¶llvm::Value* createTargetReduction(
    llvm::IRBuilderBase& B,
    const llvm::TargetTransformInfo* TTI,
    const llvm::RecurrenceDescriptor& Desc,
    llvm::Value* Src,
    llvm::PHINode* OrigPhi = nullptr)

Description

Create a generic target reduction using a recurrence descriptor \p Desc The target is queried to determine if intrinsics or shuffle sequences are required to implement the reduction. Fast-math-flags are propagated using the RecurrenceDescriptor.

Parameters

llvm::IRBuilderBase& B

const llvm::TargetTransformInfo* TTI

const llvm::RecurrenceDescriptor& Desc

llvm::Value* Src

llvm::PHINode* OrigPhi = nullptr
