Hi all,
This obvious patch changes the type of the rbit instruction to 'rbit'
rather than clz.
Tested arm-none-linux-gnueabihf.
P.S. The pipeline descriptions we have handle rbit, except
marvell-pj4.md but that one doesn't handle the current 'clz' type
either, so it will have not have a codegen impact.
Ok for next stage 1?
Thanks,
Kyrill
