If the port does get occasional fixes (primarily driven by BZs),

LRA, conversion to RTL prologue/epilogue, etc), may be only getting
occasional testing, etc. Then it's probably fair to call it in
maintenance mode. A great example IMHO would be the m68k.
Another criteria would be available hardware for which both the PA
and alpha ports are a good example. When you can't buy new hardware
then targets that could formerly host GCC quickly rot to the state
where only cross-compilation is viable (and having "old" GCC is good
enough).
Very true. Actually the PA is the best example there. Alpha I believe
has a functional-enough QEMU port to do real work and m68k has Aranym
which I've used to bootstrap m68k within the last 18 months. Hell, I
think Aranym actually ran faster than the last shipping real hardware!
You can still buy m68k based chips (e.g. Freescale ColdFire) for
embedded systems.
