I'd prefer not to mess with the way DeferredDecls works for decls that aren't impossible to emit, if possible. I don't think "odr-used" is a useful concept here; I think it's possible for an decl to be odr-used even if there isn't a mangling. Alternatively, we could just invent a mangling here, like we did for #117845. https://github.com/llvm/llvm-project/pull/124572 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
