Classes
struct	Halide::Internal::Cast
	The actual IR nodes begin here. More...
struct	Halide::Internal::Reinterpret

struct	Halide::Internal::Min
	The lesser of two values. More...
struct	Halide::Internal::Max
	The greater of two values. More...
struct	Halide::Internal::EQ
	Is the first expression equal to the second. More...
struct	Halide::Internal::NE
	Is the first expression not equal to the second. More...
struct	Halide::Internal::LT
	Is the first expression less than the second. More...
struct	Halide::Internal::LE
	Is the first expression less than or equal to the second. More...
struct	Halide::Internal::GT
	Is the first expression greater than the second. More...
struct	Halide::Internal::GE
	Is the first expression greater than or equal to the second. More...
struct	Halide::Internal::And
	Logical and - are both expressions true. More...
struct	Halide::Internal::Or
	Logical or - is at least one of the expression true. More...
struct	Halide::Internal::Not
	Logical not - true if the expression false. More...
struct	Halide::Internal::Select
	A ternary operator. More...
struct	Halide::Internal::Load
	Load a value from a named symbol if predicate is true. More...

	A linear ramp vector node. More...
struct	Halide::Internal::Broadcast
	A vector with 'lanes' elements, in which every element is 'value'. More...
struct	Halide::Internal::Let
	A let expression, like you might find in a functional language. More...
struct	Halide::Internal::LetStmt
	The statement form of a let node. More...
struct	Halide::Internal::AssertStmt
	If the 'condition' is false, then evaluate and return the message, which should be a call to an error function. More...
struct	Halide::Internal::ProducerConsumer
	This node is a helpful annotation to do with permissions. More...
struct	Halide::Internal::Store
	Store a 'value' to the buffer called 'name' at a given 'index' if 'predicate' is true. More...

	A pair of statements executed concurrently. More...
struct	Halide::Internal::IfThenElse
	An if-then-else block. More...
struct	Halide::Internal::Evaluate
	Evaluate and discard an expression, presumably because it has some side-effect. More...

	A function call. More...
struct	Halide::Internal::Variable
	A named variable. More...
struct	Halide::Internal::For

	Represent a multi-dimensional region of a Func or an ImageParam that needs to be prefetched. More...
struct	Halide::Internal::HoistedStorage
	Represents a location where storage will be hoisted to for a Func / Realize node with a given name. More...
struct	Halide::Internal::Atomic
	Lock all the Store nodes in the body statement. More...
struct	Halide::Internal::VectorReduce
	Horizontally reduce a vector to a scalar or narrower vector using the given commutative and associative binary operator. More...
