Generating ARM code for a managed assembly on an Intel machine

由 若如初见. 提交于 2019-12-20 05:24:12
问题 Directly related to this question. Given a managed assembly for Windows Phone, how can I generate native code for it for an ARM CPU? I don't have a Windows/ARM device (neither tablet nor a phone). There's the ngen utility out there, but AFAIK it can only generate code for the host machine (i. e. Intel). The reason why I'm asking, the offsets in the crash stack that Windows Phone Dev Center provides are not MSIL offsets (I've checked - they go way beyond MSIL function size). Those look like

How do I prevent NGEN from rebasing my code (negatively affecting performance)?

问题 I simply want to speed up my .NET-base client side app and am considering NGEN-ing the code. Jeffery Richter wrote this warning about ngening code: •Inferior Load-Time Performance (Rebasing). When Windows loads an NGend file, it checks to see if the file loads at its preferred base address. If the file cant load at its preferred base address, then Windows relocates the file, fixing-up all of the memory address references. This is extremely time consuming because Windows must load the entire

Does it help to use NGEN?

问题 Is it better to use NGEN an ASP.NET application when we know it is not going to change much? Or is the JIT good enough? The only reason I asked was because this article by Jeffrey Richter in 2002 says : And, of course, Microsoft is working quite hard at improving the CLR and its JIT compiler so that it runs faster, produces more optimized code, and uses memory more efficiently. These improvements will take time. For developers that can't wait, the .NET Framework redistributable includes a

How does ngen works?

问题 So, from what I understand, it does take an executable/dll file written in MSIL and does the JIT-job: convert MSIL code to native machine code. Right? So ran the ngen to generate a native image of my program using the command: ngen install myProgram.exe It take a while but I found the generated file is at C:\Windows\assembly\NativeImages_v4.0.30319_32\myProgram\db1496cf0295bbe6a9242d86c0d8e091\myProgram.ni.exe But what's exactly the contents of that executable file? a machine code version of

.NET assembly cache / ngen / jit image warm-up and cool-down behavior

问题 I have an Input Method (IME) program built with C#.NET 2.0 DLL through C++/CLI. Since an IME is always attaching to another application, the C#.NET DLL seems not able to avoid image address rebasing. Although I have applied ngen to create a native image of that C#.NET 2.0 DLL and installed it into Global Assembly Cache, it didn't improved much, approximately 12 sec. down to 9 sec. on a slow PIII level PC. Therefore I uses a small application, which loads all the components referenced by the C

How to determine if assembly has been ngen'd?

问题 How can you determine whether a particular .Net assembly has already been ngen'd or not? I need to check from code. Even invoking the command-line would be fine. At the moment I can't see any way of determining this. 回答1: You can try to find your assembly in "ngen cache" (C:\Windows\assembly\NativeImages_v2XXXXXXX). Сached assemblies will have the following format name: [basename]. ni .[baseextension] . 回答2: Check From Code Check if we are loading an native image for the executing assembly. I

How do I run nGen at the end of the installation (MSI)?

问题 I would like to execute nGen at the end of my installation simply to improve the perceived performance of the first startup of my application. How could I do that? Is there are some best practices? Can I be sure that nGen is always installed with .NET Framework? Thanks! 回答1: You can ngen your assembly using a custom installer action. The following link explains this in further detail: http://www.dotnetperls.com/ngen I can also remember a good discussion of Paint.NET's installer (which

Can we disassemble (using ILDasm) an NGen-ed assembly?

由 ╄→гoц情女王★ 提交于 2019-12-04 17:38:03
问题 If I NGen an assembly, is it normal that ildasm still disassembles it? Ok. I wrote a HelloWorld class library and the ensuing dll is named NGenILDasmTest.dll. --> Targeted for the .Net fw 4. From Vs 2010 command prompt, I did gacutil -i NGenILDasmTest.dll I could see the assembly installed in the GAC. And I ran ildasm so I could view the IL. So far so good. Then I run ngen NGenILDasmTest.dll (I did not specify any options for ngen). And this assembly successfully got compiled. I located it

Does it make sense to distribute pre-NGEN-ed assemblies?

I've found a few interesting links on using NGEN as a final step in an installer from this post . Is there a reason it is preferred to NGEN your assemblies at setup time, instead of at build time? I'm not particularly concerned with setup time, but it just seems like an unnecessary step that could be automated by my build. NGEN output is computer/CPU specific. your build machine will probably not be the production machine (maybe different DotNet version, AMD ? INTEL... who knows..) 来源： https://stackoverflow.com/questions/1779093/does-it-make-sense-to-distribute-pre-ngen-ed-assemblies
