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

973 2018-05-30 Ed Schonberg <schonberg@adacore.com>
975 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
976 a package body that is a compilation unit may contain blocks that
977 declare local subprograms. In Subprogram_Unnesting Mode such
978 subprograms must be handled as nested inside the (implicit) elaboration
979 procedure that executes that statement part. To handle properly uplevel
980 references we construct that subprogram explicitly, to contain blocks
981 and inner subprograms, The statement part of the compilation unit
982 becomes a call to this subprogram. This is only done if blocks are
983 present in the statement list of the body.

1290 references, examine index expressions or associated expressions as well
1291 to record uplevel references.

1294 of actual have uplevel references.
1296 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1298 * einfo.ads, einfo.adb: Exceptions can be uplevel references, and thus

1311 * exp_unst.adb (Check_Static_Type): For a record subtype, check
1312 discriminant constraints as well.
1313 (Visit_Node): For a selected component, check type of prefix, as is
1314 done for indexed components and slices.
1316 2018-05-28 Javier Miranda <miranda@adacore.com>
1318 * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
1319 value when converting a float value to a fixed-point value. This is
1320 required for CCG because it handles fixed-point types by means of
1321 unsigned integer type variables. The range check is now performed using
1322 the integer value stored in this temporary.
1324 2018-05-28 Yannick Moy <moy@adacore.com>

1347 component type, do not expand array equality using the unconstrained
1348 base type, except for the case where the bounds of the type depend on a
1351 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1353 * einfo.ads, einfo.adb (Needs_Activation_Record): New flag on
1354 access-to-subprogram types, to indicate that an indirect call through
1355 such a type requires an activation record when compiling for LLVM.
1356 * sem_ch3.adb (Access_Subprogram_Declaration): Set new flag as needed.
1358 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1360 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
1361 when bounds of fixed type are static, to remove some spuerfluous
1362 implicit conversions and provide an accurate result when converting
1363 back and forth between the fixed point type and a floating point type.

1370 2018-05-28 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
1372 * exp_unst.adb (Check_Static_Type): Add argument to indicate node to be
1373 replaced, if any; all callers changed.
1374 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
1375 constant with private view so we take the address of that entity.
1376 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
1377 any; all callers changed. Handle N_Indexed_Component like
1378 N_Attribute_Reference. Add N_Type_Conversion case.
1379 (Visit_Node): Indexed references can be uplevel if the type isn't
1381 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
1382 been relocated, set first_named pointer in original node as well.
1384 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1386 * exp_aggr.adb (Flatten): Copy tree of expression in a component
1387 association with a range or a set of discrete choices, rather than
1388 relocating the node. This avoids inconsistencies in the tree when
1389 handling nested subprograms with uplevel references for LLVM.

1444 * sem_prag.adb (Process_Atomic_Independent_Shared_Volatile): Include
1445 the declarations of single concurrent types because they fall in the
1446 category of full type and object declarations.

1455 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
1456 includes a call to function to which it applies. This may mean an
1457 omission of an attribute reference 'Result, in particular if the
1458 function is pqrameterless.
1460 2018-05-28 Justin Squirek <squirek@adacore.com>

1474 * repinfo.adb (List_Array_Info): Start with an explicit blank line and
1475 end with the linker section, if any.
1476 (List_Entities): Do not output the linker section for record types,
1477 array types and variables.
1478 (Print_Expr): Factor out common processing for unary operators and
1479 special values. Adjust and reorder the various cases.
1480 (List_Object_Info): End with the linker section, if any.
1481 (List_Record_Info): Likewise.
1482 (List_Type_Info): Do not start with a blank line.
1484 2018-05-25 Nicolas Roche <roche@adacore.com>
1486 * libgnat/s-valrea.adb (Scan_Real): Abort computation once it is sure
1487 that the result will be either -infinite or +infinite.
1489 2018-05-25 Patrick Bernardi <bernardi@adacore.com>
1491 * libgnat/s-parame.ads, libgnat/s-parame__vxworks.ads,

1493 Expand range of type to match the address space of the target.
1494 (Task_Storage_Size): Remove unused type.
1496 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1498 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
1499 of a fixed point type and the parent is a multiplying operation,
1500 resolve the operand with its own type because the context will impose a
1501 resulting type on the result of the multiplication by means of
1502 approriate conversion.
1504 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1506 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
1507 the in-place initialization aggregate created for pragmas
1508 Initialize_Scalars or Normalize_Scalars is performed with checks
1511 2018-05-25 Arnaud Charlet <charlet@adacore.com>
1513 * exp_aggr.adb (Convert_To_Positional): Bump default for
1514 Max_Others_Replicate to 32. Update comments.
1515 * osint.ads (Unknown_Attributes): No longer pretend this is a constant.
1516 (No_File_Info_Cache): Initialize separately.

