--- Comment #2 from Martin Liška <marxin at gcc dot gnu.org> ---
Switch conversion bails out because it knowns that a jump table (or a bit test
can) be used for this snippet. Then we prefer to use a jump table then a bit
test. With -fno-jump-tables we generate the same code.
That said, I confirm it's a small limitation.
