You can't just call Push()/Pop()/Drop() arbitrarily.
Ok I see what you mean, and actually you simply need something like a
property
read deoptimization in the first argument and it will crash:
// Flags: --allow-natives-syntax --noalways-opt
function callsFReceiver(o) {
return [].f.call(o.m, 1, 2, 3);
}
Array.prototype.f = function() {
return this.m;
};
var o1 = {m: 1};
var o2 = {a: 0, m:1};
var r1 = callsFReceiver(o1);
callsFReceiver(o1);
%OptimizeFunctionOnNextCall(callsFReceiver);
var r2 = callsFReceiver(o1);
callsFReceiver(o2);
var r3 = callsFReceiver(o1);
print(r1 === r2);
print(r2 === r3);
callsFReceiver(o1);
callsFReceiver(o1);
%OptimizeFunctionOnNextCall(callsFReceiver);
callsFReceiver(o1);
I was indeed arbitrarily calling the stack manipulation methods.
