[ruby-core:121207] [Ruby master Bug#21164] Performance Regression using --jit

From: "purbug28 (puni ru) via ruby-core" <ruby-core@...>
Date: 2025-02-28 14:43:06 UTC
List: ruby-core #121207
Issue #21164 has been reported by purbug28 (puni ru).

----------------------------------------
Bug #21164: Performance Regression using --jit
https://bugs.ruby-lang.org/issues/21164

* Author: purbug28 (puni ru)
* Status: Open
* ruby -v: ruby 3.4.2 (2025-02-15 revision d2930f8e7a) +PRISM [x86_64-linux]
* Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN
----------------------------------------
Ruby 3.4.2 --jit runs slower than no JIT, while Ruby 3.3.7 --jit runs faster.
```ruby
# frozen_string_literal: true
n = 200000
c = Array.new(n + 1, 0)
(1..n).each do |i|
  a = []
  m = 100
  (1..m).each do
    a << i
    c[i] += 1
    a << i / m
    c[i % m] += 1
  end
end
puts c.sum
```
