Does anyone know which field in the tree node is used for actual alignment?
I am particularly interested in a scalar field in a record which has a 
requested halfword alignment but has been positioned on a 32 bit boundary.

For a simplistic example:

   struct {
      int x __attribute__ ((packed align(2)));
      } s1;

How can I tell if x will be position on a halfword boundary or a word boundary?
In addition, I would like to be able to tell prior to rtl generation.  If it is
important, I am compiling for solaris2.3.
Thanks in advance.
