Comment #9 on issue 2513 by [email protected]: life benchmark slowness
http://code.google.com/p/v8/issues/detail?id=2513
I think the issue is not quite
---
function toInt(b) { return b ? 1 : 0; }
---
but more
---
var x = (f()|0) > 0 ? 1 : 0;
---
That is, we know that the input to the conditional is a boolean value. If
we know that, then it should be possible to optimize that much better than
if we just receive a value b of unknown type. And then, it seems just as
simple to optimize for
---
var x = ((f()|0) > 0) | 0;
---
like comment #8 says.
