Francois Pichet 00c7e6ceb1 Implement function template specialization at class scope extension in Microsoft mode. A new AST node is introduced: ClassScopeFunctionSpecialization. This node holds a FunctionDecl that is not yet specialized; then during the class template instantiation the ClassScopeFunctionSpecialization will spawn the actual function specialization.
Example:
template <class T>
class A {
public:
  template <class U> void f(U p) {  }
  template <> void f(int p) {  } // <== class scope specialization
};

This extension is necessary to parse MSVC standard C++ headers, MFC and ATL code.
BTW, with this feature in, clang can parse (-fsyntax-only) all the MSVC 2010 standard header files without any error.

NAKAMURA Takumi c77574a2e3 Fix "Uninitialized" warnings on g++-4.4.
In fact, they are false warnings but it seems g++-4.4 might be unable to know they must be false.

Bob Wilson 0d45f58cbb Reject -mkernel for i386/Darwin C++ code; fall back to llvm-gcc instead.
Since -mkernel implies -fapple-kext, this just extends the current behavior
for -fapple-kext to apply for -mkernel as well.  Radar 9933387.

Apparently we never added code to expand these pseudo instructions, and in

Bob Wilson 445c24f8f0 Move handling of vget_lane/vset_lane before the code that checks the type.
Unlike most of the other Neon intrinsics, these are not overloaded and do not
have the extra argument that specifies the vector type.  This has not been
fatal because the lane number operand is supposed to be an ICE and so that
value has harmlessly been used as the type identifier.  Radar 9901281.

Nick Lewycky 2be81acd77 Remove the last improper use of getGlobalContext() from LLVM.
This caused a race condition where a thread calls ~LLVMContextImpl which calls
Module::dropAllReferences which calls begin() on an empty ilist that would
create the sentinel, which racily accesses the global context.

This can not be fixed by locking inside createSentinel because the lock would
need to be shared with all users of the global context, including those that
reside outside LLVM's own code.

Jim Ingham 16e0c68627 Make ValueObject::SetValueFromCString work correctly.
Also change the SourceInitFile to look for .lldb-<APPNAME> and source that
preferentially if it exists.
Also made the breakpoint site report its address as well as its breakpoint number
when it gets hit and can't find any the associated locations (usually because the
breakpoint got disabled or deleted programmatically between the time it was hit
and reported.)
Changed ThreadPlanCallFunction to initialize the ivar m_func in the initializers of the
constructor, rather than waiting to initialize till later on in the function.
Fixed a bug where if you make an SBError and the ask it Success, it returns false.
Fixed ValueObject::ResolveValue so that it resolves a temporary value, rather than
overwriting the one in the value object.

Anna Zaks fdd0aca0a5 MacOSKeychainAPIChecker:
Report errors earlier: on checkDeadSymbols() and clear the state after the symbol we are tracking goes out of scope. 

Also, perform lazy error checking. Instead of forcing the paths to be split depending one the return value of the allocator, make the return symbol depend on the allocated data symbol, which prolongs its life span to the time when the allocated data symbol becomes dead.

Greg Clayton 7e9b1fd045 We were leaking a stack frame in StackFrameList in Thread.cpp which could
cause extra shared pointer references to one or more modules to be leaked.
This would cause many object files to stay around the life of LLDB, so after
a recompile and rexecution, we would keep adding more and more memory. After
fixing the leak, we found many cases where leaked stack frames were still
being used and causing crashes in the test suite. These are now all resolved.
