; This is an out-of-line prologue.
;
; It performs the following operations:
;
;	* Saves the return pointer at sp - 20
;
;	* Creates a new stack frame (sp'), size of the frame is passed in %r21
;
;	* The old stack pointer is saved at sp (frame pointer version only).
;
;	* Saves grs (passed in low 16 bits of %r22 into the stack frame
;	at sp' + local_fsize (passed in %r19).
;
;	* Saves frs (passed in high 16 bits of %r22) into the stack
;	frame at sp' + local_fsize (passed in %r19).
;
;	* Sets up a frame pointer (in %r3) (frame pointer version only).
;
;	* Returns to the instruction _immediately_ after the call to
;	this function.
