So far we have generated code that is 100% equivallent to the methods byte code. But in case of exception this is a little problematic. Let ...

Execution of native methods are easiest of all methods :D. Since we dont need to generate anything for them - they are already native. We ...

Now we have our object on the heap. We need mechanism to putfield and getfield . The operation is very simple indeed. First we need a hel...

Lets create object on heap today. Since we have the object creation code in JavaClass it is very easy to create an object on the heap. We...

Well, its not really wrong- its just efficient- The stack top is is always topvalue + 1. This is not right behaviour for stack usually- bu...

The Jxx instructions I used for branching was not working right- It treated values unsigned. The "IA-32 Intel Architecture Software Dev...

Today I'll generate code that can handle conditional branch. This one is really gian step- since once we have conditional branching enab...

Today I'll try to extend the simple JIT compiler to the point where we can call a method from another method. First lets create a simp...

Today we'll design a small block of code that is equivallent to a corresponding java method. Since the generated native executable cod...

First we need to generate executable code block. So let us write some code in C++. int add(int x, int y) { int r; r= x+y; ...
