FIX #2682: banish silly cases of the "module Foo is not loaded" error
In GHCi if you say 'import Foo' meaning to load a package module Foo,
and Foo.hs is found on the search path, then GHCi replies "module Foo
is not loaded", because it knows Foo refers to the source file rather
than the package module, and you haven't loaded that module with
:load.
This is consistent with the usual module-finding semantics. However,
it isn't particularly useful. And it leads to silly problems like not
being able to start GHCi when you happen to be sitting in
libraries/base, because GHCi thinks the Prelude hasn't been loaded.
So now I've made a slight change to the way that 'import M' works: if
M is loaded, then it refers to the loaded module, otherwise it looks
for a package module M. This does what the reporter of #2682 wanted,
and since it turns an error condition into meaningful behaviour it
can't break anything.
The only undesirable consequence is that 'import M' might refer to a
different M than ':load M'. Hopefully that won't lead to confusion.

FIX #2845: Allow breakpoints on expressions with unlifted type
It turns out we can easily support breakpoints on expressions with
unlifted types, by translating
case tick# of _ -> e
into
let f = \s . case tick# of _ -> e
in f realWorld#
instead of just a plain let-binding. This is the same trick that GHC
uses for abstracting join points of unlifted type.
In #2845, GHC has eta-expanded the tick expression, changing the
result type from IO a to (# State#, a #), which was the reason the
tick was suddenly being ignored. By supporting ticks on unlifted
expressions we can make it work again, although some confusion might
arise because _result will no longer be available (it now has
unboxed-tuple type, so we can't bind it in the environment). The
underlying problem here is that GHC does transformations like
eta-expanding the tick expressions, and there's nothing we can do to
prevent that.

Allow Haddock comments in type synonyms
We now use `ctypedoc` instead of `ctype` for type synonyms. `ctypedoc` was

Note:
* I've modified `ctypedoc` so it allows implicit parameters and equational
constraints, just like ctype.
* Since `ctypedoc` allows nested foralls, we now allow that in type synonyms.
* I have inlined some productions into gentypedoc so that there is now a
non-doc version of every production with a 'doc' suffix. (Stylistic change
only, which should make the code easier to follow).
* It would have been nice to simplify the grammar by unifying `ctype` and
ctypedoc` into one production, allowing comments on types everywhere (and
rejecting them after parsing, where necessary). This is however not possible
since it leads to ambiguity. The reason is the support for comments on record
fields:
> data R = R { field :: Int -- ^ comment on the field }
If we allow comments on types here, it's not clear if the comment applies
to 'field' or to 'Int'. So we must use `ctype` to describe the type.

The black hole concerned the computation of which type constructors

isProductTyCon there, since it triggers the black hole (very

Improve mkDupableCont; and fix Trac #3116
It turns out that, as a result of a change I made a few months ago to
the representation of SimplCont, it's easy to solve the optimisation
challenge posed by Trac #3116. Hurrah.
Extensive comments in Note [Duplicating StrictArg].

Avoid quadratic complexity in occurrence analysis (fix Trac #1969)
The occurrence analyser could go out to lunch in bad cases, because
of its clever loop-breaking algorithm. This patch makes it bale out
in bad cases. Somewhat ad-hoc: a nicer solution would be welcome.
See Note [Complexity of loop breaking] for the details.

Improve arity propagation in the specialiser
This patch makes the specialiser propagate arities a bit more
eagerly, which avoids a spurious warning in the simplifier.

update list of C math functions
Fix via C compilation of modules that import, say, log1p from math.h (#3117)
The list is based on preprocessing Stg.h with glibc 2.6.1 headers, and

Template Haskell: make reify aware of type families
- Reifying a type family returns a TH family declaration
- Reifying a data constructor from a data instance attributes that
constructor to the family (not the representation tycon)
- Ideally, we should have facilities to reify all type/data instances of a
given family (and the same for instances of a class). I haven't added that
here as it involves some API design.
