/*
 *  This header file provides macros used to construct, identify and use
 *  "target numbers" that are assigned to various types of Xtensa processor
 *  registers and states.  These target numbers are used by GDB in the remote
 *  protocol, and are thus used by all GDB debugger agents (targets).
 *  They are also used in ELF debugger information sections (stabs, dwarf, etc).
 *
 *  These macros are separated from xtensa-libdb.h because they are needed
 *  by certain debugger agents that do not use or have access to libdb,
 *  e.g. the OCD daemon, RedBoot, XMON, etc.
 *
 *  For the time being, for compatibility with certain 3rd party debugger
 *  software vendors, target numbers are limited to 16 bits.  It is
 *  conceivable that this will be extended in the future to 32 bits.
