Vector Store Indexed Least Recently Used

Purpose

Stores a 16-byte vector into memory at the address specified by a displacement and a pointer, ignoring the four low-order bits of the calculated address, and marking the cache line containing the address as least frequently used.

Operation

A memory address is obtained by adding b and c, and masking off the four low-order bits of the result. The 16-byte vector in a is stored to the resultant memory address, and the containing cache line is marked as least frequently used.

Notes

This intrinsic can be used to indicate the last access to a portion of memory, as a hint to the data cache controller that the associated cache line can be replaced without performance loss.
