-// LLNDK (https://source.android.com/docs/core/architecture/vndk/build-system#ll-ndk) is similar to
-// NDK, but uses its own versioning of YYYYMM format for vendor builds. The LLNDK symbols are
-// enabled when the vendor api level is equal to or newer than the ro.board.api_level. These symbols
-// must be annotated in map.txt files with the `# llndk=YYYYMM` annotation. They also must be marked
-// with `__INTRODUCED_IN_LLNDK(YYYYMM)` in the header files. It leaves a no-op annotation for ABI
-// analysis.
