问题描述
我有几个c ++项目，我试图找出项目中哪些循环是自动矢量化的，哪些不是自动循环的.我设置了/Qvec-report:1命令行开关，以便获得有关自动循环化了哪些循环的报告.
I have several c++ projects and I am trying to find out which loops in the projects are autovectorized and which aren't. I set the /Qvec-report:1 command line switch so I can get a report of which loops are autovectorized.
这样做在我的C ++项目中均未列出任何清单.
Doing so produced no listing in either of my C++ projects.
然后我切换到/Qvec-report:2
I then switched to /Qvec-report:2
这确实产生了一些关于未自动向量化的循环的报告，但未产生我项目中所有循环的报告，也未产生任何被自动向量化的循环的报告.
This did produce some reports about several loops that were not autovectorized, but it did not produce a report for all the loops in my project, no did it produce a report for any loops that were autovectorized.
我尝试了以下博客示例，网址为http://blogs.msdn.com/b/nativeconcurrency/archive/2012/05/01/auto-vectorizer-in-visual-studio-11-rules-for- loop-header.aspx
I tried several examples off of the blog here http://blogs.msdn.com/b/nativeconcurrency/archive/2012/05/01/auto-vectorizer-in-visual-studio-11-rules-for-loop-header.aspx
他们没有以任何一种方式生成报告.
and they produced no reports one way or the other.
谁能告诉我发生了什么事?
Can anyone tell me what's going on?
