[lldb-dev] Increasing support for other gdbservers

[Aidan Dodds]

Hi Folks,

I would like to add better support for gdbserver from the gnu toolchain 
and similar legacy gdb stubs in lldb.
The work going into lldb-gdbserver is great but it is not always a 
possible to change the remote gdb stub, and there are so many tools and 
devices with older gdb stubs in them.

It seems like process gdb-remote has moved hand in hand with 
lldb-gdbserver away from gnu gdbservers RSP protocol.

Does anyone have an suggestions when it comes to adding lldb support for 
traditional gdbservers?

There seems like two obvious approaches; extend gdb-remote or create a 
gdb-legacy plugin.
To my mind the second approach may be cleaner, and a large amount of 
common code could be shared between the two.

Another approach would be to incorporate a plugin system into gdb-remote 
to ease the addition of new packets and handling routines.

I am interested to hear thoughts, suggestions and feedback on this topic.

Thanks,
Aidan
