FunctionPass class - This class is used to implement most global optimizations.

MachineFunctionPass - This class adapts the FunctionPass interface to allow convenient creation of pa...

Properties which a MachineFunction may have at a given point in time.

StringRef - Represent a constant reference to a string, i.e.

TargetInstrInfo - Interface to description of machine instruction set.

unsigned ID

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

This is an optimization pass for GlobalISel generic memory operations.
