I'd been on this whole rabbithole exploration thing of those MIT PCC 8086
uploads that have been on the site & on bitsavers, it had me wondering is
there any version of PCC that targeted the 386?
While rebuilding all the 8086 port stuff, and MIT PC/IP was fun, it'd be
kind of interesting to see if anything that ancient could be forced to work
with a DOS Extender..
I know there was the Anders Magnusson one in 2007, although the site is now
offline. But surely there must have been another one between 1988/2007?
Thanks!

I think it's a better than even chance that the C compilers in the first
versions of SCO and ISC Unix were based on PCC, you might look there.

Yes, I'm all but certain that ISC SVR3 used pcc (unless Heinz
contradicts). Dell SVR4 definitely had pcc, as well as 3(!) gcc versions

Definitely PCC based. We used that for all of our
ports of the UNIX system to different computer
system architectures.

As PCC (original version, not 2.0 or any of the Research Unix versions
after) was the compiler for BSD right up through 4.3, maybe some of the
early 386 BSDs used PCC too.

AIX for 386 also was likely pcc.

A cursory glance at the SVR4/386 SGS reveals some pcc fingerprints in the compiler bits at
/usr/src/cmd/sgs/cg
For instance the machine-dependent bits are shunted off to files including local.c and
local2.c, within these files exist similar entrypoints like lineid and zzzcode and arrays
like rnames and ccbranches. This is comparing with the version of pcc in V7. I
wasn't there so can't speak with authority but it does look like there is still
pcc DNA as of SVR4/386. Looking a bit further forward, this compiler seems to still be in
use as of 1997's UnixWare aka "SVR5".

A mirror of that work is available at https://github.com/arnoldrobbins/pcc-revived.
It's current as of the last time the main site was still online,
back in the fall of 2023.
Magnusson has more than once said he's working to get things back
online, but nothing has happened yet. I check weekly.
FWIW,
