* introduce `trace_events' info for iseq.ko12017-11-181-1/+1
| | | | | | | | | | | | | | | | | | | | | * 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

* Avoid usage of the magic number `(NODE*)-1`mame2017-11-041-3/+3
| | | | | | | | | | | | | 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

* Use NODE_CASE2 if case expressions don't existyui-knk2017-10-311-11/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | | | * 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

| | | | | | | | | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [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
