Public Attributes inherited from Halide::Internal::IRNode
RefCount	ref_count
	These classes are all managed with intrusive reference counting, so we also track a reference count.
IRNodeType	node_type
	Each IR node subclass has a unique identifier.

Additional Inherited Members
Public Member Functions inherited from Halide::Internal::ExprNode< Variable >
void	accept (IRVisitor *v) const override
	We use the visitor pattern to traverse IR nodes throughout the compiler, so we have a virtual accept method which accepts visitors.
