Thanks for the pull request, and welcome! The Rust team is excited to review your changes, and you should hear from @Amanieu (or someone else) some time within the next two weeks. |
Tested in the simulator and on the device I had lying around, a 1st generation iPad Mini (which isn't Aarch64, but shows that the `sysctlbyname` calls still work even there, even if they return false). `sysctlbyname` _should_ be safe to use without causing rejections from the app store, as its usage is documented in: https://developer.apple.com/documentation/kernel/1387446-sysctlbyname/determining_instruction_set_characteristics Also, the standard library will use these soon anyhow, so this shouldn't affect the situation: rust-lang/rust#129019

This was originally added in #1516.
I have tested this in the simulator and on the device I had lying around, a 1st generation iPad Mini (which isn't Aarch64, but shows that the
sysctlbynamecalls still work even there, even if they return false).sysctlbynameshould be safe to use without causing rejections from the app store, as its usage is documented in:https://developer.apple.com/documentation/kernel/1387446-sysctlbyname/determining_instruction_set_characteristics
Also, the standard library will use
sysctlsoon anyhow, see rust-lang/rust#129019, so if the standard library starts getting rejected by Apple, it won't be entirelystdarch's fault.A few more references:
