"desktop" - build all binaries with XPC
"desktop_no_xcp" - build all binaries with none of the XPC binaries
"ios" - build all binaries with special iOS install settings.
Bumped the Xcode project build version for lldb-118 and debugserver-169.

and also so we don't break them with our code changes.
The _only_ plug-ins that should be #ifdef'ed out and not compiled in LLDB
are those that only work when running natively on the host system.
This fixed bot the PlatformLinux and PlatformFreeBSD build breakages that
were due to ModuleSpec changes.

so that we don't break it with code changes.
After doing this I was able to fix the POSIX-DYLD plug-in so that it builds
after recent ModuleSpec changes.

Added a dedicated platform for the iOS simulator. This helps us to find the
correct files for a simulator binary before running and helps us select the
right arch (i386 only) for files when we load them.

is not available (LLDB_DISABLE_PYTHON is defined).
Change build-swig-Python.sh to emit an empty LLDBPythonWrap.cpp file if
this build is LLDB_DISABLE_PYTHON.
Change the "Copy to Xcode.app" shell script phase in the lldb.xcodeproj
to only do this copying for Mac native builds.

New public API for handling formatters: creating, deleting, modifying categories, and formatters, and managing type/formatter association.
This provides SB classes for each of the main object types involved in providing formatter support:
SBTypeCategory
SBTypeFilter
SBTypeFormat
SBTypeSummary
SBTypeSynthetic
plus, an SBTypeNameSpecifier class that is used on the public API layer to abstract the notion that formatters can be applied to plain type-names as well as to regular expressions
For naming consistency, this patch also renames a lot of formatters-related classes.
Plus, the changes in how flags are handled that started with summaries is now extended to other classes as well. A new enum (lldb::eTypeOption) is meant to support this on the public side.
The patch also adds several new calls to the formatter infrastructure that are used to implement by-index accessing and several other design changes required to accommodate the new API layer.
An architectural change is introduced in that backing objects for formatters now become writable. On the public API layer, CoW is implemented to prevent unwanted propagation of changes.
Lastly, there are some modifications in how the "default" category is constructed and managed in relation to other categories.

user space programs. The core file support is implemented by making a process
plug-in that will dress up the threads and stack frames by using the core file
memory.
Added many default implementations for the lldb_private::Process functions so
that plug-ins like the ProcessMachCore don't need to override many many
functions only to have to return an error.
Added new virtual functions to the ObjectFile class for extracting the frozen
thread states that might be stored in object files. The default implementations
return no thread information, but any platforms that support core files that
contain frozen thread states (like mach-o) can make a module using the core
file and then extract the information. The object files can enumerate the
threads and also provide the register state for each thread. Since each object
file knows how the thread registers are stored, they are responsible for
creating a suitable register context that can be used by the core file threads.
Changed the process CreateInstace callbacks to return a shared pointer and
to also take an "const FileSpec *core_file" parameter to allow for core file
support. This will also allow for lldb_private::Process subclasses to be made
that could load crash logs. This should be possible on darwin where the crash
logs contain all of the stack frames for all of the threads, yet the crash
logs only contain the registers for the crashed thrad. It should also allow
some variables to be viewed for the thread that crashed.

all RTTI types, and since we don't use RTTI anymore since clang and llvm don't
we don't really need this header file. All shared pointer definitions have
been moved into "lldb-forward.h".
Defined std::tr1::weak_ptr definitions for all of the types that inherit from
enable_shared_from_this() in "lldb-forward.h" in preparation for thread
hardening our public API.
The first in the thread hardening check-ins. First we start with SBThread.
We have issues in our lldb::SB API right now where if you have one object
that is being used by two threads we have a race condition. Consider the
following code:
1 int
2 SBThread::SomeFunction()
3 {
4 int result = -1;
5 if (m_opaque_sp)
6 {
7 result = m_opaque_sp->DoSomething();
8 }
9 return result;
10 }
And now this happens:
Thread 1 enters any SBThread function and checks its m_opaque_sp and is about
to execute the code on line 7 but hasn't yet
Thread 2 gets to run and class sb_thread.Clear() which calls m_opaque_sp.clear()
and clears the contents of the shared pointer member
Thread 1 now crashes when it resumes.
The solution is to use std::tr1::weak_ptr. Now the SBThread class contains a
lldb::ThreadWP (weak pointer to our lldb_private::Thread class) and this
function would look like:
1 int
2 SBThread::SomeFunction()
3 {
4 int result = -1;
5 ThreadSP thread_sp(m_opaque_wp.lock());
6 if (thread_sp)
7 {
8 result = m_opaque_sp->DoSomething();
9 }
10 return result;
11 }
Now we have a solid thread safe API where we get a local copy of our thread
shared pointer from our weak_ptr and then we are guaranteed it can't go away
during our function.
So lldb::SBThread has been thread hardened, more checkins to follow shortly.

Modified the Xcode project to not strip liblldb-core.a for BuildAndIntegration builds
and to correctly strip only debug symbols from the command line binaries.

PlatformDarwin.cpp -- call it from both PlatformRemoteiOS.cpp
and the native process PlatformDarwin.cpp when running on an arm
system.
Bump lldb version number to 94.

for all our external AST sources that lets us associate
arbitrary flags with the types we put into the AST
contexts. Also added an API on ClangASTContext that
allows access to these flags given only an ASTContext
and a type.
Because we don't have access to RTTI, and because at
some point in the future we might encounter external
AST sources that we didn't make (so they don't subclass
ClangExternalASTSourceCommon) I added a magic number
that we check before doing anything else, so that we
can catch that problem as soon as it appears.

to find Objective-C class types by looking in the
symbol tables for the individual object files.
I did this as follows:
- I added code to SymbolFileSymtab that vends
Clang types for symbols matching the pattern
"_OBJC_CLASS_$_NSMyClassName," making them
appear as Objective-C classes. This only occurs
in modules that do not have debug information,
since otherwise SymbolFileDWARF would be in
charge of looking up types.
- I made a new SymbolVendor subclass for the
Apple Objective-C runtime that is in charge of
making global lookups of Objective-C types. It
currently just sends out type lookup requests to
the appropriate SymbolFiles, but in the future we
will probably extend it to query the runtime more
completely.
I also modified a testcase whose behavior is changed
by the fact that we now actually return an Objective-C
type for __NSCFString.

C++ vtables, fixing a record layout problem in the
expression parser.
Also fixed various problems with the generation
and unpacking of llvm.zip given our new better
handling of multiple architectures in the LLVM
build.
(And added a log message that will hopefully catch
record layout problems in the future.)

we often nuke our "build" folder so we can do clean builds. This way if you
are building your own LLVM you won't have to rebuild LLVM when you do remove
your build folder. The new location for the LLVM build is:
lldb/llvm-build
