#13739: Very slow linking of profiled executables -------------------------------------+------------------------------------- Reporter: duog | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.2.1-rc2 Resolution: | Keywords: Operating System: Linux | Architecture: x86_64 Type of failure: Compile-time | (amd64) performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by duog): I have attached a script and my output that exhibits a large slowdown in linking a trivial profiled executable. It times linking a file Main.hs with {{{main = return ()}}} with ghc-8.0.2 and ghc-8.2.0.2017.0522. It shows that the linking times irrespective of -fwhole-archive-hs-libs has slowed considerably, and that -fwhole-archive-hs-libs slows down linking by 4-5x on both ghc versions. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13739#comment:8 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
