## 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.
