METHOD FOR COMPARING RETURNED FIRST LOAD DATA TO DATA AT MEMORY ADDRESS REGARDLESS OF CONFLICTING WITH FIRST LOAD AND ANY INSTRUCTION EXECUTED BETWEEN FIRST LOAD AND CHECK POINT

A mechanism is provided for implementing an advanced load using a software-based check operation that eliminates the need for additional hardware. The check operation is implemented after a store that potentially conflicts with the memory address targeted by the advanced load. The check operation is implemented as a load and compare operation. The load accesses data at the target memory address and the compare determines whether the data returned by the advanced load matches that returned by the load.
