#12916: GHC 8.0.1 vs GHC HEAD (8.1.20161202) doesn't do inlining and unboxing very well -------------------------------------+------------------------------------- Reporter: alexbiehl | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.1 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 rwbarton): Right, `quickest` is basically designed to see whether the stage2 compiler works at all, as fast as possible. So it doesn't bother optimizing the libraries (and you will get a slow stage2 compiler that generates slow code). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12916#comment:8 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
