        * exp_aggr.ads (Is_Delayed_Conditional_Expression): New predicate.
        * exp_aggr.adb (Convert_To_Assignments.Known_Size): Likewise.
        (Convert_To_Assignments): Climb the parent chain, looking through
        qualified expressions and dependent expressions of conditional
        expressions, to find out whether the expansion may be delayed.
        Call Known_Size for this in the case of an object declaration.
        If so, set Expansion_Delayed on the aggregate as well as all the
        intermediate conditional expressions.
        (Initialize_Component): Reset the Analyzed flag on an initialization
        expression that is a conditional expression whose expansion has been
        delayed.

        (Expand_N_Case_Expression): Deal with expressions whose expansion
        has been delayed by waiting for the rewriting of their parent as
        an assignment statement and then optimizing the assignment.
        (Expand_N_If_Expression): Likewise.
        (Expand_N_Qualified_Expression): Do not apply a predicate check to

        * gen_il-gen-gen_nodes.adb (N_If_Expression): Add Expansion_Delayed

2024-05-20  Gary Dismukes  <dismukes@adacore.com>

        * exp_aggr.adb (Expand_Container_Aggregate): Add top-level
        variables Choice_{Lo|Hi} and Int_Choice_{Lo|Hi} used for
        determining the low and high bounds of component association
        choices. Replace code for determining whether we have an indexed
        aggregate with call to new function Sem_Aggr.Is_Indexed_Aggregate.
        Remove test of whether Empty_Subp is a function, since it must be
        a function. Move Default and Count_Type to be locals of a new
        block enclosing the code that creates the object to hold the
        aggregate length, and set them according to the default and type
        of the Empty function's parameter when present (and to Empty and
        Standard_Natural otherwise). Use Siz_Exp for the aggregate length
        when set, and use Empty's default length when available, and use
        zero for the length otherwise. In generating the call to the
        New_Indexed function, use the determined lower and upper bounds if
        determined earlier by Aggregate_Size, and otherwise compute those
        from the index type's lower bound and the determined aggregate
        length. In the case where a call to Empty is generated and the
        function has a formal parameter, pass the value saved in Siz_Decl
        (otherwise the parameter list is empty). Remove code specific to
        making a parameterless call to the Empty function. Extend the code
        for handling positional container aggregates to account for types
        that define Assign_Indexed, rather than just Add_Unnamed, and in
        the case of indexed aggregates, create a temporary object to hold
        values of the aggregate's key index, and initialize and increment
        that temporary for each call generated to the Assign_Indexed
        procedure. For named container aggregates that have key choices
        given by ranges, call Expand_Range_Component to generate a loop
        that will call the appropriate insertion procedure for each value
        of the range. For indexed aggregates with a Component_Associations
        list, set and use the Assign_Indexed procedure for each component
        association, whether or not there's an iterator specification.
        (Add_Range_Size): Add code to determine the low and high bounds of
        the range and capture those in up-level variables when their value
        is less than or greater than (respectively) the current minimum
        and maximum bounds values.
        (Aggregate_Size): Separately handle the case where a single choice
        is of a discrete type, and call Add_Range_Size to take its value
        into consideration for determination of min and max bounds of the
        aggregate. Add comments in a couple of places.
        (Build_Siz_Exp): Remove the last sentence and "???" from the
        comment that talks about accumulating nonstatic sizes, since that
        sentence seems to be obsolete. Record the low and high bound
        values in Choice_Lo and Choice_Hi in the case of a nonstatic
        range.
        (Expand_Iterated_Component): Set the Defining_Identifier of the
        iterator specification to the Loop_Id in the
        N_Iterated_Component_Association case.
        (Expand_Range_Component): Procedure unnested from the block
        handling indexed aggregates in Expand_Container_Aggregate, and
        moved to top level of that procedure so it can also be called for
        Add_Named cases. A formal parameter Insert_Op is added, and
        existing calls to this procedure are changed to pass the
        appropriate insertion procedure's Entity.
        * sem_aggr.ads: Add with_clause for Sinfo.Nodes.
        (Is_Indexed_Aggregate): New function for use by
        Resolve_Container_Aggregate and Expand_Container_Aggregate.
        * sem_aggr.adb: Add with_clause for Sem_Ch5. Move with_clause for
        Sinfo.Nodes to sem_aggr.ads.
        (Is_Indexed_Aggregate): New function to determine whether a
        container aggregate is a container aggregate (replacing local
        variable of the same name in Resolve_Container_Aggregate).
        (Resolve_Iterated_Association): Remove part of comment saying that
        a Key_Expression is always present. Set Parent field of the copy
        of a component association with a loop parameter specification. On
        the setting of Loop_Param_Id, account for a
        Loop_Parameter_Specification being changed into an
        Iterator_Specification as a result of being analyzed. Only call
        Preanalyze_And_Resolve on Key_Expr when a key expression is
        actually present. Remove loop for handling choices for the case of
        an N_Component_Association with a Defining_Identifier (there
        shouldn't be more than one choice in this case, and add an
        assertion to ensure that). Also add code here to handle the case
        where the choice is a function call, creating an
        iterator_specification analyzing it, and call
        Resolve_Iterated_Association recursively to process it. Add error
        check to enforce RM22 4.3.5(27), which requires that the type of
        the loop parameter must be the same as the key type when there is
        no key expression and the aggregate is an indexed aggregate or has
        an Add_Named op.
        (Resolve_Container_Aggregate): In the Add_Unnamed case, call
        Resolve_Iterated_Association for both
        N_Iterated_Element_Association and N_Component_Association (rather
        than just the latter). Remove error check for nonstatic choices in
        component associations in Add_Named cases (multiple named
        nonstatic associations are fine except in indexed aggregates).
        Remove local variable Is_Indexed_Aggregate, replaced with new
        library-level function of the same name, and add test of
        Is_Indexed_Aggregate in the case where the aggregate type has an
        Assign_Indexed operation, as a guard for doing error checks for
        indexed aggregates. For indexed aggregate resolution, do not call
        Analyze_And_Resolve on the expression of an
        N_Component_Association in the "box association" case. Move error
        checks for indexed aggregates with iterated associations that flag
        cases where an association is a loop_parameter_specification with
        an iterator filter or a key expression (violation of RM22
        4.3.5(28/5)), from the loop that checks for contiguous and
        nonoverlapping choices and into the preceding association loop
        after the call to Resolve_Iterated_Association. The RM reference
        is added to the error-message strings.

