@compnerd Okay, I figured out my original problem. So, in https://github.com/llvm/llvm-project/pull/95234 the reason I stopped seeing the issue was because I moved to using `DEFAULT_TARGET_ONLY` mode. The `test_target_architecture` version uses this `simple.cc` which then fails due to the `printf`. I think it should be fine to build this if the user has a compatible `clang`, so maybe I should revive that patch?
