From: Segher Boessenkool Date: Mon, 16 Dec 2019 16:06:17 +0000 (+0100) Subject: rs6000: Use symbolic names for the CR fields in more cases X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=bb03700c9b89f42b9e6bccccef8a74ce9b4fb91b;p=gcc.git rs6000: Use symbolic names for the CR fields in more cases It turns out we still used hardcoded register numbers for the CR fields in some cases, and they now use the wrong numbers since we renumbered most of the registers. So let's use the symbolic names, instead. * config/rs6000/rs6000.md (movsi_to_cr_one): Use CR0_REGNO instead of hardcoding the (old, expired) register number. (*mtcrfsi): Ditto.
