* vax-tdep.h: Update copyright year. Adjust comments.
(VAX_REGISTER_SIZE, VAX_REGISTER_BYTES, VAX_MAX_REGISTER_RAW_SIZE, VAX_MAX_REGISTER_VIRTUAL_SIZE): Remove macros. (vax_regnum): New enum. Replacing... (VAX_AP_REGNUM, VAX_FP_REGNUM, VAX_SP_REGNUM, VAX_PC_REGNUM) (VAX_PS_REGNUM): ... these removed macros. * vax-tdep.c (vax_register_name): Remove prototype. (vax_register_name): Reorganize somewhat. Use ARRAY_SIZE. (vax_register_byte, vax_register_raw_size, vax_register_virtual_size, vax_register_virtual_type): Remove functions. (vax_register_type): New function. (vax_breakpoint_from_pc): Reorganize. (vax_gdbarch_init): Set register_type. Don't set deprecated_register_size, deprecated_register_bytes, deprecated_register_byte, deprecated_register_raw_size, deprecated_max_register_raw_size, deprecated_register_virtual_size, deprecated_max_register_virtual_size and deprecated_register_virtual_type. Add comment on stack direction.
