Subject: x86/string: Use `movsl` instead of `movsd` in strncpy/strncat [BZ #32344]
X-Git-Tag: glibc-2.41~493
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=c510681a6922eb96ec3f4585f71b97f73ae74388;p=thirdparty%2Fglibc.git

x86/string: Use `movsl` instead of `movsd` in strncpy/strncat [BZ #32344]

`ld`, starting at 2.40, emits a warning when using `movsd`. There is
no change to the actual code produced.
