[mingw/msys only]
Undo long-standing workaround for buggy GNU ld's on mingw/msys; i.e.,
the linker wasn't correctly generating relocatable object files when
the number of relocs exceeded 2^16. Worked around the issue by
hackily splitting up the GHCi object file for the larger packages
('base', 'ObjectIO' and 'win32') into a handful of object files,
each with a manageable number of relocs. Tiresome and error-prone
(but the hack has served us well!)
This commit imposes a restriction on the 'ld' you use to compile
up GHC with; it now has to be ld-2.15.x or later (something GHC

that when we renamed the bracket we messed up the name cache, because
the module was still that of the parent module. Now we set a fake
module before renaming it.
TH_spliceDecl4 is the test.
(2) An expression splice can in principle mention *any* variable,
so the renamer really has to assume that it does when doing depdendency
analysis. For example
f = ...
h = ...$(thing "f")...
The renamer had better not put 'h' before 'f', else the type checker
won't find a defn for 'f' in the type envt.

thread, then the Task may have been already woken up on another
Capability, so the scheduler can't use task->cap to find the

this action is invoked for every message generated by the
compiler. This means a client of the GHC API can direct messages to
any destination, or collect them up in an IORef for later

This replaces previous hacks to redirect messages in the GHC API

- The JustTypecheck mode of GHC now does what it says. It doesn't

Big re-hash of the threaded/SMP runtime
This is a significant reworking of the threaded and SMP parts of
the runtime. There are two overall goals here:
- To push down the scheduler lock, reducing contention and allowing
more parts of the system to run without locks. In particular,
the scheduler does not require a lock any more in the common case.
- To improve affinity, so that running Haskell threads stick to the
same OS threads as much as possible.
At this point we have the basic structure working, but there are some
pieces missing. I believe it's reasonably stable - the important
parts of the testsuite pass in all the (normal,threaded,SMP) ways.
In more detail:
- Each capability now has a run queue, instead of one global run
queue. The Capability and Task APIs have been completely
rewritten; see Capability.h and Task.h for the details.
- Each capability has its own pool of worker Tasks. Hence, Haskell
threads on a Capability's run queue will run on the same worker
Task(s). As long as the OS is doing something reasonable, this
should mean they usually stick to the same CPU. Another way to
look at this is that we're assuming each Capability is associated
with a fixed CPU.
- What used to be StgMainThread is now part of the Task structure.
Every OS thread in the runtime has an associated Task, and it
can ask for its current Task at any time with myTask().
- removed RTS_SUPPORTS_THREADS symbol, use THREADED_RTS instead
(it is now defined for SMP too).
- The RtsAPI has had to change; we must explicitly pass a Capability
around now. The previous interface assumed some global state.
SchedAPI has also changed a lot.
- The OSThreads API now supports thread-local storage, used to
implement myTask(), although it could be done more efficiently
using gcc's __thread extension when available.
- I've moved some POSIX-specific stuff into the posix subdirectory,
moving in the direction of separating out platform-specific
implementations.
- lots of lock-debugging and assertions in the runtime. In particular,
when DEBUG is on, we catch multiple ACQUIRE_LOCK()s, and there is
also an ASSERT_LOCK_HELD() call.
What's missing so far:
- I have almost certainly broken the Win32 build, will fix soon.
- any kind of thread migration or load balancing. This is high up
the agenda, though.
- various performance tweaks to do
- throwTo and forkProcess still do not work in SMP mode

Small simplifier bug in case optimisation
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The simplifier eliminates redundant case branches, and panics if there
are no case alternatives. But due to a slightly delayed instantiation
of a type constructor variable 'p' by a type constructor 'P', it turned
out that an inner case had no alternatives at all, becuase an outer case
had not pruned a branch as quickly as it should have.
This commit fixes both problems:
a) SimplUtils.mkCase1 now returns a call to 'error' (instead of panicing)
when it gets an empty list of alternatives. Somewhat analogous to
the inaccessible GADT case in Simplify.simplifyAlt
b) In SimplUtils.prepareDefault, use the up-to-date scrutinee, rather than
the less up-to-date case_bndr, to get the case type constructor. That
leads to slightly earlier pruning of inaccessible branches.
Fixes a bug reported by Ian Lynagh.

Add record syntax for GADTs
~~~~~~~~~~~~~~~~~~~~~~~~~~~
Atrijus Tang wanted to add record syntax for GADTs and existential
types, so he and I worked on it a bit at ICFP. This commit is the
result. Now you can say
data T a where
T1 { x :: a } :: T [a]
T2 { x :: a, y :: Int } :: T [a]
forall b. Show b =>
T3 { naughty :: b, ok :: Int } :: T Int
T4 :: Eq a => a -> b -> T (a,b)
Here the constructors are declared using record syntax.
Still to come after this commit:
- User manual documentation
- More regression tests
- Some missing cases in the parser (e.g. T3 won't parse)
Autrijus is going to do these.
Here's a quick summary of the rules. (Atrijus is going to write
proper documentation shortly.)
Defnition: a 'vanilla' constructor has a type of the form
forall a1..an. t1 -> ... -> tm -> T a1 ... an
No existentials, no context, nothing. A constructor declared with
Haskell-98 syntax is vanilla by construction. A constructor declared
with GADT-style syntax is vanilla iff its type looks like the above.
(In the latter case, the order of the type variables does not matter.)
* You can mix record syntax and non-record syntax in a single decl
* All constructors that share a common field 'x' must have the
same result type (T [a] in the example).
* You can use field names without restriction in record construction
and record pattern matching.
* Record *update* only works for data types that only have 'vanilla'
constructors.
* Consider the field 'naughty', which uses a type variable that does
not appear in the result type ('b' in the example). You can use the
field 'naughty' in pattern matching and construction, but NO
SELECTOR function is generated for 'naughty'. [An attempt to use
'naughty' as a selector function will elicit a helpful error
message.]
* Data types declared in GADT syntax cannot have a context. So this
is illegal:
data (Monad m) => T a where
....
* Constructors in GADT syntax can have a context (t.g. T3, T4 above)
and that context is stored in the constructor and made available
when the constructor is pattern-matched on. WARNING: not competely
implemented yet, but that's the plan.
Implementation notes
~~~~~~~~~~~~~~~~~~~~
- Data constructors (even vanilla ones) no longer share the type
variables of their parent type constructor.
- HsDecls.ConDecl has changed quite a bit
- TyCons don't record the field labels and type any more (doesn't
make sense for existential fields)
- GlobalIdDetails records which selectors are 'naughty', and hence
don't have real code.

Fix a bug in TcUnify.unifyTyConApp that made a GADT program fail.
The trouble happens if the type that we are expecting to be
a TyConApp is of form (m a b), where 'm' is refined to a type
constructor. Then we want to get nice rigid results, and we weren't.

when a library listed in extraLibraries ends with "_cbits", append "_dyn"
when -dynamic is passed, i.e. extraLibraries = ["foo", "HSbase_cbits"]
loads -lfoo and -lHSbase_cbits in the static case, but -lfoo and
-lHSbase_cbits_dyn in the -dynamic case.
It's an ugly hack, but it affects only the case when -dynamic is passed,
which would not work otherwise right now, so let's
