#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: closed Priority: normal | Milestone: Component: Compiler | Version: 8.0.1 Resolution: invalid | 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 alexbiehl): Ok, thanks for the explanation! But one last question: Why is GHC 8.0.1 and HEAD even in perf flavour not able to inline the length function on the vector? {{{#!hs ... Just a -> case length $fVectorVectora a of { I# y -> case y of { ... }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12916#comment:10 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
