I have done some more searching for DLX C compilers, and offer these further
notes. The prose is a bit choppy, but the links are very nice.
Generally, you can probably find a way to generate GCC in an older simpler
fashion with a DLX back end, or GCC in a new fashion (more complex because of
C++ embellishments) with the DLX format.
There are a few references to commercial sites here (I have tried to note that
well enough so you can avoid them if you want).
As you will be able to see I can not quite resolve a location for DLX
attachments to GCC 2.8.x. Help is solicited for that. I will continue to try
to resolve the "dcc" thing I mention previously. If it is real, it may be a

Go into this directory, and do the following:

(but I find no string dlx in GNU GCC 2.8.1 down loaded from MIT 9/26/98)
This site may still be of interest to anyone wanting to use a simpler GCC of
A higher level README file indicates
This directory contains two things: a C compiler for DLX, and a
simulator for DLX. Have a look in the file dlx/daxpy.c for an
example of how this software is used.
See also dlx/man/dlxcc.catman for further info on dlxcc. The
documentation for dlxsim is in dlx/man/manual.dvi; to read this do the
following on an X terminal:
The sample program daxpy.c is C code not just inline assemler.

you may need to regen GCC for your platform.

I have received references to
Their GNUPro package is not free, so this is not exactly responsive to the
original poster's request.
However the package may relate to some institutional interests.
I have not yet learned if the package has been or can be configured to DLX.

I personally down loaded a GCC 2.8.x tar file and expanded it.
Interestingly I find no occurrence of the string 'dlx' in the expanded
material. I must be missing something.
The standard GCC (atleast the most recent one) may not have the DLX back-end

sites pointed to by the linked university pages, are commercial in
There is plenty of DLX material here, for example, from here you can find
a gccdlx made with GNU C 2.7.x at University of Minnesota
I have not chased that link yet, It may well be the best to look to for use of
the most recent GCC.
Also of more general reference is a link from the mkp page to

Oodles of fun stuff there.
Addendum on DLX
For those doing further searching on DLX please note that on the net
the search argument "dlx" is likely to find
DLX for P&H, and GNU
DLX of Linux distribution
DLX a substring in a name for components

IT is hard to filters these out, so you have to patiently view
I have one reference to a "dcc" which may be a DLX C compiler.
I have not yet resolved this. The argument "dcc" can prompt search engines to
return refrences to certain decompiler work at academic institutions, which
also has to be patiently by-passed.
