ARM macs apparently have some kind of specific handling in place for this when a process is running with x86_64 compatibility, but it’s not publicly documented anywhere that I can see.

XNU has this oddity: https://github.com/apple-oss-distributions/xnu/blob/f6217f89...
Redacted from open source XNU, but exists in the closed source version
Is it actually redacted, or just a leftover stub from a feature implemented in silicon instead of software? Isn't the x86 memory order compatibility done at hardware level?
