--- Comment #6 from Marc Glisse <glisse at gcc dot gnu.org> --- Ignoring strange specializations of char_traits, we could also consider a specialized version of memcmp/strncmp that checks for a terminating 0 in only one of the 2 strings. This would avoid the call to strlen when the 2 strings are long but differ early, but on average it would probably turn out slower than the well optimized strlen+memcmp from libc.
