is aliased, a constrained nominal subtype does not force a result
of False, and a dereference of an extended access value is
aliased. The last point is somewhat subtle. This is how we prevent
covert fat-to-nonfat type conversions via things like
"Not_Extended_Type'(Extended_Ptr.all'Access)" or passing
Extended_Ptr.all as an actual parameter corresponding to an
explicitly aliased formal parameter.

need to check for Is_Library_Level_Entity, because
No_Heap_Finalization requires that. And if we ever change
No_Heap_Finalization to allow nested access types, we will still
want to pass null. Note that the comment "Such a type lacks a
collection." is incorrect in the case of Finalize_Storage_Only;
such types have a collection.

* 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.

subprogram is to be inserted in the tree. If one such subprogram

procedures for composite type and for a component type thereof),
then we want to avoid use-before-definition problems that can
result from inserting the caller ahead of the callee.

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
