You do not need to resolve/rename memory addresses. You need to resolve/rename stack addresses, which is entirely different problem, much smaller than working with memory addresses. There are usually not more than 2 stack addresses to rename, even less than number of registers. If I remember correctly, Elbrus 2 CPU had external stack ISA and internally it was register-based OoO core. The Elbrus team was bought wholesomely by Intel after USSR collapse and one of the rumors behind the name of Pentium chip line name was that it was named after Pentkovskij: https://en.wikipedia.org/wiki/Vladimir_Pentkovski https://en.wikipedia.org/wiki/Vladimir_Pentkovski
