#10565: GHC 7.10.2 RC: the impossible happened on hPDB-examples-1.2.0.2 ---------------------------------+-------------------------------------- Reporter: snoyberg | Owner: bgamari Type: bug | Status: closed Priority: normal | Milestone: 7.10.2 Component: Compiler | Version: 7.10.2-rc1 Resolution: wontfix | Keywords: Operating System: Linux | Architecture: x86_64 (amd64) Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | ---------------------------------+-------------------------------------- Comment (by MichalGajda): It would be indeed nice, if GHC could factorize pattern matching to be logarithmic in all cases. That would greatly improve performance in case of integer range lookup, and so for much of the token comparison codes. Of course clever people already use hashes and atoms, but ability to program at the highest possible level will always bring numerous fans to Haskell. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10565#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
