New issue 1883 by [email protected]: Call::ComputeTarget should skip
transitions when looking for a CONSTANT_FUNCTION
http://code.google.com/p/v8/issues/detail?id=1883
Currently transitions will hide constant function and prevent inlining and
calls without IC:
function A () { }
A.prototype.foo = function () { }; // constant function on the prototype.
new A().foo = 0; // transition from the initial map.
function bar (o) { o.foo(); }
var o = new A();
bar(o);
bar(o);
bar(o);
%OptimizeFunctionOnNextCall(bar);
bar(o); // foo will not be inlined
