| | | | | | | | | | | | | | It seems like leftover development step from r59557 ("refactoring Fiber status"). I will make fiber_status use BITFIELD macro in a future commit. * cont.c (struct rb_fiber_struct): drop const from fiber_status (fiber_status_set): remove cast [ruby-core:86788] [Misc #14720] git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@63315 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* refactoring r63073.ko12018-04-041-30/+11
| | | | | | | | | | | | | | * cont.c (root_fiber_alloc): call `ConvertThreadToFiber()` here. `rb_fiber_t` for root_fiber is allocated before running Threads. Fiber objects wrapping this rb_fiber_t for root_fiber are created when root Fiber object is required explicitly (for example, Fiber switching and so on). We can put calling `ConvertThreadToFiber()`. In other words, we can pending `ConvertThreadToFiber()` until Fiber objects are created. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@63090 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* Fix Fiber with Thread issue on Windows [Bug #14642]ko12018-04-031-3/+25
| | | | | | | | | | | | | | | | | | | | | | | | * cont.c (rb_threadptr_root_fiber_setup): divide into two functions: * rb_threadptr_root_fiber_setup_by_parent(): called by the parent thread. * rb_threadptr_root_fiber_setup_by_child(): called by the created thread. `rb_threadptr_root_fiber_setup()` is called by the parent thread and set fib->fib_handle by ConvertThreadToFiber() on the parent thread on Windows enveironment. This means that root_fib->fib_handle of child thread is initialized with parent thread's Fiber handle. Furthermore, second call of `ConvertThreadToFiber()` for the same thread fails. This patch solves this weird situateion. However, maybe we can make more clean code. * thread.c (thread_start_func_2): call `rb_threadptr_root_fiber_setup_by_child()` at thread initialize routine. * vm.c (th_init): call `rb_threadptr_root_fiber_setup_by_parent()`. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@63073 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* mjit.c: merge MJIT infrastructurek0kubun2018-02-041-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | that allows to JIT-compile Ruby methods by generating C code and using C compiler. See the first comment of mjit.c to know what this file does. mjit.c is authored by Vladimir Makarov <vmakarov@redhat.com>. After he invented great method JIT infrastructure for MRI as MJIT, Lars Kanis <lars@greiz-reinsdorf.de> sent the patch to support MinGW in MJIT. In addition to merging it, I ported pthread to Windows native threads. Now this MJIT infrastructure can be compiled on Visual Studio. This commit simplifies mjit.c to decrease code at initial merge. For example, this commit does not provide multiple JIT threads support. We can resurrect them later if we really want them, but I wanted to minimize diff to make it easier to review this patch. `/tmp/_mjitXXX` file is renamed to `/tmp/_ruby_mjitXXX` because non-Ruby developers may not know the name "mjit" and the file name should make sure it's from Ruby and not from some harmful programs. TODO: it may be better to store this to some temporary directory which Ruby is already using by Tempfile, if it's not bad for performance. mjit.h: New. It has `mjit_exec` interface similar to `vm_exec`, which is for triggering MJIT. This drops interface for AOT compared to the original MJIT. Makefile.in: define macros to let MJIT know the path of MJIT header. Probably we can refactor this to reduce the number of macros (TODO). win32/Makefile.sub: ditto. common.mk: compile mjit.o and mjit_compile.o. Unlike original MJIT, this commit separates MJIT infrastructure and JIT compiler code as independent object files. As initial patch is NOT going to have ultra-fast JIT compiler, it's likely to replace JIT compiler, e.g. original MJIT's compiler or some future JIT impelementations which are not public now. inits.c: define MJIT module. This is added because `MJIT.enabled?` was necessary for testing. test/lib/zombie_hunter.rb: skip if `MJIT.enabled?`. Obviously this wouldn't work with current code when JIT is enabled. test/ruby/test_io.rb: skip this too. This would make no sense with MJIT. ruby.c: define MJIT CLI options. As major difference from original MJIT, "-j:l"/"--jit:llvm" are renamed to "--jit-cc" because I want to support not only gcc/clang but also cl.exe (Visual Studio) in the future. But it takes only "--jit-cc=gcc", "--jit-cc=clang" for now. And only long "--jit" options are allowed since some Ruby committers preferred it at Ruby developers Meeting on January, and some of options are renamed. This file also triggers to initialize MJIT thread and variables. eval.c: finalize MJIT worker thread and variables. test/ruby/test_rubyoptions.rb: fix number of CLI options for --jit. thread_pthread.c: change for pthread abstraction in MJIT. Prefix rb_ for functions which are used by other files. thread_win32.c: ditto, for Windows. Those pthread porting is one of major works that YARV-MJIT created, which is my fork of MJIT, in Feature 14235. thread.c: follow rb_ prefix changes vm.c: trigger MJIT call on VM invocation. Also trigger `mjit_mark` to avoid SEGV by race between JIT and GC of ISeq. The improvement was provided by wanabe <s.wanabe@gmail.com>. In JIT compiler I created and am going to add in my next commit, I found that having `mjit_exec` after `vm_loop_start:` is harmful because the JIT-ed function doesn't proceed other ISeqs on RESTORE_REGS of leave insn. Executing non-FINISH frame is unexpected for my JIT compiler and `exception_handler` triggers executions of such ISeqs. So `mjit_exec` here should be executed only when it directly comes from `vm_exec` call. `RubyVM::MJIT` module and `.enabled?` method is added so that we can skip some tests which don't expect JIT threads or compiler file descriptors. vm_insnhelper.h: trigger MJIT on method calls during VM execution. vm_core.h: add fields required for mjit.c. `bp` must be `cfp[6]` because rb_control_frame_struct is likely to be casted to another struct. The last position is the safest place to add the new field. vm_insnhelper.c: save initial value of cfp->ep as cfp->bp. This is an optimization which are done in both MJIT and YARV-MJIT. So this change is added in this commit. Calculating bp from ep is a little heavy work, so bp is kind of cache for it. iseq.c: notify ISeq GC to MJIT. We should know which iseq in MJIT queue is GCed to avoid SEGV. TODO: unload some GCed units in some safe way. gc.c: add hooks so that MJIT can wait GC, and vice versa. Simultaneous JIT and GC executions may cause SEGV and so we should synchronize them. cont.c: save continuation information in MJIT worker. As MJIT shouldn't unload JIT-ed code which is being used, MJIT wants to know full list of saved execution contexts for continuation and detect ISeqs in use. mjit_compile.c: added empty JIT compiler so that you can reuse this commit to build your own JIT compiler. This commit tries to compile ISeqs but all of them are considered as not supported in this commit. So you can't use JIT compiler in this commit yet while we added --jit option now.

