blocksOnly()

template<typename BlockTy , typename T >

static auto llvm::VPBlockUtils::blocksOnly ( const T &  Range )

inlinestatic

Return an iterator range over Range which only includes BlockTy blocks.

The accesses are casted to BlockTy.

Definition at line 2555 of file VPlan.h.

References llvm::Block, llvm::Filter, llvm::make_filter_range(), and llvm::map_range().

connectBlocks()

static void llvm::VPBlockUtils::connectBlocks ( VPBlockBase *  From, VPBlockBase *  To  )

inlinestatic

Connect VPBlockBases From and To bi-directionally.

Append To to the successors of From and From to the predecessors of To. Both VPBlockBases must have the same parent, which can be null. Both VPBlockBases can be already connected to other VPBlockBases.

disconnectBlocks()

static void llvm::VPBlockUtils::disconnectBlocks ( VPBlockBase *  From, VPBlockBase *  To  )

inlinestatic

Disconnect VPBlockBases From and To bi-directionally.

Remove To from the successors of From and From from the predecessors of To.

Definition at line 2546 of file VPlan.h.

References assert(), and From.

insertBlockAfter()

static void llvm::VPBlockUtils::insertBlockAfter ( VPBlockBase *  NewBlock, VPBlockBase *  BlockPtr  )

inlinestatic

Insert disconnected VPBlockBase NewBlock after BlockPtr.

Add NewBlock as successor of BlockPtr and BlockPtr as predecessor of NewBlock, and propagate BlockPtr parent to NewBlock. BlockPtr's successors are moved from BlockPtr to NewBlock. NewBlock must have neither successors nor predecessors.

insertTwoBlocksAfter()

static void llvm::VPBlockUtils::insertTwoBlocksAfter ( VPBlockBase *  IfTrue, VPBlockBase *  IfFalse, VPBlockBase *  BlockPtr  )

inlinestatic

Insert disconnected VPBlockBases IfTrue and IfFalse after BlockPtr.

Add IfTrue and IfFalse as succesors of BlockPtr and BlockPtr as predecessor of IfTrue and IfFalse. Propagate BlockPtr parent to IfTrue and IfFalse. BlockPtr must have no successors and IfTrue and IfFalse must have neither successors nor predecessors.
