#15286: "Can't use Natural in base" when compiling GHC.Natural with -O0 -------------------------------------+------------------------------------- Reporter: alpmestan | Owner: (none) Type: bug | Status: patch Priority: normal | Milestone: Component: libraries/base | Version: 8.5 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Building GHC | Unknown/Multiple failed | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D4880 Wiki Page: | -------------------------------------+------------------------------------- Comment (by simonpj): Compiling `Num` with `-O0` will kill numeric performance for every single Haskell program -- it's not acceptable. Does anyone understand what the actual problem is here? Why does it only happen with Hadrian? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15286#comment:6 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
