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:47

Parameters

llvm::MCContext& Ctx

const llvm::TargetMachine& TM

¶void InitializeELF(bool UseInitArray_)

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

Parameters

bool UseInitArray_

    const llvm::GlobalObject* GO,
    llvm::SectionKind Kind,
    const llvm::TargetMachine& TM) const

Parameters

llvm::MCStreamer& Streamer

const llvm::DataLayout& DL

const llvm::MCSymbol* Sym

¶llvm::MCSymbol* getCFIPersonalitySymbol(
    const llvm::GlobalValue* GV,

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:63

Parameters

const llvm::GlobalObject* GO

Parameters

llvm::Module& M

¶llvm::MCSection* getSectionForCommandLines() const

Description

If supported, return the section to use for the llvm.commandline metadata. Otherwise, return nullptr.

Declared at: llvm/include/llvm/CodeGen/TargetLoweringObjectFileImpl.h:112

¶llvm::MCSection* getSectionForConstant(

    llvm::SectionKind Kind,
    const llvm::Constant* C,
    llvm::Align& Alignment) const

Description

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