For example, if the compiler discovers that a function is called many different times with the same initial parameter, it may clone the function to produce a version which takes one less parameter, and then change all the callers to call the clone. Another example is that a compiler may make several clones of a function and compile them tuned for different microarchitectures, and then arrange for the appropriate one to be used at runtime based on some sort of CPU test.
