* * make rb_iseq_t T_IMEMO object (type is imemo_iseq).ko12015-07-211-11/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* * method.h: introduce rb_callable_method_entry_t to removeko12015-07-031-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. * vm_eval.c: ditto. * vm_insnhelper.c: ditto. * vm_method.c: ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@51126 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

| | | | | | | | | | | | | | | | | | | | | | | | | | | Motivation and new data structure are described in [Bug #11203].

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. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@50728 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
