have Destroy methods of ObjcMethodDecl and ObjCInterfaceDecl which recursively
destroy their owned Decls and Stmts. There are a few cases where it is not
clear what to do (FIXMEs included in the patch).

In addition to fixing the crasher, this commit fixes further improves property lookup (by searching protocols of qualified interfaces..."NSObject <prot>").

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.

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>

and union codepaths and fixes some minor bugs.
I'm reasonably confident this is accurate, at least for X86. I'll
correct any bugs as I find them; I haven't found any for a while,
though.

While it is far from complete, it does fix the following <rdar://problem/5967199> clang on xcode: error: member reference is not to a structure or union

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.

lib/CodeGen/CGExpr.cpp and to change include/clang/AST/Attr.h to
use its own enum for visibility types instead of using
llvm::GlobalValue::VisibilityTypes. These changes eliminate
dependencies in the AST library on LLVM's VMCore library.

Fixed a bug in ParmVarDecl::param_end(): Handle the case where there are no
ParmVarDecls for a FunctionDecl, but its function prototype has formal arguments
(can happen with typedefs).
llvm-svn: 51297
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.

The expected immediate usage is in *mmintrin.h, so that they don't

ScopedDecl with the backpatcher, and *not* a local variable on the stack. The

vector of the same element type and half the width, with the high, low, even,
and odd elements respectively.
Allow member references to member references, so that .hi.hi gives you the high
quarter of a vector. This is fairly convenient syntax for some insert/extract
operations.
Remove some unnecessary methods/types in the ExtVectorElementExpr class.

std::pair<CFGBlock*, CFGBlock*> that have an 8-byte alignment for use with
ProgramPoint. This fixes a bug reported by Argiris where using std::set<> on
Windows would result in a 4-byte alignment, not an 8-byte alignment.

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.

Added iterators, methods to find property and categories.
Use them in doing semantic analysis on property implementation
declarations. Fixed typos.
llvm-svn: 50050
Added assertion if unexpected property decls are found where they don't belong.
Consolidated property decl. printing by using a helper function.

-Added TranslationUnitDecl class to serve as top declaration context
-ASTContext gets a TUDecl member and a getTranslationUnitDecl() function
-All ScopedDecls get the TUDecl as DeclContext when declared at global scope

Refactored LiveVariables to use getTerminatorCondition() in VisitTerminator().
Bug fix: CFG now computes Block-level expression numbers using information
from block terminators. This fixes <rdar://problem/5868189>.

This is a fairly mechanical/large change. As a result, I avoided making any changes/simplifications that weren't directly related. I did break two Analysis tests. I also have a couple FIXME's in UninitializedValues.cpp. Ted, can you take a look? If the bug isn't obvious, I am happy to dig in and fix it (since I broke it).

allows the parsing of "class" in addition to "struct" and "union" to
declare a record. So this patch allows:
class C { };
class C c1;
But it does not contain the lookup bits, so this won't work yet:
C c2;

#1: To be consistent with FieldDecl::getContextDecl(), which serves the same purpose.
#2: From my perspective, getContext() is too general (and used by several other classes for different purposes).
llvm-svn: 49224
-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

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.

- 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.
Will deal with ObjCInterfaceDecl and getObjCInterfaceDecl() in a separate commit...

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.

it would get filled in later. Move the allocation+filling in to be more
consistent with other stuff, e.g. the addMethods method.

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.
