Technical solutions are described for executing one or more out-of-order instructions by a load-store unit (LSU) by detecting a load-hit-load (LHL) case based only on effective addresses (EA). An example method includes, in response to receiving a first load instruction, creating an entry in a LHL table. Further, in response to receiving a second load instruction in the load reorder queue, and in response to the predetermined number of bits from a second EA used by the second load instruction matching the predetermined number of bits from the first EA, comparing the first EA and the second EA. Further, a first thread identifier for the first load instruction is compared with a second thread identifier for the second load instruction. In response to the first EA matching the second EA, and the first thread identifier matching the second thread identifier, the method includes flushing the first load instruction.
