2023-11-23windows-arm64 support (#8995)Pierrick Bouvier
* [win32] fix compilation for windows-arm64 Credits to MSYS2 Ruby package using this patch. * [win32] nm use full options Fix compilation error when using MSYS2 environment. Credits to MSYS2 Ruby package using this patch. * [win32] detect llvm-windres (used for windows-arm64) When adding preprocessor option for llvm-windres (using clang as parameter), it fails. Thus, do not add this. It's needed to be able to compile windows-arm64 version, because MSYS2 toolchain is LLVM based (instead of GCC/binutils). * [win32] pioinfo detection for windows-arm64 This fixes "unexpected ucrtbase.dll" for native windows-arm64 ruby binary. It does not solve issue with x64 version emulated on this platform. Value of pioinfo pointer can be found in ucrtbase.dll at latest adrp/add sequence before return of _isatty function. This works for both release and debug ucrt. Due to the nature of aarch64 ISA (vs x86 or x64), it's needed to disassemble instructions to retrieve offset value, which is a bit more complicated than matching specific string patterns. Details about adrp/add usage can be found in this blog post: https://devblogs.microsoft.com/oldnewthing/20220809-00/?p=106955 For instruction decoding, the Arm documentation was used as a reference.

2023-07-17Remove __bp__ and speed-up bmethod calls (#8060)Alan Wu
Remove rb_control_frame_t::__bp__ and optimize bmethod calls This commit removes the __bp__ field from rb_control_frame_t. It was introduced to help MJIT, but since MJIT was replaced by RJIT, we can use vm_base_ptr() to compute it from the SP of the previous control frame instead. Removing the field avoids needing to set it up when pushing new frames. Simply removing __bp__ would cause crashes since RJIT and YJIT used a slightly different stack layout for bmethod calls than the interpreter. At the moment of the call, the two layouts looked as follows: ┌────────────┐ ┌────────────┐ │ frame_base │ │ frame_base │ ├────────────┤ ├────────────┤ │ ... │ │ ... │ ├────────────┤ ├────────────┤ │ args │ │ args │ ├────────────┤ └────────────┘<─prev_frame_sp │ receiver │ prev_frame_sp─>└────────────┘ RJIT & YJIT interpreter Essentially, vm_base_ptr() needs to compute the address to frame_base given prev_frame_sp in the diagrams. The presence of the receiver created an off-by-one situation. Make the interpreter use the layout the JITs use for iseq-to-iseq bmethod calls. Doing so removes unnecessary argument shifting and vm_exec_core() re-entry from the interpreter, yielding a speed improvement visible through `benchmark/vm_defined_method.yml`: patched: 7578743.1 i/s master: 4796596.3 i/s - 1.58x slower C-to-iseq bmethod calls now store one more VALUE than before, but that should have negligible impact on overall performance. Note that re-entering vm_exec_core() used to be necessary for firing TracePoint events, but that's no longer the case since 9121e57a5f50bc91bae48b3b91edb283bf96cb6b. Closes ruby/ruby#6428
2023-03-16Add thread and ractor counts to bug reportsAlan Wu
This is useful for crash triaging. It also helps to hint extension developers about the misuse of `rb_thread_call_without_gvl()`. Example: $ ./miniruby -e 'Ractor.new{Ractor.receive}; Thread.new{sleep}; Process.kill:SEGV,Process.pid' <snip> -- Threading information --------------------------------------------------- Total ractor count: 2 Ruby thread count for this ractor: 2 Notes: Merged: https://github.com/ruby/ruby/pull/7532

2022-06-03Prevent printing crash report in a loopAlan Wu
In the event that we are crashing due to a corrupt Ruby stack, we might re-enter rb_vm_bugreport() due to failed assertions in rb_backtrace_print_as_bugreport() or SDR(). In these cases we were printing the bug report ad infinitum with unbounded recusion. I seem to run into this every once in a while and the amount of log it prints out is pretty distracting. On CI environments it makes the log output unnecessarily big. Let's fix this. Notes: Merged: https://github.com/ruby/ruby/pull/5731
2022-05-24remove `NON_SCALAR_THREAD_ID` supportKoichi Sasada
`NON_SCALAR_THREAD_ID` shows `pthread_t` is non-scalar (non-pointer) and only s390x is known platform. However, the supporting code is very complex and it is only used for deubg print information. So this patch removes the support of `NON_SCALAR_THREAD_ID` and make the code simple. Notes: Merged: https://github.com/ruby/ruby/pull/5933
2022-04-23introduce struct `rb_native_thread`Koichi Sasada
`rb_thread_t` contained `native_thread_data_t` to represent thread implementation dependent data. This patch separates them and rename it `rb_native_thread` and point it from `rb_thraed_t`. Now, 1 Ruby thread (`rb_thread_t`) has 1 native thread (`rb_native_thread`). Notes: Merged: https://github.com/ruby/ruby/pull/5836

2021-06-02Do not expect ec on rb_vm_bugreportTakashi Kokubun
because a SEGV might happen on an MJIT worker. As you can clearly see from `if (vm && ec) {`, ec is not guaranteed to exist here.

An MJIT worker thread doesn't have ec, and it's required for SDR() and rb_backtrace_print_as_bugreport(). Therefore it must be checked.

2020-09-03Introduce Ractor mechanism for parallel executionKoichi Sasada
This commit introduces Ractor mechanism to run Ruby program in parallel. See doc/ractor.md for more details about Ractor. See ticket [Feature #17100] to see the implementation details and discussions. [Feature #17100] This commit does not complete the implementation. You can find many bugs on using Ractor. Also the specification will be changed so that this feature is experimental. You will see a warning when you make the first Ractor with `Ractor.new`. I hope this feature can help programmers from thread-safety issues. Notes: Merged: https://github.com/ruby/ruby/pull/3365

Since this commit (https://github.com/ruby/ruby/commit/9e1b06e17d27fb4ddf51e9244f205417e9c4dd5c), the VM Debug Level constant is moved from `vm_insnhelper.h` to `vm_core.h`. This PR is a super tiny update to reflect that change so that people won't waste time on searching in a wrong file.

2020-02-22Introduce disposable call-cache.Koichi Sasada
This patch contains several ideas: (1) Disposable inline method cache (IMC) for race-free inline method cache * Making call-cache (CC) as a RVALUE (GC target object) and allocate new CC on cache miss. * This technique allows race-free access from parallel processing elements like RCU. (2) Introduce per-Class method cache (pCMC) * Instead of fixed-size global method cache (GMC), pCMC allows flexible cache size. * Caching CCs reduces CC allocation and allow sharing CC's fast-path between same call-info (CI) call-sites. (3) Invalidate an inline method cache by invalidating corresponding method entries (MEs) * Instead of using class serials, we set "invalidated" flag for method entry itself to represent cache invalidation. * Compare with using class serials, the impact of method modification (add/overwrite/delete) is small. * Updating class serials invalidate all method caches of the class and sub-classes. * Proposed approach only invalidate the method cache of only one ME. See [Feature #16614] for more details. Notes: Merged: https://github.com/ruby/ruby/pull/2888
