I can't reproduce the failure, could you send the configure arguments for the
build.
I've tried assembling the string 'movw r0, 32768' and get the error when
-march=armv6kz or earlier. I suspect the new movhi and/or movhf patterns added
earlier in the series need the architecture level added as a precondition but
I'll need to look into it.
