1071
1072         * set_targ.ads (C_Type_For): New function. Return the name of
1073         a C type supported by the back-end and suitable as a basis to
1074         construct the standard Ada floating point type identified by
1075         the T parameter. This is used as a common ground to feed both
1076         ttypes values and the GNAT tree nodes for the standard floating
1077         point types.
1078         * set_targ.adb (Long_Double_Index): The index at which "long
1079         double" gets registered in the FPT_Mode_Table. This is useful to
1080         know whether we have a "long double" available at all and get at
1081         it's characteristics without having to search the FPT_Mode_Table
1082         when we need to decide which C type should be used as the
1083         basis for Long_Long_Float in Ada.
1084         (Register_Float_Type): Fill Long_Double_Index.
1085         (FPT_Mode_Index_For): New function. Return the index in
1086         FPT_Mode_Table that designates the entry corresponding to the
1087         provided C type name.
1088         (FPT_Mode_Index_For): New function. Return the index in
1089         FPT_Mode_Table that designates the entry for a back-end type
1090         suitable as a basis to construct the standard Ada floating point
1091         type identified by the input T parameter.
1092         (elaboration code): Register_Back_End_Types unconditionally,
1093         so C_Type_For can operate regardless of -gnateT. Do it
1094         early so we can query it for the floating point sizes, via
1095         FPT_Mode_Index_For. Initialize Float_Size, Double_Size and
1096         Long_Double_Size from the FPT_Mode_Table, as cstand will do.
1097         * cstand.adb (Create_Float_Types): Use C_Type_For to determine
1098         which C type should be used as the basis for the construction
1099         of the Standard Ada floating point types.
1100         * get_targ.ads (Get_Float_Size, Get_Double_Size,
1101         Get_Long_Double_Size): Remove.
1102         * get_targ.adb: Likewise.
1103

1107         parameter and rename to...
1108         (In_RCI_Visible_Declarations): Fix handling of private part of nested
1109         package.
1110         (Validate_RCI_Subprogram_Declaration): Reject illegal function
1111         returning anonymous access in RCI unit.
1112
1113 2015-01-06  Ed Schonberg  <schonberg@adacore.com>
1114
1115         * sem_ch6.adb (New_Overloaded_Entity): In GNATprove mode, a
1116         function wrapper may be a homonym of another local declaration.
1117         * sem_ch8.adb (Analyze_Subprogram_Renaming): In GNATprove mode,
1118         build function and operator wrappers after the actual subprogram
1119         has been resolved, and replace the standard renaming declaration
1120         with the declaration of wrapper.
1121         * sem_ch12.ads (Build_Function_Wrapper, Build_Operator_Wraooer):
1122         make public for use elsewhere.
1123         * sem_ch12.adb (Build_Function_Wrapper, Build_Operator_Wraooer):
1124         rewrite, now that actual is fully resolved when wrapper is
1125         constructed.
1126

1149         others choice that covers multiple components, analyze each
1150         copy with the type of the component even in compile-only mode,
1151         to detect potential accessibility errors.
1152
1153 2015-01-06  Hristian Kirtchev  <kirtchev@adacore.com>
1154
1155         * sem_res.adb (Is_Assignment_Or_Object_Expression): New routine.
1156         (Resolve_Actuals): An effectively volatile out
1157         parameter cannot act as an in or in out actual in a call.
1158         (Resolve_Entity_Name): An effectively volatile out parameter
1159         cannot be read.

1178         in two different project tree is checked in both trees, if they
1179         are sources of two different projects, extended or not.
