Hi all,
I have just synced up to the top-of-tree for llvm, clang and lldb, and
rebuilt for 64-bit linux. I've found that the implementation of the
command "gdb-remote localhost:<port>", is now broken
./lldb ~/src/play/c/simp/simp-x64
Traceback (most recent call last):
File "<string>", line 1, in <module>
ImportError: No module named lldb.embedded_interpreter
Current executable set to '/home/mg11/src/play/c/simp/simp-x64' (x86_64).
(lldb) gdb-remote localhost:7778
Process 0 connected
error: Process 0 is currently being debugged, kill the process before
connecting.
(lldb) bt
error: invalid thread
It seems the client-side is not collecting the process and thread
information correctly from the server. The GDB-RSP (server=7778) is as
follows:

This functionality was working (almost) properly about a month ago. Here
is a run using that binary and a trace.

Part of the problem, it seems, is that the new build does not send "qC"
(get current thread id).
Is there anyone currently working in this area? Or is it a bug I should
start to look at?
thanks
