I'm pretty certain it's a bug in the layout of static data constructors.
Here is the assembly code for the static closure for `(Vec 1.0 2.0 3.0
4.0)` (at least I think so). Notice that we're only allocating 4 bytes
per (unboxed) float, whereas we should be allocating 8. Over to you,
Simon.

Reload is somewhat easier, since it is likely that the previous context still makes sense. The problem with this ticket is deciding exactly ''what'' to implement. If someone could have a go at specifying something, that would be a good starting point. The context consists of two sets of modules `(as,bs)` where `as` are the `*M` modules and `bs` are the non-`*` modules. Specify a way to decide what `(as,bs)` should be after a load/add, given the previous `(as,bs)`. -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/1360#comment:3 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 (by simonpj):
OK, so here's what I've seen so far. In `ghc-log.bz2` I see
* That there is a Core Lint failure in the stage 2 build, for file
`RnTypes.lhs`.
* Stage 2 is built with `-O2`
* The Core Lint failure is in the result of `SpecConstr`
* In the specialisation of a join point in `mk_hs_op_ty`.
There is something odd going on, because there are duplicate
specialisations for this join point:
{{{
$j_X6vX [Once*! Nothing] :: GHC.Base.Bool
- GHC.Base.Bool
- IOEnv.IOEnv
(TcRnTypes.Env TcRnTypes.TcGblEnv
TcRnTypes.TcLclEnv)
(HsTypes.HsType Name.Name)
[Arity 2
Str: DmdType SL
RULES: SC:$j_X6vX0 [0] forall {} $j_X6vX GHC.Base.False GHC.Base.True
= $s$j_s6Qh
SC:$j_X6vX1 [0] forall {} $j_X6vX GHC.Base.True GHC.Base.False
= $s$j_s6Qi
SC:$j_X6vX2 [0] forall {} $j_X6vX GHC.Base.False
GHC.Base.False = $s$j_s6Qj
SC:$j_X6vX0 [0] forall {} $j_X6vX GHC.Base.False GHC.Base.True
= $s$j_s6PF
SC:$j_X6vX1 [0] forall {} $j_X6vX GHC.Base.True GHC.Base.False
= $s$j_s6PG
SC:$j_X6vX2 [0] forall {} $j_X6vX GHC.Base.False
GHC.Base.False = $s$j_s6PH]
}}}
There should be three specialisations but there are six. The Core Lint
failure is inside a couple of the specialised functions `$s$j_s6PF` for
example.
I have tried to reproduce this odd specialisation behaviour in 6.8.1 and
the HEAD (by compiling `RnTypes` with `-O2`, but both generate three
specialisations (and no Lint failure) as they should.
So let's see if anyone can reproduce this with 6.8.1 or the HEAD. It's
entirely possible that it's fixed already, but it'd be more reassuring to
track it down and thereby be certain.

Hello again,
I deleted the ghc-6.8.1 source, unpacked a clean copy, and created
build.mk:

I reproduced the error, but this time, even with core-lint enabled, didn't
get the same dump as I did from 20070827. The panic message was merely
what I obtained without the core-lint message enabled, as I posted

Comment (by igloo):
Replying to [comment:9 guest]:
However I don't really know what to do with (-) and [].
I think they (and (,,,)) should be left unqualified.
But I'm confused about the list constructor. Prelude.[] should work but
I've noticed a wierd GHC behaviour (version 6.6 sorry) when using the
constructor qualified. Is there a reason for which GHC fails parsing the
following declarations?
{{{
f = undefined :: Prelude.[] Prelude.Int
g = undefined :: GHC.Base.[] Prelude.Int

You aren't allowed to qualify [], - or (,,,) according to the Haskell 98
report.

