914 comment about the memset case.
916 2018-05-30 Bob Duff <duff@adacore.com>
918 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
919 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
920 We need to analyze it as part of analyzing the block, so that if the
921 call to Element that initializes Elmt_Decl returns on the secondary
922 stack, the block will ss_mark/ss_release. This block is inside the
923 loop; we don't want to leak memory until the loop exits. The purpose
924 of analyzing Elmt_Decl first was to catch the error of modifying it,
925 which is illegal because it's a loop parameter. The above causes us to
926 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
927 it on the Element entity, so we end up with an E_Variable node with the
929 * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.
930 * sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop
931 parameter not allowed" error if Is_Loop_Parameter.
932 * sem_util.adb (Is_Variable): Return False if Is_Loop_Parameter, to

949 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
950 a package body that is a compilation unit may contain blocks that
951 declare local subprograms. In Subprogram_Unnesting Mode such
952 subprograms must be handled as nested inside the (implicit) elaboration
953 procedure that executes that statement part. To handle properly uplevel
954 references we construct that subprogram explicitly, to contain blocks
955 and inner subprograms, The statement part of the compilation unit
956 becomes a call to this subprogram. This is only done if blocks are
957 present in the statement list of the body.

1263 * exp_unst.adb (Visit_Node): For indexed components and attribute
1264 references, examine index expressions or associated expressions as well
1265 to record uplevel references.
1266 (Vist_Node): For function and procedure calls, if a formal is an
1267 unconstrained array and the actual is constrained, check whether bounds
1268 of actual have uplevel references.
1270 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1272 * einfo.ads, einfo.adb: Exceptions can be uplevel references, and thus
1273 they can appear as components of activation records.

1280 depends on a discriminant manually instead of using the predicate
1281 Size_Depends_On_Discriminant in the array type case.
1283 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1285 * exp_unst.adb (Check_Static_Type): For a record subtype, check
1286 discriminant constraints as well.
1287 (Visit_Node): For a selected component, check type of prefix, as is
1288 done for indexed components and slices.
1290 2018-05-28 Javier Miranda <miranda@adacore.com>
1292 * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
1293 value when converting a float value to a fixed-point value. This is
1294 required for CCG because it handles fixed-point types by means of
1295 unsigned integer type variables. The range check is now performed using
1296 the integer value stored in this temporary.
1298 2018-05-28 Yannick Moy <moy@adacore.com>
1300 * sem_util.adb (Is_OK_Volatile_Context): Add attributes First, Last and

1320 * exp_ch4.adb (Expand_Composite_Equality): For a composite (or FP)
1321 component type, do not expand array equality using the unconstrained
1322 base type, except for the case where the bounds of the type depend on a
1325 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1327 * einfo.ads, einfo.adb (Needs_Activation_Record): New flag on
1328 access-to-subprogram types, to indicate that an indirect call through
1329 such a type requires an activation record when compiling for LLVM.
1330 * sem_ch3.adb (Access_Subprogram_Declaration): Set new flag as needed.
1332 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1334 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
1335 when bounds of fixed type are static, to remove some spuerfluous
1336 implicit conversions and provide an accurate result when converting
1337 back and forth between the fixed point type and a floating point type.
1339 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1341 * exp_unst.adb (Unnest_Subprogram): Prevent creation of empty
1344 2018-05-28 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
1346 * exp_unst.adb (Check_Static_Type): Add argument to indicate node to be
1347 replaced, if any; all callers changed.
1348 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
1349 constant with private view so we take the address of that entity.
1350 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
1351 any; all callers changed. Handle N_Indexed_Component like
1352 N_Attribute_Reference. Add N_Type_Conversion case.
1353 (Visit_Node): Indexed references can be uplevel if the type isn't
1355 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
1356 been relocated, set first_named pointer in original node as well.
1358 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1360 * exp_aggr.adb (Flatten): Copy tree of expression in a component
1361 association with a range or a set of discrete choices, rather than
1362 relocating the node. This avoids inconsistencies in the tree when
1363 handling nested subprograms with uplevel references for LLVM.

