/* 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., ANNOTATE_NEW_MEMORY).
Actual implementation of these macros may differ depending on the
dynamic analysis tool being used.
See http://code.google.com/p/data-race-test/ for more information.
This file supports the following dynamic analysis tools:
- None (DYNAMIC_ANNOTATIONS_ENABLED is not defined or zero).
Macros are defined empty.
- ThreadSanitizer, Helgrind, DRD (DYNAMIC_ANNOTATIONS_ENABLED is 1).
Macros are defined as calls to non-inlinable empty functions
that are intercepted by Valgrind. */

/* -------------------------------------------------------------
Annotations useful when implementing condition variables such as CondVar,
using conditional critical sections (Await/LockWhen) and when constructing
user-defined synchronization mechanisms.
The annotations ANNOTATE_HAPPENS_BEFORE() and ANNOTATE_HAPPENS_AFTER() can
be used to define happens-before arcs in user-defined synchronization
mechanisms: the race detector will infer an arc from the former to the
latter when they share the same argument pointer.
Example 1 (reference counting):
void Unref() {
ANNOTATE_HAPPENS_BEFORE(&refcount_);
if (AtomicDecrementByOne(&refcount_) == 0) {
ANNOTATE_HAPPENS_AFTER(&refcount_);
delete this;
}
}
Example 2 (message queue):
void MyQueue::Put(Type *e) {
MutexLock lock(&mu_);
ANNOTATE_HAPPENS_BEFORE(e);
PutElementIntoMyQueue(e);
}
Type *MyQueue::Get() {
MutexLock lock(&mu_);
Type *e = GetElementFromMyQueue();
ANNOTATE_HAPPENS_AFTER(e);
return e;
}
Note: when possible, please use the existing reference counting and message
queue implementations instead of inventing new ones. */
