Hello,
According to the release notes there is a new package that now contains the
module Data.Array.Diff.
According to Ian's commit this package is called diffarray.
This package does not seem to be available on Hackage.
Could someone upload it?
Rene.

Hello,
Where is the documentation on how pinning works in the GHC garbage collector
(from a GHC users point of view).
I have copied the following code from array/IO.hs and am thinking that it is
assuming that the array is pinned? What triggers the pinning?
On a second note.
Why is the type
I suggest that the code in GHC.Arr be changed from
error Error in array index
to
error Error in array index ++ show b ++ show i
so that the bounds and offending index is shown. This is easy to do as the
information is already available, and would in most cases be of great help
to the user
One idea that occurred to us recently is this: GHCi could provide a
simplified version of the cost-centre-stack machinery *all the time*,

This still doesn't explain to me why
C:\Haskell\devmain +RTS -xc

Hello,
I tried to compile HAppS using the latest GHC snapshot (in compiles fine
with 6.41).
I for example get the error

Perhaps. That's what I'd like feedback about. What do others think?

Hello *,
I noticed a five percent speed up by making local definitions global.
Maybe the global defintions are monomorphic, and the local defintions
are polymorphic. You could evaluate the types of the global types

BTW. The -fno-recomp option has a very unintuitive name, at least for
me. When I see -fno-recomp, my brain thinks no recompilation,
meaning no unneccesary recompilation, which is what --make does by
default. Using
Is there anyway to turn off that ghci runs in threaded mode on windows?
fps 0.8 (and software that uses fps) triggers trac error #806.
This means that I cannot run such things interactively :-(

The flags under section
4.17.26. Compiler debugging options
seem to be out of date. They seem to be wrong for both 6.42 and 6.6
For example --ddump-cmm is not listed, but works.
But --ddump-absC is listed, and gives the error unknown flag.
I can't get -ddump-stix to work either.

Hello,
What do I need to install for the regex library support on MINGW?
It looks like the regex library needs the posix library, and in my MINGW /
MSYS installation I don't find one
(and neither does configure).

Hello Ian,
Is it on purpose that the lastest windows build does not include
cabal-install?
Since the September builds I don't see any logs for the mingw build?

There may be a heuristic that would help more programs to go through... but
I prefer asking the programmer to make the desired behaviour explicit.

How can the user make this explicit?
With the

Hello,
I am attempting some genetic programming in Haskell.
Rather than defining my own data type for programs and writing my own
interpreter, I want to use the template haskell expression data types and
evaluate them with the rts's byte code interpreter. This gives me a nice
fast interpreter

Yes, by default we don't build or supply the GHC package with profiling,
because of the extra bloat it would add to the downloads and the time
taken to build it.
Why is a program so large when I use the GHC module?
What are the plans for http://hackage.haskell.org/trac/ghc/ticket/5623 which
seems to be still open?
Quoting form the ticket ...
Just to spam a little more, it seems that the HEAD happily duplicates all
computations on unboxed types. It even duplicates x+x in this example:
foo :: Float - Float
24 matches
