#13426: compile-time memory-usage regression for DynFlags between GHC 8.0 and GHC 8.2 -------------------------------------+------------------------------------- Reporter: hvr | Owner: (none) Type: bug | Status: new Priority: high | Milestone: 8.2.1 Component: Compiler | Version: 8.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by rwbarton): I have similar numbers from after the join points commit (Feb 1) and they do not show this large regression. So my educated guess is that the new Typeable stuff is responsible. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13426#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
