; This tests that a hot callee gets the (higher) inlinehint-threshold even
|
|
; without inline hints and gets inlined because the cost is less than
|
|
; inlinehint-threshold. A cold callee with identical body does not get inlined
|
|
; because cost exceeds the inline-threshold. This test is relevant only when the
|
|
; old pass manager is used.
