@CarlosAlbertoEnciso thanks for investigating this and testing out a new way to collect debug values. Given the complexity of replacing the current algorithm, and that it's not strictly related to fixing MachineCSE, I'd recommend keeping the current algorithm (i.e not using MachineRegisterInfo for now). That will allow us to land a fix in tree soon and hopefully iterate on it.
