required modifying a few tests that specifically use note include stacks
to check the source manager's view of include stacks. I've simply added
the flag to these tests for now, they may have to be more substantially
changed if we decide to remove support for note include stacks
altogether.
Also, add a test for include stacks on notes that was supposed to go in
with the previous commit.

These stacks are often less important than those on primary diagnostics.
As the number of notes grows, this becomes increasingly important. The
include stack printing is clever and doesn't print stacks for adjacent
diagnostics from the same file, but when a note is in between a sequence
of errors in a header file, and the notes all refer to some other file,
we end up getting a worst-case ping-pong of include stacks that take up
a great deal of vertical space.
Still, for now, the default behavior isn't changed. We can evaluate user
feedback with the flag.
Patch by Richard Trieu, a couple of style tweaks from me.

line options, instead of leveraging the blanket -mllvm option.
- This allows using the frontend itself without requiring the backend have
those options available (i.e., if the target wasn't built).

This change requires making a bunch of fundamental Clang structures (optionally) reference counted to allow correct
ownership semantics of these objects (e.g., ASTContext) to play out between an active ASTUnit and CompilerInstance
object.

add support for the OpenCL __private, __local, __constant and
__global address spaces, as well as the __read_only, _read_write and
__write_only image access specifiers. Patch originally by ARM;
language-specific address space support by myself.

Issue this as an IR-gen error; it's not really worthwhile doing this
"right", i.e. in Sema, because IR gen knows a lot of tricks beyond
what the constant evaluator knows.

should report the original file name for contents of files that were overriden by other files,
otherwise it should report the name of the new file. Default is true.
Also add similar field in PreprocessorOptions and pass similar parameter in ASTUnit::LoadFromCommandLine.

too low-level to actually be useful but is just interesting enough for
people to try to use it (which won't actually work beyond toy examples).
To bring back the AST printer, it needs to be:
- Complete, covering all of C/C++/Objective-C
- Documented, with appropriate Schema against which we can validate
the output
- Designed for C/C++/Objective-C, not Clang's specific ASTs
- Stable across Clang versions
- Well-tested

Allow remapping a file by specifying another filename whose contents should be loaded if the original
file gets loaded. This allows to override files without having to create & load buffers in advance.

The previous name was inaccurate as this token in fact appears at
the end of every preprocessing directive, not just macro definitions.
No functionality change, except for a diagnostic tweak.

way it keeps track of namespaces. Previously, we would map from the
namespace alias to its underlying namespace when building a
nested-name-specifier, losing source information in the process.

It works like -isystem and the search path keeps -isystem and
-cxx-isystem in order relative to each other. -cxx-isystem is only used
for C++ sources though. Drop the existing -cxx-system-include option for
cc1 as it is now redundant.

enumeration type, prioritize the enumeration constants and don't
provide completions for any other expressions. Fixes <rdar://problem/7283668>.

This removes the final dependency edge from any lib outside of CodeGen
to core. As a result we can, and do, trim the dependency on core
from libclang, PrintFunctionNames, the unit tests and c-index-test.
While at it, review and trim other unneeded dependencies.

code-completion results accessed via libclang, to extend the lifetime
of the allocator used for cached global code-completion results at
least until these completion results are destroyed. Fixes

completions. We now compute a hash of the names of all top-level
declarations and macro definitions, and invalidate the cache when the
hash value changes.

Store in PCH the directory that the PCH was originally created in.
If a header file is not found at the path that we expect it to be and the PCH file
was moved from its original location, try to resolve the file by assuming that
header+PCH were moved together and the header is in the same place relative to the PCH.

-Checkers will be defined in the tablegen file 'Checkers.td'.
-Apart from checkers, we can define checker "packages" that will contain a collection of checkers.
-Checkers can be enabled with -analyzer-checker=<name> and disabled with -analyzer-disable-checker=<name> e.g:
Enable checkers from 'cocoa' and 'corefoundation' packages except the self-initialization checker:
-analyzer-checker=cocoa -analyzer-checker=corefoundation -analyzer-disable-checker=cocoa.SelfInit
-Introduces CheckerManager and CheckerProvider. CheckerProviders get the set of checker names to enable/disable and
register them with the CheckerManager which will be the entry point for all checker-related functionality.
Currently only the self-initialization checker takes advantage of the new mechanism.

The optimization involves eagerly pruning ExplodedNodes from the ExplodedGraph that contain
practically no difference between the predecessor and successor nodes. For example, if
the state is different between a predecessor and a node, the node is left in. Only for
the 'environment' component of the state do we not care if the ExplodedNodes are different.
This paves the way for future optimizations where we can reclaim the environment objects.

overridden via remapping. Thus, when we create a "virtual" file in the
file manager, we still stat() the real file that lives behind it so
that we can provide proper uniquing based on inodes. This helps keep
the file manager much more consistent.
To take advantage of this when reparsing files in libclang, we disable
the use of the stat() cache when reparsing or performing code
completion, since the stat() cache is very likely to be out of date in
this use case.

the atomic writes option, since the intent is that this option be set for an
entire build, which may have any number of compiler instances writing to the
same output file.

- Aside from being generally cleaner, this also allows -H to work correctly in
modes other than standard preprocessing (e.g., -c, -MM, etc.)

BumpPtrAllocator, rather than manually new/delete'ing them. This
optimization also allows us to avoid allocating memory for and copying
constant strings (e.g., "return", "class").
This also required embedding the priority and availability of results
within the code completion string, to avoid extra memory allocation
within libclang.

FileManager.cpp: Allow virtual files in nonexistent directories.
FileManager.cpp: Close FileDescriptor for virtual files that correspond to actual files.
FileManager.cpp: Enable virtual files to be created even for files that were flagged as NON_EXISTENT_FILE, e.g. by a prior (unsuccessful) addFile().
ASTReader.cpp: Read a PCH even if the original source files cannot be found.
Add a test for reading a PCH of a file that has been removed and diagnostics referencing that file.
