Subject: x86/string: Use `movsl` instead of `movsd` [BZ #32344]
X-Git-Tag: glibc-2.41~504
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=6754b5becf403a3c6b95a0ebd829edf8e4d83251;p=thirdparty%2Fglibc.git

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

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