--- Comment #18 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I think it is a bad idea to introduce the IFUNC into libgcc_s, because then
while you speed up the few users of this builtin, you slow down all users of
libgcc_s (pretty much all C++ programs and lots of C programs), because they
will need to resolve the ifunc. For a very heavily used builtin perhaps, but
for a rarely used one it just isn't a good idea. User's can just use
multi-versioning themselves and use __builtin_popcount* in the multi-versioned
function.
