* cont.c : Introdule ensure rollback mechanism. Please see below.

2013-11-15T17:15:31+00:00

	* internal.h (ruby_register_rollback_func_for_ensure): catch up above change.
	  Add rollback mechanism API.

	* vm_core.h (typedef struct rb_vm_struct): catch up above change.
	  Introdule ensure-rollback relation table.

	* vm_core.h (typedef struct rb_thread_struct): catch up above change.
	  Introdule ensure stack.

	* eval.c (rb_ensure): catch up above change.
	  Introdule ensure stack.

	* hash.c : New function for rollback ensure, and register it to
	  ensure-rollback relation table. [ruby-dev:47803] [Bug #9105]

	Ensure Rollback Mechanism:
	A rollback's function is a function to rollback a state before ensure's
	function execution.
	When the jump of callcc is across the scope of rb_ensure,
	ensure's functions and rollback's functions are executed appropriately
	for keeping consistency.

	Current API is unstable, and only internal use.

	ruby_register_rollback_func_for_ensure(ensure_func,rollback_func)
	This API create relation ensure's function to rollback's function.
	By registered rollback's function, it is executed When jumpping into
	corresponding rb_ensure scope.

eval.c: refactor exception cause

2013-11-15T14:08:49+00:00

* eval.c (setup_exception): set up cause after exception to be raised
  is fixed.  [Feature #8257]

* insns.def, vm.c, vm_insnhelper.c, vm_insnhelper.h, vm_method.c: split

2013-10-29T00:52:38+00:00

  ruby_vm_global_state_version into two separate counters - one for the
  global method state and one for the global constant state. This means
  changes to constants do not affect method caches, and changes to
  methods do not affect constant caches. In particular, this means
  inclusions of modules containing constants no longer globally
  invalidate the method cache.

* class.c, eval.c, include/ruby/intern.h, insns.def, vm.c, vm_method.c:
  rename rb_clear_cache_by_class to rb_clear_method_cache_by_class

* class.c, include/ruby/intern.h, variable.c, vm_method.c: add
  rb_clear_constant_cache

* compile.c, vm_core.h, vm_insnhelper.c: rename vmstat field in
  rb_call_info_struct to method_state

* vm_method.c: rename vmstat field in struct cache_entry to method_state
