* exp_ch3.adb (Build_Init_Statements): Add extra condition to deal with
per-object constrained components where the discriminant is of an
Access type.
(Build_Record_Init_Proc): Add condition to prevent the inheritance of
the parent initialization procedure for derived Unchecked_Unions.
Instead, derived Unchecked_Unions build their own initialization
procedure.
(Build_Variant_Record_Equality): Implement Unchecked_Union equality.
Check the body of the subprogram for details.
(Freeze_Record_Type): Prevent the inheritance of discriminant checking
functions for derived Unchecked_Union types by introducing a condition.

(Make_Eq_Case): Rename formal parameter Node to E in function signature.
Add formal parameter Discr to function signature. Discr is used to
control the generated case statement for Unchecked_Union types.
(Make_Eq_If): Rename formal parameter Node to E in function signature.
* exp_ch4.adb (Build_Equality_Call): Implement equality calls for
Unchecked_Unions.

subtype mark is a constrained Unchecked_Union and the expression lacks
inferable discriminants, and build a Raise_Program_Error node.
(Expand_N_Op_Eq): Add function Has_Unconstrained_UU_Component. Used
to detect types that contain components of unconstrained Unchecked_Union
subtype. Add condition to detect equality between types that have an
unconstrained Unchecked_Union component, and build a Raise_Program_Error

that lack inferable discriminants, and build a Raise_Program_Error node.
Otherwise build a TSS equality function call.
(Expand_N_Type_Conversion): Add condition to detect illegal conversions
from a derived Unchecked_Union to an unconstrained non-Unchecked_Union
with the operand lacking inferable discriminants, and build a Raise_
Program_Error node.

composite equality.
(Has_Inferable_Discriminants): Implement new predicate for objects and
expressions of Unchecked_Union type. Check the body of subprogram for
details.
(Has_Unconstrained_UU_Components): Add function
Component_Is_Unconstrained_UU. It is used to detect whether a single
component is of an unconstrained Unchecked_Union subtype. Add function
Variant_Is_Unconstrained_UU. It is used to detect whether a single
component inside a variant is of an unconstrained Unchecked_Union type.

inferred discriminant values. Add condition to generate a case
statement with an inferred discriminant as the switch.
(Make_Component_List_Assign): Introduce a Boolean flag that determines
the behaviour of the subprogram in the presence of an Unchecked_Union.
Add condition to trigger the usage of the inferred discriminant value
as the generated case statement switch.
(Make_Field_Assign): Introduce a Boolean flag that determines the
behaviour of the subprogram in the presence of an Unchecked_Union. Add
condition to trigger the usage of the inferred discriminant value as
the right-hand side of the generated assignment.

parameter generation when dealing with Unchecked_Unions.

checks for Unchecked_Unions.
* einfo.ads: Update comment on usage of flag Has_Per_Object_Constraint
* exp_attr.adb (Expand_N_Attribute_Reference): Produce
Raise_Program_Error nodes for the execution of Read and Write
attributes of Unchecked_Union types and the execution of Input and
Output attributes of Unchecked_Union types that lack default
discriminant values.
* sem_prag.adb (Analyze_Pragma): Remodel the analysis of pragma
Unchecked_Union. Add procedure Check_Component. It is used to inspect
per-object constrained components of Unchecked_Unions for being
Unchecked_Unions themselves. Add procedure Check_Variant. It is used to
check individual components withing a variant.
* sem_res.adb (Resolve_Comparison_Op): Remove guard that prevents
comparison of Unchecked_Unions.
(Resolve_Equality_OP): Remove guard that prevents equality between
Unchecked_Unions.
* sem_util.adb (Build_Component_Subtype): Add guard to prevent creation
of component subtypes for Unchecked_Union components.

since it is the actual subtype.
* sem_ch12.adb (Instantiate_Type): Add condition to detect the correct
pass of Unchecked_Union subtypes as generic actuals to formal types
that lack known_discriminant_parts or that are derived Unchecked_Union
types, and do nothing. In any other case, produce an error message.

Contains_POC. It determines whether a constraint uses the discriminant
of an enclosing record type.

Union subtypes.
