I would:
 - Remove some of the noalias and noundef if they do not alter the test. local_unnamed_addr can probably be removed.
 - presision -> precision
 - Make the run line something like `RUN: llc --mtriple=aarch64-unknown-linux-gnu < %s | FileCheck %s`, mostly for consistency with other tests.
 - Run update_llc_test_checks.py on the file, to show the output. As you say it doesn't matter much what it is, but it can be good to check it looks OK.
