            Bug ID: 579
           Summary: c/c++ macros for inline assembly supporting svp64
           Product: Libre-SOC's first SoC
           Version: unspecified
          Hardware: Other
                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: ---

c macros and c++ inline classes are needed which allow for svp64 inline
assembly to be created without (initially) modifications to gcc or binutils.

initial scope is to restrict incoming and outgoing registers from inline
register-to-variable parameters to r0-r31 / fp0-fp31

"internal" assembler known as "basic" asm is not so restricted.
