2010-02-23Add support for the weakref attribute. We still produce "alias weak" as ↵Rafael Espindola
llvm-gcc does, but are more strict on what uses of weakref we accept. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96992 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-23Unconditionally support block introspection data in a new field at the endBlaine Garst
of the block descriptor field. This field is the ObjC style @encode signature of the implementation function, and was to this point conditionally provided in the block literal data structure. That provisional support is removed. Additionally, eliminate unused enumerations for the block literal flags field. The first shipping ABI unconditionally set (1<<29) but this bit is unused by the runtime, so the second ABI will unconditionally have (1<<30) set so that the runtime can in fact distinguish whether the additional data is present or not. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96989 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-23Dead emit dead store warnings when assigning nil to an ObjC objectTed Kremenek
pointer (for defensive programming). This matches the behavior with assigning NULL to a regular pointer. Fixes <rdar://problem/7631278>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96985 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-23When comparing two calling conventions after redeclaring a function, compareCharles Davis
the canonical calling conventions instead of comparing the raw calling conventions directly. Fixes PR6361. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96895 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-23When a reference to a field of a struct/union/class is passed to theCharles Davis
__alignof__ operator, make sure to take into account the packed alignment of the struct/union/class itself. Matches GCC's behavior and fixes PR6362. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96884 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-23More fixes. Don't try to emit a virtual base vtable if the virtual base in ↵Anders Carlsson
question is a primary virtual base of some other base. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96881 91177308-0d34-0410-b5e6-96231b3b80d8

Remove a debug printf, and add the test case that now passes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96880 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-23Simplify the vcall offset calculation and make it give the correct answers ↵Anders Carlsson
:) My test case now has the right values but in the wrong order. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96877 91177308-0d34-0410-b5e6-96231b3b80d8

and into libAnalysis. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96872 91177308-0d34-0410-b5e6-96231b3b80d8

No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96847 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-23Perform two more constructor/destructor code-size optimizations:John McCall
1) emit base destructors as aliases to their unique base class destructors under some careful conditions. This is enabled for the same targets that can support complete-to-base aliases, i.e. not darwin. 2) Emit non-variadic complete constructors for classes with no virtual bases as calls to the base constructor. This is enabled on all targets and in theory can trigger in situations that the alias optimization can't (mostly involving virtual bases, mostly not yet supported). These are bundled together because I didn't think it worthwhile to split them, not because they really need to be. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96842 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-23Implement crazy destructor name lookup semantics differently inDouglas Gregor
C++98/03 and C++0x, since the '0x semantics break valid C++98/03 code. This new mess is tracked by core issue 399, which is still unresolved. Fixes PR6358 and PR6359. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96836 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-21Eliminate the default arguments to ASTContext::getFunctionType(),Douglas Gregor
fixing up a few callers that thought they were propagating NoReturn information but were in fact saying something about exception specifications. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96766 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-21Implement support for parsing pseudo-destructor expression with a ↵Douglas Gregor
nested-name-specifier, e.g., typedef int Int; int *p; p->Int::~Int(); This weakens the invariant that the only types in nested-name-specifiers are tag types (restricted to class types in C++98/03). However, we weaken this invariant as little as possible, accepting arbitrary types in nested-name-specifiers only when we're in a member access expression that looks like a pseudo-destructor expression. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96743 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-21A constructor template cannot be used to copy to an object of the same class ↵Douglas Gregor
type (per C++ [class.copy]p3). Make sure that includes copies that involve a derived-to-base conversion. Fixes PR6141. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96742 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-21Implement AST import for C++ member functions, including constructors, ↵Douglas Gregor
destructors, and conversions. Unfortunately, this cannot be tested yet, since we don't have C++ PCH support. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96741 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-21Commiting a revert from dgregor of a bit of destructor logic until we canChandler Carruth
figure out how not to break lots of code using this. See PR6358 and PR6359 for motivating examples. FIXME's left in the code and the test. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96733 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-21Make Decl::isOutOfLine() virtual, and use that to determine when definitionsChandler Carruth
are for out of line declarations more easily. This simplifies the logic and handles the case of out-of-line class definitions correctly. Fixes PR6107. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96729 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-21Clang really intends to reject attribute 'warn_unused_result' on Objective-C ↵Ted Kremenek
