1385 (Build_DIC_Procedure_Body): Call Add_Parent_DICs to generate

1387 the required "additive" semantics for DICs. When building a DIC

1389 call Add_Own_DIC when the type has its own DIC. In the case of
1390 "full" DIC procedures, a call is generated to any partial DIC

1392 along with checks for any DICs inherited by the full view.

3581 * aspects.ads: Introduce the subtype Nonoverridable_Aspect_Id,
3582 whose Static_Predicate reflects the list of nonoverridable
3583 aspects given in Ada RM 13.1.1(18.7).
3584 * sem_util.ads, sem_util.adb: Add two new visible subprograms,
3585 Check_Inherited_Nonoverridable_Aspects and Is_Confirming. The
3586 former is used to check the consistency of inherited
3587 nonoverridable aspects from multiple sources. The latter
3588 indicates whether two aspect specifications for a nonoverridable
3589 aspect are confirming. Because of compatibility concerns in
3590 compiling QGen, Is_Confirming always returns True if
3591 Relaxed_RM_Semantics (i.e., -gnatd.M) is specified.
3592 * sem_ch3.adb (Derived_Type_Declaration): Call new
3593 Check_Inherited_Nonoverridable_Aspects procedure if interface

3616 2020-10-22 Steve Baird <baird@adacore.com>
3618 * sem_util.adb (Is_Container_Aggregate): A new local predicates
3619 which indicates whether a given expression is a container
3620 aggregate. The implementation of this function is incomplete; in
3621 the unusual case of a record aggregate (i.e., not a container
3622 aggregate) of a type whose Aggregate aspect is specified, the
3623 function will incorrectly return True.
3624 (Immediate_Context_Implies_Is_Potentially_Unevaluated): Improve
3625 handling of aggregate components.
3626 (Is_Repeatedly_Evaluated): Test for container aggregate
3627 components along with existing test for array aggregate
3628 components.
3630 2020-10-22 Eric Botcazou <ebotcazou@adacore.com>
3632 * exp_fixd.adb (Fpt_Value): Fold if-then-else with identical arms.
3634 2020-10-22 Ed Schonberg <schonberg@adacore.com>
3636 * par-ch4.adb (P_Iterated_Component_Association): If the
3637 construct includes an iterator filter it corresponds to an
3638 Iterated_Element_Association, so build the proper node for it.
3639 * exp_aggr.adb (Expand_Container_Aggregate, Aggregate_Size): If
3640 the component is an Iterated_Element_Association, treat it as
3641 having a non-static size.
3643 2020-10-22 Ghjuvan Lacambre <lacambre@adacore.com>
3645 * scng.adb (Scan): Check if any letter of the token is
3646 uppercase.
3648 2020-10-22 Justin Squirek <squirek@adacore.com>
3650 * sem_util.adb (Accessibility_Level_Helper): Conversions to
3651 named access types get the level associated with the named
3652 access type.

3661 * sem_res.adb (Resolve_Actuals.Check_Aliased_Parameter): Remove
3662 "not Is_Generic_Type" test and call
3663 Object_Type_Has_Constrained_Partial_View instead of
3664 Has_Constrained_Partial_View. Improve related error message to
3665 say "does not statically match" instead of just "does not
3666 match".
3668 2020-10-22 Steve Baird <baird@adacore.com>
3670 * sem_util.ads, sem_util.adb: Declare and implement a new
3671 predicate, Derivation_Too_Early_To_Inherit. This function
3672 indicates whether a given derived type fails to inherit a given
3673 streaming-related attribute from its parent type because the
3674 declaration of the derived type precedes the corresponding
3675 attribute_definition_clause of the parent.
3676 * exp_tss.adb (Find_Inherited_TSS): Call
3677 Derivation_Too_Early_To_Inherit instead of unconditionally
3678 assuming that a parent type's streaming attribute is available
3679 for inheritance by an immediate descendant type.
3680 * sem_attr.adb (Stream_Attribute_Available): Call
3681 Derivation_Too_Early_To_Inherit instead of unconditionally
3682 assuming that a parent type's streaming attribute is available
3683 for inheritance by an immediate descendant type.
3684 * exp_attr.adb (Default_Streaming_Unavailable): A new predicate;
3685 given a type, indicates whether predefined (as opposed to
3686 user-defined) streaming operations for the type should be
3687 implemented by raising Program_Error.
3688 (Expand_N_Attribute_Reference): For each of the 4
3689 streaming-related attributes (i.e., Read, Write, Input, Output),
3690 after determining that no user-defined implementation is
3691 available (including a Stream_Convert pragma), call
3692 Default_Streaming_Unavailable; if that call returns True, then
3693 implement the streaming operation as "raise Program_Error;".
3695 2020-10-22 Eric Botcazou <ebotcazou@adacore.com>
3697 * checks.adb (Apply_Float_Conversion_Check): Saturate the bounds
3698 of the check to those of the base type of the expression.

3712 of the new extra accessibility paramter actual needed for init
3713 procs.
3714 (Init_Proc_Level_Formal): Created to fetch a the extra
3715 accessibility parameter associated with init procs if one
3716 exists.

3720 used to expand conditional expressions used as actuals for
3721 anonymous access formals.
3722 (Expand_Call_Helper): Remove extranious accessibility
3723 calculation logic.
3724 * exp_util.adb: Remove inclusion of Exp_Ch2.adb.

3734 * sem_ch9.adb (Analyze_Requeue): Replace instances for
3735 Object_Access_Level with Static_Accessibility_Level.
3736 * sem_res.adb (Check_Aliased_Parameter,
3737 Check_Allocator_Discrim_Accessibility, Valid_Conversion):
3738 Replace instances for Object_Access_Level with
3739 Static_Accessibility_Level.
3740 * sem_util.adb, sem_util.ads (Accessibility_Level_Helper):
3741 Created to centralize calculation of accessibility levels.
3742 (Build_Component_Subtype): Replace instances for
3743 Object_Access_Level with Static_Accessibility_Level.
3744 (Defining_Entity): Add extra parameter to dictate whether an
3745 error is raised or empty is return in the case of an irrelevant
3746 N.
3747 (Dynamic_Accessibility_Level): Rewritten to use
3748 Accessibility_Level_Helper.
3749 (Is_View_Conversion): Check membership against Etype to capture
3750 nodes like explicit dereferences which have types but are not
3751 expanded names or identifers.
3752 (Object_Access_LeveL): Removed.
3753 (Param_Entity): Moved from sem_util.
3754 (Static_Accessibility_Level): Created as a replacement to
3755 Object_Access_Level, it also uses Accessibility_Level_Helper for
3756 its implementation.
3757 * snames.ads-tmpl: Added new name for extra accessibility
3758 parameter in init procs.
3760 2020-10-22 Piotr Trojanek <trojanek@adacore.com>

4515 2020-10-20 Piotr Trojanek <trojanek@adacore.com>
4517 * einfo.adb, exp_attr.adb, sem_ch13.adb, sem_util.adb: Use
4518 Is_Formal where possible.
4520 2020-10-20 Steve Baird <baird@adacore.com>
4522 * sem_util.ads: Declare a new package, Old_Attr_Util, which in
4523 turn declares two more packages, Conditional_Evaluation and
4524 Indirect_Temps. Conditional_Evaluation provides a predicate for
4525 deciding whether a given 'Old attribute reference is eligible
4526 for conditional evaluation and, in the case where it is
4527 eligible, a function that constructs the Boolean-valued
4528 condition that is to be evaluated at run time in deciding
4529 whether to evaluate the attribute prefix. Indirect_Temps
4530 provides support for declaring a temporary which is only
4531 initialized conditionally; more specifically, an access type and
4532 a variable of that type are declared (unconditionally) and then
4533 the variable is (conditionally) initialized with an allocator.
4534 The existence of the access type and the pointer variable is
4535 hidden from clients, except that a predicate,
4536 Is_Access_Type_For_Indirect_Temp, is provided for identifying
4537 such access types. This is needed because we want such an access
4538 type to be treated like a "normal" access type (specifically
4539 with respect to finalization of allocated objects). Other parts
4540 of the compiler treat access types differently if
4541 Comes_From_Source is False, or if the secondary stack storage
4542 pool is used; this predicate is used to disable this special
4543 treatment.
4544 * sem_attr.adb (Uneval_Old_Msg): Improve message text to reflect
4545 Ada202x changes.
4546 (Analyze_Attribute): A previously-illegal 'Old attribute
4547 reference is accepted in Ada2020 if it is eligible for
4548 conditional evaluation.
4549 * sem_res.adb (Valid_Conversion): Do not treat a rewritten 'Old
4550 attribute like other rewrite substitutions. This makes a
4551 difference, for example, in the case where we are generating the
4552 expansion of a membership test of the form "Saooaaat'Old in
4553 Named_Access_Type"; in this case Valid_Conversion needs to
4554 return True (otherwise the expansion will be False - see the
4555 call site in exp_ch4.adb).
4556 * exp_attr.adb (Expand_N_Attribute_Reference): When expanding a
4557 'Old attribute reference, test for the case where the reference
4558 is eligible for conditional evaluation. In that case, use the
4559 new "indirect temporary" mechanism provided by Sem_Util.
4560 * exp_prag.adb
4561 (Expand_Attributes_In_Consequence.Expand_Attributes): If
4562 Sem_Util.Indirect_Temp_Needed indicates that there could be
4563 correctness problems associated with the old expansion scheme
4564 for dealing with 'Old attributes in contract cases consequences,
4565 then we use the new "indirect temporary" mechanism provided by
4566 Sem_Util instead. We do not want to do this unconditionally.
4567 * sem_util.adb: Provide a body for the new Old_Attr_Util
4568 package. Further work is needed in several areas for
4569 correctness:
4570 - The function Is_Repeatedly_Evaluated does not deal with
4571 container aggregates yet.
4572 - The function Is_Known_On_Entry does not deal with interactions
4573 with the Global aspect.
4574 Each area where more work is needed is indicated with a "???"
4575 comment in the code; a more detailed description can be found
4576 there. Some optimization opportunties are similarly indicated
4577 with a "???" comment.
4578 * exp_ch3.adb (Freeze_Type): In deciding whether to generate
4579 expansion for the list controller of an access type, take the
4580 predicate Is_Access_Type_For_Indirect_Temp into account. If the
4581 predicate yields True, then generate the expansion.
4582 * exp_util.adb (Build_Allocate_Deallocate_Proc): We don't
4583 normally finalize allocated objects that are allocated on the
4584 secondary stack. Add an exception to this rule if the predicate
4585 Is_Access_Type_For_Indirect_Temp yields True. As a result of
4586 this exception, we have to deal with the fact that gigi expects
4587 a different parameter profile if we are using the secondary
4588 stack pool; the Pool and Alignment parameters must be omitted in
4589 this case.
4591 2020-10-20 Javier Miranda <miranda@adacore.com>
4593 * sem_ch12.adb (Install_Parents_Of_Generic_Context,
4594 Remove_Parents_Of_Generic_Context): New subprograms.
4595 (Instantiate_Package_Body): Adding assertions to ensure that
4596 installed parents are properly removed.
4598 2020-10-20 Claire Dross <dross@adacore.com>
4600 * sem_attr.adb (Analyze_Attribute): Emit a warning on 'Update
4601 when Warn_On_Obsolescent_Feature is set to True.
4603 2020-10-20 Richard Kenner <kenner@adacore.com>
4605 * gnat_cuda.adb (Build_Register_Function_Call): Make procedure
4606 call instead of function, rename to
4607 Build_Register_Procedure_Call.
4608 (Build_CUDA_Init_Proc): Make procedure call instead of function.
4610 2020-10-20 Justin Squirek <squirek@adacore.com>
4612 * exp_ch6.adb (Expand_Branch): Properly anticipate expansion of
4613 conditional expressions producing object declarations in
4614 addition to assignment statements, and rename formal.
4616 2020-10-20 Yannick Moy <moy@adacore.com>
4618 * errout.adb (Write_Source_Code_Line): Adopt display closer to
4619 GCC format.
4620 (Output_Messages): Deal specially with info messages.
4621 * erroutc.adb (Prescan_Message): Fix bug leading to check
4622 messages being considered as error messages in pretty output
4623 mode.
4625 2020-10-20 Justin Squirek <squirek@adacore.com>
4627 * exp_ch6.adb (Expand_Call_Helper): Properly handle the case
4628 where the condition of a conditional expression has been
4629 optimized out when calculating the value of an extra
4630 accessibility parameter.
4632 2020-10-20 Bob Duff <duff@adacore.com>
4634 * doc/gnat_ugn/gnat_utility_programs.rst: Change "_" to "-".
4636 2020-10-20 Arnaud Charlet <charlet@adacore.com>
4638 * sem_aggr.adb (Resolve_Aggregate): Warn on not fully
4639 initialized box aggregate.
4640 * sem_aggr.ads: Fix typo.
4641 * sem_res.adb (Resolve_Actuals): Fix typo in error message
4642 format marking it incorrectly as a continuation message.
4643 * sem_elab.adb (Check_Internal_Call_Continue): Similarly, add
4644 missing primary message in case of a call to an actual generic
4645 subprogram.
4646 * sem_warn.adb (Check_References): Do not warn on read but never
4647 assigned variables if the type is partially initialized.
4648 * libgnat/a-except.ads, libgnat/a-ststun.ads,
4649 libgnat/g-sechas.ads, libgnat/a-cbdlli.ads,
4650 libgnat/a-cfdlli.ads, libgnat/a-cobove.ads,
4651 libgnat/a-cohata.ads, libgnat/a-crbltr.ads,
4652 libgnat/a-cbmutr.ads, libgnat/a-crdlli.ads,
4653 libgnat/a-cbsyqu.ads: Address new warning.
4654 * doc/gnat_ugn/building_executable_programs_with_gnat.rst:
4655 Update doc on -gnatwv.
4656 * gnat_ugn.texi: Regenerate.
4658 2020-10-20 Gary Dismukes <dismukes@adacore.com>
4660 * sem_ch6.adb (Analyze_Expression_Function): Mark static
4661 expression functions as inlined.
4663 2020-10-20 Arnaud Charlet <charlet@adacore.com>
4665 * contracts.adb (Is_Prologue_Renaming): This function was
4666 missing support for E_Constant which can also be generated in
4667 protected objects.
4669 2020-10-20 Arnaud Charlet <charlet@adacore.com>
4671 * bindgen.adb (Gen_Bind_Env_String): Generate Ada 2012 compatible
4672 strings. Code cleanup.
4674 2020-10-20 Yannick Moy <moy@adacore.com>
4676 * sem_util.adb, sem_util.ads: Comment fix.
4678 2020-10-20 Arnaud Charlet <charlet@adacore.com>
4680 * sem_ch8.adb (Check_Constrained_Object): Suppress discriminant
4681 checks when the type has default discriminants and comes from
4682 expansion of a "for of" loop.
4684 2020-10-20 Bob Duff <duff@adacore.com>
4686 * atree.ads: Make Default_Node a constant. Remove the
4687 modification of Comes_From_Source, and use a separate flag for
4688 that. Change Sloc to 0; it always overwritten, and never left
4689 as the No_Location value.
4690 (Print_Statistics): Move to spec so we can call it from
4691 gnat1drv.
4692 (Num_Nodes): Rename to clarify that this is approximate.
4693 Correct comment: nodes and entities are never deleted, the count
4694 is never decremented, and this is not used by Xref.
4695 (Initialize): Correct comment: Error_List is not created here.
4696 Other minor naming and comment changes.
4697 * atree.adb (Extend_Node, New_Copy, New_Entity, New_Node):
4698 Streamline these. Simplify and improve efficiency. Move code
4699 from Allocate_Initialize_Node to these, where it can be executed
4700 unconditionally. Take advantage of automatic zeroing of the
4701 Nodes table.
4702 (Allocate_Initialize_Node): Remove this. It was an efficiency
4703 bottleneck, and somewhat complicated, because it was called from
4704 4 places, and had all sorts of conditionals to check where it
4705 was called from. Better to move most of that code to the call
4706 sites, where it can be executed (or not) unconditionally.
4707 (Allocate_New_Node): New procedure to partly replace
4708 Allocate_Initialize_Node (called from just 2 of those 4 places).
4709 (Comes_From_Source_Default): New flag written/read by
4710 Set_Comes_From_Source_Default/Get_Comes_From_Source_Default.
4711 This allows us to make Default_Node into a constant with
4712 all-zeros value.
4713 (Set_Paren_Count_Of_Copy): New procedure to avoid duplicated
4714 code.
4715 (Report): New procedure to encapsulate the call to the reporting
4716 procedure.
4717 (Atree_Private_Part): We now need a body for this package, to
4718 contain package body Nodes.
4719 (Approx_Num_Nodes_And_Entities): Was Num_Nodes. For efficiency,
4720 compute the answer from Nodes.Last. That way we don't need to
4721 increment a counter on every node creation. Other minor naming
4722 and comment changes.
4723 * gnat1drv.adb: Call Atree.Print_Statistics if -gnatd.A switch
4724 was given. Add comment documenting the new order dependency (we
4725 must process the command line before calling Atree.Initialize).
4726 * debug.adb: Document -gnatd.A.
4727 * einfo.adb, sinfo.adb: Remove useless Style_Checks pragmas.
4728 * nlists.ads (Allocate_List_Tables): Inline makes node creation
4729 a little faster.
4730 * nlists.adb (Initialize): Remove local constant E, which didn't
4731 seem to add clarity.
4732 * treepr.adb (Print_Init): Use renamed
4733 Approx_Num_Nodes_And_Entities function.
4734 * types.ads: Change the Low and High bounds as described above.
4735 * types.h: Change Low and High bounds to match types.ads.
4736 * sem_ch8.adb, namet.adb, namet.ads: Move the computation of
4737 Last_Name_Id from sem_ch8 to namet, and correct it to not assume
4738 Name_Ids are positive.
4739 * ali.adb, ali-util.adb, bindo-writers.adb, exp_dist.adb,
4740 fmap.adb, fname-uf.adb, osint.adb: Fix various hash functions to
4741 avoid assuming the various ranges are positive. Note that "mod"
4742 returns a nonnegative result when the second operand is
4743 positive. "rem" can return negative values in that case (in
4744 particular, if the first operand is negative, which it now is).
4745 * switch-c.adb: Allow switch -gnaten to control the value of
4746 Nodes_Size_In_Meg.
4747 * doc/gnat_ugn/building_executable_programs_with_gnat.rst:
4748 Remove traling whitespaces.
4749 * opt.ads (Nodes_Size_In_Meg): New Variable.
4751 2020-10-20 Eric Botcazou <ebotcazou@adacore.com>
4753 * exp_util.adb (Remove_Side_Effects): Always generate a renaming
4754 that is handled by the front-end in the case of an indexed or a
4755 selected component whose prefix has a nonstandard representation.
4757 2020-10-20 Pat Rogers <rogers@adacore.com>
4759 * doc/gnat_rm/the_gnat_library.rst: Add Ada.Task_Initialization.
4760 * gnat_rm.texi: Regenerate.
4762 2020-10-20 Yannick Moy <moy@adacore.com>
4764 * errout.adb: (Error_Msg-Internal): Pass the location for a line
4765 insertion if any in the message.
4766 (Output_Messages: Add display of source code lines if -gnatdF is
4767 set.
4768 (Write_Source_Code_Line): Code clean up.
4769 * erroutc.adb (Prescan_Message): Apply prescan for continuation
4770 lines when -gnatdF is set, and record presence of line
4771 insertion.
4772 * erroutc.ads (Has_Insertion_Line): New global for prescan.
4773 (Error_Msg_Object): Add field to record line insertion if
4774 present.
4775 * errutil.adb (Error_Msg): Pass no location for Insertion_Sloc.
4777 2020-10-20 Arnaud Charlet <charlet@adacore.com>
4779 * exp_ch5.adb (Expand_N_Case_Statement): Do not generate
4780 validity check when possible.
4782 2020-10-20 Ed Schonberg <schonberg@adacore.com>
4784 * exp_aggr.adb (Expand_Iterated_Component): Reorganize code to
4785 ensure that Loop_Id is properly initialized on all paths, and
4786 remove code duplication.
4788 2020-10-20 Piotr Trojanek <trojanek@adacore.com>
4790 * sem_ch3.adb (Analyze_Subtype_Declaration): Propagate predicate

