+# The sanitizer ignorelists are default special-case lists that the Clang
+# driver passes to the compiler (via -fsanitize-system-ignorelist) when the
+# corresponding sanitizer is enabled. They are consumed by the compiler rather
+# than linked into any runtime library, so they are built by their own target
+# that does not depend on the sanitizer runtimes and can be built on its own.
