"macabi" is not an "ABI" in the same sense as e.g. "gnueabihf" · Issue #133331 · rust-lang/rust (original) (raw)
I know it has the literal characters "abi" in it but it's not an "ABI" in the sense of "gnueabihf", the HF and SF targets use actually-different calling conventions. It should probably have been a target_env
.
Same story with the Apple "sim" targets.
