-; This tests incremental updates to caller's BFI as a callee gets inlined.
-; In bottom-up inlining, first c->e inlining is considered and fails because
-; e's size exceeds the threshold of 50. Then a->c inlining is considered and it
-; succeeds. a's BFI is updated incrementally. As c's blocks get pruned, the 
-; block with label cond_false is removed and since the remanining code is
-; straight-line a single block gets cloned into a. This block should get the
-; maximum block frequency among the original blocks in c. If it gets the
-; frequency of the block with label cond_true in @c, its frequency will be
-; 1/10th of function a's entry block frequency, resulting in a callsite count of
-; 2 (since a's entry count is 20) which means that a->e callsite will be
-; considered cold and not inlined.
