2019-05-31Use UNALIGNED_MEMBER_PTRNobuyoshi Nakada
* internal.h (UNALIGNED_MEMBER_ACCESS, UNALIGNED_MEMBER_PTR): moved from eval_intern.h. * compile.c iseq.c, vm.c: use UNALIGNED_MEMBER_PTR for `entries` in `struct iseq_catch_table`. * vm_eval.c, vm_insnhelper.c: use UNALIGNED_MEMBER_PTR for `body` in `rb_method_definition_t`.
2019-05-29Fix Possible Control flow issues (DEADCODE)Kazuhiro NISHIYAMA
Coverity Scan says `Execution cannot reach this statement: "poison_object(v);"`, so do nothing when `ptr` is always 0 without address_sanitizer.

The function will return new or existing locations depending on whether or not the object actually moved, so give it a more appropriate name.

2019-04-22Symbols can move, so don't cache in static pointerAaron Patterson
This changes the static pointers to use IDs then look up the symbols with the ID. Symbols can move, so we don't want to keep static references to them.

2018-12-06Return same ISeq object for one src.ko1
* iseq.c: before this patch, RubyVM::InstructionSequence.of(src) (ISeq in short) returns different ISeq (wrapper) objects point to one ISeq internal object. This patch changes this behavior to cache created ISeq (wrapper) objects and return same ISeq object for an internal ISeq object. * iseq.h (ISEQ_EXECUTABLE_P): introduced to check executable ISeq objects. * iseq.h (ISEQ_COMPILE_DATA_ALLOC): reordr setting flag line to avoid ISEQ_USE_COMPILE_DATA but compiled_data == NULL case. * vm_core.h (rb_iseq_t): introduce `rb_iseq_t::wrapper` and `rb_iseq_t::aux::exec`. Move `rb_iseq_t::local_hooks` to `rb_iseq_t::aux::exec::local_hooks`. * test/ruby/test_iseq.rb: add ISeq.of() tests. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@66246 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2018-11-26Support targetting TracePoint [Feature #15289]ko1
* vm_trace.c (rb_tracepoint_enable_for_target): support targetting TracePoint. [Feature #15289] Tragetting TracePoint is only enabled on specified method, proc and so on, example: `tp.enable(target: code)`. `code` should be consisted of InstructionSeuqnece (iseq) (RubyVM::InstructionSeuqnece.of(code) should not return nil) If code is a tree of iseq, TracePoint is enabled on all of iseqs in a tree. Enabled tragetting TracePoints can not enabled again with and without target. * vm_core.h (rb_iseq_t): introduce `rb_iseq_t::local_hooks` to store local hooks. `rb_iseq_t::aux::trace_events` is renamed to `global_trace_events` to contrast with `local_hooks`. * vm_core.h (rb_hook_list_t): add `rb_hook_list_t::running` to represent how many Threads/Fibers are used this list. If this field is 0, nobody using this hooks and we can delete it. This is why we can remove code from cont.c. * vm_core.h (rb_vm_t): because of above change, we can eliminate `rb_vm_t::trace_running` field. Also renamed from `rb_vm_t::event_hooks` to `global_hooks`. * vm_core.h, vm.c (ruby_vm_event_enabled_global_flags): renamed from `ruby_vm_event_enabled_flags. * vm_core.h, vm.c (ruby_vm_event_local_num): added to count enabled targetting TracePoints. * vm_core.h, vm_trace.c (rb_exec_event_hooks): accepts hook list. * vm_core.h (rb_vm_global_hooks): added for convinience. * method.h (rb_method_bmethod_t): added to maintain Proc and `rb_hook_list_t` for bmethod (defined by define_method). * prelude.rb (TracePoint#enable): extracet a keyword parameter (because it is easy than writing in C). It calls `TracePoint#__enable` internal method written in C. * vm_insnhelper.c (vm_trace): check also iseq->local_hooks. * vm.c (invoke_bmethod): check def->body.bmethod.hooks. * vm.c (hook_before_rewind): check iseq->local_hooks and def->body.bmethod.hooks before rewind by exception. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@66003 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2018-10-20ext/coverage/: add the oneshot modemame
This patch introduces "oneshot_lines" mode for `Coverage.start`, which checks "whether each line was executed at least once or not", instead of "how many times each line was executed". A hook for each line is fired at most once, and after it is fired, the hook flag was removed; it runs with zero overhead. See [Feature #15022] in detail. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@65195 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

This table can be used to simplify trace instrumentation. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64518 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

Seprate this checking code from `finish_iseq_build()` and make new function. `iseq_ibf_load()` calls this funcation after loading. * test/ruby/test_iseq.rb: add a test for this fix. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64514 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2018-08-22parse.y: remove coverage-related code fragmentsmame
The code fragments that initializes coverage data were scattered into both parse.y and compile.c. parse.y allocated a coverage data, and compile.c initialize the data. To remove this cross-cutting concern, this change moves the allocation from "coverage" function of parse.y to "rb_iseq_new_top" of iseq.c. For the sake, parse.y just counts the line number of the original source code, and the number is passed via rb_ast_body_t. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64508 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2018-08-22thread.c (rb_reset_coverages): remove coverage counters from all ISeqsmame
When coverage measurement is enabled, the compiler makes each iseq have a reference to the counter array of coverage. Even after coverage measurement is disabled, the reference is kept. And, if coverage measurement is restarted, a coverage hook will increase the counter. This is completely meaningless; it brings just overhead. To remove this meaninglessness, this change removes all the reference when coverage measuement is stopped. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64504 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
