So other modules need only import GHC.Base. This doesn't change the fact that these other modules are all compiled before GHC.Err, so they are all part of the module loop that starts with GHC.Base and finishes with GHC.Err. But it does reduce the occurrence of those SOURCE imports. ] [Tuple tycons have parens around their names simonpj@microsoft**20071220171812 The name of the pair TyCon, in the Typeable instance, should be "(,)" not ",".

Also the algorithm failed to count readers as required by Haskell 98 (#629). Now it's done using a hash table (provided by the RTS). Furthermore I avoided the extra fstat() for every open file by passing the dev_t and ino_t into lockFile. This and the improvements to the locking algorithm result in a healthy 20% or so performance increase for opening/closing files (see openFile008 test). ] [Only overwrite GHC/Prim.hs and GHC/Primopwrappers.hs if they change Simon Marlow **20071120102042 This avoids make doing unnecessary work after 'setup makefile'. ] [fix comment Simon Marlow **20071116091227] [Fix ` characters in elem's haddock docs Ian Lynagh **20071110173052] [Filter out GHC.Prim also for the Haddock step David Waern **20071109000806 Please merge to the GHC 6.8.2 branch ] [Add module of special magic GHC desugaring helper functions Simon Marlow **20071102160054 Currently containing only one such helper: (>>>) for arrow desugaring ] [add Control.Category to the nhc98 build Malcolm.Wallace@cs.york.ac.uk**20071030120459] [fix nhc98 build: need a qualified Prelude import Malcolm.Wallace@cs.york.ac.uk**20071030120410] [Fix performance regression: re-instate -funbox-strict-fields Simon Marlow **20071029150730 Yikes! While investigating the increase in code size with GHC 6.8 relative to 6.6, I noticed that in the transition to Cabal for the libraries we lost -funbox-strict-fields, which is more or less depended on by the IO library for performance. I'm astonished that we didn't notice this earlier! To reduce the chances of this happening again, I put -funbox-strict-fields in the OPTIONS_GHC pragma of the modules that need it. {-# UNPACK #-} pragmas would be better, though. ] [FIX BUILD: Haddock 1.x fails to parse (Prelude..)
