[pups] gcc-.3.4.6 for pdp11

[Bill Cunningham]

    Does anyone know how to compile gcc-3.4.6 for the pdp11? I use
the --target=pdp11 switch and the compiler runs for awhile then breaks. The
output says it's bulding for a pdp11-unknown something so there maybe
something I'm not using.

Hello!
Bill? What are you building this on? If it's a Linux host, then check
your sources. They are required to provide them. I should also add
that the embedded tool providers should have notes on those steps. Oh
and while your at it, you could show us the complete listing of your
attempts.

Building gcc as a cross compiler can be quite challenging.

Dan Kegel has put together a set of scripts which largely automate the 
process
and which can be found at http://www.kegel.com/crosstool/

Unfortunately (but not surprisingly) pdp11 is not on of the targets 
supported
by crosstool, but you might still find it useful as an illustration of 
the kinds of
things that may need to be done.

Before people devote too much effort to flogging a dead horse, I,
too, have recently tried to build a gcc cross-compiler for the
PDP-11 with no success.  I have not seen a version that worked
since GCC 2.something.  It is possible that changes to GCC have
broken the PDP-11 code and that no one is keeping it up.  I would
love to hear otherwise if anyone has successfully built a pdp-11
cross compiler using anything vaguely current.

And there's another issue: *which* PDP11?  I have a MINC-11 that was 
upgraded with an 11/23 CPU, as many were.  I managed to get my hands on 
the original MINC software, and it would not run.  It's been a while 
since I did that so I don't remember the exact instruction on which it 
choked (with an illegal instruction trap).  But I dropped in an 11/03 
CPU and all ran fine.  I found a helpful matrix in one of the DEC 
handbooks that outlines just which instructions were changed between 
several of the Qbus processors, anyway. 

Imagine the number of compiler switches....  -- Ian

The GCC team has dropped a lot of older and "less interesting"
(in their minds) platforms from active support (and made the thing
too slow for anything but modern processors, but that's another
rant).

What would be wrong with using gcc 2.95 or older?

Nick.

Long ago I saved this post by Michael Gschwind relating to patching  
gcc 2.1:

I may be able to offer help with the PDP-11 target in GCC and/or
binutils.  Email me for details.
