<!--LLVM PR SUMMARY COMMENT--> @llvm/pr-subscribers-clang Author: None (Sirraide) <details> <summary>Changes</summary> In the discussion around #<!-- -->116792, @<!-- -->rjmccall mentioned that ARCMigrate has been obsoleted and that we could go ahead and remove it from Clang, so this patch does just that. I searched for every mention of ‘ARCMT’/‘ARCMigrate’/‘ObjCRewrite’ and removed everything that seemed related to what I was able to find. I also had to touch a bunch of bazel and gn build scripts as part of this, neither of which I’m familiar with so it’s possible that I missed something there. --- Patch is 1.49 MiB, truncated to 20.00 KiB below, full version: https://github.com/llvm/llvm-project/pull/119269.diff 383 Files Affected: -
