;; Test for different function processing orders affecting inlining in sample profile loader.

;; There is an SCC _Z5funcAi -> _Z8funcLeafi -> _Z5funcAi in the program.

|
;; With -use-profile-top-down-order=0, the top-down processing order of

;; that SCC is (_Z8funcLeafi, _Z5funcAi), which is determinined based on

|
|
;; from profile are considered, thus the order becomes (_Z5funcAi, _Z8funcLeafi)
|