4796 * exp_attr.adb (Expand_N_Attribute_Reference): Merge handling of
4797 Simple_Storage_Pool and Storage_Pool.
4799 2020-10-20 Piotr Trojanek <trojanek@adacore.com>
4801 * aspects.ads: Introduce Subprogram_Variant aspect with the

4814 which is stored in N_Contract node together with Contract_Cases.
4815 * contracts.ads (Analyze_Entry_Or_Subprogram_Contract): Mention
4816 new aspect in the comment.
4817 (Analyze_Entry_Or_Subprogram_Body_Contract): Likewise.

4824 recursive calls.
4825 * exp_prag.adb (Make_Op): Moved from expansion of pragma
4826 Loop_Variant to Exp_Util, so it is now reused for expansion of
4827 pragma Subprogram_Variant.
4828 (Process_Variant): Adapt call to Make_Op after moving it to
4829 Exp_Util.
4830 (Expand_Pragma_Subprogram_Variant): New routine.

4839 Contracts (see above).
4840 * sem.ads (Insert_Before_First_Source_Declaration): Likewise.
4841 * sem_ch12.adb: Mention new aspect in the comment about
4842 "Implementation of Generic Contracts", just like similar aspects
4843 are mentioned there.
4844 * sem_ch13.adb (Insert_Pragma): Mention new aspect in the
4845 comment, because this routine is now used for Subprogram_Variant
4846 just like for other similar aspects.
4847 (Analyze_Aspect_Specifications): Mention new aspect in comments;
4848 it is handled just like aspect Contract_Cases.
4849 (Check_Aspect_At_Freeze_Point): Do not expect aspect
4850 Subprogram_Variant just like we don't expect aspect
4851 Contract_Cases.
4852 * sem_prag.adb (Ensure_Aggregate_Form): Now also used for pragma
4853 Subprogram_Variant, so update comment.
4854 (Analyze_Pragma): Add initial checks for pragma
4855 Subprogram_Variant.
4856 (Analyze_Subprogram_Variant_In_Decl_Part): New routine with
4857 secondary checks on the new pragma.
4858 (Sig_Flags): Handle references within pragma Subprogram_Variant
4859 expression just like references in similar pragma
4860 Contract_Cases.

4880 Subprogram_Variant.
4882 2020-10-20 Piotr Trojanek <trojanek@adacore.com>
4884 * exp_util.ads: Reorder declaration.
4886 2020-10-19 Ed Schonberg <schonberg@adacore.com>
4888 * par-ch4.adb: (P_Aggregate_Or_Paren_Expr): Recognize
4889 Iterated_Element_Component.
4890 (P_Iterated_Component_Association): Rebuild node as an Iterated_
4891 Element_Association when Key_Expression is present, and attach

4894 * sem_aggr.adb: (Resolve_Container_Aggregate):
4895 Resolve_Iterated_Association handles bota Iterated_Component_
4896 and Iterated_Element_Associations, in which case it analyzes and
4897 resoles the orresponding Key_Expression.
4898 * exp_aggr.adb (Expand_Iterated_Component): If a Key_Expression
4899 is present, use it as the required parameter in the call to the
4900 insertion routine for the destination container aggregate. Call
4901 this routine for both kinds of Iterated_Associations.

4935 2020-10-19 Ed Schonberg <schonberg@adacore.com>
4937 * exp_ch6.adb (Add_View_Conversion_Invariants): Do not insert
4938 generated invariant checks when the call is a function call.
4939 These tests are properly inserted in the code in procedure
4940 Insert_Post_Call_Actions, which takes care of finding the proper

4942 (Insert_Post_Call_Actions): Add question marks to indicate
4943 possible gap in handling function calls that appear as aggregate
4944 components.

4972 of the whole object.
4973 (Mark_And_Set_Ghost_Assignment): Rewrite to use
4974 Whole_Object_Ref. We need to partly analyze the left-hand side
4975 in order to distinguish expanded names and record components.

5005 * sem_ch13.adb (Analyze_Aspect_Relaxed_Initialization): Fix bug
5006 where a call to Error_Msg_N leads to crash due to
5007 Error_Msg_Name_1 being removed by the call, while a subsequent
5008 call to Error_Msg_N tries to use it. The variable
5009 Error_Msg_Name_1 should be restored prior to the next call. Also
5010 add checking for the new rules.
5012 2020-10-19 Arnaud Charlet <charlet@adacore.com>
5014 * checks.adb (Apply_Type_Conversion_Checks): Minor code clean
5015 up.

5069 Ada.Strings.Text_Output, Ada.Strings.Text_Output.Utils, and
5070 System.Put_Images Pure, so they can be with'ed by Pure units
5071 that should have Put_Image defined.
5072 * libgnat/a-stouut.adb: Add missing column adjustments, and
5073 remove a redundant one.
5074 * libgnat/s-putima.adb (Put_Arrow): New routine to print an

5188 call P_Qualified_Expression. We don't need to modify other
5189 places that call P_Qualified_Expression, because a
5190 qualified_expression is a name in Ada 2012 and higher, so P_Name
5191 is the right place. The parser already parses aggregates with

5211 2020-10-16 Ed Schonberg <schonberg@adacore.com>
5213 * exp_imgv.adb (Expand_Image_Attribute): Use the base type
5214 instead of the root type when type of object is private. Remove
5215 Ada_2020 guard, because it has been checked during prior
5216 analysis. Use Underlying_Type in all cases, as it is a no-op on
5217 types that are not private.
5219 2020-10-16 Arnaud Charlet <charlet@adacore.com>

5242 nearest explicit discriminant constraint associated with a type
5243 that may possibly have inherited a constraint from an ancestor
5244 type.

5296 either a function call when the reducer is a function or an
5297 attribute, or a procedure call when reducer is an appropriate
5298 procedure. BuilD_Stat is used both when the prefix of 'Reduce

5469 Unnest_If_Statement to traverse a statement list looking for
5470 top-level subprogram bodies that require wrapping inside a
5471 procedure (via Unnest_Statement_List) as well as possibly having
5472 other statements (block, loop, if) that may themselves require
5473 an unnesting transformation (via
5474 Check_Unnesting_In_Decls_Or_Stmts).
5475 (Unnest_Statement_List): New support procedure to traverse the
5476 statements of a statement list that contains subprogram bodies
5477 at the top level and replace the statement list with a wrapper
5478 procedure body encapsulating the statements and a call to the
5479 procedure.

5585 for a static expression is unaffected by assertion policy (and,
5586 in particular, enabling/disabling of subtype predicates. To get
5587 the right legality checking, we need to call
5588 Check_Expression_Against_Static_Predicate for a static
5589 expression even if predicate checking is disabled for the given
5590 predicate-bearing subtype. On the other hand, we don't want to

5604 of a declared subtype using the 'Small of the type; this is
5605 done during resolution of the bound itself, unlike what is done
5606 for the bounds of the base type, which are used to determine its
5607 required size. Previous code performed this scaling twice,
5608 leading to meaningless values for such a subtype.

6059 appear in the visible part of its enclosing package when
6060 checking the overriding requirement of 7.3.2(6.1/4), as
6061 clarified by AI12-0382.

6102 * sem_ch13.ads (Same_Representation): Renamed as
6103 Has_Compatible_Representation because now the order of the arguments
6104 are taken into account; its formals are also renamed as Target_Type
6105 and Operand_Type.
6106 * sem_ch13.adb (Same_Representation): Renamed and moved to place the
6107 routine in alphabetic order.
6108 * sem_attr.adb (Prefix_With_Safe_Accessibility_Level): New subprogram.

6115 Same_Representation.
6116 (Expand_N_Type_Conversion): Update call to Same_Representation.

6130 2020-07-16 Javier Miranda <miranda@adacore.com>
6132 * exp_ch3.adb (Expand_N_Full_Type_Declaration): Ensure a _master
6133 declaration on limited types that might have tasks.
6134 * exp_ch9.adb (Build_Master_Renaming): For private types, if we
6135 are processing declarations in the private part, ensure that
6136 master is inserted before its full declaration; otherwise the
6137 master renaming may be inserted in the public part of the
6138 package (and hence before the declaration of its _master
6139 variable).
6141 2020-07-16 Arnaud Charlet <charlet@adacore.com>
6143 * sem_ch8.adb (Analyze_Subprogram_Renaming): A renames-as-body

6149 * sem_aggr.adb (Resolve_Container_Aggregate): Add semantic
6150 checks for indexed aggregates, including component associations
6151 and iterated component associations.

6153 subsidiary of Expand_Container_Aggreggate, used for positional,
6154 named, and indexed aggregates.
6155 (Aggregate_Size): New subprogram to precompute the size of an
6156 indexed aggregate prior to call to allocate it.
6157 (Expand_Range_Component): New subprogram so generate loop for a
6158 component association given by a range or a subtype name in an
6159 indexed aggregate.
6161 2020-07-16 Bob Duff <duff@adacore.com>
6163 * bindo-diagnostics.adb (Output_Invocation_Related_Suggestions):
6164 Use Cumulative_Restrictions.Set, because Restriction_Active only
6165 works at compile time.
6167 2020-07-16 Bob Duff <duff@adacore.com>
6169 * gnatbind.adb (Gnatbind): For No_Tasks_Unassigned_To_CPU, check
6170 that CPU has been set on the main subprogram.
6171 (Restriction_Could_Be_Set): Don't print
6172 No_Tasks_Unassigned_To_CPU if it would violate the
6173 above-mentioned rule. Up to now, all restrictions were checked
6174 by the compiler, with the binder just checking for consistency.
6175 But the compiler can't know which subprogram is the main, so
6176 it's impossible to check this one at compile time.
6177 * restrict.ads, restrict.adb: Misc refactoring. Change Warning
6178 to Warn, for consistency, since most already use Warn.
6179 (Set_Restriction): New convenience routine.
6180 * sem_ch13.adb (Attribute_CPU): Check

6193 * Makefile.rtl: replace a-numaux__x86.ads by
6194 a-numaux__libc-x86.ads and a-numaux__x86.adb by
6195 a-numaux__dummy.adb.
6196 * libgnat/a-numaux__x86.ads, libgnat/a-numaux__x86.adb: Removed.
6197 * libgnat/a-numaux__dummy.adb: New.
6199 2020-07-16 Ed Schonberg <schonberg@adacore.com>
6201 * sem_ch12.adb (Load_Parent_Of_Generic): If an ancestor is an
6202 instance whose source appears within a formal package of the
6203 current unit, there is no body of the ancestor needed to
6204 complete the current generic compilation.
6206 2020-07-16 Doug Rupp <rupp@adacore.com>
6208 * libgnat/s-thread__ae653.adb (taskVarAdd): Defunct, so remove.

6222 libgnat/a-wichha.adb, libgnat/a-wichha.ads,
6223 libgnat/a-wichun.adb, libgnat/a-wichun.ads,
6224 libgnat/a-zchhan.adb, libgnat/a-zchhan.ads,
6225 libgnat/a-zchuni.adb, libgnat/a-zchuni.ads (Is_NFKC): New.
6226 * libgnat/s-utf_32.ads, libgnat/s-utf_32.adb (Is_UTF_32_NFKC):
6227 New.
6229 2020-07-16 Bob Duff <duff@adacore.com>
6231 * libgnat/s-rident.ads (Restriction_Id): Add
6232 No_Tasks_Unassigned_To_CPU.
6234 2020-07-16 Bob Duff <duff@adacore.com>
6236 * exp_aggr.adb (Max_Aggregate_Size): Use the small size of 64
6237 when copying is needed (for example, for the initialization of a
6238 local variable, and for assignment statements). Use the larger
6239 size when static allocation can be done without copying.
6241 2020-07-16 Bob Duff <duff@adacore.com>
6243 * libgnat/s-rident.ads (No_Dynamic_CPU_Assignment): New
6244 restriction. Add it to all relevant profiles.
6245 * sem_ch13.adb (Attribute_CPU): Check No_Dynamic_CPU_Assignment
6246 restriction.
6247 (Attribute_CPU, Attribute_Dispatching_Domain,
6248 Attribute_Interrupt_Priority): Remove error checks -- these are
6249 checked in the parser.
6250 * sem_prag.adb (Pragma_CPU): Check No_Dynamic_CPU_Assignment
6251 restriction. We've got a little violation of DRY here.
6252 * sem.ads, sem_ch3.ads: Minor comment fix.
6254 2020-07-16 Gary Dismukes <dismukes@adacore.com>
6256 * sem_ch4.adb (Try_Container_Indexing): When the prefix type is
6257 an access type, change it to the designated type, change the
6258 prefix to an explicit dereference, and emit a ?d? warning for
6259 the implicit dereference. Include a ??? comment questioning
6260 whether this is the right context in which to perform the
6261 implicit dereferencing.
6263 2020-07-16 Arnaud Charlet <charlet@adacore.com>
6265 * sem_ch13.adb (Validate_Literal_Aspect): Ensure that the

6279 that the null exclusions match, including in the case addressed
6280 by this AI.
6281 (Check_Conformance): Remove calls to Comes_From_Source
6282 when calling Null_Exclusions_Match. These are not
6283 needed, as indicated by an ancient "???" comment.
6285 2020-07-16 Justin Squirek <squirek@adacore.com>
6287 * exp_ch4.adb (Expand_N_Type_Conversion): Remove flawed test for
6288 whether "statically deeper" accessibility rules apply to a given
6289 target type and instead use the new routine
6290 Statically_Deeper_Relation_Applies.
6291 (Statically_Deeper_Relation_Applies): Created to centralize the
6292 calculation of whether a target type within a conversion must
6293 have static accessibility checks.
6294 * sem_ch13.adb (Check_One_Function): Minor comment revision.
6296 2020-07-16 Eric Botcazou <ebotcazou@adacore.com>

6364 2020-07-16 Gary Dismukes <dismukes@adacore.com>
6366 * exp_ch4.adb (Expand_N_Type_Conversion): Handle the case of

6965 * exp_ch9.adb
6966 (Build_Class_Wide_Master): Insert the declaration of _Master

6980 * debug.adb: Document new switch.
6981 * exp_ch6.adb (Warn_BIP): New function that warns if the switch
6982 is on. Call it from Make_Build_In_Place_* functions. Warn_BIP
6983 is not needed in Make_Build_In_Place_Iface_*, because those call
6984 Make_Build_In_Place_Call_In_Object_Declaration or similar.
6986 2020-07-08 Piotr Trojanek <trojanek@adacore.com>
6988 * erroutc.adb (Matches): Fix comments.

