Eli Friedman 149614bfe7 Re-fix r51907 in a way which doesn't affect valid code. This essentially
moves the check for the invalid construct to a point where it doesn't 
affect other uses of isIntegerConstantExpr, and we can warn properly 
when the extension is used.  This makes it a bit more complicated, but 
it's a lot cleaner.

Steve, please tell me if this check is sufficient to handle the 
relevant system header.  I know it's enough to handle the testcase, but 
I don't know what exactly the original looks like.

Ted Kremenek 380df93fd6 Added "InitializeTU" to ASTConsumer. This is used by Sema::ParseAST to pass a
TranslationUnit object instead of an ASTContext. By default it calls
Initialize(ASTConstext& Context) (to match with the current interface used by
most ASTConsumers).

Modified the ObjC-Rewriter to use InitializeTU, and to tell the TranslationUnit
to not free its Decls.  This is a workaround for: <rdar://problem/5966749>

Eli Friedman aee9e54dca Don't swap function decls, and add them to the scope as they are
encountered.  Mixing up the decls is unintuitive, and confuses the AST 
destruction code. Fixes PR2360.

Note that there is a need to look up the characteristics and 
declarations of a function associated with a particular name or decl, 
but the original swapping code doesn't solve it properly. 
http://lists.cs.uiuc.edu/pipermail/cfe-dev/2008-May/001644.html is one 
suggestion for how to fix that.

Ted Kremenek ce20e8fe8d Try to plug some memory leaks...
1) Sema::ParseAST now constructs a TranslationUnit object to own the top-level Decls, which releases the top-level Decls upon exiting ParseAST.

2) Bug fix: TranslationUnit::~TranslationUnit handles the case where a Decl is added more than once as a top-level Decl.

3) Decl::Destroy is now a virtual method, obviating the need for a special dispatch based on DeclKind.

3) FunctionDecl::Destroy now releases its Body using its Destroy method.

4) Added Stmt::Destroy and Stmt::DestroyChildren, which recursively delete the child ASTs of a Stmt and call their dstors.  We may need to special case dstor/Destroy methods for particular Stmt subclasses that own other dynamically allocated objects besides AST nodes.

5) REGRESSION: We temporarily are not deallocating attributes; a FIXME is provided.

Ted Kremenek 467297ab48 TranslationUnit now owns IdentifierTable, TargetInfo, and Selectors objects
when it is constructed via deserialization.  This is done by recording a flag
indicating that this is the case, and it deletes these objects by getting
the references stored in the ASTContext object.  This fixes some memory
leaks that occurs when we deserialize translation units from bitcode files.

The rationale between having TranslationUnit sometimes own these objects and
sometimes not is that a TranslationUnit object can be constructed from
state generated by the parser (Preprocessor; semantic analyzer, etc.), and thus
in these cases won't own the IdentifierTable or Selectors, etc.  During
deserialization, there is no Preprocessor, so somebody needs to own these
objects in order for them to be properly reclaimed.

: To be consistent with FieldDecl::getContextDecl(), which serves the same purpose.
: From my perspective, getContext() is too general (and used by several other classes for different purposes).

-Added ContextDecl (no TranslationUnitDecl)
-ScopedDecl class has a ContextDecl member
-FieldDecl class has a ContextDecl member, so that a Field or a ObjCIvar can be traced back to their RecordDecl/ObjCInterfaceDecl easily
-FunctionDecl, ObjCMethodDecl, TagDecl, ObjCInterfaceDecl inherit from ContextDecl. With TagDecl as ContextDecl, enum constants have a EnumDecl as their context.
-Moved Decl class to a "DeclBase.h" along with ContextDecl class
-CurContext is handled by Sema

Chris Lattner a21ad8058a Fix several bugs in array -> pointer decomposition.
First, we got several CVR propagation cases wrong, which Eli pointed
out in PR2039.

Second, we didn't propagate address space qualifiers correctly, leading
to incorrect lowering of code in CodeGen/address-space.c.

Third, we didn't uniformly propagate the specifier in the array to the
pointer ("int[restrict 4]" -> "int *restrict").

This adds an ASTContext::getArrayDecayedType member that handles the 
non-trivial logic for this seemingly simple operation.

Steve Naroff 257520b1b4 Fairly large "cleaup" related to changing ObjCCompatibleAliasDecl superclass (to inherit from NamedDecl, instead of ScopedDecl).
- Added a DenseMap to associate an IdentifierInfo with the ObjCCompatibleAliasDecl.
- Renamed LookupScopedDecl->LookupDecl and changed it's return type to Decl. Also added lookup for ObjCCompatibleAliasDecl's.
- Removed Sema::LookupInterfaceDecl(). Converted clients to used LookupDecl().
- Some minor indentation changes.

Fix objc ivar lookup.  Ivar lookup should occur between lookup
of method-local values and lookup of globals.  Emulate this with
some logic in the handling of Sema::ActOnIdentifierExpr.

Two todo's left:
 1) sema shouldn't turn a bare reference to an ivar into "self->ivar"
    in the AST.  This is a hack.
 2) The new ScopedDecl::isDefinedOutsideFunctionOrMethod method does
    not correctly handle typedefs and enum constants yet.

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.
