jit debugging

Error message: For details about calling real-time (JIT) debugging instead of the dialog box, See the end of the message. I don't know why I want to use such a difficult prompt, or I don't understand why. The cause of this error is as follows:1. The value is null.2. Use it without instantiation Therefore, the object is empty before use.If (OBJ! = NULL ){} URL: http://greatverve.cnblogs.com/archive/20

We can attach the debugger onto any running process at any time. Two cases:1. unhandled exception is thrown in some thread of a process. A dialog will pop up to ask user to terminate the process or debug it. if clicking OK, the process will be terminated; If cllicking cancel, the debugger specified in registry will be started up and attach onto the process and start JIT debugging.2. At any time, we can do t

Reference I wanted to introduce how to use SOS to debug CLR programs in windbg according to the command classification in the SOS help file, but it was not intuitive enough. Simply changed to based on my analysis of the actual cases of CLR, step by step introduced the function, although the structure is a bit confusing, it is more intuitive and easy to use. The previous two Articles respectively introduced the basic concepts of windbg debugging confi

The procedure was intended to introduce WINDBG using SOS to debug the CLR program in accordance with the sorting of commands on SOS's Help file, but it was not intuitive enough. Instead of the actual case of my analysis of the CLR, step by step introduces the function, which is a bit messy, but more intuitive and easy to start with:P The first two articles introduce the basic concepts of WINDBG debugging Configuration and threading, which will analyz

[Java Performance] JIT compiler IntroductionOverview of JIT compiler using JIT (Just-In-Time) JIT compiler is the core of JVM. It has the greatest impact on program performance. The CPU can only execute assembly code or binary code. All programs must be translated into them before they can be executed by the CPU. C

The meaning of this error is very clear, said is also very specific, the effect of translation into Chinese is in the use of--aot-only this option, and try to use the JIT compiler to compile the xxx method.Then do not know whether there will be crossing think this problem may be the program runni

The JIT compiler is one of the most efficient and important components of a Java Virtual machine (hereinafter referred to as the JVM). But many programs do not take full advantage of JIT's high-performance optimization capabilities, and many developers are not even aware of the extent to which their programs use JIT effectively.In this article, we'll show you some simple ways to verify that your program is

During the past two days, I have been preparing for the TechEd 2006 Session. From the foreign PPT, I found that in. NET CF 1.1, two types of JIT-sJIT and iJIT are supported. I didn't expect google to come to such an article and learn to understand it. So I will share it with you. The original Article is http://www.danielmoth.com/blog/2004_12_01_mothblog_archive.html. ---- Now, all. NET developers all know the managed code (using C #, VB. NET) are comp

During this period, the fault tolerance of. net jit is tested.CodeInserted to JIT for testing.This method is the first method I mentioned before to increase the kernel strength to prevent reflection and shelling.This technology can be used to protect DOTNET code, or to decrypt the DOTNET encryption shell. Currently, all encryption shells Insert the kernel into the EE to provide decryption services. The re

variable, but because stop is not volatile, this change can only occur in the Core1 cache, and the modified cacheline can theoretically never be brushed back to memory, In this way, the Core2 on the thread will never see the stop change.Two: JIT angle:Because the while loop in the Run method is executed many times, it is bound to trigger JIT compilation, the following to analyze the two cases of

of the execution engine, to form a complete meaning of the compiler to implement, such representatives are C/s language. It is also possible to implement a semi-independent compiler with the abstract syntax tree or the steps preceding the instruction flow, which is the Java language. Or you can put all of these steps together with the execution engine, like most JavaScript actuators. Javac CompilingWhen it comes to "compiling" in Java, it's natural to think that the Javac compiler compiles *.ja

This article will focus on the. NET reflection shelling machine Source code Based on the introduction, how to implement the JIT layer shelling machine. First, we chose to use C ++/CLI to complete this job. Reflection is required. Net. The jit-layer hook must use native C ++ functions.In this article, we assume that you have completed the hook JIT and interce

The JIT compiler compiles the bytecode into the machine code of the cost machine.Usually javac the program source code compiled, c
