Sorry for my late reply. https://github.com/llvm/llvm-project/pull/68131 IIUC `clang -fdebug-types-section -g -gpubnames` does not emit `.debug_names`. #68131 will implement the support (accidentally committed, reverted in f320065aeb379d8f9d2780a687768742f8b18eb2). `git cherry-pick -n 9bbd2bf654634cd95dd0be7948ec8402c3c76e1e` has merge conflicts, so it seems difficult for me to play with the example...
