2018-01-09Rename code_range to code_locationmame
Because the name "code_range" is ambiguous with encoding's. Abbreviations ("crange", and "cr") are also renamed to "loc". The traditional "code_location" (a pair of lineno and column) is renamed to "code_position". Abbreviations are also renamed (first_loc to beg_pos, and last_loc to end_pos). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61721 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2018-01-04iseq.c: Refactor out rb_iseq_new_ifunc from rb_iseq_new_with_optmame
It is too error-prone to pass IMEMO_IFUNC object as NODE*. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61592 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2018-01-01iseq.h: Extract position array from iseq_insn_info_entrymame
This makes TracePoint a bit fast by reducing cache misses of `get_insn_info_binary_search`. Also, I plan to use succinct bitvector algorithm for `get_insn_info` instead of binary search. This change will make it easy. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61536 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2017-12-24Remove "trace_instruction" compile option.ko1
* iseq.h (rb_compile_option_struct): trace instruction is removed so that remove the trace_instruction compile option. Don't show warning (just ignore) for Ruby 2.5. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61450 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2017-12-06thread.c (update_line_coverage): Use RUBY_EVENT_LINEmame
This change makes coverage use the general event type RUBY_EVENT_LINE instead of a special event type RUBY_EVENT_COVERAGE. Just a refactoring. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61043 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2017-12-05Revamp method coverage to support define_methodmame
Traditionally, method coverage measurement was implemented by inserting `trace2` instruction to the head of method iseq. So, it just measured methods defined by `def` keyword. This commit drastically changes the measuring mechanism of method coverage; at `RUBY_EVENT_CALL`, it keeps a hash from rb_method_entry_t* to runs (i.e., it counts the runs per method entry), and at `Coverage.result`, it creates the result hash by enumerating all `rb_method_entry_t*` objects (by `ObjectSpace.each_object`). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61023 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2017-11-18introduce `trace_events' info for iseq.ko1
* vm_core.h (rb_iseq_t::aux): add `trace_events` which represents which events are enabled on this iseq. With this information, we can skip useless trace-on changes for ISeqs. * vm_trace.c (RUBY_EVENTS_TRACE_BY_ISEQ): moved to iseq.h and rename it with ISEQ_TRACE_EVENTS. * iseq.h: introduce ISEQ_USE_COMPILE_DATA iseq (imemo) flag to represent COMPILE_DATA is available. In other words, iseq->aux.trace_events is not available when this flag is set. * ISEQ_COMPILE_DATA() is changed from a macro. * ISEQ_COMPILE_DATA_ALLOC() is added. * ISEQ_COMPILE_DATA_CLEAR() is added. * iseq.c: use them. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@60838 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2017-11-17remove `trace_` prefix insns lazily.ko1
* vm_trace.c (update_global_event_hook): set only when tracing is added. If tracing was off (event flags are decreased), then ignore them. Next `trace_` prefix instruction will trace off itself (lazy tracing off). * vm_insnhelper.c (vm_trace): trace-off for when trace is not needed. * iseq.c (rb_iseq_trace_set): fix trace-off process (it was never off tracing). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@60817 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2017-11-14remove `trace` instruction. [Feature #14104]ko1
* tool/instruction.rb: create `trace_` prefix instructions. * compile.c (ADD_TRACE): do not add `trace` instructions but add TRACE link elements. TRACE elements will be unified with a next instruction as instruction information. * vm_trace.c (update_global_event_hook): modify all ISeqs when hooks are enabled. * iseq.c (rb_iseq_trace_set): added to toggle `trace_` instructions. * vm_insnhelper.c (vm_trace): added. This function is a body of `trace_` prefix instructions. * vm_insnhelper.h (JUMP): save PC to a control frame. * insns.def (trace): removed. * vm_exec.h (INSN_ENTRY_SIG): add debug output (disabled). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@60763 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2017-11-14use RUBY_API_VERSION as ISEQ versions.ko1
* iseq.h: use RUBY_API_VERSION_MAJOR for ISEQ_MAJOR_VERSION and RUBY_API_VERSION_MINOR for ISEQ_MINOR_VERSION. We need to keep compatibility for ISeq during same major/minor versions. If we need to change compatibility between teeny versions, we should use (RUBY_API_VERSION_MINOR * 10 + iseq revs) for ISEQ_MINOR_VERSION. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@60758 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2017-09-03Refactor the internal data format for coverage measurementmame
To prepare new measuring targets: branch and method coverages. So far, iseq->coverage was an array of counts executed for line coverage. Now, it is a three-element array for each measuring target, whose first element is an array for line coverage. The second element is planned for branch coverage, and the third will be for method coverage. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@59738 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2017-06-08check break target correctly.ko1
