Comment(by rl):

 I doubt it's the fusion framework (which does work, just not as well as it
 used to before the typechecker patch). If the ghc package is getting
 linked in then that is probably the reason for the binary size. The
 package is only used for one thing by vector: annotations to drive
 !SpecConstr. That is, I only use a single data type and no functions from
 package ghc. Why would GHC link in the entire package in that case?

 Thank you for the detailed reply, Simon. I'm currently working for George
 and his research group and I'm going to take on this task in the next
 couple of weeks. Those advices will be a great help.

Comment(by simonpj):

 Moreover, the annotations stuff, and hence the `ghc` package is only used
 at ''compile time''.  So it should not be linked at run time.  There
 should be literally no references to `ghc` in the `.o` files, so it should
 not be linked at all.

 that it renders it obsolete.  Should the patch include removing the {{{:{

Comment(by simonmar):

 I don't know how well Haskeline will cope with multi-line input.  Ideally
 you want Haskeline to be able to navigate and edit the complete multi-line
 expression.

 Also I'm not sure how layout should behave with the prompt, because the
 first line is already indented: should subsequent lines be indented by the
 width of the prompt, or should there be a special multi-line continuation
 prompt?

 Since fusion/inlining doesn't happen with -O0, that pretty much means that

 One way to track it down would be to issue the link command manually with

Comment(by gwright):

 Now I know what the bug is: relocations of type `X86_64_RELOC_GOT` and
 `X86_64_RELOC_GOT_LOAD` are not handled by the Mach-O linker.  There is a
 stub of code for these cases, but it does something nonsensical.  I'm
 guessing it was simply never finished.

 This doesn't seem too hard to fix, but it's fiddly.  If I'm lucky and my
 current hunch works, maybe a patch in a couple of days. Otherwise, I'll
 need to try to understand Apple's ld64 code to understand these
 relocations in more detail.

Comment(by simonpj):

 Ah.. light dawns.

 Every module has a module-initialisation routine.  Apart from initialising
 the module, it calls the module-initialisation routine for each imported
 module.  So if M imports module `SpecConstr` from package `ghc`, then the
 module-initialisatin routine for M will call the initialisation routine
 for `SpecConstr`.  Even though nothing from `SpecConstr` is ultimately
 used.

 Hmm.  That is bad.  I'm not sure what to do about it. The obvious
 alternative is to call the module-init routine for each `Id` mentioned in
 the final executable for M.  That would solve the problem, but at a cost:
 every module will call zillions of module initialisers.

Comment(by daniel.is.fischer):

 Yeah, seems that's it,
 {{{
 #if __GLASGOW_HASKELL__ = 613
 import SpecConstr ( SpecConstrAnnotation(..) )
 #endif
 }}}
 means !SpecConstr isn't actually imported with 6.12.

Comment(by josef):

 It seems to me that what is really needed is a form of compile time
 imports. Some way to indicate that an imported module will only be used at
 compile time, for instance to use annotations or to generate code using
 Template Haskell.

 Jonas Almström Duregård bumped in to the same problem when using Template
 Haskell. He needed to import modules for use only at compile time but they
 where also linked in when the binary was created. Link to email:
 http://www.haskell.org/pipermail/glasgow-haskell-
 users/2010-September/019211.html

Comment(by rl):

 Could we just use `collect2` to collect and execute all initialisers that
 are linked in? GCC already solves this problem for C++ so perhaps we could
 simply reuse their mechanism.

Comment(by rl):

 I thought that `collect2` automates this. IIRC, it ploughs through all
 object files looking for specific constructor symbols and then generates
 and links in an additional module which calls those symbols and is, in
 turn, called at start up. Wouldn't it be enough to simply make sure that
 module initialiser symbols look like constructors and link with
 `collect2`?

unused record fields

2010-10-15 Thread Serge D. Mechveliani
Simon P. Jones  wrote recently about that  ghc-6.12  takes in 
account the elliplis in  MkT {t1 = x, ..}  when reporting about 
unused bindings.

Now, here is the example: 

  module TT where
  data T = T {t1, t2 :: Int}

  f d = x  where
   T {t1 = x, ..} = d

ghc-6.12.2  warns about unused value of  t2.
And forf (T {t1 = x, ..}) = x,  
it does not warn about this.

Is this a bug?

I use
extensions: TypeSynonymInstances UndecidableInstances FlexibleContexts 
FlexibleInstances MultiParamTypeClasses OverlappingInstances
RecordWildCards NamedFieldPuns
ghc-options: -fno-warn-overlapping-patterns -fwarn-unused-binds 
 -fwarn-unused-matches -fwarn-unused-imports 
 -O0
, 
but the options can be simplified, of course.

