--- Comment #5 from Segher Boessenkool <segher at gcc dot gnu.org> ---
So:

-- LLVM should support "wa", since that is *the* constraint for VSX registers.
-- musl should use the "wa" constraint in its inline asm.
-- If after those two you still want "ws" (for compiling legacy code, say), I
   can add that back to GCC 10 (it will do just the same as "wa").

Is that a plan?
