Since the Apple devkits are all presumably returned to Apple at this point, it doesn't make sense to continue to build for the earlier a12 model, we should just build for the M1 explicitly. LLVM supports `-mcpu=apple-m1` since LLVM 13.0.0-rc1 [0]. Clang 13 (ships with Xcode 13) understands this, so it's a safe bet that this can be used with the C compiler that is generating this code as well. [0] llvm/llvm-project@a8a3a43

I think you're mixing up vanilla LLVM with Apple Clang. Xcode up to 13.2.1 ships Apple Clang 13 which is based on upstream LLVM 12 (ref: https://en.wikipedia.org/wiki/Xcode#Xcode_11.x_-_13.x_(since_SwiftUI_framework)_2), but it's true that XCode 13.0+ (with at least version string |
