Both are significantly slower than hand-coded loops. See r338963 for kernel commit. bcmp differs from memcmp by always returning 1 when a difference is found, as opposed to going for a value bigger or lower than 0 depending on what it is. This means it can do less work. For now the code is duplicated and modified. This will get deduplicated after another round of optimization when memcmp will get a longer-term form. Both tested with the glibc suite. While the suite does not have a test for bcmp, I created a wrapper routine which verified that values match (0 vs 0, 1 vs non-zero).
