Andy Wingo wrote up a nice piece about the DFG optimizing compiler: http://wingolog.org/archives/2011/10/28/javascriptcore-the-webkit-js-implementation The code and design are in constant flux; the best way to really learn about it is to read the code. Here's the code for the DFG JIT: http://trac.webkit.org/browser/trunk/Source/JavaScriptCore/dfg Here's the code for the baseline JIT, which is used for fast start-up and profiling: http://trac.webkit.org/browser/trunk/Source/JavaScriptCore/jit Here are additional files that contain support for tiered compilation, profiling, and OSR: http://trac.webkit.org/browser/trunk/Source/JavaScriptCore/bytecode/CodeBlock.h http://trac.webkit.org/browser/trunk/Source/JavaScriptCore/bytecode/CodeBlock.cpp http://trac.webkit.org/browser/trunk/Source/JavaScriptCore/bytecode/CodeOrigin.h http://trac.webkit.org/browser/trunk/Source/JavaScriptCore/bytecode/PredictedType.h http://trac.webkit.org/browser/trunk/Source/JavaScriptCore/bytecode/PredictedType.cpp http://trac.webkit.org/browser/trunk/Source/JavaScriptCore/bytecode/ValueProfile.h http://trac.webkit.org/browser/trunk/Source/JavaScriptCore/bytecode/ValueProfile.cpp http://trac.webkit.org/browser/trunk/Source/JavaScriptCore/bytecode/ValueRecovery.h http://trac.webkit.org/browser/trunk/Source/JavaScriptCore/runtime/Executable.h http://trac.webkit.org/browser/trunk/Source/JavaScriptCore/runtime/Executable.cpp And finally some code to interface the optimizing JIT to the GC: http://trac.webkit.org/browser/trunk/Source/JavaScriptCore/heap/DFGCodeBlocks.h http://trac.webkit.org/browser/trunk/Source/JavaScriptCore/heap/DFGCodeBlocks.cpp -Filip _______________________________________________ webkit-dev mailing list webkit-dev@lists.webkit.org http://lists.webkit.org/mailman/listinfo.cgi/webkit-dev