Regards,

Comment(by nominolo):

 Benchmarks checking whether changing associativity of () in `pretty`
 would lead to performance issues:

 {{{
 import Text.PrettyPrint

 import Data.List
 import Criterion.Main


 f_left :: Int - Doc
 f_left n = foldl' () empty (map (text . show) [10001..1+n])

 f_right :: Int - Doc
 f_right n = foldr () empty (map (text . show) [10001..1+n])

 main =
   defaultMain $
 [ bench left $ nf (length . render . f_left)  1
 , bench right$ nf (length . render . f_right) 1
 , bench left20k  $ nf (length . render . f_left)  2
 , bench right20k $ nf (length . render . f_right) 2
 , bench left30k  $ nf (length . render . f_left)  3
 , bench right30k $ nf (length . render . f_right) 3
 ]
 }}}

 Results (lower numbers are better):

 {{{
Iterations
   _10K__20K__30K
 Left   10.1 (0.5)   24.4 (0.6)   40.0 (1.3)
 Right   8.9 (0.2)   22.7 (3.1)   31.2 (4.6)

 Format:  runtime (stddev) all in milliseconds
 }}}

 So switching to right-associativity may actually increase performance
 slightly.  Scaling doesn't seem to be quite linear, but that could be due
 to cache effects or suchlike; and it's also outside the scope of this
 proposal.

Comment(by batterseapower):

 Having a better solution for compile time imports would also prevent GHC
 from linking in modules that are import only for their type information
 (e.g. a type-level natural numbers package).

 We could also extend it so we get a better solution to the outstanding
 annoying problem where you have to remember to call `hs_init` and
 `hs_add_root` when building a C program that links in some Haskell. We can
 just arrange that hs_init is marked as a constructor for collect2's
 purposes. This will cause libgcc library to call hs_init for you (via
 __main), along with the module initialisers.

 This means that if you build your Haskell-importing C program using the
 GNU toolchain, then you don't have to worry about starting up the Haskell
 RTS at all. In particular this means you could write a Haskell library
 that behaves as a drop-in replacement for a C library.

Comment(by nominolo):

 Getting rid of `mappend` would break a ''lot'' of packages, so that will
 take a while.  Also, what should happen to `mconcat`?  The naming of
 `mappend` makes somewhat sense, because `[a]` is the free Monoid, so
 `mconcat` is just the extension of that naming strategy.  Should `mconcat`
 stay as is, or can anyone think of a better name?

 When benchmarking Containers, I came over some suspicious increase of code
 size. I reduced the test case to the following:

 Compile the following trivial benchmark:
 {{{
 import Data.Set
 import Criterion.Main

 main = defaultMain [bench set (whnf (length . toList . fromList . concat
 . replicate 10) [1..1000])]
 }}}

 The size of a stripped binary produced by ghc --make -O:
 {{{
 ghc-6.12.1:  2414128
 ghc-7.0.0.20100930: 22572260
 ghc-7.1.20101010:   21417316
 }}}

 That is nearly 10-times increase of code size. I could not figure out why.
 When using only 'base' package, there is nearly no increase in code size.
 The ghc-bundled libraries use -split-objs, the libraries compiled by
 cabal-install are not using -split-objs in any ghc version.

 I used I386. The ghc-6.12.1 is precompiled binary, ghc-7.0.0 is compiled
 by ghc-6.12.1 by using default build system (configure  make, no
 build.mk), ghc-7.1 is compiled by ghc-6.12.1 by using custom build.mk (but
 it only sets !GhcLibWays=v).

 The criterion package was compiled using 'cabal install criterion'. Latest
 version 0.5.0.4 was used (vector 0.7, vector-algorithms 0.3.3, statistics
 0.8.0.1). For ghc-7.0 and ghc-7.1 some minor changes to the latest hackage
 versions of the deepseq, parallel, syb and vector-algorithms packages had
 to be made (trivial dependency changes, code that does not type check).
 !SimonMar said some of that is already corrected in darcs repos.

 Can anyone reproduce this behaviour? If so, it is horrible.

 This is because the `ghc` packages is used, and thus linked in, with ghc
 7. See #4387 for more discussion.

 With this module:

 module TT where

 f :: T - Int
 f d = x
 where T {t1 = x, ..} = d

 `f` gives warnings about t2 being unused:
 {{{
 $ ghc -Wall -c n.hs

 n.hs:9:11: Warning: Defined but not used: `t2'

 which is probably not what we want for variables bound by a wildcard.

Comment(by gwright):

 I have ghci from HEAD working, built 64 bit on OS X 10.6.  At least it
 works well enough to define `fact` and `fib` at the prompt and get the
 right answers.  (Certainly an improvement over a segfault or abort trap!)

 I'll resync with HEAD and apply my patches, then run the testsuite.  There
 may still be some other problems with the linker lurking, since there have
 clearly been paths through the code that were never exercised in the 64
 bit Mach-O case.

 The final change to fix the crash wasn't much; better to be lucky than
 smart.

 close shave, though.

Comment:

 Works now :)

 Please test on 64 bits to make sure I haven't bungled the CPP stuff.

 I also have a lot of rewrite rules for !IntN and !WordN, but I'm not sure
 where to put them.
 Probably GHC.Int and GHC.Word, but we'd have to import GHC.Float and
 perhaps GHC.Float.RealFracMethods then.

Comment(by SamAnklesaria):

 I've come across a problem with making `if` syntax into a function. Many
 uses from GHC's base library are for branches with kind # that don't match
 the * kind expected by my polymorphic `ifThenElse` function. I could
 switch all such occurrences to `case` statements, but that wouldn't
 prevent other libraries from having the same problems. Is there any way to
 make polymorphic (Bool - a - a - a) functions handle things like Int#?
 I'm kinda stuck. Thanks.
