[swift-dev] How to run the tests out-of-tree?

[Karl]

Hi

So I’ve been working on cross-compiling for ARM, and it seems pretty good - only a bit of refactoring of the build script really needed. It’s a popular request, the lack of which is hindering lots of people and businesses who would like to experiment with swift on their ARM-based devices.

The thing that’s really missing before I can propose merging these changes is running the in-tree tests (swift/tests/ folder) to validate the products. I basically want to copy that folder in to a package and run it on the target device, but I’m not really sure how to do that with lit. I’ve built the unit test binaries (the ones which statically link against the runtime), and those obviously are easy enough to package and script for out-of-tree use.

Can anybody help with this?

Thanks

Karl
