Howards mentioned in another wrongly submitted issue (#9139) that "memcmp.c isn't even referenced in the Makefile, so none of this code is used." Here is the clarification, even if memcmp.c is not used, gcc or other compilers' implementations of memcmp is still unsafe (https://github.com/gcc-mirror/gcc/blob/master/libiberty/memcmp.c). -- Best regards, Shou C
