Make record selectors into ordinary functions
This biggish patch addresses Trac #2670. The main effect is to make
record selectors into ordinary functions, whose unfoldings appear in
interface files, in contrast to their previous existence as magic
"implicit Ids". This means that the usual machinery of optimisation,
analysis, and inlining applies to them, which was failing before when
the selector was somewhat complicated. (Which it can be when
strictness annotations, unboxing annotations, and GADTs are involved.)
The change involves the following points
* Changes in Var.lhs to the representation of Var. Now a LocalId can
have an IdDetails as well as a GlobalId. In particular, the
information that an Id is a record selector is kept in the
IdDetails. While compiling the current module, the record selector
*must* be a LocalId, so that it participates properly in compilation
(free variables etc).
This led me to change the (hidden) representation of Var, so that there
is now only one constructor for Id, not two.
* The IdDetails is persisted into interface files, so that an
importing module can see which Ids are records selectors.
* In TcTyClDecls, we generate the record-selector bindings in renamed,
but not typechecked form. In this way, we can get the typechecker
to add all the types and so on, which is jolly helpful especially
when GADTs or type families are involved. Just like derived
instance declarations.
This is the big new chunk of 180 lines of code (much of which is
commentary). A call to the same function, mkAuxBinds, is needed in
TcInstDcls for associated types.
* The typechecker therefore has to pin the correct IdDetails on to
the record selector, when it typechecks it. There was a neat way
to do this, by adding a new sort of signature to HsBinds.Sig, namely
IdSig. This contains an Id (with the correct Name, Type, and IdDetails);
the type checker uses it as the binder for the final binding. This
worked out rather easily.
* Record selectors are no longer "implicit ids", which entails changes to
IfaceSyn.ifaceDeclSubBndrs
HscTypes.implicitTyThings
TidyPgm.getImplicitBinds
(These three functions must agree.)
* MkId.mkRecordSelectorId is deleted entirely, some 300+ lines (incl
comments) of very error prone code. Happy days.
* A TyCon no longer contains the list of record selectors:
algTcSelIds is gone
The renamer is unaffected, including the way that import and export of
record selectors is handled.
Other small things
* IfaceSyn.ifaceDeclSubBndrs had a fragile test for whether a data
constructor had a wrapper. I've replaced that with an explicit flag
in the interface file. More robust I hope.
* I renamed isIdVar to isId, which touched a few otherwise-unrelated files.

Rollback INLINE patches
rolling back:
Fri Dec 5 16:54:00 GMT 2008 simonpj@microsoft.com
* Completely new treatment of INLINE pragmas (big patch)
This is a major patch, which changes the way INLINE pragmas work.
Although lots of files are touched, the net is only +21 lines of
code -- and I bet that most of those are comments!
HEADS UP: interface file format has changed, so you'll need to
recompile everything.
There is not much effect on overall performance for nofib,
probably because those programs don't make heavy use of INLINE pragmas.
Program Size Allocs Runtime Elapsed
Min -11.3% -6.9% -9.2% -8.2%
Max -0.1% +4.6% +7.5% +8.9%
Geometric Mean -2.2% -0.2% -1.0% -0.8%
(The +4.6% for on allocs is cichelli; see other patch relating to
-fpass-case-bndr-to-join-points.)
The old INLINE system
~~~~~~~~~~~~~~~~~~~~~
The old system worked like this. A function with an INLINE pragam
got a right-hand side which looked like
f = __inline_me__ (\xy. e)
The __inline_me__ part was an InlineNote, and was treated specially
in various ways. Notably, the simplifier didn't inline inside an
__inline_me__ note.
As a result, the code for f itself was pretty crappy. That matters
if you say (map f xs), because then you execute the code for f,
rather than inlining a copy at the call site.
The new story: InlineRules
~~~~~~~~~~~~~~~~~~~~~~~~~~
The new system removes the InlineMe Note altogether. Instead there
is a new constructor InlineRule in CoreSyn.Unfolding. This is a
bit like a RULE, in that it remembers the template to be inlined inside
the InlineRule. No simplification or inlining is done on an InlineRule,
just like RULEs.
An Id can have an InlineRule *or* a CoreUnfolding (since these are two
constructors from Unfolding). The simplifier treats them differently:
- An InlineRule is has the substitution applied (like RULES) but
is otherwise left undisturbed.
- A CoreUnfolding is updated with the new RHS of the definition,
on each iteration of the simplifier.
An InlineRule fires regardless of size, but *only* when the function
is applied to enough arguments. The "arity" of the rule is specified
(by the programmer) as the number of args on the LHS of the "=". So
it makes a difference whether you say
{-# INLINE f #-}
f x = \y -> e or f x y = e
This is one of the big new features that InlineRule gives us, and it
is one that Roman really wanted.
In contrast, a CoreUnfolding can fire when it is applied to fewer
args than than the function has lambdas, provided the result is small
enough.
Consequential stuff
~~~~~~~~~~~~~~~~~~~
* A 'wrapper' no longer has a WrapperInfo in the IdInfo. Instead,
the InlineRule has a field identifying wrappers.
* Of course, IfaceSyn and interface serialisation changes appropriately.
* Making implication constraints inline nicely was a bit fiddly. In
the end I added a var_inline field to HsBInd.VarBind, which is why
this patch affects the type checker slightly
* I made some changes to the way in which eta expansion happens in
CorePrep, mainly to ensure that *arguments* that become let-bound
are also eta-expanded. I'm still not too happy with the clarity
and robustness fo the result.
* We now complain if the programmer gives an INLINE pragma for
a recursive function (prevsiously we just ignored it). Reason for
change: we don't want an InlineRule on a LoopBreaker, because then
we'd have to check for loop-breaker-hood at occurrence sites (which
isn't currenlty done). Some tests need changing as a result.
This patch has been in my tree for quite a while, so there are
probably some other minor changes.

* Fix Trac #2861: bogus eta expansion
Urghlhl! I "tided up" the treatment of the "state hack" in CoreUtils, but
missed an unexpected interaction with the way that a bottoming function
simply swallows excess arguments. There's a long
Note [State hack and bottoming functions]
to explain (which accounts for most of the new lines of code).

* Revert CorePrep part of "Completely new treatment of INLINE pragmas..."
The original patch said:
* I made some changes to the way in which eta expansion happens in
CorePrep, mainly to ensure that *arguments* that become let-bound
are also eta-expanded. I'm still not too happy with the clarity
and robustness fo the result.
Unfortunately this change apparently broke some invariants that were
relied on elsewhere, and in particular lead to panics when compiling
with profiling on.
Will re-investigate in the new year.

as it was getting an ExitSuccess exception, but GHC API clients
