Subject: rs6000: fix for PR61396 (wide-int fallout)
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b50a9d38941a6a3aa42b9a9e89c5bf5dfb509ed1;p=gcc.git

rs6000: fix for PR61396 (wide-int fallout)

CONSTANT_P is true for more than just all kinds of constant number.
This patch undoes that part of the wide-int patches.
