Use the target triple from the C++ toolchain instead of deriving it from values in the Apple configuration fragment.#768
Closed
Conversation
…rom values in the Apple configuration fragment. When using `--host_cpu=darwin_x86_64` on an ARM (Apple Silicon) host, the value returned by the Apple configuration fragment is wrong, and we end up compiling Swift for `arm64`. Since the C++ toolchain already has the correct triple verbatim as we want it in the `target_gnu_system_name` field, just use that, and add some generally useful utilities for manipulating the triples and their components. Note to open-source rules maintainers: This change requires/assumes that your C++ toolchain configuration returns a complete target triple that includes minimum OS version and target environment; for example, `x86_64-apple-ios13.0-simulator`.

Either one is fine. I'm not near a computer in the next few days to rebase this so I guess just take yours? |
