- New representation of refs in R9, see erl_term.h
-
- In the first data word, only the usual 18 bits are used. Ordinarily,
- in "long refs" all words are used (in other words, practically never
- wrap around), but for compatibility with older nodes, "short refs"
- exist. Short refs come into being by being converted from the old
- external format for refs (tag REFERENCE_EXT). Short refs are
- converted back to the old external format.
-
- When converting a long ref to the external format in the case of
- preparing for sending to an older node, the ref is truncated by only
- using the first word (with 18 significant bits), and using the old tag
- REFERENCE_EXT.
-
- When comparing refs or different size, only the parts up to the length
- of the shorter operand are used. This has the desirable effect that a
- long ref sent to an old node and back will be treated as equal to
- the original, although some of the bits have been lost.
-
- The hash value for a ref always considers only the first word, since
- in the above scenario, the original and the copy should have the same
- hash value.

+/*
+ * Description: A Red-Black (binary search) Tree implementation. The search,
+ * insert, and delete operations are all O(log n) operations
+ * on a Red-Black Tree. Red-Black Trees are described in
+ * "Introduction to Algorithms", by Thomas H. Cormen, Charles
+ * E. Leiserson, and Ronald L. Riverest.
+ *
+ * Use by defining mandatory defines as well as defines for
+ * API functions wanted, and include this header.
+ *
+ * Author: Rickard Green
+ *
+ *
+ * Mandatory defines:
+ * - ERTS_RBT_PREFIX - Prefix to use on functions.
+ * - ERTS_RBT_T - Type of a tree node.
+ * - ERTS_RBT_KEY_T - Type of key for a tree node.
+ * - ERTS_RBT_FLAGS_T - Type of flags for a tree node.
+ * - ERTS_RBT_INIT_EMPTY_TNODE(T) -Initialize an empty tree node.
+ * - ERTS_RBT_IS_RED(T) - Is tree node red?
+ * - ERTS_RBT_SET_RED(T) - Set tree node red.
+ * - ERTS_RBT_IS_BLACK(T) - Is tree node back?
+ * - ERTS_RBT_SET_BLACK(T) - Set tree node black.
+ * - ERTS_RBT_GET_FLAGS(T) - Get flags of tree node (incl colors).
+ * - ERTS_RBT_SET_FLAGS(T, F) - Set flags of tree note.
+ * - ERTS_RBT_GET_PARENT(T) - Get parent node.
+ * - ERTS_RBT_SET_PARENT(T, P) - Set parent node.
+ * - ERTS_RBT_GET_RIGHT(T) - Get right child node.
+ * - ERTS_RBT_SET_RIGHT(T, R) - Set right child node.
+ * - ERTS_RBT_GET_LEFT(T) - Get left child node.
+ * - ERTS_RBT_SET_LEFT(T, L) - Set left child node.
+ * - ERTS_RBT_GET_KEY(T) - Get key of node.
+ * - ERTS_RBT_IS_LT(KX, KY) - Is key KX less than key KY?
+ * - ERTS_RBT_IS_EQ(KX, KY) - Is key KX equal to key KY?
+ *
+ * Optional defines:
+ *
+ * - ERTS_RBT_UNDEF - Undefine all user defined ERTS_RBT_*
+ * defines after use.
+ *
+ * - ERTS_RBT_NO_API_INLINE - Do not inline API functions.
+ *
+ * Attached data management:
+ * - ERTS_RBT_UPDATE_ATTACHED_DATA_ROTATE(L, OP, NP) - Called
+ * when a rotate operation has been performed. If L (in int)
+ * is a non zero, a left rotation was performed; otherwise,
+ * a right rotation was performed. OR points to the old
+ * parent node and NP points to the new parent node.
+ * - ERTS_RBT_UPDATE_ATTACHED_DATA_DMOD(F, T) - Called when
+ * a delete operation modifies a tree node. A delete
+ * modification is either a removal or replacement of a
+ * node. F points to the parent of the tree node that was
+ * modified. T points to the next ancestor that will be
+ * modified. If T is NULL, no more removal and/or
+ * replacements will be made. One typically wants to update
+ * the attached data of each node between F and T. If T is
+ * NULL all the way up to the root.
+ * - ERTS_RBT_UPDATE_ATTACHED_DATA_CHGROOT(OR, NR) - Called
+ * when the root node changes. OR points to the old
+ * root node and NP points to the new root node.
+ *
+ * Request implementation of API functions:
+ * - ERTS_RBT_WANT_DELETE
+ * - ERTS_RBT_WANT_INSERT
+ * - ERTS_RBT_WANT_LOOKUP_INSERT
+ * - ERTS_RBT_WANT_REPLACE
+ * - ERTS_RBT_WANT_LOOKUP
+ * - ERTS_RBT_WANT_SMALLEST
+ * - ERTS_RBT_WANT_LARGEST
+ * - ERTS_RBT_WANT_FOREACH
+ * - ERTS_RBT_WANT_FOREACH_DESTROY
+ * - ERTS_RBT_WANT_FOREACH_YIELDING
+ * - ERTS_RBT_WANT_FOREACH_DESTROY_YIELDING
+ * - ERTS_RBT_WANT_FOREACH_SMALL
+ * - ERTS_RBT_WANT_FOREACH_LARGE
+ * - ERTS_RBT_WANT_FOREACH_SMALL_DESTROY
+ * - ERTS_RBT_WANT_FOREACH_LARGE_DESTROY
+ * - ERTS_RBT_WANT_FOREACH_SMALL_YIELDING
+ * - ERTS_RBT_WANT_FOREACH_LARGE_YIELDING
+ * - ERTS_RBT_WANT_FOREACH_SMALL_DESTROY_YIELDING
+ * - ERTS_RBT_WANT_FOREACH_LARGE_DESTROY_YIELDING
+ * - ERTS_RBT_WANT_DEBUG_PRINT
+ *
+ * The yield state data type will equal
+ * <ERTS_RBT_PREFIX>_rbt_yield_state_t.
+ *
+ * The yield state should be statically initialized by
+ * ERTS_RBT_YIELD_STAT_INITER.
+ *
+ *
+ * The following API functions are implemented if corresponding
+ * ERTS_RBT_WANT_<OPERATION> is defined:
+ *
+ * - void <ERTS_RBT_PREFIX>_rbt_delete(
+ * ERTS_RBT_T **tree,
+ * ERTS_RBT_T *element);

