.

1126 To_Mixed): New functions.
1127 * osint.adb: Cleanup: use Is_Directory_Separator, which correctly
1128 allows both '\' and '/' on Windows.

1157 references, examine index expressions or associated expressions as well
1158 to record uplevel references.
1159 (Vist_Node): For function and procedure calls, if a formal is an
1160 unconstrained array and the actual is constrained, check whether bounds
1161 of actual have uplevel references.
1163 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1165 * einfo.ads, einfo.adb: Exceptions can be uplevel references, and thus
1166 they can appear as components of activation records.

1173 depends on a discriminant manually instead of using the predicate
1174 Size_Depends_On_Discriminant in the array type case.
1176 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1178 * exp_unst.adb (Check_Static_Type): For a record subtype, check
1179 discriminant constraints as well.
1180 (Visit_Node): For a selected component, check type of prefix, as is
1181 done for indexed components and slices.
1183 2018-05-28 Javier Miranda <miranda@adacore.com>
1185 * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
1186 value when converting a float value to a fixed-point value. This is
1187 required for CCG because it handles fixed-point types by means of
1188 unsigned integer type variables. The range check is now performed using
1189 the integer value stored in this temporary.
1191 2018-05-28 Yannick Moy <moy@adacore.com>
1193 * sem_util.adb (Is_OK_Volatile_Context): Add attributes First, Last and

1209 with Sem_Disp.Find_Dispatching_Type.
1211 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
1213 * exp_ch4.adb (Expand_Composite_Equality): For a composite (or FP)
1214 component type, do not expand array equality using the unconstrained
1215 base type, except for the case where the bounds of the type depend on a
1218 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1220 * einfo.ads, einfo.adb (Needs_Activation_Record): New flag on
1221 access-to-subprogram types, to indicate that an indirect call through
1222 such a type requires an activation record when compiling for LLVM.
1223 * sem_ch3.adb (Access_Subprogram_Declaration): Set new flag as needed.
1225 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1227 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
1228 when bounds of fixed type are static, to remove some spuerfluous
1229 implicit conversions and provide an accurate result when converting
1230 back and forth between the fixed point type and a floating point type.
1232 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1234 * exp_unst.adb (Unnest_Subprogram): Prevent creation of empty
1237 2018-05-28 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
1239 * exp_unst.adb (Check_Static_Type): Add argument to indicate node to be
1240 replaced, if any; all callers changed.
1241 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
1242 constant with private view so we take the address of that entity.
1243 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
1244 any; all callers changed. Handle N_Indexed_Component like
1245 N_Attribute_Reference. Add N_Type_Conversion case.
1246 (Visit_Node): Indexed references can be uplevel if the type isn't
1248 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
1249 been relocated, set first_named pointer in original node as well.
1251 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1253 * exp_aggr.adb (Flatten): Copy tree of expression in a component
1254 association with a range or a set of discrete choices, rather than
1255 relocating the node. This avoids inconsistencies in the tree when
1256 handling nested subprograms with uplevel references for LLVM.

1269 * libgnat/a-convec.adb (Query_Element): Minor cleanup: remove an
1270 unnecessary use of 'Unrestricted_Access.
1272 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
1274 * repinfo.adb (Expr_Value_S): New routine.

1278 2018-05-28 Patrick Bernardi <bernardi@adacore.com>
1280 * doc/gnat_ugn/building_executable_programs_with_gnat.rst: Update the
1281 description of the -D binder switch to reflect current usage.
1282 * gnat_ugn.texi: Regenerate.
1284 2018-05-28 Gary Dismukes <dismukes@adacore.com>

1309 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
1311 * sem_prag.adb (Process_Atomic_Independent_Shared_Volatile): Include
1312 the declarations of single concurrent types because they fall in the
1313 category of full type and object declarations.
1315 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
1317 * repinfo.adb (Compute_Max_Length): Skip _Parent component.

