Abstract
A load/store unit includes a first queue including a first entry for a store operation and a second queue including a second entry for a load operation that includes a return instruction that redirects a program flow to a location indicated by the return instruction. The load/store unit also includes a processor to determine that the store operation matches the load operation and selectively perform store-to-load forwarding (STLF) of a return address for the return instruction from the first entry to the second entry based on whether the store operation is associated with a call instruction. The load/store unit forwards the return address to the second entry in response to the store operation being associated with the call instruction. The load/store unit blocks forwarding until the store operation retires in response to the store operation not being associated with the call instruction.