7014 choice for byte-packed array types.
7016 2020-07-08 Piotr Trojanek <trojanek@adacore.com>
7018 * sem_attr.adb (Analyze_Attribute): Correct prefix of 'Result
7019 this prefix is a generic function but the enclosing aspect or
7020 pragma is attached to its instance.
7021 * sem_ch12.adb (Analyze_Generic_Subprogram_Declaration): Analyze
7022 generic subprogram formal parameters (including the implicit
7023 result of a generic function) and only then analyse its aspects,
7024 because with Relaxed_Initialization the aspect expression might
7025 refer to those formal parameters.
7026 * sem_ch13.adb (Analyze_Aspect_Relaxed_Initialization): Accept
7027 aspect on generic subprograms; install formal parameters of a
7028 generic subprogram but not formal parameters of the generic unit
7029 itself (the previous code was inspired by aspects Post and
7030 Depends, where both kinds of formals are allowed).
7031 * sem_util.ads (Enter_Name): Fix name of a subprogram referenced

7059 2020-07-08 Bob Duff <duff@adacore.com>
7061 * sem_ch13.adb (Predicate_Failure): Check that the type has
7062 predicates. Remove the setting of Has_Delayed_Aspects and
7063 Freeze_Node, because (if the code is legal) it should have
7064 already been done by the predicate aspect.
7066 2020-07-08 Gary Dismukes <dismukes@adacore.com>
7068 * par-ch4.adb (P_Iterated_Component_Association): Typo

7071 2020-07-08 Ed Schonberg <schonberg@adacore.com>
7073 * par.adb (P_Iterator_Specification): Make public for use in
7074 other parser subprograms.
7075 * par-ch4.adb (P_Iterated_Component_Association): In Ada_2020,
7076 recognize use of Iterator_Specification in an element iterator.
7077 To simplify disambiguation between the two iterator forms, mark
7078 the component association as carrying an Iterator_Specification
7079 only when the element iterator (using "OF") is used.
7080 * par-ch5.adb (P_Loop_Parameter_Specification): In Ada_2020,
7081 parse iterator filter when present.
7082 (P_Iterator_Specification): Ditto. Remove declaration of
7083 P_Iterator_Specification, now in parent unit.
7084 * exp_ch5.adb (Expand_N_Loop_Statement): Apply Iterator filter
7085 when present.
7086 (Expand_Iterator_Loop_Over_Array): Ditto.
7087 (Expand_Iterator_Loop_Over_Container): Ditto.
7088 * sem_aggr.adb (Resolve_Array_Aggregate): Emit error nessage if
7089 an iterated component association includes a iterator
7090 specificcation with an element iterator, i.e. one that uses the
7091 OF keyword.
7092 * sem_ch5.adb (Analyze_Iterator_Specification): Analyze Iterator
7093 filter when present.
7094 (Analyze_Loop_Parameter_Specification): Ditto.
7095 * sinfo.adb: Suprogram bodies for new syntactic element
7096 Iterator_Filter.
7097 * sinfo.ads: Add Iterator_Filter to relevant nodes. Structure
7098 of Component_Association and Iteroted_Component_Association
7099 nodes is modified to take into account the possible presence of
7100 an iterator specification in the latter.
7102 2020-07-08 Yannick Moy <moy@adacore.com>
7104 * sem_util.ads, sem_util.adb (Is_Attribute_Loop_Entry): New
7105 function for GNATProve.
7107 2020-07-08 Ghjuvan Lacambre <lacambre@adacore.com>
7109 * sem_ch13.adb (Analyze_Record_Representation_Clause,

7128 * exp_ch6.adb (Expand_Simple_Function_Return): Remove ugly code
7129 that was copying the return expression, resetting Analyzed
7130 flags, etc. for the return expression of static expression
7131 functions.
7132 * inline.adb (Inline_Static_Expression_Function_Call): Set the
7133 Parent of the copied expression to that of the call. This avoids
7134 a blowup in Insert_Actions when GNATprove_Mode is set and there
7135 are nested SEF calls. Add ??? comment.
7136 * sem_ch6.adb (Analyze_Expression_Function): In the case of a
7137 static expression function, create a new copy of the expression
7138 and replace the function's expression with the copy; the
7139 original expression is used in the expression function's body
7140 and will be analyzed and rewritten, and we need to save a clean
7141 copy for later use in processing static calls to the function.
7142 This allows removing the kludgy code that was in
7143 Expand_Simple_Function_Return.
7144 * sem_eval.adb (Eval_Qualified_Expression): Return immediately
7145 if any errors have been posted on the qualified expression, to
7146 avoid blowups when GNATprove_Mode is enabled (or with -gnatd.F),
7147 since illegal static expressions are handled differently in that
7148 case and attempting to fold such expressions would fail.
7150 2020-07-08 Eric Botcazou <ebotcazou@adacore.com>
7152 * repinfo.adb (Compute_Max_Length): Skip hidden discriminants.
7153 (List_Record_Layout): Likewise.
7154 (List_Structural_Record_Layout): Use First_Discriminant instead
7155 of First_Stored_Discriminant and Next_Discriminant instead of
7156 Next_Stored_Discriminant to walk the list of discriminants.

7184 for the Underlying_Full_View if it exists. The freeze node is
7185 what triggers the generation of the predicate function.
7186 * freeze.adb: Minor reformatting.
7188 2020-07-08 Eric Botcazou <ebotcazou@adacore.com>
7190 * exp_ch4.adb (Narrow_Large_Operation): Use the base type instead
7191 of the first subtype of standard integer types as narrower type.
7193 2020-07-07 Eric Botcazou <ebotcazou@adacore.com>
7195 * freeze.adb (Freeze_Array_Type): Use Ctyp more consistently.
7196 Move code setting the alignment in the non-packed case to...
7197 * layout.adb (Layout_Type): ...here.
7199 2020-07-07 Bob Duff <duff@adacore.com>
7201 * treepr.adb (Print_Node): Add code to test Is_Extension.
7203 2020-07-07 Arnaud Charlet <charlet@adacore.com>

7206 against malformed tree in case of errors.
7208 2020-07-07 Piotr Trojanek <trojanek@adacore.com>

7221 * sem_ch6.adb (Check_Formal_Subprogram_Conformance): New
7222 subprogram to handle checking without systematically emitting an
7223 error.
7224 (Check_Conformance): Update call to
7225 Check_Formal_Subprogram_Conformance and fix handling of Conforms
7226 and Errmsg parameters.
7228 2020-07-07 Arnaud Charlet <charlet@adacore.com>
7230 * exp_ch4.adb (Tagged_Membership): Generate a call to
7231 CW_Membership instead of using Build_CW_Membership.
7232 (Expand_N_In): Remove wrong handling of null access types and
7233 corresponding comment.
7234 * exp_intr.adb (Expand_Dispatching_Constructor_Call): Generate a
7235 call to CW_Membership instead of using Build_CW_Membership.
7236 * rtsfind.ads: Add CW_Membership.

7245 proper subprogram specification for body, using names in the
7246 subprogram declaration but distinct entities.
7247 * exp_ch6.adb (Expand_Call): If this is an indirect call
7248 involving a subprogram wrapper, insert pointer parameter in list
7249 of actuals with a parameter association, not as a positional
7250 parameter.
7252 2020-07-07 Justin Squirek <squirek@adacore.com>
7254 * exp_ch6.adb (Expand_Branch): Verify the original node is a
7255 conditional expression before recursing further.

7341 * restrict.ads (Check_Restriction_No_Specification_Of_Aspect):
7342 Mention possible new node kinds in documentation.
7343 * restrict.adb (Check_Restriction_No_Specification_Of_Aspect):
7344 Retrieve aspect id from different fields if given node is an
7345 N_Pragma or an N_Attribute_Definition_Clause.
7347 2020-07-07 Gary Dismukes <dismukes@adacore.com>
7349 * contracts.adb (Add_Invariant_And_Predicate_Checks): Relax the
7350 condition for doing invariant checks so that in-mode parameters
7351 of procedures are also checked (required by AI05-0289, and
7352 restricted to procedures by AI12-0044). This is done in a
7353 procedure's nested postconditions procedure.
7354 * exp_ch6.adb (Expand_Actuals): Also perform postcall invariant
7355 checks for in parameters of procedures (but not functions).
7356 Moved invariant-checking code to end of Expand_Actuals
7357 (including the nested function Is_Public_Subp).
7359 2020-07-07 Piotr Trojanek <trojanek@adacore.com>
7361 * sem_aggr.adb (Resolve_Delta_Array_Aggregate): Make Index_Type
7362 a constant.
7364 2020-07-07 Piotr Trojanek <trojanek@adacore.com>
7366 * exp_aggr.adb (Expand_N_Delta_Aggregate): Use type of the delta
7367 base expression for the anonymous object of the delta aggregate.
7369 2020-07-07 Javier Miranda <miranda@adacore.com>
7371 * sem_util.ads (Interval_Lists): Reordering routine.
7372 * sem_util.adb (Interval_Lists): Reordering routines to keep
7373 them alphabetically ordered.
7375 2020-07-07 Piotr Trojanek <trojanek@adacore.com>
7377 * sem_attr.adb (Resolve_Attribute): Do not call
7378 Check_Non_Static_Context.
7380 2020-07-07 Arnaud Charlet <charlet@adacore.com>
7382 * sem_elab.adb (Is_Guaranteed_ABE): Take into account null
7383 procedures.
7385 2020-07-07 Piotr Trojanek <trojanek@adacore.com>
7387 * sem_ch5.adb (Analyze_Assignment): Reuse Is_Assignable.
7389 2020-07-07 Piotr Trojanek <trojanek@adacore.com>
7391 * exp_spark.adb (Expand_SPARK_N_Attribute_Reference): Add scalar
7392 range checks for 'Update on arrays just like for 'Update on
7393 records.
7394 * sem_attr.adb (Analyze_Array_Component_Update): Do not set
7395 range checks for single-dimensional arrays.
7396 (Resolve_Attribute): Do not set range checks for both single-
7397 and multi- dimensional arrays.
7399 2020-07-07 Piotr Trojanek <trojanek@adacore.com>
7401 * sem.ads (Sem): Fix description.
7403 2020-07-07 Piotr Trojanek <trojanek@adacore.com>
7405 * sem_ch13.adb (Analyze_Relaxed_Parameter): Fix for protected
7406 entries.
7408 2020-07-06 Piotr Trojanek <trojanek@adacore.com>
7410 * checks.adb (Apply_Scalar_Range_Check): Use Is_RTE.
7412 2020-07-06 Bob Duff <duff@adacore.com>
7414 * libgnat/g-catiio.ads: Document newly supported format. Add
7415 ISO_Time constant, for convenience.
7416 * libgnat/g-catiio.adb (Image_Helper): New helper function to do
7417 all the formatting work, called by the two exported Image
7418 functions. Add support for "%:::z" here. Add a Time_Zone
7419 parameter used by the "%:::z" processing. This parameter is not
7420 used for the actual time zone computations; local time is always
7421 used for that, for ease of implementation reasons. It would
7422 make sense to use Append throughout this function, but that's a
7423 cleanup for another day.
7424 (Image): Modify these to pass the local time zone, or the
7425 specified time zone, as appropriate.
7427 2020-07-06 Bob Duff <duff@adacore.com>
7429 * libgnat/g-catiio.ads: Change the regular expression that
7430 documents the allowed format to match what ISO-8601 allows.
7431 * libgnat/g-catiio.adb (Scan_Subsecond): Rewrite so it doesn't
7432 assume the subsecond comes last.
7433 (Parse_ISO_8601): Parse an optional subsecond, followed by an
7434 optional time zone, rather than making these alternatives to
7435 each other.
7437 2020-07-06 Bob Duff <duff@adacore.com>
7439 * libgnat/g-catiio.adb (Parse_ISO_8601): Minor cleanups:
7440 Give some objects clearer names.
7441 Make some objects more local to where they are used.
7442 Remove some validity checks that can't fail, because some of
7443 the variables tested have been moved so they're not visible here.
7444 Anyway, Wrong_Syntax is about errors in the input, not data
7445 validity.
7446 Use Time_Zone_Seen instead of Local_Sign = ' ' to determine
7447 that a time zone indication was seen.
7448 We don't need to distinguish two different kinds of
7449 syntax error (End_Of_Source_Reached and Wrong_Syntax),
7450 so use Wrong_Syntax always.
7451 Remove comment, "Certain scanning scenarios may handle
7452 this exception on their own."; there are no such scenarios.
7454 2020-07-06 Bob Duff <duff@adacore.com>
7456 * libgnat/g-catiio.ads, libgnat/g-catiio.adb (Image): New
7457 function. It might seem like the local-time Image should be
7458 implemented in terms of the Time_Zone Image, but that would be
7459 far harder to implement, so we do it the other way around.
7461 2020-07-06 Thomas Quinot <quinot@adacore.com>
7463 * libgnat/g-sechas.ads, libgnat/g-sechas.adb: Refactor to use
7464 Stream_Element_Array as the internal buffer type.
7465 * libgnat/g-shshco.adb: Adjust to use Stream_Element_Offset
7466 instead of Integer as the index in the internal state buffer.
7468 2020-07-06 Gary Dismukes <dismukes@adacore.com>
7470 * doc/gnat_rm/implementation_defined_pragmas.rst, errout.ads,
7471 erroutc.adb, exp_ch4.adb, exp_ch6.adb, freeze.adb: Comment
7472 rewording/reformatting/typo fixes. Replace "ie." with "that is"
7473 in comment; "can not" -> "cannot", and remove an extraneous
7474 underscore in another comment.
7475 * gnat_rm.texi, gnat_ugn.texi: Regenerate.
7477 2020-07-06 Javier Miranda <miranda@adacore.com>
7479 * sem_util.ads (Interval_Lists.Aggregate_Intervals): New
7480 subprogram.
7481 * sem_util.adb (Has_Null_Others_Choice,
7482 Non_Static_Or_Null_Range, Interval_Lists.Aggregate_Intervals):
7483 New subprograms.
7484 (Is_Potentially_Unevaluated): Adding support to detect
7485 potentially unevaluated components of array aggregates.
7487 2020-07-06 Bob Duff <duff@adacore.com>
7489 * libgnat/g-catiio.adb (Parse_ISO_8601): New name for
7490 Parse_ISO_8861_UTC. 8601 is the correct ISO standard number.
7491 Also, "UTC" was confusing. All Time values are represented in
7492 UTC, but the ISO 8601 date strings include a time zone.
7493 If a time zone was specified, call
7494 Ada.Calendar.Formatting.Time_Of instead of
7495 GNAT.Calendar.Time_Of, because the latter adjusts to the current
7496 time zone, whereas we want to use (just) the time zone specified
7497 in the ISO string. This allows us to pass Time_Zone instead to
7498 Time_Of, instead of adjusting by Local_Disp by hand.
7499 If no time zone was specified, call GNAT.Calendar.Time_Of as
7500 before.
7501 Use expanded names to clarify which Time_Of is being called.
7502 Remove redundant comment, and move nonredundant part of the
7503 commment to the spec.
7504 (Value): Minor: use "not in" instead of "or else".
7505 * libgnat/g-catiio.ads: Comment moved here. Correct the ISO
7506 standard number.
7507 * libgnat/g-calend.adb: Add ??? comments.
7508 * libgnat/a-calend.ads, libgnat/a-calend.adb: Update obsolete
7509 comments regarding the representation of type Time. Move the
7510 information about the epoch (year 2150) to the spec, and avoid
7511 uttering "2150" more than once.
7512 * libgnat/a-catizo.ads (Time_Offset): Add comment.
7514 2020-07-06 Ed Schonberg <schonberg@adacore.com>
7516 * exp_ch5.adb (Find_Component): If the target type is a derived
7517 record type and the required component is a discriminant that is
7518 renamed in the derived type declaration, use the name of the
7519 original discriminant to locate the intended target component.
7521 2020-07-06 Justin Squirek <squirek@adacore.com>
7523 * sem_ch12.adb (Analyze_Associations): Add check for errors on
7524 the generic formal before continuing with instantiation.
7526 2020-07-06 Arnaud Charlet <charlet@adacore.com>
7528 * libgnat/a-nbnbin.ads, libgnat/a-nbnbin.adb,
7529 libgnat/a-nbnbin__gmp.adb: Use more Valid_Big_Integer.
7531 2020-07-06 Piotr Trojanek <trojanek@adacore.com>
7533 * exp_util.ads (Get_Index_Subtype): Fix duplicate "Last".
7535 2020-07-06 Ed Schonberg <schonberg@adacore.com>
7537 * sinfo.ads: Indicate that Field 1 of an N_Delta_Aggregate is
7538 unused. Previously it was erroneously labelled as holding an
7539 Expressions list, in analogy with other aggregate constructs,
7540 but there are no Expressions attached to this node syntactically
7541 or semantically.
7543 2020-07-06 Piotr Trojanek <trojanek@adacore.com>
7545 * sem_attr.adb (Eval_Attribute): Check if constant has an

7559 reference within an aspect of a type or subtype.
7560 (Address_Checks): Replace test of Is_Object (Ent) with
7561 Is_Object_Reference (P) so that testing for current instances
7562 will be done.
7563 (Eval_Attribute): Add test for current instance reference, to
7564 ensure that we still fold array attributes when current
7565 instances are involved, since value prefixes are allowed for
7566 array attributes, and will now be excluded by
7567 Is_Object_Reference.
7568 * sem_util.ads (Is_Current_Instance_Reference_In_Type_Aspect):
7569 New exported query function.
7570 * sem_util.adb (Is_Object_Reference): Return False for the case
7571 where N is a current instance reference within an
7572 aspect_specification of a type or subtype (basically if the
7573 reference occurs within a predicate, invariant, or DIC aspect
7574 expression).
7575 (Is_Current_Instance_Reference_In_Type_Aspect): New function
7576 that tests whether a node is a reference to a current instance
7577 formal of a predicate, invariant, or
7578 Default_Initial_Condition (DIC) subprogram.
7580 2020-07-06 Ed Schonberg <schonberg@adacore.com>
7582 * sem_res.adb (Resolve_Declare_Expression): New subprogram, to
7583 install the scope holding local declarations of the expression,
7584 before completing its resolution.
7585 (Resolve): For an Expression_With_Actions that comes from a
7586 source occurrence of a Declare_Expression, call new subprogram.

