            Bug ID: 1204
           Summary: New PowerISA Compliancy Subsets for 64-bit LE: SFS64
                    and SFFS64
           Product: Libre-SOC's first SoC
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: DEFERRED
          Severity: enhancement
          Priority: ---
         Component: Specification
          Assignee: lkcl at lkcl.net
          Reporter: programmerjake at gmail.com

                    programmerjake at gmail.com
   NLnet milestone: Future
    parent task for 487
 budget allocation:

I have previously mentioned that I think there should be 2 new compliance
subsets: SFS64 and SFFS64 that require 64-bit LE with BE optional and they
specify the full set of instructions expected to be on any 64-bit processor
(e.g. are quadword-atomics required? what about cfuged?)
