 ; CHECK-NEXT:    sub sp, sp, #32
-; CHECK-NEXT:    .cfi_def_cfa_offset 32
 ; CHECK-NEXT:    str x30, [sp, #16] // 8-byte Folded Spill
+; CHECK-NEXT:    .cfi_def_cfa_offset 32
----------------
`.cfi_def_cfa_offset 32` move like this seems unnecessary. It degrades precision without reducing the number of CFI instructions for sync.
