Instances of this class represent a uniqued identifier for a section in the current translation unit...
Definition: MCSection.h:40
Context object for machine code objects.
Definition: MCContext.h:51
MCSection * SelectSectionForGlobal(const GlobalObject *GO, SectionKind Kind, const TargetMachine &TM) const override
The instances of the Type class are immutable: once they are created, they are never changed...
Definition: Type.h:45
SectionKind - This is a simple POD value that classifies the properties of a section.
Definition: SectionKind.h:23
void Initialize(MCContext &Ctx, const TargetMachine &TM) override
This method must be called before any actual lowering is done.
This represents a section on linux, lots of unix variants and some bare metal systems.
Definition: MCSectionELF.h:30
const unsigned Kind
Primary interface to the complete machine description for the target machine.
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...
bool isGlobalInSmallSection(const GlobalObject *GO, const TargetMachine &TM) const
Return true if this global value should be placed into small data/bss section.
