companion processor

[Uno]

Is there any notion of a potential "companion processor" in standard C?
I did a search for the term in n1256.pdf and got nothing.

Almost certainly it would not exist in the standard itself. The
processors that C first imagined were Randian clickers.

Along the way, it becomes very popular and finds that it needs to have
opinions on things like IEEE754. Everyone I talk to says that both C
and Fortran got this wrong, but I have yet to figure out why.

Is it maybe one of those things that was never written because everyone
(in the C community) wanted to have it be the lingua franca.

Or maybe some non-binding agreement?

I've never heard of it before. My first guess would be that you mean
"coprocessor", as in Intel 80387 (reinforced by the later mention of
IEEE754). And the answer would be that C doesn't care about how work is
divided between chips in a machine.

But I really don't know how to make sense of your question. I think you'll
have to define "companion processor" for us. It may be a term that only
Fortran programmers know.

Yes, it is a Fortran only term. A Fortran processor is anything
that can translate the Fortran language into some that gets an
answer. Most people associate a Fortran processor with a Fortran
compiler. Fortran has a feature known as the ISO C BINDING, which
as the name suggests tries to define an inter-language interface
between Fortran and ISO C. In the Fortran standard, the term
companion processor is the C processor (ie., the C compiler).

Having read OP's original post, it appears to be a rambling
free association of terms from the C and Fortran standard
with a vague reference to IEEE 754.

With the exception that it doesn't need to be standard C.

I'd just like to point out the ungrammatical nature of steve's last
sentence. Furthermore, I think his point-of-view puerile with respect
to computers that take down a job together, co-processing.

Since he knows more and comments more about the interaction of my
favorite syntaxes, he can insult me all day long.

I still don't understand why "Uno" has to change nyms every so often to
avoid killfiles. You'd think he'd be happier if the people who think he's
a troll or an idiot weren't reading his posts.

and since you post useful source, just go ahead and add an insult. I
think of you like Tim P., one of russian professors. He may have
sounded mean on the internet, but he was 5'6".

I'll bet dollars to donuts that you and steve can't be 12 feet tall.

No, you british turd.

It's time you did a CBFalconer and just died.

And what do you think people who might have known Chuck will think on
reading that?

Please show a bit of commonsense.

 

[Tom St Denis]

Oh shit. Chuck didn't pass away did he?

I'm sorry to hear that.

Even if he hadn't [I don't know one way or the other but it sounds
familiar] you don't wish for peoples death. I suspect "Uno" refers to
the number of surviving brain cells in his head...

You know, this pretty much summarizes your problem. You're not just sometimes
mistaken; you're an aggressive seeker after nonsense, who will go to great
lengths to come up with ludicrous things to believe for no reason other than
that they contradict reality.

Hint: While it's true that I've been in Britain a couple of times, it's not
even in the top three of countries I've spent time in.

I doubt that this "Uno" character has any real information.

There was some speculation last year that CBFalconer had died.
At the time, jacob navia was kind enough to phone him and confirm
that he was ok. jacob, I wonder if you could try again, just to
make sure, and report back. I'd be grateful, and I'm sure plenty
of others would as well.

(I've tried dropping Chuck an e-mail; no response yet, but too
soon to worry.)

Every time you land on my thread, it's a loss for me. So Chuck still
lives. Thank goodness he's too sick to perform the same function you do.

What brand of eurotrash are you?

it is sad that someone that spend time for help people,
has to return these hard words for the same group.
the answer to the question of OP for print little double numbers
with printf is in the faq and in the book
it is right

one stupid language or C language or all the world knowing
is less than one human

Chuch may have a colostomy bag in real life, but in clc, he was an asshole.

Anybody who wants to enter my killfile can respond with something
snarky. I'll remind respondents that I'm OP and that I did not want
Seebach shitting on my thread.

I don't mean you, seebs. I'd like to know from you how you would
compare and contrast yourself and chuck.

Please, please, please killfile me. Will that do?
