I use Green Hills C (not the Mac/Lisa version) regularly for my work. Green
Hills C produces quite remarkable code. It is easily the best compiler for
the 68000 I have seen, for ANY language, by a long margin. For our
application, high resolution/high speed image processing, we found a code
speedup of better than 20% over Whitesmiths C (yecch), and 30% smaller code.
Because of its optimization, we have been able to get rid of a lot of code
that was written in assembly for speed. In some cases, GHC generated faster
code than the assembly code it replaced.

It does have some quirks: for instance, the optional optimizer pass doesn't
produce correct code, and the library code supplied was nonreentrant, buggy,
and nearly unusable. Green Hills is a very small company, so support is
sometimes a problem (the compiler was written by 1 programmer, who appears
to do ALL of the maintanence work for all of their compilers (C, Pascal,
Fortran for 68000 and 32000)).

Green Hills C for the Mac should be fantastic. I can hardly wait. We paid
$6000 for our compiler, and it was worth every penny. At $200-$500, it is a
bargain.
