Evaluate is a versatile tool, or say a Swiss army knife, to help you revise the default behavior of softwares. For example, you can enable PGO (profile-guide optimization) or LTO (link-time optimization) on a very easy way. With Evaluate, you don’t need to handle with all details of Makefiles and building system any more. All that you need to do is to set -flto and -fprofile-generate/use as a default mark of gcc by using evaluate.
