9de4dec874148d30cc1d4c498d38cd048a8164ca 22-Mar-2013 Greg Clayton <gclayton@apple.com> Much more cleanup on the performance testing infrastructure:
- Added new abtract Results class to keep CoreFoundation out of the tests. There are many subclasses for different settings:
- Gauge<T> can now write themselves out via a templatized write to results function:
template <class T>
Results::ResultSP GetResult (const char *description, T value);

- There are four specializations of this so far:
template <>
Results::ResultSP GetResult (const char *description, double value);

template <>
Results::ResultSP GetResult (const char *description, uint64_t value);

template <>
Results::ResultSP GetResult (const char *description, std::string value);

template <>
Results::ResultSP GetResult (const char *description, MemoryStats value);
- Don't emit the virtual memory reading from the task info call as it really doesn't mean much as it includes way too much (shared cache + other stuff we don't have control over)
- Fixed other test cases to build correctly and use the new classes

af222500aa2ce2b18149277e561cdf75f2115df2 18-Mar-2013 Greg Clayton <gclayton@apple.com> Code cleanup:
- don't use preprocessor macros
- use switch statements
- don't put anything in the lldb namespace, use "lldb_perf" namespace.
- Pass the action struct into each TestStep() for each step fill in
- Modify the ActionWanted class to have accessors to make the continue, next, finish, kill instead of using preproc macros

f5af85a2946ed4e1ff4766829d328cfb4961f259 08-Mar-2013 Enrico Granata <egranata@apple.com> Initial checkin of a new project: LLDB Performance Testing Infrastructure

This is a very basic implementation of a library that easily allows to drive LLDB.framework to write test cases for performance

This is separate from the LLDB testsuite in test/ in that:
a) this uses C++ instead of Python to avoid measures being affected by SWIG
b) this is in very early development and needs lots of tweaking before it can be considered functionally complete
c) this is not meant to test correctness but to help catch performance regressions

There is a sample application built against the library (in darwin/sketch) that uses the famous sample app Sketch as an inferior to measure certain basic parameters of LLDB's behavior.
The resulting output is a PLIST much like the following:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">

Areas for improvement:
- code cleanups (I will be out of the office for a couple days this coming week, but please keep ideas coming!)
- more metrics and test cases
- better error checking

This toolkit also comprises a simple event-loop-driven controller for LLDB, similar yet much simpler to what the Driver does to implement the lldb command-line tool.
