Ignore-this: ba9668f8a031fec7a2c94b421a58d79f
This patch adds a new type class (Annotated), following the Annotated class in haskell-src-exts.
All AST nodes already have type variables, but sometimes we forgot to use the right type; this is fixed
now. All AST nodes are now instances of both Annotated (read and change annotation at a node) and fmap
(change the type of annotations for the syntax tree as a whole). Furthermore, the automated derivation
scripts have been ported to derive-2, and now use Haskell.Src.Exts instead of Template Haskell.

[Fix type checking bug for function pointer parameters.
Aaron Tomb <aarontomb at gmail.com>**20100127172548
The previous patch to add support for transparent unions broke type
checking of paramters to functions passed via function pointers. If a
function was defined to take a parameter that was a typedef name, and
you passed in a function in which the matching parameter was the raw
type referred to by that typedef, the two would not match because the
type checker was failing to dereference typedef names in this one case.

other analysis code can replace the annotations.
The parametric AST types have longer, less abbreviated names. For
instance, statements are now
data CStatement a = ...

type CStat = CStatement NodeInfo

Aaron Tomb <aarontomb at gmail.com>**20091112193809
Previously, subtraction was allowed on pointers but not arrays. This

Eventually, it might be best to refactor the type checker a bit to
support array->pointer coercion in the right places.

[Fix awkward array type checking.
Aaron Tomb <aarontomb at gmail.com>**20090927200632
Array type checking was somewhat broken before. During a moment of
frustration (because some key type checking code was incorrect), I
decided to convert array types to pointer types immediately after
getting them out of the symbol table, to simplify type checking.
Unfortunately, this meant that the types returned by tExpr were never
array types, even when they should be.
The other bits of the type checker are in much better shape now, so this
egregious hack isn't necessary.
]
[Use pattern matching instead of partial function
Aaron Tomb <aarontomb at gmail.com>**20090816213828
Some type checking code used the partial identOfName function in a case
expression that was already pattern matching on the structure of
VarName. It's shorter and safer to extract the field directly in this
case.

[Replace CStorageSpec Show instance with Pretty instance
Aaron Tomb <aarontomb at gmail.com>**20090816185348
CStorageSpec had a Show instance specified in L.C.Syntax.AST, but no
other data type did. This Show instance was only used in one place, and
it seemed somewhat inconsistent with the rest of the code. So I removed
the Show instance from L.C.Syntax.AST, added a Pretty instance in
L.C.Pretty, and changed the one place that used the Show instance to use
the Pretty instance instead.
This could potentially cause incompatibilities with client code, but
it's unlikely: how often does code need to render storage specifications
as text but nothing else? Any broken code can be fixed with minimal
effort.
]
[Add constant expression evaluation.
Aaron Tomb <aarontomb at gmail.com>**20090802235355
This patch adds basic support for constant expression evaluation. Not
all cases are handled yet: alignof is not implemented, and the values
from the initializers for const globals are not yet used.
This patch also enables proper type checking of the GCC extension
__builtin_choose_expr, which depends on constant expression evaluation.
]
[Tighten a bunch of class contexts.
Aaron Tomb <aarontomb at gmail.com>**20090725044519
The separation of MonadTrav into several smaller monads makes it
possible to give more precise types to a number of functions. Many
functions that previously included the MonadTrav class constrain now
have one or both of MonadCError and MonadSymtab. They never need to
generate fresh names or call 'handleDecl'.
]
[Split MonadTrav into several monads
Aaron Tomb <aarontomb at gmail.com>**20090724011254
The MonadTrav class serves several purposes, and some useful functions
only need some of its available methods. This patch splits it into
several monads:
* MonadName, for fresh name generation.
* MonadSymtab, for symbol table operations.
* MonadCError, for C-specific error handling.
* MonadTrav, combining all of the above, plus a callback function.
]
[Refactor type checking a bit.
Aaron Tomb <aarontomb at gmail.com>**20090723012504
Now many of the utility functions in the type checker are pure
functions, returning Left on error. Clients in the MonadTrav monad can

[Export getUserState and tDesignator
Aaron Tomb <aarontomb at gmail.com>**20090716234346
The former is necessary for user state to be at all useful. The latter

least one project, so it seems worth exporting.

[Record use/def link between names.
Aaron Tomb <aarontomb at gmail.com>**20090222200922
The DefTable type included a refTable field to record links between use
and definition Names, but it was unused. Now, whenever analysis code
calls lookupTypeDef or lookupObject, the link between use and definition
is store in the refTable. Type checking should fully populate this
table, because it needs to lookup all uses to ensure that their use is
well-typed.
]
[Only analyse TypeSpecs once. Fixes #29.
Aaron Tomb <aarontomb at gmail.com>**20090222183955
Previously, the type specifiers of declarations with multiple
declarators were analyzed multiple times. However, when declaring a
variable with the same name as a type, this causes problems.
Consider:
foo *foo, *bar;
The analysis of "foo *foo" results in a symbol table where the innermost
definition of "foo" refers to an object, not a typedef name.
Therefore, when analyzing "foo *bar", the type checker tries to look up
"foo" and gets an object declaration, which is a type error.
Code like the above example does actually occur, and is valid C. The
seemingly equivalent:
foo *foo;
foo *bar;
is not valid C, and is rejected as it should be. The second line is seen
as an expression statement, multiplying foo and bar, and fails because
bar is not in scope.

