#5113: Huge performance regression of 7.0.2, 7.0.3 and HEAD over 7.0.1 and 6.12 (MonoLocalBinds) -------------------------------------+------------------------------------- Reporter: | Owner: daniel.is.fischer | Status: closed Type: bug | Milestone: Priority: normal | Version: 7.0.3 Component: Compiler | Keywords: Resolution: fixed | performance, MonoLocalBinds Operating System: Linux | Architecture: x86 Type of failure: Runtime | Test Case: performance bug | perf/should_run/T5113 Blocked By: | Blocking: Related Tickets: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by bgamari): This is odd as the good and bad cases have identical output from `-ddump- rules` and I can clearly see the rule in the Core output in both cases. For some reason it just never fires in the bad case. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/5113#comment:10 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
