As discussed offline, this tool is no longer used or maintained, and
doesn't provide the right abstraction for performance tracking in lldb.

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

*** to conform to clang-format’s LLVM style. This kind of mass change has
*** two obvious implications:
Firstly, merging this particular commit into a downstream fork may be a huge
effort. Alternatively, it may be worth merging all changes up to this commit,
performing the same reformatting operation locally, and then discarding the
merge for this particular commit. The commands used to accomplish this
reformatting were as follows (with current working directory as the root of
the repository):
find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} +
find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ;
The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.
Secondly, “blame” style tools will generally point to this commit instead of
a meaningful prior commit. There are alternatives available that will attempt
to look through this change and find the appropriate prior commit. YMMV.

- Added new abtract Results class to keep CoreFoundation out of the tests. There are many subclasses for different settings:
Results::Result::Dictionary
Results::Result::Array
Results::Result::Unsigned
Results::Result::Double
Results::Result::String
- 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

- 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

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">

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.
