const TargetSubtargetInfo & getSubtarget() const

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

void ensureAlignment(Align A)

ensureAlignment - Make sure the function is at least A bytes aligned.

unsigned ID

LLVM IR allows to use arbitrary numbers as calling convention identifiers.

This is an optimization pass for GlobalISel generic memory operations.

MachineInstrBuilder BuildMI(MachineFunction &MF, const MIMetadata &MIMD, const MCInstrDesc &MCID)

Builder interface. Specify how to create the initial instruction itself.

char & PatchableFunctionID

This pass implements the "patchable-function" attribute.

void initializePatchableFunctionPass(PassRegistry &)

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