* compile.c (iseq_compile_each0): save target child_iseq in the catch-table for break. This iseq is not for continuation, but for search key at vm_throw_start(). * vm_insnhelper.c (vm_throw_start): check saved iseq first. * iseq.h: add comment for it. * test/ruby/test_iterator.rb (test_ljump): add a test for the issue: def call b; b.call; end call(Proc.new{break}){} #=> (1) should raise LocalJumpError call(Proc.new{break}) #=> (2) shoudd raies LocalJumpError, too. but (1) doesn't raise LocalJumpError. This issue is reported by Matz. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@59043 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2017-06-01rename absolute_path to realpath internally and introduce pathobj.ko1
* vm_core.h: rename absolute_path to realpath because it is expected name. external APIs (#absolute_path methods) are remained. * vm_core.h: remove rb_iseq_location_struct::path and rb_iseq_location_struct::absolute_path and introduce pathobj. if given path equals to given absolute_path (and most of case it is true), pathobj is simply given path String. If it is not same, pathobj is Array and pathobj[0] is path and pathobj[1] is realpath. This size optimization reduce 8 bytes and sizeof(struct rb_iseq_constant_body) is 200 bytes -> 192 bytes on 64bit CPU. To support this change, the following functions are introduced: * pathobj_path() (defined in vm_core.h) * pathobj_realpath() (ditto) * rb_iseq_path() (decl. in vm_core.h) * rb_iseq_realpath() (ditto) * rb_iseq_pathobj_new() (ditto) * rb_iseq_pathobj_set() (ditto) * vm_core.h (rb_binding_t): use pathobj instead of path. If binding is given at eval methods, realpath (absolute_path) was caller's realpath. However, they should use binding's realpath. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@58979 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2016-05-14* iseq.h (struct iseq_compile_data): use struct rb_id_tablenaruse
instead of st_table. * iseq.c (prepare_iseq_build): don't allocate ivar_cache_table until it has at least one element. * iseq.c (compile_data_free): free ivar_cache_table only if it is allocated. * compile.c (get_ivar_ic_value): allocate if the table is not allocated yet. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@55002 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2015-12-08* introduce new ISeq binary format serializer/de-serializerko1
and a pre-compilation/runtime loader sample. [Feature #11788] * iseq.c: add new methods: * RubyVM::InstructionSequence#to_binary_format(extra_data = nil) * RubyVM::InstructionSequence.from_binary_format(binary) * RubyVM::InstructionSequence.from_binary_format_extra_data(binary) * compile.c: implement body of this new feature. * load.c (rb_load_internal0), iseq.c (rb_iseq_load_iseq): call RubyVM::InstructionSequence.load_iseq(fname) with loading script name if this method is defined. We can return any ISeq object as a result value. Otherwise loading will be continue as usual. This interface is not matured and is not extensible. So that we don't guarantee the future compatibility of this method. Basically, you should'nt use this method. * iseq.h: move ISEQ_MAJOR/MINOR_VERSION (and some definitions) from iseq.c. * encoding.c (rb_data_is_encoding), internal.h: added. * vm_core.h: add several supports for lazy load. * add USE_LAZY_LOAD macro to specify enable or disable of this feature. * add several fields to rb_iseq_t. * introduce new macro rb_iseq_check(). * insns.def: some check for lazy loading feature. * vm_insnhelper.c: ditto. * proc.c: ditto. * vm.c: ditto. * test/lib/iseq_loader_checker.rb: enabled iff suitable environment variables are provided. * test/runner.rb: enable lib/iseq_loader_checker.rb. * sample/iseq_loader.rb: add sample compiler and loader. $ ruby sample/iseq_loader.rb [dir] will compile all ruby scripts in [dir]. With default setting, this compile creates *.rb.yarb files in same directory of target .rb scripts. $ ruby -r sample/iseq_loader.rb [app] will run with enable to load compiled binary data. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@52949 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2015-12-02* vm_core.h, iseq.h: remove rb_iseq_t::variable_body.ko1
Fields in rb_iseq_t::variable_body are contained by rb_iseq_t::body::mark_ary (hidden Array object). Index 0 to 2 of mark_ary are reserved by these objects. * iseq.c: catch up this fix. * compile.c (rb_iseq_original_iseq): trivial rewrite. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@52865 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

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

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.

2014-07-26struct iseq_compile_data_storage: 16 bytes (from 32) overheadnormal
This reduces the iseq_compile_data_storage header from 32 to 16 bytes on 64-bit systems. pos and size fields cannot exceed 32-bit sizes due to stack size limits. Using a flexible array for the buffer also saves us 8 bytes of pointer overhead. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@46958 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
