--- Comment #3 from Filip Kastl <pheeck at gcc dot gnu.org> ---
With the modification I plan for Stage 1 the DP alg will be as powerful as the
greedy alg here.

By LLVM code being better I suppose you mean this lower bound check:

        cmp     eax, 1
        jle     .L4

Yeah, it would be nice to come up with a way to get rid of it.
