2024-06-05Don't add `+YJIT` to `RUBY_DESCRIPTION` until it's actually enabled (#10920)Jean byroot Boussier
If you start Ruby with `--yjit-disable`, the `+YJIT` shouldn't be added until `RubyVM::YJIT.enable` is actually called. Otherwise it's confusing in crash reports etc. Co-authored-by: Jean Boussier <jean.boussier@gmail.com>

2023-10-20YJIT: On test_bug_19316, only check the resultAlan Wu
Because the `&` call checks for interrupts, the test was accidentally timing dependent. Stop checking for exits. [Bug #19921] Reported-by: Vít Ondruch <vondruch@redhat.com> Reported-by: Mamoru Tasaka <mtasaka@fedoraproject.org>
2023-10-19YJIT: Make test_yjit.rb faster with --yjit-stats=quietAlan Wu
The for-human stats summaries are not relevant for the children `test_yjit.rb` spawns. Avoid compiling and running the printing code. On a -O0 dev build this halves the time for `test_yjit.rb` on my machine.
2023-10-19YJIT: Print exit reasons on failure in test_yjit.rbAlan Wu
For <https://bugs.ruby-lang.org/issues/19921>, I suspect the test is failing due to a timing related interrupt, which on paper could happen with slow-enough GC runs. In any case, it's helpful for debugging to have more information when tests fail. Co-authored-by: Takashi Kokubun <takashikkbn@gmail.com>

2023-10-18YJIT: Use RbConfig.ruby instead of EnvUtil.rubybin (#8689)Takashi Kokubun
Some people encounter an issue that test_yjit uses the installed Ruby instead of the currently-running Ruby. It's fixed when they remove the installed Ruby. However, test_yjit should run the currently-running Ruby for testing YJIT in subprocesses. EnvUtil is unfortunately used outside tests as well, so for compatibility reasons, this commit only changes the argument given to EnvUtil.invoke_ruby to always use RbConfig.ruby.

2023-06-06YJIT: Avoid identity-based known-class guards for IO objects (#7911)Alan Wu
`IO#reopen` is very special in that it is able to change the class and singleton class of IO instances. In its presence, it is not correct to assume that IO instances has a stable class/singleton class and guard by comparing identity. Notes: Merged-By: maximecb <maximecb@ruby-lang.org>
2023-04-20YJIT: invokesuper: Remove cme mid matching checkJohn Hawthorn
This check was introduced to match an assertion in the C YJIT when this was originally introduced. I don't believe it's necessary for correctness of the generated code.

2023-03-28YJIT: Add `--yjit-pause` and `RubyVM::YJIT.resume` (#7609)Maxime Chevalier-Boisvert
* YJIT: Add --yjit-pause and RubyVM::YJIT.resume This allows booting YJIT in a suspended state. We chose to add a new command line option as opposed to simply allowing YJIT.resume to work without any command line option because it allows for combining with YJIT tuning command line options. It also simpifies implementation.

2023-03-21YJIT: Fix deadlock in tests due to pipe capacityAlan Wu
Previously, when there is enough stats that the child process fills up the pipe capacity, the child process would block, with the parent process waiting forever as no one is reading to clear up the pipe. The test timed out in these situations. Use a separate thread in the parent to read from the pipe to unblock the child in these situation. EnvUtil also does this for handling stdout and stderr. I had the test suite deadlock on a Linux VM. Notes: Merged: https://github.com/ruby/ruby/pull/7578 Merged-By: XrXr

2023-02-27YJIT: Detect and reject `send(:alias_for_send, :foo)`Alan Wu
Previously, YJIT failed to put the stack into the correct shape when `BasicObject#send` calls an alias method for the send method itself. This can manifest as strange `NoMethodError`s in the final non-send receiver, as [seen][1] with the kt-paperclip gem. I also found a case where it makes YJIT fail the stack size assertion while compiling `leave`. YJIT's `BasicObject#__send__` implementation already rejects sends to `send`, but didn't detect sends to aliases of `send`. Adjust the detection and reject these cases.

2023-02-24YJIT: Generate Block::entry_exit with block entry PCAlan Wu
Previously, when Block::entry_exit is requested from any instruction that is not the first one in the block, we generated the exit with an incorrect PC. We should always be using the PC for the entry of the block for Block::entry_exit. It was a simple typo. The bug was [introduced][1] while we were refactoring to use the current backend. Later, we had a chance to spot this issue while [preparing][2] to enable unused variable warnings, but didn't spot the issue. Fixes [Bug #19463] [1]: 27fcab995e6dde19deb91dc6e291bdb72100af68 [2]: 31461c7e0eab4963ccc8649ea8ebf27979132c0c Notes: Merged: https://github.com/ruby/ruby/pull/7374 Merged-By: XrXr

2023-02-16YJIT: jit_prepare_routine_call() for String#+@ missingAlan Wu
We saw SEGVs due to this when running with StackProf, which needs a correct PC for RUBY_INTERNAL_EVENT_NEWOBJ, the same event used for ObjectSpace allocation tracing. [Bug #19444] Notes: Merged: https://github.com/ruby/ruby/pull/7328

2023-01-10YJIT: Save PC and SP before calling leaf builtins (#7090)Alan Wu
Previously, we did not update `cfp->sp` before calling the C function of ISEQs marked with `Primitive.attr! "inline"` (leaf builtins). This caused the GC to miss temporary values on the stack in case the function allocates and triggers a GC run. Right now, there is only a few leaf builtins in numeric.rb on Integer methods such as `Integer#~`. Since these methods only allocate when operating on big numbers, we missed this issue. Fix by saving PC and SP before calling the functions -- our usual protocol for calling C functions that may allocate on the GC heap. [Bug #19316] Notes: Merged-By: maximecb <maximecb@ruby-lang.org>
2023-01-03YJIT: Fix `yield` into block with >=30 locals on ARMAlan Wu
It's a register spill issue. Fix by moving the Qnil fill snippet to after registers are released. [Bug #19299] Notes: Merged: https://github.com/ruby/ruby/pull/7059
2022-12-15YJIT: Fix `obj.send(:call)`Alan Wu
All the method call types need to handle argument shifting in case they're called by `.send`, and we weren't handling that in `OPTIMIZED_METHOD_TYPE_CALL`. Lack of shifting caused the stack size assertion in gen_leave() to fail. Discovered by Rails CI: https://buildkite.com/rails/rails/builds/91705#018516c4-f8f8-469e-bc2d-ddeb25ca8317/1920-2067 Diagnosed with help from `@eileencodes` and `@k0kubun`.

2022-11-25YJIT: Run test-all tests without requiring RUN_OPTSAlan Wu
Most tests in test_yjit.rb use a sub process, so we can run them even when the parent process is not running with YJIT. Run them so simply running `make check` tests YJIT a bit. [Misc #19149] Notes: Merged: https://github.com/ruby/ruby/pull/6814
2022-11-17YJIT: Make the code GC test stablerTakashi Kokubun
The first `add_pages` call shouldn't hit Code GC yet; otherwise `compiles` returns false. With the increased code size in runtime_stats itself, it sometimes hits Code GC too early, at least in arm64 that has a large code size.
