            Bug ID: 1239
           Summary: sv.mcrf unit tests and in general for cr_ops needed:
                    SVP64
           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
          Reporter: lkcl at lkcl.net
                CC: libre-soc-bugs at lists.libre-soc.org
   NLnet milestone: ---

unit tests for CR-ops are a little behind the specification
https://libre-soc.org/openpower/sv/cr_ops/
also there is an "offset" for where predicates start
which is different from where Rc=1 stores vectors of
CR fields, which needs properly nailing down in the spec
(and unit tests)
currently listed as SVP64CROffs.CRPred this has to be
made dynamic
