Definition: ELF_riscv.cpp:479
This is an important base class in LLVM.
Definition: Constant.h:41
A parsed version of the target data layout string in and methods for querying it.
Definition: DataLayout.h:110
Context object for machine code objects.
Definition: MCContext.h:81
Base class for the full range of assembler expressions which are needed for parsing.
Definition: MCExpr.h:35
Instances of this class represent a uniqued identifier for a section in the current translation unit.
Definition: MCSection.h:39
Streaming machine code generation interface.
Definition: MCStreamer.h:212
MCSymbol - Instances of this class represent a symbol name in the MC file, and MCSymbols are created ...
Definition: MCSymbol.h:40
This represents an "assembler immediate".
Definition: MCValue.h:36
This class contains meta information specific to a module.
A Module instance is used to store all the information related to an LLVM module.
Definition: Module.h:65
This implementation is used for RISC-V ELF targets.
bool isGlobalInSmallSection(const GlobalObject *GO, const TargetMachine &TM) const
Return true if this global address should be placed into small data/bss section.
MCSection * SelectSectionForGlobal(const GlobalObject *GO, SectionKind Kind, const TargetMachine &TM) const override
void getModuleMetadata(Module &M) override
Get the module-level metadata that the platform cares about.
MCSection * getSectionForConstant(const DataLayout &DL, SectionKind Kind, const Constant *C, Align &Alignment) const override
Given a constant with the SectionKind, return a section that it should be placed in.
bool isInSmallSection(uint64_t Size) const
void Initialize(MCContext &Ctx, const TargetMachine &TM) override
This method must be called before any actual lowering is done.
unsigned getTextSectionAlignment() const override
bool isConstantInSmallSection(const DataLayout &DL, const Constant *CN) const
Return true if this constant should be placed into small data section.
const MCExpr * getIndirectSymViaGOTPCRel(const GlobalValue *GV, const MCSymbol *Sym, const MCValue &MV, int64_t Offset, MachineModuleInfo *MMI, MCStreamer &Streamer) const override
