ZJIT: Remove GuardShape from known-frozen object with same shape by 39bytes · Pull Request #15863 · ruby/ruby

39bytes · 2026-01-13T19:07:49Z

When we have LoadField with a Shape return type, we can fold it similar to the object case.
GuardBitEquals can be removed when the argument is Const and the values are equal.

The behaviors for loading instances variables from frozen/dynamic objects are already covered in existing tests so no new tests were added.

looks great --thank you!
