;;; So, what do we want to do here?
|
||||
;;; 1. we eliminate all variables:
|
||||
;;; bind should become a sequence of (setfv i <value>) statements
|
||||
;;; variable refs should befome (fv i) where i is the index of
|
||||
;;; the var on the stack.
|
||||
;;; 2. we need to keep track of the maximum stack size used; and
|
||||
;;; whether we made a procedure call so that we can insert a
|
||||
;;; stack overflow check with an appropriate size check.
|
||||
;;; 3. as we generate code, we need to keep track of which stack
|
||||
;;; locations contain pointers so that procedure calls can
|
||||
;;; set an appropriate mask.
|
||||
;;; 4. primitives that allocate, as well as closures and fixes
|
||||
;;; should insert an appropriate alloc-check marks as well as
|
||||
;;; keep the live masks for the later generation of trap handlers
|
||||
;;; 5. primcalls should also keep track of liveness information
|
||||
;;; and frame size just in case the primitive needs to make a
|
||||
;;; procedure call.
