Detailed Description

   An expression that appears in a constraint.

Field Documentation

HOST_WIDE_INT constraint_expr::offset 
     Offset, in bits, of this constraint from the beginning of
     variables it ends up referring to.

     IOW, in a deref constraint, we would deref, get the result set,
     then add OFFSET to each member.
