Register const TargetRegisterInfo * TRI

bool isVarArg() const

isVarArg - Return true if this function takes a variable number of arguments.

The MachineFrameInfo class represents an abstract stack frame until prolog/epilog code is inserted.

LLVM_ABI int CreateFixedObject(uint64_t Size, int64_t SPOffset, bool IsImmutable, bool isAliased=false)

Create a new object at a fixed location on the stack.

LLVM_ABI int CreateStackObject(uint64_t Size, Align Alignment, bool isSpillSlot, const AllocaInst *Alloca=nullptr, uint8_t ID=0)

Create a new statically sized stack object, returning a nonnegative identifier to represent it.

LLVM_ABI uint64_t estimateStackSize(const MachineFunction &MF) const

Estimate and return the size of the stack frame.

const TargetSubtargetInfo & getSubtarget() const

getSubtarget - Return the subtarget for which this machine code is being compiled.

MachineFrameInfo & getFrameInfo()

getFrameInfo - Return the frame info object for the current function.

Function & getFunction()

Return the LLVM function that this machine code represents.

Ty * cloneInfo(const Ty &Old)

TargetRegisterInfo base class - We assume that the target defines a static array of TargetRegisterDes...

virtual const TargetRegisterInfo * getRegisterInfo() const =0

Return the target's register information.

MachineFunctionInfo * clone(BumpPtrAllocator &Allocator, MachineFunction &DestMF, const DenseMap< MachineBasicBlock *, MachineBasicBlock * > &Src2DstMBB) const override

Make a functionally equivalent copy of this MachineFunctionInfo in MF.

XCoreFunctionInfo()=default

This is an optimization pass for GlobalISel generic memory operations.

BumpPtrAllocatorImpl<> BumpPtrAllocator

The standard BumpPtrAllocator which just uses the default template parameters.

This struct is a compact representation of a valid (non-zero power of two) alignment.
