GCC-Compatible Warning Options

The Intel® C++ compiler recognizes many gcc-compatible warning options, but we do not document all of them.
In general, if a gcc-compatible option is accepted by the compiler, but not documented, the implementation of the option is the same as described in the gcc documentation.
To find the gcc documentation about gcc warning options, you can do any of the following:
  • Check the gcc website (
  • On Linux*, enter the command
    man gcc
  • Search the web for "gcc warning options"

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.
