It contains IMPORTANT +INFORMATION for BE writers who wish to migrate a BE written to operate with +release 1.2 to operate with release 1.3. It is likely that not following +these instructions will result in a compilable but malfunctioning compiler. + +AST INHERITANCE CHANGES + +The AST has been reorganized so that AST_Union and AST_Exception now +inherit from AST_Structure. This means that constructors of BE classes +which inherit from AST_Union or AST_Exception now need to explicitly call +an initializer for AST_Structure in their init section. + +We repeat below the information given in the file WRITING_A_BE, in the +section entitled "WRITING A BE". + +AST_EXCEPTION + +The signature for constructors of classes inheriting from AST_Exception +should now be: + + BE_Exception::BE_Exception(UTL_ScopedName *n, + UTL_StrList *p) + : AST_Decl(AST_Decl::NT_except, n, p), + AST_Structure(AST_Decl::NT_except, n, p), + UTL_Scope(AST_Decl::NT_except) + +AST_UNION + +The signature for constructors of classes inheriting from AST_Union should +now be: + + BE_Union::BE_Union(AST_ConcreteType *dt, + UTL_ScopedName *n, + UTL_StrList *p) + : AST_Union(dt, n, p), + AST_Structure(AST_Decl::NT_union, n, p), + AST_Decl(AST_Decl::NT_union, n, p), + UTL_Scope(AST_Decl::NT_union) + +IDL_BOOL TYPE + +To increase portability and reduce dependency of the sources on POSIX +compliance in targets of ports, IDL now provides its own boolean type which +is named idl_bool. It provides two truth values, I_TRUE and I_FALSE. + +UTL_SCOPEDNAME TYPE + +The UTL_ScopedName type is now a list of Identifier nodes; in previous +releases it used to be a list of String nodes. If your BE constructs scoped +names this change will prevent recompilation until you modify your +constructor calls to invoke constructors for Identifier instead of for +String. The signature of the constructor is: + + Identifier::Identifier(char *, long x=1, long y=0, long z=I_FALSE) + +The additional arguments which can be defaulted to the values indicated are +included for future use. + +COPYRIGHT + +Copyright 1992, 1993, 1994 Sun Microsystems, Inc.
