I totally missed it. Thank you for informing me.
I tested it with a dummy parameter. The dummy parameter taking the
place of the this pointer. It worked perfectly.

Sorry about the fwd in the description.
This is my implementation:
fnDeclType = build_function_type_array(integer_type_node,
argVect.NumOfItems, parmTypes);
tree fnDecl = build_fn_decl(identifier->Str, fnDeclType);
DECL_EXTERNAL(fnDecl) = 1;

I am discovering the awesome world of GCC internals. I managed to
develop a basic front end. It can call internal and external functions
and link with standard libraries. All is good.
The hunger for more does not end. I want to call c++ libraries and
interact with c++ objects.

Hi!

Happily, I found the answer of my question. Now, I'm having other

Hello all,
I am involved with a GCC port where i have to add fixed point support to C
based on the fixed point extension of DSP-C specification.
So intially i thought that i will typedef long or short to support the new data
type.
But for my hardware the fixed point registers are 48 bit long.

we should ensure *p will never exceed the length, otherwilse it will
fail to do alias analysis.

Hi all:
for the following statement, how can I get the field_id info for
the structure member
struct{
int a;
int b;
} pair;
int main()
{
int * p = &pair.a;
}
It seems that we can't get the field_id info because of address taken
operator. it treats the "&pair.a" as "&pair + ofset of a".

I think that you should take a look at the GCC front end HOWTO. Some parts of
it are out of date but most of it is quite useful. Studing other front ends
is also helpfull

There is no option that does what you want. This is a deliberate,
albeit controversial, design decision which we are not presently
interested in debating.
If you are writing a back end, consider using the existing, well-
understood machinery for porting GCC to a new architecture. If you go
