If exception handling is supported by the target, this is the section the Language Specific Data Area...

MCContext & getContext() const

Wrapper class representing physical registers. Should be passed by value.

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

Streaming machine code generation interface.

bool hasFeature(unsigned Feature) const

static const MCSymbolRefExpr * create(const MCSymbol *Symbol, MCContext &Ctx)

MCSymbol - Instances of this class represent a symbol name in the MC file, and MCSymbols are created ...

This represents an "assembler immediate".

int64_t getConstant() const

This class contains meta information specific to a module.

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