This is an important base class in LLVM.
Definition: Constant.h:41
A parsed version of the target data layout string in and methods for querying it.
Definition: DataLayout.h:114
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.
void Initialize(MCContext &Ctx, const TargetMachine &TM) override
This method must be called before any actual lowering is done.
MCSection * SelectSectionForGlobal(const GlobalObject *GO, SectionKind Kind, const TargetMachine &TM) const override
bool isConstantInSmallSection(const DataLayout &DL, const Constant *CN) const
Return true if this constant should be placed into small data section.
Context object for machine code objects.
Definition: MCContext.h:76
Instances of this class represent a uniqued identifier for a section in the current translation unit.
Definition: MCSection.h:39
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.

@ C
The default llvm calling convention, compatible with C.
Definition: CallingConv.h:34
This is an optimization pass for GlobalISel generic memory operations.
Definition: AddressRanges.h:18
This struct is a compact representation of a valid (non-zero power of two) alignment.
