This checkin adds the capability for LLDB to load plugins from external dylibs that can provide new commands
It exports an SBCommand class from the public API layer, and a new SBCommandPluginInterface
There is a minimal load-only plugin manager built into the debugger, which can be accessed via Debugger::LoadPlugin.
Plugins are loaded from two locations at debugger startup (LLDB.framework/Resources/PlugIns and ~/Library/Application Support/LLDB/PlugIns) and more can be (re)loaded via the "plugin load" command
For an example of how to make a plugin, refer to the fooplugin.cpp file in examples/plugins/commands
Caveats:
Currently, the new API objects and features are not exposed via Python.
The new commands can only be "parsed" (i.e. not raw) and get their command line via a char** parameter (we do not expose our internal Args object)
There is no unloading feature, which can potentially lead to leaks if you overwrite the commands by reloading the same or different plugins
There is no API exposed for option parsing, which means you may need to use getopt or roll-your-own

We can now do:
Specify a path to a debug symbols file:
(lldb) add-dsym <path-to-dsym>
Go and download the dSYM file for the "libunc.dylib" module in your target:
(lldb) add-dsym --shlib libunc.dylib
Go and download the dSYM given a UUID:
(lldb) add-dsym --uuid <UUID>
Go and download the dSYM file for the current frame:
(lldb) add-dsym --frame

which builds a Debug+Asserts build of Clang and
links LLDB against it. The Debug configuration
builds Clang with Release+Asserts, for faster
linking and smaller memory footprint when debugging
the build LLDB.

top-of-tree. Removed all local patches and llvm.zip.
The intent is that fron now on top-of-tree will
always build against LLVM/Clang top-of-tree, and
that problems building will be resolved as they
occur. Stable release branches of LLDB can be
constructed as needed and linked to specific release
branches of LLVM/Clang.

This feature allows us to group test cases into logical groups (categories), and to only run a subset of test cases based on these categories.
Each test-case can have a new method getCategories(self): which returns a list of strings that are the categories to which the test case belongs.
If a test-case does not provide its own categories, we will look for categories in the class that contains the test case.
If that fails too, the default implementation looks for a .category file, which contains a comma separated list of strings.
The test suite will recurse look for .categories up until the top level directory (which we guarantee will have an empty .category file).
The driver dotest.py has a new --category <foo> option, which can be repeated, and specifies which categories of tests you want to run.
(example: ./dotest.py --category objc --category expression)
All tests that do not belong to any specified category will be skipped. Other filtering options still exist and should not interfere with category filtering.
A few tests have been categorized. Feel free to categorize others, and to suggest new categories that we could want to use.
All categories need to be validly defined in dotest.py, or the test suite will refuse to run when you use them as arguments to --category.
In the end, failures will be reported on a per-category basis, as well as in the usual format.
This is the very first stage of this feature. Feel free to chime in with ideas for improvements!

where the descriptor took a pointer to an object and
expected the Initialize function to dereference that
pointer and extract the isa value. This caused one
of our tests to fail.

KDP -- now with rudimentary process control (continue only) and read + write registers (which means we can see stack frames) for x86_64, i386 and ARM.

not correctly store the contents of Objective-C
classes. This was due to a combination of
factors:
1) Types were only being completed if we were
looking inside them for specific ivars
(using FindExternalVisibleDeclsByName).
We now look the complete type up at every
FindExternalLexicalDecls.
2) Even if the types were completed properly,
ValueObjectConstResult overrode the type
of every ValueObject using the complete type
for its class from the debug information.
Superclasses of complete classes are not
guaranteed to be complete. Although "frame
variable" uses the debug information,
the expression parser does now piece together
complete types at every level (as described
in Bullet 1), so I provided a way for the
expression parser to prevent overriding.
3) Type sizes were being miscomputed by
ClangASTContext. It ignored the ISA pointer
and only counted fields. We now correctly
count the ISA in the size of an object.

We can now read the relevant data structures for
the method list, and use a callback mechanism to
report their details to the AppleObjCTypeVendor,
which constructs appropriate Clang types.
