From 64bb812be5f8b691365f3b28503de952abc16999 Mon Sep 17 00:00:00 2001 From: simonm Date: Tue, 9 Sep 1997 14:22:33 +0000 Subject: [PATCH] [project @ 1997-09-09 14:22:33 by simonm] remove redundant RELEASE (users_guide/2-06-notes is used instead) --- ghc/RELEASE | 129 ----------------------------------------------------------- 1 file changed, 129 deletions(-) delete mode 100644 ghc/RELEASE diff --git a/ghc/RELEASE b/ghc/RELEASE deleted file mode 100644 index 4a11ba1..0000000 --- a/ghc/RELEASE +++ /dev/null @@ -1,129 +0,0 @@ -This is the release notes for GHC-2.04, describing what's new since the -previous release: - -GHC 2.04 is a minor upgrade of GHC 2.02 (and the bugfix release, -2.03), representing work done through May '97. This new release -adds the following: - -* Data constructors can now have polymorphic fields, and ordinary - functions can have polymorphic arguments. Details on - - http://www.cse.ogi.edu/~simonpj/quantification.html - - Existential types coming, but not done yet. - -* Pattern guards implemented, see - - http://www.cse.ogi.edu/~simonpj/guards.html - -* Compiler can now compile itself. - -* INLINE pragmas honoured (caveat: not yet - working on instance-decl methods) - -* Simplifier improvements and better inlining gives - better code; not sure how *much* better. - -* -dshow-rn-stats print out amusing statistics about what - the renamer does. - -* When compiling without -O, the renamer (the pass responsible for - slurping in interface file and making sure everything is in scope - etc.) is now more careful about what it will bring in (especially - data constructors and instance declarations). The upshot of this - change is that a lot of the (unnecessary) work this pass did in - 2.02/2.03 is now avoided. - - -fno-prune-tydecls and -fno-prune-instdecls switch off these - renamer optimisations. You can try the effect with the renamer - statistics. War stories welcome. - -* The Heroic Efforts of \tr{Andr\'e Santos } have - been included, AIX/RS6000 is now a supported \tr{ghc} - platform! Bug reports concerning this port to (as always) - glasgow-haskell-bugs@dcs.gla.ac.uk - -* A lot of the bugs that were present in versions 2.02/2.03 - have been fixed (thanks to everyone that reported bugs!). - A list of the reported problems with 2.02/2.03 can be found at - - http://www.dcs.gla.ac.uk/fp/software/ghc/ghc-bugs.html - - No doubt entries for 2.04 will be added here as well :-) - -* This release is available in source format only. To build it you'll - need to have either a copy of GHC~0.29 or GHC~2.02/3 installed. - For people either doing porting work or work on a (supported) - platform for which there is no GHC binary bundles available, the - necessary intermediate files are also available (.hc and .hi files). - - Consult the installation guide for more information on how - to build or bootstrap. The guide is included in the distribution - (in the fptools/docs directory), and an on-line version of the - document can be found at - - http://www.dcs.gla.ac.uk/fp/software/ghc/ghc-doc/install-guide.html - - -In addition to the above, we've made the following minor changes to -the GHC libraries/our implementation of the Haskell standard prelude: - -* `isPrefixOf' and `isSuffixOf' has been added to `List' -* The empty type `Void' is now exported from the prelude. -* `GlaExts' exports the `Lift' data type: - - data Lift a = Lift a - - you might need it someday... - -* The `Foreign' interface now also exports the representations - for `Word' and `Addr' - -* The low-level file handle interface in the POSIX system - library has been reworked a bit, most notably is the renaming of - `Channel' to `Fd' and the introduction of operations for converting - to and from `Handle' and `Fd' values. The changes are: - - --Renamed functions (old name in square brackets) - openFd :: FilePath - -> OpenMode - -> Maybe FileMode - -> OpenFileFlags - -> IO Fd - -- [openChannel] - fdSeek :: Fd -> SeekMode -> FileOffset -> IO FileOffset - --[seekChannel] - fdRead :: Fd -> ByteCount -> IO (String, ByteCount) - --[readChannel] - fdWrite :: Fd -> String -> IO ByteCount - --[writeChannel] - fdClose :: Fd -> IO () - --[closeChannel] - setFdOption :: Fd -> FdOption -> Bool -> IO () - --[setChannelOption] - queryFdOption :: Fd -> FdOption -> IO Bool - --[queryChannelOption] - dup :: Fd -> IO Fd - --[dupChannel] - dupTo :: Fd -> Fd -> IO () - --[dupChannelTo] - - data FdOption = AppendOnWrite | CloseOnExec | NonBlockingRead - --[ChannelOption] - getFdStatus :: Fd -> IO FileStatus - --[getChannelStatus] - - -- New data structure collecting together misc flags passed to openFd - data OpenFileFlags = - OpenFileFlags { - append :: Bool, - exclusive :: Bool, - noctty :: Bool, - nonBlock :: Bool, - trunc :: Bool - } - - --New ops for converting between Fd and Handle: - fdToHandle :: Fd -> IO Handle - handleToFd :: Handle -> IO Fd - intToFd :: Int -> Fd -- use with care. -- 1.7.10.4
