| ## Show that lit reports the path of tools found via use_llvm_tool. |
| ## Additionally show that use_llvm_tool uses in order of preference: |
| ## 1) The path specified in an environment variable, |
| ## 2) The LLVM tools build directory, |
| ## 3) The PATH, if requested. |
| |
| # RUN: %{lit} %{inputs}/use-llvm-tool 2>&1 | \ |
| # RUN: FileCheck %s -DDIR=%p |
| |
| ## The exact breakdown of cases is: |
| ## Case | Env | Build Dir | PATH | |
| ## 1 | / | X | N/S | <- Can be found via env |
| ## 2 | X | / | N/S | <- Can be found via build dir if env specified |
| ## 3 | N/S | / | N/S | <- Can be found via build dir |
| ## 4 | N/S | X | / | <- Can be found via PATH, if requested |
| ## 5 | N/S | X | N/S | <- Cannot be found via PATH, if not requested |
| ## 6 | / | / | / | <- Env is preferred over build, PATH |
| ## 7 | N/S | / | / | <- Build dir is preferred over PATH |
| ## 8 | X | X | X | <- Say nothing if cannot be found if not required |
| ## 9 | N/S | override | N/S | <- Use specified search directory, instead of default directory |
| ## 10 | N/S | override | / | <- Use PATH if not in search directory |
| |
| ## Check the exact path reported for the first case, but don't bother for the |
| ## others. |
