// just FunctionPass's, except they operate on machine code as part of a code

|
// generator. Because they operate on machine code, not the LLVM

|
// representation, MachineFunctionPass's are not allowed to modify the LLVM

|
// representation. Due to this limitation, the MachineFunctionPass class takes
|
|
// care of declaring that no LLVM passes are invalidated.
