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::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...
