            Bug ID: 1187
           Summary: ori 0, 0, 0 not executed properly
           Product: Libre-SOC's first SoC
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: CONFIRMED
          Severity: minor
          Priority: ---
         Component: Source Code
          Assignee: programmerjake at gmail.com
          Reporter: programmerjake at gmail.com
                CC: libre-soc-bugs at lists.libre-soc.org,

   NLnet milestone: ---

it gets decoded as "nop", but that's an alias -- the actual instruction is "ori
0, 0, 0" so when it gets run, ISACaller thinks it's an illegal instruction.

I think we should add a special case to allow running code spelled as "ori 0,
0, 0" too, since we support all other base instructions rather than aliases.