7609 * exp_ch6.adb (Add_Simple_Call_By_Copy_Code): Rename parameter
7610 from Bit_Packed_Array to Force.
7611 (Expand_Actuals): Do not apply BIP processing if the subprogram
7612 is intrinsic. Adjust calls to Add_Simple_Call_By_Copy_Code and
7613 add one for In parameters whose actual is a CPP constructor call.
7615 2020-07-06 Eric Botcazou <ebotcazou@adacore.com>
7617 * sem_attr.adb (Eval_Attribute): Do not apply range checks in
7618 the case of 'Pos applied to an integer type here.

7622 * sem_ch3.adb (Analyze_Object_Declaration): If the type is an
7623 Unchecked_Union, and the expression is an aggregate. complete
7624 the analysis and resolution of the aggregate, and treat like a
7625 regular object declaration, instead of as a renaming
7626 declarattion.
7628 2020-07-06 Eric Botcazou <ebotcazou@adacore.com>
7630 * exp_ch9.adb (Is_Potentially_Large_Family): Add documentation.

7653 level and use a new predicate Is_OK_Aggregate to recognize the
7654 aggregates suitable for direct assignment by the back-end.
7655 (Convert_Array_Aggr_In_Allocator): If neither in CodePeer mode nor
7656 generating C code, generate a direct assignment instead of further
7657 expanding if Aggr_Assignment_OK_For_Backend returns true.
7659 2020-07-06 Gary Dismukes <dismukes@adacore.com>
7661 * sem_aux.adb: Add a with clause for Nlists.
7662 (Nearest_Ancestor): Test for the case of concurrent
7663 types (testing for both Is_Concurrent_Type and
7664 Is_Concurrent_Record_Type), and return the first ancestor in the

7816 check that asserts the original source node being checked
7817 contains an entity. If not, it could be the result of special

8316 * freeze.adb (Check_Extra_Formals): New subprogram.
8317 (Freeze_Subprogram): Fix decoration of Extra_Formals.
8318 * sem_ch3.adb (Derive_Subprogram): Fix decoration of
8319 Extra_Formals.
8321 2020-06-17 Bob Duff <duff@adacore.com>
8323 * par.adb (P_Basic_Declarative_Items): Update comment about
8324 Declare_Expression.
8325 * par-ch3.adb (P_Declarative_Items): Pass in Declare_Expression
8326 flag, and if True, skip the call to Style.Check_Indentation.

8340 Apply_Length_Check to generate a length check.
8341 * sem_ch5.adb (Analyze_Assignment): Likewise.
8343 2020-06-17 Piotr Trojanek <trojanek@adacore.com>

8351 Adjust comments; support queries for constants.
8353 2020-06-17 Eric Botcazou <ebotcazou@adacore.com>
8355 * cstand.adb (Stloc): Change to a renaming.
8356 (Staloc): Likewise.
8357 (Build_Unsigned_Integer_Type): Remove Nam parameter, use local
8358 constants and do not call Make_Name.
8359 (Make_Dummy_Index): Use local constants.
8360 (Create_Standard): Pass the name of entities as parameter in
8361 calls to New_Standard_Entity and remove calls to Make_Name.

8375 2020-06-17 Eric Botcazou <ebotcazou@adacore.com>
8377 * exp_attr.adb (Expand_N_Attribute_Reference) <Attribute_First>:
8378 Remove condition added for scalar types.
8380 2020-06-17 Gary Dismukes <dismukes@adacore.com>

8387 comment and reformat comment in body.
8388 (Analyze_Full_Type_Declaration): Reformat comment.
8389 (Replace_Type_Name): Fixed three typos, plus reformatting of

8393 remove hyphen, add missing word.
8395 2020-06-17 Bob Duff <duff@adacore.com>
8397 * libgnat/a-cbdlli.adb, libgnat/a-cbhama.adb,
8398 libgnat/a-cbhase.adb, libgnat/a-cbmutr.adb,
8399 libgnat/a-cborma.adb, libgnat/a-cborse.adb,

8410 checks earlier.
8412 2020-06-17 Eric Botcazou <ebotcazou@adacore.com>
8414 * exp_attr.adb (Get_Integer_Type): Use standard types without
8415 a specific size.
8416 * sem_res.adb (Resolve_Unchecked_Type_Conversion): Remove a
8417 redundant intermediate conversion to Universal_Integer.
8419 2020-06-17 Piotr Trojanek <trojanek@adacore.com>
8421 * sem_util.ads, sem_util.adb (Get_Iterable_Type_Primitive): Fix
8422 comment and enforce it with an assertion in the body.
8424 2020-06-17 Ed Schonberg <schonberg@adacore.com>
8426 * sem_ch3.adb (Analyze_Full_Type_Declaration): For an
8427 access_to_subprogram declaration that has aspect specifications,
8428 call Build_Access_ Subprogram_Wrapper at once, so that pre- and
8429 postcondition aspects are analyzed in the context of a
8430 subprogram declaration.
8431 (Build_Access_Subprogram_Wrapper): Examine aspect specifications
8432 of an Access_To_Subprogram declaration. If pre- or
8433 postconditions are declared for it, create declaration for
8434 subprogram wrapper and add the corresponding aspect
8435 specifications to it. Replace occurrences of the type name by
8436 that of the generated subprogram, so that attributes 'Old and
8437 'Result can appear in a postcondition.
8438 * exp_ch3.adb (Build_Access_Subprogram_Wrapper_Body): Moved
8439 here from sem_prag.adb.
8440 * exp_ch3.ads (Build_Access_Subprogram_Wrapper_Body): Visible
8441 subprogram.
8442 * sem_prag.adb (Build_Access_Subprogram_Wrapper / _Body): Moved
8443 to sem_ch3.adb and exp_ch3.adb.
8445 2020-06-17 Piotr Trojanek <trojanek@adacore.com>
8447 * atree.adb (Preserve_Comes_From_Source): Rewrite using
8448 Set_Comes_From_Source and Comes_From_Source, which enforce that
8449 the parameters are valid.
8450 * exp_ch4.adb, exp_ch5.adb, sem_ch12.adb, sem_ch6.adb,
8451 sem_res.adb: Rewrite using Preserve_Comes_From_Source.
8453 2020-06-17 Arnaud Charlet <charlet@adacore.com>
8455 * libgnat/a-nbnbin.ads, libgnat/a-nbnbre.ads: Remove obsolete
8456 comments.
8458 2020-06-17 Gary Dismukes <dismukes@adacore.com>
8460 * aspects.ads (type Aspect_Id): Add Aspect_Static as a Boolean
8461 aspect, and update the Is_Representation_Aspect, Aspect_Names,
8462 and Aspect_Delay arrays.
8463 * exp_ch6.adb (Expand_Simple_Function_Return): In the case of a
8464 return for a static expression function, capture a copy of the
8465 expression of the return statement before it's expanded and
8466 reset its Analyzed flags. Then, just before leaving this
8467 procedure, if the expression was rewritten, set the
8468 Original_Node of the rewritten expression to the new copy and
8469 also set the Expression of the associated static expression
8470 function to designate that copy. This ensures that later copies
8471 of the expression made via New_Copy_Tree will fully copy all
8472 nodes of the expression tree.
8473 * inline.ads (Inline_Static_Expression_Function_Call): New
8474 procedure to evaluate and produce the result of a static call to
8475 a static expression function.
8476 * inline.adb: Add with and use for Sem_Res.
8477 (Establish_Actual_Mapping_For_Inlined_Call): New procedure
8478 extracted from code in Expand_Inlined_Call that traverses the
8479 actuals and formals of an inlined call and in some cases creates
8480 temporaries for holding the actuals, plus establishes an
8481 association between formals and actuals (via the Renamed_Object
8482 fields of the formals).
8483 (Formal_Is_Used_Once): Function removed from Expand_Inlined_Call
8484 and now nested in the above procedure.
8485 (Expand_Inlined_Call): Code for doing the formal/actual
8486 traversal is moved to Create_Actual_Temporaries and replaced
8487 with a call to that new procedure.
8488 (Inline_Static_Expression_Function_Call): New procedure to
8489 evaluate a static call to a static expression function,
8490 substituting actuals for their corresponding formals and
8491 producing a fully folded and static result expression. The
8492 function has subsidiary functions Replace_Formal and Reset_Sloc
8493 that take care of doing the mapping of formals to actuals and
8494 resetting the Slocs of subnodes of the mapped expression to that
8495 of the call so errors will be flagged on the call rather than
8496 function.
8497 * sem_ch6.adb (Analyze_Expression_Function): In the case of a
8498 static expression function, perform an additional preanalysis of
8499 the function's expression to ensure that it's a potentially
8500 static expression (according to the requirements of
8501 6.8(3.2/5-3.4/5)), and issue an error if it's not. The global
8502 flag Checking_Potentially_Static_Expression is set and unset
8503 around this checking.
8504 * sem_ch13.adb (Analyze_Aspect_Static): New procedure to enforce
8505 selected requirements of the new aspect Static on expression
8506 functions, including checking that the language version is
8507 Ada_2020 and that the entity to which it applies is an
8508 expression function whose formal parameters are of a static
8509 subtype and have mode 'in', its result subtype is a static
8510 subtype, and it has no pre- or postcondition aspects. A ???
8511 comment is added to indicate the need for adding checking that
8512 type invariants don't apply to the result type if the function
8513 is a boundary entity.
8514 (Analyze_One_Aspect): Call Analyze_Aspect_Static for aspect
8515 Static.
8516 * sem_elab.adb (Build_Call_Marker): Return without creating a
8517 call marker when the subprogram is a static expression function,
8518 since no ABE checking is needed for such functions.
8519 * sem_eval.ads (Checking_Potentially_Static_Expression): New
8520 function to return whether the checking for potentially static
8521 expressions is enabled.
8522 (Set_Checking_Potentially_Static_Expression): New procedure to
8523 enable or disable checking of potentially static expressions.
8524 * sem_eval.adb (Checking_For_Potentially_Static_Expression): New
8525 global flag for determining whether preanalysis of potentially
8526 static expression is being done, which affects the behavior of
8527 certain static evaluation routines.
8528 (Checking_Potentially_Static_Expression): New function to return
8529 whether the checking for potentially static expressions is
8530 enabled.
8531 (Eval_Call): When evaluating a call within a static expression
8532 function with checking of potentially static expression
8533 functions enabled, substitutes a static value in place of the
8534 call to allow folding of the expression.
8535 (Eval_Entity_Name): When evaluating a formal parameter of a
8536 static expression function with checking of potentially static
8537 expression functions enabled, substitutes a static value in
8538 place of the reference to the formal to allow folding of the
8539 expression.
8540 (Set_Checking_Potentially_Static_Expression): New procedure to
8541 enable or disable checking of potentially static expressions.
8542 * sem_res.adb (Resolve_Call): Test for a recursive call
8543 occurring within a static expression function and issue an error
8544 for such a call. Prevent the establishment of a transient scope
8545 in the case this is a call to a (string-returning) static
8546 expression function. When calling a static expression function,
8547 if no error has been posted on the function, call
8548 Inline_Static_Expression_Function_Call to convert the call into
8549 its equivalent static value.
8550 * sem_util.ads (Is_Static_Expression_Function): New function
8551 returning whether the subprogram entity passed to it is a static
8552 expression function.
8553 (Is_Static_Expression_Function_Call): New function to determine
8554 whether the call node passed to it is a static call to a static
8555 expression function.
8556 * sem_util.adb (Compile_Time_Constraint_Error): Suppress
8557 compile-time Constraint_Error reporting when checking for a
8558 potentially static expression.
8559 (Is_Static_Expression_Function): New function returning whether
8560 the subprogram entity passed to it is a static expression
8561 function by testing for the presence of aspect Static.
8562 (Has_All_Static_Actuals): New function in
8563 Is_Static_Expression_Function_Call that traverses the actual
8564 parameters of a function call and returns True only when all of
8565 the actuals are given by static expressions. In the case of a
8566 string-returning function, we call Resolve on each actual to
8567 ensure that their Is_Static_Expression flag properly reflects
8568 whether they're static, to allow suppressing creation of a
8569 transient scope within Resolve_Call. A prominent ??? comment is
8570 added to explain this rather unconventional call to Resolve.
8571 (Is_Static_Expression_Function_Call): New function that
8572 determines whether a node passed to it is a call to a static
8573 expression function all of whose actual parameters are given by
8574 static expressions.
8576 2020-06-17 Eric Botcazou <ebotcazou@adacore.com>
8578 * exp_ch4.adb (Optimize_Length_Comparison): New local variable to
8579 record whether this may be a dynamic superflat case.
8580 (Is_Optimizable): Accept 0 as lower bound and set it in this case,
8581 but return false if the operand is not a length too.
8582 (Rewrite_For_Equal_Lengths): New procedure.
8583 Optimize the comparison of two lengths in the superflat case when
8584 the arrays have the same bounds.
8586 2020-06-17 Eric Botcazou <ebotcazou@adacore.com>
8588 * doc/gnat_rm/implementation_defined_attributes.rst (Bit): Sharpen
8589 the comparison with System.Storage_Unit.
8590 (Descriptor_Size): Clear confusion about alignment and padding.
8591 * gnat_rm.texi: Regenerate.
8593 2020-06-17 Eric Botcazou <ebotcazou@adacore.com>
8595 * exp_attr.adb (Expand_N_Attribute_Reference) <Attribute_First>:
8596 Do not replace the bound for an array type if it is public.
8598 2020-06-17 Eric Botcazou <ebotcazou@adacore.com>
8600 * exp_ch4.adb (Optimize_Length_Comparison): Make sure the base
8601 types are the same when comparing Y'Last and X'Last directly.
8603 2020-06-17 Eric Botcazou <ebotcazou@adacore.com>
8605 * exp_attr.adb (Expand_N_Attribute_Reference) <Attribute_First>:
8606 Replace it with a direct reference to an entity which is not a
8607 discriminant for constrained array types. Add same condition
8608 for scalar types.
8609 <Attribute_Last>: Merge with above implementation.
8610 * exp_ch4.adb (Optimize_Length_Comparison): Be prepared for a
8611 second entity whose length is compared. Rename Prepare_64 to
8612 Convert_To_Long_Long_Integer. If the second entity is present,
8613 compute the difference of the 'First attributes and compare the
8614 sum of 'Last of the second entity with this difference against
8615 'Last of the first entity. Add a special case when the 'First
8616 attributes are equal. Suppress overflow checks in all cases.
8618 2020-06-17 Piotr Trojanek <trojanek@adacore.com>
8620 * doc/gnat_rm/implementation_defined_pragmas.rst, lib-writ.ads,
8621 par-prag.adb, sem_ch12.adb, sem_ch8.adb, sem_prag.adb: Fix
8622 casing of GNATprove.

