This change does the following:
* Remove test/c++/...
* Add gtest.
* Add gtest/unittest directory for unittesting individual classes.
* Add an initial Plugins/Process?linux/ThreadStateCoordinatorTest.cpp.
- currently failing a test (intentional).
- added a bare-bones ThreadStateCoordinator.cpp to Plugins/Process/Linux,
more soon. Just enough to prove out running gtest on Ubuntu and MacOSX.
* Added recursive make machinery so that doing a 'make' in gtest/ is
sufficient to kick off the existing test several directories down.
- Caveat - I currently short circuit from gtest/unittest/Makefile directly to
the one and only gtest/unittest/Plugins/Process/Linux directory. We'll need
to add the intervening layers. I haven't done this yet since to fix the
Xcode test failure correspondence, I may need to add a python layer which
might just handle the directory crawling.
* Added an Xcode project to the lldb workspace for gtest.
- Runs the recursive make system in gtest/Makefile.
- Default target is 'test'. test and clean are supported.
- Currently does not support test failure file/line correspondence.
Requires a bit of text transformation to hook that up.

Makes use of LLVM gtest support. This does *not* run as part of
the lldb test suite.
I'm using it to start testing some components that
I'll be adding to the inner guts of NativeThreadLinux to more
maintainably handle thread states and deferred thread state notification.
Runs with default Makefile target "test" using gmake within a given
test directory (currently only test/c++/native_process/thread_state_coordinator).
The Makefile.rules currently assume it is using the LLVM gtest. It works on
a canonical MacOSX dir structture (i.e. lldb, lldb/llvm, lldb/llvm/tools/clang).
It also works on Ubuntu assuming the standard dir layout of llvm, llvm/tools/clang,
llvm/tools/lldb. In this case, it expects a directory called build-debug parallel
to the llvm source dir. All directory assumptions can be overridden with
environment variables. See test/c++/make/Makefile.rules for details.
We'll want to make this smarter in the future, particularly around finding the LLVM build
output dir.

Changes include:
- fix it so you can select the "host" platform using "platform select host"
- change all callbacks that create platforms to returns shared pointers
- fix TestImageListMultiArchitecture.py to restore the "host" platform by running "platform select host"
- Add a new "PlatformSP Platform::Find(const ConstString &name)" method to get a cached platform
- cache platforms that are created and re-use them instead of always creating a new one

For the Objective-C case, we do not have a "function type" notion, so we actually end up wrapping the clang ObjCMethodDecl in the Impl object, and ask function-y questions of it
In general, you can always ask for return type, number of arguments, and type of each argument using the TypeMemberFunction layer - but in the C++ case, you can also acquire a Type object for the function itself, which instead you can't do in the Objective-C case

Also, in case they don't define any, change the default from "Run Python function <blah>" into "For more information run help <blah>"
The core issue here is that Python only allows one docstring per function, so we can't really attach both a short and a long help to the same command easily
There are alternatives but this is not a pressing enough concern to go through the motions quite yet

* Fixes the local stack variable return pointer usage in NativeThreadLinux::GetName().
* Changes NativeThreadProtocol::GetName() to return a std::string.
* Adds a unit test to verify thread names don't regress in the future. Currently only run on Linux since I know default thread names there.

* Sends a SIGSTOP to the process.
* Fixes busted SIGSTOP handling. Now builds a list of non-stopped
that we wait for the PTRACE group-stop for. When the final must-stop
tid gets its group stop, we propagate the process state change.
Only the signal receiving the notification of the pending SIGSTOP
is marked with the SIGSTOP signal. All the rest, if they weren't
already stopped, are marked as stopped with signal 0.
* Fixes a few broken tests.
* Marks the Linux test I added earlier as expect-pass (no longer XFAIL).

Adds the qThreadStopInfo RSP command for llgs and includes a test that

llgs Linux is no longer doing the translation to some gdb fixed signal
numbers. This change modifies the test method to take in the signo
expected for a segfault. The debugserver test uses the fixed gdb number,
and everything else uses signal.SIGSEGV for the platform.
Sidenote: I somehow did not see this reported in multicore tests.
I will need to verify that we aren't missing test failures in that
script. I need to verify why this wasn't more obvious with
test/dosep.py.

And likewise for qProcessInfo on Linux, but ensures cputype/cpusubtype is not defined. The
Apple case is the more important one, since we take a slightly different path to initialize
ProcessGDBRemote-related remote host/process info if triple is present.

This change:
* Modifies llgs to send triple instead of cputype and cpusubtype when not on Apple platforms in qProcessInfo.
* Modifies lldb's GDBRemoteCommunicationClient to handle the triple returned from qProcessInfo if given.
When given, it will prefer to use triple over cputype and cpusubtype.
* Adds gdb-remote protocol tests to verify that cputype and cpusubtype are specified on darwin, and that triple is specified on Linux.

I'm about to add some more qProcessInfo tests so I wanted to first pull them out

Many of the test executables use pthreads directly. This isn't
portable on Windows, so this patch converts these test to use
C++11 threads and mutexes. Since Windows' implementation of
std::thread classes throw and catch from header files, this patch
also disables exceptions when compiling with clang on Windows.

