I tested s390 system for memcmp.   It returns -2 when optimized.
-----------------------------------------------
$ cat a.c
#include <string.h>
#include <stdio.h>

int
main (int argc, const char *argv[])
{
  printf ("%d\n", memcmp (argv[1], argv[2], 3));
  return 0;
}
$ gcc -O0 -g a.c && ./a.out abc abd
-1
$ gcc -O0 -g a.c && ./a.out abc abx
-21
$ gcc -O1 -g a.c && ./a.out abc abd
-2
$ gcc -O1 -g a.c && ./a.out abc abx
-2
