3 * sem_ch3.adb (Build_Derived_Concurrent_Type): Add a couple of
4 local variables and use them. When the derived type fully
5 constrains the parent type, rewrite it as a subtype of an
6 implicit (unconstrained) derived type instead of the other way
7 around.

28 private, do not re-derive the parent type but instead constrain
29 an existing underlying full view.
30 (Prepare_Private_Subtype_Completion): Do not get to the
31 underlying full view, if any. Set the full view on the private
32 subtype here.

527 2019-07-23 Ed Schonberg <schonberg@adacore.com>
529 * aspects.ads: New table Operational_Aspect, used to distinguish
530 between aspects that are view-specific, such as those related to
531 iterators, and representation aspects that apply to all views of
532 a type.
533 * aspects.adb (Find_Aspect): If the aspect being sought is
534 operational, do not ecamine the full view of a private type to
535 retrieve it.
536 * sem_ch5.adb (Analyze_Iterator_Specification): Improve error
537 message when the intended domain of iteration does not implement
538 the required iterator aspects.
540 2019-07-23 Yannick Moy <moy@adacore.com>
542 * sem_spark.ads (Is_Local_Context): New function.

574 'Valid as a replacement for a range check on a discrete type
575 when the bounds of the range are given by type conversions,
576 because in such a case there are distinct types involved and the
577 subbested attribute replacement would be misplaced.
579 2019-07-22 Yannick Moy <moy@adacore.com>
581 * sem_spark.adb (Get_Root_Object, Is_Path_Expression,
582 Is_Subpath_Expression): Add parameter Is_Traversal to adapt

584 function.
585 (Read_Indexes): Handle the case of an if-expression or

609 checks on discrete types. Remove obsolete code for

611 for conversions involving fixed-point types.
613 2019-07-22 Eric Botcazou <ebotcazou@adacore.com>
615 * sprint.ads: Fix pasto in comment.
617 2019-07-22 Javier Miranda <miranda@adacore.com>
619 * sem_res.adb (Resolve_Actuals): Replace code that displaces the

622 handling all cases).
624 2019-07-22 Eric Botcazou <ebotcazou@adacore.com>
626 * sprint.adb (Sprint_Node_Actual)
627 <N_Decimal_Fixed_Point_Definition>: Swap a couple of spaces.

641 libgnat/s-vallli.ads, libgnat/s-valllu.ads,
642 libgnat/s-valrea.ads, libgnat/s-valuns.ads,
643 libgnat/s-valwch.ads: Change categorization of packages that
644 implement attribute 'Value from Pure to Preelaborate, to prevent
645 undesirable optimizations when the evaluation of the attribute
646 raises Constraint_Error, but subsequent use of the result of
647 this evsaluation is removed by a subsequent optimization.
649 2019-07-22 Ed Schonberg <schonberg@adacore.com>
651 * sem_warn.adb (Check_References): Do not emit s warning on a
652 referenced entity with no explicit assignment if the type of the

663 * libgnat/s-imenne.adb (Image_Enumeration_8,

665 Index_Table with range Natural'First .. Names'Length since in
666 the worst case all the literals of the enumeration type would be
667 single letter literals and the Table built by the frontend would
668 have as many components as the length of the names string. As a
669 result of this enhancement, the internal tables declared using
670 Index_Table have a length closer to the real needs, thus
671 avoiding the declaration of large arrays on 32-bit CCG targets.
673 2019-07-22 Yannick Moy <moy@adacore.com>
675 * sem_ch3.adb (Constrain_Access): Issue a message about ignored

708 * sem_ch3.adb (Convert_Bound): Subsidiary of
709 Floating_Point_Type_Declaration, to handle properly range

724 * exp_ch5.adb (Expand_N_Case_Statement): In the case where a
725 case statement is rewritten as an equivalent if statement,
726 inherit the From_Condition_Expression flag from the case
727 statement.
729 2019-07-22 Eric Botcazou <ebotcazou@adacore.com>
731 * sem_ch8.adb (Check_Constrained_Object): Further extend the

783 stqtement list, in which the prefix of the selected component is
784 the actual for an out parameter.

837 moved to GNATprove backend.
838 * sem_spark.ads, sem_spark.adb (Sem_SPARK): Is now a generic
839 unit. Takes as parameters:
840 - Retysp which is used to query the most underlying type
841 visible in SPARK. We do not introduce aliasing checks for
842 types which are not visibly deep.
843 - Component_Is_Visible_In_SPARK is used to avoid doing pointer
844 aliasing checks on components which are not visible in SPARK.

846 analysis. Error messages for failed aliasing checks are only
847 output in this case.
848 Additionally, errors on constructs not supported in SPARK are

855 on deep types inside SPARK semantic checkings.
