11# DESCRIPTION
12#
13# This file can be used with the following setting:
14#   plugin.process.gdb-remote.target-definition-file
15# This setting should be used when you are trying to connect to a
16# remote GDB server that doesn't support any of the register discovery
17# packets that LLDB normally uses.
18#
19# Why is this necessary? LLDB doesn't require a new build of LLDB that
20# targets each new architecture you will debug with. Instead, all
21# architectures are supported and LLDB relies on extra GDB server
22# packets to discover the target we are connecting to so that is can
23# show the right registers for each target. This allows the remote stub
24# to change and add new registers without requiring a new LLDB build
25# just so we can see new registers.
26#
27# This file implements the x86_64 registers for the user mode qemu on linux.
28# The only difference with the Linux file is the absense of orig_rax register.
29#
30# USAGE
31#
32# (lldb) settings set plugin.process.gdb-remote.target-definition-file /path/to/x86_64_qemu_target_definition.py
33# (lldb) gdb-remote other.baz.com:1234
34#
35# The target definition file will get used if and only if the
36# qRegisterInfo packets are not supported when connecting to a remote
37# GDB stub.
