  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.
