875 comment about the memset case.
877 2018-05-30 Bob Duff <duff@adacore.com>
879 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
880 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
881 We need to analyze it as part of analyzing the block, so that if the
882 call to Element that initializes Elmt_Decl returns on the secondary
883 stack, the block will ss_mark/ss_release. This block is inside the
884 loop; we don't want to leak memory until the loop exits. The purpose
885 of analyzing Elmt_Decl first was to catch the error of modifying it,
886 which is illegal because it's a loop parameter. The above causes us to
887 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
888 it on the Element entity, so we end up with an E_Variable node with the
890 * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.
891 * sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop
892 parameter not allowed" error if Is_Loop_Parameter.
893 * sem_util.adb (Is_Variable): Return False if Is_Loop_Parameter, to
894 trigger the call to Diagnose_Non_Variable_Lhs.

898 * checks.adb (Apply_Scalar_Range_Check):
899 * sem_eval.adb (Check_Non_Static_Context, Out_Of_Range): Ignore out of

901 target compiler may provide a wider range.

908 2018-05-30 Ed Schonberg <schonberg@adacore.com>
910 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
911 a package body that is a compilation unit may contain blocks that
912 declare local subprograms. In Subprogram_Unnesting Mode such
913 subprograms must be handled as nested inside the (implicit) elaboration
914 procedure that executes that statement part. To handle properly uplevel
915 references we construct that subprogram explicitly, to contain blocks
916 and inner subprograms, The statement part of the compilation unit
917 becomes a call to this subprogram. This is only done if blocks are
918 present in the statement list of the body.
920 2018-05-30 Bob Duff <duff@adacore.com>

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

1225 references, examine index expressions or associated expressions as well
1226 to record uplevel references.

1229 of actual have uplevel references.
1231 2018-05-28 Ed Schonberg <schonberg@adacore.com>

1242 Size_Depends_On_Discriminant in the array type case.
1244 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1246 * exp_unst.adb (Check_Static_Type): For a record subtype, check
1247 discriminant constraints as well.
1248 (Visit_Node): For a selected component, check type of prefix, as is
1249 done for indexed components and slices.
1251 2018-05-28 Javier Miranda <miranda@adacore.com>
1253 * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
1254 value when converting a float value to a fixed-point value. This is
1255 required for CCG because it handles fixed-point types by means of
1256 unsigned integer type variables. The range check is now performed using
1257 the integer value stored in this temporary.
1259 2018-05-28 Yannick Moy <moy@adacore.com>

1282 component type, do not expand array equality using the unconstrained
1283 base type, except for the case where the bounds of the type depend on a
1286 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1288 * einfo.ads, einfo.adb (Needs_Activation_Record): New flag on
1289 access-to-subprogram types, to indicate that an indirect call through
1290 such a type requires an activation record when compiling for LLVM.
1291 * sem_ch3.adb (Access_Subprogram_Declaration): Set new flag as needed.
1293 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1295 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
1296 when bounds of fixed type are static, to remove some spuerfluous
1297 implicit conversions and provide an accurate result when converting
1298 back and forth between the fixed point type and a floating point type.
1300 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1302 * exp_unst.adb (Unnest_Subprogram): Prevent creation of empty
1305 2018-05-28 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
1307 * exp_unst.adb (Check_Static_Type): Add argument to indicate node to be
1308 replaced, if any; all callers changed.
1309 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
1310 constant with private view so we take the address of that entity.
1311 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
1312 any; all callers changed. Handle N_Indexed_Component like
1313 N_Attribute_Reference. Add N_Type_Conversion case.
1314 (Visit_Node): Indexed references can be uplevel if the type isn't
1316 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
1317 been relocated, set first_named pointer in original node as well.
1319 2018-05-28 Ed Schonberg <schonberg@adacore.com>
1321 * exp_aggr.adb (Flatten): Copy tree of expression in a component
1322 association with a range or a set of discrete choices, rather than
1323 relocating the node. This avoids inconsistencies in the tree when
1324 handling nested subprograms with uplevel references for LLVM.

1379 * sem_prag.adb (Process_Atomic_Independent_Shared_Volatile): Include
1380 the declarations of single concurrent types because they fall in the
1381 category of full type and object declarations.

1390 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
1391 includes a call to function to which it applies. This may mean an
1392 omission of an attribute reference 'Result, in particular if the
1393 function is pqrameterless.
1395 2018-05-28 Justin Squirek <squirek@adacore.com>

1402 * sem_res.adb (Resolve_Range): Re-resolve the low bound of a range in

1409 * repinfo.adb (List_Array_Info): Start with an explicit blank line and
1410 end with the linker section, if any.
1411 (List_Entities): Do not output the linker section for record types,
1412 array types and variables.
1413 (Print_Expr): Factor out common processing for unary operators and
1414 special values. Adjust and reorder the various cases.
1415 (List_Object_Info): End with the linker section, if any.
1416 (List_Record_Info): Likewise.
1417 (List_Type_Info): Do not start with a blank line.
1419 2018-05-25 Nicolas Roche <roche@adacore.com>
1421 * libgnat/s-valrea.adb (Scan_Real): Abort computation once it is sure
1422 that the result will be either -infinite or +infinite.
1424 2018-05-25 Patrick Bernardi <bernardi@adacore.com>
1426 * libgnat/s-parame.ads, libgnat/s-parame__vxworks.ads,

