But if it turns out that my suggestion has a poor user experience, I don't insist it only be done from the frontend -- I am mostly trying to avoid duplicating the logic for checking for a C compilation unit. Everything eventually funnels through the frontend, so it seems most reasonable to catch it there instead of from the driver. https://github.com/llvm/llvm-project/pull/200318 _______________________________________________ cfe-commits mailing list [email protected] https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
