#13059: High memory usage during compilation -------------------------------------+------------------------------------- Reporter: domenkozar | Owner: Type: bug | Status: new Priority: highest | Milestone: 8.2.1 Component: Compiler | Version: 8.0.2-rc2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: x86_64 Type of failure: Compile-time | (amd64) performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Changes (by RyanGlScott): * cc: simonpj (added) Comment: The question now is: how was GHC generating default instance methods prior to 54b887b5abf6ee723c6ac6aaa2d2f4c14cf74060? Perhaps there's a way we could go back to the way the code was generated while preserving the typechecking benefits of 54b887b5abf6ee723c6ac6aaa2d2f4c14cf74060. Simon, do you recall how this worked prior to 54b887b5abf6ee723c6ac6aaa2d2f4c14cf74060? Unfortunately, `-ddump-deriv` didn't show the generated code for default instance methods prior to 54b887b5abf6ee723c6ac6aaa2d2f4c14cf74060, so it's hard for me to figure out what happened before. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13059#comment:18 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
