Detailed Description

Helper class for constructing bundles of MachineInstrs.

MIBundleBuilder can create a bundle from scratch by inserting new MachineInstrs one at a time, or it can create a bundle from a sequence of existing MachineInstrs in a basic block.

Constructor & Destructor Documentation

llvm::MIBundleBuilder::MIBundleBuilder ( MachineBasicBlock BB,
MachineBasicBlock::iterator  Pos 
)
inline

Create an MIBundleBuilder that inserts instructions into a new bundle in BB above the bundle or instruction at Pos.

Definition at line 435 of file MachineInstrBuilder.h.

llvm::MIBundleBuilder::MIBundleBuilder ( MachineBasicBlock BB,
MachineBasicBlock::iterator  B,
MachineBasicBlock::iterator  E 
)
inline

Create a bundle from the sequence of instructions between B and E.

Definition at line 440 of file MachineInstrBuilder.h.

References llvm::MachineInstr::bundleWithPred(), and llvm::AArch64CC::MI.

llvm::MIBundleBuilder::MIBundleBuilder ( MachineInstr MI)
inlineexplicit

Create an MIBundleBuilder representing an existing instruction or bundle that has MI as its head.

Definition at line 455 of file MachineInstrBuilder.h.

Member Function Documentation

MIBundleBuilder& llvm::MIBundleBuilder::append ( MachineInstr MI)
inline

Insert MI into MBB by appending it to the instructions in the bundle.

MI will become the last instruction in the bundle.

Definition at line 501 of file MachineInstrBuilder.h.

References end(), and insert().

Referenced by insertDelayFiller().

MachineBasicBlock::instr_iterator llvm::MIBundleBuilder::begin ( ) const
inline

Return an iterator to the first bundled instruction.

Definition at line 466 of file MachineInstrBuilder.h.

Referenced by prepend().

bool llvm::MIBundleBuilder::empty ( ) const
inline

Return true if no instructions have been inserted in this bundle yet.

Empty bundles aren't representable in a MachineBasicBlock.

MachineBasicBlock::instr_iterator llvm::MIBundleBuilder::end ( ) const
inline

Return an iterator beyond the last bundled instruction.

Definition at line 469 of file MachineInstrBuilder.h.

Referenced by append().

MachineBasicBlock& llvm::MIBundleBuilder::getMBB ( ) const
inline

Return a reference to the basic block containing this bundle.

Definition at line 459 of file MachineInstrBuilder.h.

MIBundleBuilder& llvm::MIBundleBuilder::insert ( MachineBasicBlock::instr_iterator  I,
MachineInstr MI 
)
inline
MIBundleBuilder& llvm::MIBundleBuilder::prepend ( MachineInstr MI)
inline

Insert MI into MBB by prepending it to the instructions in the bundle.

MI will become the first instruction in the bundle.

Definition at line 495 of file MachineInstrBuilder.h.
