Abstract: Systems, methods, and apparatuses relating to circuitry to precisely monitor memory store accesses are described. In one embodiment, a system includes a memory, a hardware processor core comprising a decoder to decode an instruction into a decoded instruction, an execution circuit to execute the decoded instruction to produce a resultant, a store buffer, and a retirement circuit to retire the instruction when a store request for the resultant from the execution circuit is queued into the store buffer for storage into the memory, and a performance monitoring circuit to mark the retired instruction for monitoring of post-retirement performance information between being queued in the store buffer and being stored in the memory, enable a store fence after the retired instruction to be inserted that causes previous store requests to complete within the memory, and on detection of completion of the store request for the instruction in the memory, store the post-retirement performance information in storage of the performance monitoring circuit.

Abstract: Methods and apparatuses relating to memory corruption detection are described. In one embodiment, a hardware processor includes an execution unit to execute an instruction to request access to a block of a memory through a pointer to the block of the memory, and a memory management unit to allow access to the block of the memory when a memory corruption detection value in the pointer is validated with a memory corruption detection value in the memory for the block, wherein a position of the memory corruption detection value in the pointer is selectable between a first location and a second, different location.
