$(basename ${0}) [-h|--help] --monorepo-root <MONOREPO-ROOT> --std <STD> --arch <ARCHITECTURE> [--lit-args <ARGS...>]
This script is used to continually test libc++ and libc++abi trunk on MacOS.
--monorepo-root Full path to the root of the LLVM monorepo. Both libc++ and libc++abi from the monorepo are used.
--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).
--libcxx-exceptions Whether to enable exceptions when building libc++ and running the libc++ tests. libc++abi is always built with support for exceptions because other libraries in the runtime depend on it (like libobjc). This must be ON or OFF.
[--cmake-args] Additional arguments to pass to CMake (both the libc++ and the libc++abi configuration). If there are multiple arguments, quote them to paass them as a single argument to this script.
[--lit-args] Additional arguments to pass to lit. 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.
