Hi everybody, Recently, I found the Lifelong Code Optimization project on the website. And I have a question here, would you please explain it for me? In the home page of the project, it is said that the Goal of the project is to enable mordern programs to be optimized at link time with all static binary code. Here I wonder, why the library code must be static, i.e. why a dynamically

...and intensely optimize those portions of the program. Since we're talking about pretty intense optimization here, we're generally not talking about interpreted or dynamically linked software. The overhead of dynamically linking a library can be very large and it thwarts some of the goals of LLCO. When the *whole* program is represented in LLVM, it is possible to apply optimizations that you couldn't do otherwise. If portions of the program are dynamically loaded then these optimizations are not available. For example, if you have the entire program to ponder, it would allow you to remo...
