--- Comment #1 from Hans Wennborg <h...@chromium.org> ---
This was fixed in r262575.
This test case is also interesting in x86_64, where LLVM will do the tail call,
but first reduntantly zext's the argument.
I sent a patch out: http://reviews.llvm.org/D17973, but the ABI situation is
pretty confusing and the benefits probably not that big, so I'm putting that on
the back burner.
