Alexandre Duret-Lutz	536e45b342	Arrange multops so that Boolean arguments come first. ... This helps recursive implication checks. Also order atomic propositions with strverscmp(). * src/ltlast/formula.hh (formula_ptr_less_than_multop, is_literal, atomic_prop_cmp): New. * src/ltlast/formula.cc (is_literal, atomic_prop_cmp): Implement them. * src/ltlast/multop.cc: Use formula_ptr_less_than_multop. * src/ltltest/isop.test, src/ltltest/ltlfilt.test, src/tgbatest/det.test, src/tgbatest/dstar.test, src/tgbatest/explicit.test, src/tgbatest/explpro2.test, src/tgbatest/explpro3.test, src/tgbatest/explprod.test, src/tgbatest/nondet.test, src/tgbatest/tripprod.test: Adjust tests. * NEWS: Mention the new order.	2013-09-26 17:14:58 +02:00
