we weren't actually using these sources anymore, okay?

-// This file defines dynamic annotations for use with dynamic analysis tool
-// such as valgrind, PIN, etc.
-//
-// Dynamic annotation is a source code annotation that affects the generated
-// code (that is, the annotation is not a comment). Each such annotation is
-// attached to a particular instruction and/or to a particular object (address)
-// in the program.
-//
-// The annotations that should be used by users are macros in all upper-case
-// (e.g., ABSL_ANNOTATE_THREAD_NAME).
-//
-// Actual implementation of these macros may differ depending on the dynamic
-// analysis tool being used.
-//
-// This file supports the following configurations:
-// - Dynamic Annotations enabled (with static thread-safety warnings disabled).
-//   In this case, macros expand to functions implemented by Thread Sanitizer,
-//   when building with TSan. When not provided an external implementation,
-//   dynamic_annotations.cc provides no-op implementations.
-//
-// - Static Clang thread-safety warnings enabled.
-//   When building with a Clang compiler that supports thread-safety warnings,
-//   a subset of annotations can be statically-checked at compile-time. We
-//   expand these macros to static-inline functions that can be analyzed for
-//   thread-safety, but afterwards elided when building the final binary.
-//
-// - All annotations are disabled.
-//   If neither Dynamic Annotations nor Clang thread-safety warnings are
-//   enabled, then all annotation-macros expand to empty.
