Subject: picochip.md (cbranchhi4): No :CC for match_operator.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=43660e0b3a22e65b7ad01521748d10e71fab050e;p=gcc.git

picochip.md (cbranchhi4): No :CC for match_operator.

        * config/picochip/picochip.md (cbranchhi4): No :CC for match_operator.
          The instruction is then expanded explicitly.
        (supported_compare): Callable instruction.
        (compare): Likewise.
