bool isBlockOnlyReachableByFallthrough(const MachineBasicBlock *MBB) const override
Return true if the basic block has exactly one predecessor and the control transfer mechanism between...
bool PrintAsmOperand(const MachineInstr *MI, unsigned OpNo, const char *ExtraCode, raw_ostream &OS) override
PrintAsmOperand - Print out an operand for an inline asm expression.
StringRef getPassName() const override
getPassName - Return a nice clean name for a pass.
void emitInstruction(const MachineInstr *MI) override
Print out a single Hexagon MI to the current output stream.
void LowerPATCHABLE_TAIL_CALL(const MachineInstr &MI)
HexagonAsmPrinter(TargetMachine &TM, std::unique_ptr< MCStreamer > Streamer)

void HexagonProcessInstruction(MCInst &Inst, const MachineInstr &MBB)
Instances of this class represent a single low-level machine instruction.
Definition: MCInst.h:184
const TargetSubtargetInfo & getSubtarget() const
getSubtarget - Return the subtarget for which this machine code is being compiled.
Representation of each machine instruction.
Definition: MachineInstr.h:69
StringRef - Represent a constant reference to a string, i.e.
Definition: StringRef.h:50
Primary interface to the complete machine description for the target machine.
Definition: TargetMachine.h:76
This class implements an extremely fast bulk output stream that can only output to a stream.
Definition: raw_ostream.h:52
This is an optimization pass for GlobalISel generic memory operations.
Definition: AddressRanges.h:18
OutputIt move(R &&Range, OutputIt Out)
Provide wrappers to std::move which take ranges instead of having to pass begin/end explicitly.
Definition: STLExtras.h:1858
Implement std::hash so that hash_code can be used in STL containers.
