Types of JIT Compiler

JIT (Just In Time) compiler converts non executable (MSIL) code to executable (native) code.This process is also called Dynamic Translation.
Following are the types of JIT compiler.

(1) PRE JIT Compiler
(2) ECONO JIT Compiler
(3) NORMAL JIT compiler

(1) PRE JIT Compiler

Pre-JIt compiler compiles complete source(MSIL)code to Native code in a single Compilation.

(2) ECONO JIT Compiler :

This compiler compiles only MSIL code of those methods that are called at Runtime.

(3) NORMAL JIT compiler:

This compiler compiles only MSIL code of those methods that are called at runtime and that converted (native) code is stored in cache.This happens because,when these methods called again it will retrieve code from cache itself without sending request to CLR.Thus,in turn saves much of executiom time

My first OpenSource initiative

Recently during my study i developed C++ port of some functionality available in .Net languages. I was already familiar with some of the .Net port of applications and frameworks available for Java such as NUnit and NAnt. So i have decided to develop some of the classes in C++ which are available in .Net . I have uploaded classes to here.Feel free to download and use these classes.I am a beginner level programmer so there is possibility for classes to contain errors so if you find any error and or have any suggestion, just mail me at vbmade2000@gmail.com.