1418 * sem_prag.adb (Process_Atomic_Independent_Shared_Volatile): Include
1419 the declarations of single concurrent types because they fall in the
1420 category of full type and object declarations.

1427 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1429 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
1430 includes a call to function to which it applies. This may mean an
1431 omission of an attribute reference 'Result, in particular if the
1432 function is pqrameterless.
1434 2018-05-28 Justin Squirek <squirek@adacore.com>

1448 * repinfo.adb (List_Array_Info): Start with an explicit blank line and
1449 end with the linker section, if any.
1450 (List_Entities): Do not output the linker section for record types,
1451 array types and variables.
1452 (Print_Expr): Factor out common processing for unary operators and
1453 special values. Adjust and reorder the various cases.
1454 (List_Object_Info): End with the linker section, if any.
1455 (List_Record_Info): Likewise.
1456 (List_Type_Info): Do not start with a blank line.
1458 2018-05-25 Nicolas Roche <roche@adacore.com>
1460 * libgnat/s-valrea.adb (Scan_Real): Abort computation once it is sure
1461 that the result will be either -infinite or +infinite.
1463 2018-05-25 Patrick Bernardi <bernardi@adacore.com>
1465 * libgnat/s-parame.ads, libgnat/s-parame__vxworks.ads,
1466 libgnat/s-parame__ae653.ads, libgnat/s-parame__hpux.ads (Size_Type):
1467 Expand range of type to match the address space of the target.
1468 (Task_Storage_Size): Remove unused type.
1470 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1472 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
1473 of a fixed point type and the parent is a multiplying operation,
1474 resolve the operand with its own type because the context will impose a
1475 resulting type on the result of the multiplication by means of
1476 approriate conversion.
1478 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1480 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
1481 the in-place initialization aggregate created for pragmas
1482 Initialize_Scalars or Normalize_Scalars is performed with checks
1485 2018-05-25 Arnaud Charlet <charlet@adacore.com>
1487 * exp_aggr.adb (Convert_To_Positional): Bump default for
1488 Max_Others_Replicate to 32. Update comments.
1489 * osint.ads (Unknown_Attributes): No longer pretend this is a constant.
1490 (No_File_Info_Cache): Initialize separately.

1501 2018-05-25 Ed Schonberg <schonberg@adacore.com>

1509 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1511 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
1512 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
1513 into three distring cases rather than in one loop which attempts to
1514 handle all three cases. This rewrite eliminates an issue where the last
1515 frame of the stack cannot be freed, thus causing the memory range of a
1516 new frame to approach the overflow point of the memory index type.
1517 Since the overflow is logically treated as a
1518 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
1519 (SS_Allocate_Static): New routine. The routine factorizes the static
1520 secondary stack-related code from the former SS_Allocate.
1522 2018-05-25 Sergey Rybin <rybin@adacore.com>
1524 * doc/gnat_ugn/gnat_and_program_execution.rst: Add description of '-U'
1525 option for gnatelim.
1527 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1529 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
1530 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
1531 is created when the proper body of the stub is analyzed.
1532 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
1533 is the proper body of a subunit, the cloned body must be inserted in
1534 the declarative list that contains the stub.
1536 2018-05-25 Justin Squirek <squirek@adacore.com>
1538 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
1539 generate code for 6.5(8-10) so that we don't get an assertion error
1540 when dealing with an incomplete return type.
1542 2018-05-25 Arnaud Charlet <charlet@adacore.com>
1544 * pprint.adb (Expression_Name): Strip too long expressions to avoid
1545 carrying very large strings.

1573 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
1574 Validate_Derived_Type_Instance, to verify that all interfaces
1575 implemented by the formal type are also implemented by the actual. The
1576 verification is complicated when an interface of the formal is declared
1577 in a generic unit and the actual is declared in an instance of it.
1578 There is currently no mechanism to relate an interface declared within
1579 a generic to the corresponding interface in an instance, so we must
1580 traverse the list of interfaces of the actual, looking for a name
1581 match, and verifying that that interface is declared in an instance.

