> Since the major refactoring of the existing recompiler in SYSTEMML-2072 (common code path), the explain recompile_hops flag returns misleading output. Specifically, during recompilation, the recompiler creates and updates a deep copy of the HOP DAG but the explain output shows the old (not updated) DAG.
