Cross compilation, I assume. Doesn't matter to me, I just want to
know if anyone's using it.

Yes. Dunno if it could be made to work with overlays or something,
but it'd be very slow.

Not only is size a problem, but even as a cross-compiler it is lacking.
I am pretty sure support for the PDP stopped many releases ago and even
at the peak of support I don't believe there was ever as or ld support
for the PDP. I have considered reviving the PDP cross compiling work
and looking at writting a translator to take the output from -S (which
I am quite certain would be AT&T format) and convert it to Macro-11.
I usually end out weighing this against the work necessary to just write
a C-compiler for the PDP (using Small C as a starting point). If only
I could retire so I'ld have the free time. :-)

I added PDP-11 support to GNU binutils last year. It's not well
tested, though.

Two things.
1. DECUS C might be a better starting point.
2. With DECUS C, you also have an as, which might fit the bill without
having to convert stuff to Macro-11.

Consider lcc, the Princeton C compiler. It's much smaller than gcc, and ANSI
compliant.

How about the 2.11BSD compiler?

The next question is, why to do this, and for which operating system(s)?
If it's to get an ANSI C compiler, or some extra performance, then I
can see the point. If it's to ditch a `contaminated' compiler, then
I can see a few difficulties, especially if the target is 2.11BSD
The 2.11BSD linker knows an awful lot about overlays, and any replacement
would need to do the same.
Anway, that's my $0.02. I thought about porting lcc to 2.11BSD ages ago,
but I've never had the time to do it.
Cheers,
Warren
