Storing Bounds Information

The pointer checker is not supported on
macOS*
systems.
The pointer checker stores bounds information in a bounds table located in a memory address that is not adjacent to the memory address of the pointer. The pointer checker calculates this address by using the address of the pointer.
Because the bounds information is being stored in a separate memory address, use of the pointer checker in this module does not affect the data structure layouts and stack frames. You can check the bounds of pointers in enabled modules. Non-enabled modules will still work properly although this feature will not check the pointers in these modules.
When a pointer is loaded in a register, the compiler also loads the bounds from the bounds table. When a pointer is stored from a register, the compiler stores the bounds information in the bounds table.

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.
