With the message in gcc.log being (all similar; requested number of gregs vary):
/home/hp/combined/mmixware-sim/gcc/collect-ld: Too many global registers: 260,
max 223

The test seems never to have worked on this target.
The failure to allocate the requested amount of global registers means that the
heuristic that the port uses to determine what constants and addresses are
suitable for a global register needs at least some tweaking (not hard),
alternatively that some mechanism needs to be invented in the binutils port to
work around this case (presumably possible, but at present I have no idea how).
Alternatively, make the test-suite compile the code with -mno-base-addresses for
mmix-*-*.
