#9927: Should simplifier try more iterations? -------------------------------------+------------------------------------- Reporter: goldfire | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Build System | Version: 7.11 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by simonpj): You mean this {{{ WARNING: file compiler/simplCore/SimplCore.hs, line 600 Simplifier bailing out after 4 iterations [2187, 49, 3, 1] }}} The numbers are the numbers of transformations carried out in each iteration. If you see `[blah, 1,1,1]` it's clue that maybe some transformation isn't making progress and is happening repeatedly, or generally that the cascade of transformations isn't working well. Increasing the iteration count can show this up even more vividly. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9927#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
