Abstract
One embodiment of the present invention provides a system for controlling cache line eviction. The system operates by first receiving a sequence of instructions at a processor during execution of a program, wherein the sequence of instructions causes a cache line to be loaded into the cache. Next, the system examines the sequence of instructions to determine if an associated cache line includes only scratch data that will not be reused. If so, upon loading the cache line into the cache, the system marks the cache line as containing only scratch data, which allows the cache line to be evicted next from the cache.