[[Position, Lexer] Don't export any constructors for Position
joe.thornber at gmail.com**20090126094323
Instead use the provided operators to query/update a position. Only
the lexer was effected by this. I hope this doesn't impact
performance too much.

[[Position] Use record syntax when defining Position
joe.thornber at gmail.com**20090126091403
That way we get pos{Row,File,Offset,Column} defined for free.
]
[[Position] Use a summation type for the various position types.
joe.thornber at gmail.com**20090126085013
Rather than using magic values for the row and column field I
think it's cleaner to just define some new constructors for
<builtin position> etc. The only reason I can see for the way
it was is performance/memory. But if that was the case Position
would have been defined with newtype.

Maybe we should change Position to

? This seems more consistent than the currently used

Need to think about this a little bit.

Aaron Tomb <aarontomb at gmail.com>**20081230190851

[Code to merge name spaces and definition tables
Aaron Tomb <aarontomb at gmail.com>**20081211003525
It can be useful to merge symbol tables on occasion. It doesn't make any
sense to do this if they disagree about the values associated with their
respective keys, but there are many cases when you can guarantee that
they will agree.

[Typedefs can be block scoped
Aaron Tomb <aarontomb at gmail.com>**20081209003218
Under certain circumstances, the standard says that typedefs have block
scope. GCC seems even more liberal, treating typedefs just like any
other identifier, with scope extending to the end of the innermost
block. To handle code such as Linux, we now do the same.
]
[Fix corner cases in compound initializer checking
Aaron Tomb <aarontomb at gmail.com>**20081209002952
Compound array and structure initializer lists with complex combinations of
designated and undesignated elements now type check. The bulk of Linux
2.6.24.3 now goes through with only one error.

[Fix fiddly bits of structure and union checking
Aaron Tomb <aarontomb at gmail.com>**20081206000054
Nested structures and unions weren't being handled correctly, especially
in initializers. Now we can check members of anonymous union members as
if they were direct members, and we can initialize nested structures.
For example, we now accept:
struct baz { int a; union { int b; int c; }; } v = { .a = 0, .b = 1 };
and
struct foo { int x; struct bar { int y; } inner; } z = { .x = 0, .inner.y = 1 };
]
[Allow void functions to return void expressions
Aaron Tomb <aarontomb at gmail.com>**20081205235436
There really is code (in Linux) that looks like this:
void g();
void f() { return g(); }
The standard doesn't allow it (6.8.6.4.1) but GCC does, so it seems
useful to allow it ourselves, too.
Eventually, it would make sense to have some configuration settings that
describe exactly which variant of the language to accept. In strict C99
mode, we'd reject this.
]
[Include anonymous structure members in analysis
Aaron Tomb <aarontomb at gmail.com>**20081205235158
When typechecking structure declarations, we previously skipped
anonymous members. Now anonymouse structure and union members are
included in the symbol table (and anonymous members of non-composite
type are rejected).
]
[Update linkage rules for redefinition
Aaron Tomb <aarontomb at gmail.com>**20081205230750
From my reading of the standard, it seems as though, if the original
declaration (or definition) of a function has internal linkage, then a
later declaration (or definition) can have either internal or external
linkage. GCC seems to agree with this.

[Move generally-useful functions to separate module
Aaron Tomb <aarontomb at gmail.com>**20081204225416
There is now a Language.C.Syntax.Utils module that contains useful
functions for dealing with ASTs. Right now, these include a
manually-written traversal to extract sub-statements and one to apply a
function to all sub-statements. These might be better written with some
sort of generic programming framework in the future.

Aaron Tomb <aarontomb at gmail.com>**20081203205009]
[Remove typeof as early as possible
Aaron Tomb <aarontomb at gmail.com>**20081202182528
Remove typeof when translating from C types to Types. This requires
DeclAnalysis to have the ability to typecheck expressions. I've decided
that making AstAnalysis and DeclAnalysis mutually recursive is the
simplest and cleanest way to do this for now.
]
[Typecheck initializers later (fixes #25)
Aaron Tomb <aarontomb at gmail.com>**20081202181725
Typecheck initializers after entering the variable they initialize into
the symbol table. For the moment, this works, but it will break if
Initializer becomes different from CInit.
]
[Add local labels in block scope.
Aaron Tomb <aarontomb at gmail.com>**20081202175734
This patch undoes my previous "fix" of getSubStmts and does things
properly inside getLabels, instead. Now, function-scope labels are all
added before we start type checking the function, and local labels are
added when entering the block they live in.
Ultimately, the utility functions getSubStmts, compoundSubStmts, and
getLabels probably belong somewhere in the Language.C.Syntax.*
hierarchy.
]
[Change block scopes to create new label scope, too.
Aaron Tomb <aarontomb at gmail.com>**20081202175442
This makes local labels work out properly. We should scan a function body
for non-local labels and add them all inside the initial function scope,
anyway, since labels can jump backward, so this shouldn't cause any
problems.

This is useful for debugging, primarily, so we can print typeof types.

[Initial import of type checker.
Aaron Tomb <aarontomb at gmail.com>**20081201230325
This patch adds a type checker for expressions and statements. It is
almost certainly incomplete at this point, but passes some tests.

[Add a module of type utility functions
Aaron Tomb <aarontomb at gmail.com>**20081201190109
These are all simple, pure functions for operating on types that are
