From: Philipp Tomsich <philipp.toms...@vrull.eu>
The decoding of the following instructions from Zb[abcs] currently
contains decoding/printing errors:
* xnor,orn,andn: the rs2 operand is not being printed
* slli.uw: decodes and prints the immediate shift-amount as a
register (e.g. 'shift-by-2' becomes 'sp') instead of
interpreting this as an immediate
This commit updates the instruction descriptions to use the
appropriate decoding/printing formats.
