AArch64TargetStreamer(MCStreamer &S)
void emitConstantPools() override
const MCExpr * addConstantPoolEntry(const MCExpr *, unsigned Size, SMLoc Loc)
Callback used to implement the ldr= pseudo.
~AArch64TargetStreamer() override
void emitNoteSection(unsigned Flags, uint64_t PAuthABIPlatform=-1, uint64_t PAuthABIVersion=-1)
Callback used to implement the .note.gnu.property section.
void emitCurrentConstantPool()
Callback used to implement the .ltorg directive.
virtual void emitInst(uint32_t Inst)
Callback used to implement the .inst directive.
Context object for machine code objects.
MCSectionELF * getELFSection(const Twine &Section, unsigned Type, unsigned Flags)
void reportWarning(SMLoc L, const Twine &Msg)
Base class for the full range of assembler expressions which are needed for parsing.
This represents a section on linux, lots of unix variants and some bare metal systems.
Instances of this class represent a uniqued identifier for a section in the current translation unit.
bool isRegistered() const
Streaming machine code generation interface.
MCContext & getContext() const
virtual void emitValueToAlignment(Align Alignment, int64_t Value=0, unsigned ValueSize=1, unsigned MaxBytesToEmit=0)
Emit some number of copies of Value until the byte alignment ByteAlignment is reached.
virtual void emitIntValue(uint64_t Value, unsigned Size)
Special case of EmitValue that avoids the client having to pass in a MCExpr for constant integers.
MCSymbol * endSection(MCSection *Section)
virtual void switchSection(MCSection *Section, uint32_t Subsec=0)
Set the current section where code is being emitted to Section.
MCSection * getCurrentSectionOnly() const
virtual void emitBytes(StringRef Data)
Emit the bytes in Data into the output.
Generic base class for all target subtargets.
const Triple & getTargetTriple() const
Target specific streamer interface.
MCStreamer & getStreamer()
Represents a location in source code.
StringRef - Represent a constant reference to a string, i.e.
Triple - Helper class for working with autoconf configuration names.
@ C
The default llvm calling convention, compatible with C.

This is an optimization pass for GlobalISel generic memory operations.
MCTargetStreamer * createAArch64NullTargetStreamer(MCStreamer &S)
MCTargetStreamer * createAArch64ObjectTargetStreamer(MCStreamer &S, const MCSubtargetInfo &STI)
This struct is a compact representation of a valid (non-zero power of two) alignment.
