One known user of that API is lang/ponyc, where I contributed a workaround: https://github.com/ponylang/ponyc/commit/81ba52c90cb87a049be8052754a8b031de= 59593d There should be versions of this function for FreeBSD/aarch64 (by reading ID_AA64ISAR0_EL1/ID_AA64PFR0_EL1/ID_AA64ISAR1_EL1 in userspace) and armv\d|powerpc(64)?
