The compiler samples included with Intel® C++ Composer XE are designed to illustrate specific compiler optimizations, features, tools, and programming concepts.
Many of the samples are small, single source files intended to illustrate the associated concept in a general way. Others are provided in .tar.gz files. Please ensure that any files used are copied or untarred into a writeable directory. The sample sources contain the command line options and, where applicable, environment settings needed for compilation on Linux*, OS X*, and Windows*.
Some of these samples are meant to illustrate features during compilation only and do not result in executables.
Samples are located in <install-dir>/composer_xe_2013.X.XXX/Samples/en_US/C++.

|
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 regardīng the specific instruction sets covered by this notice. Notice revision #20110804 |
