-; The goal of this test is checking if LastCallToStaticBonus is applied
-; correctly while deciding inline deferral. For the test code below, when
-; inliner evaluates the callsite of bar->baz, it checks if inlining of bar->baz
-; prevents ininling of foo->bar, even when foo->bar inlining is more beneficial
-; than bar->baz inlining. As LastCallToStaticBonus has a massive value, and
-; both baz and bar has only one caller, the cost of foo->bar inlining and
-; bar->baz inlining should be non-trivial for inliner to compute that bar->baz
-; inlining can actaully prevent foo->bar inlining. To make the cost of these
-; callsites big enough, loop unrolling pass with very high threshold is used to
-; preprocess the test.
