            Bug ID: 657
           Summary: unit tests needed for BCD instructions
           Product: Libre-SOC's first SoC
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: CONFIRMED
          Severity: enhancement
          Priority: ---
         Component: Source Code
          Assignee: lkcl at lkcl.net

   NLnet milestone: ---

3 new instruction unit tests are needed, for BCD:

* addg6s
* cdtbcd
* cbcdtd

these are on p109 book I section 3.3.9 v3.0C

TODO checklist *in this order* due to dependencies (edit as needed):

* add cdtbcd unit test          - TODO
* add cbcdtd unit test          - TODO
* add addg6s unit test          - TODO

best to be added to decoder/isa/test_caller_bcd.py (new file) to save
iteration time (test_caller.py takes some time to complete).
