Ken Tindall says

"I have seen what's been done for the 68HC11 with gcc:
the implementation had to provide virtual 16- and 32-bit
registers in RAM because gcc assumes a register rich
architecture. The code quality is consequently poor.
Of course, this is fine if all you want a free compiler to play
with."


Wonderful logic -- I have seen one attempt, it was poor, therefore it is
impossible to do right.

It is not true that gcc assumes a register rich architecture (after all
it runs on the x86). Yes, I agree that targetting to an architecture
like this will be more work, and that a half-baked job will be inefficient,
but don't assume that means it is impossible.
