--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Yeah, I see it too. The caller guarantees blocks.length () is at least 1 (as
it always pushes entry_block in there), so in
qlen = blocks.length () - 1;
qin = qout = worklist =
XNEWVEC (basic_block, qlen);
qlen is never -1U, but the compiler doesn't know this.
