You are right about gcc; version 1.37 (and I think a later version too)

a drop in replacement for, Apple's compiler. In fact, when I was porting
TeX -- at the time, considered a large program -- only gcc would compile
it successfully.
Long before that, I used Whitesmiths C, Aztec C, and of course
Lightspeed/THINK C on Mac for 68K.

It would have been impossible to use GCC on the 8560, it was a V7
PDP-11 Unix. The 64000 processor is pretty much the same as the HP 9845.
In 1983 there was Alcyon on the 8560 :-) (woa. that was a long time ago)
It only worked because they #ifdef'd out the floating point support.
Split I&D on a pdp-11. Not much space.
I'm not aware of any native TEK C compiler for 68k on the 8560.
In 1987 gcc would compile to 68k quite well. Before that I seem to
recall that there was also a C compiler from Standford, from sumex (wow
- do I still have those brain cells?). Remember sumex-aim ? SumMacC.
Anyway, I think the Kinetics fastpath was compiled with that and I could
swear I was using it as a C compiler on a vax-11/750 running mt. xinu in
mid 80's. Find someone from pixar - they were using it to compile
Macintosh code. I don't know the lineage of that compiler, but I think
it was a port of something older. Arg,
totally forgot to include the HP 64000 and Tek 8560 development
systems though I'm
blanking right now on if they did their own or sold third-party C
compilers.
Third party, I believe. I used one of those for a 68040 (developing
the DECbridge 900). I think the compiler was Green Hills. GCC was
around, I think, but that isn't the one we used as far as I remember.

There was also another C compiler we ran on the vax ...
I think gcc was the standard for 68k from 1987 on. Yes, greenhills, but
it's not clear it produced better code and it was really expensive. Ask
anyone at cisco or wellfleet what they used. And trust me, they were
worried about code size and code speed. lol. I remember trying to
route at "wirespeed" using 10baseT. Makes me laugh now.
