Hi v8-dev,
I read somewhere the other day that
y=Math.pow()
is much faster than
x=Math.pow
y=x()
because v8 can make a direct lookup of the symbol. I now wonder what
happens with polyfills of newly arrived functions like Math.cosh:
Math.cosh = Math.cosh || function(x) {
return (Math.exp(x) + Math.exp(-x)) / 2;
};
Is a polyfill breaking the optimization because the function was maybe
labeled as changed or did you consider this somehow?
Thanks Robert
