FWIW, I think the work to add a df subreg liveness tracking problem
and use it in LRA/IRA would solve the live range problem without needing
a clobber. I wonder how that's going? In my last review I suggested
a change in representation (a single bitmap rather than per-register
bitmaps), but the general approach was good and very welcome. Hope I
didn't scupper the whole thing :(
I think Lehua may have left rivai, so I'm not sure there's someone
working on it right now.
