933 comment about the memset case.
935 2018-05-30 Bob Duff <duff@adacore.com>
937 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
938 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
939 We need to analyze it as part of analyzing the block, so that if the
940 call to Element that initializes Elmt_Decl returns on the secondary
941 stack, the block will ss_mark/ss_release. This block is inside the
942 loop; we don't want to leak memory until the loop exits. The purpose
943 of analyzing Elmt_Decl first was to catch the error of modifying it,
944 which is illegal because it's a loop parameter. The above causes us to
945 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
946 it on the Element entity, so we end up with an E_Variable node with the
948 * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.
949 * sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop
950 parameter not allowed" error if Is_Loop_Parameter.
951 * sem_util.adb (Is_Variable): Return False if Is_Loop_Parameter, to

968 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
969 a package body that is a compilation unit may contain blocks that
970 declare local subprograms. In Subprogram_Unnesting Mode such
971 subprograms must be handled as nested inside the (implicit) elaboration
972 procedure that executes that statement part. To handle properly uplevel
973 references we construct that subprogram explicitly, to contain blocks
974 and inner subprograms, The statement part of the compilation unit
975 becomes a call to this subprogram. This is only done if blocks are
976 present in the statement list of the body.

1063 * exp_ch6.adb (Expand_N_Subprogram_Body): Do not generate push/pop for
1064 exceptions if subprogram unnesting is in effect, because these branch
1065 nodes are relevant only in the presence of nested subprograms.

1282 * exp_unst.adb (Visit_Node): For indexed components and attribute
1283 references, examine index expressions or associated expressions as well
1284 to record uplevel references.
1285 (Vist_Node): For function and procedure calls, if a formal is an
1286 unconstrained array and the actual is constrained, check whether bounds
1287 of actual have uplevel references.
1289 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1291 * einfo.ads, einfo.adb: Exceptions can be uplevel references, and thus
1292 they can appear as components of activation records.

1302 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1304 * exp_unst.adb (Check_Static_Type): For a record subtype, check
1305 discriminant constraints as well.
1306 (Visit_Node): For a selected component, check type of prefix, as is
1307 done for indexed components and slices.
1309 2018-05-28 Javier Miranda <miranda@adacore.com>
1311 * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
1312 value when converting a float value to a fixed-point value. This is
1313 required for CCG because it handles fixed-point types by means of
1314 unsigned integer type variables. The range check is now performed using
1315 the integer value stored in this temporary.
1317 2018-05-28 Yannick Moy <moy@adacore.com>
1319 * sem_util.adb (Is_OK_Volatile_Context): Add attributes First, Last and

1339 * exp_ch4.adb (Expand_Composite_Equality): For a composite (or FP)
1340 component type, do not expand array equality using the unconstrained
1341 base type, except for the case where the bounds of the type depend on a
1344 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1346 * einfo.ads, einfo.adb (Needs_Activation_Record): New flag on
1347 access-to-subprogram types, to indicate that an indirect call through
1348 such a type requires an activation record when compiling for LLVM.
1349 * sem_ch3.adb (Access_Subprogram_Declaration): Set new flag as needed.
1351 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1353 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
1354 when bounds of fixed type are static, to remove some spuerfluous
1355 implicit conversions and provide an accurate result when converting
1356 back and forth between the fixed point type and a floating point type.

1360 * exp_unst.adb (Unnest_Subprogram): Prevent creation of empty
1363 2018-05-28 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
1365 * exp_unst.adb (Check_Static_Type): Add argument to indicate node to be
1366 replaced, if any; all callers changed.
1367 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
1368 constant with private view so we take the address of that entity.
1369 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
1370 any; all callers changed. Handle N_Indexed_Component like
1371 N_Attribute_Reference. Add N_Type_Conversion case.
1372 (Visit_Node): Indexed references can be uplevel if the type isn't
1374 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
1375 been relocated, set first_named pointer in original node as well.
1377 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1379 * exp_aggr.adb (Flatten): Copy tree of expression in a component
1380 association with a range or a set of discrete choices, rather than
1381 relocating the node. This avoids inconsistencies in the tree when
1382 handling nested subprograms with uplevel references for LLVM.

1437 * sem_prag.adb (Process_Atomic_Independent_Shared_Volatile): Include
1438 the declarations of single concurrent types because they fall in the
1439 category of full type and object declarations.

