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 424 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.

[inline, explicit]

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

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 490 of file MachineInstrBuilder.h.

References end(), and insert().

MachineBasicBlock::instr_iterator llvm::MIBundleBuilder::begin

(

)

const [inline]

Return an iterator to the first bundled instruction.

Definition at line 455 of file MachineInstrBuilder.h.

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 458 of file MachineInstrBuilder.h.

MachineBasicBlock& llvm::MIBundleBuilder::getMBB

(

)

const [inline]

Return a reference to the basic block containing this bundle.

Definition at line 448 of file MachineInstrBuilder.h.

MIBundleBuilder& llvm::MIBundleBuilder::insert	(	MachineBasicBlock::instr_iterator	I,
		MachineInstr *	MI
	)		[inline]

Insert MI into this bundle before I which must point to an instruction in the bundle, or end().

Definition at line 462 of file MachineInstrBuilder.h.

MIBundleBuilder& llvm::MIBundleBuilder::prepend

(

[inline]

Insert MI into MBB by prepending it to the instructions in the bundle. MI will become the first instruction in the bundle.
