foo(1);

Compiler removes empty loop and there is no endless loop that i expect. MSVC and GCC works correctly.

Not a valid win32 application
Hi,
I need to write a program that will run on a intel atom d525 processor with windows xp installed. I am using Parallel Studio 2013 with Visual Studio 2012.
When I tried running my code on the machine with windows XP I got the following error:
... is not a valid win32 application.
After some initial research I found out that this was because the console application compiled with Visual C++ uses windows APIs that are not available in windows XP and it has provided a special compiler with which you can compile code that is compatible for windows XP.
Accessing newest C++11 features on older Linux systems?
Anyone know how to be sure that ICC 13's C++11 support isn't a problem on older Linux systems?
ICC 13 on Linux uses the available version of GCC to supply libstdc and libstdc++. On CentOS/RHEL 6.4, the GCC version is 4.4.7. The associated version of libstdc++ lacks some C++11 features I'd like to use, but they're present in GCC 4.7.2.

Precise details about C++11 support
I'm using ICC 13.x, and I'm writing C++11 code.
This document
http://software.intel.com/en-us/articles/c0x-features-supported-by-intel...
tries to describe which C++11 features are supported. But some of the boxes list "Partial" support. Does anyone know where I can get more details on the level of support for those features?
For example, consider initializer lists. This statement compiles fine on GCC 4.7.2:
vector<int> x = {1,2,3};
intel c++ compiler for students
I tried to download Intel C++ Studio XE for Win, but there is a problem with my email address. The problem is that my university doesn't provide e-mails for students in *.edu :( the online form doesn't accept my current e-mail address.

Empty lines in Intel C++ compiler output for Debug configurations ( 32-bit & 64-bit )
I'd like to report an issue with Intel C++ compiler output for Debug configurations ( 32-bit & 64-bit ): There are empty lines and please take a look ( I marked empty lines with * empty * label ):
[ Intel(R) C++ Compiler XE 13.0.0.089 [IA-32] - Debug - There are empty lines ]
When could Intel C++ compiler support C++11 feature?
Dear all,
Recently I am trying to compiler some code by Intel C++ Compiler XE 13.0, the code is somewhat like the follows:
for(uint i=0; i<skeleton.size(); i++) {
for(auto &entry : skeleton[i]) {
action(i, entry.vid, entry);
}
}
when compiling by Intel C++ Compiler XE 13.0, the following error displayed:
Error 17 error : cannot deduce "auto" type (initializer required)
Does icl 13.0.1.119 support TSX?
Hello
Intel®Parallel Studio XE 2013 supposes to support TSX accordingly to its release information. But in my case, I don't see that. Maybe it because of misuse of commandline keys or misunderstanding of icl versioing. I don't know what asm compiler exactly is used by icl, but I suppose the one from its distribution.
Experiment was done on 64bit version of Windows with toy assembly routine.
Could someone clarify what is wrong?

Any detailed documentation on optimizations performed by the ICC?
Hi,
I am very interested in using the ICC long-term for low latency programming. Because of this I would like to try and get some documentation on the sort of optimizations the ICC does and doesn't do. Does this sort of documentation exist/are Intel able to provide something?
EDIT I would want to learn which micro optimizations are completely pointless, how the ICC implements various parts of the C++ language, optimizations performed, how the memory layout is organized etc. It would save many hours observing outputted assembler!
Thanks
