#10260: last uses too much space with optimizations disabled -------------------------------------+------------------------------------- Reporter: rwbarton | Owner: nomeata Type: bug | Status: patch Priority: normal | Milestone: Component: Core Libraries | Version: 7.10.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Runtime | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Revisions: Phab:D847 -------------------------------------+------------------------------------- Comment (by simonpj): Well ''all'' eta-expansion risks what you say. If the user wants hat kind of control s/he can use INLINE/INLINEABLE. The eta expansion doesn't happen for the template that is inlined; only in the RHS that is compiled. Which is good. So I do think we should eta-expand here. The only reason not to is described in the comment. I think. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10260#comment:13 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
