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 am doing something about alias analysis for our compiler, I need the
field_id info for me.
I am not familiar with the gcc tree. any one know this?


thanks.