1446 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1448 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
1449 includes a call to function to which it applies. This may mean an
1450 omission of an attribute reference 'Result, in particular if the
1451 function is pqrameterless.
1453 2018-05-28 Justin Squirek <squirek@adacore.com>

1468 end with the linker section, if any.
1469 (List_Entities): Do not output the linker section for record types,
1470 array types and variables.
1471 (Print_Expr): Factor out common processing for unary operators and
1472 special values. Adjust and reorder the various cases.
1473 (List_Object_Info): End with the linker section, if any.
1474 (List_Record_Info): Likewise.
1475 (List_Type_Info): Do not start with a blank line.
1477 2018-05-25 Nicolas Roche <roche@adacore.com>
1479 * libgnat/s-valrea.adb (Scan_Real): Abort computation once it is sure
1480 that the result will be either -infinite or +infinite.
1482 2018-05-25 Patrick Bernardi <bernardi@adacore.com>
1484 * libgnat/s-parame.ads, libgnat/s-parame__vxworks.ads,

1486 Expand range of type to match the address space of the target.
1487 (Task_Storage_Size): Remove unused type.
1489 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1491 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
1492 of a fixed point type and the parent is a multiplying operation,
1493 resolve the operand with its own type because the context will impose a
1494 resulting type on the result of the multiplication by means of
1495 approriate conversion.
1497 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1499 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
1500 the in-place initialization aggregate created for pragmas
1501 Initialize_Scalars or Normalize_Scalars is performed with checks
1504 2018-05-25 Arnaud Charlet <charlet@adacore.com>
1506 * exp_aggr.adb (Convert_To_Positional): Bump default for
1507 Max_Others_Replicate to 32. Update comments.
1508 * osint.ads (Unknown_Attributes): No longer pretend this is a constant.
1509 (No_File_Info_Cache): Initialize separately.

1528 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1530 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
1531 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
1532 into three distring cases rather than in one loop which attempts to
1533 handle all three cases. This rewrite eliminates an issue where the last
1534 frame of the stack cannot be freed, thus causing the memory range of a
1535 new frame to approach the overflow point of the memory index type.
1536 Since the overflow is logically treated as a
1537 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
1538 (SS_Allocate_Static): New routine. The routine factorizes the static
1539 secondary stack-related code from the former SS_Allocate.
1541 2018-05-25 Sergey Rybin <rybin@adacore.com>
1543 * doc/gnat_ugn/gnat_and_program_execution.rst: Add description of '-U'
1544 option for gnatelim.
1546 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1548 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
1549 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
1550 is created when the proper body of the stub is analyzed.
1551 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
1552 is the proper body of a subunit, the cloned body must be inserted in
1553 the declarative list that contains the stub.

1592 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
1593 Validate_Derived_Type_Instance, to verify that all interfaces
1594 implemented by the formal type are also implemented by the actual. The

1596 in a generic unit and the actual is declared in an instance of it.
1597 There is currently no mechanism to relate an interface declared within
1598 a generic to the corresponding interface in an instance, so we must
1599 traverse the list of interfaces of the actual, looking for a name
1600 match, and verifying that that interface is declared in an instance.

2046 a constrained array component.
2047 * einfo.adb: Subprograms for Predicated_Parent.
2048 (Predicate_Function): Use new attribute.
2049 * exp_util.adb (Make_Predicate_Call): If the predicate function is not
2050 available for a subtype, retrieve it from the base type, which may have
2051 been frozen after the subtype declaration and not captured by the
2052 subtype declaration.

2169 * sem_ch5.adb (Preanalyze_Range): The pre-analysis of the domain of
2170 iteration of an Ada2012 loop is performed to determine the type of the
2171 domain, but full analysis is performed once the loop is rewritten as a
2172 while-loop during expansion. The pre-analysis suppresses expansion; it
2173 must also suppress the generation of freeze nodes, which may otherwise
2174 appear in the wrong scope before rewritting.

