Classes

class  Halide::Internal::Scope< T >
 A common pattern when traversing Halide IR is that you need to keep track of stuff when you find a Let or a LetStmt, and that it should hide previous values with the same name until you leave the Let or LetStmt nodes This class helps with that. More...
 
struct  Halide::Internal::ModulusRemainder
 The result of modulus_remainder analysis. More...
 

Namespaces

 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.

ModulusRemainder Halide::Internal::modulus_remainder (const Expr &e)
 For things like alignment analysis, often it's helpful to know if an integer expression is some multiple of a constant plus some other constant. More...
 
ModulusRemainder Halide::Internal::modulus_remainder (const Expr &e, const Scope< ModulusRemainder > &scope)
 If we have alignment information about external variables, we can let the analysis know about that using this version of modulus_remainder: More...
