#14490: TTG Snags -------------------------------------+------------------------------------- Reporter: alanz | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.3 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: #14482 | Differential Rev(s): Wiki Page: | ImplementingTreesThatGrow | -------------------------------------+------------------------------------- Comment (by alanz): I made a very quick attempt yesterday at removing the Data instances completely, but they are in fact used, I introduced them for the dump AST stuff. I want to first get an idea of what the major performance driver is, before focusing exclusively on instances. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14490#comment:20 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
