Public Member Functions | |
MIBundleBuilder (MachineBasicBlock &BB, MachineBasicBlock::iterator Pos) | |
Create an MIBundleBuilder that inserts instructions into a new bundle in BB above the bundle or instruction at Pos. | |
MIBundleBuilder (MachineBasicBlock &BB, MachineBasicBlock::iterator B, MachineBasicBlock::iterator E) | |
Create a bundle from the sequence of instructions between B and E. | |
MIBundleBuilder (MachineInstr *MI) | |
Create an MIBundleBuilder representing an existing instruction or bundle that has MI as its head. | |
MachineBasicBlock & | getMBB () const |
Return a reference to the basic block containing this bundle. | |
bool | empty () const |
Return true if no instructions have been inserted in this bundle yet. | |
MachineBasicBlock::instr_iterator | begin () const |
Return an iterator to the first bundled instruction. | |
MachineBasicBlock::instr_iterator | end () const |
Return an iterator beyond the last bundled instruction. | |
MIBundleBuilder & | insert (MachineBasicBlock::instr_iterator I, MachineInstr *MI) |
Insert MI into this bundle before I which must point to an instruction in the bundle, or end(). | |
MIBundleBuilder & | prepend (MachineInstr *MI) |
Insert MI into MBB by prepending it to the instructions in the bundle. | |
MIBundleBuilder & | append (MachineInstr *MI) |
Insert MI into MBB by appending it to the instructions in the bundle. | |
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.
