| 4 | // Simple compilation case: |
| 5 | // RUN: %clang -### -c %s 2>&1 \ |
| 6 | // Compile device-side to PTX assembly and make sure we use it on the host side. |
| 7 | // RUN: | FileCheck -check-prefix CUDA-D1 \ |
| 8 | // Then compile host side and incorporate device code. |
| 9 | // RUN: -check-prefix CUDA-H -check-prefix CUDA-H-I1 \ |
| 10 | // Make sure we don't link anything. |
| 11 | // RUN: -check-prefix CUDA-NL %s |

| 18 | // RUN: -check-prefix CUDA-H -check-prefix CUDA-H-I1 \ |
| 19 | // Then link things. |
| 20 | // RUN: -check-prefix CUDA-L %s |