1535 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1537 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
1538 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
1539 into three distring cases rather than in one loop which attempts to
1540 handle all three cases. This rewrite eliminates an issue where the last
1541 frame of the stack cannot be freed, thus causing the memory range of a
1542 new frame to approach the overflow point of the memory index type.
1543 Since the overflow is logically treated as a
1544 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
1545 (SS_Allocate_Static): New routine. The routine factorizes the static
1546 secondary stack-related code from the former SS_Allocate.
1548 2018-05-25 Sergey Rybin <rybin@adacore.com>
1550 * doc/gnat_ugn/gnat_and_program_execution.rst: Add description of '-U'
1551 option for gnatelim.
1553 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1555 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
1556 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone

1599 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
1600 Validate_Derived_Type_Instance, to verify that all interfaces
1601 implemented by the formal type are also implemented by the actual. The

1603 in a generic unit and the actual is declared in an instance of it.
1604 There is currently no mechanism to relate an interface declared within
1605 a generic to the corresponding interface in an instance, so we must
1606 traverse the list of interfaces of the actual, looking for a name
1607 match, and verifying that that interface is declared in an instance.

2053 a constrained array component.
2054 * einfo.adb: Subprograms for Predicated_Parent.
2055 (Predicate_Function): Use new attribute.
2056 * exp_util.adb (Make_Predicate_Call): If the predicate function is not
2057 available for a subtype, retrieve it from the base type, which may have
2058 been frozen after the subtype declaration and not captured by the
2059 subtype declaration.
2060 * sem_aggr.adb (Resolve_Array_Aggregate): An Others association is
2061 legal within a generated initiqlization procedure, as may happen with a
2062 predicate check on a component, when the predicate function applies to
2063 the base type of the component.
2064 * sem_ch3.adb (Analyze_Subtype_Declaration): Clean up inheritance of
2065 predicates for subtype declarations and for subtype indications in

2176 * sem_ch5.adb (Preanalyze_Range): The pre-analysis of the domain of
2177 iteration of an Ada2012 loop is performed to determine the type of the
2178 domain, but full analysis is performed once the loop is rewritten as a
2179 while-loop during expansion. The pre-analysis suppresses expansion; it
2180 must also suppress the generation of freeze nodes, which may otherwise
2181 appear in the wrong scope before rewritting.

3034 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3036 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Check the
3037 categorization of a subprogram body which does not complete a previous
3040 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3042 * sem_ch10.adb (Check_Private_Child_Unit): Ensure that the enclosing
3043 scope of package Ada is Standard.
3045 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3047 * sem_ch13.adb (Replace_Type_Ref): Handle properly reference to a
3048 subcomponent of the current entity when building the body for a dynamic
3049 predicate function for a record with composite subcomponents.
3051 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3053 * exp_aggr.adb (Convert_Aggr_In_Object_Decl): Update the call to
3054 Establish_Transient_Scope.
3055 (Convert_To_Assignments): Update the call to Establish_Transient_Scope.
3056 (Expand_Array_Aggregate): Update the call to Establish_Transient_Scope.
3057 * exp_ch6.adb (Expand_Call_Helper): Update the call to
3058 Establish_Transient_Scope.
3059 (Make_Build_In_Place_Call_In_Object_Declaration): Update the call to
3060 Establish_Transient_Scope.
3061 * exp_ch7.adb (Establish_Transient_Scope): Restructured. Delegate the
3062 management of the secondary stack to an enclosing scope if there is no
3063 suitable construct to wrap, and the transient scope was intended to
3064 manage the secondary stack.
3065 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
3066 is a valid boundary for a transient expression which comes from the
3067 statements of the alternative, otherwise alternatives cannot be
3068 wrapped. Assignments of controlled objects which have controlled
3069 actions suppressed now stop the traversal as there is no point in
3070 looking for an enclosing construct. Add several N_xxx_Body choices to
3071 the termination conditions for completeness.
3072 * exp_ch7.ads (Establish_Transient_Scope): Update the parameter profile
3073 and the associated comment on usage.
3074 * exp_smem.adb (Add_Shared_Var_Lock_Procs): Update the call to
3075 Establish_Transient_Scope.
3076 (Add_Write_After): Update the call to Establish_Transient_Scope.
3077 * sem_res.adb (Check_Initialization_Call): Removed.
3078 (Resolve_Actuals): Account for additional cases where finalization
3079 actions are required by utilizing predicate Needs_Finalization rather
3081 (Resolve_Call): Type initialization procedures can now utilize
3082 transient scopes to manage the secondary stack, thus preventing leaks
3083 during initialization. Remove the previous kludgy algorithm which
3084 attempts to manage the secondary stack at the object creation site.
3086 2018-01-11 Jerome Lambourg <lambourg@adacore.com>
3088 * libgnat/g-soliop__qnx.ads: New.
3089 * adaint.c, adaint.h, cstreams.c, s-oscons-tmplt.c, sysdep.c: Update
3092 2018-01-11 Bob Duff <duff@adacore.com>

