BPFAsmPrinter(TargetMachine &TM, std::unique_ptr< MCStreamer > Streamer)
bool doFinalization(Module &M) override
Shut down the asmprinter.
bool PrintAsmOperand(const MachineInstr *MI, unsigned OpNo, const char *ExtraCode, raw_ostream &O) override
Print the specified operand of MI, an INLINEASM instruction, using the specified assembler variant.
bool doInitialization(Module &M) override
Set up the AsmPrinter when we are working on a new module.
virtual void emitJumpTableInfo() override
Print assembly representations of the jump tables used by the current function to the current output ...
void emitInstruction(const MachineInstr *MI) override
Targets should implement this to emit instructions.
Collect and emit BTF information.

MCSymbol - Instances of this class represent a symbol name in the MC file, and MCSymbols are created ...
Definition MCSymbol.h:42
Representation of each machine instruction.
A Module instance is used to store all the information related to an LLVM module.
Definition Module.h:67
StringRef - Represent a constant reference to a string, i.e.
Definition StringRef.h:55
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.
Definition raw_ostream.h:53
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.
Definition STLExtras.h:1847
Implement std::hash so that hash_code can be used in STL containers.
