Summary:
Previously the add_test_categories would simply overwrite the current set of categories for a
method. This change makes the decorator truly "add" categories, by extending the current set of
categories instead of replacing it.
To do this, I have:
- replaced the getCategories() property on a method (which was itself a method), with a simple
list property "categories". This makes add_test_categories easier to implement, and test
categories isn't something which should change between calls anyway.
- rewritten the getCategoriesForTest function to merge method categories with the categories of
the test case. Previously, it would just use the method categories if they were present. I have
also greatly simplified this method. Originally, it would use a lot of introspection to enable
it being called on various types of objects. Based on my tests, it was only ever being called
on a test case. The new function uses much less introspection then the preivous one, so we
should easily catch any stray uses, if there are any, as they will generate exceptions now.

When multiple functions are found by name, lldb removes duplicate entries of
functions with the same type, so the first function in the symbol context list
is chosen, even if it isn't in scope. This patch uses the declaration context
of the execution context to select the function which is in scope.
This fixes cases like the following:
int func();
namespace ns {
int func();
void here() {
// Run to BP here and eval 'p func()';
// lldb used to find ::func(), now finds ns::func().
}
}

stl upper_bound method instead of lower_bound - we were
failing to find some cached data in the L1 cache resulting
in extra memory read packets while stepping.
The bug with the existing code looked like this:
If the L1 cache has 8 bytes at address 0x1000 and 8 bytes
at address 0x2000 and we are searching for 4 bytes at 0x2004,
the use of lower_bound would return the end() of the container
and so we would incorrectly treat the memory as uncached.
(the L1 cache is memory seeded from debugserver in the T aka
questionmark packet, where debugserver will send up the stack
memory that likely contains the caller's stack pointer and
frame pointer values.)

This will be used in a future change to support rerunning flakey tests
that hit a test result isue in a low-load, single worker test runner phase.
This is implemented as an additive-style event rather than being

only runs after the start_test event is created and sent. i.e.
LLDBTestResult.startTest() runs before the test method decorators run.

Adding the modules to the global module list eleminate issues in the
case when a module is unloaded from the target but some object (e.g.

up the case when we load, unload, load the same shared library because

The standard remote debugging workflow with gdb is to start the
application on the remote host under gdbserver (e.g.: gdbserver :5039
a.out) and then connect to it with gdb.
The same workflow is supported by debugserver/lldb-gdbserver with a very
similar syntax but to access all features of lldb we need to be
connected also to an lldb-platform instance running on the target.
Before this change this had to be done manually with starting a separate
lldb-platform on the target machine and then connecting to it with lldb
before connecting to the process.
This change modifies the behavior of "platform connect" with
automatically connecting to the process instance if it was started by
the remote platform. With this command replacing gdbserver in a gdb
based worflow is usually as simple as replacing the command to execute
gdbserver with executing lldb-platform.

This moves all the global variables into a separate module called
`configuration`. This has a number of advantages:
1. Configuration data is centrally maintained so it's easy to get
a high level overview of what configuration data the test suite
makes use of.
2. The method of sharing configuration data among different parts
of the test suite becomes standardized. Previously we would
put some things into the `lldb` module, some things into the
`lldbtest_config` module, and some things would not get shared.
Now everything is shared through one module and is available to
the entire test suite.
3. It opens the door to moving some of the initialization code into
the `configuration` module, simplifying the implementation of
`dotest.py`.
There are a few stragglers that didn't get converted over to using
the `configuration` module in this patch, because it would have grown
the size of the patch unnecessarily. This includes everything
currently in the `lldbtest_config` module, as well as the
`lldb.remote_platform` variable. We can address these in the future.

already does a decent amount of checking
- fixup test_state_after_expression: this was calling the wrong function by mistake. As now the
function actually tests something (which we know is broken), I needed to XFAIL it as well.
- replaces the sleep() with a proper wait-for-event functionality in parts which use async mode,
to stabilize the one function that actually tests something.

This is done by finding the types that are forward declarations that come from a module, and loading that module's debug info in a separate lldb_private::Module, and copying the type over into the current module using a ClangASTImporter object. ClangASTImporter objects are already used to copy types from on clang::ASTContext to another for expressions so the type copying code has been around for a while.
A new FindTypes variant was added to SymbolVendor and SymbolFile:
size_t
SymbolVendor::FindTypes (const std::vector<CompilerContext> &context, bool append, TypeMap& types);
size_t
SymbolVendor::FindTypes (const std::vector<CompilerContext> &context, bool append, TypeMap& types);
The CompilerContext is a way to represent the exact context of a type and pass it through an agnostic API boundary so that we can find that exact context elsewhere in another file. This was required here because we can have a module that has submodules, both of which have a "foo" type.
I am not able to add tests for this yet as we currently don't build our C/C++/ObjC binaries with the clang binary that we build. There are some driver issues where it can't find the header files for the C and C++ standard library which makes compiling these tests hard. We can't also guarantee that if we are building with clang that it supporst the exact format of -gmodule debugging that we are trying to test. We have had other versions of clang that had a different implementation of -gmodule debugging that we are no longer supporting, so we can't enable tests if we are building with clang without compiling something and looking at the structure of the DWARF that was generated to ensure that it is the format we can actually use.

