;; In this MD file, we define those insn patterns that involve
;; registers, where such registers are virtual until allocated to a
;; physical register.  All of these insns need to be conditional on
;; rl78_virt_insns_ok () being true.

;; This tells the physical register allocator what method to use to
;; allocate registers.  Basically, this defines the template of the
;; instruction - op1 is of the form "a = op(b)", op2 is "a = b op c"
;; etc.
