; This tests that a callsite which is determined to be hot based on the caller's
|
|
; entry count and the callsite block frequency gets the hot-callsite-threshold.
|
|
; Another callsite with the same callee that is not hot does not get inlined
|
|
; because cost exceeds the inline-threshold. inlinthint-threshold is set to 0
|
|
; to ensure callee's hotness is not used to boost the threshold.
