  are imemo objects (imemo_env).

* NEWS: describe this change. I believe nobody touch these objects
  because there are no method defined.

* vm_core.h: remove the following definitions.
  * rb_cEnv decl.
  * GetEnvPtr() because Env is no longer T_DATA object.

* vm_core.h (rb_env_t): fix layout for imemo values.

* vm_core.h (vm_assert_env): added.

* vm_core.h (vm_env_new): added.

  [Bug #12628]

  This patch introduce many changes.

  * Introduce concept of "Block Handler (BH)" to represent
    passed blocks.

  * move rb_control_frame_t::flag to ep[0] (as a special local
    variable). This flags represents not only frame type, but also
    env flags such as escaped.

  * rename `rb_block_t` to `struct rb_block`.

  * Make Proc, Binding and RubyVM::Env objects wb-protected.

  Check [Bug #12628] for more details.

gc.c: running finalizer state

2016-07-26T13:43:38+00:00

* gc.c (run_finalizer): make saved running finalizer state
  volatile to ensure not to be clobbered by longjmp.

git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@55759 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* gc.c (gc_mark): add `inline' explicitly.

2016-07-26T09:57:50+00:00

  I expected to inline this function implicitly at the loop
  (ex: marking T_ARRAY objects) but sometimes it remains as
  normal call.

  protecting for each finalizer.

2016-07-21T21:12:53+00:00

* gc.c (gc_start_internal, rb_gc_start): set finalizing flag
  whenever calling deferred finalizers not to recurse.

* gc.c (gc_mark_roots): should mark the VM object itself to mark

2016-07-13T07:08:32+00:00

  singleton class of the VM object.
  Before this patch, we only set mark bit for the VM object and
  invoke mark function separately.
  [Bug #12583]

* test/ruby/test_gc.rb: add a test.
