In GCC-3.3.3 timeframe, you said that applying these patches would need
patching the SPARC back-end so we did not take any action. Now that the
branch is open again, I would like to know whether you look into this or
not. It is uncomfortable that the SPARC back-end is blocking other
back-end because of a bug in the SPARC back-end,..
Thanks,
