The CBO instructions were, AFAIU, disassembled erroneously.
In addition, lq (load-quad, a RV128 instruction) shares the same
opcode space as the CBOs, which also led to incorrect dasm for that
instruction (understandable since RV128 is an experimental feature).
To avoid overlaps, we now require that lq is decoded only if
rd is not 0, as CBO requires the field corresponding to rd to be zero,
both in dasm and decodetree.

Change in v2:
- Move the last v1 patch to the first place to correct the original
   indentation that was making checkpatch unhappy before doing the
   real work.
   (Note that disas/riscv.c has overall many checkpatch issues, this
   patch only solves the indentation one, but otherwise keeps the
   same "style" as the rest of the file)

Daniel, I took the liberty to keep your "Reviewed-by" tag, as only
patch order and indentation changed.

Yes sir.


All patches are fine for the code freeze IMO.  Thanks,

Daniel


Frédéric Pétrot (3):
   disas/riscv.c: Correct indent for checkpatch
   disas/riscv.c: Correct wrong shifts for cbo
   disas/riscv.c: Correct disasm of lq
