Embodiments herein provide for improved store-to-load-forwarding (STLF) logic and linear aliasing effect reduction logic. In one embodiment, a load instruction to be executed is selected. Whether a first linear address associated with said load instruction matches a linear address of a store instruction of a plurality of store instructions in a queue is determined. Data associated with said store instruction for executing said load instruction is forwarded, in response to determining that the first linear address matches the linear address of the store instruction.
