The section H.12 of the SPARC Architecture manual outlines the whole register remapping process that requires the re-allocation of `%oN` to free `%gN` registers if needed, I didn't implement the whole thing because of time/interest constraints but as it's written it should be relatively easy to add the missing steps.
