12:42 AM Revision 36809a8d (git): ZJIT: Add fail-fast assert for non-register {cpush,cpop}_pair
- There is no splitting for these so let's add a assert to try and catch
misuse. VRegs are not necessarily registers in the end, so this is best
effort. In those situations they'll get a less proximate panic message. - 12:42 AM Revision f7e73ba3 (git): ZJIT: A64: Avoid gaps in the stack when preserving registers for calls

left an 8-byte gap. Use STP to store a pair at a time instead.

- Is this behavior in Ruby 4.0.1 expected?
```ruby
Data.define(:a, :b).new(1 => 1, a: 2)
#=> #<data a=2, b=1>
Data.define(:a, :b).new(1 => 1, b: 2)

https://github.com/ruby/ruby/pull/15910/ -
- Another related issue:
```ruby
Data.define(:a, :b).new(a: 0, "a" => 1)
```
This creates an instance of `Data` with `b` not initialized, `#<data a=1, b=nil>`. -
- The code below shows `Data::define.new` treats symbol and string keys equivalently:
``` ruby
C = Data.define(:a, :b)
C.new(a: 1, b: 1)

C.new('a' => 1, 'b' => 1)

```

- Objects on the Ruby stack can be GC movable and there is corresponding
code in rb_execution_context_update to update references for moved objects. -
- Since we automatically preserve registers across calls, it's never
necessary to manually and imprecisely do it with `C{Push,Pop}All`.
Delete them to remove the maintenance burden and reduce confusion. -
- Better than nothing!

- Continually locking a mutex `m` can lead to starvation if all other threads are on the waitq of `m`.
Let `T` be the thread that keeps on acquiring mutex `m` in a loop.
Iteration 1:

2) All other threads at... -

- I think yielding Symbols are nicer, returning a plain Integer feels too low level IMO and people might misuse that e.g. `DT_UNKNOWN` is 0 on some platforms.
It's also more verbose and less clear (due to unclear C naming) for the Ruby cal... -

- This patch fixes a problem where `binding.irb` (= force_activate('irb'))
fails under `bundle exec` when the Gemfile does not contain `irb` and
does contain a gem which is (1) not installed in GEM_HOME (2) sourced
using `path:`/`git:`.

- The previous example code was too complex and includes extra logics
that's not relevant to its main usage: `bind`.
