AaronBallman wrote:This RUN line would make more sense in a file with a .cpp extension; the .c extension means we already imply `-x c` and so that can be a bit confusing. What should the frontend behavior be btw? e.g., ``` // RUN: %clang_cc1 -fsycl -x c %s ``` I presume you also want to reject this despite it not happening from the driver? Or do you want to allow cc1 invocations to accept C code and only prevent driver executions? https://github.com/llvm/llvm-project/pull/200318 _______________________________________________ cfe-commits mailing list [email protected] https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
