/*
|
|
* 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.
