	libjava        : ChangeLog 

Log message:
	gcc/java:
	
	* java-tree.h (otable_methods, otable_decl, otable_syms_decl,
	otable_type, otable_ptr_type, method_symbol_type,
	method_symbols_array_type, method_symbols_array_ptr_type): New
	field/global tree definitions.
	(flag_indirect_dispatch): New flag.
	* decl.c (java_init_decl_processing): Initialize new otable and
	otable_syms type nodes and decls. Add new field "index" to
	method_type_node.
	* class.c (build_method_symbols_entry): New function.
	(make_method_value): Set "index" to to method's vtable index for
	virtual methods when indirect-dispatch is not used.
	(make_class_data): For indirect-dispatch, dont emit the dtable_decl,
	and set vtable_method_count to -1. Set otable and otable_syms field
	if indirect-dispatch is used and there was something to put in them.
	(build_method_symbols_entry): New function.
	(emit_offset_symbol_table): New function.
	* expr.c (get_offset_table_index): New function.
	(build_invokevirtual): Build array reference to otable at the index
	returned by get_offset_table_index, and use the result as the vtable
	offset.
	(build_invokeinterface): Similar.
	* jcf-parse.c (yyparse): If indirect-dispatch, call
	emit_offset_symbol_table at the end of compilation, after all classes
	have been generated.
	* jvspec.c: Don't pass findirect-dispatch to jvgenmain.
	* lang.c (flag_indirect_dispatch): Define.
	(lang_f_options): Add indirect-dispatch flag.
	
	libjava:
	
	* include/jvm.h (_Jv_VTable::idx_to_offset): New method.
	* java/lang/natClassLoader.cc (_Jv_PrepareCompiledClass): Call
	_Jv_MakeVTable and _Jv_LinkOffsetTable if needed.
	* java/lang/Class.h (_Jv_Method): Add "index" field.
	(_Jv_MethodSymbol): New struct type.
	(_Jv_LinkOffsetTable, _Jv_LayoutVTableMethods, _Jv_SetVTableEntries,
	_Jv_MakeVTable): Friends.
	(otable, otable_syms): New Class fields.
	* java/lang/natClass.cc (_Jv_LinkOffsetTable): New function.
	(isVirtualMethod): New static function.
	(_Jv_LayoutVTableMethods): New function.
	(_Jv_SetVTableEntries): New function.
	(_Jv_MakeVTable): New function.
