Instruction definition to implement load store reordering and optimization

A method for forwarding data from the store instructions to a corresponding load instruction in an out of order processor. The method includes accessing an incoming sequence of instructions, and of said sequence of instructions, splitting store instructions into a store address instruction and a store data instruction, wherein the store address performs address calculation and fetch, and wherein the store data performs a load of register contents to a memory address. The method further includes, of said sequence of instructions, splitting load instructions into a load address instruction and a load data instruction, wherein the load address performs address calculation and fetch, and wherein the load data performs a load of memory address contents into a register, and reordering the store address and load address instructions earlier and further away from LD/SD the instruction sequence to enable earlier dispatch and execution of the loads and the stores.
