1084         that specify stream subprograms, if the prefix is a class-wide
1085         type then the generated attribute definition clause must apply
1086         to the same class-wide type.

1096
1097         * set_targ.ads (C_Type_For): New function. Return the name of
1098         a C type supported by the back-end and suitable as a basis to
1099         construct the standard Ada floating point type identified by
1100         the T parameter. This is used as a common ground to feed both
1101         ttypes values and the GNAT tree nodes for the standard floating
1102         point types.
1103         * set_targ.adb (Long_Double_Index): The index at which "long
1104         double" gets registered in the FPT_Mode_Table. This is useful to
1105         know whether we have a "long double" available at all and get at
1106         it's characteristics without having to search the FPT_Mode_Table
1107         when we need to decide which C type should be used as the
1108         basis for Long_Long_Float in Ada.
1109         (Register_Float_Type): Fill Long_Double_Index.
1110         (FPT_Mode_Index_For): New function. Return the index in
1111         FPT_Mode_Table that designates the entry corresponding to the
1112         provided C type name.
1113         (FPT_Mode_Index_For): New function. Return the index in
1114         FPT_Mode_Table that designates the entry for a back-end type
1115         suitable as a basis to construct the standard Ada floating point
1116         type identified by the input T parameter.
1117         (elaboration code): Register_Back_End_Types unconditionally,
1118         so C_Type_For can operate regardless of -gnateT. Do it
1119         early so we can query it for the floating point sizes, via
1120         FPT_Mode_Index_For. Initialize Float_Size, Double_Size and
1121         Long_Double_Size from the FPT_Mode_Table, as cstand will do.
1122         * cstand.adb (Create_Float_Types): Use C_Type_For to determine
1123         which C type should be used as the basis for the construction
1124         of the Standard Ada floating point types.
1125         * get_targ.ads (Get_Float_Size, Get_Double_Size,
1126         Get_Long_Double_Size): Remove.
1127         * get_targ.adb: Likewise.

1134         package.
1135         (Validate_RCI_Subprogram_Declaration): Reject illegal function
1136         returning anonymous access in RCI unit.

1139
1140         * sem_ch6.adb (New_Overloaded_Entity): In GNATprove mode, a
1141         function wrapper may be a homonym of another local declaration.
1142         * sem_ch8.adb (Analyze_Subprogram_Renaming): In GNATprove mode,
1143         build function and operator wrappers after the actual subprogram
1144         has been resolved, and replace the standard renaming declaration
1145         with the declaration of wrapper.
1146         * sem_ch12.ads (Build_Function_Wrapper, Build_Operator_Wraooer):
1147         make public for use elsewhere.
1148         * sem_ch12.adb (Build_Function_Wrapper, Build_Operator_Wraooer):
1149         rewrite, now that actual is fully resolved when wrapper is
1150         constructed.

1175         copy with the type of the component even in compile-only mode,
1176         to detect potential accessibility errors.
