- ;; The vax has no sltu or sgeu patterns, but does have two-operand
- ;; add/subtract with carry. This is still better than the alternative.
- ;; Since the cc0-using insn cannot be separated from the cc0-setting insn,
- ;; and the two are created independently, we can't just use a define_expand
- ;; to try to optimize this. (The "movl" and "clrl" insns alter the cc0
- ;; flags, but leave the carry flag alone, but that can't easily be expressed.)
- ;;
- ;; Several two-operator combinations could be added to make slightly more
- ;; optimal code, but they'd have to cover all combinations of plus and minus
- ;; using match_dup. If you want to do this, I'd suggest changing the "sgeu"
- ;; pattern to something like (minus (const_int 1) (ltu ...)), so fewer
- ;; patterns need to be recognized.
