#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 RyanGlScott): I'm having difficulty reproducing this with a build of GHC HEAD at commit ddc271e8ed6c5ec5e83dd50c6c5e77955a0e90ac. In fact, the Core I get looks just about identical to the one that GHC 8.0.1 produces (with `$wempResult`). FWIW, this is using `io-streams-1.3.5.0` and `vector-0.11.0.0`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12916#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
