-A binary-only from-working-sources no-guarantees snapshot of the
-Glasgow Haskell compiler (GHC) for Linux x86 machines is now available
-by FTP from ftp.dcs.glasgow.ac.uk, in
-pub/haskell/glasgow/ghc-0.25-linux.tar.gz.
-
-This release is the first, long-awaited "registerized" GHC for Linux,
-which produces code of reasonable size and speed. We use our normal
-technique of "stealing registers" with GCC's
-global-variables-in-registers facility. We "steal" six of the x86's
-eight general-purpose registers, including the C stack-pointer (%esp),
-which we use for the heap pointer (Hp).
-
-To use this GHC, you need a special version of GCC, which is also
-provided in the distribution (under "gcc-linux-to-linux"). Whatever
-you do, please do *not* report any "bugs" in this GCC to bug-gcc --
-report them to *me* instead.
-
-One special thing you must watch out for: If GCC "crashes" with a
-message about spilling registers, it is *not* a GCC problem. It means
-you must get GHC to "back off" in its register "stealing". First try
-a -monly-4-regs flag, then -monly-3-regs, and as a last resort,
--monly-2-regs. As far as we know, all Haskell code goes through GHC
-with a -monly-2-regs flag (but it produces substantially worse code
-with that flag).
-
-Profiling is not provided in this release.
-
-Please report any bugs to glasgow-haskell-bugs@dcs.glasgow.ac.uk.

-=== INSTALLATION NOTES ==============================================
-
-Unpack the distribution.
-
-Move "gcc-linux-to-linux" and "ghc-0.25-linux" wherever you like.
-
-Alter the "gcc" script to point to wherever you've put
-"gcc-linux-to-linux", and put the "gcc" script wherever you wish in
-your PATH.
-
-Make a link to ghc-0.25-linux/ghc/driver/ghc, so that "ghc" will be in
-your PATH.
-
-Change *all* hardwired paths in ghc/driver/ghc and in
-ghc/utils/hscpp/hscpp to point to where things are on your system.
-Notably: where "perl" is (first line of each script), where $TopPwd is
-(ghc script), where your gcc cpp is (hscpp script).
-
-GHC should then work. Try "ghc -v" on something simple, to make sure
-it compiles and links a program correctly.
