This is a first pass at removing some lldb-mi tests which have been xfailed and unmaintained for a while. We have open PRs for most of these tests already. I've opened up the following additional PRs: llvm.org/PR36739 - lldb-mi driver exits properly llvm.org/PR36740 - lldb-mi -gdb-set and -gdb-show llvm.org/PR36741 - lldb-mi -symbol-xxx The motivation here is to address timeout and pexpect-related issues in the test suite. This was discussed on lldb-dev in the thread: "increase timeout for tests?". After this change, the lldb-mi tests seem to be in better health (on Darwin at least). I consistently get: $ ./bin/llvm-dotest -p TestMi =================== Test Result Summary =================== Test Methods: 101 Reruns: 0 Success: 88 Expected Failure: 0 Failure: 0 Error: 0 Exceptional Exit: 0 Unexpected Success: 0 Skip: 13 Timeout: 0 Expected Timeout: 0 llvm-svn: 327552
