UNOP_IND, UNOP_CAST, UNOP_ADDR, STRUCOP_STRUCT, OP_TYPE. * ch-typeprint.c (chill_print_type): Move support for TYPE_CODE_ARRAY and TYPE_CODE_STRING from here ... * ch-typeprint.c (chill_type_print_base): ... here. * ch-typeprint.c (chill_type_print_base): Improve support for PTR, REF, and FUNC types. * ch-valprint.c: Prefer H'%x format to 0x%s. * ch-valprint.c (chill_val_print): Add support for printing TYPE_CODE_REF (return for LOC parameters and variables). Use c_val_print to print random types (including ENUM). * ch-valprint,c (chill_print_value_fields): Make output look more like Chill tuples. * stabsread.c (read_struct_type): Factor common code.
