Sources and binaries -are freely available by anonymous FTP and on the World-Wide Web; -details below. - -Haskell is "the" standard lazy functional programming language; the -current language version is 1.3, agreed in May, 1996. The Haskell -Report is online at - - http://haskell.cs.yale.edu/1.4/haskell-report.html - -GHC 2.02 is a beta-quality release - some highlights: - - * It is reliable. - It has been extensively tested against a large suite of Haskell 1.2 - programs, but not so extensively tested against Haskell 1.4 programs - because we don't have a comprehensive set (Donations of Haskell 1.4 - programs to our test suite are most welcome). - - * It should generate good code. - All the optimisations that GHC 0.29 used to do are back in, with - the exception of specialisation. It ought to be the case that - GHC 2.02 outperforms GHC 0.29, because it has a much better - handle on cross-module inlining, but there's a good chance that - there are performance "holes" lurking. We have yet to make - a systematic comparison. (Please send us programs where 2.02 - does noticeably worse than 0.29.) - - * It is more expensive than it should be. - GHC 2.02 has received even less attention to its own performance. - At present it eats more space and time than GHC 0.29, especially - for very small programs. We're working on this. - - * A couple of Haskell 1.4 features are incompletely supported, - notably polymorphic strictness annotations, and Unicode. - -If you want to use Haskell 1.4, this is a good moment to switch. If -you don't need the Haskell 1.4 extensions, then stay with GHC 0.29. -If you want to hack on GHC itself, then 2.02 is definitely for you. -The release notes comment further on this point. - -GHC 2.02 is substantially changed from 2.01. Changes worth noting -include: - - * The whole front end, which deals with the module system, has - been rewritten. The interface file format has changed. - - * GHC 2.02 comes complete with Green Card, a C foreign language - interface for GHC. Green card is a pre-processor that - scans Haskell source files for Green Card directives, which - it expands into tons of "ccall" boilerplate that marshalls - your arguments to and from C. - - * GHC 2.02 is available for Win32 platforms. From now on, Win32 - (Windows NT and Windows 95) will be a fully supported platform - for GHC. - - * GHC 2.02 supports full cross module inlining. Unlike 0.29 and - its predecessors, inlining can happen even if the inlined body - mentions a function or type that is not itself exported. This is - one place Haskell 1.4's new module system really pays off. - - * Like 2.01, GHC 2.02 aborts a compilation if it decides that - nothing that the module imports *and acually uses* has changed. - This decision is now taken by the compiler itself, rather than - by a Perl script (as in 2.01) which sometimes got it wrong. - - * The ghc/lib libraries are much more systematically organised. - - * There's a completely new "make" system. This will mainly affect people - who want the source distribution, who will hopefully find it much, much, - easier than grappling with the old Jmakefiles. Even for binary - installation, the procedure is a little simpler, though. - -Please see the release notes for a complete discussion of What's New. - -To run this release, you need a machine with 16+MB memory (more if -building from sources), GNU C (`gcc'), and `perl'. We have seen GHC -2.01 work on these platforms: alpha-dec-osf2, hppa1.1-hp-hpux9, -sparc-sun-{sunos4,solaris2}, mips-sgi-irix5, and -i386-unknown-{linux,solaris2,freebsd,cygwin32}. Similar platforms -should work with minimal hacking effort. The installer's guide give a -complete run-down of what-ports-work. - -Binaries are distributed in `bundles', e.g. a "profiling bundle" or a -"concurrency bundle" for your platform. Just grab the ones you need. - -Once you have the distribution, please follow the pointers in the -README file to find all of the documentation about this release.
