| |
| This script is used to continually test the back-deployment use case of libc++ and libc++abi on MacOS. |
| |
| --libcxx-root Full path to the root of the libc++ repository to test. |
| --libcxxabi-root Full path to the root of the libc++abi repository to test. |
| --std Version of the C++ Standard to run the tests under (c++03, c++11, etc..). |
| --arch Architecture to build the tests for (32, 64). |
| --deployment-target The deployment target to run the tests for. This should be a version number of MacOS (e.g. 10.12). All MacOS versions until and including 10.9 are supported. |
| --sdk-version The version of the SDK to test with. This should be a version number of MacOS (e.g. 10.12). We'll link against the libc++ dylib in that SDK, but we'll run against the one on the given deployment target. |
| [--lit-args] Additional arguments to pass to lit (optional). If there are multiple arguments, quote them to pass them as a single argument to this script. |
| [--no-cleanup] Do not cleanup the temporary directory that was used for testing at the end. This can be useful to debug failures. Make sure to clean up manually after. |
| [-h, --help] Print this help. |
