extern.

threadptr since the parameter is rb_thread_t*.
* vm_backtrace.c (rb_threadptr_backtrace_location_ary): ditto.

actually check its availability rather to check GCC's version.
* configure.in (WARN_UNUSED_RESULT): moved to here.
* configure.in (RUBY_FUNC_ATTRIBUTE): change function declaration
to return int rather than void, because it makes no sense for a
warn_unused_result attributed function to return void.
Funny thing however is that it also makes no sense for noreturn
attributed function to return int. So there is a fundamental
conflict between them. While I tested this, I confirmed both
GCC 6 and Clang 3.8 prefers int over void to correctly detect
necessary attributes under this setup. Maybe subject to change
in future.
* internal.h (UNINITIALIZED_VAR): renamed to MAYBE_UNUSED, then
moved to configure.in for the same reason we move
WARN_UNUSED_RESULT.
* configure.in (MAYBE_UNUSED): moved to here.
* internal.h (__has_attribute): deleted, because it has no use now.
* string.c (rb_str_enumerate_lines): refactor macro rename.

Most of case, RUBY_VM_NORMAL_ISEQ_P() is no

VM_FRAME_FLAG_CFRAME.

All contents of previous rb_iseq_t is in rb_iseq_t::body.
Remove rb_iseq_t::self because rb_iseq_t is an object.
RubyVM::InstructionSequence is wrapper object points T_IMEMO/iseq.
So RubyVM::ISeq.of(something) method returns different wrapper
objects but they point the same T_IMEMO/iseq object.
This patch is big, but most of difference is replacement of
iseq->xxx to iseq->body->xxx.
(previous) rb_iseq_t::compile_data is also located to
rb_iseq_t::compile_data.
It was moved from rb_iseq_body::compile_data.
Now rb_iseq_t has empty two pointers.
I will split rb_iseq_body data into static data and dynamic data.
* compile.c: rename some functions/macros.
Now, we don't need to separate iseq and iseqval (only VALUE).
* eval.c (ruby_exec_internal): `n' is rb_iseq_t (T_IMEMO/iseq).
* ext/objspace/objspace.c (count_imemo_objects): count T_IMEMO/iseq.
* gc.c: check T_IMEMO/iseq.
* internal.h: add imemo_type::imemo_iseq.
* iseq.c: define RubyVM::InstructionSequnce as T_OBJECT.
Methods are implemented by functions named iseqw_....
* load.c (rb_load_internal0): rb_iseq_new_top() returns
rb_iseq_t (T_IMEMO/iesq).
* method.h (rb_add_method_iseq): accept rb_iseq_t (T_IMEMO/iseq).
* vm_core.h (GetISeqPtr): removed because it is not T_DATA now.
* vm_core.h (struct rb_iseq_body): remove padding for
[Bug #10037][ruby-core:63721].
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@51327 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* internal.h, iseq.c (rb_iseq_klass): remove it because
rb_iseq_t::klass is removed.
* vm_insnhelper.c (vm_super_outside): do not see cfp->iseq, but
check callable method entry on a frame.
This fix simplify the logic to search super class.
* test/ruby/test_method.rb: support super() from Proc.
Now, [Bug #4881] and [Bug #3136] was solved.
* proc.c (rb_mod_define_method): catch up this change.
* vm.c (vm_define_method): ditto.
* vm_backtrace.c (rb_profile_frames): now, each `frame' objects
are rb_callable_method_entry_t data or iseq VALUEs.
This fix introduce minor compatibility issue that
rb_profile_frame_label() always returns
rb_profile_frame_base_label().
* test/-ext-/debug/test_profile_frames.rb: catch up this change.

