===== 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。

LinuxLinux カーネルを用いたオペレーティングシステム

$ /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として評価している。
