* sysdeps/i386/i686/multiarch/strcmp-sse4.S (__strcasecmp_sse4_2)
(__strncasecmp_sse4_2) [PIC]: Restore %ebx before falling through
to __strcasecmp_nonascii and __strncasecmp_nonascii.
* sysdeps/i386/i686/multiarch/strcmp-ssse3.S (__strcasecmp_ssse3)
(__strncasecmp_ssse3) [PIC]: Likewise.
2013-08-26 Roland McGrath <roland@hack.frob.com>
* io/lxstat64.c: Just call __xstat64, for parity with stub __lxstat.
