#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 agree on Plan C. But I am currently concerned that the major slowdown is not just from the instances. I understand bgamari is going to revert the TTG commits, and there is now a detailed timing flag (https://phabricator.haskell.org/rGHC2da7813b771edcb3efb1b067b986d10f5de4beaf) which we will be able to use to compare the compilation time for the before and after versions. This should at least give us an idea of where the major impacts are coming from, in terms of modules. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14490#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
