示例1: loops
// If n0 is replaced by n1 in the substitution map. Will it cause a loop?
// i.e. will the dependency graph be an acyclic graph still.
// For example, if we have x = F(y,z,w), it would make the substitutionMap loop
// if there's already z = F(x).
bool SubstitutionMap::loops(const ASTNode& n0, const ASTNode& n1)
{
if (n0.GetKind() != SYMBOL)
return false; // sometimes this function is called with constants on the
// lhs.
if (n1.isConstant())
return false; // constants contain no variables. Can't loop.
// We are adding an edge FROM n0, so unless there is already an edge TO n0,
// there is no change it can loop. Unless adding this would add a TO and FROM
// edge.
if (rhs.find(n0) == rhs.end())
{
return vars.VarSeenInTerm(n0, n1);
}
if (n1.GetKind() == SYMBOL && dependsOn.find(n1) == dependsOn.end())
return false; // The rhs is a symbol and doesn't appear.
if (debug_substn)
