The subexpressions in the compiler are kept track of in a (balanced) tree to reduce the need for subexpressions and hence save much space in large rhs expressions (like when we have xxxxxxx occurrences of objects like f(x+1,x+1) in which each x+1 becomes a subexpression. The struct that controls this tree is COMPTREE.
