            Bug ID: 842
           Summary: add Tininess-After-Rounding floating point flag --
                    needed for x86 and risc-v compatibility.
           Product: Libre-SOC's first SoC
           Version: unspecified
          Hardware: Other
                OS: Linux
            Status: CONFIRMED
          Severity: enhancement
          Priority: ---
         Component: Specification
          Assignee: lkcl at lkcl.net

   NLnet milestone: ---

OpenPower has Tininess-Before-Rounding, many widely-used architectures have
Tininess-After-Rounding instead. I think we should add a flag to allow
OpenPower to switch modes -- this is part of efficiently running x86 FP
operations on OpenPower (e.g. through qemu)
