Hello, I'm working on a compiler based on LLVM for a SIMD architecture that supports instruction predication. We would like to implement branching on this architecture using predication. As you know the LLVM-IR doesn't support instruction predication, so I'm not exactly sure on what is the best way to implement it. We came up with some ways to do it in LLVM: - Do not add any
