So the problem here is actually that something has gone horribly wrong when configuring compiler- rt. You'll notice in the clang commands that it is building in this directory: clang_rt.builtins_armv7_10.4.dir What that means is it is building the clang_rt.10.4 archive which provides back ported library functions to OS X 10.4. Obviously 10.4 didn't support armv7 as an architecture, something has gone really wrong here. If you're on the latest swift it is probably a regression caused by 53f48f8. You need to email swift-dev to get support from Dmitri Gribenko and Vedant Kumar. Source: I wrote most of the compiler-rt builtin build system for Darwin.
