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
        container type T must have a first parameter of type T, T'class,

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.

        * 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.
