Hey, I'm currently looking at building a portable version of the standard library (for targeting microcontrollers, kernel dev, etc).
The easiest way to cross compile Swift at the moment (that I can find) is to get swiftc to generate LLVM IR (-emit-ir), and use clang to build and cross compile. This obviously leaves the problem that there won't be a standard lib to link against on the target. I figured that the best way to accomplish this would probably be to implement whatever stubs are necessary for the target (e.g. all the libc calls). I am struggling to find the best way to build the standard library though. I've got a copy of the stdlib files, have run gyb over all of the templates, and am attempting to get swiftc to compile everything and output a giant IR file. I was wondering if there was an easier way to go about building a custom libswiftcore? It would obviously be great to be able to use Swift in this way without an OS, as it would open up a lot of opportunities for use of the language (embedded development, etc). Thanks, Andy
