LLVM 5.0
LLVMSwift now builds against LLVM 5.0. We are no longer testing 4.0 backwards deployment, but we anticipate that the framework will continue to build against 4.0 for quite a while.
LLVMSwift now requires Xcode 9’s toolchain.
Previously deprecated short names of integer predicates have been removed in favor of their Swiftier longer names.
