#13085: -fregs-graph is ignored but this is undocumented -------------------------------------+------------------------------------- Reporter: jberryman | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Documentation | 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: #13033, #7192 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Changes (by bgamari): * related: => #13033, #7192 Comment: Indeed `-fregs-graph` has been a bit of a state of disarray since the merge of the new code generator, at which point it regressed in performance to the point of being worse than the linear allocator in some cases (#7192). At this point the flag was disabled. tjakway has been interested in dusting it off so I tried to re-enable the flag for 8.0.2, but unfortunately this prompted #13033 which forced me to revert the change. Regardless, I hadn't noticed that `-fregs-graph` lacked documentation; thanks for pointing this out. This should be fixed for 8.2.1, when `-fregs-graph` should be finally enabled. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13085#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
