1. A computer implemented method for load queue entry reuse for operand store compare (OSC) history table update, the method comprising: allocating a load queue entry in a load queue to a load instruction that is issued into an instruction pipeline of a processor, the load queue entry comprising a valid tag and a keep tag, wherein the valid tag is set and the keep tag is unset in the allocated load queue entry; flushing the load instruction by the instruction pipeline; based on the flushing of the load instruction, unsetting the valid tag and setting the keep tag in the allocated load queue entry; reissuing the load instruction into the instruction pipeline; determining that the allocated load queue entry corresponds to the reissued load instruction; based on determining that the allocated load queue entry corresponds to the reissued load instruction, setting the valid tag and leaving the keep tag set in the allocated load queue entry; completing the reissued load instruction in the instruction pipeline; and based on completing the reissued load instruction, and based on the valid tag and the keep tag being set, updating the OSC history table with OSC information corresponding to the load instruction.
