The scenario that brought this up was `constinit` globals still generating constructors that just call `__cxa_atexit`; this behavior was regarded as prima facie "odd", since it invokes quite a lot of mechanism just to register statically-known destructors. With an approach like this, such constructors wouldn't need to be generated; the little state machine in the module constructor function would take it as granted that such "constructors" executed successfully. We'd probably need some additional mechanism in Clang's data structures to keep track of this though. https://github.com/llvm/llvm-project/pull/115788 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
