-/* This file defines dynamic annotations for use with dynamic analysis
- * tool such as ThreadSanitizer, Valgrind, 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.
- *
- * By using dynamic annotations a developer can give more details to the dynamic
- * analysis tool to improve its precision.
- *
- * In C/C++ program the annotations are represented as C macros.
- * With the default build flags, these macros are empty, hence don't affect
- * performance of a compiled binary.
- * If dynamic annotations are enabled, they just call no-op functions.
- * The dynamic analysis tools can intercept these functions and replace them
- * with their own implementations.
- *
- * See http://code.google.com/p/data-race-test/wiki/DynamicAnnotations for more
- * information.