* ia64: update ia64-specific code to use execution contexthsbt2018-01-301-3/+3
| | | | | | | | | | | | | | | | | | | | This change follows commit 837fd5e494731d7d44786f29e7d6e8c27029806f in '#ifdef __ia64' branches. Noticed as a build failure by John Paul Adrian Glaubitz: ``` cont.c:502:50: error: 'rb_thread_t {aka struct rb_thread_struct}' has no member named 'machine' size = cont->machine.register_stack_size = th->machine.register_stack_end - th->machine.register_stack_start; ^~ ``` The change is trivial: update 'th->machine' usage to 'th->ec->machine'.

* cleanup hook cleanup code.ko12017-11-161-0/+8
| | | | | | | | | | | | | | | | | | | | * vm_trace.c: before this patch, deleted hooks are remvoed at *the beggining* of hooks (exec_hooks_precheck). This patch cleanup deleted hooks at (1) just after hook is deleted (TracePoint#disable and so on) (2) just after executing hooks (exec_hooks_postcheck) Most of time (1) is enough, but if some threads running hooks, we need to wait cleaning up deleted hooks until threads finish running the hooks. This is why (2) is introduced (and this is why current impl cleanup deleted hooks at the beggining of hooks). * test/lib/tracepointchecker.rb: check also the number of delete waiting hooks. * cont.c (cont_restore_thread): fix VM->trace_running count. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@60782 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

| | | | | | | | | | * cont.c (cont_save_thread): clear only `stack_end`. Clearing tells GC mark function to ignore this macine stack (not allocated yet). `stack_start` will be used by machine stack store/restore phase (on FIBER_USE_NATIVE == 0), so that only `stack_end` is cleared. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@59829 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
