Removing the SPARC backend would be a pity.
We use it in both teaching and research on embedded systems, targeting
the LEON3 processor from Aeroflex Gaisler [1].

In addition to the other objections raised in this thread, there are ongoing
efforts to build the RTEMS operating system with clang [2]. Quoting [2]:
