expr_hash_elt() [3/4]

expr_hash_elt::expr_hash_elt	(	struct hashable_expr *	orig,
		tree	orig_lhs )

Given a hashable_expr expression ORIG and an ORIG_LHS,
construct a hash table element.

expr_hash_elt() [4/4]

expr_hash_elt::expr_hash_elt

class expr_hash_elt &

)

Copy constructor for a hash table element.

~expr_hash_elt()

expr_hash_elt::~expr_hash_elt

(

)

Calls and PHIs have a variable number of arguments that are allocated
on the heap.  Thus we have to have a special dtor to release them.
