2021-10-20Cleanup diff against upstream. Add commentsAlan Wu
I did a `git diff --stat` against upstream and looked at all the files that are outside of YJIT to come up with these minor changes.
2021-10-20Remove the scraperAaron Patterson
Now that we're using the jit function entry point, we don't need the scraper. Thank you for your service, scraper. ❤️
2021-10-20Remove some MicroJIT vestigesAaron Patterson
Just happened to run across this, so lets fix them
2021-10-20YJIT: lazy polymorphic getinstancevariableAlan Wu
Lazily compile out a chain of checks for different known classes and whether `self` embeds its ivars or not. * Remove trailing whitespaces * Get proper addresss in Capstone disassembly * Lowercase address in Capstone disassembly Capstone uses lowercase for jump targets in generated listings. Let's match it. * Use the same successor in getivar guard chains Cuts down on duplication * Address reviews * Fix copypasta error * Add a comment

Notes: Merged: https://github.com/ruby/ruby/pull/4633
2021-08-21Allow tracing of optimized methodsJeremy Evans
This updates the trace instructions to directly dispatch to opt_send_without_block. So this should cause no slowdown in non-trace mode. To enable the tracing of the optimized methods, RUBY_EVENT_C_CALL and RUBY_EVENT_C_RETURN are added as events to the specialized instructions.

2021-05-31Decompose the captured_cc code for investigationTakashi Kokubun
I'm investigating SEGVs like https://github.com/ruby/ruby/runs/2715166621?check_suite_focus=true. Because a lot of things are going on on this line, it's hard to identify the cause, especially because we can't get the core file of the failures. Therefore I intentionally increased the number of lines for investigation.
2021-03-10Remove DEFINED_IVAR2 from enumJohn Hawthorn

2021-01-11Avoid re-entering opt_invokebuiltin_delegate_leaveTakashi Kokubun
on interruption. The cancellation code was originally written for leave insn, but re-entering opt_invokebuiltin_delegate_leave insn on a cancellation is not safe, because a builtin function is executed twice.
2021-01-04Fix broken JIT of getinlinecacheTakashi Kokubun
e7fc353f04 reverted vm_ic_hit_p's signature change made in 53babf35ef, which broke JIT compilation of getinlinecache. To make sure it doesn't happen again, I separated vm_inlined_ic_hit_p to make the intention clear.
2021-01-04Avoid using inconsistent coding styleTakashi Kokubun
Other `_mjit_compile_*.erb` files don't use goto. These files'd better be consistent for readability.
2021-01-05enable constant cache on ractorsKoichi Sasada
constant cache `IC` is accessed by non-atomic manner and there are thread-safety issues, so Ruby 3.0 disables to use const cache on non-main ractors. This patch enables it by introducing `imemo_constcache` and allocates it by every re-fill of const cache like `imemo_callcache`. [Bug #17510] Now `IC` only has one entry `IC::entry` and it points to `iseq_inline_constant_cache_entry`, managed by T_IMEMO object. `IC` is atomic data structure so `rb_mjit_before_vm_ic_update()` and `rb_mjit_after_vm_ic_update()` is not needed.

2020-10-17sync RClass::ext::iv_index_tblKoichi Sasada
iv_index_tbl manages instance variable indexes (ID -> index). This data structure should be synchronized with other ractors so introduce some VM locks. This patch also introduced atomic ivar cache used by set/getinlinecache instructions. To make updating ivar cache (IVC), we changed iv_index_tbl data structure to manage (ID -> entry) and an entry points serial and index. IVC points to this entry so that cache update becomes atomically. Notes: Merged: https://github.com/ruby/ruby/pull/3662
2020-10-14sync generic_ivtblKoichi Sasada
generic_ivtbl is a process global table to maintain instance variables for non T_OBJECT/T_CLASS/... objects. So we need to protect them for multi-Ractor exection.

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