        the list.
        * sem_ch5.adb (Analyze_Assignment): Normally a limited-type
        assignment is illegal. Relax this rule if Comes_From_Source is

2024-05-14  Gary Dismukes  <dismukes@adacore.com>

        * exp_util.adb (Find_Hook_Context): Exclude N_*Aggregate Nkinds
        of Parent (Par) from the early return in the second loop of the

2024-05-14  Steve Baird  <baird@adacore.com>

        * exp_attr.adb: Replace 6 "not Present" tests with equivalent calls to "No".

        * exp_ch3.adb (Expand_N_Object_Declaration): Examine the Expression
        field after the call to Default_Initialize_Object in order to set
        Is_Known_Null, as well as Is_Known_Non_Null, on an access object.

2024-05-14  Steve Baird  <baird@adacore.com>

        * exp_attr.adb: Change name of package Cached_Streaming_Ops to
        reflect the fact that it is now also used for Put_Image
        procedures. Similarly change other "Streaming_Op" names therein.
        Add Validate_Cached_Candidate procedure to detect case where a
        subprogram found in the cache cannot be reused. Add new generic
        procedure Build_And_Insert_Type_Attr_Subp; the "Build" part is
        handled by just calling a formal procedure; the bulk of this
        (generic) procedure's code has to with deciding where in the tree
        to insert the newly-constructed subprogram. Replace each later
        "Build" call (and the following Insert_Action or
        Compile_Stream_Body_In_Scope call) with a declare block that
        instantiates and then calls this generic procedure. Delete the
        now-unused procedure Compile_Stream_Body_In_Scope. A constructed
        subprogram is entered in the appropriate cache if the
        corresponding type is untagged; this replaces more complex tests.
        A new function Interunit_Ref_OK is added to determine whether an
        attribute reference occuring in one unit can safely refer to a
        cached subprogram declared in another unit.
        * exp_ch3.adb (Build_Predefined_Primitive_Bodies): A formal
        parameter was deleted, so delete the corresponding actual in a
        call.
        * exp_put_image.adb (Build_Array_Put_Image_Procedure): Because the
        procedure being built may be referenced more than once, the
        generated procedure takes its source position info from the type
        declaration instead of the (first) attribute reference.
        (Build_Record_Put_Image_Procedure): Likewise.
        * exp_put_image.ads (Build_Array_Put_Image_Procedure): Eliminate
        now-unused Nod parameter.
        (Build_Record_Put_Image_Procedure): Eliminate now-unused Loc parameter.
        * sem_ch3.adb (Constrain_Discriminated_Type): For declaring a
        subtype with a discriminant constraint, ignore privacy if
        Comes_From_Source is false (as is already done if Is_Instance is
        true).
        * sem_res.adb (Resolve): When passed two type entities that have
        the same underlying base type, Sem_Type.Covers may return False in
        some cases because of privacy. [This can happen even if
        Is_Private_Type returns False both for Etype (N) and for Typ;
        Covers calls Base_Type, which can take a non-private argument and
        yield a private result.] If Comes_From_Source (N) is False
        (e.g., for a compiler-generated Put_Image or streaming subprogram), then
        avoid that scenario by not calling Covers. Covers already has tests for
        doing this sort of thing (see the calls therein to Full_View_Covers),
        but the Comes_From_Source test is too coarse to apply there. So instead
        we handle the problem here at the call site.
        (Original_Implementation_Base_Type): A new function. Same as
        Implementation_Base_Type except if the Original_Node attribute of
        a non-derived type declaration indicates that it once was a derived
        type declaration. Needed for looking through privacy.
        (Valid Conversion): Ignore privacy when converting between different views
        of the same type if Comes_From_Source is False for the conversion.
        (Valid_Tagged_Conversion): An ancestor-to-descendant conversion is not an
        illegal downward conversion if there is no type extension involved
        (because the derivation was from an untagged view of the parent type).

2024-05-14  Steve Baird  <baird@adacore.com>

        * sem_ch5.adb (Analyze_Case_Statement): Emit a message and return
        early in the case where general case statements are allowed but
        the selector expression is of a private type. This is done to
        avoid a bugbox.

2024-05-14  Justin Squirek  <squirek@adacore.com>
