        * sem_warn.adb (Check_References): When checking for an unused
        in-out parameter of a class- wide type, use its type to determine

2015-03-02  Ed Schonberg  <schonberg@adacore.com>

        * exp_ch7.adb (Make_Set_Finalize_Address_Call): Use underlying
        type to retrieve designated type, because the purported access
        type may be a partial (private) view, when it is declared in
        the private part of a nested package, and finalization actions
        are generated when completing compilation of enclosing unit.

        wrapped subprogram.
        (Set_DTC_Entity_Value): Propagate the DTC
        value to the wrapped entity.
        * sem_ch13.adb (Build_Invariant_Procedure): Append the code
        associated with invariants of progenitors.
        * sem_ch3.adb (Build_Derived_Record_Type): Inherit type invariants

        * sem_prag.adb (Pragma_Invariant) Allow invariants in interface
        types but do not build their invariant procedure since their

        * sem_attr.adb (Analyze_Attribute): Factor out heavily indented
        code in Denote_Same_Function.  Do not analyze attribute 'Result

        * a-strsea.adb (Find_Token): Ensure that the range of iteration
        does not perform any improper character access. This prevents
        erroneous access in the unusual case of an empty string target
        and a From parameter less than Source'First.

2015-03-02  Robert Dewar  <dewar@adacore.com>

        * elists.adb (List_Length): Fix incorrect result.

2015-03-02  Bob Duff  <duff@adacore.com>

        * sem_ch6.adb (Check_Private_Overriding): Refine the legality
        checks here. It used to check that the function is merely
        overriding SOMEthing. Now it checks that the function is
        overriding a corresponding public operation. This is a correction
        to the implementation of the rule in RM-3.9.3(10).

2015-03-02  Pierre-Marie de Rodat  <derodat@adacore.com>

        * gcc-interface/utils.c (gnat_pushdecl): For non-artificial pointer
        types, preserve the original type and create copies just like the C
        front-end does.  For artificial ones, do not define a name for
        the original type.
        (create_type_decl): When gnat_pushdecl made the input type the
        original type for the new declaration, do not define a stub
        declaration for it.
        * gcc-interface/utils2.c (build_binary_op): Accept two different
        pointer types when they point to the same type.

2015-03-02  Hristian Kirtchev  <kirtchev@adacore.com>

        * exp_attr.adb (Expand_N_Attribute_Reference, case Input): When
        expanding a 'Input attribute reference for a class-wide type,
        do not generate a separate object declaration for the controlling
        tag dummy object; instead, generate the expression inline in the
        dispatching call. Otherwise, the declaration (which involves a
        call to String'Input, returning a dynamically sized value on the
        secondary stack) will be expanded outside of proper secondary
        stack mark/release operations, and will thus cause a secondary
        stack leak.

2015-03-02  Hristian Kirtchev  <kirtchev@adacore.com>

        * checks.adb (Add_Validity_Check): Change the names of all
        formal parameters to better illustrate their purpose. Update
        the subprogram documentation. Update all occurrences of the

2015-01-06  Robert Dewar  <dewar@adacore.com>

        msg for attempted USE of generic subprogram or subprogram.

2015-01-06  Robert Dewar  <dewar@adacore.com>

        * s-valllu.adb, a-tiinau.adb, a-timoau.adb, a-ztinau.adb, a-ztmoau.adb,
        s-valuns.adb, s-valrea.adb, a-wtflau.adb, a-tiflau.adb, a-ztflau.adb,
        a-wtinau.adb, a-wtmoau.adb: Document recognition of : in place of #.

2015-01-06  Ed Schonberg  <schonberg@adacore.com>

        * sem_ch13.adb (Analyze_Aspect_Specifications): For aspects
        that specify stream subprograms, if the prefix is a class-wide
        type then the generated attribute definition clause must apply
        to the same class-wide type.
        (Default_Iterator): An iterator defined by an aspect of some

2015-01-06  Arnaud Charlet  <charlet@adacore.com>

        * gnat1drv.adb: Minor: complete previous change.

2015-01-06  Olivier Hainque  <hainque@adacore.com>

        * set_targ.ads (C_Type_For): New function. Return the name of
        a C type supported by the back-end and suitable as a basis to
        construct the standard Ada floating point type identified by
        the T parameter. This is used as a common ground to feed both
        ttypes values and the GNAT tree nodes for the standard floating
        point types.
        * set_targ.adb (Long_Double_Index): The index at which "long
        double" gets registered in the FPT_Mode_Table. This is useful to
        know whether we have a "long double" available at all and get at
        it's characteristics without having to search the FPT_Mode_Table
        when we need to decide which C type should be used as the
        basis for Long_Long_Float in Ada.
        (Register_Float_Type): Fill Long_Double_Index.
        (FPT_Mode_Index_For): New function. Return the index in
        FPT_Mode_Table that designates the entry corresponding to the
        provided C type name.
        (FPT_Mode_Index_For): New function. Return the index in
        FPT_Mode_Table that designates the entry for a back-end type
        suitable as a basis to construct the standard Ada floating point
        type identified by the input T parameter.
        (elaboration code): Register_Back_End_Types unconditionally,
        so C_Type_For can operate regardless of -gnateT. Do it
        early so we can query it for the floating point sizes, via
        FPT_Mode_Index_For. Initialize Float_Size, Double_Size and
        Long_Double_Size from the FPT_Mode_Table, as cstand will do.
        * cstand.adb (Create_Float_Types): Use C_Type_For to determine
        which C type should be used as the basis for the construction
        of the Standard Ada floating point types.
        * get_targ.ads (Get_Float_Size, Get_Double_Size,
        Get_Long_Double_Size): Remove.
        * get_targ.adb: Likewise.

        package.

        returning anonymous access in RCI unit.

        * sem_ch6.adb (New_Overloaded_Entity): In GNATprove mode, a
        function wrapper may be a homonym of another local declaration.
        * sem_ch8.adb (Analyze_Subprogram_Renaming): In GNATprove mode,
        build function and operator wrappers after the actual subprogram
        has been resolved, and replace the standard renaming declaration
        with the declaration of wrapper.
        * sem_ch12.ads (Build_Function_Wrapper, Build_Operator_Wraooer):
        make public for use elsewhere.
        * sem_ch12.adb (Build_Function_Wrapper, Build_Operator_Wraooer):
        rewrite, now that actual is fully resolved when wrapper is
        constructed.

2015-01-06  Javier Miranda  <miranda@adacore.com>

        cannot be read.

2015-01-06  Ed Schonberg  <schonberg@adacore.com>

        * sem_ch4.adb (Analyze_One_Call): If formal has an incomplete

        error, but a case of use of incomplete type in a predicate or
        invariant expression.
