|
|
|
|
This script is used to continually test the back-deployment use case of libc++ and libc++abi on MacOS.
|
|
|
|
Specifically, this script runs the libc++ test suite against the just-built headers and linking against the just-built dylib, but it runs the tests against the dylibs for the given deployment target.
|
|
|
|
--monorepo-root Full path to the root of the LLVM monorepo. Both libc++ and libc++abi headers from the monorepo are used.
|
|
--std Version of the C++ Standard to run the tests under (c++03, c++11, etc..).
|
|
--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.
|
|
[--libcxx-roots] The path to previous libc++/libc++abi dylibs to use for back-deployment testing. Those are normally downloaded automatically, but if specified, this option will override the directory used. The directory should have the same layout as the roots downloaded automatically.
|
|
[--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.
