--- Comment #3 from ktkachov at gcc dot gnu.org ---
GCC does disable some pattern recognition with
-fno-tree-loop-distribute-patterns, which is implied by -ffreestanding (used by
the kernel). Wouldn't it be consistent to disable this pattern recognition in
that setup as well? popcount is not such a fundamental helper function like
e.g. DImode shifts, after all
