location into a TemplateSpecializationTypeLoc. These were found using
a hand-written program to inspect every source location in
TemplateSpecializationTypeLocs and Valgrind. I don't know of any way to
test them in Clang's existing test suite sadly.

Example code that triggers the ElaboratedType case:
  template <typename T> struct X1 {
    template <typename U> struct X1_1 {
      int x;
    };
  };

  template <typename T, typename U> struct X2 {
    typename X1<T>::template X1_1<U> B;
  };

  X2<char, int> x2;

The other fix was simply spotted by inspection. I audited all constructions of
[Dependent]TemplateSpecializationTypeLocs in TreeTransform.h, and the rest set
the TemplateNameLoc properly.

the array alignment to the array access.
 - This is more or less the best we can do without having alignment present in
   the type system, but is a long way from truly matching how GCC handles this.

__block block declaration. //rdar://9204669

llvm-svn: 128682

Note this can potentially be enhanced to detect if the __block variable
is actually written by the block, or only when the block "escapes" or
is actually used, but that requires more analysis than it is probably worth
for this simple check.

Add security syntax checker for strcpy() which causes the Static Analyzer to generate a warning any time the strcpy() function is used with a note suggesting to use a function which provides bounded buffers. 

llvm-svn: 128679

Models mempcpy() so that if length is NULL the destination pointer is returned. Otherwise, the source and destination are confirmed not to be NULL and not overlapping. Finally the copy is validated to not cause a buffer overrun and the return value is bound to the address of the byte after the last byte copied.

Make ChainedIncludesSource an ExternalSemaSource, otherwise initialization of the ASTReader is incomplete, leading to errors like not realizing std::type_info is already defined.

llvm-svn: 128664

Tell the diagnostic client about starting and ending source files when automatically creating chained PCHs. This way, we don't get a crash whenever a diagnostic is emitted while processing the include.

__block object copy/dispose helpers for C++ objects with those for
different variables with completely different semantics simply because
they happen to both be no more aligned than a pointer.

Found by inspection.

Also, internalize most of the helper generation logic within CGBlocks.cpp,
and refactor it to fit my peculiar aesthetic sense.

Static analyzer: fix bug in handling of dynamic_cast<>.  The sink node wouldn't always be the final node, thus causing the state to continue propagating.  Instead,
recover some path-sensitivity by conjuring a symbol.

Teach static analyzer about the basics of handling new[].  We still don't simulate constructors, but at least the analyzer doesn't think the return value is uninitialized.
