/* 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.
