* trace.h: new file. wraps tracing mechanisms.
* defs/dtrace.d: new file. defined a dtrace provider "ruby". * include/ruby/ruby.h (LIKELY): moved from vm.c. (UNLIKELY): ditto. (OBJSETUP): probe "object-create". (RUBY_EVENT_RESCUE): new event. * vm_exec.c (DEBUG_ENTER_INSN): embeded a probe insn-entry into it. (DEBUG_END_INSN): insn-return. * vm.c (LIKELY): moved into ruby.h. (UNLIKELY): ditto. (Init_BareVM): embeded a probe "raise" into it. * variable.c (rb_class2name_without_alloc): new utility function. * tool/rbinstall.rb (install?(:ext, :arch, :'ext-arch')): installs dtrace.d if necessary. * thread_pthread.c (add_signal_thread_list): probe "raise". (rb_thread_create_timer_thread): ditto. * thread.c (rb_thread_schedule_rec): probes "thread-enter" and "thread-leave", (thread_start_func_2): ditto. (thread_cleanup_func): probe "thread-term" * lib/mkmf.rb: supports dtrace postprocessor on making an extension. * iseq.c (rb_vm_insn_name): new utility function. (rb_vm_insn_len): ditto. * insns.def (hook): probes "method-etnry", "method-return", "line", and "rescue". * compile.c (iseq_compile_each): adds a trace op for "rescue" probe. * gc.c (garbage_collect): probes "gc-begin" and "gc-end". (obj_free): probe "object-free" (garbage_collect_with_gvl): probe "raise" (negative_size_allocation_error): ditto. (rb_memerror): ditto. * eval.c (rb_rescue2): probe "rescue" (rb_longjmp): probe "raise" * ext/probe/probe.c: new extension for application defined probes. * ext/probe/extconf.rb: ditto. * configure.in (--with-tracing-model): new option to choose a tracing mechanism. (DTRACE): new substitution. name of dtrace(1). (RUBY_TRACING_MODEL): new substitution. (DTRACE_OBJ): ditto. (MINIDTRACE_OBJ): ditto. (GOLFDTRACE_OBJ): ditto. (LIBRUBY_DTRACE_OBJ): ditto. (RUBY_DTRACE_POSTPROCESS): new macro. checks whether the dtrace on the system needs postprocessing. (RUBY_DTRACE_BSD_BROKEN): new macro. checks whether the dtrace supports USDT. * Makefile.in: (DTRACE): new variable. name of dtrace(1). (TRACING_MODEL): new variable. name of the chosen tracing mechanism. (DTRACE_OBJ): same as the one in configure.in. (MINIDTRACE_OBJ): ditto. (GOLFDTRACE_OBJ): ditto. (LIBRUBY_DTRACE_OBJ): ditto. (CPPOUTFILE): new substitution. necessary for generating dtrace.d (trace_none.h): new target for TRACING_MODEL=none (RUBY_H_INCLUDES): appended a header for tracing. (distclean-local): also removes preprocessed version of dtrace.d ($(LIBRUBY_A)): needs $(LIBRUBY_DTRACE_OBJ) if dtrace needs postprocessing. ($(PROGRAM)): ditto. (golf): ditto. (miniruby): ditto. ($(arch_hdrdir)/ruby/dtrace.d): new target. preprocessed verson of defs/dtrace.d. generated if necessary. ($(arch_hdrdir)/ruby/trace_dtrace.h): new target. definition of probes. ($(LIBRUBY_DTRACE_OBJ)): new target. generated if dtrace needs postprocessing. ($(DTRACE_OBJ)): ditto. ($(MINIDTRACE_OBJ)): ditto. ($(GOLFDTRACE_OBJ)): ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@26235 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
