| # GCC Compatibility of Builtins |
| |
| LLVM-libc is written with Clang as the reference compiler but is expected to |
| build under GCC as well. Many headers reach for compiler intrinsics |
| (`__builtin_*`) for fast paths and for IEEE-754 semantics. Not every |
| `__builtin_*` exists in every compiler. a large family is Clang-only, |
| and several others were added in specific GCC releases. This page records |
| which builtins the libc code base references today and the minimum GCC |
| basepoint that ships each one. |
