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_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.
