+/* This header defines three types of macros:
+
+   - atomic arithmetic and logic operation on memory.  They all
+     have the prefix "atomic_".
+
+   - conditionally atomic operations of the same kinds.  These
+     always behave identical but can be faster when atomicity
+     is not really needed since only one thread has access to
+     the memory location.  In that case the code is slower in
+     the multi-thread case.  The interfaces have the prefix
+     "catomic_".
+
+   - support functions like barriers.  They also have the preifx
+     "atomic_".
+
+   Architectures must provide a few lowlevel macros (the compare
+   and exchange definitions).  All others are optional.  They
+   should only be provided if the architecture has specific
+   support for the operation.
+
+   As <atomic.h> macros are usually heavily nested and often use local
+   variables to make sure side-effects are evaluated properly, use for
+   macro local variables a per-macro unique prefix.  This file uses
+   __atgN_ prefix where N is different in each macro.  */
