Any open source projects which are available to work on

I’m a gsoc contributor for GNU, and my goal is to get into open source projects for LLVM, and other compiler toolchains , I wanted to start off with rustc and clang as I was a bit familiar with those, and worked on them throughout my gsoc project, but wanted to shift towards LLVM. Currently I was wondering if there are any open projects I could start working on similar to any of the ones offered as gsoc ideas this year?
