Public Member Functions
	BaseStmtNode (IRNodeType t)
virtual Stmt	mutate_stmt (IRMutator *v) const =0
Public Member Functions inherited from Halide::Internal::IRNode
virtual void	accept (IRVisitor *v) const =0
	We use the visitor pattern to traverse IR nodes throughout the compiler, so we have a virtual accept method which accepts visitors.
	IRNode (IRNodeType t)
virtual	~IRNode ()=default

Additional Inherited Members
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.

Detailed Description

IR nodes are split into expressions and statements.

These are similar to expressions and statements in C - expressions represent some value and have some type (e.g. x + 3), and statements are side-effecting pieces of code that do not represent a value (e.g. assert(x > 3)) A base class for statement nodes. They have no properties or methods beyond base IR nodes for now.
