V8 ネイティブ シンタックスを有効化する方法 [--allow-natives-syntax]
chrome の起動コマンドに以下のオプションを追加して起動する。
chrome で指定できる起動オプションの詳細は List of Chromium Command Line Switches « Peter Beverloo にある。
Linux
$ /opt/google/chrome/chrome --js-flags="--allow-natives-syntax" &
chrome-beta の Path: /opt/google/chrome-beta/chrome
Windows
> "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --js-flags="--allow-natives-syntax"
chrome-canary の Path: “%USERPROFILE%\AppData\Local\Google\Chrome SxS\Application\chrome.exe”
ネイティブ シンタックスを有効にすると、ブラウザーで以下の runtime.h に記載のある各組み込み関数が使用できるようになる。
https://cs.chromium.org/chromium/src/v8/src/runtime/runtime.h
例えば、%GetOptimizationStatus(func) 関数で V8 エンジンの JavaScript の最適化ステータスを取得することが出来る。
const printOptimizationStatus = (func) => { const wrapEval = (script) => { return (new Function(`"use strict"; return ${script};`))(); }; const isAllowNativeSyntax = () => { let native = false; try { wrapEval('%GetOptimizationStatus();'); native = true; } catch (err) { console.log('v8 engine is not running with --js-flags="--allow-natives-syntax";'); console.log('Native v8 functions are not available.'); native = false; } return native; }; const optStatusString = []; let funcName = ''; if (isAllowNativeSyntax()) { const checkBitmap = (value, bit) => { return ((value & bit) === bit); }; self._optCheckFunc = func; const optStatus = wrapEval('%GetOptimizationStatus(self._optCheckFunc);'); funcName = wrapEval('%GetFunctionName(self._optCheckFunc);'); if (checkBitmap(optStatus,1)) { optStatusString.push("is Function"); } if (checkBitmap(optStatus,2)) { optStatusString.push("Never Optimized"); } if (checkBitmap(optStatus,4)) { optStatusString.push("Always Optimized"); } if (checkBitmap(optStatus,8)) { optStatusString.push("Maybe Deopted"); } if (checkBitmap(optStatus,16)) { optStatusString.push("Optimized"); } if (checkBitmap(optStatus,32)) { optStatusString.push("TurboFanned"); } if (checkBitmap(optStatus,64)) { optStatusString.push("Interpreted"); } if (checkBitmap(optStatus,128)) { optStatusString.push("Marked for Optimization"); } if (checkBitmap(optStatus,256)) { optStatusString.push("Marked for Concurrent Optimization"); } if (checkBitmap(optStatus,512)) { optStatusString.push("Conccurently Optimizating"); } if (checkBitmap(optStatus,1024)) { optStatusString.push("Is Executing"); } if (checkBitmap(optStatus,2048)) { optStatusString.push("Topmost frame is Turbo Fanned"); } if (checkBitmap(optStatus,4096)) { optStatusString.push("Lite Mode"); } if (checkBitmap(optStatus,8192)) { optStatusString.push("Marked for Deoptimization"); } console.log(`${funcName}: ${optStatusString.join(", ")}`); } return { [funcName]: optStatusString.join(", "), }; };
※ここでは eval() を使わずに new Function() を利用してコードを式として評価している。
