# DESCRIPTION
#
# This file can be used with the following setting:
# plugin.process.gdb-remote.target-definition-file
# This setting should be used when you are trying to connect to a
# remote GDB server that doesn't support any of the register discovery
# packets that LLDB normally uses.
#
# Why is this necessary? LLDB doesn't require a new build of LLDB that
# targets each new architecture you will debug with. Instead, all
# architectures are supported and LLDB relies on extra GDB server
# packets to discover the target we are connecting to so that is can
# show the right registers for each target. This allows the GDB server
# to change and add new registers without requiring a new LLDB build
# just so we can see new registers.
#
# This file implements the x86_64 registers for the darwin version of
# GDB and allows you to connect to servers that use this register set.
#
# USAGE
#
# (lldb) settings set plugin.process.gdb-remote.target-definition-file /path/to/x86_64_linux_target_definition.py
# (lldb) gdb-remote other.baz.com:1234
#
# The target definition file will get used if and only if the
# qRegisterInfo packets are not supported when connecting to a remote
# GDB server.
