Subject: [PATCH] Report exit status message in lldb-dap, same as lldb cli
Summary:
When the target inferior process that is being debugged exits in lldb command
line, it emits following message:
Process 4049526 exited with status = -1 (0xffffffff) debugserver died with
signal SIGTERM
lldb-dap on the other hand does not emit a similar message.
This PR adds the same status message to lldb-dap.
Test Plan:
In VSCode debug any target and hit stop mode, kill lldb-server and observe an
exit status message similar to the following:
Process 2167677 exited with status = -1 (0xffffffff) debugserver died with
signal SIGTERM