1428 Expand range of type to match the address space of the target.
1429 (Task_Storage_Size): Remove unused type.
1431 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1433 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
1434 of a fixed point type and the parent is a multiplying operation,
1435 resolve the operand with its own type because the context will impose a
1436 resulting type on the result of the multiplication by means of
1437 approriate conversion.
1439 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1441 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
1442 the in-place initialization aggregate created for pragmas
1443 Initialize_Scalars or Normalize_Scalars is performed with checks
1446 2018-05-25 Arnaud Charlet <charlet@adacore.com>
1448 * exp_aggr.adb (Convert_To_Positional): Bump default for
1449 Max_Others_Replicate to 32. Update comments.
1450 * osint.ads (Unknown_Attributes): No longer pretend this is a constant.
1451 (No_File_Info_Cache): Initialize separately.

1456 * sem_res.adb (Resolve_Membership_Op): Allow the use of the membership
1457 test when the left operand is a class-wide interface and the right
1458 operand is not a class-wide type.

1462 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1464 * exp_aggr.adb (Flatten): A quantified expression cannot be duplicated

1468 (Check_Static_Component): Ditto.
1470 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
1472 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
1473 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
1474 into three distring cases rather than in one loop which attempts to
1475 handle all three cases. This rewrite eliminates an issue where the last
1476 frame of the stack cannot be freed, thus causing the memory range of a
1477 new frame to approach the overflow point of the memory index type.
1478 Since the overflow is logically treated as a
1479 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
1480 (SS_Allocate_Static): New routine. The routine factorizes the static
1481 secondary stack-related code from the former SS_Allocate.
1483 2018-05-25 Sergey Rybin <rybin@adacore.com>
1485 * doc/gnat_ugn/gnat_and_program_execution.rst: Add description of '-U'
1486 option for gnatelim.
1488 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1490 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
1491 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
1492 is created when the proper body of the stub is analyzed.
1493 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
1494 is the proper body of a subunit, the cloned body must be inserted in
1495 the declarative list that contains the stub.
1497 2018-05-25 Justin Squirek <squirek@adacore.com>
1499 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
1500 generate code for 6.5(8-10) so that we don't get an assertion error
1501 when dealing with an incomplete return type.
1503 2018-05-25 Arnaud Charlet <charlet@adacore.com>
1505 * pprint.adb (Expression_Name): Strip too long expressions to avoid
1506 carrying very large strings.

1532 2018-05-25 Ed Schonberg <schonberg@adacore.com>
1534 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
1535 Validate_Derived_Type_Instance, to verify that all interfaces
1536 implemented by the formal type are also implemented by the actual. The
1537 verification is complicated when an interface of the formal is declared
1538 in a generic unit and the actual is declared in an instance of it.
1539 There is currently no mechanism to relate an interface declared within
1540 a generic to the corresponding interface in an instance, so we must
1541 traverse the list of interfaces of the actual, looking for a name
1542 match, and verifying that that interface is declared in an instance.
1544 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
1546 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra
1547 assertions; replace function versions of Next_Formal/Next_Actual with
1548 their procedural versions (which are more concise).

2778 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
2779 delegate the secondary stack management when there is no suitable
2780 transient context, and the transient scope was intended to manage the

2785 the comment on usage.
2786 (Find_Transient_Context): Change the initinte loop into a while loop.

3018 during initialization. Remove the previous kludgy algorithm which
3019 attempts to manage the secondary stack at the object creation site.

3060 * gnat_rm.texi: Regenerate.
3062 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3064 * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
3065 formsl type corresponding to the actual fixed point type is private,
3066 because in this case there can be no suspicious arithmetic operations
3067 in the generic unless they reference a formal subprogram. Clarify
3070 2018-01-11 Javier Miranda <miranda@adacore.com>
3072 * exp_util.adb (Remove_Side_Effects): No action done for functions
3073 returning class-wide types since it requires generating code using
3074 'reference and the CCG target has no secondary stack.
3075 * gnat1drv.adb: Disable building static dispatch tables when generating
3078 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
3080 * libgnat/a-direio.ads, libgnat/a-sequio.ads, libgnat/a-ststio.ads,

3082 (File_Type): Add Default_Initial_Condition aspect.
3084 2018-01-11 Pascal Obry <obry@adacore.com>
3086 * libgnat/s-os_lib.adb (Normalize_Pathname): New implementation.
3088 2018-01-11 Bob Duff <duff@adacore.com>
3090 * doc/gnat_ugn/gnat_utility_programs.rst: Rewrite gnatpp documentation
3091 to match what the Libadalang-based version does.

