            Bug ID: 935
           Summary: ISACaller doesn't handle instructions that write to
                    both RT and RS
           Product: Libre-SOC's first SoC
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: CONFIRMED
          Severity: normal
          Priority: ---
         Component: Source Code
          Assignee: lkcl at lkcl.net
          Reporter: programmerjake at gmail.com
                CC: libre-soc-bugs at lists.libre-soc.org
            Blocks: 933
   NLnet milestone: ---

I tried to fix it, I didn't get it to work, so didn't commit my changes. I
tried replicating what FRS does, but that seems very FFT-specific, and 3-in
2-out integer ops aren't all FFT ops.