3035 * sem_ch10.adb (Check_Private_Child_Unit): Ensure that the enclosing
3036 scope of package Ada is Standard.
3038 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3040 * sem_ch13.adb (Replace_Type_Ref): Handle properly reference to a
3041 subcomponent of the current entity when building the body for a dynamic
3042 predicate function for a record with composite subcomponents.
3044 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3046 * exp_aggr.adb (Convert_Aggr_In_Object_Decl): Update the call to
3047 Establish_Transient_Scope.
3048 (Convert_To_Assignments): Update the call to Establish_Transient_Scope.
3049 (Expand_Array_Aggregate): Update the call to Establish_Transient_Scope.
3050 * exp_ch6.adb (Expand_Call_Helper): Update the call to
3051 Establish_Transient_Scope.
3052 (Make_Build_In_Place_Call_In_Object_Declaration): Update the call to
3053 Establish_Transient_Scope.
3054 * exp_ch7.adb (Establish_Transient_Scope): Restructured. Delegate the
3055 management of the secondary stack to an enclosing scope if there is no
3056 suitable construct to wrap, and the transient scope was intended to
3057 manage the secondary stack.
3058 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
3059 is a valid boundary for a transient expression which comes from the
3060 statements of the alternative, otherwise alternatives cannot be
3061 wrapped. Assignments of controlled objects which have controlled
3062 actions suppressed now stop the traversal as there is no point in
3063 looking for an enclosing construct. Add several N_xxx_Body choices to
3064 the termination conditions for completeness.
3065 * exp_ch7.ads (Establish_Transient_Scope): Update the parameter profile
3066 and the associated comment on usage.
3067 * exp_smem.adb (Add_Shared_Var_Lock_Procs): Update the call to
3068 Establish_Transient_Scope.
3069 (Add_Write_After): Update the call to Establish_Transient_Scope.
3070 * sem_res.adb (Check_Initialization_Call): Removed.
3071 (Resolve_Actuals): Account for additional cases where finalization
3072 actions are required by utilizing predicate Needs_Finalization rather
3074 (Resolve_Call): Type initialization procedures can now utilize
3075 transient scopes to manage the secondary stack, thus preventing leaks
3076 during initialization. Remove the previous kludgy algorithm which
3077 attempts to manage the secondary stack at the object creation site.
3079 2018-01-11 Jerome Lambourg <lambourg@adacore.com>
3081 * libgnat/g-soliop__qnx.ads: New.
3082 * adaint.c, adaint.h, cstreams.c, s-oscons-tmplt.c, sysdep.c: Update
3085 2018-01-11 Bob Duff <duff@adacore.com>

3088 a null procedure occurs in a protected definition.
3090 2018-01-11 Bob Duff <duff@adacore.com>
3092 * binderr.ads, namet.ads: Minor reformatting.
3094 2018-01-11 Bob Duff <duff@adacore.com>