+ *
+ * - void <ERTS_RBT_PREFIX>_rbt_insert(
+ * ERTS_RBT_T **tree,
+ * ERTS_RBT_T *element);
+ * Insert element into tree.
+ *
+ * - ERTS_RBT_T * <ERTS_RBT_PREFIX>_rbt_lookup_insert(
+ * ERTS_RBT_T **tree,
+ * ERTS_RBT_T *element);
+ * Look up an element in the tree that compares as equal to the
+ * element passed as argument, and return the looked up element.
+ * If no element compared as equal, insert the element passed as
+ * argument into the tree, and return NULL.
+ *
+ * - void <ERTS_RBT_PREFIX>_rbt_replace(
+ * ERTS_RBT_T **tree,
+ * ERTS_RBT_T *old_element,
+ * ERTS_RBT_T *new_element);
+ * Replace old_element in the tree with new_element. Both elements
+ * *should* compare as equal.
+ *
+ * - ERTS_RBT_T * <ERTS_RBT_PREFIX>_rbt_lookup(
+ * ERTS_RBT_T *tree,
+ * ERTS_RBT_KEY_T key);
+ * Look up an element with a key that compares as equal to

+ *
+ * - ERTS_RBT_T * <ERTS_RBT_PREFIX>_rbt_smallest(
+ * ERTS_RBT_T *tree);

/*
-** Support routines for the timer wheel
-**
-** This code contains two strategies for dealing with
-** date/time changes in the system.
-** If the system has some kind of high resolution timer (HAVE_GETHRTIME),
-** the high resolution timer is used to correct the time-of-day and the
-** timeouts, the base source is the hrtimer, but at certain intervals the
-** OS time-of-day is checked and if it is not within certain bounds, the
-** delivered time gets slowly adjusted for each call until
-** it corresponds to the system time (built-in adjtime...).
-** The call gethrtime() is detected by autoconf on Unix, but other
-** platforms may define it in erl_*_sys.h and implement
-** their own high resolution timer. The high resolution timer
-** strategy is (probably) best on all systems where the timer have
-** a resolution higher or equal to gettimeofday (or what's implemented
-** is sys_gettimeofday()). The actual resolution is the interesting thing,
-** not the unit's thats used (i.e. on VxWorks, nanoseconds can be
-** retrieved in terms of units, but the actual resolution is the same as
-** for the clock ticks).
-** If the systems best timer routine is kernel ticks returned from
-** sys_times(), and the actual resolution of sys_gettimeofday() is
-** better (like most unixes that does not have any realtime extensions),
-** another strategy is used. The tolerant gettimeofday() corrects
-** the value with respect to uptime (sys_times() return value) and checks
-** for correction both when delivering timeticks and delivering nowtime.
-** this strategy is slower, but accurate on systems without better timer
-** routines. The kernel tick resolution is not enough to implement
-** a gethrtime routine. On Linux and other non solaris unix-boxes the second
-** strategy is used, on all other platforms we use the first.
-**
-** The following is expected (from sys.[ch] and erl_*_sys.h):
-**
-** 64 bit integers. So it is, and so it will be.
-**
-** sys_init_time(), will return the clock resolution in MS and
-** that's about it. More could be added of course
-** If the clock-rate is constant (i.e. 1 ms) one can define
-** SYS_CLOCK_RESOLUTION (to 1),
-** which makes erts_deliver_time/erts_time_remaining a bit faster.
-**
-** if HAVE_GETHRTIME is defined:
-** sys_gethrtime() will return a SysHrTime (long long) representing
-** nanoseconds, sys_init_hrtime() will do any initialization.
-** else
-** a long (64bit) integer type called Sint64 should be defined.
-**
-** sys_times() will return clock_ticks since start and
-** fill in a SysTimes structure (struct tms). Instead of CLK_TCK,
-** SYS_CLK_TCK is used to determine the resolution of kernel ticks.
-**
-** sys_gettimeofday() will take a SysTimeval (a struct timeval) as parameter
-** and fill it in as gettimeofday(X,NULL).

+ * FUTURE CHANGES:
+ *
+ * The timestamp functionality has intentionally been
+ * split in two parts for future use even though it
+ * is not used like this today. take_timestamp() takes
+ * the timestamp and calculate heap need for it (which
+ * is not constant). write_timestamp() writes the
+ * timestamp to the allocated heap. That is, one typically
+ * want to take the timestamp before allocating the heap
+ * and then write it to the heap.
+ *
+ * The trace output functionality now use patch_ts_size(),
+ * write_ts(), and patch_ts(). write_ts() both takes the
+ * timestamp and writes it. Since we don't know the
+ * heap need when allocating the heap area we need to
+ * over allocate (maximum size from patch_ts_size()) and
+ * then potentially (often) shrink the heap area after the
+ * timestamp has been written. The only reason it is
+ * currently done this way is because we do not want to
+ * make major changes of the trace behavior in a patch.
+ * This is planned to be changed in next major release.
