; Test behavior when inlining policy grows size out of control.
|
|
; In all cases, the end result is the same: mandatory inlinings must happen.
|
|
; However, when we discover we 'trip' over the artificially-low size increase
|
|
; factor, we penalize the 'bad' decision.
|
|
; REQUIRES: have_tf_api
