            Bug ID: 27326
           Summary: Provide a way to exit lldb with a non-zero exit status
           Product: lldb
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: All Bugs
          Assignee: lldb-dev at lists.llvm.org
          Reporter: john.firebaugh at gmail.com

    Classification: Unclassified

Please provide a way to exit scripted lldb interactions with a non-zero exit
status. This is necessary for, e.g. running a debugged program in an automated
test environment, and printing diagnostics and then exiting with a non-zero
exit status if a crash occurs.

This could take several forms:

* An equivalent of GDB's "-return-child-result" option.
* An argument form of "quit", e.g. "quit 1". (GDB also supports this.)

For instance, I would like the following command to work as expected:

  lldb --batch -o 'run' -k 'thread backtrace all' -k 'quit 1' <program>
