The final graph contains a single root node, which is a parent of all externally available functions(and 'main'). As well as a list of Parentless/Unreachable functions, which are either truly unreachable or are unreachable due to our analyses imprecision.

The analyzer checkers debug.DumpCallGraph or debug.ViewGraph can be used to look at the produced graph.

Currently, the graph is not very precise, for example, it entirely skips edges resulted from ObjC method calls.

Basically the current design is:
-for an implementation method, show as overridden the interface method.
  This is not useful, and is inconsistent with the C++ side
-for an interface method, show as overridden the protocols methods (this is desirable)
  and the methods from the categories; methods from categories are not useful
  since they are considered the same method (same USR).
-If there is a protocol method or category method reported, it does not check the
  super class for overridden methods. This is really problematic since
  overridden methods from super class is what we want to give back.

Change clang_getOverriddenCursors to show as overridden any method in the class's
base class, its protocols, or its categories' protocols, that has the same
selector and is of the same kind (class or instance).
If no such method exists, the search continues to the class's superclass,
its protocols, and its categories, and so on. A method from an Objective-C
implementation is considered to override the same methods as its
corresponding method in the interface.

Add first linker pass (StubsPass) which looks for calls to shared library
symbols and replaces them with calls to a StubAtom.  On ELF system, a "stub"
is a PLT entry.  Added a simple test case.

Pass a Platform object to YAML reader and writer for converting fixup kinds 
between names and values.

Change output of Resolver to be a File object instead of a vector of Atoms.
Thus, passes operate on a File instead of just Atoms.

Rework how to walk through a File's Atoms. Now iterator based instead of 
a method that visits each atom.

PR12196: The module hash strings are not actually hashing the compiler version
string; the entire version string is being included in the hash.  Depending on
the module cache directory name, that can lead to failures where the path
names become too long.  As a temporary workaround, just remove the version
string from the hash.

code that will be relocated into another memory space.
Now when relocations are resolved, the address of
the relocation in the host memory (where the JIT is)
is passed separately from the address that the
relocation will be at in the target memory (where
the code will run).

Added a new makefile target to help us with Apple builds where the installhdrs
will copy the headers for the shared library. Prior to this fix, the install
headers directory would contain the unix style paths to all public header
files ("#include lldb/API/SBDefines.h") instead of the fixed up framework
header paths ("#include <LLDB/SBDefines.h>").

This fixes a build failure in webkit. Copying all elements shouldn't be
necessary, I'll look out for a better fix soon.

This fix really needed to happen as a previous fix I had submitted for
calculating symbol sizes made many symbols appear to have zero size since
the function that was calculating the symbol size was calling another function
that would cause the calculation to happen again. This resulted in some symbols
having zero size when they shouldn't. This could then cause infinite stack
traces and many other side affects.

Original commit message:
Use uint16_t to store InstrNameIndices in MCInstrInfo. Add asserts to protect 
all 16-bit string table offsets. Also make sure the string to offset table 
string is not larger than 65536 characters since larger string literals aren't 
portable.

We now just check if the new scattering would create non-positive dependences.
This is a lot faster than recalculating dependences (which is especially slow
on tiled code).

compilers. It seems that GCC 4.3 (and likely older) simply aren't going
to do SFINAE on non-type template parameters the way Clang and modern
GCCs do...

Now we detect the implicit conversion to an integer type, and then
blacklist classes, pointers, and floating point types. This seems to
work well enough, and I'm hopeful will return the bots to life.