1320 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1322 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
1323 includes a call to function to which it applies. This may mean an
1324 omission of an attribute reference 'Result, in particular if the
1325 function is pqrameterless.
1327 2018-05-28 Justin Squirek <squirek@adacore.com>

1334 * sem_res.adb (Resolve_Range): Re-resolve the low bound of a range in
1335 GNATprove mode, as the order of resolution (low then high) means that

1339 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
1341 * repinfo.adb (List_Array_Info): Start with an explicit blank line and
1342 end with the linker section, if any.
1343 (List_Entities): Do not output the linker section for record types,
1344 array types and variables.
1345 (Print_Expr): Factor out common processing for unary operators and
1346 special values. Adjust and reorder the various cases.
1347 (List_Object_Info): End with the linker section, if any.
1348 (List_Record_Info): Likewise.
1349 (List_Type_Info): Do not start with a blank line.
1351 2018-05-25 Nicolas Roche <roche@adacore.com>
1353 * libgnat/s-valrea.adb (Scan_Real): Abort computation once it is sure
1354 that the result will be either -infinite or +infinite.
1356 2018-05-25 Patrick Bernardi <bernardi@adacore.com>
1358 * libgnat/s-parame.ads, libgnat/s-parame__vxworks.ads,

1360 Expand range of type to match the address space of the target.
1361 (Task_Storage_Size): Remove unused type.
1363 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1365 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
1366 of a fixed point type and the parent is a multiplying operation,
1367 resolve the operand with its own type because the context will impose a
1368 resulting type on the result of the multiplication by means of
1369 approriate conversion.
1371 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1373 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
1374 the in-place initialization aggregate created for pragmas
1375 Initialize_Scalars or Normalize_Scalars is performed with checks
1378 2018-05-25 Arnaud Charlet <charlet@adacore.com>
1380 * exp_aggr.adb (Convert_To_Positional): Bump default for
1381 Max_Others_Replicate to 32. Update comments.
1382 * osint.ads (Unknown_Attributes): No longer pretend this is a constant.
1383 (No_File_Info_Cache): Initialize separately.

1388 * sem_res.adb (Resolve_Membership_Op): Allow the use of the membership
1389 test when the left operand is a class-wide interface and the right
1390 operand is not a class-wide type.
1391 * exp_ch4.adb (Tagged_Membership): Adding support for interface as the
1394 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1396 * exp_aggr.adb (Flatten): A quantified expression cannot be duplicated

1402 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1404 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
1405 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
1406 into three distring cases rather than in one loop which attempts to
1407 handle all three cases. This rewrite eliminates an issue where the last
1408 frame of the stack cannot be freed, thus causing the memory range of a
1409 new frame to approach the overflow point of the memory index type.
1410 Since the overflow is logically treated as a
1411 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
1412 (SS_Allocate_Static): New routine. The routine factorizes the static
1413 secondary stack-related code from the former SS_Allocate.
1415 2018-05-25 Sergey Rybin <rybin@adacore.com>
1417 * doc/gnat_ugn/gnat_and_program_execution.rst: Add description of '-U'
1418 option for gnatelim.
1420 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1422 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
1423 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
1424 is created when the proper body of the stub is analyzed.
1425 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
1426 is the proper body of a subunit, the cloned body must be inserted in
1427 the declarative list that contains the stub.
1429 2018-05-25 Justin Squirek <squirek@adacore.com>
1431 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
1432 generate code for 6.5(8-10) so that we don't get an assertion error
1433 when dealing with an incomplete return type.
1435 2018-05-25 Arnaud Charlet <charlet@adacore.com>
1437 * pprint.adb (Expression_Name): Strip too long expressions to avoid
1438 carrying very large strings.

