bool expr_elt_hasher::equal ( const value_type *  p1, const compare_type *  p2  )

inlinestatic

 This case should apply only when removing entries from the table.   

 FIXME tuples:
 We add stmts to a hash table and them modify them. To detect the case
 that we modify a stmt and then search for it, we assume that the hash
 is always modified by that change.
 We have to fully check why this doesn't happen on trunk or rewrite
 this in a more  reliable (and easier to understand) way.  

 In case of a collision, both RHS have to be identical and have the
 same VUSE operands.   

     Note that STMT1 and/or STMT2 may be NULL.
