It seems to me that V8 had very bad unit tests if this wasn't caught before release. Making sure all operators act the same way when optimized and not is a no-brainer.

Maybe, but I can also understand someone rationalizing that they don’t need to test abs(), because what could possibly go wrong?

>>sgarla+Ed8
Fair enough, it's busywork and easy to postpone. But code optimization is something that needs this kind of double-checking, so in the end you should have it for all opcodes, and then including the easy ones like abs isn't much extra work.
