#6084: Add stg_ap_pnnv and related call patterns ---------------------------------+------------------------------------------ Reporter: SimonMeier | Owner: simonmar Type: feature request | Status: infoneeded Priority: normal | Milestone: 7.8.1 Component: Runtime System | Version: 7.4.1 Keywords: | Os: Unknown/Multiple Architecture: Unknown/Multiple | Failure: None/Unknown Difficulty: Unknown | Testcase: Blockedby: | Blocking: Related: | ---------------------------------+------------------------------------------ Comment(by simonpj): Wouldn't adding new call patterns ''also'' be a good idea? The "short- cut" idea simply catches the case where the call is (dynamically) saturated; it doesn't obviate the desirability of having various slow-call patterns. The two ideas seem orthogonal to me.
