Hi ,
      Can some one tell me how the concept of callee -save and caller
save registers ties in with register allocation process in general. I
understand the process of register allocation, but wonder how this
restriction ties with the process. My only guess is that it acts as a
constraint when assigning registers, so some values have to be put in
either callee save or caller save based on the convention. Is that how
it is ?


thanks
Shrey