Previously, CMake was invoking the test runner and not specifying
what architecture to use when building test executables. The
Makefiles for the test executables then had logic to choose x64
by default. This doesn't work on Windows because the test compiler
would then try to link against the 64-bit MSVCRT and not find them
since only the 32-bit MSVCRT was in the path.
This patch addresses this by figuring out, at CMake time, whether
or not you are building LLDB with a 64 or 32-bit toolchain. Then,
it explicitly passes this value to the test runner, causing the
test runner to build tests whose architecture matches that of LLDB
itself. This can still be overridden by setting the CMake variable
LLDB_TEST_EXECUTABLE_ARCH=(x64|x86)
llvm-svn: 214443
This was causing core dumps on MacOSX and was not properly
cleaning up the state of the inferior before exiting.
The test was overriding def tearDown(), but failed to
call the base class after doing its own cleanup. This
essentially eliminated normal clean-up activity.
llvm-svn: 214138
Currently, the test runner makes the assumption that it will run
commands through /bin/sh. This is obviously not true on Windows,
so this patch abstracts this logic out somewhat. Instead of
having the caller build the command string himself, the caller
will now pass in argument list of the form [[a, b], [c, d], ...]
which will get converted into a string of the form a b; c d or
a b && c d, depending on the platform.

lldb -P, which outputs its python path, works by using Host-layer
facilities to get information about the loaded python module. This
Host functionality was unimplemented on Windows, so this patch
implements it. Additionally, it removes a pexpect dependency from
the test runner and uses an equivalent invocation of subprocess.

99% of this CL is simply moving calls to "import pexpect" to a more
narrow scope - i.e. the function that actually runs a particular
test. This way the test suite can run on Windows, which doesn't have
pexpect, and the individual tests that use pexpect can be disabled on
a platform-specific basis.
Additionally, this CL fixes a few other cases of non-portability.
Notably, using "ps" to get the command line, and os.uname() to
determine the architecture don't work on Windows. Finally, this
also adds a stubbed out builder_win32 module.
The full test suite runs correctly on Windows after this CL, although
there is still some work remaining on the C++ side to fix one-shot
script commands from LLDB (e.g. script print "foo"), which currently
deadlock.

This change adds a member to the base test case for gdb-remote that
indicates whether a stub makes two X stop notification reports on kill
commands. This is set to true for debugserver tests.
The test for killing an attached process after it's first stop notification
has been modified to look at that flag and add an extra X packet matcher
so the "unmatched packet warning" doesn't get emitted for the second X on
MacOSX with debugserver.
I also broke those tests out of the monolithic TestLldbGdbServer mega test
case and put it in its own, new TestGdbRemoteKill.py file and test case.
Tested:
Ubuntu 14.04 x86_64, clang-3.5 built lldb, no test failures.
MacOSX 10.9.4, Xcode 6.0 Beta 3 built lldb, no test failures.
llvm-svn: 213166
Fixed the test case to use a runtime function prototype that will be correct ([NSString stringWithCString: "new"]) instead of one that won't (expression str = [NSString stringWithFormat: @"%cew", 'N']). The runtime doesn't track vararg functions correctly so we can't reconstitute the function correctly.
Also fixed some expressions that used "str_id" whose type was "id" and do the necessary casting since "id" doesn't have any methods.
llvm-svn: 213113
Now that llgs supports communicating the 0-port choose-a-port
mechanism and can communicate that back to a caller via the
--named-pipe option (at parity with debugserver), we use this
mechanism to always start llgs and debugserver gdb-remote
protocol tests without needing to use some port arbitration
mechanism. This eliminates some potential intermittent failures vs. the
previous random port and collision-avoidance strategy used.

The --setsid (-S) option changes the session id for the lldb-gdbserver process.
This is used by tools such as lldb-platform and allows the user to prevent

lldb-gdbserver.

debug sessions simultaneously to expose race conditoin/locking
issues.
This directory has an inferior program, testprog.cpp that has a
couple of functions we can put breakpoints on.
It has a driver program, multi-process-driver.cpp, which links
against the LLDB solib and uses the SB APIs. It creates 50 pthreads,
creates a debugger on all of them, launches a debug session of the
inferior testprog, hits a couple breakpoints, walks the stack,
continues, etc., and then kills the inferior and ends the debug
session.
A pass is if all fifty debug sessions complete successfully
in the alloted time (~60 seconds).
We may need to tweak this one to work correctly on different
platforms/targets but I wanted to get it checked in to start.

On MacOSX, we need to adjust the way we clean up the crashlog dylib in deleteCrashInfoDylib().
Right now it is only geared to run one test at a time. For now I'm just skipping the delete.
I'll work with Apple on a fix that handles this. It seems to only cause one dylib total to
hang around that might otherwise have been deleted. Fixes MacOSX multiple tests running
at the same time. (I didn't hit this on Yosemite, might be an issue that only shows up
on Mavericks?)

This change modifies the way the multi-threaded test runner works.
It uses the Python multiprocessing library rather than the threading
library. Investigation showed that all MacOSX threads were waiting on
the global python lock when using the threading approach. Not sure
why that differed from the Linux/FreeBSD implementations.
The new approach uses the multiprocessing library's Pool class. It's
mildly cleaner than the other version, runs multithreaded on MacOSX,
and seems to have caused no performance regression on Linux. The
worker thread logic is simpler with the Pool managing the worker
processes.
This also includes a minor change to the test runner's python
lldb dir logic using the -P option. It now looks at the last line
of output rather than the first line. This covers part of the issue
of extra options validation logic getting spit out. The test runner
will now pick up the right python library directory. It does not
fix all the issues, though, as a ton of tests (50+ on Linux) are
failing due to unexpected output when running lldb.
