Declaration in Scope of Function Defined in a Namespace

In accordance with the C++ language specification, if a function declaration is encountered within a function definition, the function referenced is taken to be another member of the namespace of the containing function; regardless of whether the containing function definition is lexically within a namespace definition. The Microsoft* Visual C++* compiler takes the referenced function to be a global function (not in any namespace).
Functions declared in global or namespace scopes are interpreted the same way by both the Intel® C++ Compiler and the Microsoft* Visual C++* compiler.

Product and Performance Information


Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
