[Eric Methot]

Hello everyone,

Being a beginer at building front ends, I could use a little help
or a push in the right direction.

I am trying to do the following source to source transformation
inside the C compiler ( as a new front-end of course )

fun( a, g(2), p )

becomes:

struct { void* arg0, int arg1, int arg2, int *result } __desc = { myWrapper,
a, g(2), p };

I have tried to replace the action for building function calls
in the "primary : primari '(' exprlist ')' rule but ran in to many problems.

Am I on the right track?
Perhaps someone has already done this?

Also how can I create a global declaration while parsing a function
i.e. the declaration of my wrapper functions.  It seems that the nodes
get destroyed as soon as the parsing of the function is done.

By the way, when this compiler is done it will be realeased as a new
front-end
to gcc ( GPL ) along with the accompanying library ( GPL ).

Thanks,  Eric ;-)

Don't use ld to link, use gcc to link.

[pati (sent by Nabble.com)]

Hi , 

I am new to gcc and shell commands. I am trying to compile my code using gcc 3.3.2 provided with AMD Au1550 development CD. When I compile my code, I get an error message with undefined references to printf and other file i/o functions. I saw a couple of emails in the forum with the same problem.But, I think I have problem with the makefile I am using. I never wrote a make file before and I am using the makefile from the hello World example given with Au1550 CD. It works for that example, but it crashes with my code. 
I am attching the makefile with this email..

        $(RM) *.dis 
        $(RM) *.rec 
        $(RM) *.elf 
        $(RM) *~ 

I got the linnker directive from the hello world example.I assume the problem is with the linker and with the test.ld file from the hello world example. 

I used SDE toolchain before with the same code ,but a different make file but I never got this problem before. 

I really need help on this immediately. 

Thanks in advance - Pati

Start with:

(the referred to papers within that)

and the paper in the proceedings of the 2003 GCC Summit:

There is no easy answer to this question.  There is no easy place to get 
all of the info you want.  The info is in different places in different 
front ends and in different gcc versions.  You will have to spend quite 
a bit of time looking at gcc sources in order to be successful at 
modifying it.

Getting variable declarations isn't too hard.  They all have to do into 
the symbol table anyways, so the symbol represents a single place you 
can look for the info.  See for instance pushdecl in the C front end. 
Pretty much every variable declaration goes through this.  See also 
pushlevel and poplevel.  These maintain the BLOCK trees that hold the 
scoping info for variables.

The other of this, keeping track of operators, is much harder.  I don't 
think there is any single place you can hook in with current gcc for 
this info.  Maybe on the tree-ssa branch it is better.

There are extensive docs in the gcc/doc directory.  These docs aren't 
very readable, but they have a lot of useful info in them.  These docs 
are also available on the web site.

In coretypes.h in current sources, tree.h in older sources.  You will 
have to look at tree.h in either case.

I'm not sure what you mean here. 'ANSI style'? GCC does (AFAIK) support
K&R syntax C but I can't imagine you mean that - do you?

The suite of available functions depends more upon your system libraries
and headers. Yes, GCC does provide a number of '__builtin' functions but
these are mostly versions of common C library functions or low-level
stack frame operations. Details in the GCC manual, e.g.:

    http://gcc.gnu.org/onlinedocs/

This is a mailing list about the development of GCC.  GCC doesn't
