A data processing apparatus and method of operating such is disclosed. Issue circuitry buffers operations prior to execution until operands are available in a set of registers. A first and a second load operation are identified in the issue circuitry, when both are dependent on a common operand, and when the common operand is available in the set of registers. Load circuitry has a first address generation unit to generate a first address for the first load operation and a second address generation unit to generate a second address for the second load operation. An address comparison unit compares the first address and the second address. The load circuitry is arranged to cause a merged lookup to be performed in local temporary storage, when the address comparison unit determines that the first and the second address differ by less than a predetermined address range characteristic of the local temporary storage.
