Issue #19298 has been updated by hsbt (Hiroshi SHIBATA). Thanks @k0kubun and @vo.x. I created the backport request at https://github.com/ruby/ruby/pull/7061 ---------------------------------------- Bug #19298: `lib/mjit/instruction.rb` was reintroduced by merge mistake https://bugs.ruby-lang.org/issues/19298#change-100984 * Author: vo.x (Vit Ondruch) * Status: Closed * Priority: Normal * ruby -v: ruby 3.2.0 (2022-12-25 revision a528908271) [x86_64-linux] * Backport: 2.7: DONTNEED, 3.0: DONTNEED, 3.1: DONTNEED, 3.2: REQUIRED ---------------------------------------- It seems that `lib/mjit/instruction.rb` should not be shipped anymore since commit:git|bb4cbd0803c3297ad036008adc7a01159ce44e1e, but it was re-introduced into the repository by merge mistake commit:git|f6620037ba1477d2c337d7b511f094d6d0fbb69c. Actually, it was probably never part of the repository, but was part of the tarball, but it seems it should not be. -- https://bugs.ruby-lang.org/
