NOTE: Intel® Memory Protection Extensions (Intel® MPX) have been deprecated and are not available on all future processors.
Enabling an application to use Intel MPX will generally not require source code updates but there is some runtime code needed in order to make use of Intel MPX. For most applications this runtime support will be available by linking to a library supplied by the compiler or possibly it will come directly from the OS once OS versions that support Intel MPX are available. The runtime code has 3 responsibilities:
In future blogs I will go into more detail on how the runtime library manages bounds memory and handles faults.
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.
