That said, GCC doesn't self-host on a lot of targets (mainly the microcontroller ones), so I don't think this is a big deal.  We should focus on making a modern cross-vax-gcc work correctly.  As far as the test suite goes, perhaps a way to remotely execute the generated binaries (on a real machine or in a simulator) that need to run to ensure the compiler generated the correct code is the way to go... maybe the GCC test suite already supports that, even.

Yes, that can be done.  With a "board file" you can hook the test suite to a simulator such as SIMH.  I've done a crude version of that for pdp11 execution testing.  Crude mostly because the libc I'm using is a very limited hack; the execution interface itself is not too bad.
