Classes
struct	Halide::Internal::IRNode
	The abstract base classes for a node in the Halide IR. More...
struct	Halide::Internal::BaseStmtNode
	IR nodes are split into expressions and statements. More...
struct	Halide::Internal::BaseExprNode
	A base class for expression nodes. More...
struct	Halide::Internal::ExprNode< T >
	We use the "curiously recurring template pattern" to avoid duplicated code in the IR Nodes. More...
struct	Halide::Internal::StmtNode< T >
struct	Halide::Internal::IRHandle
	IR nodes are passed around opaque handles to them. More...
struct	Halide::Internal::IntImm
	Integer constants. More...
struct	Halide::Internal::UIntImm
	Unsigned integer constants. More...
struct	Halide::Internal::FloatImm
	Floating point constants. More...
struct	Halide::Internal::StringImm
	String constants. More...
struct	Halide::Expr
	A fragment of Halide syntax. More...
struct	Halide::ExprCompare
	This lets you use an Expr as a key in a map of the form map<Expr, Foo, ExprCompare> More...
struct	Halide::Range
	A single-dimensional span. More...
struct	Halide::Internal::Stmt
	A reference-counted handle to a statement node. More...
struct	Halide::Internal::Stmt::Compare
	This lets you use a Stmt as a key in a map of the form map<Stmt, Foo, Stmt::Compare> More...

Namespaces
namespace	Halide
	This file defines the class FunctionDAG, which is our representation of a Halide pipeline, and contains methods to using Halide's bounds tools to query properties of it.

Typedefs
typedef std::vector< Range >	Halide::Region
	A multi-dimensional box.