3094 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3096 * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
3097 if it contains at least one component declaration employing a function
3098 call returning on the secondary stack.
3100 2018-01-11 Yannick Moy <moy@adacore.com>

3113 sem_res.adb, sem_util.adb: Minor reformatting.
3115 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3117 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
3118 has a delayed aspect which must be processed at the point the type is
3119 frozen. This mimics what is done when the predicate is provided by a
3122 2018-01-11 Doug Rupp <rupp@adacore.com>
3124 * init.c (vxworks): Add macro checks for __aarch64__.

3135 Default_Sec_Stack_Size.
3136 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
3137 limit check so that the integer index does not overflow. Check the
3138 dynamic stack allocation does not cause the secondary stack pointer to
3140 (SS_Info): Align colons.
3141 (SS_Init): Cover the case when bootstraping with an old compiler that
3142 does not set Default_SS_Size.
3144 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3146 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
3147 legality of an inherited operation that may require overriding, ignore
3148 primitive_wrappers that correspond to explicit operations that override
3149 an interface primitive.
3150 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
3151 operation to which the class-wide expression applies is a protected op.
3152 with a primitive_wrapper, verify that the updated inherited expression
3153 does not contain an internal call to a protected function. This
3154 completes the implementation of AI12-0166.
3156 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3158 * ali.adb: Document the remaining letters available for ALI lines.
3159 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
3160 * ali.ads: Update type With_Record. Field
3161 Implicit_With_From_Instantiation is no longer in use. Add field
3163 * csinfo.adb (CSinfo): Remove the setup for attribute
3164 Implicit_With_From_Instantiation.
3165 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
3166 either implicitly or explicitly withed.
3167 (Is_Implicit_With_Clause): New routine.
3168 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
3169 confusion with the with clause attribute by the same name.
3170 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
3171 * rtsfind.adb (Maybe_Add_With): Code cleanup.
3172 * sem_ch8.adb (Present_System_Aux): Code cleanup.
3173 * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
3175 (Implicit_With_On_Parent): Mark the with clause as generated for a
3177 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
3178 instantiation are no longer marked as Implicit_With_From_Instantiation
3179 because they are already marked as implicit.
3180 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
3181 which marks implicit with clauses as related to an instantiation.
3182 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
3183 (Parent_With): New routine.
3184 (Set_Implicit_With_From_Instantiation): Removed.
3185 (Set_Parent_With): New routine.
3186 * sinfo.ads: Update the documentation of attribute Implicit_With.
3187 Remove attribute Implicit_With_From_Instantiation along with
3188 occurrences in nodes. Add attribute Parent_With along with occurrences
3190 (Implicit_With_From_Instantiation): Removed along with pragma Inline.
3191 (Parent_With): New routine along with pragma Inline.
3192 (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.

3195 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3197 * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
3198 entity when the enclosing construct is a body.
3200 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
3202 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
3203 Secondary_Stack_Size handling as a pragma is now generated for the
3204 corresponding aspect instead of an attribute. Pragma expression is
3205 relocated instead of evaluated. Discriminant of the corresponding
3206 record type is referenced rather than the type discriminant.
3207 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
3208 Secondary_Stack_Size rep item checks to only look for the pragma rep.
3209 * sem_ch13.adb (Analyze_One_Aspect): Transform
3210 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
3211 because the attribute does not have visibility on a task type's
3212 discriminants when the type's definition is expanded.
3213 (Analyze_Attribute_Definition_Clause): Remove handling of
3214 Attribute_Secondary_Stack_Size.
3215 * snames.adb-tmpl, snames.ads-tmpl: Remove
3216 Attribute_Secondary_Stack_Size, no longer used.

3222 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3224 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
3225 individual action because the action may denote a complex expression,
3226 such as a case statement, which in turn may contain additional
3229 2018-01-11 Ed Schonberg <schonberg@adacore.com>
3231 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
3232 analysis on a copy of the expression with a copy of the index variable,
3233 because full expansion will rewrite construct into a loop with the
3234 original loop variable.
3235 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
3236 expression is an iterated component association. Full analysis takes
3237 place when construct is rewritten as a loop.
3238 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
3239 is not safe for in-place assignment.
3240 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
3241 entity with no homonym and no other entity in the scope.
3243 2018-01-11 Justin Squirek <squirek@adacore.com>
3245 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
3246 message to be printed on the pragma argument identifier.
3248 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
3250 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
3251 entity of the generated invariant procedure in order to construct a
3252 proper entity chain.
3254 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
3256 * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
3259 2018-01-11 Arnaud Charlet <charlet@adacore.com>
3261 * einfo.ads, einfo.adb (Activation_Record_Component,
3262 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
3263 Allow E_Discriminant.
3265 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
3267 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
3268 for atomic access once the component size is taken into account and
3269 also do it if the component type is Atomic or Volatile_Full_Access.
3271 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
3273 * gnatvsn.ads: Bump copyright year.
