Looking for a PD 56000 assembler

Does anyone have a version of gnu-as tailored for the Motorola
DSP 56000/56001? If yes, is it reasonably input-compatible with the
assembler Motorola sells? And, by the way, is it possible to 'teach`
gcc to produce code that does use the parallel data moves these pro-
cessors know?
Thanks in advance for any hint. Just think you could save the (rela-
tive) sanity of a developer who doesn't quite like the platform he will
have to use (namely some PC-compatible). And, for the last question, which
might be silly since I didn't triple-read the GNU license, what's the
status for selling gnu-* produced code in an embedded system that has
not much display for a copyright and/or warranty notice ?
Again, thanks in advance,
bests regards,
Jean-Michel Pulfer

If you mean non-Gnu code compiled with a Gnu compiler, the consensus of opinion seems to be that such compiled non-Gnu code belongs to you, not to the Gnu FSF. Since there's often differences of opinion on legal issues, I'll further point out that a large number of companies (the one I work for included) compile the software we develop and sell with GNU cc/g++ without fear that their/our vast investment will suddenly belong to the FSF. I suspect that if the FSF took someone to court and tried to claim that the non-Gnu software belonged to the FSF simply because it was compiled with Gnu tools, then the court would very likely regard that as unfair restraint of trade, regardless of interpretation of fine print. That's just my personal opinion, of course. Doug -- Doug Merritt doug@eris.berkeley.edu (ucbvax!eris!doug) or uunet.uu.net!crossck!dougm

Since it's also Richard Stallman's opinion that FSF has no more rights
to code compiled with gcc (or assembled with gas) than to text edited
by Emacs, you're clearly on safe ground. However, if you link with
Gnu libraries it's another story.

We did our own C++ library just to avoid that possibility, but I still have personal difficulty with that point. From a *technical* point of view, using a library shouldn't allow what amounts to confiscation of the software using the library. Interpretation of the *law* is quite another matter, of course, but perhaps the law needs to be amended. Our fine judicial and legislative system unfortunately tends to be quite clueless on technical issues. Doug -- Doug Merritt doug@eris.berkeley.edu (ucbvax!eris!doug) or uunet.uu.net!crossck!dougm

FSF is still trying to resolve the legal issues surrounding copylefted libriaries to address just this issue. From what I've read on gnu.announce, FSF doesn't want to restrain use of their libraries because of developers reluctance to use them because technically they would have to distribute their source code with their binaries. Also I'm working on a Motorola compatable assembler for the 56000. I'm going to port it to the SPARC. If any one is interested in beta-testing drop me e-mail and I'll get a binary to you. cheers

Followups are directed to gnu.misc.discuss; let's not take over
comp.dsp with this discussion.

Well, yes, it's radical; he's trying to construct a new world where
you can get the source to every program you have. But it isn't the
copyright that does this; it's the Gnu license. Basically, with any
software license, you are only permitted to use the software under
conditions of the license. The question then comes up: what happens
if you violate the licensing conditions? The text says your source
code becomes freely redistributable; a court might not accept that
and just make you pay a heavy damage assessment instead. Still, you
can't violate software licenses with impunity.
Actually, you have two options for code that includes or is derived
from Gnu code: make the source freely redistributable, or do not
distribute the program at all (you can keep it for your own use).
But the new library license relaxes the conditions; when it becomes
effective, you can use gnu libraries and have your program be proprietary
as long as you meet certain conditions (THERE IS NO FINAL DRAFT YET but,
roughly, you send your .o files, a Makefile, and the source+objects to
whatever Gnu library you use, and you may not prohibit your users from
using a debugger or doing reverse engineering to try to improve the
program).
Just to be clear on the original discussion: Stallman and FSF make no
claims to gcc output (or, for that matter, to g++ output except that
libg++ is their code -- replace libg++ and the code is entirely yours).
