Ted Kremenek bc76c72f94 Remove support for ObjCMethodDecl attributes that appear between the
return type and the selector.  This is inconsistent with C functions
(where such attributes would be placed on the return type, not the the
FunctionDecl), and is inconsistent with what people are use to seeing.

Ted Kremenek 290fbb1d42 Hook up Sema support for attributes on Objective-C method declarations that
appear between the return type and the selector. This is a separate code path
from regular attribute processing, as we only want to (a) accept only a specific
set of attributes in this place and (b) want to distinguish to clients the
context in which an attribute was added to an ObjCMethodDecl.

Currently, the attribute 'objc_ownership_returns' is the only attribute that
uses this new feature. Shortly I will add a warning for 'objc_ownership_returns'
to be placed at the end of a method declaration.

Chris Lattner 5bbb3c8ad9 Push DeclGroup much farther throughout the compiler. Now the various
productions (except the already broken ObjC cases like @class X,Y;) in 
the parser that can produce more than one Decl return a DeclGroup instead
of a Decl, etc.

This allows elimination of the Decl::NextDeclarator field, and exposes
various clients that should look at all decls in a group, but which were
only looking at one (such as the dumper, printer, etc).  These have been
fixed.

Still TODO:

1) there are some FIXME's in the code about potentially using
DeclGroup for better location info.
2) ParseObjCAtDirectives should return a DeclGroup due to @class etc.
3) I'm not sure what is going on with StmtIterator.cpp, or if it can
   be radically simplified now.
4) I put a truly horrible hack in ParseTemplate.cpp.

I plan to bring up #3/4 on the mailing list, but don't plan to tackle
#1/2 in the short term.

Chris Lattner 83f095cc7e Introduce a new OpaquePtr<N> struct type, which is a simple POD wrapper for a
pointer.  Its purpose in life is to be a glorified void*, but which does not
implicitly convert to void* or other OpaquePtr's with a different UID.

Introduce Action::DeclPtrTy which is a typedef for OpaquePtr<0>.  Change the 
entire parser/sema interface to use DeclPtrTy instead of DeclTy*.  This
makes the C++ compiler enforce that these aren't convertible to other opaque
types.

We should also convert ExprTy, StmtTy, TypeTy, AttrTy, BaseTy, etc,
but I don't plan to do that in the short term.

The one outstanding known problem with this patch is that we lose the 
bitmangling optimization where ActionResult<DeclPtrTy> doesn't know how to
bitmangle the success bit into the low bit of DeclPtrTy.  I will rectify
this with a subsequent patch.

Sebastian Redl 726a0d9524 Put the invalid flag of OwningResult into the Action pointer.
This shrinks OwningResult by one pointer. Since it is no longer larger than OwningPtr, merge the two.
This leads to simpler client code and speeds up my benchmark by 2.7%.
For some reason, this exposes a previously hidden bug, causing a regression in SemaCXX/condition.cpp.

Douglas Gregor 82ac25e4a7 Unify the code for defining tags in C and C++, so that we always
introduce a Scope for the body of a tag. This reduces the number of
semantic differences between C and C++ structs and unions, and will
help with other features (e.g., anonymous unions) in C. Some important
points:

  - Fields are now in the "member" namespace (IDNS_Member), to keep
    them separate from tags and ordinary names in C. See the new test
    in Sema/member-reference.c for an example of why this matters. In
    C++, ordinary and member name lookup will find members in both the
    ordinary and member namespace, so the difference between
    IDNS_Member and IDNS_Ordinary is erased by Sema::LookupDecl (but
    only in C++!). 
  - We always introduce a Scope and push a DeclContext when we're
    defining a tag, in both C and C++. Previously, we had different
    actions and different Scope/CurContext behavior for enums, C
    structs/unions, and C++ structs/unions/classes. Now, it's one pair
    of actions. (Yay!)

There's still some fuzziness in the handling of struct/union/enum
definitions within other struct/union/enum definitions in C. We'll
need to do some more cleanup to eliminate some reliance on CurContext
before we can solve this issue for real. What we want is for something
like this:

  struct X {
    struct T { int x; } t;
  };

to introduce T into translation unit scope (placing it at the
appropriate point in the IdentifierResolver chain, too), but it should
still have struct X as its lexical declaration
context. PushOnScopeChains isn't smart enough to do that yet, though,
so there's a FIXME test in nested-redef.c

Chris Lattner bb8cc18788 fix some minor error recovery bugs in ParseObjCInterfaceDeclList
where it would reject @required in non-protocols, but then go
ahead and tag methods with required anyway.  Instead, if we see
this in something other than a protocol, just ignore the request.

Also, improve error recovery a bit when we see something bogus 
inside an interface.

Daniel Dunbar 4983df37a7 Add more Parser/Sema support for GCC asm-label extension.
- ActOnDeclarator now takes an additional parameter which is the
   AsmLabel if used. Its unfortunate that this bubbles up this high,
   but we cannot just lump it in as an attribute without mistakenly
   *accepting* it as an attribute.
 - The actual asm-label itself is, however, encoded as an AsmLabelAttr
   on the FunctionDecl.
 - Slightly improved parser error recovery on malformed asm-labels.
 - CodeGen support still missing...

Chris Lattner d7352d6801 minor cleanup to the actions interface to pass around SmallVectorImpl instead

Fix protocol lists to pass down proper location info, so we get diagnostics

@interface NSWhatever : NSObject <NSCopying>
                                  ^

instead of this:

t.m:3:44: error: cannot find protocol definition for 'NSCopying', referenced by 'NSWhatever'
@interface NSWhatever : NSObject <NSCopying>
                                           ^

Fariborz Jahanian de615836f3 Patch for:
1) objc ivar processing is split out of ActOnField into its own ActOnIvar method.
2) the new objc ivar action takes visibility info directly, eliminating 
  AllVisibilities in ParseObjCClassInstanceVariables.

llvm-svn: 49506
2008-04-10 23:32:45 +00:00
Chris Lattner a12405b0ef refactor Parser::ParseStructDeclaration to return a vector of uninterpreted
declarators.  This allows the clients (C structs, objc classes, objc 
properties, [future] C++ classes) etc, to do custom processing before invoking
an action.

This has two benefits in the short term:
1) objc ivar processing should be split out of ActOnField into its own ActOn method.
2) the new objc ivar action can take visibility info directly, eliminating 
   AllVisibilities in ParseObjCClassInstanceVariables.
3) objc properties can pass their own special sauce down to sema as well.

Chris Lattner 7a51313d8a Make a major restructuring of the clang tree: introduce a top-level
lib dir and move all the libraries into it.  This follows the main
llvm tree, and allows the libraries to be built in parallel.  The
top level now enforces that all the libs are built before Driver,
but we don't care what order the libs are built in.  This speeds
up parallel builds, particularly incremental ones.
