1066
1067         * sem_ch13.adb (Analyze_Aspect_Specifications): For aspects
1068         that specify stream subprograms, if the prefix is a class-wide
1069         type then the generated attribute definition clause must apply
1070         to the same class-wide type.
1071         (Default_Iterator): An iterator defined by an aspect of some
1072         container type T must have a first parameter of type T, T'class,
1073         or an access to such (from code reading RM 5.5.1 (2/3)).

1080
1081         * set_targ.ads (C_Type_For): New function. Return the name of
1082         a C type supported by the back-end and suitable as a basis to
1083         construct the standard Ada floating point type identified by
1084         the T parameter. This is used as a common ground to feed both
1085         ttypes values and the GNAT tree nodes for the standard floating
1086         point types.
1087         * set_targ.adb (Long_Double_Index): The index at which "long
1088         double" gets registered in the FPT_Mode_Table. This is useful to
1089         know whether we have a "long double" available at all and get at
1090         it's characteristics without having to search the FPT_Mode_Table
1091         when we need to decide which C type should be used as the
1092         basis for Long_Long_Float in Ada.
1093         (Register_Float_Type): Fill Long_Double_Index.
1094         (FPT_Mode_Index_For): New function. Return the index in
1095         FPT_Mode_Table that designates the entry corresponding to the
1096         provided C type name.
1097         (FPT_Mode_Index_For): New function. Return the index in
1098         FPT_Mode_Table that designates the entry for a back-end type
1099         suitable as a basis to construct the standard Ada floating point
1100         type identified by the input T parameter.
1101         (elaboration code): Register_Back_End_Types unconditionally,
1102         so C_Type_For can operate regardless of -gnateT. Do it
1103         early so we can query it for the floating point sizes, via
1104         FPT_Mode_Index_For. Initialize Float_Size, Double_Size and
1105         Long_Double_Size from the FPT_Mode_Table, as cstand will do.
1106         * cstand.adb (Create_Float_Types): Use C_Type_For to determine
1107         which C type should be used as the basis for the construction
1108         of the Standard Ada floating point types.
1109         * get_targ.ads (Get_Float_Size, Get_Double_Size,
1110         Get_Long_Double_Size): Remove.
1111         * get_targ.adb: Likewise.

1116         parameter and rename to...
1117         (In_RCI_Visible_Declarations): Fix handling of private part of nested
1118         package.
1119         (Validate_RCI_Subprogram_Declaration): Reject illegal function
1120         returning anonymous access in RCI unit.
1121
1122 2015-01-06  Ed Schonberg  <schonberg@adacore.com>
1123
1124         * sem_ch6.adb (New_Overloaded_Entity): In GNATprove mode, a
1125         function wrapper may be a homonym of another local declaration.
1126         * sem_ch8.adb (Analyze_Subprogram_Renaming): In GNATprove mode,
1127         build function and operator wrappers after the actual subprogram
1128         has been resolved, and replace the standard renaming declaration
1129         with the declaration of wrapper.
1130         * sem_ch12.ads (Build_Function_Wrapper, Build_Operator_Wraooer):
1131         make public for use elsewhere.
1132         * sem_ch12.adb (Build_Function_Wrapper, Build_Operator_Wraooer):
1133         rewrite, now that actual is fully resolved when wrapper is
1134         constructed.

1158         others choice that covers multiple components, analyze each
1159         copy with the type of the component even in compile-only mode,
1160         to detect potential accessibility errors.

1165         (Resolve_Actuals): An effectively volatile out
1166         parameter cannot act as an in or in out actual in a call.
