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().
* array.c (ary_memcpy0): use rb_gc_writebarrier_remember().
* array.c (rb_ary_modify): ditto.
* hash.c (rb_hash_keys): ditto.
* hash.c (rb_hash_values): ditto.
* object.c (init_copy): use rb_copy_wb_protected_attribute() because
FL_WB_PROTECTED is moved from RBasic::flags.
* test/objspace/test_objspace.rb: catch up ObjectSpace.dump() changes.

ObjectSpace.reachable_objects_from_root returns all objects refered
from root (called "root objects").
This feature is for deep object analysis.
* test/objspace/test_objspace.rb: add a test.

"[ruby-core:55182] [ruby-trunk - Bug #8456][Open] Sugfault in Ruby Head"
Care about the case TracePoint#path #=> `nil'.
* ext/objspace/object_tracing.c: add two new methods:
* ObjectSpace.allocation_class_path(o)
* ObjectSpace.allocation_method_id(o)
They are not useful for Object.new because they are always
"Class" and :new.
To trace more useful information, we need to maintain call-tree
using call/return hooks, which is implemented by
ll-prof <http://sunagae.net/wiki/doku.php?id=software:llprof>
* test/objspace/test_objspace.rb: add a test.

Read the following test to know HOWTO.
This feature is a sample of RUBY_INTERNAL_EVENT.
* test/objspace/test_objspace.rb: add a test.
* ext/objspace/object_tracing.c: ditto.
* gc.c (rb_gc_count): add. THis function returns GC count.
* internal.h: add decl. of rb_gc_count(). Same as `GC.count'.

This method returns an array of objects referenced by given object.
If given object is special objects such as true/false/nil/Fixnum etc
then it returns nil. See rdoc for details.
[ruby-core:39772]
* test/objspace/test_objspace.rb: add a test for this method.
* gc.c: add rb_objspace_reachable_objects_from().
To make this function, add several member `mark_func_data'
to rb_objspace_t. If mark_func_data is not null, then
gc_mark() calls mark_func_data::mark_func.
* gc.h: export rb_objspace_reachable_objects_from().
