This is an important base class in LLVM.

A parsed version of the target data layout string in and methods for querying it.

StringRef getSection() const

Get the custom section of this global if it has one.

bool hasLocalLinkage() const

const DataLayout & getDataLayout() const

Get the data layout of the module this global belongs to.

Type * getValueType() const

Context object for machine code objects.

MCSectionELF * getELFSection(const Twine &Section, unsigned Type, unsigned Flags)

MCSection * MergeableConst16Section

MCSection * MergeableConst4Section

MCSection * TextSection

Section directive for standard text.

MCSection * MergeableConst8Section

MCSection * DataRelROSection

MCSection * CStringSection

MCSection * ReadOnlySection

Section that is readonly and can contain arbitrary initialized data.

MCSection * BSSSection

Section that is default initialized to zero.

MCContext & getContext() const

MCSection * DataSection

Section directive for standard data.

Instances of this class represent a uniqued identifier for a section in the current translation unit.

SectionKind - This is a simple POD value that classifies the properties of a section.

StringRef - Represent a constant reference to a string, i.e.

void Initialize(MCContext &Ctx, const TargetMachine &TM) override

This method must be called before any actual lowering is done.

Primary interface to the complete machine description for the target machine.

CodeModel::Model getCodeModel() const

Returns the code model.

The instances of the Type class are immutable: once they are created, they are never changed.

bool isSized(SmallPtrSetImpl< Type * > *Visited=nullptr) const

Return true if it makes sense to take the size of this type.

void Initialize(MCContext &Ctx, const TargetMachine &TM) override

This method must be called before any actual lowering is done.

MCSection * getExplicitSectionGlobal(const GlobalObject *GO, SectionKind Kind, const TargetMachine &TM) const override

Targets should implement this method to assign a section to globals with an explicit section specfied...

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.

MCSection * SelectSectionForGlobal(const GlobalObject *GO, SectionKind Kind, const TargetMachine &TM) const override

@ C

The default llvm calling convention, compatible with C.

All sections with the "d" flag are grouped together by the linker to form the data section and the dp...

This is an optimization pass for GlobalISel generic memory operations.

void report_fatal_error(Error Err, bool gen_crash_diag=true)

Report a serious error, calling any installed error handler.

This struct is a compact representation of a valid (non-zero power of two) alignment.
