2015-09-19* vm_core.h: split rb_call_info_t into several structs.ko1
* 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. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@51903 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

variables here. vm_push_frame() clears. * vm_insnhelper.c (vm_call_iseq_setup_tailcall): ditto. * vm_insnhelper.c (vm_push_frame): move check code to vm_check_frame(). Reorder initialization timing to reuse same values (sp). * compile.c (rb_iseq_compile_node): use iseq_set_exception_local_table() for ISEQ_TYPE_DEFINED_GUARD. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@51846 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2015-09-10compile.c: register cdhashnobu
* compile.c (iseq_build_from_ary_body): register cdhash to the iseq constant body instead of compile time mark array, not to get GCed. [ruby-core:70708] [Feature #8543] git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@51816 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2015-08-21* vm_opts.h, iseq.c, iseq.h: add compile option to force frozenko1
string literals. [Feature #11473] This addition is not specification change, but to try frozen string literal world discussed on [Feature #11473]. You can try frozen string literal world using this magical line: RubyVM::InstructionSequence.compile_option = {frozen_string_literal: true} Note that this is a global compilation option, so that you need to compile another script like that: p 'foo'.frozen? #=> false RubyVM::InstructionSequence.compile_option = {frozen_string_literal: true} p 'foo'.frozen? #=> false, because this line is already compiled. p eval("'foo'.frozen?") #=> true Details: * String literals are deduped by rb_fstring(). * Dynamic string literals ("...#{xyz}...") is now only frozen, not deduped. Maybe you have other ideas. Now, please do not use this option on your productions :) Of course, current specification can be changed. * compile.c: ditto. * test/ruby/test_iseq.rb: add a test. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@51659 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2015-07-21* make rb_iseq_t T_IMEMO object (type is imemo_iseq).ko1
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
