* m32c.opc (parse_unsigned_bitbase): Take a new parameter which
decides if this function accepts symbolic constants or not. (parse_signed_bitbase): Likewise. (parse_unsigned_bitbase8): Pass the new parameter. (parse_unsigned_bitbase11): Likewise. (parse_unsigned_bitbase16): Likewise. (parse_unsigned_bitbase19): Likewise. (parse_unsigned_bitbase27): Likewise. (parse_signed_bitbase8): Likewise. (parse_signed_bitbase11): Likewise. (parse_signed_bitbase19): Likewise. * m32c-asm.c: Regenerate.
