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

* compile.c (iseq_peephole_optimize): do not need to put `pop` instruction. * test/ruby/test_optimization.rb (test_peephole_optimization_without_trace): This code "def foo; 1.times{|(a), &b| nil && a}; end" fails to compile by stack underflow because of above bug (fixed by this patch). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@60724 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2017-11-04Avoid usage of the magic number `(NODE*)-1`mame
This magic number has two meanings depending upon the context: * "required keyword argument (no name)" on NODE_LASGN (`def foo(x:)`) * "rest argument (no name)" on NODE_MASGN and NODE_POSTARG ('a, b, * = ary` or `a, b, *, z = ary`) To show this intention explicitly, two macros are introduced: NODE_SPECIAL_REQUIRED_KEYWORD and NODE_SPECIAL_NO_NAME_REST. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@60650 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2017-11-04compile.c (setup_args): Fix a typoyui-knk
* compile.c (setup_args): In this function, an argument of nd_line is argn except this line. And argn is a pointer of NODE. So I think this is a typo. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@60649 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2017-11-04Remove RNODE cast from NODE utility functionsmame
Now, casting NODE to VALUE is not recommended. This change requires an explicit cast from VALUE to NODE to use the NODE utility functions such as `nd_type`. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@60643 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2017-10-31Use NODE_CASE2 if case expressions don't existyui-knk
When NODE_WHEN is compiled by iseq_compile_each0, the node passed to compile_when is NODE_WHEN (not NODE_CASE). So we can not handle the location of NODE_CASE of case statements which don't have case expressions. e.g. : ``` case; when 1; foo; when 2; bar; else baz; end ``` This commit adds NODE_CASE2, and compiles it by iseq_compile_each0. * compile.c (compile_case): Does not call COMPILE_ when NODE_CASE does not have case expressions. * compile.c (compile_case2): Compile NODE_CASE2 by compile_case2. * compile.c (compile_when): Delete an obsoleted function. * compile.c (iseq_compile_each0): Compile NODE_CASE2. * ext/objspace/objspace.c (count_nodes): Add NODE_CASE2 case. * node.c (dump_node, rb_gc_mark_node): Add NODE_CASE2 case. * node.h (node_type): Add NODE_CASE2. * node.h (NEW_CASE2): Add a macro which generates NODE_CASE2. * parse.y: Generate NODE_CASE2 if case expressions don't exist. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@60585 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2017-10-30Use nd_lineno instead of nd_line for branch coveragesyui-knk
* compile.c (compile_if, compile_case, compile_loop, iseq_compile_each0): Use nd_lineno of nodes for branch coverages. nd_lineno is not adjusted line number of nodes. Sometimes nd_line is adjusted by fixpos. These adjustments lead to confusing result. For example, lineno of NODE_IF is 1, but line is 2 (line number is one-based). ``` ;;;;;;;;;;;;;;;;;;;;if 1 + 1 2 end ``` git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@60581 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2017-10-26some functions accept `ec` instead of `th`.ko1
* vm.c (vm_make_env_object): accepts `ec`. * vm.c (rb_vm_get_ruby_level_next_cfp): ditto. * vm.c (rb_vm_make_proc): ditto. * vm.c (rb_vm_make_proc_lambda): ditto. * vm_core.h: some macros accept ec instead of th (and make them inline functions): * RUBY_VM_CONTROL_FRAME_STACK_OVERFLOW * RUBY_VM_END_CONTROL_FRAME * RUBY_VM_CONTROL_FRAME_STACK_OVERFLOW_P * eval.c (frame_func_id): constify for the first parameter. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@60441 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2017-10-26Use rb_execution_context_t instead of rb_thread_tko1
to represent execution context [Feature #14038] * vm_core.h (rb_thread_t): rb_thread_t::ec is now a pointer. There are many code using `th` to represent execution context (such as cfp, VM stack and so on). To access `ec`, they need to use `th->ec->...` (adding one indirection) so that we need to replace them by passing `ec` instead of `th`. * vm_core.h (GET_EC()): introduced to access current ec. Also remove `ruby_current_thread` global variable. * cont.c (rb_context_t): introduce rb_context_t::thread_ptr instead of rb_context_t::thread_value. * cont.c (ec_set_vm_stack): added to update vm_stack explicitly. * cont.c (ec_switch): added to switch ec explicitly. * cont.c (rb_fiber_close): added to terminate fibers explicitly. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@60440 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2017-10-24Lazy Proc allocation for block parametersko1
[Feature #14045] * insns.def (getblockparam, setblockparam): add special access instructions for block parameters. getblockparam checks VM_FRAME_FLAG_MODIFIED_BLOCK_PARAM and if it is not set this instruction creates a Proc object from a given blcok and set VM_FRAME_FLAG_MODIFIED_BLOCK_PARAM. setblockparam is similar to setlocal, but set VM_FRAME_FLAG_MODIFIED_BLOCK_PARAM. * compile.c: use get/setblockparm instead get/setlocal instructions. Note that they are used for method local block parameters (def m(&b)), not for block local method parameters (iter{|&b|). * proc.c (get_local_variable_ptr): creates Proc object for Binding#local_variable_get/set. * safe.c (safe_setter): we need to create Proc objects for postponed block parameters when $SAFE is changed. * vm_args.c (args_setup_block_parameter): used only for block local blcok parameters. * vm_args.c (vm_caller_setup_arg_block): if called with VM_CALL_ARGS_BLOCKARG_BLOCKPARAM flag then passed block values should be a block handler. * test/ruby/test_optimization.rb: add tests. * benchmark/bm_vm1_blockparam*: added. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@60397 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2017-10-24Remove dynamic NODE allocation out of parsermame
