; Some code that will result in actual AA queries, including inside of a loop.
; FIXME: Sadly, none of these queries managed to use either the domtree or
; loopinfo that basic-aa cache. But nor does any other test in LLVM. It would
; be good to enhance this to actually use these other analyses to make this
; a more thorough test.
