Also add separate tests for bcopy and bzero.
+2012-10-11 H.J. Lu <hongjiu.lu@intel.com>
+
+ * string/Makefile (strop-tests): Add bcopy and bzero.
+ * string/test-bcopy.c: New file.
+ * string/test-bzero.c: Likewise.
+ * string/test-memmove.c: Support bcopy test if TEST_BCOPY is
+ defined.
+ * string/test-memset.c: Support bzero test if TEST_BZERO is
+ defined.
+ * sysdeps/x86_64/multiarch/bcopy.S (bcopy): Jump to
+ __libc_memmove.
+ * sysdeps/x86_64/multiarch/bzero.S (__bzero): Jump to
+ __libc_memset.
+ * sysdeps/x86_64/multiarch/memset.S (__libc_memset): New alias
+ of memset.
+
2012-10-10 Joseph Myers <joseph@codesourcery.com>
* configure.in: Run $CXX, not cc1plus, to locate C++ headers.
