counter updated each time we create a new (unique) formula. Doing so saves a lot of memory during the translation of the ltlcounter formulae, because the formulae are quite big and storing a string representation of each formula on its node was a bad idea. For instance with n=12, the translation now uses 40MB where it used 290MB. (Note: in both cases, 20MB is being used by the BDD cache.) * src/ltlast/formula.hh (hash_key_): Rename as ... (count_): ... this. (hash): Adjust. (max_count): New static variable to count the number of formulae created. (formula): Update max_count and set count_. (dump): Make it a virtual pure method. (set_key_): Remove. (formula_ptr_less_than): Speed up and return false when the two formula pointer are equal. * src/ltlast/formula.cc (set_key_, dump): Remove. * src/ltlast/atomic_prop.cc, src/ltlast/atomic_prop.hh, src/ltlast/automatop.cc, src/ltlast/automatop.hh, src/ltlast/binop.cc, src/ltlast/binop.hh, src/ltlast/constant.cc, src/ltlast/constant.hh, src/ltlast/multop.cc, src/ltlast/multop.hh, src/ltlast/unop.cc, src/ltlast/unop.hh: Empty the constructor (do not precompute the dump_ anymore), and add a dump() implementation.f2be64dd
