In the reverse mode,
VisitWithExplicitNoDfDx(const Stmt* S)
visitsS
while pushingnullptr
to thedfdx()
stack. This is exactly the behaviour we get when callingVisit(const Stmt* S, Expr* dfdS = nullptr)
with a single parameter. In other words,VisitWithExplicitNoDfDx(S)
is the same asVisit(S)
. This PR removes this function.
