I find that when two i16 numbers or i8 numbers are added, it will be extended to i32. Even if I choose to compile it with '-fsanitize=undefined'. So, How can generate the intrinsic 'call @llvm.sadd.with.overflow.i16' ? Additional, how can I find the implementation of llvm.sadd.with.overflow.* in LLVM source code? It's a bit challenging for newbies. Thanks!
