Methods

¶void Initialize(llvm::MCContext& Ctx,
                const llvm::TargetMachine& TM)

Description

This method must be called before any actual lowering is done. This specifies the current context for codegen, and gives the lowering implementations a chance to set up their default sections.

Declared at: llvm/include/llvm/CodeGen/TargetLoweringObjectFileImpl.h:102

Parameters

llvm::MCContext& Ctx

const llvm::TargetMachine& TM

¶llvm::MCSection* SelectSectionForGlobal(
    const llvm::GlobalObject* GO,
    llvm::SectionKind Kind,
    const llvm::TargetMachine& TM) const

Declared at: llvm/include/llvm/CodeGen/TargetLoweringObjectFileImpl.h:107

Parameters

const llvm::GlobalObject* GO

llvm::SectionKind Kind

const llvm::TargetMachine& TM

¶TargetLoweringObjectFileMachO()

Declared at: llvm/include/llvm/CodeGen/TargetLoweringObjectFileImpl.h:99

¶void emitModuleMetadata(
    llvm::MCStreamer& Streamer,
    llvm::Module& M) const

Description

Emit the module flags that specify the garbage collection information.

Declared at: llvm/include/llvm/CodeGen/TargetLoweringObjectFileImpl.h:105

Parameters

llvm::MCStreamer& Streamer

llvm::Module& M

¶llvm::MCSymbol* getCFIPersonalitySymbol(
    const llvm::GlobalValue* GV,
    const llvm::TargetMachine& TM,
    llvm::MachineModuleInfo* MMI) const

Declared at: llvm/include/llvm/CodeGen/TargetLoweringObjectFileImpl.h:125

Parameters

const llvm::GlobalValue* GV

const llvm::TargetMachine& TM

llvm::MachineModuleInfo* MMI

¶llvm::MCSection* getExplicitSectionGlobal(
    const llvm::GlobalObject* GO,
    llvm::SectionKind Kind,
    const llvm::TargetMachine& TM) const

Description

Targets should implement this method to assign a section to globals with an explicit section specfied. The implementation of this method can assume that GO->hasSection() is true.

Declared at: llvm/include/llvm/CodeGen/TargetLoweringObjectFileImpl.h:110

Parameters

const llvm::GlobalObject* GO

llvm::SectionKind Kind

const llvm::TargetMachine& TM

¶const llvm::MCExpr* getIndirectSymViaGOTPCRel(
    const llvm::GlobalValue* GV,
    const llvm::MCSymbol* Sym,
    const llvm::MCValue& MV,
    int64_t Offset,
    llvm::MachineModuleInfo* MMI,
    llvm::MCStreamer& Streamer) const

Description

Get MachO PC relative GOT entry relocation

Declared at: llvm/include/llvm/CodeGen/TargetLoweringObjectFileImpl.h:130

Parameters

const llvm::GlobalValue* GV

const llvm::MCSymbol* Sym

const llvm::MCValue& MV

int64_t Offset

llvm::MachineModuleInfo* MMI

llvm::MCStreamer& Streamer

¶void getNameWithPrefix(
    SmallVectorImpl<char>& OutName,
    const llvm::GlobalValue* GV,
    const llvm::TargetMachine& TM) const

Declared at: llvm/include/llvm/CodeGen/TargetLoweringObjectFileImpl.h:136

Parameters

¶llvm::MCSection* getSectionForConstant(
    const llvm::DataLayout& DL,
    llvm::SectionKind Kind,
    const llvm::Constant* C,
    unsigned int& Align) const

Description

Given a constant with the SectionKind, return a section that it should be placed in.

Declared at: llvm/include/llvm/CodeGen/TargetLoweringObjectFileImpl.h:113

Parameters

const llvm::DataLayout& DL

llvm::SectionKind Kind

const llvm::Constant* C

    const llvm::GlobalValue* GV,
    unsigned int Encoding,
    const llvm::TargetMachine& TM,