1442 * switch-b.adb (Scan_Binder_Switches): binder switch -Q accepts Natural

1464 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1466 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
1467 Validate_Derived_Type_Instance, to verify that all interfaces
1468 implemented by the formal type are also implemented by the actual. The
1469 verification is complicated when an interface of the formal is declared
1470 in a generic unit and the actual is declared in an instance of it.
1471 There is currently no mechanism to relate an interface declared within
1472 a generic to the corresponding interface in an instance, so we must
1473 traverse the list of interfaces of the actual, looking for a name
1474 match, and verifying that that interface is declared in an instance.
1476 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
1478 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra
1479 assertions; replace function versions of Next_Formal/Next_Actual with
1480 their procedural versions (which are more concise).

1515 * libgnat/i-cexten.ads (bool): Change to boolean with convention C.
1516 * gcc-interface/decl.c (gnat_to_gnu_entity): Add new local variable

1518 <E_Enumeration_Type>: Set precision 1 on boolean types with foreign
1520 <E_Enumeration_Subtype>: Likewise for subtypes.
1521 <E_Record_Type>: Force the size of a storage unit on empty classes.
1522 * gcc-interface/utils.c (make_type_from_size) <BOOLEAN_TYPE>: Skip
1523 boolean types with precision 1 if the size is the expected one.

1541 prefixes of array attributes, to prefixes that are entity names whose
1542 type is constrained.
1543 (Note_Uplevel_Bound): Verify that the bound is declared in an enclosing

2710 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
2711 delegate the secondary stack management when there is no suitable
2712 transient context, and the transient scope was intended to manage the

2717 the comment on usage.
2718 (Find_Transient_Context): Change the initinte loop into a while loop.