3119 * doc/Makefile: Add Sphinx option -W to treat warnings as errors.
3121 2018-01-11 Ben Brosgol <brosgol@adacore.com>
3123 * doc/gnat_rm/implementation_defined_aspects.rst: Minor type/wording
3125 * gnat_rm.texi: Regenerate.
3127 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3129 * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
3130 formsl type corresponding to the actual fixed point type is private,
3131 because in this case there can be no suspicious arithmetic operations
3132 in the generic unless they reference a formal subprogram. Clarify
3135 2018-01-11 Javier Miranda <miranda@adacore.com>
3137 * exp_util.adb (Remove_Side_Effects): No action done for functions
3138 returning class-wide types since it requires generating code using
3139 'reference and the CCG target has no secondary stack.
3140 * gnat1drv.adb: Disable building static dispatch tables when generating
3143 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
3145 * libgnat/a-direio.ads, libgnat/a-sequio.ads, libgnat/a-ststio.ads,
3146 libgnat/a-textio.ads, libgnat/a-witeio.ads, libgnat/a-ztexio.ads
3147 (File_Type): Add Default_Initial_Condition aspect.
3149 2018-01-11 Pascal Obry <obry@adacore.com>
3151 * libgnat/s-os_lib.adb (Normalize_Pathname): New implementation.
3153 2018-01-11 Bob Duff <duff@adacore.com>
3155 * doc/gnat_ugn/gnat_utility_programs.rst: Rewrite gnatpp documentation
3156 to match what the Libadalang-based version does.
3157 * doc/gnat_ugn/about_this_guide.rst: Update reference.
3159 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3161 * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
3162 if it contains at least one component declaration employing a function
3163 call returning on the secondary stack.
3165 2018-01-11 Yannick Moy <moy@adacore.com>
3167 * doc/gnat_rm/standard_and_implementation_defined_restrictions.rst:
3168 Update description of restriction SPARK_05 with SPARK 2014.

