[libcxx] Add a script to run CI on older MacOS versions
This script can be used by CI systems to test things like availability markup and binary compatibility on older MacOS versions. This is still a bit rough on the edges, for example we don't test libc++abi yet. llvm-svn: 350752

|
||||
|
||||
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 10.7 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.
