Support running the test suite from Darwin host on a non-Darwin target #150806
Description
The LLDB test suite supports running remotely. We have at least tow bots that run Linux and Windows as the host OS and target a remote Linux machine. On Darwin platforms, we rely on this functionality to test remote Darwin devices.
However, we don't seem to support targeting a non-Darwin device from a Darwin host. We use the host platform to pick the builder. Windows and Linux both use the default builder, so there it goes unnoticed. But on Darwin we have a custom one , which for example uses xcrun to find the SDK, which doesn't apply when targeting a non-Darwin device. That's the first issue I ran into, and I worked around it by using lldbplatformutil.getPlatform() instead. There might be more. The purpose of this issue is to track making this configuration work.
