Detailed Description

VPRecipeBase is a base class modeling a sequence of one or more output IR instructions.

VPRecipeBase owns the VPValues it defines through VPDef and is responsible for deleting its defined values. Single-value recipes must inherit from VPSingleDef instead of inheriting from both VPRecipeBase and VPValue separately.

Member Typedef Documentation

VPRecipeTy

using llvm::VPRecipeBase::VPRecipeTy

An enumeration for keeping track of the concrete subclass of VPRecipeBase that is actually instantiated.

Values of this enumeration are kept in the SubclassID field of the VPRecipeBase objects. They are used for concrete type identification.
