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.

* object.c (rb_obj_itself): new method Object#itsef. based on the
patch by Rafael França in [ruby-core:64156].
[EXPERIMENTAL] this method may be renamed due to compatibilities.

exposing IDs from collectable symbols.
[Bug #10014]
Now, rb_check_id() returns 0 if corresponding symbol is
pinned dynamic symbol.
There is remaining intern_cstr_without_pindown(), it can return
IDs from collectable symbols. We must be careful to use it
(only used in parse.y). I think it should be removed if
it does not have impact for performance.
* parse.y:
add:
* STATIC_SYM2ID()
* STATIC_ID2SYM()
rename:
* rb_pin_dynamic_symbol() -> dsymbol_pindown()
* internal.h:
remove:
* rb_check_id_without_pindown()
* rb_sym2id_without_pindown()
add:
* rb_check_symbol()
* rb_check_symbol_cstr()
* load.c: use rb_check_id() or rb_check_id_cstr().
* object.c: ditto.
* struct.c: ditto.
* thread.c: ditto.
* vm_method.c: ditto.
* string.c (sym_find): use only rb_check_symbol().
* sprintf.c (rb_str_format): use rb_check_symbol_cstr().

See this ticket about Symbol GC.
* include/ruby/ruby.h:
Declare few functions.
* rb_sym2id: almost same as old SYM2ID but support dynamic symbols.
* rb_id2sym: almost same as old ID2SYM but support dynamic symbols.
* rb_sym2str: almost same as `rb_id2str(SYM2ID(sym))` but not
pin down a dynamic symbol.
Declare a new struct.
* struct RSymbol: represents a dynamic symbol as object in
Ruby's heaps.
Add few macros.
* STATIC_SYM_P: check a static symbol.
* DYNAMIC_SYM_P: check a dynamic symbol.
* RSYMBOL: cast to RSymbol
* gc.c: declare RSymbol. support T_SYMBOL.
* internal.h: Declare few functions.
* rb_gc_free_dsymbol: free up a dynamic symbol. GC call this
function at a sweep phase.
* rb_str_dynamic_intern: convert a string to a dynamic symbol.
* rb_check_id_without_pindown: not pinning function.
* rb_sym2id_without_pindown: ditto.
* rb_check_id_cstr_without_pindown: ditto.
* string.c (Init_String): String#intern and String#to_sym use
rb_str_dynamic_intern.
* template/id.h.tmpl: use LSB of ID as a flag for determining a
static symbol, so we shift left other ruby_id_types.
* string.c: use rb_sym2str instead `rb_id2str(SYM2ID(sym))` to
avoid pinning.
* load.c: use xx_without_pindown function at creating temporary ID
to avoid pinning.
* object.c: ditto.
* sprintf.c: ditto.
* struct.c: ditto.
* thread.c: ditto.
* variable.c: ditto.

constify a parameter (VALUE *).
I believe this incompatibility doesn't break any code.
However, if you have trouble, please tell us.

The #== method was hidden in ri/rdoc's output and was highlighting
the line instead.

* include/ruby/ruby.h (struct RClass): add super, remove iv_index_tbl.
since RCLASS_SUPER() is commonly used inside while loops, we move it
back inside struct RClass to improve cache hits. this provides a
small improvement (1%) in hotspots like rb_obj_is_kind_of()
* internal.h (struct rb_classext_struct): remove super, add
iv_index_table
* internal.h (RCLASS_SUPER): update for new location
* internal.h (RCLASS_SET_SUPER): ditto
* internal.h (RCLASS_IV_INDEX_TBL): ditto
* object.c (rb_class_get_superclass): ditto
* include/ruby/backward/classext.h (RCLASS_SUPER): ditto

well as const_get. [Feature #7414]

* object.c (rb_mod_const_get): fix typo. should use SYM2ID() not
ID2SYM().
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@44192 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* object.c (rb_mod_const_get): already interned junk name may be
valid nested class path.
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@44190 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* object.c (rb_mod_const_get): Symbol must be the entire name, not
a nested constant path, so achieve by its ID directly.

* class.c (include_modules_at): use RCLASS_M_TBL_WRAPPER for
equality checks. this avoids an unnecessary deference inside a tight
loop, fixing a performance regression from r43973.
* object.c (rb_obj_is_kind_of): ditto.
* object.c (rb_class_inherited_p): ditto.

* object.c (Init_Object): undef Module#prepend_features on Class, as
well as Module#append_features. [Fixes GH-376]
* test_class.rb: Added test for above. And ensure type checking
on similar methods as module_function.
