Yes, an annoying problem, regression from 3.x.

New Revision: 111062

URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=111062
Log:
2006-02-13  Ed Schonberg  <schonberg@adacore.com>
            Javier Miranda  <miranda@adacore.com>
            Robert Dewar  <dewar@adacore.com>
            Gary Dismukes  <dismukes@adacore.com>

        * exp_ch6.adb (Expand_Inlined_Call): Handle calls to functions that
        return unconstrained arrays.
        Update comments.
        (Expand_Call):  An indirect call through an access parameter of a
        protected operation is not a protected call.
        Add circuit to raise CE in Ada 2005 mode following call
        to Raise_Exception.
        (Register_DT_Entry): Do nothing if
        the run-time does not give support to abstract interfaces.
        (Freeze_Subprogram): In case of dispatching operations, do not generate
        code to register the operation in the dispatch table if the source
        is compiled with No_Dispatching_Calls.
        (Register_Predefined_DT_Entry): Generate code that calls the new
        run-time subprogram Set_Predefined_Prim_Op_Address instead of
        Set_Prim_Op_Address.

        * sem_ch5.adb (Analyze_Assignment_Statement): Do not apply length
checks
        on array assignments if the right-hand side is a function call that has
        been inlined. Check is performed on the assignment in the block.
        (Process_Bounds): If bounds and range are overloaded, apply preference
        rule for root operations to disambiguate, and diagnose true ambiguity.
        (Analyze_Assignment): Propagate the tag for a class-wide assignment
with
        a tag-indeterminate right-hand side even when Expander_Active is True.
        Needed to ensure that dispatching calls to T'Input are allowed and
        get the tag of the target class-wide object.

        * sem_ch6.adb (New_Overloaded_Entity): Handle entities that override
        an inherited primitive operation that already overrides several
        abstract interface primitives. For transitivity, the new entity must
        also override all the abstract interface primitives covered by the
        inherited overriden primitive.
        Emit warning if new entity differs from homograph in same scope only in
        that one has an access parameter and the other one has a parameter of
        a general access type with the same designated type, at the same
        position in the signature.
        (Make_Inequality_Operator): Use source locations of parameters and
        subtype marks from corresponding equality operator when creating the
        tree structure for the implicit declaration of "/=". This does not
        change anything in behaviour except that the decoration of the
        components of the subtree created for "/=" allows ASIS to get the
        string images of the corresponding identifiers.
        (Analyze_Return_Statement): Remove '!' in warning message.
        (Check_Statement_Sequence): Likewise.
        (Analyze_Subprogram_Body): For an access parameter whose designated
type
        is an incomplete type imported through a limited_with clause, use the
        type of the corresponding formal in the body.
        (Check_Returns): Implicit return in No_Return procedure now raises
        Program_Error with a compile time warning, instead of beging illegal.
        (Has_Single_Return):  Function returning unconstrained type cannot be
        inlined if expression in unique return statement is not an identifier.
        (Build_Body_To_Inline): It is possible to inline a function call that
        returns an unconstrained type if all return statements in the function
        return the same local variable. Subsidiary procedure Has_Single_Return
        verifies that the body conforms to this restriction.

        * sem_res.adb (Resolve_Equality_Op): If the operands do not have the
        same type, and  one of them is of an anonymous access type, convert
        the other operand to it, so that this is a valid binary operation for
        gigi.
        (Resolve_Type_Conversion): Handle subtypes of protected types and
        task types when accessing to the corresponding record type.
        (Resolve_Allocator): Add '\' in 2-line warning message.
        Remove '!' in warning message.
        (Resolve_Call): Add '\' in 2-line warning message.
        (Valid_Conversion): Likewise.
        (Resolve_Overloaded_Selected_Component): If disambiguation succeeds,
the
        resulting type may be an access type with an implicit dereference.
        Obtain the proper component from the designated type.
        (Make_Call_Into_Operator): Handle properly a call to predefined
equality
        given by an expanded name with prefix Standard, when the operands are
        of an anonymous access type.
        (Check_Fully_Declared_Prefix): New procedure, subsidiary of Resolve_
        Explicit_Dereference and Resolve_Selected_Component, to verify that the
        prefix of the expression is not of an incomplete type. Allows full
        diagnoses of all semantic errors.
        (Resolve_Actuals): If the actual is an allocator whose directly
        designated type is a class-wide interface we build an anonymous
        access type to use it as the type of the allocator. Later, when
        the subprogram call is expanded, if the interface has a secondary
        dispatch table the expander will add a type conversion to force
        the displacement of the pointer.
        (Resolve_Call): If a function that returns an unconstrained type is
        marked Inlined_Always and inlined, the call will be inlined and does
        not require the creation of a transient scope.
        (Check_Direct_Boolean_Op): Removed
        (Resolve_Comparison_Op): Remove call to above
        (Resolve_Equality_Op): Remove call to above
        (Resolve_Logical_Op): Inline above, since this is only call.
        (Valid_Conversion): Handle properly conversions between arrays of
        convertible anonymous access types.

        PR ada/25885

        (Set_Literal_String_Subtype): If the lower bound is not static, wrap
        the literal in an unchecked conversion, because GCC 4.x needs a static
        value for a string bound.
