SBTarget::AddModule(const char *path,
const char *triple,
const char *uuid_cstr,
const char *symfile);
If "symfile" was filled in, it would cause us to not correctly add the module. Same goes for:
SBTarget::AddModule(SBModuleSpec ...)
Where you filled in the symfile.

This fix reduces the stack size of SymbolFileDWARF::ParseType(). It seems that clang is not very good at sharing locations on the stack with local variables in large functions that have many blocks and each variable gets unique locations. The reduction in size was done by:
1 - removing some large locals that were default constructed by not used
2 - Placing some larger local variables into std::unique_ptr<> to make them on the heap
3 - removing local variables there were large and being populated but not being used
4 - reducing the size of some typedefs to llvm::SmallVector<T, N> so that N wasn’t excessively large

This is a purely mechanical change explicitly casting any parameters for printf
style conversion. This cleans up the warnings emitted by gcc 4.8 on Linux.

This is a mechanical change addressing the various sign comparison warnings that
are identified by both clang and gcc. This helps cleanup some of the warning
spew that occurs during builds.

You can either provide the function name, or function body text.
Also propagate the compilation error up from where it is checked so we can report compilation errors.

On FreeBSD ptrace(PT_KILL) is used to terminate the traced process
(as if PT_CONTINUE had been used with SIGKILL as the signal to be
delivered), and is the desired behaviour for ProcessPOSIX::DoDestroy.
On Linux, after ptrace(PTRACE_KILL) the traced process still exists
and can be interrogated. It is only upon resume that it exits as though
it received SIGKILL.
As the Linux PTRACE_KILL behaviour is not used by LLDB, rename
BringProcessIntoLimbo to Kill, and change the implementation to simply
call kill() instead of using ptrace.
Thanks to Todd F for testing (Ubuntu 12.04, gcc 4.8.2).

Store the gpr data in a DataBufferHeap and use a DataExtractor to
extract register values with appropriate endianness. This avoids hard-
coding the register count, and with some further work would allow this
class to provide generic register context storage for any CPU.

For now I'm committing only the FreeBSD change, until the Linux change
(review D3159) is successfully tested.

For some reason, the libc++ vector<bool> data formatter was essentially a costly no-up, doing everything required of it, except actually generating the child values!
This restores its functionality

Since dosep.ty started invoking multiple tests in parallel, the FreeBSD
buildbot occasionally has a failure due to os.mkdir returning EEXIST.
Silently ignore that exception, but reraise any other.

These changes were written by Greg Clayton, Jim Ingham, Jason Molenda.
It builds cleanly against TOT llvm with xcodebuild. I updated the
cmake files by visual inspection but did not try a build. I haven't
built these sources on any non-Mac platforms - I don't think this
patch adds any code that requires darwin, but please let me know if
I missed something.
In debugserver, MachProcess.cpp and MachTask.cpp were renamed to
MachProcess.mm and MachTask.mm as they picked up some new Objective-C
code needed to launch processes when running on iOS.

to detach.
Also fix debugserver to send the OK AFTER it detaches to avoid the same race condition.

For small structs, the frame format now prints them as one-liners
This follows the same definition that frame variable does for deciding what a "small struct" is, and as such should be fairly consistent with the variable display in general

Add a GetFoundationVersion() to AppleObjCRuntime
This API is used to return and cache the major version of Foundation.framework, which is potentially a useful piece of data to key off of to enable or disable certain ObjC related behaviors (especially in data formatters)

This change makes significant improvements in the performance of
calculating a UUID within ObjectFileELF, and handles both running
processes and core files correctly. This does lazy evaluation of
UUID generation and caches the result when calculated.
Change by Piotr Rak.

Also added 'import sys' on some tests that are using non-standard
unittest2.skipUnless blocks with code that is intended to do things
that we have more specializes @* attributes for. These skip
conditions were failing to execute due to missing import, causing
darwin-only tests to run on Linux regardless. Will file a bug for
that separately.

When there was no process, the expression options were set to not ignore breakpoints. This causes debug info to be generated and causes errors when evaluating simple expressions.

"Running multithreaded with n threads (from LLDB_TEST_THREADS)" is
incorrect in the common case, because the thread count is now obtained
from a --threads option, or a default of multiprocessing.cpu_count().
I left the messages in for now as there are some intermittent issues
that happen while running tests multithreaded and it may help in
triaging those. We may wish to just remove them later on.

(lldb) b puts
(lldb) expr -g -i0 -- (int)puts("hello")
First we will stop at the entry point of the expression before it runs, then we can step over a few times and hit the breakpoint in "puts", then we can continue and finishing stepping and fininsh the expression.
Main features:
- New ObjectFileJIT class that can be easily created for JIT functions
- debug info can now be enabled when parsing expressions
- source for any function that is run throught the JIT is now saved in LLDB process specific temp directory and cleaned up on exit
- "expr -g --" allows you to single step through your expression function with source code

Previous check relied on -DLLDB_DISABLE_PYTHON which was not valid as
it is defined in the top level LLDB Makefile which is included after the check.
If this check is moved after the inclusion of top level Makefile then
BUILT_SOURCES is not properly handled. So I am using the scheme present
in the Host/Makefile.

PATH_MAX is defined if it is not already defined. A duplicate

This is a mechanical cleanup of unused functions. In the case where the
functions are referenced (in comment form), I've simply commented out the
functions. A second pass to clean that up is warranted.
The functions which are otherwise unused have been removed. Some of these were
introduced in the initial commit and not in use prior to that point!

TestPromptFormats appears as though it may be a useful unit test.
Unfortunately, there is no invocation mechanism in place right now. It is
unclear how to add a unit test for this scenario to the existing tests. It
would be ideal to remove this entirely, but I am hopeful that this can/will be
pulled out into a test still since it uses a user accessible interface.
