Tested in 6.6.1 and today's 6.7 (which claims to be version 6.7.20070418),
{{{newtype FastBool = FastBool Int#}}}
doesn't work. However this is not documented in the unboxed-types
documentation in the User's Guide that lists similar restrictions
http://www.haskell.org/ghc/docs/latest/html/users_guide/primitives.html
Similarly (maybe), in phantom type arguments, even in GADTs where kind
inference could be at work
{{{data Boo a where Boo :: Int# - Boo Int#}}}
doesn't work.
I tried {{{newtype ( FastBool :: # ) = ...}}} , and {{{data Boo ( a :: # )
where...}}} , which just confused GHC.
Is there a reason that coercions of unlifted types shouldn't work, or is
it just unimplemented? (inspired by looking at GHC's
compiler/utils/FastTypes.lhs and thinking that using newtypes instead of
type synonyms in places like that would improve type-safety)

There are a bunch of places where the compiler assumes newtypes are lifted but that could be fixed. The newtype would have all the limitations of unlifted types though. You still couldn't use it in polymorphic functions or anything (which might be somewhat surprising to users of your code). Probably a better use of time would be to make SpecConstr turn enumeration types into `Int#`s, thus eliminating the need for FastBool altogether. As a side note, isn't FastBool kind of broken by design? You can't really do anything useful with it other than turning it back into a plain old Bool. `and#`/`or#` don't make sense as they must be strict in both of their arguments (which probably isn't what you want). The GADT example can't really work as you can't forall over unboxed tyvars. You can't write: `unBoo :: forall (a::#) . Boo a - a` as `a` could have a completely different representation depending on how it was instantiated. You could probably make it so `unBoo :: Boo Int# - Int#` would work but why not just write `BooInt = BooInt Int#` at that point. -Brian -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/1311 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler___ Glasgow-haskell-bugs mailing list Glasgow-haskell-bugs@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs

Comment:
Actually, the page was correct previously. The standard benchmarking
function 'nfib', called indeed notorious in the nofib suite, is
{{{
nfib n = if n = 1 then 1 else nfib (n-1) + nfib (n-2) + 1
}}}
It does not compute the Fibonacci numbers! It computes the number of
reductions required in a program that would compute the fibonacci
numbers. Subtle difference. But this is the standard historical
benchmark.

You must expose parallelism to the compiler in one of the following two ways./pdiv class=sect2 lang=endiv class=titlepagedivdivh3 class=titlea name=id3181681/a7.15.1. Running Concurrent Haskell programs in parallel/h3/div/div/divpThe first possibility is to use concurrent threads to structure your program, and make sure that you spread computation amongst the threads. The runtime will schedule the running Haskell threads among the available OS threads, running as many in parallel as you specified with the code class=option-N/code RTS option./p/divdiv class=sect2 lang=endiv class=titlepagedivdivh3 class=titlea name=id3181704/a7.15.2. Annotating pure code for parallelism/h3/div/div/divpThe simplest mechanism for extracting parallelism from pure code is to use the code class=literalpar/code combinator, which is closely related to (and often used with) code class=literalseq/code. Both of these are available from a href=http://haskell.org/ghc/docs/6.6/html/libraries/base/Control- Parallel.html target=_topcode class=literalControl.Parallel/code/a:/ppre class=programlistinginfixr 0 `par` infixr 1 `seq` par :: a -gt; b -gt; b seq :: a -gt; b -gt; b/prepThe expression code class=literal(x `par` y)/code span class=emphasisemsparks/em/span the evaluation of code class=literalx/code (to weak head normal form) and returns code class=literaly/code.

RE: Documentation bug? {Numeric,GHC.Float}.floatToDigits: requires anon-negative argument
Good point. I've fixed GHC's online documentation as you suggest. For
the H98 report I'll put it in the bug list.

RE: GHC Source Build documentation BUG
while trying to adapt the local bootstrap-from-scratch script that allows us to install a somewhat customized GHC onto our systems starting from nothing but an installed GCC 2.95, I noticed a bug in the documentation accompanying the GHC 6.2 release. On http://www.haskell.org/ghc/download_ghc_62.html there is a note stating The source distribution needs an installed GHC 4.08.X, 5.X or 6.X to build. As 4.08.2 is relatively easily bootstrapped using a C compiler, that is the base we start off, and thus I figured I could just jump from 4.08.2 to 6.2. Unfortunately, the compilation itself then states: :94: #error GHC = 5.00 is required for bootstrapping GHC Annoying, that. Especially given that I *checked* if I could jump from 4.08.2 to 6.2. Sorry about that. We lost the ability to bootstrap from 4.08 in 6.2, and didn't update the docs. However, as Don pointed out, 6.2 can be bootstrapped from C sources rather more easily than previous versions, so there's no need to start from 4.08. Follow the detailed instructions in the Building Guide, and you should be fine.

RE: Documentation bug
The online documentation of the concurrent package seems a bit dated. I just found out (by trial and error) that the functions putCVar and getCVar has changed names to readCVar and writerCVar. The name change is great but it would be nice if the documentation could reflect this. Thanks; fixed.
