#10613: Mechanism for checking that we only enter single-entry thunks once -------------------------------------+------------------------------------- Reporter: bgamari | Owner: Type: feature request | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.10.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: Other | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by simonmar):
Right, that would be sufficient to detect thunks that are wrongly marked single-entry. But we also want to learn about thunks that are not marked single-entry, but should be.
Do you expect to learn much by doing that? We know the analysis is inaccurate, and I expect you'll just find a lot of thunks that are used a long way from the definition site. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10613#comment:10 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
