This reverts an earlier attempt (adb0d8ddceb143749c519d14b8b31b481071da77 and 50e5411e4247421fd606f0a206682fcdf0303ae3) to support these expansions, which was limited to type arguments and which subverted the purpose of SubstTemplateTypeParmType. This propagates the ArgumentPackSubstitutionIndex along with the AssociatedConstraint, so that the pack expansion works, without needing any new transforms or otherwise any changes to the template instantiation process. This keeps the tests from the reverted commits, and adds a few more showing the new solution also works for NTTPs. Fixes https://github.com/llvm/llvm-project/issues/131798
//===----------------------------------------------------------------------===// // Clang Tools repository //===----------------------------------------------------------------------===// Welcome to the repository of extra Clang Tools. This repository holds tools that are developed as part of the LLVM compiler infrastructure project and the Clang frontend. These tools are kept in a separate "extra" repository to allow lighter weight checkouts of the core Clang codebase. All discussion regarding Clang, Clang-based tools, and code in this repository should be held using the standard Clang forum: https://discourse.llvm.org/c/clang Code review for this tree should take place on the standard Clang patch and commit lists: http://lists.llvm.org/mailman/listinfo/cfe-commits If you find a bug in these tools, please file it in the LLVM bug tracker: https://github.com/llvm/llvm-project/issues/
