More cleanup on the lldb-perf code: 

- TestCase.m_thread is now filled in with the first thread that has a valid
  stop reason. This eliminates the need for the SelectMyThread() functions.
- The first thread that stops for a reason is also set as the selected thread
  in the process in case any command line commands are run.
- Changed launch over to take a SBLaunchInfo parameter so that the launch
  function doesn't keep getting new arguments as they are needed.
- TestCase::Setup() and TestCase::Launch(SBLaunchInfo) now return bool to 
  indicate success of setup and launch.
- ActionWanted::Next(SBThread) was renamed to ActionWanted::StepOver(SBThread)
- ActionWanted::Finish(SBThread) was renamed to ActionWanted::StepOut(SBThread)

The lldb-perf infrastructure for LLDB performance testing

lldb-perf is an infrastructure meant to simplify the creation of performance
tests for the LLDB debugger. It is contained in liblldbperf.a which is part of
the standard opensource checkout of LLDB
Its main concepts are:
- Gauges: a gauge is a thing that takes a sample (e.g. it samples the time elapsed, the memory used, the energy consumed)
- Metrics: a metric is a collection of samples that knows how to do statistics (for now, sum() and average() but can be extended as need be)
- Measurements: a measurement is the thing that stores an action, a gauge and a metric. essentially, you define measurements as in “take the time to run this function”, “take the memory to run this block of code”, and then after you invoke it, your stats will be automagically there
- Tests: a test is a sequence of steps and measurements
- Gauges: a gauge is a thing that takes a sample. Samples include elapsed time,
memory used, and energy consumed.

like sum() and average(). Metrics can be extended as needed.

“take the memory to run this block of code”, and then after you invoke it,
your stats will automagically be there.
- Tests: a test is a sequence of steps and measurements.
Tests cases should be added as targets to the lldbperf.xcodeproj project. It is probably easiest to duplicate one of the existing targets.
In order to write a test based on lldb-perf, you need to subclass lldb_perf::TestCase, as in:

A TimeMeasurement is, obviously, a class that measures “how much time to run this block of code”. the block of code is passed as an std::function (you can construct with a lambda!) - you need however to give the prototype of your block of code. in this example, we run blocks of code that take an SBValue and return nothing. other things are possible.
These blocks look like:
m_dump_std_vector_measurement = CreateTimeMeasurement([] (SBValue value) -> void {
lldb_perf::Xcode::FetchVariable (value,1,false);
}, "std-vector", "time to dump an std::vector");
Here we are saying: make me a measurement named “std-vector”, whose description is “time to dump an std::vector” and that takes the time required to call lldb_perf::Xcode::FetchVariable(value,1,false)

Once your test case is constructed, Setup() is called on it:
virtual void
virtual bool
Setup (int argc, const char** argv)
{
m_app_path.assign(argv[1]);
m_out_path.assign(argv[2]);
m_target = m_debugger.CreateTarget(m_app_path.c_str());
m_target.BreakpointCreateByName("main");
Launch (NULL,".");
SBLaunchInfo launch_info (argv);
return Launch (launch_info);
}
(I am considering moving Setup to the constructor, to be honest, but have not done so yet because it might also make sense to have Setup() return a bool or an Error object. stay tuned for more here!)
In Setup() you process command-line arguments and create a target to run
Setup() returns a boolean value that indicates if setup was successful.
In Setup() you fill out a SBLaunchInfo with any needed settings for launching
your process like arguments, environment variables, working directory, and
much more.
The last thing you want to do in setup is call Launch():
bool
Launch (const char** args, const char* cwd);
This ensures your target is now alive. Make sure to have a breakpoint created :)
Once you launched, the event loop is entered. The event loop waits for stops, and when it gets one, it calls your test case’s
Launch (coSBLaunchInfo &launch_info);
This ensures your target is now alive. Make sure to have a breakpoint created.
Once you launched, the event loop is entered. The event loop waits for stops,
and when it gets one, it calls your test case’s TestStep() function:
virtual void
TestStep (int counter, ActionWanted &next_action)
the counter is the step id (a monotonically increasing counter). In TestStep() you will essentially run your measurements and then return what you want the driver to do.
Possible options are:
- continue process ActionWanted::Continue()
- kill process ActionWanted::Kill()
- finish on a thread ActionWanted::Finish(SBThread)
- step-over on a thread. ActionWanted::Next(SBThread)
the counter is the step id (a monotonically increasing counter). In TestStep()
you will essentially run your measurements and then return what you want the
driver to do by filling in the ActionWanted object named "next_action".
If you use ActionWanted::Next() or ActionWanted::Finish(), define a SelectMyThread() that gives you an SBThread. I usually use a filename as key:
SBThread
SelectMyThread (const char* file_name)
{
auto threads_count = m_process.GetNumThreads();
for (auto thread_num = 0; thread_num < threads_count; thread_num++)
{
SBThread thread(m_process.GetThreadAtIndex(thread_num));
auto local_file_name = thread.GetFrameAtIndex(0).GetCompileUnit().GetFileSpec().GetFilename();
if (!local_file_name)
continue;
if (strcmp(local_file_name,file_name))
continue;
return thread;
}
Xcode::RunCommand(m_debugger,"bt all",true);
assert(false);
}
you might want to use some other logic in your selection.
For your convenience TestCase has m_debugger, m_target and m_process as member variables. There is also an m_thread, but that is for you to set if you need/want to use it!
Possible options are:
- continue process next_action.Continue();
- kill process next_action.Kill();
- Step-out on a thread next_action.StepOut(SBThread)
- step-over on a thread. next_action.StepOver(SBThread)
If you use ActionWanted::Next() or ActionWanted::Finish() you need to specify
a thread to use. By default the TestCase class will select the first thread
that had a stop reason other than eStopReasonNone and place it into the
m_thread member variable of TestCase. This means if your test case hits a
breakpoint or steps, the thread that hit the breakpoint or finished the step
will automatically be selected in the process (m_process) and m_thread will
be set to this thread. If you have one or more threads that will stop with a
reason simultaneously, you will need to find those threads manually by
iterating through the process list and determine what to do next.
For your convenience TestCase has m_debugger, m_target and m_process as member
variables. As state above m_thread will be filled in with the first thread
that has a stop reason.

Your main() will look like:

If you are debugging your test, before Run() call
test.SetVerbose(true);