3104 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3106 * sem_ch6.adb (Freeze_Expr_Types): If an access value is the
3107 controlling argument of a dispatching call. freeze the corresponding
3110 2018-01-11 Ben Brosgol <brosgol@adacore.com>
3112 * doc/Makefile: Add Sphinx option -W to treat warnings as errors.
3114 2018-01-11 Ben Brosgol <brosgol@adacore.com>
3116 * doc/gnat_rm/implementation_defined_aspects.rst: Minor type/wording
3118 * gnat_rm.texi: Regenerate.
3120 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3122 * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
3123 formsl type corresponding to the actual fixed point type is private,
3124 because in this case there can be no suspicious arithmetic operations
3125 in the generic unless they reference a formal subprogram. Clarify
3128 2018-01-11 Javier Miranda <miranda@adacore.com>
3130 * exp_util.adb (Remove_Side_Effects): No action done for functions
3131 returning class-wide types since it requires generating code using
3132 'reference and the CCG target has no secondary stack.
3133 * gnat1drv.adb: Disable building static dispatch tables when generating
3136 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
3138 * libgnat/a-direio.ads, libgnat/a-sequio.ads, libgnat/a-ststio.ads,
3139 libgnat/a-textio.ads, libgnat/a-witeio.ads, libgnat/a-ztexio.ads
3140 (File_Type): Add Default_Initial_Condition aspect.
3142 2018-01-11 Pascal Obry <obry@adacore.com>
3144 * libgnat/s-os_lib.adb (Normalize_Pathname): New implementation.
3146 2018-01-11 Bob Duff <duff@adacore.com>
3148 * doc/gnat_ugn/gnat_utility_programs.rst: Rewrite gnatpp documentation
3149 to match what the Libadalang-based version does.
3150 * doc/gnat_ugn/about_this_guide.rst: Update reference.
3152 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3154 * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
3155 if it contains at least one component declaration employing a function
3156 call returning on the secondary stack.
3158 2018-01-11 Yannick Moy <moy@adacore.com>
3160 * doc/gnat_rm/standard_and_implementation_defined_restrictions.rst:
3161 Update description of restriction SPARK_05 with SPARK 2014.
3162 * gnat_rm.texi: Regenerate.
3164 2018-01-11 Vasiliy Fofanov <fofanov@adacore.com>
3166 * doc/gnat_ugn/gnat_utility_programs.rst: Fix layout.
3168 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3170 * exp_aggr.adb, exp_ch9.adb, exp_util.adb, sem_aggr.adb, sem_ch3.adb,
3171 sem_res.adb, sem_util.adb: Minor reformatting.
3173 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3175 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
3176 has a delayed aspect which must be processed at the point the type is
3177 frozen. This mimics what is done when the predicate is provided by a
3180 2018-01-11 Doug Rupp <rupp@adacore.com>
3182 * init.c (vxworks): Add macro checks for __aarch64__.
3184 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3186 * exp_util.adb (Add_Failure_Expression): New routine.
3187 (Make_Predicate_Check): Reimplement the handling of Predicate_Failure.
3188 * sem_util.adb (Is_Current_Instance): Code cleanup.
3190 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
3192 * libgnat/s-parame*.adb, libgnat/s-parame*.ads: Remove unneeded
3193 Default_Sec_Stack_Size.
3194 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
3195 limit check so that the integer index does not overflow. Check the
3196 dynamic stack allocation does not cause the secondary stack pointer to
3198 (SS_Info): Align colons.
3199 (SS_Init): Cover the case when bootstraping with an old compiler that
3200 does not set Default_SS_Size.
3202 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3204 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
3205 legality of an inherited operation that may require overriding, ignore
3206 primitive_wrappers that correspond to explicit operations that override
3207 an interface primitive.
3208 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
3209 operation to which the class-wide expression applies is a protected op.
3210 with a primitive_wrapper, verify that the updated inherited expression
3211 does not contain an internal call to a protected function. This
3212 completes the implementation of AI12-0166.
3214 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3216 * ali.adb: Document the remaining letters available for ALI lines.
3217 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
3218 * ali.ads: Update type With_Record. Field
3219 Implicit_With_From_Instantiation is no longer in use. Add field
3221 * csinfo.adb (CSinfo): Remove the setup for attribute
3222 Implicit_With_From_Instantiation.
3223 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
3224 either implicitly or explicitly withed.
3225 (Is_Implicit_With_Clause): New routine.
3226 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
3227 confusion with the with clause attribute by the same name.
3228 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
3229 * rtsfind.adb (Maybe_Add_With): Code cleanup.
3230 * sem_ch8.adb (Present_System_Aux): Code cleanup.
3231 * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
3233 (Implicit_With_On_Parent): Mark the with clause as generated for a
3235 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
3236 instantiation are no longer marked as Implicit_With_From_Instantiation
3237 because they are already marked as implicit.
3238 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
3239 which marks implicit with clauses as related to an instantiation.
3240 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
3241 (Parent_With): New routine.
3242 (Set_Implicit_With_From_Instantiation): Removed.
3243 (Set_Parent_With): New routine.
3244 * sinfo.ads: Update the documentation of attribute Implicit_With.
3245 Remove attribute Implicit_With_From_Instantiation along with
3246 occurrences in nodes. Add attribute Parent_With along with occurrences
3248 (Implicit_With_From_Instantiation): Removed along with pragma Inline.
3249 (Parent_With): New routine along with pragma Inline.
3250 (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.
3251 (Set_Parent_With): New routine along with pragma Inline.
3253 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3255 * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
3256 entity when the enclosing construct is a body.
3258 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
3260 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
3261 Secondary_Stack_Size handling as a pragma is now generated for the
3262 corresponding aspect instead of an attribute. Pragma expression is
3263 relocated instead of evaluated. Discriminant of the corresponding
3264 record type is referenced rather than the type discriminant.
3265 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
3266 Secondary_Stack_Size rep item checks to only look for the pragma rep.
3267 * sem_ch13.adb (Analyze_One_Aspect): Transform
3268 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
3269 because the attribute does not have visibility on a task type's
3270 discriminants when the type's definition is expanded.
3271 (Analyze_Attribute_Definition_Clause): Remove handling of
3272 Attribute_Secondary_Stack_Size.
3273 * snames.adb-tmpl, snames.ads-tmpl: Remove
3274 Attribute_Secondary_Stack_Size, no longer used.
3276 2018-01-11 Justin Squirek <squirek@adacore.com>
3278 * sem_ch8.adb: Minor comment fix.
3280 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3282 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
3283 individual action because the action may denote a complex expression,
3284 such as a case statement, which in turn may contain additional
3287 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3289 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
3290 analysis on a copy of the expression with a copy of the index variable,
3291 because full expansion will rewrite construct into a loop with the
3292 original loop variable.
3293 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
3294 expression is an iterated component association. Full analysis takes
3295 place when construct is rewritten as a loop.
3296 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
3297 is not safe for in-place assignment.
3298 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
3299 entity with no homonym and no other entity in the scope.
3301 2018-01-11 Justin Squirek <squirek@adacore.com>
3303 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
3304 message to be printed on the pragma argument identifier.
3306 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3308 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
3309 entity of the generated invariant procedure in order to construct a
3310 proper entity chain.
3312 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
3314 * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
3317 2018-01-11 Arnaud Charlet <charlet@adacore.com>
3319 * einfo.ads, einfo.adb (Activation_Record_Component,
3320 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
3321 Allow E_Discriminant.
3323 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
3325 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
3326 for atomic access once the component size is taken into account and
3327 also do it if the component type is Atomic or Volatile_Full_Access.
3329 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
3331 * gnatvsn.ads: Bump copyright year.
