* ch-lang.c (chill_is_varying_struct), ch-lang.h: New function. * ch-lang.c (chill_printstr): Use double quotes, not single quotes. * ch-typeprint.c (chill_type_print_base): Handle TYPE_CODE_BITSTRING. Improve printing of TYPE_CODE_STRING, TYPE_CODE_SET, and TYPE_CODE_STRUCT (including checking chill_is_varying_struct). Print TYPE_DUMMY_RANGE by printing its TYPE_TARGET_TYPE. Handle TYPE_CODE_ENUM. * ch-valprint.c (chill_val_print): Handle TYPE_CODE_BITSTRING. For TYPE_CODE_STRING, never print address. Handle VARYING strings. * gdbtypes.c (force_to_range_type): New. * gdbtypes.c (create_set_type): Make work, following Chill layout. * gdbtypes.h (TYPE_LOW_BOUND, TYPE_HIGH_BOUND, TYPE_DUMMY_RANGE): New. * stabsread.c (read_type): Distinguish string and bitstring from char-array and set. * valarith.c (value_subscript), valops.c (value_coerce_array): Handle STRINGs as well as ARRAYs. * valarith.c (value_bit_index): Fix think. Use new macros.
