+/* The purpose of this file is to export a small set of atomic-related
+ * functions from the C library, to ensure binary ABI compatibility for
+ * the NDK.
+ *
+ * These functions were initially exposed by the NDK through <sys/atomics.h>,
+ * which was unfortunate because their implementation didn't provide any
+ * memory barriers at all.
+ *
+ * This wasn't a problem for the platform code that used them, because it
+ * used explicit barrier instructions around them. On the other hand, it means
+ * that any NDK-generated machine code that linked against them would not
+ * perform correctly when running on multi-core devices.
+ *
+ * To fix this, the platform code was first modified to not use any of these
+ * functions (everything is now inlined through assembly statements, see
+ * libc/private/bionic_arm_inline.h and the headers it includes.
+ *
+ * The functions here are thus only for the benefit of NDK applications,
+ * and now includes full memory barriers to prevent any random memory ordering
+ * issue from cropping.
+ *
+ * Note that we also provide an updated <sys/atomics.h> header that defines
+ * always_inlined versions of the functions that use the GCC builtin
+ * intrinsics to perform the same thing.
+ *
+ * NOTE: There is no need for a similar file for non-ARM platforms.

+ * ===========================================================================
+ *      Deadlock prediction
+ * ===========================================================================
+ */
+/*
+The idea is to predict the possibility of deadlock by recording the order
+in which locks are acquired.  If we see an attempt to acquire a lock
+out of order, we can identify the locks and offending code.
+
+To make this work, we need to keep track of the locks held by each thread,
+and create history trees for each lock.  When a thread tries to acquire
+a new lock, we walk through the "history children" of the lock, looking
+for a match with locks the thread already holds.  If we find a match,
+it means the thread has made a request that could result in a deadlock.
+
+To support recursive locks, we always allow re-locking a currently-held
+lock, and maintain a recursion depth count.
+
+An ASCII-art example, where letters represent locks:
+
+        A
+       /|\
+      / | \
+     B  |  D
+      \ |
+       \|
+        C
+
+The above is the tree we'd have after handling lock synchronization
+sequences "ABC", "AC", "AD".  A has three children, {B, C, D}.  C is also
+a child of B.  (The lines represent pointers between parent and child.
+Every node can have multiple parents and multiple children.)
+
+If we hold AC, and want to lock B, we recursively search through B's
+children to see if A or C appears.  It does, so we reject the attempt.
+(A straightforward way to implement it: add a link from C to B, then
+determine whether the graph starting at B contains a cycle.)
+
+If we hold AC and want to lock D, we would succeed, creating a new link
+from C to D.
+
+Updates to MutexInfo structs are only allowed for the thread that holds
+the lock, so we actually do most of our deadlock prediction work after
+the lock has been acquired.
