https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=244962 --- Comment #11 from Mateusz Guzik <mjg@FreeBSD.org> --- This is probably an optimization which is only there because of something wrong with headers. There is one fundamental discrepancy between bcmp and memcmp: the former only indicates there is a difference while the latter computes what it is on the first differing byte. Thus, if bcmp is provided and buffers differ, it has less work to do than memcmp and is a better pick if available. However, FreeBSD headers explicitly define bcmp as builtin_memcmp, therefore the above should not be happening if they are properly included and the defines are not overwritten. Once more this is just some build mess. -- You are receiving this mail because: You are the assignee for the bug.
