The invocations in `clang/test/Driver/cuda-omp-unsupported-debug-options.cu` don't pass `-emit-llvm` but `-###`. ``` > cat /dev/null | ./bin/clang -### -x cuda - -nogpulib -nogpuinc -c && echo $? ``` should error with recent CUDA installations because of `sm_35`. https://github.com/llvm/llvm-project/pull/84008 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
