* jv-exp.y (push_fieldnames): New, to handle EXP.FIELD1....FIELDN.
(push_expression_name): New, to handle expression names. (push_qualified_expression_name): New, for qualified expression names. (parse_number): Fix bugs in parsing of non-decimal integers. * jv-lang.h, jv-lang.c (java_demangle_type_signature): New. * jv-lang.c (type_from_class): Just use name with java_lookup_class. (java_link_class_type): Add dummy "class" field. (java_lookup_type): New. (evaluate_subexp_java case STRUCTOP_STRUCT): Force to address. * jv-typeprint.c (java_type_print_base): Don't print "class" field. Use java_demangle_type_signature to print array class types. * jv-valprint.c (java_value_print): Preliminary array support. Print pointer as TYPE@HEXADDR, instead of (TYPE)0xHEXADDR. (java_val_print): Move check for object type to java_value_print. Check for null. Print pointer as @HEXADDR, not 0xHEXADDR.
