-; This tests that the function count of a function gets properly scaled after
-; inlining a call chain leading to the function.
-; Function a calls c with count 200 (C1)
-; Function c calls e with count 250 (C2)
-; Entry count of e is 500 (C3)
-; Entry count of c is 500 (C4)
-; Function b calls c with count 300 (C5)
-; c->e inlining does not happen since the cost exceeds threshold.
-; c then inlined into a.
-; e now gets inlined into a (through c) since the branch condition in e is now
-; known and hence the cost gets reduced.
-; Estimated count of a->e callsite = C2 * (C1 / C4)
-; Estimated count of a->e callsite = 250 * (200 / 500) = 100
-; Remaining count of e = C3 - 100 = 500 - 100 = 400
-; Remaining count of c = C4 - C1 - C5 = 500 - 200 - 300 = 0
