+# All about Air.js
+
+Air.js is an ES6 benchmark. It tries to faithfully use new features like arrow
+functions, classes, for-of, and Map/Set, among others. Air.js doesn't avoid any
+features out of fear that they might be slow, in the hope that we might learn
+how to make those features fast by looking at how Air.js and other benchmarks
+use them.
+
+This documents the motivation, design, and license of Air.js.
+
+To run Air.js, simply open "[Air.js/test.html](test.html)" in your browser. It
+will only run correctly if your browser supports ES6.
+
+## Motivation
+
+At the time that Air.js was written, most JavaScript benchmarks used ES5 or
+older versions of the language. ES6 testing mostly relied on microbenchmarks or
+conversions of existing tests to ES6. We try to use larger benchmarks to avoid
+over-optimizing for small pieces of code, and we avoid making changes to
+existing benchmarks because that approach has no limiting principle: if it's OK
+to change a benchmark to use a feature, does that mean we can also change it to
+remove the use of a feature we don't like? We feel that the best way to avoid
+falling into the trap of creating benchmarks that reinforce what some JS engine
+is already good at is to create a new benchmark from first principles.
+
+We only recently completed our new JavaScript compiler, called
+[B3](https://webkit.org/blog/5852/introducing-the-b3-jit-compiler/). B3's
+backend, called
+[Air](https://webkit.org/docs/b3/assembly-intermediate-representation.html), is
+very CPU-intensive and uses a combination of object-oriented and functional
+idioms in C++. Additionally, it relies heavily on high speed maps and sets. It
+goes so far as to use customized map/set implementations - even more so than
+the rest of WebKit. This makes Air a great candidate for ES6 benchmarking.
+Air.js is a faithful ES6 implementation of Air. It pulls no punches: just as
+the original C++ Air was written with expressiveness as a top priority, Air.js
+is liberal in its use of modern ES6 idioms whenever this helps make the code
+more readable. Unlike the original C++ Air, Air.js doesn't exploit a deep
+understanding of compilers to make the code easy to compile.
+
+## Design
+
+Air.js runs one of the more expensive Air phases, Air::allocateStack(). This
+turns abstract stack references into concrete stack references, by selecting
+how to lay out stack slots in the stack frame. This requires liveness analysis
+and an interference graph.
+
+Air.js relies on three major ES6 features more so than most of the others:
+
+- Arrow functions. Like the C++ Air, Air.js uses a functional style of
+  iterating most non-trivial data-structures:
+
+        inst.forEachArg((arg, role, type, width) => ...)
+  
+  This is because the functional style allows the callbacks to mutate the data
+  being iterated: if the callback returns a non-null value, forEachArg() will
+  replace the argument with that value. This would not have been possible with
+  for-of.
+
+- For-of. Many Air data structures are amenable to for-of iteration. While the
+  innermost loops tend to use functional iteration, pretty much all of the
+  outer logic uses for-of heavily. For example:
+
+        for (let block of code) // Iterate over the basic blocks
+            for (let inst of block) // Iterate over the instructions in a block
+                ...
+
+- Map/Set. The liveness analysis and Air::allocateStack() rely on maps and
+  sets. For example, we use a liveAtHead map that is keyed by basic block. Its
+  values are sets of live stack slots. This is a relatively crude way of doing
+  liveness, but it is exactly how the original Air::LivenessAnalysis worked, so
+  we view it as being quite faithful to how a sensible programmer might use Map
+  and Set.
+
+Air.js also uses some other ES6 features. For example, it uses a Proxy
+in one place, though we doubt that it's on a critical path. Air.js uses classes
+and let/const extensively, as well a symbols. Symbols are used as enumeration
+elements, and so they frequently show up as cases in switch statements.
+
+The workflow of an Air.js run is pretty simple: we do 150 runs of allocateStack
+on four IR payloads.
+
+Each IR payload is a large piece of ES6 code that constructs an Air.js Code
+object, complete with blocks, temporaries, stack slots, and instructions. These
+payloads are generated by running Air::dumpAsJS() phase just prior to the
+native allocateStack phase on the largest hot function in four major JS
+benchmarks according to JavaScriptCore's internal profiling:
+
+- Octane/GBEmu, the executeIteration function.
+- Kraken/imaging-gaussian-blur, the gaussianBlur function.
+- Octane/Typescript, the scanIdentifier function,
+- Air.js, an anonymous closure identified by our profiler as ACLj8C.
+
+These payloads allow Air.js to precisely replay allocateStack on those actual
+functions.
+
+It was an a priori goal of Air.js to spend most of the time in the
+allocateStack phase. This is a faithful reproduction of the C++ allocateStack
+phase, including its use of an abstract liveness analysis. It's abstract in the
+sense that the same liveness algorithm can be reused for temporaries,
+registers, or stack slots. In C++ this meant using templates, while in ES6 it
+means more run-time dynamic dispatch.
+
+Each IR payload is executable code that allocates the IR, and about 15% of
+benchmark execution time is spent in that code. This is significant, but having
+learned this, we don't feel that it would be honest to try to change the
+efficiency of payload initialization. What if the payload initialization was
+more expensive on our engine than others? If it was, then such a change would
+not be fair.
