Subject: (lshift_double): Replace `&' with `%' to fix typo.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=3d1877b1271889f9b1cc54d108b4363924343f29;p=gcc.git

(lshift_double): Replace `&' with `%' to fix typo.

(lshift_double, rshift_double): Truncate shift count only if
SHIFT_COUNT_TRUNCATED.  Remove unnecessary `count >= prec' test.
