--- Comment #2 from Richard Smith <richard-llvm at metafoo.co.uk> ---
'zeroext' on a parameter means that it's zero-extended by the caller. That's
correct here; the x86 psABI requires this extension.

If this function isn't working due to the parameter not being zero-extended,
that seems to be a bug in the caller, not the callee. If that code was also
generated by LLVM, please reopen this.
