question about gcc

[Paul Albrecht]

Is there some reason gcc hasn't been or can't be enhanced to provide output for a cross-referencing
programs?

No reason why it can't be, and the reason it hasn't is that
no one has done it. Actually strictly you don't mean gcc
here, you are referring to particular front ends, since
the notion of referencing is somewhat language dependent.
So probably you are thinking of C and/or C++. Note that
GNAT, the Ada front end, does indeed output full
information for xref purposes, in the form of ali
files (it would indeed be nice if the C++ compiler
would generate something similar!)

I took a swipe at the c front end and have cross-referenced linux and gcc using my hacked gcc. I'd
like to get some feedback from the gcc community. You can check out my results at my web site

FYI, there are a number of tools available for producing 
cross-referencing info.  See for instance
     http://www.gnu.org/software/global/links.html
and try looking at the up-link to global itself also.  I found this by 
searching on the GNU web site.  I've never used global myself.

I'm not really so much interested in particular cross-referencing programs as I am interested in
whether the gcc community has considered providing compiler output to cross-referencing programs via
a front end option.

question about GCC

[manal habib]

Hi,

I am new into the field of coding, and I am wandering if I can get
some help on how to use the GCC? I have a mac version 10.5.8.   Should
I just copy one of the image folders to make computer?  how can use
it?

Thank you very much

This is not the right mailing list for questions about using gcc,
please ask on gcc-help@gcc.gnu.org instead.

I can't believe it someone actually bothers to send this message. 
A "Webster's" revised dictionary from 1913 that labels the word
as obsolete is a pretty pathetic source!

If you bother to look this up in a decent source (OED II volume XVIII, I 
just lugged the 1000 page volume from the library :-), you will find that
the last recorded use of this word is in 1659.

Shall we write the OED and tell them they should renovate this word and
create a quote for 2002 from the gcc@gnu.org list :-)

question about gcc

[marc.poulhies]

Hi,
I'm sorry if this question should not be asked to this email, but i tried to
read some doc but don'r really know which one i should use. I tried the gcc
manual and took a look at the "further readings" page, but i didnt found what i
was looking for... Here's my question:
I'm a student in computer sciences and i'm learning how compilers work. This
morning a student told that gcc, in fact, always traducts other languages to C,
as it was first designed for C and so can handle it very well.
I was suprised, but before telling him waht i thought, i wanted to have
something to show him (in the case he's wrong).
My readings gave me an answer about c++, but what about other languages?

Thanks ;)

Marc

PS: if this is really not the good email to ask, can you tell me where i can ask
this?

Re: question about gcc

[Andrea Bocci]

Hi Marc,
I'm no gcc expert, but from the little I know, compiling with gcc (at least 
for java, ada, fortran 77 and probably the gpc pascal port) goes like this:

.) the code is read, and compiled it into an abstract language, be it 
SIMPLE trees or RTL, by the frontend
.) optimizations are done on SIMPLE trees
.) trees are lowered to RTL
.) more optimizations are done ar RTL level by the backend
.) RTL are translated into assembler

then gcc calls the asembler (ie. GNU as) to make them into machine language 
(object file) and the linker (eg. GNU ld) to make the final program/library.

I hope ths was clear and correct enough.
If is there somoene more expert than me willingly to correct my ramblings, 
please do so :-)

traducts isn't a word in my language, so I might not understand your 
question.

What answer did your readings give you for C++?  If they say that C++ 
is translated into C, well that doesn't describe the GNU compiler.  g++ 
is a native C++ to assembly language compiler, just a GNU C is a C to 
assembly language compiler.  GNU C was written first, and GNU C++ came 
after it.  All the other languages that gcc supports are also compiled 
from their source language into trees, and from there into rtl and from 
there into assembly, as documented in the gcc manual:

    http://gcc.gnu.org/onlinedocs/gccint/Passes.html#Passes

If you've not read it, there is enough detail in there to keep you warm 
on a cold winter night, should you print it out first:

  http://gcc.gnu.org/onlinedocs/gccint/index.html

Hope this helps.

Sure it is. "Traduct" means to translate or to transfer.

$ dict -d web1913 traduct
2 definitions found

From Webster's Revised Unabridged Dictionary (1913) [web1913]:

  Traduct \Tra*duct"\, v. t. [L. traducere, traductum. See
     Traduce.]
     To derive or deduce; also, to transmit; to transfer. [Obs.]
     --Fotherby.

From Webster's Revised Unabridged Dictionary (1913) [web1913]:

  Traduct \Tra*duct"\, n.
     That which is traducted; that which is transferred; a
     translation. [Obs.] --Howell.

But Obs. is an abbreviation for obsolete so that is why he did not 
understand what the word is.

Also notice that a dictionary from 1913 is calling the word obsolete.
90 years later, the word is *really* obsolete.

English has a lot of vocabulary that came from French, but in many cases
the words have shifted meaning or are no longer used.

Hi,
I have just compile and install gcc 2.95.2. When I run the configure script 
of an application I want to compile, the script sys that he can guess the 
hsot type. I remember that I have to create a link to gcc with a given name, 
but I don't remember the name of this link.
Thanks in advance.

Question about GCC

[Vlasios Tsiatsis]

Hi, 

I hava a laptop with Windows95 an it and no C language on it.
I was thinking of building GCC on this machine but I don't know
if there is a distribution of GCC for Windows or DOS .

If there is where can I find it ?

thank you very much,

For DOS You can look for DJGPP:
	http://www.delorie.com/djgpp/

Works Ok also under Win95.

There is also related mailing list (and newsgroup comp.os.msdos.djgpp)
