It will return false during and after register allocation. Your code is being called at that time somehow, probably during reload. You have to either ensure that that does not happen, or, more likely, you have to arrange to use an existing register rather than create a new one. For example, look for uses of can_create_pseudo_p in mips.c. Ian