8630 Likewise.
8631 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Likewise.
8633 2020-06-17 Eric Botcazou <ebotcazou@adacore.com>
8635 * exp_fixd.adb (Build_Conversion): Also preserve the
8636 Conversion_OK flag of an inner conversion.
8638 2020-06-17 Piotr Trojanek <trojanek@adacore.com>
8640 * sem_ch5.adb (Analyze_Iterator_Specification): Enable expansion
8641 that creates a renaming that removes side effects from the
8642 iterated object in the GNATprove mode; then analyze reference to
8643 this renaming (it is required for GNATprove and harmless for
8644 GNAT).
8646 2020-06-16 Eric Botcazou <ebotcazou@adacore.com>
8648 * sinfo.ads (Conversion_OK): Document use for 'Pos and 'Val.
8649 * exp_attr.adb (Get_Integer_Type): New function returning a
8650 small integer type appropriate for an enumeration type.
8651 (Expand_N_Attribute_Reference) <Attribute_Enum_Rep>: Call it.
8652 <Attribute_Pos>: For an enumeration type with a standard
8653 representation, expand to a conversion with Conversion_OK.
8654 <Attribute_Val>: Likewise.
8655 * exp_ch4.adb (Expand_N_Type_Conversion): Do not expand when
8656 the target is an enumeration type and Conversion_OK is set.
8658 2020-06-16 Eric Botcazou <ebotcazou@adacore.com>
8660 * sem_ch4.adb (Common_Type): Go to Underlying_Full_View, if any.

8677 sem_ch4.adb, sem_ch5.adb, urealp.adb: Fix wrong casing.
8678 * gnat_ugn.texi: Regenerate.
8680 2020-06-16 Piotr Trojanek <trojanek@adacore.com>
8682 * einfo.adb, exp_spark.adb, exp_util.adb, sem_eval.adb: Replace
8683 "Ekind ... in Object_Kind" with "Is_Object (...)".
8685 2020-06-16 Piotr Trojanek <trojanek@adacore.com>
8687 * sem_warn.adb (Warn_On_Overlapping_Actuals): Fix typo in

8695 indexed component.
8697 2020-06-16 Eric Botcazou <ebotcazou@adacore.com>
8699 * freeze.adb (Freeze_Expression): Use consistent style and
8700 formatting in a couple of cases.
8702 2020-06-16 Steve Baird <baird@adacore.com>

8705 commented-out Integer_Literal aspect specification for type
8706 Big_Integer.
8708 2020-06-16 Javier Miranda <miranda@adacore.com>
8710 * exp_ch6.adb (BIP_Suffix_Kind, Check_BIP_Actuals,
8711 Is_Build_In_Place_Entity): New subprograms.
8712 (Make_Build_In_Place_Call_In_Allocator,
8713 Make_Build_In_Place_Call_In_Anonymous_Context,
8714 Make_Build_In_Place_Call_In_Assignment,
8715 Make_Build_In_Place_Call_In_Object_Declaration): Add assertions.
8716 (Needs_BIP_Task_Actuals): Add missing support for thunks.
8717 (Expand_Actuals): Ensure that the BIP call has available an
8718 activation chain and the _master variable.
8719 * exp_ch9.adb (Find_Enclosing_Context): Initialize the list of
8720 declarations of empty blocks when the _master variable must be
8721 declared and the list was not available.
8723 2020-06-16 Bob Duff <duff@adacore.com>
8725 * par-ch4.adb (P_Case_Expression): Move to be local.
8726 (P_Declare_Expression): New parsing routine.
8727 (P_Unparen_Cond_Expr_Etc): New name for
8728 P_Unparen_Cond_Case_Quant_Expression which was missing one case
8729 in its name (iterated component association), and we're adding a
8730 new case (declare expression), so lets use "Etc" instead of
8731 trying to pack all those things into the name. Add call to
8732 P_Declare_Expression, and check for missing parens.
8733 (P_Expression_If_OK, P_Expression_Or_Range_Attribute_If_OK): Add
8734 Tok_Declare.
8735 * par.adb (P_Basic_Declarative_Items): Add parameter
8736 Declare_Expression so we can tailor the error message about
8737 incorrect bodies.
8738 (P_Case_Expression): Move to body.
8739 * par-ch3.adb (P_Basic_Declarative_Items): Tailor the error
8740 message about incorrect bodies.
8741 * par-ch7.adb (P_Package): Pass Declare_Expression => False to
8742 P_Basic_Declarative_Items.
8743 * sem.ads (In_Declare_Expr): Counter used to determine whether
8744 we are analyzing a declare_expression. Needed to give errors
8745 about things that are not allowed in declare_expression, such as
8746 the 'Access attribute.
8747 * sem.adb (Do_Analyze): Save/restore In_Declare_Expr.
8748 * sem_ch4.adb (Analyze_Expression_With_Actions): Give this node
8749 its own scope. That seems better in general, but it is
8750 necessary for declare_expressions. For example, an identifier
8751 declared in a declare_expression should not clash with the same
8752 identifier in an outer scope. If this is a declare_expression,
8753 indicated by Comes_From_Source, then check legality rules, and
8754 incr/decr In_Declare_Expr.
8755 * sem_aggr.adb (Resolve_Aggregate): Allow an applicable index
8756 constraint for a declare_expression, so if its expression is an
8757 array aggregate, it can have "others => ...".
8758 * sem_attr.adb (Analyze_Access_Attribute): Disallow these
8759 attributes in declare_expressions. Add comment to make it clear
8760 that Unrestricted_Access is included.
8761 * sinfo.ads, sinfo.adb, atree.ads, atree.adb: Remove the
8762 now-incorrect comment in sinfo.ads that says
8763 N_Expression_With_Actions has no proper scope. Add 17-parameter
8764 versions of Nkind_In. Remove the 16-parameter versions of
8765 Nkind_In.
8767 2020-06-16 Arnaud Charlet <charlet@adacore.com>
8769 * sem_aux.ads, sem_aux.adb (Is_Record_Or_Limited_Type): New
8770 function.
8771 * exp_ch4.adb, sem_ch4.adb (Analyze_Membership_Op,
8772 Expand_Set_Membership.Make_Cond): Choose between primitive and
8773 predefined equality for membership tests.
8775 2020-06-16 Ed Schonberg <schonberg@adacore.com>
8777 * sem_warn.adb (Warn_On_Overlapping_Actuals): Simplify code and
8778 implement AI12-0216 which clarifies the conditions under which
8779 overlapping actuals in a call are illegal. If proper warnings
8780 are enabled, GNAT also emits warnings in legal cases of
8781 overlopping actuals.
8783 2020-06-16 Eric Botcazou <ebotcazou@adacore.com>
8785 * freeze.adb (Freeze_Expression): Stop climbing the parent chain
8786 at a N_{Case,If}_Expression node for a type or an entity that

8793 * sem_util.ads, sem_util.adb, sem_dim.adb: Move the function
8794 String_From_Numeric_Literal from being declared in the body of
8795 package Sem_Dim to being declared in the visible part of package
8796 Sem_Util.
8797 * sem_ch13.ads, sem_ch13.adb: Declare new visible procedure
8798 Validate_Literal_Aspect. This is where most of the legality
8799 checking occurs for an aspect specification for one of the three
8800 new aspects, as well as resolution of the subprogram named in
8801 the aspect specification. Follow example of other aspects (e.g.,
8802 Validate_Literal_Aspect is called in much the same way as
8803 Validate_Iterable_Aspect in Analyze_Aspects_At_Freeze_Point; a
8804 small amount of legality checking is performed in
8805 Analyze_One_Aspect in much the same way as for Default_Value or
8806 Default_Component_Value aspects). Most of the work is done in
8807 Validate_Literal_Aspect.
8808 * contracts.adb (Add_Contract_Item): Call
8809 Validate_Literal_Aspect in much the same way that
8810 Validate_Iterable_Aspect was already being called.
8811 * sem_res.adb (Resolve): Rewrite a literal as a call if it is a
8812 user-defined literal. This is where the dynamic semantics of
8813 the 3 new aspects are implemented.

8815 literals that have different text but the same value (e.g.,
8816 12345 and 12_345) do not conform if they are user-defined
8817 literals. Introduce a new function
8818 User_Defined_Numeric_Literal_Mismatch to avoid duplication in
8819 making this check.
8820 * sem_type.adb (Has_Compatible_Type): A numeric literal can be
8821 compatible with a non-numeric type (and a string literal can be
8822 compatible with a non-string type) if it can be interpreted as a
8823 user-defined literal.
8825 2020-06-16 Arnaud Charlet <charlet@adacore.com>
8827 * sem_aggr.adb (Resolve_Extension_Aggregate): Fix implementation

8844 2020-06-16 Arnaud Charlet <charlet@adacore.com>
8846 * sem_ch4.adb (Analyze_Membership_Op): Reset entity of equality
8847 nodes for membership tests with singletons.
8848 (Analyze_User_Defined_Binary_Op): Always perform the analysis
8849 since nodes coming from the expander also may refer to non
8850 standard operators as part of membership expansion.
8851 * exp_ch4.adb (Expand_Set_Membership.Make_Cond): Reset entity of
8852 equality node.
8853 * sem_type.ads: Fix typo in comment.
8855 2020-06-16 Ghjuvan Lacambre <lacambre@adacore.com>
8857 * sem_attr.adb (Analyze_Attribute): Add
8858 Check_Not_Incomplete_Type call.

8862 * sem_ch6.adb: Add closing paren in a comment.
8863 * sem_util.adb: Correct comment typo (aggreate => aggregate).

8886 Targparm.Restrictions_On_Target Fixes regressions with zfp.
8888 2020-06-16 Ed Schonberg <schonberg@adacore.com>
8890 * freeze.adb: (Freeze_Expression, In_Expanded_Body): Treat the
8891 generated body of an expression function like other bodies
8892 generated during expansion (e.g. stream subprograms) so that
8893 those bodies are not treated as freezing points. Handle properly
8894 other global references in such completions.
8896 2020-06-16 Piotr Trojanek <trojanek@adacore.com>
8898 * sem_ch8.adb (Analyze_Object_Renaming): Remove trivially
8899 useless initialization of Is_Object_Reference.
8900 * sem_util.adb (Is_Object_Reference): Simplify detection of
8901 binary and unary operators; literally implement rules about
8902 aggregates and qualified expressions; recognize string literals
8903 as object references.
8905 2020-06-16 Eric Botcazou <ebotcazou@adacore.com>
8907 * sem_ch12.adb (Validate_Derived_Type_Instance): Reword error
8908 message for 12.5.1(8) subclause and add secondary message if
8909 the incompatibility comes from the predicates.
8910 * sem_ch3.adb (Check_Constraining_Discriminant): New procedure
8911 to give the error required by the 3.7(15) subclause. Mention
8912 "statically" in the error message and add secondary message
8913 if the incompatibility comes from the predicates.
8914 (Build_Derived_Concurrent_Type): Call it when a new discriminant
8915 constrains an old one.
8916 (Build_Derived_Record_Type): Likewise.
8917 * sem_eval.ads (Predicates_Compatible): Declare.

8954 Call Apply_CW_Accessibility_Check to apply the check prescribed by
8955 AI95-344, but do not do it for the simple return statement generated
8956 by the expansion of an extended return statement. Apply the check
8957 prescribed by AI05-0073 to all functions returning anonymous access
8958 type designating a specific tagged type, but not if the expression
8959 was null or tag checks are suppressed for the type, and use Not In
8960 operator rather than comparing the tags explicitly.
8961 * sem.adb (Analyze): Handle all Suppress values.
8962 * sem_ch6.adb (Analyze_Function_Return): Do not explicitly apply
8963 predicate checks in the case of an extended return statement.

8974 the call to Put_Image should be generated.
8975 (Build_Image_Call): New procedure to generate the call to
8976 Put_Image.
8977 * exp_imgv.adb (Expand_Image_Attribute): Use underlying types to
8978 bypass privacy (only in Ada 2020). If
8979 Image_Should_Call_Put_Image is True (which happens only in Ada
8980 2020), then call Build_Image_Call.

9092 conversion passed to a scalar out-mode parameter where the
9093 formal has Default_Value set, declare the copy temp with the
9094 base type of the formal's subtype and initialize the copy temp
9095 with the actual's value.
9097 2020-06-15 Justin Squirek <squirek@adacore.com>
9099 * exp_ch4.adb (Expand_N_Case_Expression): Set default value for
9100 Target to silence potential warnings.
9101 (Expand_N_If_Expression): Add calculation to check when the if
9102 expression is used directly in the context of an actual of an
9103 anonymous access type and add a special path to force expansion

9106 level temporary for a given branch.
9107 (Expand_Call_Helper): Add expansion to allow for creating a
9108 temporary to store associated accessiblity levels on each branch
9109 of the conditional expression. Also perform expansion of
9110 function calls into expressions with actions, and fixup
9111 references to N with Call_Node.
9112 (Insert_Level_Assign): Move through nested conditional
9113 expressions to each branch.
9114 * sem_util.ads, sem_util.adb (Is_Anonymous_Access_Actual): Added
9115 to detect when to force expansion of if expressions.
9117 2020-06-15 Piotr Trojanek <trojanek@adacore.com>

9142 especially since they don't make the code any easier to read.
9144 2020-06-15 Piotr Trojanek <trojanek@adacore.com>
9146 * aspects.ads (Aspect_Id): Add Aspect_Relaxed_Initialization.

9156 query; reuses existing code for querying abstract state options.
9157 * exp_attr.adb (Expand_N_Attribute_Reference): For now ignore
9158 attribute 'Initialized.
9159 * sem_attr.adb (Analyze_Attribute_Old_Result): Allow attribute
9160 'Result to be used in the aspect Relaxed_Initialization
9161 expression.
9162 (Analyze_Attribute): Analyze attribute 'Initialized; based on
9163 existing code for attribute 'Valid_Scalars.
9164 (Eval_Attribute): Do not expect attribute 'Initialized, just
9165 like attribute 'Valid_Scalars is not expected.
9166 * sem_ch13.adb (Analyze_Aspect_Relaxed_Initialization): New
9167 routine.
9168 (Analyze_Aspect_Specifications): Analyze new aspect in a
9169 dedicated routine.

9176 attribute; add an Attribute_Id for the new attribute.
9178 2020-06-15 Bob Duff <duff@adacore.com>
9180 * exp_put_image.adb, libgnat/s-putima.adb, libgnat/s-putima.ads,
9181 rtsfind.ads: Enable Put_Image if Is_Access_Subprogram_Type (Typ).
9182 Remove comment saying it's disabled in that case. Rename
9183 Put_Image_Access_Prot to be Put_Image_Access_Prot_Subp to
9184 clarify that we're talking about access-to-subprogram, not
9185 access-to-protected-object.
9187 2020-06-15 Bob Duff <duff@adacore.com>
9189 * sem_attr.adb (Check_Image_Type): New procedure for checking
9190 the type, depending on language version. Disable the Ada 2020
9191 support until the corresponding expander work is done.
9192 (Analyze_Image_Attribute): Call Check_Image_Type. Rearrange the
9193 code to be simplier and more logical. When P_Type is modified,
9194 modify P_Base_Type accordingly.
9195 * sem_util.adb (Is_Object_Image): Do not return False if the
9196 prefix is a type. X'Image should be considered an image of an
9197 object iff X is an object (albeit illegal pre-2020 if
9198 nonscalar).
9200 2020-06-15 Bob Duff <duff@adacore.com>
9202 * libgnat/s-putima.ads, libgnat/s-putima.adb
9203 (Put_Image_Access_Subp, Put_Image_Access_Prot): New procedures
9204 for printing access-to-subprogram objects. Remove an explicit
9205 " ", because Put_Image includes the annoying leading blank.

