1 ;; This test makes sure a static var is not selected as a callee target (it will
2 ;; have a different GUID). Similarly, ensure that a callee GUID annotated from a
3 ;; sample pgo profile that matches a global variable GUID (either due to code
4 ;; changes or a hash collision), does not get considered for importing. Either
5 ;; of these can crash compilation.
