2009-04-20 Javier Miranda <miranda@adacore.com> * einfo.ads, einfo.adb (Is_Underlying_Record_View): New subprogram (Set_Is_Underlying_Record_View): New subprogram * sem_aggr.adb (Discr_Present, Resolve_Record_Aggregate): In case of private types with unknown discriminants use the underlying record view if available. * sem_ch3.adb (Build_Derived_Private_Type): Enable construction of the underlying record view in the full view of private types whose parent has unknown discriminants. (Build_Derived_Record_Type): Avoid generating the class-wide entity associated with an underlying record view. (Derived_Type_Declaration): Avoid deriving parent primitives in underlying record views. * sem_ch6.adb (Check_Return_Subtype_Indication): Add support for records with unknown discriminants. * sem_type.adb (Covers): Handle underlying record views. (Is_Ancestor): Add support for underlying record views. * exp_attr.adb (Expand_Attribute): Expand attribute 'size into a dispatching call if the type of the target object is tagged and has unknown discriminants. * exp_aggr.adb (Resolve_Record_Aggregate): Add support for records with unknown discriminants. * exp_disp.adb (Build_Dispatch_Tables): Avoid generating dispatch tables for internally built underlying record views. * sprint.adb (sprint_node_actual): Improve output of aggregates with an empty list of component associations. 2009-04-20 Thomas Quinot <quinot@adacore.com> * sem_ch10.adb: Minor reformatting * socket.c, g-socthi-vms.adb, g-socthi-vms.ads, g-socthi-vxworks.ads, g-socthi-mingw.ads, g-socthi.ads, g-socket.adb (GNAT.Sockets.Inet_Addr): Do not use non-portable inet_aton, instead use standard inet_pton API (and emulate it on platforms that do not support it). (GNAT.Sockets.Thin.Inet_Pton, VMS case): Implement in terms of DECC$INET_ADDR, imported in Ada. (GNAT.Sockets.Thin.Inet_Pton, VxWorks and Windows cases): Use C implementation provided by GNAT runtime. (__gnat_inet_pton): C implementation of inet_pton(3) for VxWorks and Windows.
