CVSROOT: /cvs/ppl Module name: ppl Changes by: ericci@cs.unipr.it 2001-11-04 15:59:19

Modified files: src : Polyhedron.cc

Log message: In functions Polyhedron::update_constraints and Polyhedron::update_generators we only have a saturation matrix up-to-date: so, we must say that the other is not up-to-date. In function Polyhedron::assign_variable, if the transformation is not invertible, we must have the system of generators up-to-date, and then if the polyhedron is non-empty, we use the function GenSys::assign_variable to find the resulting polyhedron. so, we always modify the polyhedron (we do not modify the polyhedron if it is empty or if there are dimensional problems).
