Hi all, I am a student from Bangalore, India. I'd like to participate in GSoC 2022. The idea about incremental LTO caught my eye.
> At the moment, LTO re-optimizes and generates code for the whole program or library if just one object file changes, even an insignificant way. The contributor working on this project will write code determining what changes in LTO input are significant for various stages of LTO processing and try not to redo the work which is would lead to the same results as before. Is there a sample project I can try to get familiar with the code? I suppose this will involve optimizing WHOPR phases. Is there any literature I should get myself familiar with?
