Please refer this ticket for details.
This change also introduces the following changes.
* Remove RGENGC_AGE2_PROMOTION and introduce object age (0 to 3).
Age can be count with FL_PROMOTE0 and FL_PROMOTE1 flags in
RBasic::flags (2 bit). Age == 3 objects become old objects.
* WB_PROTECTED flag in RBasic to WB_UNPROTECTED bitmap.
* LONG_LIVED bitmap to represent living objects while minor GCs
It specifies (1) Old objects and (2) remembered shady objects.
* Introduce rb_objspace_t::marked_objects which counts marked
objects in current marking phase. marking count is needed to
introduce incremental marking.
* rename mark related function and sweep related function to
gc_(marks|sweep)_(start|finish|step|rest|continue).
* rename rgengc_report() to gc_report().
* Add obj_info() function to get cstr of object details.
* Add MEASURE_LINE() macro to measure execution time of specific line.
* and many small fixes.
* include/ruby/ruby.h: add flag USE_RINCGC.
Now USE_RINCGC can be set only with USE_RGENGC.
* include/ruby/ruby.h: introduce FL_PROMOTED0 and add FL_PROMOTED1
to count object age.
* include/ruby/ruby.h: rewrite write barriers for incremental marking.
* debug.c: catch up flag name changes.
* internal.h: add rb_gc_writebarrier_remember() instead of
rb_gc_writebarrier_remember_promoted().

Shared arrays were WB-unprotected object because
sharing array can modify shared array's buffer
if it occupied shared array.
[sharing array (ary)] -> [shared array (shared)] -> <buff>
| A
+---------------------------------------+
write `buff' with WB(ary, &buff[i], obj)
-> if `ary' and `shared' are old, then only `ary'
will be remembered.
-> traverse from `ary'. But `shared' is old, so
that written `obj' is not marked.
It cause WB miss so that shared arrays were WB-unprotected.
(WB-unprotected objects are marked everytime if it is living)
This patch insert WB() for `shared' if it is needed.

promoted. All objects referred from shared array should be marked

* configure.in (isinf, isnan): isinf() and isnan() are macros on
DragonFly which cannot be found by AC_REPLACE_FUNCS(). This
workaround enforces the fact that they exist on DragonFly.

* array.c: speedup Array#unshift by using space in shared array.
[Feature #6638]
- when array owns its shared array (ARY_SHARED_NUM == 1), and there
is enough space then try unshift values directly into shared
array.
- when resulting array is big (~>64 items) then make it shared with
enough room for future #unshifts, and then insert into shared
array.

* array.c (rb_ary_splice): use shared array in rb_ary_slice.
[Feature #6638]
- use ary_ensure_room_for_push when rb_ary_slice used to add at the
end of array, cause rb_ary_concat use rb_ary_slice.

* array.c (ary_ensure_room_for_push): make array really suitable for
queue. [Feature #6638]
when array is shared (which happens after Array#shift), and
ARY_SHARED_NUM == 1 (which is very often when array used as queue),
then make rb_ary_push push directly into shared array.
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@37582 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* array.c (rb_ary_modify): steal shared array's container when
ARY_SHARED_NUM == 1. [Feature #6638]
- Do not allocate new memory in rb_ary_modify when ARY_SHARED_NUM == 1
and length almost same.
- Store ARY_CAPA instead of RARRAY_LEN in ary_make_shared, to make
it useful.
- Fix rb_ary_sort_bang accordantly.

precision of long may be larger than double.

We talked about this and it is like following:
* maybe ary.join(nil) should always use empty string as a separator,
but it disables to specify $, as a seprator through variables.
* if nil means '', the conversion is to_s. to_s is not accepted.
* nil is a special value, so special behavior is allowed.
* use of $ variables is not recommended, so it is not worth to change
current behavior.
