* sem_type.adb (Add_One_Interp): If a candidate operation is an
inherited interface operation that has an implementation, use the
implementation to avoid spurious ambiguities.
(Interface_Present_In_Ancestor): In case of concurrent types we can't
use the Corresponding_Record_Typ attribute to look for the interface
because it is set by the expander (and hence it is not always
available). For this reason we traverse the list of interfaces

Gary Dismukes <dismukes@adacore.com>
* sem_res.adb (Resolve_Membership_Op): In case of the membership test
"Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
the expander will generate the corresponding run-time check to evaluate
the expression.
(Resolve_Call): Check for legal type of procedure name or prefix that
appears as a trigger in a triggering alternative.
(Valid_Conversion): If expression is ambiguous and the context involves
an extension of System, remove System.Address interpretations.
(Resolve_Qualified_Expression): Reject the case of a specific-type
qualification applied to a class-wide argument. Enhance comment
to explain checking of Original_Node.
(Resolve_Type_Conversion): The location of the error message was not
general enough to handle the general case and hence it has been removed.
In addition, this patch improves the text of the message.
(Resolve_Type_Conversion): Add missing support for access to interface
types.
(Resolve_Type_Conversion): If the target is a class-wide interface type,
do not expand if the expression is the actual in a call, because proper
expansion will take place when the call itself is expanded.
(Resolve_Allocator): If the context is an unchecked conversion, the
allocator inherits its storage pool, if any, from the target type of
the conversion.

Ed Schonberg <schonberg@adacore.com>
* sem_disp.adb (Check_Controlling_Formals): Anonymous access types
used in controlling parameters exclude null because it is necessary to
read the tag to dispatch, and null has no tag.
(Override_Dispatching_Operation): If the previous operation is inherited
from an interface, it becomes hidden and does not participate in later
name resolution.

2005-09-01 Javier Miranda <miranda@adacore.com>
Gary Dismukes <dismukes@adacore.com>
* sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
access types the null-exclusion and access-to-constant attributes must
also match.
(Analyze_Return_Statement): When the result type is an anonymous access
type, apply a conversion of the return expression to the access type
to ensure that appropriate accessibility checks are performed.
(Analyze_Return_Type): For the case of an anonymous access result type,
generate the Itype and set Is_Local_Anonymous_Access on the type.
Add ??? placeholder for check to disallow returning a limited object
in Ada 2005 unless it's an aggregate or a result of a function call.
Change calls from Subtype_Mark to Result_Definition.
(Analyze_Subprogram_Body): Change formal Subtype_Mark to
Result_Definition in call to Make_Function_Specification.
(Build_Body_To_Inline): Change Set_Subtype_Mark to
Set_Result_Definition.
(Make_Inequality_Operator): Change formal Subtype_Mark to
Result_Definition in call to Make_Function_Specification.
(Process_Formals): Create the new null-excluding itype if required.
(New_Overloaded_Entity): For an entity overriding an interface primitive
check if the entity also covers other abstract subprograms in the same
scope. This is required to handle the general case, that is, overriding
other interface primitives and overriding abstract subprograms inherited
from some abstract ancestor type.
(New_Overloaded_Entity): For an overriding entity that comes from
source, note the operation that it overrides.
(Check_Conformance, Type_Conformant): Addition of one new formal
to skip controlling formals in the analysis. This is used to
handle overloading of abstract interfaces.
(Base_Types_Match): Add missing case for types imported from
limited-with clauses
(New_Overloaded_Entity): Add barrier to protect the use of
the "alias" attribute.

* sem_ch4.adb (Transform_Object_Operation): In a context off the form
V (Obj.F), the rewriting does not involve the indexed component, but
only the selected component itself.
Do not apply the transformation if the analyzed node is an actual of a
call to another subprogram.
(Complete_Object_Operation): Retain the entity of the
dispatching operation in the selector of the rewritten node. The
entity will be used in the expansion of dispatching selects.
(Analyze_One_Call): Improve location of the error message associated
with interface.
(Analyze_Selected_Component): No need to resolve prefix when it is a
function call, resolution is done when parent node is resolved, as
usual.
(Analyze_One_Call): Add a flag to suppress analysis of the first actual,
when attempting to resolve a call transformed from its object notation.
(Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
of the argument list for each interpretation of the operation.
(Try_Object_Operation): The designated type of an access parameter may
be an incomplete type obtained through a limited_with clause, in which
case the primitive operations of the type are retrieved from its full
view.
(Analyze_Call): If this is an indirect call, and the return type of the
access_to_subprogram is incomplete, use its full view if available.

