[webkit-dev] DFG jit Type checking

I'm trying to figure out how does the DFG JIT type checking work?
I'm also interested in the following: if I start DFG JIT without using LICM
will the types of variables be checked in the cycle? To make it clear, I'll
bring this example
for (var j=0; j<10000; j++)
        var i = 10;
        var h = j + i;

How will the type of variable " i " be checked in that example?
