Also, I suspect a benchmark with a larger loop body might not
benefit as significantly from branch hints as this one.
I disagree in longer loops code compactness is as important as
in small ones.
You must have misunderstood:
My thought was simply that with a larger loop body, LLVM might
not make such dramatic rearrangement of the basic blocks.
Take your straw man elsewhere :-/
This is more correct : (Tough for some reason it does not pass
the unittests)
You're only validating the first byte, current code validates all
of them.
