URL: https://github.com/llvm/llvm-project/commit/62a251f824f63a56563b246035b9bd24078aa98b DIFF: https://github.com/llvm/llvm-project/commit/62a251f824f63a56563b246035b9bd24078aa98b.diff LOG: [Clang][BFloat16] Upgrade __bf16 by supporting increment/decrement operations Since __bf16 has been upgraded from a storage-only type to an arithmetic type in https://reviews.llvm.org/rGe62175736551abf40a3410bc246f58e650eb8158, it should support all the basic arithmetic operations like other float types, including increment and decrement.