Gary Dismukes <dismukes@adacore.com>
Ed Schonberg <schonberg@adacore.com>
Javier Miranda <miranda@adacore.com>
* sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
underlying type
to check if a type is Constrained in cases related to code generation
(rather than semantic checking) since otherwise we do not generate
similar code for mutable private types depending if their
discriminants are visible or not.
(Check_Abstract_Overriding): Do not complain about failure to override
the primitive operations used in dispatching selects since they will
always be overriden at the freeze point of the type.
(Access_Definition): Separate out handling for resetting the scope
of an anonymous access function result type. Retrieve the scope
of the associated function rather than using Current_Scope, which
does not have a consistent value (depends on whether we're in the
middle of analyzing formal parameters). Add ??? comment about
finding a cleaner way to handle the special cases of scope setting.
(Process_Incomplete_Dependents): A protected operation is never a
dispatching operation (only its wrapper may be).
(Build_Derived_Record_Type): In case of tagged private types that
implement interfaces add derivation of predefined primitive
operations.
(Derive_Subprograms): Replace the Is_Interface_Derivation parameter
by two parameters that are used in case of derivation from abstract
interface types: No_Predefined_Prims is used to avoid the derivation
of predefined primitives from the interface, and Predefined
Prims_Only is used to complete the derivation predefined primitives
in case of private tagged types implementing interfaces.
Fix typo in comments
(Find_Interface_In_Descendant): Protect the frontend against
wrong code with large circularity chains.
(Is_Private_Overriding): Add support for entities overriding interface
subprograms. The test failed because Entities associated with overriden
interface subprograms are always marked as hidden (and used to build
the secondary dispatch table); in this case the overriden entity is
available through the field abstract_interface_alias (cf. override_
dispatching_operation)
(Access_Definition): Set the scope of the type to Current_Scope for the
case of a function with an anonymous access result type.
(Access_Subprogram_Declaration): Handle creation of the type entity for
an access-to-function type with an anonymous access result.
(Check_Anonymous_Access_Types): Change Subtype_Mark to Result_Definition
in handling for N_Access_Function_Definition.
(Analyze_Subtype_Declaration): Modify the text of error message.
(Derived_Type_Declaration): Modify the text of error message.
(Process_Subtype): Modify the text of error message plus cleanup
of one redundant error message.
(Analyze_Component_Declaration): Code cleanup.
(Analyze_Object_Declaration): Code cleanup.
(Analyze_Subtype_Declaration): Propagate the null-exclusion
attribute in case of access types. Code cleanup.
(Array_Type_Declaration): Code cleanup.
(Process_Discriminants): Create the new null-excluding itype
if required. Code cleanup.
(Process_Subtype): Create the new null-excluding itype if
required. Code cleanup.
(Build_Derived_Record_Type): Code cleanup to avoid calling
twice the subprogram derive_subprograms in case of private
types that implement interfaces. In this particular case the
subprogram Complete_Subprograms_Derivation already does the
job associated with the second call.
* exp_strm.adb (Build_Elementary_Input_Call): Add an explicit
conversion to the full view when generating an operation for a
discriminant whose type may currently be private.

* sem_ch12.adb (Instantiate_Subprogram_Body): When creating the
defining entity for the instance body, make a new defining identifier
rather than copying the entity of the spec, to prevent accidental
sharing of the entity list.
(Check_Private_View): When exchanging views of private types, build the
list of exchanged views as a stack, to ensure that on exit the exchanges
are undone in the proper order.
(Analyze_Package_Instantiation, Analyze_Subprogram_Instantiation):
Restore the compilation environment in case of instantiation_error.
(Analyze_Generic_Subprogram_Declaration): Handle creation of type entity
for an anonymous access result.
(Instantiate_Generic_Subprogram): Subtype_Mark => Result_Definition

Ed Schonberg <schonberg@adacore.com>
* sem_ch10.adb (In_Chain): Moved from the scope of a subprogram to
become local to the whole package.
(Install_Limited_Withed_Unit): Instead of unchaining real entities if
the package was already analyzed the new algorithm "replaces" the
real entities by the shadow ones. This is required to ensure that
the order of these entities in the homonym chains does not change;
otherwise we can have undefined references at linking time because
in case of conflicts the external name of the entities will have
a suffix that depends on the order of the entities in the chain.
(Remove_Limited_With_Clause): Complementary code that completes the
new algorithm and replaces the shadow entities by the real ones.
(Install_Limited_Withed_Unit): When unchaining entities before the
installation of the shadow entities, only regular entities of the
public part must be taken into account. This is required to
keep this routine in synch with the work done by Remove_Limited_
With_Clause
(Install_Limited_With_Clause): Introduce implicit limited_with_clause
even if unit is analyzed, because the analysis of the unit is
idempotent in any case, and the limited view of the unit may have to
be installed for proper visibility.
(Expand_Limited_With_Clause): Even if the unit in the implicit
with_clause has been analyzed already, a limited view of the package
must be built for the current context, if it does not exist yet.

* exp_ch6.adb (Expand_Call): If an actual is a function call rewritten
from object notation, the original node is unanalyzed and carries no
semantic information, so that accessiblity checks must be performed on
the type of the actual itself.
(Expand_N_Subprogram_Declaration): Change last actual parameter for
compatibility with Build_Protected_Sub_Specification.
(Check_Overriding_Inherited_Interfaces): Add suport to handle
overloaded primitives.
(Register_Interface_DT_Entry): Use the new name of the formal
the the calls to Expand_Interface_Thunk
* exp_dbug.ads: Augment comments on encoding of protected types to
include the generation of dispatching subprograms when the type
implements at least one interface.
* lib.ads: Extend information in Load_Stack to include whether a given
load comes from a Limited_With_Clause.
* lib-load.adb (From_Limited_With_Chain): New predicate to determine
whether a potential circularity is harmless, because it includes units
loaded through a limited_with clause. Extends previous treatment which
did not handle properly arbitrary combinations of limited and
non-limited clauses.