3033 (Make_Build_In_Place_Call_In_Object_Declaration): Update the call to
3034 Establish_Transient_Scope.
3035 * exp_ch7.adb (Establish_Transient_Scope): Restructured. Delegate the
3036 management of the secondary stack to an enclosing scope if there is no
3037 suitable construct to wrap, and the transient scope was intended to
3038 manage the secondary stack.
3039 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
3040 is a valid boundary for a transient expression which comes from the
3041 statements of the alternative, otherwise alternatives cannot be
3042 wrapped. Assignments of controlled objects which have controlled
3043 actions suppressed now stop the traversal as there is no point in
3044 looking for an enclosing construct. Add several N_xxx_Body choices to
3045 the termination conditions for completeness.
3046 * exp_ch7.ads (Establish_Transient_Scope): Update the parameter profile
3047 and the associated comment on usage.
3048 * exp_smem.adb (Add_Shared_Var_Lock_Procs): Update the call to
3049 Establish_Transient_Scope.
3050 (Add_Write_After): Update the call to Establish_Transient_Scope.
3051 * sem_res.adb (Check_Initialization_Call): Removed.
3052 (Resolve_Actuals): Account for additional cases where finalization
3053 actions are required by utilizing predicate Needs_Finalization rather
3055 (Resolve_Call): Type initialization procedures can now utilize
3056 transient scopes to manage the secondary stack, thus preventing leaks
3057 during initialization. Remove the previous kludgy algorithm which
3058 attempts to manage the secondary stack at the object creation site.
3060 2018-01-11 Jerome Lambourg <lambourg@adacore.com>
3062 * libgnat/g-soliop__qnx.ads: New.

3099 * gnat_rm.texi: Regenerate.
3101 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3103 * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
3104 formsl type corresponding to the actual fixed point type is private,
3105 because in this case there can be no suspicious arithmetic operations
3106 in the generic unless they reference a formal subprogram. Clarify
3109 2018-01-11 Javier Miranda <miranda@adacore.com>
3111 * exp_util.adb (Remove_Side_Effects): No action done for functions
3112 returning class-wide types since it requires generating code using
3113 'reference and the CCG target has no secondary stack.
3114 * gnat1drv.adb: Disable building static dispatch tables when generating
3117 2018-01-11 Piotr Trojanek <trojanek@adacore.com>

3121 (File_Type): Add Default_Initial_Condition aspect.
3123 2018-01-11 Pascal Obry <obry@adacore.com>
3125 * libgnat/s-os_lib.adb (Normalize_Pathname): New implementation.
3127 2018-01-11 Bob Duff <duff@adacore.com>
3129 * doc/gnat_ugn/gnat_utility_programs.rst: Rewrite gnatpp documentation
3130 to match what the Libadalang-based version does.
3131 * doc/gnat_ugn/about_this_guide.rst: Update reference.
3133 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3135 * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
3136 if it contains at least one component declaration employing a function
3137 call returning on the secondary stack.
3139 2018-01-11 Yannick Moy <moy@adacore.com>
3141 * doc/gnat_rm/standard_and_implementation_defined_restrictions.rst:
3142 Update description of restriction SPARK_05 with SPARK 2014.

