Machine Check Debug Module
TargetMachine & TM
Target machine description.
void emitXRayTable()
Emit a table with all XRay instrumentation points.
MachineFunction * MF
The current machine function.
bool doInitialization(Module &M) override
Set up the AsmPrinter when we are working on a new module.
AsmPrinter(TargetMachine &TM, std::unique_ptr< MCStreamer > Streamer, char &ID=AsmPrinter::ID)
bool runOnMachineFunction(MachineFunction &MF) override
Emit the specified function out to the OutStreamer.
std::unique_ptr< MCStreamer > OutStreamer
This is the MCStreamer object for the file we are generating.
unsigned getPointerSize() const
Return the pointer size from the TargetMachine.
Streaming machine code generation interface.
MCSymbol - Instances of this class represent a symbol name in the MC file, and MCSymbols are created ...
Target specific streamer interface.
Abstract base class for all machine specific constantpool value subclasses.
Representation of each machine instruction.
A Module instance is used to store all the information related to an LLVM module.
StringRef - Represent a constant reference to a string, i.e.
static char ID
Definition SystemZAsmPrinter.h:28
StringRef getPassName() const override
getPassName - Return a nice clean name for a pass.
Definition SystemZAsmPrinter.h:108
bool runOnMachineFunction(MachineFunction &MF) override
Emit the specified function out to the OutStreamer.
Definition SystemZAsmPrinter.h:117
SystemZAsmPrinter(TargetMachine &TM, std::unique_ptr< MCStreamer > Streamer)
Definition SystemZAsmPrinter.h:102
bool doInitialization(Module &M) override
Set up the AsmPrinter when we are working on a new module.
Definition SystemZAsmPrinter.h:126
Primary interface to the complete machine description for the target machine.
This class implements an extremely fast bulk output stream that can only output to a stream.
This is an optimization pass for GlobalISel generic memory operations.
OutputIt move(R &&Range, OutputIt Out)
Provide wrappers to std::move which take ranges instead of having to pass begin/end explicitly.
Implement std::hash so that hash_code can be used in STL containers.
