            Bug ID: 1099
           Summary: 16-bit fpr load/store needed for bfloat16 and
                    f16/bfp16
           Product: Libre-SOC's first SoC
           Version: unspecified
          Hardware: Other
                OS: Linux
            Status: CONFIRMED
          Severity: enhancement
          Priority: ---
         Component: Specification
          Assignee: lkcl at lkcl.net
          Reporter: programmerjake at gmail.com
                CC: libre-soc-isa at lists.libre-soc.org
   NLnet milestone: ---

since memory-access sizes are not changed by svp64, we need 16-bit fp
load/store instructions for f16 and bfloat16. since they are less common and
require svp64 prefixing anyway, they can go in ext200.
