Comment #4 on issue 2898 by [email protected]: Double math used in int
context
https://code.google.com/p/v8/issues/detail?id=2898
Actually this was fixed soon after it was reported:
https://code.google.com/p/v8/source/detail?r=16943.
Note that we could even do a tiny bit better: When we see a truncating
multiplication by -1, we could replace it by a subtraction from 0, but
nowadays the performance difference between a multiplication and a
subtraction is not that big anymore. So we keep it as it is. Note 2: For
similar asm.js code, TurboFan is emitting this subtraction, so things like
this are OK in our shiny new future...
