Generic and Gimple in gcc4.6

[charfi asma <charfiasma@xxxxxxxx>]

Hello,

I am interested in Generic and Gimple IR dumped with g++ file.cpp 
-fdump-tree-all
I test this command with a cpp file that only contains int x=2
but the dumped Generic (file.cpp.001t.tu)  is so strange, more than 7000 line of 
code for only one instruction !!
however the Gimple is correct: 

int main() ()
{
  int D.1694;
  {
    int x;

    x = 5;
  }
  D.1694 = 0;
  return D.1694;
}

Any explanation ??

Thanks 

Asma
