Hi Arnaud,
This is all nice and well and I'm sure you're having lots of fun with
these discussions, but gcc@gcc.gnu.org is NOT an appropriate
list for such discussions, so please move this discussion elsewhere,
there are people on this list who would rather not receive these unrelated
emails, th
The purpose of this discussion (whoa, 30+ thread in the gcc mailing
list for being b@d@ss) is that I will learn the sufficient amount of
things so I WON'T "commit the crime".
I would like to be clear from the start so I won't have any problems;

You missed the part about "(and is used in practice)".
This terminology is superficial. Looks carelessly written. A tool with
either one user or one million users would equally fit the definition.

Hi all,
what I basically want to do is a kind of "MMIX", an abstract machine

Hi Andrew
AFAICS GPL,v3+ restricts my freedom... I thought that its purpose was
to protect my freedom.
No. I don't simply want to pile on after everything that has been
said, but this is a common misconception. It isn't the purpose of the

Hi all,
I believe in free software as a contribution to a better society and
believe in the use of licenses such as GPLv3 to promote software sharing
by providing a software commons that can be used by those who will

Hi Robert
One principle that can be applied is that if you have a program in
two pieces, then they are independent if either of them can be used
(and is used in practice) with other programs. But if the two pieces
can only work together, that seems part of the same program. I tried
to get this p

There are not many lawyers in Greece that deal with open-source licenses.
The legal issue here has nothing whatsoever to do with open-source
licenses: the exact same issue comes up with proprietary licenses and
that, in fact, is where most of the precedents come from.
Hi Richard
Would these solve my problem?
No, not as long as it's *your* machine. It would need to be a machine
designed by a third-party that's completely independent of you.
I would like to follow the approach of let's say MMIX (a virtual
architecture).

Hi Richard,
If you want to argue that, I'd suggest you not do so on this email list:
it's not going to be well-received.

is not my saying, just that my army colleagues wouldn't shake hands

Hi Richard,
If you have a legal question, you should ask an attorney who specializes
in copyright law as it applies to computer software. Do not rely on
anything you get as a response to your question online.

Hi Robert,
There are two comfortable ways to conform to the GPL.
a) make all your own stuff GPL'ed
b) write proprietary code, that links in only modules with
the standard library exception.
I guess I'm naturally going for b), that was the original intention.
Anything else, and you are pret
Hi,
You can't expect to get legal advice from a list like this, and if
you do get advice, you can't trust it. You have to consult an attorney
to evaluate issues like this, and even then you can't get
guaranteed definitive advice. Copyright issues are complex,

Dear all,
this is a repeat of an email to licens...@fsf.org; unfortunately I

Look at the cgraph (.000i.cgraph) dump.

Hi there
i'm looking for a way to emit (dump) complete global and local symbol table

Hi there
i have went through some of the GIMPLE stuff (mostly went through the GCCSummit
2003 paper). I think i have some reservations on the structure and semantics
of GIMPLE. Most of my compiler experience comes from interactions with the

Hi there
i'm in the process of coding a GCC backend for a certain RISC-like architecture.
Its register architecture consists of an integer register file (32 regs) and two
additional hard regs that should be programmer visible. Accesses to these hard
regs are also emitted related to certain RTL pat
Hi there
is anyone working on a DLX backend for gcc-3.x?
I recall of a DLX backend for dlx-2.7.2.x, but this backend cannot be properly
integrated in a recent gcc (3.0 and above).
A "clean" DLX backend would be a very good start point for developing backends
for different RISC-based machines (fi
Dear Diego,
is the newest version of your pass (including the June 01 modifications at
gcc-patches) applicable to all statements in a basic block and not only to the
conditionals?

version two things happen:

If you visit the following:
http://gcc.gnu.org/gcc-4.0/changes.html
a reference is found to value range propagation pass. However, $GCCHOME/gcc
directory doesn't contain the required files (e.g. tree-vrp.c).
Is this an addition for a scheduled (pre)release or i just can't find it in the

Hi there
does the 4.0.1 RC1 include the value range propagation (VRP) ssa-based pass

If not what is the VRP status at the CVS for the C language? Is it basically

Thanks Daniel!
actually my 2 messages were send back-to-back. I have just read both your
responses and I can see that i could use stringify approach to force the
assembly output of GCC to what I want.

I was wondering...
why not support asm templates THAT ARE NOT string constants??? And I
mean for static compilation cases only.
For example:
asm(instrx $%d, $%d\n",src1,src2 : "=r" (var1) : "r" (var2));
I assume printf-like formating.
