MCSection * SelectSectionForGlobal(const GlobalObject *GO, SectionKind Kind, const TargetMachine &TM) const override
This is an important base class in LLVM.
Definition: Constant.h:41
bool isConstantInSmallSection(const DataLayout &DL, const Constant *CN) const
Return true if this constant should be placed into small data section.
SectionKind - This is a simple POD value that classifies the properties of a section.
Definition: SectionKind.h:22
This struct is a compact representation of a valid (non-zero power of two) alignment.
Definition: Alignment.h:40
MCSection * getSectionForConstant(const DataLayout &DL, SectionKind Kind, const Constant *C, unsigned &Align) const override
Given a constant with the SectionKind, return a section that it should be placed in.
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.