3151 * exp_aggr.adb, exp_ch9.adb, exp_util.adb, sem_aggr.adb, sem_ch3.adb,
3152 sem_res.adb, sem_util.adb: Minor reformatting.
3154 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3156 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
3157 has a delayed aspect which must be processed at the point the type is
3158 frozen. This mimics what is done when the predicate is provided by a
3161 2018-01-11 Doug Rupp <rupp@adacore.com>
3163 * init.c (vxworks): Add macro checks for __aarch64__.
3165 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3167 * exp_util.adb (Add_Failure_Expression): New routine.
3168 (Make_Predicate_Check): Reimplement the handling of Predicate_Failure.
3169 * sem_util.adb (Is_Current_Instance): Code cleanup.
3171 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
3173 * libgnat/s-parame*.adb, libgnat/s-parame*.ads: Remove unneeded
3174 Default_Sec_Stack_Size.
3175 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
3176 limit check so that the integer index does not overflow. Check the
3177 dynamic stack allocation does not cause the secondary stack pointer to
3179 (SS_Info): Align colons.
3180 (SS_Init): Cover the case when bootstraping with an old compiler that
3181 does not set Default_SS_Size.
3183 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3185 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
3186 legality of an inherited operation that may require overriding, ignore
3187 primitive_wrappers that correspond to explicit operations that override
3188 an interface primitive.
3189 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
3190 operation to which the class-wide expression applies is a protected op.
3191 with a primitive_wrapper, verify that the updated inherited expression
3192 does not contain an internal call to a protected function. This
3193 completes the implementation of AI12-0166.
3195 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3197 * ali.adb: Document the remaining letters available for ALI lines.
3198 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
3199 * ali.ads: Update type With_Record. Field
3200 Implicit_With_From_Instantiation is no longer in use. Add field
3202 * csinfo.adb (CSinfo): Remove the setup for attribute
3203 Implicit_With_From_Instantiation.
3204 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
3205 either implicitly or explicitly withed.
3206 (Is_Implicit_With_Clause): New routine.
3207 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
3208 confusion with the with clause attribute by the same name.
3209 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
3210 * rtsfind.adb (Maybe_Add_With): Code cleanup.
3211 * sem_ch8.adb (Present_System_Aux): Code cleanup.
3212 * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
3214 (Implicit_With_On_Parent): Mark the with clause as generated for a
3216 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
3217 instantiation are no longer marked as Implicit_With_From_Instantiation
3218 because they are already marked as implicit.
3219 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
3220 which marks implicit with clauses as related to an instantiation.
3221 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
3222 (Parent_With): New routine.
3223 (Set_Implicit_With_From_Instantiation): Removed.
3224 (Set_Parent_With): New routine.
3225 * sinfo.ads: Update the documentation of attribute Implicit_With.
3226 Remove attribute Implicit_With_From_Instantiation along with
3227 occurrences in nodes. Add attribute Parent_With along with occurrences
3229 (Implicit_With_From_Instantiation): Removed along with pragma Inline.
3230 (Parent_With): New routine along with pragma Inline.
3231 (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.
3232 (Set_Parent_With): New routine along with pragma Inline.
3234 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3236 * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
3237 entity when the enclosing construct is a body.
3239 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
3241 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
3242 Secondary_Stack_Size handling as a pragma is now generated for the
3243 corresponding aspect instead of an attribute. Pragma expression is
3244 relocated instead of evaluated. Discriminant of the corresponding
3245 record type is referenced rather than the type discriminant.
3246 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
3247 Secondary_Stack_Size rep item checks to only look for the pragma rep.
3248 * sem_ch13.adb (Analyze_One_Aspect): Transform
3249 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
3250 because the attribute does not have visibility on a task type's
3251 discriminants when the type's definition is expanded.
3252 (Analyze_Attribute_Definition_Clause): Remove handling of
3253 Attribute_Secondary_Stack_Size.
3254 * snames.adb-tmpl, snames.ads-tmpl: Remove
3255 Attribute_Secondary_Stack_Size, no longer used.
3257 2018-01-11 Justin Squirek <squirek@adacore.com>

3261 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3263 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
3264 individual action because the action may denote a complex expression,
3265 such as a case statement, which in turn may contain additional
3268 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3270 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
3271 analysis on a copy of the expression with a copy of the index variable,
3272 because full expansion will rewrite construct into a loop with the
3273 original loop variable.
3274 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
3275 expression is an iterated component association. Full analysis takes
3276 place when construct is rewritten as a loop.
3277 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
3278 is not safe for in-place assignment.
3279 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
3280 entity with no homonym and no other entity in the scope.
3282 2018-01-11 Justin Squirek <squirek@adacore.com>
3284 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
3285 message to be printed on the pragma argument identifier.
3287 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3289 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
3290 entity of the generated invariant procedure in order to construct a
3291 proper entity chain.
3293 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
3295 * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
3298 2018-01-11 Arnaud Charlet <charlet@adacore.com>
3300 * einfo.ads, einfo.adb (Activation_Record_Component,
3301 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
3302 Allow E_Discriminant.
3304 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
3306 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
3307 for atomic access once the component size is taken into account and
3308 also do it if the component type is Atomic or Volatile_Full_Access.
3310 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
3312 * gnatvsn.ads: Bump copyright year.
