--- Comment #7 from Jonathan Wakely <redi at gcc dot gnu.org> --- Hmm, yes, the code for bitset<N>::set() is actually similar to what we get for foo() in comment 5. The new version with memset does produce different (vectorized?) code though. For operator== the current code is quite branchy, and looks better with memcmp to me (but I don't really know what I'm talking about).
