Abstract
A method and apparatus to speculatively allocate a combinable store request buffer for a cache lock operation by setting an extended lock indicator. The store request buffer is speculatively allocated and the load-lock micro-operation associated with the cache lock operation is sent to a replay loop. During the replay window, conflict detection processing is completed. When the load-lock micro-operation returns from replay, the store buffer is de-allocated if a conflict has been detected during the replay window.