9209 2020-06-15 Bob Duff <duff@adacore.com>
9211 * exp_imgv.adb (Expand_Image_Attribute): Allow private types.
9212 Put_Image generates Image for numeric types, and private types
9213 whose full type is numeric. This requires the Conversion_OK flag
9214 for integer and floating-point types. For fixed point, we need
9215 the extra conversion.
9216 * exp_put_image.adb (Build_Elementary_Put_Image_Call): Remove
9217 special handling of real types.
9218 (Enable_Put_Image): Enable for reals.
9220 2020-06-15 Bob Duff <duff@adacore.com>

9223 Remove unchecked union processing.
9224 * exp_put_image.adb (Tagged_Put_Image_Enabled): Use -gnatd_z to
9225 enable default Put_Image for tagged types. This allows testing
9226 that feature.
9227 (Build_String_Put_Image_Call): Set Conversion_OK flag.
9228 (Make_Component_List_Attributes): Remove unchecked union
9229 processing.
9230 (Enable_Put_Image): Disable for unchecked unions. Enable for
9231 nonscalar types (which were mistakenly disabled in earlier
9232 changes).
9233 * debug.adb: Document -gnatd_z switch.
9234 * libgnat/s-putima.adb (Put_Image_String, Put_Image_Wide_String,
9235 Put_Image_Wide_Wide_String): Double double-quote characters.
9236 Forget about special handling of control characters for now --
9237 that's rare enough to not be a priority, and it's not clear what
9238 the right thing to do is anyway.
9239 * namet.adb: Minor: Improve debugger-friendliness.
9240 * sinfo.ads: Minor: Add "???" comment.
9242 2020-06-15 Piotr Trojanek <trojanek@adacore.com>
9244 * sem_util.ads, sem_util.adb (Is_Renaming_Declaration): Remove.
9246 2020-06-15 Ed Schonberg <schonberg@adacore.com>
9248 * freeze.adb (Freeze_Expression): When traversing the tree
9249 looking for the proper insertion point for the freeze node of an
9250 entity that is declared in an outer scope, set the candidate
9251 subprogram body node properly. Previous code has an off-by-one
9252 error.
9254 2020-06-15 Eric Botcazou <ebotcazou@adacore.com>
9256 * exp_attr.adb (Expand_N_Attribute_Reference) <Has_Same_Storage>:
9257 Do not do superfluous work. Add the condition (X'Size /= 0) on
9258 both paths and turn binary AND into short-circuit AND THEN.
9260 2020-06-15 Steve Baird <baird@adacore.com>
9262 * sem_attr.adb (Analyze_Attribute): In the Loop_Entry case,
9263 replace a call to Statically_Denotes_Object with a call to
9264 Statically_Names_Object and clean up the preceding comment.
9266 2020-06-15 Eric Botcazou <ebotcazou@adacore.com>
9268 * sem_res.adb (Resolve_Set_Membership): Remove local variable.
9269 In the non-overloaded case, call Intersect_Types on the left
9270 operand and the first alternative to get the resolution type.
9271 But test the subtype of the left operand to give the warning.
9273 2020-06-12 Steve Baird <baird@adacore.com>
9275 * sem_res.adb (Valid_Conversion): The simpler cases of
9276 violations of the aforementioned 8.6 rule are already handled
9277 correctly. These include cases where the operand of the type
9278 conversion is an access parameter or a stand-alone object of an
9279 anonymous access type. Add code to detect violations where the
9280 operand of the type conversion is an access discriminant whose
9281 accessibility level is tied to one of the other simpler cases.
9282 This is implemented in a new function,
9283 Valid_Conversion.Is_Discrim_Of_Bad_Access_Conversion_Argument,
9284 which is called in place of the previous test.
9286 2020-06-12 Bob Duff <duff@adacore.com>
9288 * exp_attr.adb (Put_Image): Remove assertion. This assertion is
9289 False in mixed-Ada-version programs.
9290 * exp_put_image.adb (Tagged_Put_Image_Enabled): New flag to make
9291 it easy to experiment with Put_Image on tagged types. False in
9292 this version.
9293 (Enable_Put_Image): Enable in pre-2020. Workarounds: Disable
9294 for tagged types if Tagged_Put_Image_Enabled is False. Disable
9295 for access-to-subprogram types. Disable if errors have been
9296 detected, or Sink is unavailable.
9297 (Preload_Sink): Move all conditionals here, from Sem_Ch10, so
9298 they can be nearby related code in Enable_Put_Image. Load Sink
9299 only if we have seen a tagged type. This removes the dilemma
9300 about calling Preload_Sink when compiling the compiler, which
9301 caused unwanted dependences.
9302 * exp_put_image.ads (Preload_Sink): New formal Compilation_Unit,
9303 needed to move all conditionals here, from Sem_Ch10.
9304 * libgnat/a-stouut.adb (Put_UTF_8): Make this suitable for
9305 inlining, so we don't get warnings about inlining in some tests.
9306 And so it can be inlined!
9307 * opt.ads (Tagged_Seen): New flag (see Preload_Sink).
9308 * scng.adb (Scan): Set new Tagged_Seen flag.
9309 * sem_ch10.adb (Analyze_Compilation_Unit): Move conditionals and
9310 comments regarding Preload_Sink into Preload_Sink.
9312 2020-06-12 Arnaud Charlet <charlet@adacore.com>
9314 * sem_res.adb (Resolve_Actuals): Check for AI12-0074.
9316 2020-06-12 Olivier Hainque <hainque@adacore.com>
9318 * libgnat/s-secsta.ads (Memory_Alignment): New constant, memory
9319 alignment for chunks and allocated blocks. Initialize to
9320 Standard'Maximum_Alignment * 2.
9321 (Chunk_Memory): Use it.
9322 * libgnat/s-secsta.adb (Round_Up): Likewise.
9324 2020-06-12 Piotr Trojanek <trojanek@adacore.com>
9326 * par-prag.adb: Fix ordering.
9327 * snames.ads-tmpl (Name_Test_Case, Pragma_Test_Case): Likewise.
9328 * sem_prag.adb (Sig_Flags): Likewise.
9330 2020-06-12 Arnaud Charlet <charlet@adacore.com>
9332 * sem_res.adb (Resolve_Entity_Name): Fix handling of expressions
9333 containing array attributes wrt Ada 83 detection.
9335 2020-06-12 Steve Baird <baird@adacore.com>
9337 * sem_util.ads, sem_util.adb: Define 3 new Boolean-valued
9338 functions - Statically_Denotes_Entity,
9339 Statically_Denotes_Object, and Statically_Names_Object. The
9340 first two were taken from sem_attr.adb. The term "statically
9341 names" is defined in the Ada RM and the new function
9342 Statically_Names_Object is intended to reflect that definition,
9343 or more precisely, as described in a comment in the code, to
9344 reflect the expected future definition of that term.
9345 * sem_attr.adb: Delete functions Statically_Denotes_Object and
9346 Statically_Denotes_Entity; these two functions have been moved
9347 to package Sem_Util. Replace call to Statically_Denotes_Object
9348 with a call to Statically_Names_Object as per AI12-0217 (a
9349 binding interpretation, so no Ada_Version check).
9350 * exp_ch9.adb (Expand_Entry_Barrier.Is_Simple_Barrier): Change
9351 name of function (it was previously Is_Simple_Barrier_Name)
9352 because the function should return True in the case of a static
9353 expression; implement this requirement. Change function to
9354 include a call to Statically_Names_Object so that, for Ada_2020
9355 and later, it will return True for appropriate subcomponent
9356 names.
9357 (Expand_Entry_Barrier.Is_Pure_Barrier): Handle
9358 N_Indexed_Component and N_Selected_Component cases by calling
9359 Statically_Names_Object.
9360 (Expand_Entry_Barrier): Reorganize to treat Simple_Barriers and
9361 Pure_Barriers more uniformly. Prevent cascaded errors.
9363 2020-06-12 Ed Schonberg <schonberg@adacore.com>
9365 * sem_ch12.adb (Find_Matching_Actual): Add guard on search loops
9366 to detect a compilation error when using a compiler built
9367 without assertions.
9368 (Instantiate_Formal_Subprogram): Create a new subprogram name
9369 for the actual only if formal has contract aspects and expansion
9370 is enabled.
9372 2020-06-12 Eric Botcazou <ebotcazou@adacore.com>
9374 * exp_aggr.adb: Add with and use clauses for Sem_Mech.
9375 (Get_Base_Object): New function to get the base object of a node.
9376 (In_Place_Assign_OK): Add Target_Object parameter. Deal with a
9377 qualified expression on entry. Remove short-circuit for array
9378 aggregates with a single "others" choice. Do not look into the
9379 components of the aggregate if the parent is an allocator.
9380 (Check_Component): Add T_OK parameter and rewrite.
9381 (Safe_Component): Invoke Check_Component with T_OK set to False.
9382 (Convert_To_Assignments): Try to use an in-place assignment for
9383 any target; for that, call Get_Base_Object on the target and pass
9384 the result to In_Place_Assign_OK.
9385 (Expand_Array_Aggregate): Use Parent_Kind and Parent_Node more
9386 consistently. For an assignment, call Get_Base_Object on the
9387 target and pass the result to In_Place_Assign_OK.
9389 2020-06-12 Dmitriy Anisimkov <anisimko@adacore.com>
9391 * socket.c (__gnat_minus_500ms): Use GetVersionEx to detect
9392 Windows Server version.
9393 * libgnat/g-sothco.ads (Minus_500ms_Windows_Timeout): Remade to
9394 Boolean constant.
9395 * libgnat/g-socket.adb (Set_Socket_Option): Use
9396 Minus_500ms_Windows_Timeout constant instead of function call.
9398 2020-06-12 Arnaud Charlet <charlet@adacore.com>
9400 * libgnat/a-coinho.ads, libgnat/a-coinho.adb,
9401 libgnat/a-coinho__shared.ads, libgnat/a-coinho__shared.adb
9402 (Swap): New procedure.
9404 2020-06-12 Arnaud Charlet <charlet@adacore.com>
9406 * exp_ch6.adb (Expand_N_Subprogram_Declaration): Do nothing for
9407 a subprogram declared in a protected body.
9408 * exp_ch9.ads, exp_ch9.adb
9409 (Build_Private_Protected_Declaration): Moved to sem_ch6.adb.
9410 (Expand_N_Protected_Body): Do nothing for a subprogram declared
9411 in a protected body.
9412 * sem_ch6.adb (Build_Internal_Protected_Declaration): Moved from
9413 exp_ch9.adb and renamed and fixed to ensure in particular that
9414 such subprograms have convention Intrinsic and have no protected
9415 version.
9416 (Analyze_Subprogram_Body_Helper): Call
9417 Build_Internal_Protected_Declaration.
9418 (Move_Pragmas): Moved up and merged with the more general
9419 version from Build_Private_Protected_Declaration. We only want
9420 to copy selected pragmas, most pragmas are not suitable for a
9421 copy on the spec.
9423 2020-06-12 Ed Schonberg <schonberg@adacore.com>
9425 * sem_ch6.adb (Check_Overriding_Indicatior): Reject an
9426 overriding indicator on a subprogram declared within a protected
9427 body.
9429 2020-06-12 Piotr Trojanek <trojanek@adacore.com>
9431 * contracts.adb, einfo.adb, sem_ch4.adb, sem_ch6.adb,

9442 * sem_ch13.adb (Analyze_Aspect_Specifications): Check
9443 13.1(9.2/5) for representation aspects.
9445 2020-06-12 Bob Duff <duff@adacore.com>
9447 * exp_put_image.ads, exp_put_image.adb (Preload_Sink): Procedure
9448 for preloading type Sink. This has the side effect of loading
9449 various dependents, including Ada.Strings.UTF_Encoding.
9450 (Enable_Put_Image): Disable Put_Image in pre-2020 versions of
9451 Ada. This limitation can probably be lifted later. Enable for
9452 tagged types except in predefined units. Disable for CPP types;
9453 Put_Image is legal, just prints the type name.
9454 * sem_attr.adb (Check_Put_Image_Attribute): Don't complain about
9455 Put_Image of CPP types; instead call the "unknown" version of
9456 Put_Image.
9457 * sem_ch10.adb (Analyze_Compilation_Unit): Call Preload_Sink.
9459 2020-06-12 Piotr Trojanek <trojanek@adacore.com>
9461 * sem_warn.adb (Warn_On_Overlapping_Actuals): Simplify.
9463 2020-06-12 Piotr Trojanek <trojanek@adacore.com>

9498 (Is_Non_Preelaborable_Construct.Visit): Recurse on the
9499 Explicit_Actual_Parameter field of N_Parameter_Association.
9500 (Is_Non_Preelaborable_Construct.Visit_Subexpression): In Ada 2020,
9501 for a call to a preelaborable function, visit the parameter list;
9502 otherwise, raise Non_Preelaborable exception.
9503 (Is_Preelaborable_Construct): Likewise, but recursively check the
9504 parameters instead and return false upon failure, otherwise true.
9505 * sinfo.ads (Is_Preelaborable_Call): New flag in call marker nodes.
9506 (Is_Preelaborable_Call): New inline function.
9507 (Set_Is_Preelaborable_Call): New inline procedure.
9508 * sinfo.adb (Is_Preelaborable_Call): New inline function.
9509 (Set_Is_Preelaborable_Call): New inline procedure.
9511 2020-06-12 Bob Duff <duff@adacore.com>

9515 2020-06-12 Eric Botcazou <ebotcazou@adacore.com>
9517 * sem_ch4.adb (Try_Container_Indexing): Replace call to
9518 First_Discriminant by Get_Reference_Discriminant to get the
9519 reference discriminant.
9520 * sem_ch13.adb (Check_Indexing_Functions): Likewise.
9521 * sem_ch5.adb (Preanalyze_Range): Call Get_Reference_Discriminant
9522 to get the reference discriminant.
9523 * sem_util.adb (Is_OK_Variable_For_Out_Formal): Treat all
9524 Ada 2012 implicit dereferences in only one place.
9525 (Is_Variable): Minor tweak.
9527 2020-06-12 Ed Schonberg <schonberg@adacore.com>
9529 * sem_ch12.adb (Has_Contracts): New predicate to check whether a
9530 formal subprogram carries an aspect specification for a pre- or
9531 postcondition.
9532 (Build_Subprogram_Wrappers): If actual is overloaded, create a
9533 new name to be used in call inside wrapper body. This names
9534 carries the interpretations of the actual, and is resolved when
9535 the body is analyzed.
9536 (Build_Subprogram_Body_Wrapper): Use this generated name in
9537 call.
9538 (Build_Subprogram_Decl_Wrapper): Build profile of wrapper from
9539 the profile of formal, and reset type entities for subsequent
9540 analysis.
9542 2020-06-12 Bob Duff <duff@adacore.com>
9544 * debug.adb: Remove usage of -gnatd_z.
9545 * exp_attr.adb, exp_put_image.ads, exp_put_image.adb: Clean up
9546 the enable/disable code. If Put_Image is disabled for a type,
9547 systematically call the "unknown" version. Improve comments.
9548 Consolidate workarounds. Remove usage of -gnatd_z.
9550 2020-06-12 Eric Botcazou <ebotcazou@adacore.com>

9564 specification. Add pragmas Ada_2020.
9565 * libgnat/a-stouut.ads, libgnat/a-stteou.ads: Add Preelaborate,
9566 because the Big_Numbers packages have Preelaborate, and now
9567 depend on these Text_Output packages.

9580 prescribed by AI12-0269 for simple return statements of
9581 No_Return functions, and also checks extended statements.
9582 (Analyze_Return_Statement): Only give an error on a return
9583 statement in No_Return procedures. Use idiomatic form.
9584 * sem_ch8.adb (Analyze_Subprogram_Renaming): Adjust error
9585 message for No_Return renaming subprogram.
9586 * sem_prag.adb (Analyze_Pragma) <Pragma_No_Return>: Accept
9587 it on functions and generic functions in Ada 2020.
9589 2020-06-11 Eric Botcazou <ebotcazou@adacore.com>
9591 * sem_res.adb (Resolve_Implicit_Dereference): In an instance,
9592 reset the type of the prefix if it is private before building
9593 the dereference.
9595 2020-06-11 Eric Botcazou <ebotcazou@adacore.com>

9603 anymore. Invalid_Big_Integer is not used.
9604 Greatest_Common_Divisor returns Big_Positive.
9606 2020-06-11 Piotr Trojanek <trojanek@adacore.com>
9608 * sem_aggr.adb (Get_Value): Refine type of the Compon parameter.

9624 * exp_pakd.ads: Add paragraph about scalar storage order.
9625 * exp_pakd.adb (Install_PAT): Do not set the scalar storage

9628 (Create_Packed_Array_Impl_Type): ...here as well.
9629 * rtsfind.ads (RE_Id): Add RE_Rev_Packed_Bytes{1,2,4}.

9638 references to SPARK RM 7.1.3 rule numbers.
9640 2020-06-11 Ed Schonberg <schonberg@adacore.com>
9642 * sem_warn.adb (Warn_On_Overlapping_Actuals): Simplify code,
9643 remove inner predicate Is_Covered_Formal, preserve warning for
9644 two overlapping composite types when only one is writable, and
9645 for two overlapping and writable elementary types.
9647 2020-06-11 Steve Baird <baird@adacore.com>
9649 * contracts.adb (Add_Contract_Item): Support specifying
9650 volatility refinement aspects for types.

9656 which performs the work that needs to be done for both object
9657 declarations and types.
9658 (Analyze_Object_Contract): Add a call to
9659 Check_Type_Or_Object_External_Properties and remove the code in
9660 this procedure which did much of the work that is now performed
9661 by that call.
9662 (Analyze_Type_Contract): Implement this new routine as nothing
9663 more than a call to Check_Type_Or_Object_External_Properties.
9664 * contracts.ads: Update comment for Add_Contract_To_Item because
9665 types can have contracts. Follow (questionable) precedent and
9666 declare new routine Analyze_Type_Contract as visible (following
9667 example of Analyze_Object_Contract), despite the fact that it is
9668 never called from outside of the package where it is declared.
9669 * einfo.adb (Contract, Set_Contract): Id argument can be a type;
9670 support this case.
9671 (Write_Field34_Name): Field name is "contract" for a type.
9672 * einfo.ads: Update comment describing Contract attribute.
9673 * sem_ch3.adb (Build_Derived_Numeric_Type): Is_Volatile should
9674 return same answer for all subtypes of a given type. Thus, when
9675 building the base type for something like type Volatile_1_To_10
9676 is range 1 .. 10 with Volatile; that basetype should be marked
9677 as being volatile.
9678 (Access_Type_Declaration): Add SPARK-specific legality check
9679 that the designated type of an access type shall be compatible
9680 with respect to volatility with the access type.
9681 * sem_ch12.adb (Check_Shared_Variable_Control_Aspects): Add
9682 SPARK-specific legality check that an actual type parameter in
9683 an instantiation shall be compatible with respect to volatility
9684 with the corresponding formal type.
9685 * sem_ch13.adb (Analyze_Aspect_Specifications): Perform checks
9686 for aspect specs for the 4 volatility refinement aspects that
9687 were already being performed for all language-defined aspects.
9688 * sem_prag.adb (Analyze_External_Property_In_Decl_Part,
9689 Analyze_Pragma): External properties (other than No_Caching) may
9690 be specified for a type, including a generic formal type.
9691 * sem_util.ads: Declare new subprograms - Async_Readers_Enabled,
9692 Async_Writers_Enabled, Effective_Reads, Effective_Writes, and
9693 Check_Volatility_Compatibility.
9694 * sem_util.adb (Async_Readers_Enabled, Async_Writers_Enabled,
9695 Effective_Reads, Effective_Writes): Initial implementation of
9696 new functions for querying aspect values.
9697 (Check_Volatility_Compatibility): New procedure intended for use
9698 in checking all SPARK legality rules of the form "<> shall be
9699 compatible with respect to volatility with <>".
9700 (Has_Enabled_Property): Update comment because Item_Id can be a
9701 type. Change name of nested Variable_Has_Enabled_Property
9702 function to Type_Or_Variable_Has_Enabled_Property; add a
9703 parameter to that function because recursion may be needed,
9704 e.g., in the case of a derived typ). Cope with the case where
9705 the argument to Has_Enabled_Property is a type.
9707 2020-06-11 Piotr Trojanek <trojanek@adacore.com>
9709 * sem_aggr.adb (Add_Association): Add assertion about the formal
9710 parameters.
9711 (Propagate_Discriminants): Always add an explicit component
9712 association, so that an "others => <>" association is never
9713 needed.

