+
+{-
+This module implements a simple common subexpression elimination
+ for gfc grammars, to factor out shared subterms in lin rules.
+It works in three phases: 
+
+  (1) collectSubterms collects recursively all subterms of forms table and (P x..y)
+      from lin definitions (experience shows that only these forms
+      tend to get shared) and counts how many times they occur
+  (2) addSubexpConsts takes those subterms t that occur more than once
+      and creates definitions of form "oper A''n = t" where n is a
+      fresh number; notice that we assume no ids of this form are in
+      scope otherwise
+  (3) elimSubtermsMod goes through lins and the created opers by replacing largest
+      possible subterms by the newly created identifiers
+
+The optimization is invoked in gf by the flag i -subs.
+
+If an application does not support GFC opers, the effect of this
+optimization can be undone by the function unSubelimCanon.
+
+The function unSubelimCanon can be used to diagnostisize how much
+cse is possible in the grammar. It is used by the flag pg -printer=subs.
