#13059: High memory usage during compilation -------------------------------------+------------------------------------- Reporter: domenkozar | Owner: (none) Type: bug | Status: closed Priority: highest | Milestone: 8.2.1 Component: Compiler | Version: 8.0.2-rc2 Resolution: fixed | Keywords: Generics Operating System: Unknown/Multiple | Architecture: x86_64 Type of failure: Compile-time | (amd64) performance bug | Test Case: Blocked By: | Blocking: Related Tickets: #5642, #11068 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Changes (by RyanGlScott): * status: new => closed * resolution: => fixed Comment: I honestly don't think there's a consistent rule that you shouldn't inline any default method implementations. Rather, this is a very particular case where inlining a chain of `GHC.Generics`-related instance methods together leads to high memory usage, which feels more like a bug than anything. My vote is to close this and pursue the discussion in #5642 and #11068, where this behavior has been observed before. Feel free to reopen if you disagree. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13059#comment:23 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
