Every report (-opt-report, -vec-report, -par-report, -openmp-report) now put under single –opt-report interface

Other report options will still work, but report information generated and the way it’s generated will map to new model

Output now defaults to a one report file per generated object model. Can be changed using –opt-report-file=<filename|stderr|stdout>.

Report information designed to be more readable and actionable

Optimization Notice

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.
