LLVM: llvm::VPIRBasicBlock Class Reference (original) (raw)
Public Member Functions
~VPIRBasicBlock () override
void
execute (VPTransformState *State) override
The method which generates the output IR instructions that correspond to this VPBasicBlock, thereby "executing" the VPlan.
clone () override
Clone the current block and it's recipes, without updating the operands of the cloned recipes.

cost (ElementCount VF, VPCostContext &Ctx) override
Return the cost of this VPBasicBlock.
Return the position of the first non-phi node recipe in the block.
phis ()
Returns an iterator range over the PHI-like recipes in the block.
Split current block at SplitAt by inserting a new block between the current block and its successors and moving all recipes starting at SplitAt to the new block.

void
print (raw_ostream &O, const Twine &Indent, VPSlotTracker &SlotTracker) const override
Print this VPBsicBlock to O, prefixing all lines with Indent.
If the block has multiple successors, return the branch recipe terminating the block.
Returns true if the block is exiting it's parent region.
clone () override
Clone the current block and it's recipes, without updating the operands of the cloned recipes.
virtual void
print (raw_ostream &O, const Twine &Indent, VPSlotTracker &SlotTracker) const=0
Print plain-text dump of this VPBlockBase to O, prefixing all lines with Indent.
void
print (raw_ostream &O) const

virtual VPBlockBase *
clone ()=0
Clone the current block and it's recipes without updating the operands of the cloned recipes, including all blocks in the single-entry single-exit region for VPRegionBlocks.
A special type of VPBasicBlock that wraps an existing IR basic block.
Recipes of the block get added before the first non-phi instruction in the wrapped block. Note: At the moment, VPIRBasicBlock can only be used to wrap VPlan's preheader block.
