zturner added a comment.
One issue I can see with this is that if you check the documentation of -b it
says this:
-b
--batch
Tells the debugger to run the commands from -s, -S, -o & -O, and
then quit. However if any run command stopped due to a signal or
crash, the debugger will return to the interactive prompt at the
place of the crash.
So, this should work fine as long as none of these commands crash, but if they
do crash it will cause lit to hang. It might be useful to add a `-B` option to
LLDB that will *not* return to the interactive prompt in the case of a signal
or crash, and instead will just terminate. This way we'd see the crash as just
another form of test failure rather than a timeout.
