Remove old asserts from ASTContext::isObjcIdType() and isObjcClassType(). Instead, return false if the declarations aren't in scope. This was a hold over from when 'id' and 'Class' were initialized lazily.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43827 91177308-0d34-0410-b5e6-96231b3b80d8

Implemented serialization of IfStmt.

Fixed declarations of several "directEmit" methods of classes that subclass
Stmt that were missing a "virtual" keyword.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43814 91177308-0d34-0410-b5e6-96231b3b80d8

Teach ASTContext::tagTypesAreCompatible() about the built-in ObjC types (Class and id), removing a bogus warning.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43809 91177308-0d34-0410-b5e6-96231b3b80d8

Rewrite ObjC @try/@catch/@finally. Some minor tweaks to the AST nodes...

Still need to rewrite @throw (and do more testing)...

Start struct bit field laout work.
This is far from complete.

Added serialization/deserialization of NullStmts.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43797 91177308-0d34-0410-b5e6-96231b3b80d8

Added serialization/deserialization of DeclStmts.
Reordered stmt serialization method implementations to be in alphabetical order.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43796 91177308-0d34-0410-b5e6-96231b3b80d8

Overhauled serialization of statements.  We no longer use specialized SerializeTrait<> classes,
but methods in Stmt (like other objects we are serializing).  Full serialization of all statements
is not yet complete.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43793 91177308-0d34-0410-b5e6-96231b3b80d8

Added static inline method "ReadVal" to QualType for more succinct
deserialization code of objects containing QualTypes.

Started work on new serialization approach within ASTContext to
serialize Type objects in the order they are serialized in the Types
vector.  We also now rely on the methods within ASTContext to unique
Type objects and handle the actual creation of Type objects (these are
now called by the deserialization code).  This approach solves some
hairy issues with ownership of objects and allows us to naturally
handle recursive types.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43787 91177308-0d34-0410-b5e6-96231b3b80d8

QualType deserialization now requires that the underlying pointer type
must be deserialized without requiring backpatching.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43786 91177308-0d34-0410-b5e6-96231b3b80d8

Bug fix: inverted test condition to see if a serialized AST-bitcode

Patch for objc2's property ASTs, as well as pretty-priting the ASTs.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43778 91177308-0d34-0410-b5e6-96231b3b80d8

Misc. serialization changes to ASTContext and Decls.  Serialization
for ASTContext is still rapidly evolving.

Revampled Serialization Tester to serialize and deserialize out an entire ASTContext and top-level decls.

Fix a "basic" bug that resulted in a bogus SourceLocation.

Off hand, I don't know why this change makes a difference (I thought the two constructor idioms were equivalent).

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43770 91177308-0d34-0410-b5e6-96231b3b80d8

Added registration to deserialization engine of IdentifierInfo* as
IdentifierInfos are deserialized.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43741 91177308-0d34-0410-b5e6-96231b3b80d8

In driver code implemented serialization of ASTContext.  Working on serialization of simple ASTs.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43738 91177308-0d34-0410-b5e6-96231b3b80d8

Added skeleton for dispatch of Decl serialization.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43737 91177308-0d34-0410-b5e6-96231b3b80d8

For serialization of ASTContext, added special-casing of serialization
of type sets when emitting complex types and pointer types that are
also considered builtins.  These types are automatically created in
the ctor of ASTContext, and thus should not be serialized (was
producing an error during deserialization).

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43733 91177308-0d34-0410-b5e6-96231b3b80d8

Misc. fixes. 1) Resurrect meta-data generation turned off by a previous patch.
2) Fixed a regression in meta-data generation caused by removal of '_interface' prefix from synthesize class name.
3) Added stubs for @try/@catch/@finally statements.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43716 91177308-0d34-0410-b5e6-96231b3b80d8

Made methods "Emit" and "Materialize" in ASTContext (used for serialization) public.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43713 91177308-0d34-0410-b5e6-96231b3b80d8

Added TypeSerialization.cpp and DeclSerialization.cpp to the XCode project.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43710 91177308-0d34-0410-b5e6-96231b3b80d8

Sema::ActOnClassMessage()...if a class method isn't found, lookup an instance method. Since all classes are also instances, this is appropriate.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43708 91177308-0d34-0410-b5e6-96231b3b80d8

Declare objc_selector outside the prototype for objc_msgSend(), removing a silly warning.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43706 91177308-0d34-0410-b5e6-96231b3b80d8

Rewrite @selector(sel).

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43705 91177308-0d34-0410-b5e6-96231b3b80d8

- change the synthesized typedef (for classes) to be of type "objc_object".
- fix a couple bugs in RewriteObjCStringLiteral.
- convert "Class" -> "id" in RewriteMessageExpr.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43704 91177308-0d34-0410-b5e6-96231b3b80d8

Remove HandleObjcMetaDataEmission(), I inadvertantly resurrected it.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43690 91177308-0d34-0410-b5e6-96231b3b80d8

Two additions...

- Synthesize the funky cast for objc_msgSend(). For the basic case, it looks like...

((id (*)(id, SEL))(void *)objc_msgSend)(obj, sel);

The "void *" cast is needed to workaround a GCC "bandaid" (Chris says it has something to do with the inliner). Without the extra "void *" cast, we get spurious warnings/notes that look like...

xx.m:17: warning: function called through a non-compatible type
xx.m:17: note: if this code is reached, the program will abort

- Add prototypes for the ObjC functions we call, objc_msgSend/objc_getClass for now (don't depend on them being included).

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43685 91177308-0d34-0410-b5e6-96231b3b80d8

Fix ownership model of ParseAST to allow the dtor of
ASTConsumer to process the AST before it is destroyed.
This allows elimination of HandleObjcMetaDataEmission.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43659 91177308-0d34-0410-b5e6-96231b3b80d8

Provide both const and non-const accessor methods for @try and @finally ASTs.
My previous patch did the same for @catch AST.

Simplified Serialization code for SourceLocation and SourceRange, and
updated it to the recently updated Serialization API.

Changed clients of SourceLocation serialization to call the
appropriate new methods.

Updated Decl serialization code to put new skeleton serialization code
in place that is much better than the older trait-specialization
approach.

Implemented serialization of QualTypes within ASTContext.  Clarified
ownership model of some type pointers.  Added FIXMEs to serialization.

Added comments to ASTContext indicating which variables we are intentionally
*not* serializing.

Changed serialization/deserialization of BuiltinTypes to explicitly serialize
each type.  This ensures that the order in which the types are serialized
is clear and remains persistent.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43615 91177308-0d34-0410-b5e6-96231b3b80d8

Reverted unnecessary inlining of operator!=, since negating operator== is

Implemented more of serialization/deserialization for ASTContext.  We now
(hypothetically) read in/write out most of the types.  Bugs likely exist.

Fix two rewriter bugs:

- For @class, don't generate multiple typedefs.
- Handle the following edge case interface...

@interface NSMiddleSpecifier : NSObject {}

@end

...which was incorrectly being rewritten to...

struct _interface_NSMiddleSpecifier {
        struct _interface_NSObject _NSObject;
};
{}

Take 2.

Make target info available to clang code generator.  This is far from complete but this helps clang codegen module make progress.

At the moment target triplet and target description strings are hard coded in clang::TargetInfo
