Methods

¶VPBranchOnMaskRecipe(llvm::VPValue* BlockInMask)

Declared at: llvm/lib/Transforms/Vectorize/VPlan.h:1623

Parameters

llvm::VPValue* BlockInMask

¶static inline bool classof(const llvm::VPDef* D)

Description

Method to support type inquiry through isa, cast, and dyn_cast.

Declared at: llvm/lib/Transforms/Vectorize/VPlan.h:1630

Parameters

const llvm::VPDef* D

¶void execute(llvm::VPTransformState& State)

Description

Generate the extraction of the appropriate bit from the block mask and the conditional branch.

Declared at: llvm/lib/Transforms/Vectorize/VPlan.h:1636

Parameters

llvm::VPTransformState& State

¶llvm::VPValue* getMask() const

Description

Return the mask used by this recipe. Note that a full mask is represented by a nullptr.

Declared at: llvm/lib/Transforms/Vectorize/VPlan.h:1652

¶void print(llvm::raw_ostream& O,
           const llvm::Twine& Indent,
           llvm::VPSlotTracker& SlotTracker) const

Description

Print the recipe.

Declared at: llvm/lib/Transforms/Vectorize/VPlan.h:1640

Parameters

llvm::raw_ostream& O

const llvm::Twine& Indent

llvm::VPSlotTracker& SlotTracker

¶bool usesScalars(const llvm::VPValue* Op) const

Description

Returns true if the recipe uses scalars of operand \p Op.

Declared at: llvm/lib/Transforms/Vectorize/VPlan.h:1659

Parameters

const llvm::VPValue* Op
