#82727 was filed because this extension is used by topling-zip: https://github.com/topling/topling-zip/blob/4c57da837bf1a1612a1524ddf8d258a69f1c3874/src/terark/zbs/blob_store.hpp#L56-L68 I decided to implement this feature after I read the post by @rockeet :https://zhuanlan.zhihu.com/p/683534962 (in Chinese). TBH I don't think this feature is useful as modern compilers should be smart enough to optimize out redundant vtable lookups. cc @rockeet Are you willing to propose an RFC in https://discourse.llvm.org/ to demonstrate its real-world usefulness in ToplingDB? https://github.com/llvm/llvm-project/pull/135649 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
