R600FrameLowering(StackDirection D, Align StackAl, int LAO, Align TransAl=Align::None())
int getFrameIndexReference(const MachineFunction &MF, int FI, unsigned &FrameReg) const override
Interface to describe a layout of a stack frame on an AMDGPU target.
~R600FrameLowering() override
void emitEpilogue(MachineFunction &MF, MachineBasicBlock &MBB) const override
static constexpr const Align None()
Returns a default constructed Align which corresponds to no alignment.
Definition: Alignment.h:93
This struct is a compact representation of a valid (non-zero power of two) alignment.
Definition: Alignment.h:40
bool hasFP(const MachineFunction &MF) const override
hasFP - Return true if the specified function should have a dedicated frame pointer register...
static GCRegistry::Add< StatepointGC > D("statepoint-example", "an example strategy for statepoint")
void emitPrologue(MachineFunction &MF, MachineBasicBlock &MBB) const override
emitProlog/emitEpilog - These methods insert prolog and epilog code into the function.
Information about the stack frame layout on the AMDGPU targets.
