* vm_core.h: remove lfp (local frame pointer) and rename dfp (dynamic frame pointer) to ep (environment pointer). This change make VM `normal' (similar to other interpreters). Before this commit: Each frame has two env pointers lfp and dfp. lfp points local environment which is method/class/toplevel frame. lfp[0] is block pointer. dfp is block local frame. dfp[0] points previous (parent) environment pointer. lfp == dfp when frame is method/class/toplevel. You can get lfp from dfp by traversing previous environment pointers. After this commit: Each frame has only `ep' to point respective enviornoment. If there is parent environment, then ep[0] points parent envioenment (as dfp). If there are no more environment, then ep[0] points block pointer (as lfp). We call such ep as `LEP' (local EP). We add some macros to get LEP and to detect LEP or not. In short, we replace dfp and lfp with ep and LEP. rb_block_t and rb_binding_t member `lfp' and `dfp' are removed and member `ep' is added. rename rb_thread_t's member `local_lfp' and `local_svar' to `root_lep' and `root_svar'.

* rewrite method/block parameter fitting logic to optimize keyword arguments/parameters and a splat argument.

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.

* 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. * 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

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. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@48239 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* vm_core.h: remove VM_FRAME_MAGIC_FINISH (finish frame type). Before this commit: `finish frame' was place holder which indicates that VM loop needs to return function. If a C method calls a Ruby methods (a method written by Ruby), then VM loop will be (re-)invoked. When the Ruby method returns, then also VM loop should be escaped. `finish frame' has only one instruction `finish', which returns VM loop function. VM loop function executes `finish' instruction, then VM loop function returns itself. With such mechanism, `leave' instruction (which returns one frame from current scope) doesn't need to check that this `leave' should also return from VM loop function. Strictly, one branch can be removed from `leave' instructon. Consideration: However, pushing the `finish frame' needs costs because it needs several memory accesses. The number of pushing `finish frame' is greater than I had assumed. Of course, pushing `finish frame' consumes additional control frame. Moreover, recent processors has good branch prediction, with which we can ignore such trivial checking. After this commit: Finally, I decide to remove `finish frame' and `finish' instruction. Some parts of VM depend on `finish frame', so the new frame flag VM_FRAME_FLAG_FINISH is introduced. If this frame should escape from VM function loop, then the result of VM_FRAME_TYPE_FINISH_P(cfp) is true. `leave' instruction checks this flag every time. I measured performance on it. However on my environments, it improves some benchmarks and slows some benchmarks down. Maybe it is because of C compiler optimization parameters. I'll re-visit here if this cause problems. * insns.def (leave, finish): remove finish instruction. * vm.c, vm_eval.c, vm_exec.c, vm_backtrace.c, vm_dump.c: apply above changes. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@36099 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
