;; See file "rtl.def" for documentation on define_insn, match_*, et. al.

;; The V851 manual states that the instruction address space is 16M;
;; the various branch/call instructions only have a 22bit offset (4M range).
;;
;; One day we'll probably need to handle calls to targets more than 4M
;; away.
;;

;; Condition codes
;;
;; Data movement (load, store, register copy) does not modify condition
;; codes.  But there is no way to add two registers together without
;; modifying the condition codes.
;;
;; So we do not expose the condition codes until after reload.  The
;; general approach is to have a define_insn_and_split for the basic
;; operation with no condition codes in the pattern (to give the
;; optimizers maximal freedom).  The splitter adds a clobber of the
;; condition codes after reload.  There is a distinct pattern which
;; sets the condition codes.
;;
;; As noted, data movement does not affect condition codes.
;;
;; Arithmetic generally set the codes in the expected ways, with mul
;; instructions being a notable outlier.  div instructions generally
;; do the right thing, except when the output registers are the same
;; when the flags do not get set.  We just assume they're clobbered
;; for div instructions to avoid MD bloat with marginal benefit
;;
;; The bit manipulation instructions (clr1, not1, set1) set condition
;; codes, but not in a useful way (they're set to the prior status of
;; the bit).  So we just model those as clobbers.  tst1 does set the
;; condition codes in a useful way.  We could perhaps do better with
;; these by noting they only modify the Z flag, it doesn't seem worth
;; the effort.
;;
;; Byte swaps seem to change the condition codes, but I haven't tried
;; to describe how.
;;
;; I have no documentation on the rotate instructions.  They likely
;; set the condition codes, but I've left them as clobbers for now.
