For example, in MIPS there are HI/LO registers that need to be accounted for. You could call those "misc." registers, but in reality those are part of the integer register file. So what I'm getting at is, are you sure that those registers (control/count/etc.) should be specified as misc. registers?
To my understanding, misc. registers should be registers that are controlled by the kernel (and probably some larger system state), thus you want to be careful about speculating on those types of registers. If you are convinced that the registers that you refer to are really just extra integer registers, than adding them to the Integer register file will probably solve your problem. But if those registers are indicative of some other system state then a more elegant solution is probably in order... Any one else have thoughts? -- - Korey
