ko1 9f60791a04 * vm_core.h: revisit the structure of frame, block and env.
[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.

ko1 d5ec9ec308 * vm_core.h: split rb_call_info_t into several structs.
* rb_call_info (ci) has compiled fixed information.
  * if ci->flag & VM_CALL_KWARG, then rb_call_info is
    also rb_call_info_with_kwarg. This technique reduce one word
    for major rb_call_info data.
  * rb_calling_info has temporary data (argc, blockptr, recv).
    for each method dispatch. This data is allocated only on
    machine stack.
  * rb_call_cache is for inline method cache.
  Before this patch, only rb_call_info_t data is passed.
  After this patch, above three structs are passed.
  This patch improves:
  * data locarity (rb_call_info is now read-only data).
  * reduce memory consumption (rb_call_info_with_kwarg,
    rb_calling_info).
* compile.c: use above data.
* insns.def: ditto.
* iseq.c: ditto.
* vm_args.c: ditto.
* vm_eval.c: ditto.
* vm_insnhelper.c: ditto.
* vm_insnhelper.h: ditto.
* iseq.h: add iseq_compile_data::ci_index and
  iseq_compile_data::ci_kw_indx.
* tool/instruction.rb: introduce TS_CALLCACHE operand type.

ko1 e4198a73d4 * make rb_iseq_t T_IMEMO object (type is imemo_iseq).
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

ko1 5e8a147480 * method.h: introduce rb_callable_method_entry_t to remove
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.

* 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

ko1 ef25be7391 * vm_core.h: change semantics of opt_num and opt_table.
`opt_num' was the number of optional parameters + 1.
  `opt_table' has "opt_num" entries.
  Change them to:
  `opt_num' is the number of optional parameters.
  `opt_talbe' has "opt_num + 1" entries.
  This change simplify parameter fitting logics.
* compile.c: catch up this change.
* iseq.c: ditto.
* proc.c: ditto.
* vm_args.c: ditto.

ko1 831e33c780 * vm_core.h: change iseq parameter data structure.
https://bugs.ruby-lang.org/issues/10440#change-49694
  * change terminology `arg' to `param'.
  * move rb_iseq_t::arg_* to rb_iseq_t::param.
  * move rb_iseq_t::arg_size to rb_iseq_t::param::size.
  * move rb_iseq_t::argc to rb_iseq_t::param::lead_num.
  * move rb_iseq_t::arg_opts to rb_iseq_t::param::opt_num.
  * move rb_iseq_t::arg_rest to rb_iseq_t::param::rest_start.
  * move rb_iseq_t::arg_post_num to rb_iseq_t::param::post_num.
  * move rb_iseq_t::arg_post_start to rb_iseq_t::param::post_start.
  * move rb_iseq_t::arg_block to rb_iseq_t::param::block_start.
  * move rb_iseq_t::arg_keyword* to rb_iseq_t::param::keyword.
    rb_iseq_t::param::keyword is allocated only when keyword
    parameters are available.
  * introduce rb_iseq_t::param::flags to represent parameter
    availability. For example, rb_iseq_t::param:🎏:has_kw
    represents that this iseq has keyword parameters and
    rb_iseq_t::param::keyword is allocated.
    We don't need to compare with -1 to check availability.
  * remove rb_iseq_t::arg_simple.
* compile.c: catch up this change.
* iseq.c: ditto.
* proc.c: ditto.
* vm.c, vm_args.c, vm_dump.c, vm_insnhelper.c: ditto.
* iseq.c (iseq_data_to_ary): support keyword argument.

ko1 fbebd502f9 * rewrite method/block parameter fitting logic to optimize
keyword arguments/parameters and a splat argument.
  [Feature #10440] (Details are described in this ticket)
  Most of complex part is moved to vm_args.c.
  Now, ISeq#to_a does not catch up new instruction format.
* vm_core.h: change iseq data structures.
  * introduce rb_call_info_kw_arg_t to represent keyword arguments.
  * add rb_call_info_t::kw_arg.
  * rename rb_iseq_t::arg_post_len to rb_iseq_t::arg_post_num.
  * rename rb_iseq_t::arg_keywords to arg_keyword_num.
  * rename rb_iseq_t::arg_keyword to rb_iseq_t::arg_keyword_bits.
    to represent keyword bitmap parameter index.
    This bitmap parameter shows that which keyword parameters are given
    or not given (0 for given).
    It is refered by `checkkeyword' instruction described bellow.
  * rename rb_iseq_t::arg_keyword_check to rb_iseq_t::arg_keyword_rest
    to represent keyword rest parameter index.
  * add rb_iseq_t::arg_keyword_default_values to represent default
    keyword values.
  * rename VM_CALL_ARGS_SKIP_SETUP to VM_CALL_ARGS_SIMPLE
    to represent
      (ci->flag & (SPLAT|BLOCKARG)) &&
      ci->blockiseq == NULL &&
      ci->kw_arg == NULL.
* vm_insnhelper.c, vm_args.c: rewrite with refactoring.
  * rewrite splat argument code.
  * rewrite keyword arguments/parameters code.
  * merge method and block parameter fitting code into one code base.
* vm.c, vm_eval.c: catch up these changes.
* compile.c (new_callinfo): callinfo requires kw_arg parameter.
* compile.c (compile_array_): check the last argument Hash object or
  not. If Hash object and all keys are Symbol literals, they are
  compiled to keyword arguments.
* insns.def (checkkeyword): add new instruction.
  This instruction check the availability of corresponding keyword.
  For example, a method "def foo k1: 'v1'; end" is cimpiled to the
  following instructions.
    0000 checkkeyword     2, 0  # check k1 is given.
    0003 branchif         9     # if given, jump to address #9
    0005 putstring        "v1"
    0007 setlocal_OP__WC__0 3   # k1 = 'v1'
    0009 trace            8
    0011 putnil
    0012 trace            16
    0014 leave
* insns.def (opt_send_simple): removed and add new instruction
  "opt_send_without_block".
* parse.y (new_args_tail_gen): reorder variables.
  Before this patch, a method "def foo(k1: 1, kr1:, k2: 2, **krest, &b)"
  has parameter variables "k1, kr1, k2, &b, internal_id, krest",
  but this patch reorders to "kr1, k1, k2, internal_id, krest, &b".
  (locate a block variable at last)
* parse.y (vtable_pop): added.
  This function remove latest `n' variables from vtable.
* iseq.c: catch up iseq data changes.
* proc.c: ditto.
* class.c (keyword_error): export as rb_keyword_error().
* common.mk: depend vm_args.c for vm.o.
* hash.c (rb_hash_has_key): export.
* internal.h: ditto.