9717 * exp_put_image.adb (Build_Elementary_Put_Image_Call): If the
9718 underlying type is real, call Put_Image_Unknown.
9719 (Build_Unknown_Put_Image_Call): Pass the type name to
9720 Put_Image_Unknown.
9721 * libgnat/s-putima.ads, libgnat/s-putima.adb
9722 (Put_Image_Unknown): Add Type_Name parameter. Remove
9723 overly-detailed documentation of what it does; better to leave
9724 it open.
9726 2020-06-11 Piotr Trojanek <trojanek@adacore.com>
9728 * sem_ch3.adb (Build_Constrained_Array_Type,

9735 * sem_ch3.adb (Build_Subtype, Inherit_Predicate_Flags): Move...
9736 * sem_util.adb (Build_Subtype): Here. Add parameters for
9737 references to objects previously declared in enclosing scopes.

9739 Build_Subtype.
9740 * sem_util.ads (Build_Overriding_Spec): Reorder alphabetically.
9741 (Build_Subtype): Moved from Sem_Ch3; comments updated.
9742 (Build_Constrained_Itype): Moved from Sem_Aggr; comments

9748 Pos.
9750 2020-06-11 Piotr Trojanek <trojanek@adacore.com>
9752 * sem_aggr.adb (Build_Constrained_Itype): Previously a declare
9753 block, now a separate procedure; the only change is that now
9754 New_Assoc_List might include components and an others clause,
9755 which we ignore (while we deal with discriminants exactly as we
9756 did before); extend a ??? comment about how this routine is
9757 different from the Build_Subtype
9758 (Resolve_Record_Aggregate): Create a constrained itype not just
9759 for the outermost record aggregate, but for its inner record
9760 aggregates as well.

9799 (Analyze_Renamed_Entry): Deal with implicit dereferences.
9800 (Find_Selected_Component): Do not insert an explicit dereference
9801 here. Call Implicitly_Designated_Type to get the designated type
9802 for an implicit dereference. Call Has_Components, Is_Task_Type
9803 and Is_Protected_Type directly. Adjust test for error.
9804 * sem_res.adb (Resolve_Implicit_Dereference): New procedure.
9805 (Resolve_Call): Call Resolve_Indexed_Component last.
9806 (Resolve_Entry): Call Resolve_Implicit_Dereference on the prefix.
9807 (Resolve_Indexed_Component): Call Implicitly_Designated_Type to
9808 get the designated type for an implicit dereference and
9809 Resolve_Implicit_Dereference on the prefix at the end.
9810 (Resolve_Selected_Component): Likewise.
9811 (Resolve_Slice): Likewise. Do not apply access checks here.
9812 * sem_util.ads (Implicitly_Designated_Type): Declare.
9813 * sem_util.adb (Copy_And_Maybe_Dereference): Simplify.
9814 (Implicitly_Designated_Type): New function.
9815 (Object_Access_Level): Fix typo.
9816 * sem_warn.adb (Check_Unset_Reference): Test Comes_From_Source
9817 on the original node.
9819 2020-06-11 Piotr Trojanek <trojanek@adacore.com>

9822 * exp_aggr.adb (Is_Static_Dispatch_Table_Aggregate): Recognize
9823 aggregates of the Ada.Tags.Object_Specific_Data type as static.
9824 * sem_aggr.adb (Check_Static_Discriminated_Subtype): Deconstruct
9825 and do not call it from Build_Constrained_Itype.
9827 2020-06-11 Piotr Trojanek <trojanek@adacore.com>
9829 * exp_disp.adb (Make_Secondary_DT): Internally generated OSD
9830 tables are now constant.
9832 2020-06-11 Piotr Trojanek <trojanek@adacore.com>
9834 * exp_aggr.adb (Backend_Processing_Possible): Remove useless
9835 call.

9845 Root_Subpool): Mark with Preelaborable_Initialization.
9847 2020-06-11 Javier Miranda <miranda@adacore.com>

9853 New routines.
9854 * sem_util.adb (New_Copy_Separate_List, New_Copy_Separate_Tree):
9855 New routines.
9856 (New_Copy_Tree): Extend the machinery that detects syntactic
9857 nodes to handle lists of indentifiers with field More_Ids;
9858 otherwise such nodes are erroneously handled as semantic nodes.
9859 Copy aspect specifications attached to nodes.
9860 * sem_ch12.adb (Copy_Generic_Node): Protect reading attribute
9861 Etype.
9863 2020-06-11 Bob Duff <duff@adacore.com>
9865 * sem_ch13.adb (Analyze_Aspect_Specifications): Do not set the
9866 Has_Predicates flag when the Predicate_Failure aspect is seen.
9867 It is legal (but pointless) to use this aspect without a
9868 predicate. If we set the flag, we generate a half-baked
9869 Predicate procedure, and if that procedure is nested, it causes
9870 unnesting to crash.
9872 2020-06-11 Bob Duff <duff@adacore.com>
9874 * exp_put_image.adb (Build_Record_Put_Image_Procedure): Remove
9875 special processing of protected types, because those are handled
9876 by Build_Protected_Put_Image_Call.
9877 (Enable_Put_Image): Use the switch -gnatd_z to control enabling
9878 of Put_Image. Disable Put_Image for types in Remote_Types
9879 packages.

9893 2020-06-11 Justin Squirek <squirek@adacore.com>
9895 * sem_util.adb (Expand_N_Attribute_Reference): Use original
9896 nodes where required to avoid looking at the expanded tree.

9915 * libgnat/s-aomoar.ads, libgnat/s-aomoar.adb: New files.

9918 * libgnat/s-atopar.adb: Move...
9919 * libgnat/s-aoinar.adb: Here.
9920 * impunit.adb: Update list of runtime files.
9921 * Makefile.rtl (GNATRTL_NONTASKING_OBJS=): Adjust.
9923 2020-06-10 Arnaud Charlet <charlet@adacore.com>
9925 * snames.ads-tmpl (Name_Characters_Assertion_Check,

9949 the parent node of the original tree when dereferencing.
9951 2020-06-10 Ed Schonberg <schonberg@adacore.com>
9953 * sem_warn.adb (Warn_On_Overlapping_Actuals): Add a warning when
9954 two actuals in a call overlap, both are composite types that may
9955 be passed by reference, and only one of them is writable.
9957 2020-06-10 Eric Botcazou <ebotcazou@adacore.com>
9959 * exp_ch4.adb (Expand_N_In): Use an expression with actions to

9974 2020-06-10 Bob Duff <duff@adacore.com>
9976 * sem_prag.adb (Invariant): Remove the pragma removing code. It
9977 doesn't work to remove the pragma, because various flags are set
9978 during Build_Invariant_Procedure_Declaration and
9979 Build_Invariant_Procedure_Body that need to be set to avoid the
9980 spurious warnings.
9981 * exp_util.adb (Make_Invariant_Call): Avoid calling the
9982 invariant-checking procedure if the body is empty. This is an
9983 optimization.
9985 2020-06-10 Vasiliy Fofanov <fofanov@adacore.com>
9987 * doc/gnat_ugn/gnat_utility_programs.rst: Fix gnatmetric

9998 false for a type with discriminants.
9999 (Convert_To_Assignments): Use Parent_Node and Parent_Kind more
10000 consistently. In the in-place assignment case, first apply a
10001 discriminant check if need be, and be prepared for a rewritten
10002 aggregate as a result.
10004 2020-06-10 Arnaud Charlet <charlet@adacore.com>

10029 for Enum_Rep attribute.
10030 * exp_spark.adb (Expand_SPARK_N_Attribute_Reference): Remove
10031 duplicated code for folding Enum_Rep attribute.
10032 * sem_attr.adb (Eval_Attribute): Relax condition for folding
10033 Enum_Rep attribute; previously dead code is now executed when
10034 the attribute prefix is an enumeration literal; refine type in
10035 processing of Enum_Val.
10037 2020-06-10 Javier Miranda <miranda@adacore.com>
10039 * sem_ch3.adb (Analyze_Declarations): Adjust the machinery that
10040 takes care of late body overriding of initialize, adjust,
10041 finalize. Remove ASIS mode code.

10051 call to the corresponding Access_ ubprogram_Wrapper. Handle
10052 derived types that inherit contract from parent.
10053 * sem_prag.adb (Build_Access_Subprogram_Wrapper): Build
10054 subprogram declaration for subprogram that incorporates the
10055 contracts of an Access_To_Subprogram type declaration. Build
10056 corresponding body and attach it to freeze actions for type.

10125 subtype conformance of overriding dispatching primitive.
10126 * sem_eval.adb (Subtypes_Statically_Match): Handle derivations
10127 of private subtypes.
10128 * libgnat/g-exptty.adb, libgnat/g-exptty.ads
10129 (Set_Up_Communications): Fix the profile since null-exclusion is

10297 (Complete_Private_Subtype): Call Propagate_Predicate_Attributes.
10298 (Process_Full_View): Do not deal with base types explicitly for

10325 to reflect the order of adding edges. Clarify comments.
10326 * bindo-graphs.adb (Add_Edge_Kind_Check): Correct the
10327 assertions. Reorder the "when"s to match the order of adding
10328 edges, and therefore the order of enumerals in type
10329 Library_Graph_Edge_Kind. Change names to "Old_" and "New_" to
10330 clarify what's what. Combine Invocation_Edge into the "<="
10331 test. Fix the "raise Program_Error" message, which was
10332 backwards.
10334 2020-06-09 Bob Duff <duff@adacore.com>

10371 * exp_ch9.adb (Build_Master_Renaming): Make name in renaming
10372 declaration unique by adding a numeric suffix, to prevent
10373 accidental name conflict when several instantiations of a
10374 package containing an access_to_incomplete type that designate
10375 tasks appear in the same scope.
10377 2020-06-09 Piotr Trojanek <trojanek@adacore.com>

10386 Eval_Type_Conversion): Relax rules on relational operators and
10387 type conversions of static string types.
10389 2020-06-09 Arnaud Charlet <charlet@adacore.com>
10391 * sem_util.ads, sem_util.adb (Is_Partially_Initialized_Type):
10392 Take Default_Value and Default_Component_Value into account.
10393 * sem_ch3.adb (Analyze_Object_Declaration): Update comment.
10395 2020-06-09 Bob Duff <duff@adacore.com>

10400 2020-06-08 Steve Baird <baird@adacore.com>
10402 * sem_prag.adb (Analyze_Pragma.Set_Ravenscar_Profile): Add
10403 appropriate call to Set_Restriction_No_Dependence if Ada_Version
10404 >= Ada2012 and Profile is either Ravenscar or a GNAT-defined
10405 Ravenscar variant (i.e., not Jorvik).
10407 2020-06-08 Arnaud Charlet <charlet@adacore.com>
10409 * sem_ch5.adb: Fix typo.
10410 * sem_ch8.adb (Analyze_Renamed_Primitive_Operation): Check that

10428 2020-06-08 Piotr Trojanek <trojanek@adacore.com>
10430 * exp_spark.adb (Expand_SPARK_N_Attribute_Reference): Port
10431 changes in frontend expander.
10433 2020-06-08 Piotr Trojanek <trojanek@adacore.com>

10442 Profile_Info.
10443 * targparm.adb (Get_Target_Parameters): Handle "pragma Profile
10444 (Jorvik);" similarly to "pragma Profile (Ravenscar);".
10445 * snames.ads-tmpl: Declare Name_Jorvik Name_Id. Unlike
10446 Ravenscar, Jorvik is not a pragma name and has no corresponding
10447 element in the Pragma_Id enumeration type; this means that its
10448 declaration must not occur between those of First_Pragma_Name
10449 and Last_Pragma_Name.
10450 * sem_prag.adb (Analyze_Pragma): Add call to
10451 Set_Ravenscar_Profile for Jorvik, similar to the existing calls
10452 for Ravenscar and the GNAT Ravenscar variants.

10456 * sem_ch8.adb (Analyze_Object_Renaming): Update Get_Object_Name
10457 to go through N_Qualified_Expression and N_Type_Conversion. Fix
10458 another case of wrong usage of E_Anonymous_Access_Type instead
10459 of Anonymous_Access_Kind.
10460 * sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): Work
10461 on the original node.
10462 (Is_Aliased_View): Take into account N_Qualified_Expression.
10464 2020-06-08 Arnaud Charlet <charlet@adacore.com>
10466 * sem_eval.adb (Eval_Type_Conversion): Fix handling of
10467 enumeration to integer conversions.
10468 * exp_attr.adb (Expand_N_Attribute_Reference
10469 [Attribute_Enum_Rep]): Remove special casing for first-level
10470 renaming, best left to the general folding mechanism via
10471 Eval_Type_Conversion.
10473 2020-06-08 Eric Botcazou <ebotcazou@adacore.com>
10475 * atree.adb (New_Copy): Do not clear Has_Dynamic_Range_Check.
10476 * checks.ads (Append_Range_Checks): Remove Flag_Node parameter.
10477 (Insert_Range_Checks): Likewise and remove default value of

10479 * checks.adb (Append_Range_Checks): Remove Flag_Node parameter.
10480 Do not test and set Has_Dynamic_Range_Check.
10481 (Insert_Range_Checks): Likewise and remove default value of
10482 Static_Loc parameter.
10483 * csinfo.adb (CSinfo): Remove 'L' from [NEUB]_Fields pattern and
10484 do not handle Has_Dynamic_Range_Check.
10485 * exp_ch5.adb (Expand_N_Assignment_Statement): Remove argument
10486 in call to Insert_Range_Checks.
10487 * sem_ch3.adb (Analyze_Subtype_Declaration): Do not fiddle
10488 with Has_Dynamic_Range_Check.
10489 (Process_Range_Expr_In_Decl): Remove argument in calls to
10490 Insert_Range_Checks and Append_Range_Checks.
10491 * sinfo.ads (Has_Dynamic_Range_Check): Delete.
10492 (Set_Has_Dynamic_Range_Check): Likewise.
10493 * sinfo.adb (Has_Dynamic_Range_Check): Delete.
10494 (Set_Has_Dynamic_Range_Check): Likewise.
10495 * treepr.adb (Print_Node): Do not print Has_Dynamic_Range_Check.
10497 2020-06-08 Steve Baird <baird@adacore.com>
10499 * sem_ch13.ads: Export new function
10500 All_Membership_Choices_Static.
10501 * sem_ch13.adb: Implement new function
10502 All_Membership_Choices_Static. This involves moving the
10503 functions Is_Static_Choice and All_Membership_Choices_Static,
10504 which were previously declared within the function
10505 Is_Predicate_Static, out to library level so that they can be
10506 called by the new function. The already-exisiting code in
10507 Is_Predicate_Static which became the body of
10508 All_Membership_Choices_Static is replaced with a call to the new
10509 function in order to avoid duplication.
10510 * exp_ch9.adb (Is_Pure_Barrier): Several changes needed to
10511 implement rules of AI12-0290 and RM D.7's definition of
10512 "pure-barrier-eligible". These changes include adding a call to
10513 the new function Sem_13.All_Membership_Choices_Static, as per
10514 the "see 4.9" in RM D.7(1.6/5).
10516 2020-06-08 Richard Kenner <kenner@adacore.com>
10518 * exp_unst.adb (Visit_Node): When visiting array attribute
10519 nodes, in addition to checking the type of Get_Referenced_Object
10520 of the prefix, also check the actual type of the prefix.
10522 2020-06-08 Gary Dismukes <dismukes@adacore.com>
10524 * checks.adb (Apply_Predicate_Check): Refine test for being in a
10525 subprogram body to account for no Corresponding_Body case,
10526 avoiding blowups arising due to other changes here.
10527 * exp_ch4.adb (Expand_N_Qualified_Expression): Apply predicate
10528 checks, if any, after constraint checks are applied.
10529 * sem_eval.ads (Check_Expression_Against_Static_Predicate): Add
10530 Check_Failure_Is_Error formal for conditionalizing warning vs.
10531 error messages.
10532 * sem_eval.adb (Check_Expression_Against_Static_Predicate):
10533 Issue an error message rather than a warning when the new
10534 Check_Failure_Is_Error formal is True. In the nonstatic or
10535 Dynamic_Predicate case where the predicate is known to fail,
10536 emit the check to ensure that folded cases get checks applied.
10537 * sem_res.adb (Resolve_Qualified_Expression): Call
10538 Check_Expression_Against_Static_Predicate, passing True for
10539 Check_Failure_Is_Error, to ensure we reject static predicate
10540 violations. Remove code that was conditionally calling
10541 Apply_Predicate_Check, which is no longer needed, and that check
10542 procedure shouldn't be called from a resolution routine in any
10543 case. Also remove associated comment about preventing infinite
10544 recursion and consistency with Resolve_Type_Conversion, since
10545 that handling was already similarly removed from
10546 Resolve_Type_Convesion at some point.
10547 (Resolve_Type_Conversion): Add passing of True for
10548 Check_Failure_Is_Error parameter on call to
10549 Check_Expression_Against_Static_Predicate, to ensure that static
10550 conversion cases that violate a predicate are rejected as
10551 errors.
10553 2020-06-08 Piotr Trojanek <trojanek@adacore.com>
10555 * snames.ads-tmpl (Name_SPARK): Restore after being deleted.

