struct VPTransformState::CFGState

Declaration

struct VPTransformState::CFGState { /* full declaration omitted */ };

Description

Hold state information used when constructing the CFG of the output IR, traversing the VPBasicBlocks and generating corresponding IR BasicBlocks.

Declared at: llvm/lib/Transforms/Vectorize/VPlan.h:325

Member Variables

public llvm::VPBasicBlock* PrevVPBB = nullptr

The previous VPBasicBlock visited. Initially set to null.

public llvm::BasicBlock* PrevBB = nullptr

The previous IR BasicBlock created or used. Initially set to the new header BasicBlock.

public llvm::BasicBlock* ExitBB = nullptr

The last IR BasicBlock in the output IR. Set to the exit block of the vector loop.

public SmallDenseMap<llvm::VPBasicBlock*, llvm::BasicBlock*> VPBB2IRBB

A mapping of each VPBasicBlock to the corresponding BasicBlock. In case of replication, maps the BasicBlock of the last replica created.