+
+Air.js validates its results. We added a Code hashing capability to both the
+C++ Air and Air.js, and we assert each payload looks identical after
+allocateStack to what it would have looked like after the original C++
+allocateStack. We also validate that payloads hash properly before
+allcoateStack, to help catch bugs during payload initialization. We have not
+measured how long hashing takes, but it's a O(N) operation, while allocateStack
+is closer to O(N^2). We suspect that barring some engine pathologies, hashing
+should be much faster than allocateStack, and allocateStack should be where the
+bulk of time is spent.

+## Summary
+
+At the time that Air.js was written, we weren't happy with the ES6 benchmarks
+that were available to us. Air.js uses some ES6 features in anger, in the hope
+that we can learn about possible optimization strategies by looking at this and
+other benchmarks.

+    
+        <h2>About the Tests</h2>
+        
+        <p>ARES-6 measures the execution time of JavaScript&#8217;s newest features, including symbols, for-of, arrow functions, Map/Set/WeakMap, let/const, classes, proxies, string interpolation, destructuring, default arguments, spread, tail calls, and generators. ARES-6 is comprised of four sub-tests: Air, Basic, Babylon, and ML.</p>
+
+        <p>Air is an ES2015 port of the <a href="https://webkit.org/blog/5852/introducing-the-b3-jit-compiler/">WebKit B3 JIT</a>&#8217;s <a href="https://trac.webkit.org/changeset/201783"><code>Air::allocateStack</code> phase</a>. This code is a heavy user of Map, Set, classes, spread, and for-of. The benchmark runs <code>allocateStack</code> on hot function bodies from other popular JavaScript benchmarks: <code>executeIteration</code> from <a href="https://developers.google.com/octane/">Octane</a>/Gameboy, <code>gaussianBlur</code> from <a href="http://krakenbenchmark.mozilla.org">Kraken</a>, and <code>scanIdentifier</code> from Octane/Typescript. Air also runs <code>allocateStack</code> on a hot function from Air itself. <a href="https://trac.webkit.org/browser/trunk/PerformanceTests/ARES-6/Air?rev=211697">Browse the source.</a></p>
+
+        <p>Basic is an <a href="https://trac.webkit.org/changeset/202446">ES2015 implementation</a> of the <a href="http://www.ecma-international.org/publications/files/ECMA-ST-WITHDRAWN/ECMA-55,%201st%20Edition,%20January%201978.pdf">ECMA-55 BASIC standard</a>. BASIC was an interactive language from the start, so our implementation uses generator functions for the entire interpreter. When the BASIC program says <code>INPUT</code>, our interpreter says <code>yield</code>. This allows users of the interpreter to easily integrate it into a runloop. Basic also uses classes, Map, and WeakMap. The benchmark runs a handful of simple programs, the most complex of which finds prime numbers. <a href="https://trac.webkit.org/browser/trunk/PerformanceTests/ARES-6/Basic?rev=211697&order=name">Browse the source.</a></p>
+
+        <p>
+           <a href="https://github.com/babel/babylon">Babylon</a> is an implementation of a parser for the JavaScript language.
+           Babylon is the parser used in the <a href="https://babeljs.io">Babel</a> JavaScript transpiler.
+           The benchmark runs the Babylon parser on four different JavaScript sources. Babylon makes heavy use of classes,
+           does non trivial string processing, and creates non-trivial object graphs.
+        </p>
+
+        <p>
+            <a href="https://github.com/mljs/feedforward-neural-networks">ML</a> is an implementation of a <a href="https://en.wikipedia.org/wiki/Feedforward_neural_network"> feedforward neural network</a>.
+            The benchmark trains several networks using different <a href="https://en.wikipedia.org/wiki/Activation_function">activation functions</a>
+            and several sample data sets. ML makes heavy use of classes. It relies on the <a href="https://github.com/mljs/matrix">ml-matrix</a> library
+            and does non-trivial matrix math.
+        </p>
+
+        <p>ARES-6 rewards browsers that start up quickly and run smoothly. It's not enough to just measure the total running time of a workload. Browsers may perform differently for the same workload depending on how many times it has run. Garbage collection runs periodically, making some iterations take longer than others. Code that runs repeatedly gets optimized by the browser, so the first iteration of any workload is more expensive than the rest. ARES-6 runs Air, Basic, and Babylon for 200 iterations, and ML for 60 iterations. For each benchmark, ARES-6 reports the time of the first iteration, the average of the 4 worst iterations, and the average of all but the first iteration. ARES-6 also reports an overall score which is the geometric mean of all twelve of these numbers. ARES-6 equally rewards fast start-up, low jank, and sophisticated adaptive optimizations for long-running code.</p>
+        
+        <p>Each ARES-6 sample has 200 iterations of Air, Basic, and Babylon, and 60 iterations of ML. ARES-6 runs 6 samples, and reports the average with 95% confidence intervals. Each sample runs in a fresh <code>iframe</code> to simulate some of the effects of page navigation.</p>