10567 Remove processing of SPARK_05 restriction.
10568 * gnat_rm.texi: Regenerate.
10569 * opt.ads: Remove processing of old checksum which is now
10570 handled by gprbuild directly.
10572 2020-06-08 Arnaud Charlet <charlet@adacore.com>
10574 * sem_ch12.adb (Instantiate_Object): Relax rules related to null
10575 exclusions and generic objects. Handle all anonymous types
10576 consistently and not just E_Anonymous_Access_Type.
10577 * sem_ch8.adb (Analyze_Object_Renaming): Change wording so that
10578 it applies to both renamings and instantiations to avoid
10579 confusion.
10581 2020-06-08 Arnaud Charlet <charlet@adacore.com>
10583 * libgnat/a-textio.ads (File_Mode): Fix typo in comment.
10585 2020-06-08 Eric Botcazou <ebotcazou@adacore.com>
10587 * sem_res.adb (Resolve_Indexed_Component): Do not give a warning
10588 for a nonatomic component of an atomic array which is subject to
10589 an address clause in Ada 2020 mode.
10590 (Resolve_Selected_Component): Likewise for an atomic record.
10592 2020-06-08 Philippe Gil <gil@adacore.com>
10594 * doc/gnat_ugn/the_gnat_compilation_model.rst: in "Handling
10595 Files with Multiple Units" part documents gnatname use for
10596 unmodified files handling and gnatchop use for files
10597 refactoring.
10598 * gnat_ugn.texi: Regenerate.
10600 2020-06-08 Arnaud Charlet <charlet@adacore.com>
10602 * doc/gnat_rm/implementation_defined_attributes.rst:
10603 Enum_Rep/Enum_Val are standard Ada 202x attributes.
10604 * gnat_rm.texi: Regenerate.
10606 2020-06-08 Javier Miranda <miranda@adacore.com>
10608 * exp_aggr.adb (Safe_Component): Remove code that considers as
10609 unsafe components that are aggregates; such removal allows the
10610 frontend to proceed and evaluate if they are safe by means of
10611 invoking Safe_Aggregate.
10613 2020-06-08 Piotr Trojanek <trojanek@adacore.com>
10615 * exp_spark.adb (Expand_SPARK_N_Attribute_Reference): Apply
10616 standard expansion to attributes First and Last.
10618 2020-06-08 Piotr Trojanek <trojanek@adacore.com>

10624 duplicated code with a call to Get_Index_Subtype.
10626 2020-06-08 Arnaud Charlet <charlet@adacore.com>
10628 * sem_ch8.adb (Analyze_Object_Renaming): Simplify code by moving
10629 many special cases to Is_Object_Reference and removing others by
10630 only checking renamings coming from sources.
10631 * sem_util.adb (Is_Object_Reference): Update for AI12-0226 and
10632 add more regular handling of 'Priority. Remove special cases no
10633 longer needed now that we are only checking renamings coming
10634 from sources.
10636 2020-06-08 Claire Dross <dross@adacore.com>
10638 * libgnat/a-cofove.adb (Insert_Space): The computation of Index
10639 generates a spurious compiler warning about a value not being in
10640 range for a statically dead branch. Silence it using pragma
10641 Warnings.
10643 2020-06-08 Bob Duff <duff@adacore.com>
10645 * bindo-graphs.adb (function Add_Edge): Rename
10646 Add_Edge_With_Return to Add_Edge; we can tell it returns because
10647 it's a function, and overloading seems appropriate in this case.
10648 If Activates_Task=True, and we're not going to add a new edge
10649 because an existing Pred-->Succ edge already exists, then set
10650 Activates_Task to True on the preexisting edge. This ensures
10651 that the message:
10652 info: use pragma Restrictions (No_Entry_Calls_In_Elaboration_Code)
10653 appears when appropriate, no matter in what order the edges
10654 happened to be processed.
10655 (procedure Add_Edge): Remove redundant assertions.
10656 (Activates_Task): Other kinds of edges can have
10657 Activates_Task=True. For example, if we had a With_Edge and
10658 then an Invocation_Edge with Activates_Task=True, then the
10659 With_Edge has Activates_Task set to True.
10660 (Add_Edge_Kind_Check): New procedure to prevent other bugs of
10661 this nature. For example, if we were to sometimes call Add_Edge
10662 for a Spec_Before_Body_Edge followed by Add_Edge for a
10663 With_Edge, and sometimes in the other order, that would cause a
10664 similar bug to what we're fixing here.
10665 (Set_Is_Recorded_Edge): Val parameter is not used. Get rid of
10666 it.
10667 (Set_Activates_Task): New procedure to set the Activates_Task flag.
10668 * bindo-graphs.ads (Library_Graph_Edge_Kind): Reorder the
10669 enumeration literals to facilitate Add_Edge_Kind_Check.
10670 * ali.adb (Known_ALI_Lines): The comment about "still available"
10671 was wrong. Fix that by erasing the comment, and encoding the
10672 relevant information in real code. Take advantage of Ada's full
10673 coverage rules by removing "others =>". Also DRY.
10675 2020-06-08 Ed Schonberg <schonberg@adacore.com>
10677 * par-ch12.adb (P_Formal_Derived_Type_Definition): Handle
10678 properly formal derived types that include aspect
10679 specifications, so that the "with" keyword appears twice in the
10680 formal type declaration.
10681 * sem_ch13.adb (Has_Generic_Parent): Return true if the type
10682 itself is a generic formal.
10684 2020-06-08 Dmitriy Anisimkov <anisimko@adacore.com>
10686 * socket.c (__gnat_minus_500ms): Remove
10687 IsWindowsVersionOrGreater from condition.
10689 2020-06-08 Claire Dross <dross@adacore.com>

10692 libgnat/a-cfhase.ads, libgnat/a-cforma.ads, libgnat/a-cforse.ads
10693 (Delete): Add Depends contract.
10695 2020-06-08 Arnaud Charlet <charlet@adacore.com>
10697 * snames.ads-tmpl (Name_Program_Error_Check,
10698 Name_Tasking_Check): New constants.
10699 * types.ads (Program_Error_Check, Tasking_Check): New constants.
10700 (All_Checks): Update accordingly.
10702 2020-06-05 Arnaud Charlet <charlet@adacore.com>
10704 * sem_prag.adb (Validate_Compile_Time_Warning_Or_Error): Use ??.
10706 2020-06-05 Arnaud Charlet <charlet@adacore.com>
10708 * cstand.adb (Create_Standard): Update comments.
10710 2020-06-05 Arnaud Charlet <charlet@adacore.com>
10712 * scng.adb (Scan): Fix typo to take into account all future
10713 versions of Ada.
10714 * sem_attr.ads (Attribute_Impl_Def): Add Attribute_Reduce for
10715 now.
10716 * sem_attr.adb (Analyze_Attribute): Only allow 'Reduce under
10717 -gnatX.
10718 * snames.ads-tmpl (Name_Reduce): Update comment.
10720 2020-06-05 Thomas Quinot <quinot@adacore.com>
10722 * exp_disp.adb (Expand_Interface_Thunk): Add comment about
10723 gnatcov reliance on specific name used for thunks.
10725 2020-06-05 Ed Schonberg <schonberg@adacore.com>
10727 * sem_ch3.adb (Analyze_Subtype_Declaration): For scalar types,
10728 and for subtype declarations without a constraint, subtype
10729 inherits Atomic flag from base type.
10731 2020-06-05 Piotr Trojanek <trojanek@adacore.com>
10733 * doc/gnat_rm/implementation_defined_attributes.rst (Enum_Rep):
10734 Remove extra colon.
10735 * gnat_rm.texi: Regenerate.
10737 2020-06-05 Eric Botcazou <ebotcazou@adacore.com>
10739 * atree.adb (New_Copy): Clear Has_Dynamic_Range_Check on
10740 subexpression nodes.
10741 * checks.adb (Append_Range_Checks): Assert that the node
10742 doesn't have the Has_Dynamic_Range_Check flag set.
10743 (Insert_Range_Checks): Likewise.
10744 * exp_ch3.adb (Expand_N_Subtype_Indication): Do not apply
10745 range checks for a full type or object declaration.
10746 * sem_ch3.ads: Move with and use clauses for Nlists to...
10747 (Process_Range_Expr_In_Decl): Change default to No_List for
10748 the Check_List parameter.
10749 * sem_ch3.adb: ...here.
10750 (Process_Range_Expr_In_Decl): Likewise. When the insertion
10751 node is a declaration, only insert on the list if is present
10752 when the declaration involves discriminants, and only insert
10753 on the node when there is no list otherwise.
10755 2020-06-05 Piotr Trojanek <trojanek@adacore.com>
10757 * sem_aggr.adb (Resolve_Record_Aggregate): Create the
10758 N_Aggregate node with its Expressions field set to No_List and
10759 not to an empty list.
10761 2020-06-05 Dmitriy Anisimkov <anisimko@adacore.com>
10763 * libgnat/s-os_lib.adb (Is_Dirsep): Moved from Build_Path to
10764 package level to reuse.
10765 (Normalize_Pathname.Final_Value): Reduce 2 'if' statements to
10766 one.
10767 (Normalize_Pathname.Fill_Directory): New procedure instead of
10768 function Get_Directory. Remove slash to backslash conversion and
10769 drive letter uppercasing on Windows.
10771 2020-06-05 Arnaud Charlet <charlet@adacore.com>
10773 * sem.adb (Assert_Done): Relax check for main unit, as it was
10774 overzealous in the case of the main unit itself.
10776 2020-06-05 Piotr Trojanek <trojanek@adacore.com>
10778 * exp_ch3.adb, sem_ch8.adb, sem_util.adb: Use Is_Incomplete_Type
10779 to make the code easier to read.
10781 2020-06-05 Piotr Trojanek <trojanek@adacore.com>
10783 * einfo.adb: Minor reformatting.
10784 * sem_util.adb (Has_Full_Default_Initialization,
10785 Is_Partially_Initialized_Type, Caller_Known_Size_Record,
10786 Large_Max_Size_Mutable): Iterate with
10787 First_Component/Next_Component; rename Ent to Comp.
10789 2020-06-05 Eric Botcazou <ebotcazou@adacore.com>
10791 * exp_aggr.adb (Aggr_Assignment_OK_For_Backend): Use
10792 Expr_Rep_Value instead of Expr_Value to obtain the equivalent
10793 integer value.
10794 * sem_eval.ads (Expr_Value): Document more supported cases.
10795 * sem_eval.adb (Expr_Rep_Value): Copy missing cases from
10796 Exp_Value.
10798 2020-06-05 Bob Duff <duff@adacore.com>
10800 * rtsfind.adb, rtsfind.ads: Move subtypes of RTU_Id into package
10801 body, because they are not needed by clients. Change "Child_" to
10802 "Descendant", because grandchildren and great grandchildren are
10803 involved. Replace all the repetitive comments with a single
10804 concise one. Change the parent subtypes to be more consistent;
10805 use the most specific parent.
10807 2020-06-05 Piotr Trojanek <trojanek@adacore.com>
10809 * rtsfind.ads, rtsfind.adb (Is_Text_IO_Special_Package): Moved

10819 * sem_ch9.adb, (Analyze_Task_Body): After analying the task
10820 body, indicate that all local variables have no delayed aspects.
10821 This prevents improper later calls to
10822 Check_Aspect_At_End_Of_Declarations, that would happen when the
10823 constructed task_procedure body (generated during expansion) is
10824 analyzed. The legality of aspect specifications that may appear
10825 on local declarations has already been established, and it is in
10826 general not possible to recheck them properly during expansion,
10827 when visibility may not be fully established.
10829 2020-06-05 Piotr Trojanek <trojanek@adacore.com>
10831 * libgnat/a-cofuve.ads (First): Add Global contract.

10844 2020-06-05 Eric Botcazou <ebotcazou@adacore.com>
10846 * sem_ch3.adb (Available_Full_View): New function returning
10847 either the full or the underlying full view.
10848 (Build_Full_Derivation): Add guard for the full view.
10849 (Copy_And_Build): Retrieve the underlying full view, if any,
10850 also if deriving a completion.
10851 (Build_Derived_Private_Type): Use Available_Full_View throughout
10852 to decide whether a full derivation must be done.

10876 * libgnat/s-stopoo.ads: Mark package Pure and leave room for
10877 Nonblocking once this aspect is supported.
10879 2020-06-05 Eric Botcazou <ebotcazou@adacore.com>
10881 * exp_attr.adb (Expand_N_Attribute_Reference) <Valid_Scalars>:
10882 Set the No_Truncation flag on the unchecked conversion built for
10883 scalar types.
10885 2020-06-05 Bob Duff <duff@adacore.com>
10887 * einfo.adb, einfo.ads, exp_util.adb: Remove Invariants_Ignored
10888 flag.
10889 * sem_prag.adb (Invariant): Instead of setting a flag to be
10890 checked elsewhere, remove the pragma as soon as it is analyzed
10891 and checked for legality.

10895 * checks.ads (Apply_Length_Check): Rename Ck_Node parameter to

10902 (Guard_Access): Likewise.
10903 (Selected_Length_Checks): Likewise. Also avoid shadowing in
10904 child procedures.
10905 (Selected_Range_Checks): Likewise.
10907 2020-06-05 Arnaud Charlet <charlet@adacore.com>
10909 * par-ch3.adb, par-ch4.adb, scng.adb, sem_aggr.adb,
10910 sem_ch10.adb, sem_ch12.adb, sem_prag.adb: Update wording: change
10911 Ada_2020 to Ada 2020 in comments and mention -gnat2020 instead
10912 of -gnatX switch.
10914 2020-06-04 Arnaud Charlet <charlet@adacore.com>
10916 * libgnat/i-c.ads (long_long, unsigned_long_long): New

10930 * sem_ch12.adb (Build_Suprogram_Body_Wrapper,
10931 Build_Subprogram_Decl_Wrapper): New suprograms, to create the
10932 wrappers needed to implement contracts on formsl subprograms at
10933 the point of instantiation.
10934 (Build_Subprogram_Wrappers): New subprogram within
10935 Analyze_Associations, calls the above when the formal subprogram
10936 has contracts, and expansion is enabled.
10937 (Instantiate_Formal_Subprogram): If the actual is not an entity,
10938 such as a function attribute, or a synchronized operation,
10939 create a function with an internal name and call it within the
10940 wrapper.
10941 (Analyze_Generic_Formal_Part): Analyze contracts at the end of
10942 the list of formal declarations.
10943 * sem_prag.adb (Analyze_Pre_Post_Condtion): In Ada_2020 the

10992 * exp_disp.adb, exp_disp.ads: Make TSS_Put_Image be number 10,
10993 adjusting other operations' numbers after 10. We choose 10

11053 * par-ch3.adb (P_Identifier_Declarations): Add parsing of object
11054 renamings that have neither a subtype_mark nor an
11055 access_definition. Issue an error if the version is earlier than
11056 Ada_2020, and suggest using -gnatX.
11057 * sem_ch8.adb (Analyze_Object_Renaming): Handle
11058 object_renaming_declarations that don't have an explicit
11059 subtype. Errors are issued when the name is inappropriate or
11060 ambiguous, and otherwise the Etype of the renaming entity is set
11061 from the Etype of the renamed object.
11062 * sem_util.adb (Has_Null_Exclusion): Allow for the case of no
11063 subtype given in an N_Object_Renaming_Declaration.

11094 postcondition, because declaration and body may appear in
11095 different units, and the expanded code for the body includes

11114 Check_Return_Construct_Accessibility to better reflect its
11115 purpose. Add loop to properly obtain the object declaration
11116 from an expanded extended return statement and add calls to get

11356 resets the scopes of entities associated with Loop_Id to the
11357 scope of the new function, so the resetting is not restricted to
11358 itypes, but excludes loop parameters and the function entity
