FYI, I've ftp'd the file(s) to build the Coactive gcc port, but have not yet built it. It's just another set of processor description files; i don't expect any problems. the beta release now uses the AS6811 assembler and ASLINKER (part of the distibution). I've atached the 'announce' information below: ----------------- cut here ------------------- Greetings, We are happy to announce a beta release of the 68HC11 port of the gnu gcc compiler version 2.5.8 done by Coactive Aesthetics. This is an upgrade from the alpha release we had done one year ago. Major changes in this release are: o Changed the machine description and target machine files to (correctly) generate QI and HI mode instructions. This means that the generic compiler code will work with no changes. It also means the 4 byte long support (using SI mode) would be easier to add. o The target machine file was changed to save and restore the "pseudo" registers when function calls are made. While this will increase code space usage, it does allow the optimizer to work correctly, and allows for function recursion (which would not work in the older version). o Updated some of the instructions in the machine description file to fix bugs, and added a function call for the multiply code. o It now uses the AS6811 assembler and ASLINK linker distributed by Alan R. Baldwin of Kent State University. I have modified the source (which is included in the release) to allow for globals symbols up to 32 bytes in length, and have changed the command line argument processing to allow the gcc front end to use these programs directly. The compiler still has the following "problems": o The is no librarian or support for linking with libraries. I have changed the linker to just ignore the -L and -l flags (if any) that are passed in. In looking at the relocatable file format, it shouldn't be that difficult to add support for libraries. o It doesn't handle floating point in any manner (any existence of floating point in the C code will crash the compiler). I decided not to take on the job of adding dummy instructions in the machine description file which would raise a somewhat reasonable error if floating point is seen. o Currently all longs are still TWO bytes. Since nobody that I have contacted attaches any importance to this, I doubt that it will ever be done. o I have not attempted to compile it on a MSDOS system. Given my experience in doing this with the alpha release, I doubt that I ever will try it again. If you have a 386/486 system, you may want to look into installing a free Unix system (Linux or 386bsd) to run the cross compiler. The port was written using the GCB11 Network Microcontroller board that is manufactured by Coactive Aesthetics. However, there is no assumptions and/or hardcode values within the compiler which would prevent the compiler from working on any 68HC11 board. More details on the can be found in the README file that is part of the distribution. The source for the 68HC11 specific files and the assembler/linker can be found at /pub/coactive/gcc-6811-beta.tar.gz on netcom.com (The ".gz" suffix indicates that it is in "gzip" format). You should also get the original distribution for gcc-2.5.8 from your favorite archive site. Any questions, bug reports, or porting comments/questions should be sent to gcc@coactive.com.

In my eyes, it's more important that we build something that works and less so of the exact details. I don't see the processor (or electronics) as the critical element of this project. (With that said, you other guys will be hard pressed to duplicate the software environment of the 68k with those *other* CPUs :) :). ) -------- 68HC000 schematics/update: Last week I transfered a front and back "pictures" of the 68HC000 board (two tiff files) to Robert Fridman for inclusion into the WWW server (Thanks, Robert). I had some problems getting the schematic into a form we could all work with, but, with some help from a colleague, I think we have it. -schematics. The schematic can now be retrieved through this mail server. The file is 68hc000-0.90.ps. Send help to Majordomo@coulomb.eng.ohio-state.edu for details. This postscript file outputs ten pages that when printed on 8.5x11 pager, and are taped together, form a D-sized drawing. There are some minor change that are not up-to-date on this schematic. (pin 16 of IC1 goes to ground, pin 15 of ic18 is grounded, and several sections of ic7, ic2, and ic3 where swapped to minimize wire path length). All simple things that I will have changed by the next version. If there is interest, I could make up some kind of a parts list etc... -board version. I deemed this version 0.90. The next version (by the end of the year) will replace the 74ls123a (ic10) with a Maxim supervisory ic (watch dog/battery switch over/reset generator), and include an interrupt priority encoder and a "heart beat" 100mS interrupt. This is a minor 3-4 chip change. -A companion board is in the works. -Real Time Executive for Military Systems (RTEMS) will become the kernel for the board. I'm almost ready to port it; I know what needs to be done but haven't done it yet. There are maybe 300-400 pages of documentation, 100 pages of C-code, and *lots* of flexibility. It will be "real-cool" once it comes together. -I expect spark timing will be the first thing implemented. Maybe yet this year. (ok, by spring?)
