This should get inlined if you just optimize f I think.

[Jakob Kummerow, 2011/04/11 12:55:51]

No: "Did not inline max called from f (target not inlineable).", and it doesn't
get optimized either without the explicit statement.
Want me to remove %OptimizeFunctionOnNextCall(f); instead? I guess that's not
really required for this test.

[Mads Ager (chromium), 2011/04/11 13:03:44]

I agree with you. What should matter here is that Math.max gets optimize.
Introducing f just to give Math.max a shorter name seems unnecessary. Replace
all calls to f with calls to Math.max, optimize that and check the results? 

[Jakob Kummerow, 2011/04/11 13:27:04]

Done.

+%OptimizeFunctionOnNextCall(f);
+f(0, 0);
 
 var r = f(-0, -0);
 assertEquals(-Infinity, 1 / r);
