#8971: Native Code Generator for 7.8 is not as optimized as 7.6.3... -------------------------------------+------------------------------------- Reporter: GordonBGood | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler (NCG) | Version: 7.8.1-rc2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Runtime | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by GordonBGood): This bug has not been assigned to GHC Milestone 8.2 so I don't suppose any action will be taken on it. I just checked with GHC 8.0.1 and the problem is still there, with the NCG produced code for these type of tight loops running about four times slower with x86 code than for x64 code. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8971#comment:27 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
