#3064: Very long compile times with type functions -------------------------------------+------------------------------------- Reporter: simonpj | Owner: Type: bug | Status: closed Priority: low | Milestone: 7.12.1 Component: Compiler (Type | Version: 6.10.1 checker) | Keywords: Resolution: fixed | Architecture: Operating System: Unknown/Multiple | Unknown/Multiple Type of failure: Compile-time | Test Case: performance bug | perf/compiler/T3064 Blocked By: | Blocking: Related Tickets: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by goldfire): Good points in comment:21. I'm especially swayed by the ease with which this regression can be avoided, whereas previous problems were not. I do think, once a decision is made regarding 7.10 vs 7.12, a release note should be added. And, if possible, an error message that includes a note whenever the strictly-decreasing-superclass criterion bites would also be great. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/3064#comment:22 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
