2007-08-14 Ed Schonberg <schonberg@adacore.com> Javier Miranda <miranda@adacore.com> * exp_disp.ads, exp_disp.adb (Build_Dispatch_Tables): Handle tagged types declared in the declarative part of a nested package body or in the proper body of a stub. (Set_All_DT_Position): Add missing check to avoid wrong assignation of the same dispatch table slot to renamed primitives. (Make_Select_Specific_Data_Table): Handle private types. (Tagged_Kind): Handle private types. (Make_Tags, Make_DT): Set tag entity as internal to ensure proper dg output of implicit importation and exportation. (Expand_Interface_Thunk): Fix bug in the expansion assuming that the first formal of the thunk is always associated with the controlling type. In addition perform the following code cleanup: remove formal Thunk_Alias which is no longer required, cleanup evaluation of the the controlling type, and update the documentation. Replace occurrence of Default_Prim_Op_Count by Max_Predef_Prims. Addition of compile-time check to verify that the value of Max_Predef_Prims is correct. (Check_Premature_Freezing): Apply check in Ada95 mode as well. (Make_DT): Add parameter to indicate when type has been frozen by an object declaration, for diagnostic purposes. (Build_Static_Dispatch_Tables): New subprogram that takes care of the construction of statically allocated dispatch tables. (Make_DT): In case of library-level tagged types export the declaration of the primary tag. Remove generation of tags (now done by Make_Tags). Additional modifications to handle non-static generation of dispatch tables. Take care of building tables for asynchronous interface types (Make_Tags): New subprogram that generates the entities associated with the primary and secondary tags of Typ and fills the contents of Access_ Disp_Table. In case of library-level tagged types imports the forward declaration of the primary tag that will be declared later by Make_DT. (Expand_Interface_Conversion): In case of access types to interfaces replace an itype declaration by an explicit type declaration to avoid problems associated with the scope of such itype in transient blocks.