Comment (by guest):
@simonpj
I'll work in a patch, thanks for your replies.
@igloo
I don't think it will break anyhting, actually it will protect
Data.Typeable from breaking if a user mixes the predefined basic types
with custom ones (strange, I know, but possible anyway). So I think I'll
use Prelude in my patch since it's implementation-independent.
However I don't really know what to do with (-) and [].
For arrows, I think I'll use conditional compilation. GHC.Prim.(-) in
the case of GHC and I'll find out where's defined in hugs (maybe it's
treated specially and not really defined anywhere)
But I'm confused about the list constructor. Prelude.[] should work but
I've noticed a wierd GHC behaviour (version 6.6 sorry) when using the
constructor qualified. Is there a reason for which GHC fails parsing the
following declarations?
{{{
f = undefined :: Prelude.[] Prelude.Int
g = undefined :: GHC.Base.[] Prelude.Int
}}}
The errors I get are:
{{{

I believe gcc is entitled to make this optimisation, because arithmetic in C is only defined within the bounds of the types, and that includes type conversions. Unfortunately the `-fwrapv` option doesn't apply to type conversions, apparently. I don't see an easy fix (but suggestions are welcome). We use unsigned types everywhere in our back end, only converting to signed types in order to perform signed operations. This strategy apparently relies on undefined C behaviour.

Simon, you could try setting your `build.mk` to quickest, and add `GhcStage3HcOpts = -O2`, then try building a stage 3 compiler, my hunch is that this should reproduce it. Excellent hunch! I've nailed it. It's quite unrelated to the `RnTypes` Lint failure, I think. What's happening is that a function with a RULE is getting a new unique, but that unique isn't being propagated into the record representing the RULE itself. Fixing it now.

Well I don't see that it makes a great deal of difference. We have parsers and printer functions for both formats anyway. The Read/Show format is more fragile when it comes to adding fields. The Read/Show format is not necessarily faster. The non-Read/Show format is easier to read and debug I think. I think the ghc-pkg flags have grown a bit crufty; perhaps we should rethink them for 6.10? Yes. For example it is currently extremely hard to find the packages of a given name in a specific package database. The list and field commands always search all packages (global, user, explicitly specified). -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/1839#comment:2 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

I am building GHC 6.8.1 from source tarballs:

However, the Building guide [wiki:Building/Prerequisites]
says
If you start from a source tarball of GHC (i.e. not a darcs checkout),
then you don't need Happy, because we supply the pre-processed versions of
the Happy parsers.
I have been able to repeat this problem both on an i386 Debian Etch system
and a x86_64 RHEL4 system.
The workaround is to install happy.

[GHC] #1860: GMP dyn link dependencies in binary distributions
#1860: GMP dyn link dependencies in binary distributions -+-- Reporter: chak | Owner: Type: bug | Status: new Priority: normal| Milestone: 6.8.2 Component: Build System | Version: 6.8.1 Severity: major |Keywords: Difficulty: Unknown |Testcase: Architecture: Unknown | Os: MacOS X -+-- A binary distribution contains a couple of ghc compiled binaries (most notably `pwd` and `ghc-pkg` from the `utils/` directory) that are linked by the '''bootstrap compiler''' (i.e., the compiler also used to compile stage1). As result, these binaries include dependencies on those versions of dynamic libraries used by the bootstrap compiler. This can be fatal if the build machine has dynamic libraries that the machine where the binary distribution is installed doesn't have (in particular, this can be a problem with gmp on Mac OS X). Here an example: 1. Machine A has a macports installation of GHC 6.6.1 that is dependent on and uses macport's gmp. 2. Machine A is used to generate a binary distribution for GHC 6.8.1, where the 6.6.1 compiler is used as the bootstrap compiler. The resulting GHC compiled binaries in the `utils/` directory of the generated distribution will now depend on the macports version of gmp. 3. Machine B has no gmp installed (which should be ok as the binary distribution has a version of gmp embedded which the newly installed compiler will use). 4. When invoking `./configure` on Machine B, `utils/pwd` of the binary distribution will be invoked which looks for the macports version of gmp in vain and fails. This is a fundamental problem with dynlib dependencies, esp on gmp, which will affect all architectures to varying degrees. However, it is especially bad for Mac OS X, as the obvious solution - to link the binaries generated by the bootstrap compiler '''statically''' - does not work on Mac OS X (at least it does not on 10.5). It the flag `-optl- static` is supplied, linking fails complaining that a library `crt.o` could not be found. -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/1860 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