3177 * exp_aggr.adb, exp_ch9.adb, exp_util.adb, sem_aggr.adb, sem_ch3.adb,
3178 sem_res.adb, sem_util.adb: Minor reformatting.
3180 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3182 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
3183 has a delayed aspect which must be processed at the point the type is
3184 frozen. This mimics what is done when the predicate is provided by a
3187 2018-01-11 Doug Rupp <rupp@adacore.com>
3189 * init.c (vxworks): Add macro checks for __aarch64__.
3191 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3193 * exp_util.adb (Add_Failure_Expression): New routine.
3194 (Make_Predicate_Check): Reimplement the handling of Predicate_Failure.
3195 * sem_util.adb (Is_Current_Instance): Code cleanup.
3197 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
3199 * libgnat/s-parame*.adb, libgnat/s-parame*.ads: Remove unneeded
3200 Default_Sec_Stack_Size.
3201 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
3202 limit check so that the integer index does not overflow. Check the
3203 dynamic stack allocation does not cause the secondary stack pointer to
3205 (SS_Info): Align colons.
3206 (SS_Init): Cover the case when bootstraping with an old compiler that
3207 does not set Default_SS_Size.
3209 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3211 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
3212 legality of an inherited operation that may require overriding, ignore
3213 primitive_wrappers that correspond to explicit operations that override
3214 an interface primitive.
3215 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
3216 operation to which the class-wide expression applies is a protected op.
3217 with a primitive_wrapper, verify that the updated inherited expression
3218 does not contain an internal call to a protected function. This
3219 completes the implementation of AI12-0166.
3221 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3223 * ali.adb: Document the remaining letters available for ALI lines.
3224 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
3225 * ali.ads: Update type With_Record. Field
3226 Implicit_With_From_Instantiation is no longer in use. Add field
3228 * csinfo.adb (CSinfo): Remove the setup for attribute
3229 Implicit_With_From_Instantiation.
3230 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
3231 either implicitly or explicitly withed.
3232 (Is_Implicit_With_Clause): New routine.
3233 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
3234 confusion with the with clause attribute by the same name.
3235 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
3236 * rtsfind.adb (Maybe_Add_With): Code cleanup.
3237 * sem_ch8.adb (Present_System_Aux): Code cleanup.
3238 * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
3240 (Implicit_With_On_Parent): Mark the with clause as generated for a
3242 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
3243 instantiation are no longer marked as Implicit_With_From_Instantiation
3244 because they are already marked as implicit.
3245 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
3246 which marks implicit with clauses as related to an instantiation.
3247 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
3248 (Parent_With): New routine.
3249 (Set_Implicit_With_From_Instantiation): Removed.
3250 (Set_Parent_With): New routine.
3251 * sinfo.ads: Update the documentation of attribute Implicit_With.
3252 Remove attribute Implicit_With_From_Instantiation along with
3253 occurrences in nodes. Add attribute Parent_With along with occurrences
3255 (Implicit_With_From_Instantiation): Removed along with pragma Inline.
3256 (Parent_With): New routine along with pragma Inline.
3257 (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.
3258 (Set_Parent_With): New routine along with pragma Inline.
3260 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3262 * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
3263 entity when the enclosing construct is a body.
3265 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
3267 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
3268 Secondary_Stack_Size handling as a pragma is now generated for the
3269 corresponding aspect instead of an attribute. Pragma expression is
3270 relocated instead of evaluated. Discriminant of the corresponding
3271 record type is referenced rather than the type discriminant.
3272 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
3273 Secondary_Stack_Size rep item checks to only look for the pragma rep.
3274 * sem_ch13.adb (Analyze_One_Aspect): Transform
3275 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
3276 because the attribute does not have visibility on a task type's
3277 discriminants when the type's definition is expanded.
3278 (Analyze_Attribute_Definition_Clause): Remove handling of
3279 Attribute_Secondary_Stack_Size.
3280 * snames.adb-tmpl, snames.ads-tmpl: Remove
3281 Attribute_Secondary_Stack_Size, no longer used.
3283 2018-01-11 Justin Squirek <squirek@adacore.com>

3287 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3289 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
3290 individual action because the action may denote a complex expression,
3291 such as a case statement, which in turn may contain additional
3294 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3296 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
3297 analysis on a copy of the expression with a copy of the index variable,
3298 because full expansion will rewrite construct into a loop with the
3299 original loop variable.
3300 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
3301 expression is an iterated component association. Full analysis takes
3302 place when construct is rewritten as a loop.
3303 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
3304 is not safe for in-place assignment.
3305 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
3306 entity with no homonym and no other entity in the scope.
3308 2018-01-11 Justin Squirek <squirek@adacore.com>
3310 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
3311 message to be printed on the pragma argument identifier.
3313 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3315 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
3316 entity of the generated invariant procedure in order to construct a
3317 proper entity chain.
3319 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
3321 * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
3324 2018-01-11 Arnaud Charlet <charlet@adacore.com>
3326 * einfo.ads, einfo.adb (Activation_Record_Component,
3327 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
3328 Allow E_Discriminant.
3330 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
3332 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
3333 for atomic access once the component size is taken into account and
3334 also do it if the component type is Atomic or Volatile_Full_Access.
3336 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
3338 * gnatvsn.ads: Bump copyright year.
