#15996: Add Unlifted List type to base -------------------------------------+------------------------------------- Reporter: chessai | Owner: (none) Type: feature request | Status: new Priority: normal | Milestone: 8.6.3 Component: libraries/base | Version: 8.6.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by carter): Hey Daniel: do you have any examples where the timing measurements would be improved by these changes to qsem? Or where unlifted list would be faster ? I agree that they might reduce indirections, but having concrete programs which benefit measurably from the change helps ground things. Also let’s us measure the impact -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15996#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
