void Initialize(MCContext &Ctx, const TargetMachine &TM) override
This method must be called before any actual lowering is done.
bool isGlobalInSmallSection(const GlobalObject *GO, const TargetMachine &TM) const
Return true if this global value should be placed into small data/bss section.

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...
const Function * getLutUsedFunction(const GlobalObject *GO) const
Context object for machine code objects.

This represents a section on linux, lots of unix variants and some bare metal systems.
Definition: MCSectionELF.h:27
Instances of this class represent a uniqued identifier for a section in the current translation unit.
Definition: MCSection.h:36
SectionKind - This is a simple POD value that classifies the properties of a section.
Definition: SectionKind.h:22
Primary interface to the complete machine description for the target machine.

The instances of the Type class are immutable: once they are created, they are never changed.
Definition: Type.h:45
This is an optimization pass for GlobalISel generic memory operations.