rb_control_frame_t::klass.
[Bug #11278], [Bug #11279]
rb_method_entry_t data belong to modules/classes.
rb_method_entry_t::owner points defined module or class.
module M
def foo; end
end
In this case, owner is M.
rb_callable_method_entry_t data belong to only classes.
For modules, MRI creates corresponding T_ICLASS internally.
rb_callable_method_entry_t can also belong to T_ICLASS.
rb_callable_method_entry_t::defined_class points T_CLASS or
T_ICLASS.
rb_method_entry_t data for classes (not for modules) are also
rb_callable_method_entry_t data because it is completely same data.
In this case, rb_method_entry_t::owner == rb_method_entry_t::defined_class.
For example, there are classes C and D, and incldues M,
class C; include M; end
class D; include M; end
then, two T_ICLASS objects for C's super class and D's super class
will be created.
When C.new.foo is called, then M#foo is searcheed and
rb_callable_method_t data is used by VM to invoke M#foo.
rb_method_entry_t data is only one for M#foo.
However, rb_callable_method_entry_t data are two (and can be more).
It is proportional to the number of including (and prepending)
classes (the number of T_ICLASS which point to the module).
Now, created rb_callable_method_entry_t are collected when
the original module M was modified. We can think it is a cache.
We need to select what kind of method entry data is needed.
To operate definition, then you need to use rb_method_entry_t.
You can access them by the following functions.
* rb_method_entry(VALUE klass, ID id);
* rb_method_entry_with_refinements(VALUE klass, ID id);
* rb_method_entry_without_refinements(VALUE klass, ID id);
* rb_resolve_refined_method(VALUE refinements, const rb_method_entry_t *me);
To invoke methods, then you need to use rb_callable_method_entry_t
which you can get by the following APIs corresponding to the
above listed functions.
* rb_callable_method_entry(VALUE klass, ID id);
* rb_callable_method_entry_with_refinements(VALUE klass, ID id);
* rb_callable_method_entry_without_refinements(VALUE klass, ID id);
* rb_resolve_refined_method_callable(VALUE refinements, const rb_callable_method_entry_t *me);
VM pushes rb_callable_method_entry_t, so that rb_vm_frame_method_entry()
returns rb_callable_method_entry_t.
You can check a super class of current method by
rb_callable_method_entry_t::defined_class.
* method.h: renamed from rb_method_entry_t::klass to
rb_method_entry_t::owner.
* internal.h: add rb_classext_struct::callable_m_tbl to cache
rb_callable_method_entry_t data.
We need to consider abotu this field again because it is only
active for T_ICLASS.
* class.c (method_entry_i): ditto.
* class.c (rb_define_attr): rb_method_entry() does not takes
defiend_class_ptr.
* gc.c (mark_method_entry): mark RCLASS_CALLABLE_M_TBL() for T_ICLASS.
* cont.c (fiber_init): rb_control_frame_t::klass is removed.
* proc.c: fix `struct METHOD' data structure because
rb_callable_method_t has all information.
* vm_core.h: remove several fields.
* rb_control_frame_t::klass.
* rb_block_t::klass.
And catch up changes.
* eval.c: catch up changes.
* gc.c: ditto.
* insns.def: ditto.
* vm.c: ditto.
* vm_args.c: ditto.
* vm_backtrace.c: ditto.
* vm_dump.c: ditto.

Motivation and new data structure are described in [Bug #11203].
This patch also solve the following issues.
* [Bug #11200] Memory leak of method entries
* [Bug #11046] __callee__ returns incorrect method name in orphan
proc
* test/ruby/test_method.rb: add a test for [Bug #11046].
* vm_core.h: remvoe rb_control_frame_t::me. me is located at value
stack.
* vm_core.h, gc.c, vm_method.c: remove unlinked_method... codes
because method entries are simple VALUEs.
* method.h: Now, all method entries has own independent method
definititons. Strictly speaking, this change is not essential,
but for future changes.
* rb_method_entry_t::flag is move to rb_method_definition_t::flag.
* rb_method_definition_t::alias_count is now
rb_method_definition_t::alias_count_ptr, a pointer to the counter.
* vm_core.h, vm_insnhelper.c (rb_vm_frame_method_entry) added to
search the current method entry from value stack.
* vm_insnhelper.c (VM_CHECK_MODE): introduced to enable/disable
assertions.

use 0 for rb_data_type_t::reserved instead of NULL, since its type
may be changed in the future and possibly not a pointer type.

The order of making binding should be stack (frame) top to bottom.
[Bug #7635]
And also fix issue of collecting klass. Collecting klass is same