3032 2018-01-11 Yannick Moy <moy@adacore.com>
3034 * doc/gnat_rm/standard_and_implementation_defined_restrictions.rst:
3035 Update description of restriction SPARK_05 with SPARK 2014.
3036 * gnat_rm.texi: Regenerate.
3038 2018-01-11 Vasiliy Fofanov <fofanov@adacore.com>
3040 * doc/gnat_ugn/gnat_utility_programs.rst: Fix layout.
3042 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3044 * exp_aggr.adb, exp_ch9.adb, exp_util.adb, sem_aggr.adb, sem_ch3.adb,
3045 sem_res.adb, sem_util.adb: Minor reformatting.
3047 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3049 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
3050 has a delayed aspect which must be processed at the point the type is
3051 frozen. This mimics what is done when the predicate is provided by a
3054 2018-01-11 Doug Rupp <rupp@adacore.com>
3056 * init.c (vxworks): Add macro checks for __aarch64__.
3058 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3060 * exp_util.adb (Add_Failure_Expression): New routine.
3061 (Make_Predicate_Check): Reimplement the handling of Predicate_Failure.
3062 * sem_util.adb (Is_Current_Instance): Code cleanup.
3064 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
3066 * libgnat/s-parame*.adb, libgnat/s-parame*.ads: Remove unneeded
3067 Default_Sec_Stack_Size.
3068 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
3069 limit check so that the integer index does not overflow. Check the
3070 dynamic stack allocation does not cause the secondary stack pointer to
3072 (SS_Info): Align colons.
3073 (SS_Init): Cover the case when bootstraping with an old compiler that
3074 does not set Default_SS_Size.
3076 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3078 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
3079 legality of an inherited operation that may require overriding, ignore
3080 primitive_wrappers that correspond to explicit operations that override
3081 an interface primitive.
3082 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
3083 operation to which the class-wide expression applies is a protected op.
3084 with a primitive_wrapper, verify that the updated inherited expression
3085 does not contain an internal call to a protected function. This
3086 completes the implementation of AI12-0166.
3088 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3090 * ali.adb: Document the remaining letters available for ALI lines.
3091 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
3092 * ali.ads: Update type With_Record. Field
3093 Implicit_With_From_Instantiation is no longer in use. Add field
3095 * csinfo.adb (CSinfo): Remove the setup for attribute
3096 Implicit_With_From_Instantiation.
3097 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
3098 either implicitly or explicitly withed.
3099 (Is_Implicit_With_Clause): New routine.
3100 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
3101 confusion with the with clause attribute by the same name.
3102 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
3103 * rtsfind.adb (Maybe_Add_With): Code cleanup.
3104 * sem_ch8.adb (Present_System_Aux): Code cleanup.
3105 * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
3107 (Implicit_With_On_Parent): Mark the with clause as generated for a
3109 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
3110 instantiation are no longer marked as Implicit_With_From_Instantiation
3111 because they are already marked as implicit.
3112 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
3113 which marks implicit with clauses as related to an instantiation.
3114 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
3115 (Parent_With): New routine.
3116 (Set_Implicit_With_From_Instantiation): Removed.
3117 (Set_Parent_With): New routine.
3118 * sinfo.ads: Update the documentation of attribute Implicit_With.
3119 Remove attribute Implicit_With_From_Instantiation along with
3120 occurrences in nodes. Add attribute Parent_With along with occurrences
3122 (Implicit_With_From_Instantiation): Removed along with pragma Inline.
3123 (Parent_With): New routine along with pragma Inline.
3124 (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.
3125 (Set_Parent_With): New routine along with pragma Inline.
3127 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3129 * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
3130 entity when the enclosing construct is a body.
3132 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
3134 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
3135 Secondary_Stack_Size handling as a pragma is now generated for the
3136 corresponding aspect instead of an attribute. Pragma expression is
3137 relocated instead of evaluated. Discriminant of the corresponding
3138 record type is referenced rather than the type discriminant.
3139 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
3140 Secondary_Stack_Size rep item checks to only look for the pragma rep.
3141 * sem_ch13.adb (Analyze_One_Aspect): Transform
3142 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
3143 because the attribute does not have visibility on a task type's
3144 discriminants when the type's definition is expanded.
3145 (Analyze_Attribute_Definition_Clause): Remove handling of
3146 Attribute_Secondary_Stack_Size.
3147 * snames.adb-tmpl, snames.ads-tmpl: Remove
3148 Attribute_Secondary_Stack_Size, no longer used.
3150 2018-01-11 Justin Squirek <squirek@adacore.com>
3152 * sem_ch8.adb: Minor comment fix.
3154 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3156 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
3157 individual action because the action may denote a complex expression,
3158 such as a case statement, which in turn may contain additional
3161 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3163 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
3164 analysis on a copy of the expression with a copy of the index variable,
3165 because full expansion will rewrite construct into a loop with the
3166 original loop variable.
3167 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
3168 expression is an iterated component association. Full analysis takes
3169 place when construct is rewritten as a loop.
3170 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
3171 is not safe for in-place assignment.
3172 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
3173 entity with no homonym and no other entity in the scope.
3175 2018-01-11 Justin Squirek <squirek@adacore.com>
3177 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
3178 message to be printed on the pragma argument identifier.
3180 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3182 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
3183 entity of the generated invariant procedure in order to construct a
3184 proper entity chain.
3186 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
3188 * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
3191 2018-01-11 Arnaud Charlet <charlet@adacore.com>
3193 * einfo.ads, einfo.adb (Activation_Record_Component,
3194 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
3195 Allow E_Discriminant.
3197 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
3199 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
3200 for atomic access once the component size is taken into account and
3201 also do it if the component type is Atomic or Volatile_Full_Access.
3203 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
3205 * gnatvsn.ads: Bump copyright year.

3208 Alan Hayward <alan.hayward@arm.com>
3209 David Sherwood <david.sherwood@arm.com>

3222 Alan Hayward <alan.hayward@arm.com>
3223 David Sherwood <david.sherwood@arm.com>
3225 * gcc-interface/utils.c (gnat_types_compatible_p): Handle
3226 polynomial TYPE_VECTOR_SUBPARTS.
3228 2018-01-03 Richard Sandiford <richard.sandiford@linaro.org>
3229 Alan Hayward <alan.hayward@arm.com>
3230 David Sherwood <david.sherwood@arm.com>

3235 2018-01-03 Jakub Jelinek <jakub@redhat.com>
3237 Update copyright years.
3239 * gnat_ugn.texi: Bump @copying's copyright year.
