This file defines the SmallVector class.
InstListType::const_iterator const_iterator
Representation of each machine instruction.
Wrapper class representing virtual and physical registers.
This is a 'vector' (really, a variable-sized array), optimized for the case when the array is small.
bool createEntriesInEntryBlock(DebugLoc DbgLoc)
Create initial definitions of swifterror values in the entry block of the current function.
void setFunction(MachineFunction &MF)
Initialize data structures for specified new function.
Register getOrCreateVReg(const MachineBasicBlock *, const Value *)
Get or create the swifterror value virtual register in VRegDefMap for this basic block.
void setCurrentVReg(const MachineBasicBlock *MBB, const Value *, Register)
Set the swifterror virtual register in the VRegDefMap for this basic block.
Register getOrCreateVRegUseAt(const Instruction *, const MachineBasicBlock *, const Value *)
Get or create the swifterror value virtual register for a use of a swifterror by an instruction.
void preassignVRegs(MachineBasicBlock *MBB, BasicBlock::const_iterator Begin, BasicBlock::const_iterator End)
Register getOrCreateVRegDefAt(const Instruction *, const MachineBasicBlock *, const Value *)
Get or create the swifterror value virtual register for a def of a swifterror by an instruction.
const Value * getFunctionArg() const
Get the (unique) function argument that was marked swifterror, or nullptr if this function has no swi...
