Hello Phil,

you will find answer to your question here :
http://gcc.gnu.org/ml/gcc-help/2010-11/msg00090.html
Ian suggest that I see the c++ front end and do the same, but it was a little 
diffucult for me ;) 

that's why I do it manually : I added the instance param in the CALL_EXPR tree 
code.
you find also in the post my gimple and the cp gimple they are almost the same.

Hope it helps.

Asma

Hey

Thanks for those links i am a little confused still not sure if i've
done everything right.

Say for example i wanted to implment this:

int main() ()
{
  int D.1710;

  {
    struct myClass test;

    myClass::set_values (&test, 3, 4);
    D.1710 = 0;
    return D.1710;
  }
  D.1710 = 0;
  return D.1710;
}


void myClass::set_values(int, int) (struct myClass * const this, int a, int b)
{
  this->x = a;
  this->y = b;
}

Which is the gimple dump of:

class myClass
{
  int x, y;

  public:
    void set_values (int, int);
};

void myClass::set_values (int a, int b)
{
  x = a;
  y = b;
}

int main ()
{
  myClass test;

  test.set_values (3,4);

  return 0;
}


I make a RECORD_TYPE called myClass and having FIELD_DECLS for x and y.

set_values = FUNCTION_DECL....
Then i use TYPE_METHODS(myClass) = set_values

Then i dont understand how i call the method not sure how i use the
build_call_expr to do that.
