Abstract
An apparatus includes a rescue buffer circuit, a store queue circuit, and a control circuit. The rescue buffer circuit may be configured to retain address information related to store instructions. The store queue circuit may be configured to buffer dependency information related to a particular store instruction until the particular store instruction is released to be executed. The control circuit may be configured to cause a subset of the dependency information for the particular store instruction to be written to the rescue buffer circuit. The rescue buffer circuit may be configured to retain the subset after the dependency information has been released from the store queue circuit, and to perform a subsequent load instruction corresponding to a memory location associated with the particular store instruction using the subset of the dependency information from the rescue buffer circuit.
