I installed Parallel Studio XE 2015 with MS Visual Studio 2013. When I ported an MSVC 2010 project, it compiled but failed to link with the cryptic error message "xilink: : error #10037: could not find 'llvm_com'". (It compiled correctly using MSVC 2010 with the Intel XE 2015 C++ compiler.)
The only reference to llvm in the Intel C++ documentation is to the Apple LLVM (Clang) compiler for XCode.
Any ideas?