Summary:
The following situation was occuring in TestAttachResume:
- we did a "continue" from a breakpoint (which involves a private start-stop to step over the
breakpoint)
- after receiving the stop-reply from the step-over, we issue a "detach" (which requires a
process interrupt)
- at this moment, the public state is "running", private state is "about-to-be-stopped" (the
stopped event was broadcast, but it was not received yet)
- StopForDestroyOrDetach (public thread) notes the public state is running, sends an interrupt
request to the private thread
- private thread gets the eBroadcastBitInterrupt (before the eStateStopped message), and asks the
process plugin to stop (via Halt())
- process plugin says it has nothing to do as the process is already stopped
- private thread shrugs and carries on. receives the stop event, restores the breakpoint and
resumes the process.
- after a while, the public thread times out and says it failed to stop the process
This patch does the following:
- splits Halt() into two functions, private and public, their usage depends on the context
- public Halt(): sends eBroadcastBitInterrupt to the private thread and waits for the Stop
event
- HaltPrivate(): asks the plugin to stop and makes a note that the halt was requested. When the
next stop event comes it sets the interrupt flag on it.
- removes HijackPrivateProcessEvents(), as the only user (old Halt()) has gone away
- removes the m_currently_handling_event hack, as the new Halt() does not need it
- adds a use_run_lock parameter to public Halt() and WaitForProcessToStop(). This was needed
because RunThreadPlan uses Halt() while holding the run lock and we don't want Halt() to take

This patch will clear bug 25194 - LLDB-Server Assertion raised when single stepping on MIPS. The problem was that while emulating instructions, old and new pc values would have garbage value in their upper 32 bits. Therefore checking if pc was changed (old_pc == new_pc) would always return false, because of which pc was not getting updated.
/* If we haven't changed the PC, change it here */
if (old_pc == new_pc)
{
new_pc += 4;
Context context;
return false;
}

This patch adds functionality for dumping allocations of struct elements. This involves:
+ Jitting the runtime for details on all the struct fields.
+ Finding the name of the struct type by looking for a global variable of the same type, which will have been reflected back to the java host code.
+ Using this struct type name to pass into expression evaluation for pretty printing the data for the dump command.

Summary:
This makes sure we do not attempt to send output over the gdb-remote protocol when the client is
not expecting it (i.e., after sending the stop-reply packet). Normally, this should not happen
(the process cannot generate output when it is stopped), but due to the fact that pty
communication is asynchronous in the linux kernel (llvm.org/pr25652), we may sometimes get this
output too late. Instead, we just hold the output, and send it next time we resume. This is not
ideal, but at least it makes sure we do not violate the remote protocol. Given that this happens
extremely rarely it's not worth trying to work around it with sleeps or something like that.
I also remove the m_stdio_communication_mutex, as all of LLGS is now single-threaded anyway.

We were trying to be super smart and find all the supported language
bindings. This led to us scanning the directory and treating all
subdirectories as language binding directories. This makes it
hard to add unrelated code in this folder.
Besides, we only support one at the moment - Python. And when new
ones are added it will be trivial to just add their names to a list.
So this patch gets stupider about how to look for language binding
subfolders. Just put them in a list, and use the list.
llvm-svn: 254078
This script really should not be assuming every subdirectory is
a language directory for swig generation. Using a hack to get
this working for now, but this should be solved once this script
is re-written similar to how prepare_bindings was.
llvm-svn: 254037
With this patch, the client will package up all the required
inputs into a compressed zip file, establish a connection to the
server, send the input to the server, and wait for the server to
send a response (in this case the response is just echoed back to
the client).
This gets the network communication in place, and in a subsequent
patch I will follow up with the code that actually runs swig on
the server and sends back the output instead of echoing back the
input.
llvm-svn: 254023
This version supports local generation only. It's intentionally
stupid, and does not support any kind of dependency checking.
If you run the script, it's going to call SWIG. While this is
a slow process, we are going to combine the use of the swig bot
with checked in static bindings, meaning that it won't be terribly
important to only regenerate the bindings when the input files
have actually changed.
A side benefit of this is that the implementation is drastically
simpler.
This is all experimental at the moment, but it duplicates a lot
of the logic currently found in prepare_bindings.py. There was
not a good way to reuse some of the logic without invasive changes
on that script, and since this script is still experimental, it
makes sense to just copy them over, and if / when this becomes
more mature, we can get rid of the other ones.

Also, in TargetList::CreateTargetInternal, check that a platform

adding it to the vector of platforms unconditionally; we can end up
crashing when we call a member function on it later.

-fms-compatibility-version defaults to VS 2013. When using
VS 2015, this will lead to compilation failures of the test
inferiors in the C++ standard library for language conformance
reasons.
The fix here is to simply pass -fms-compatibility-version=19.0 when
we detect that a VS 2015 compiler is present. Even though we're
actually using clang to do the compilation, clang uses this same
detection algorithm to determine the location of the standard
library. So this check is tantanmount to saying "If clang is going
to find MSVC 2015's standard library, then pass 19.0 for
-fms-compatibility-version.

This patch fixes two issues:
1) Popen needs to be used with universal_newlines=True by default.
This elicits automatic decoding from bytes -> string in Py3,
and has no negative effects in other Py versions.
2) The swig typemaps for converting between string and (char*, int)
did not work correctly when the length of the string was 0,
indicating an error. In this case we would try to construct a
string from uninitialized data.
3) Ironically, the bug mentioned in #2 led to a test passing on
Windows that was actually broken, because the test was written
such that the assertion was never even getting checked, so it
passed by default. So we additionally fix this test to also
fail if the method errors. By fixing this test it's now broken
on Windows, so we also xfail it.

This change does not introduce static bindings. It is simply using
the pylinted cleaned up code in prepare_bindings.py.
If this breaks anyting, I'll revert immediately and figure out what
needs to be addressed. I'm looking to wrap up
the cleanup aspect of the code change (pylinted, removal of code that
implements existing python stdlib code, fixes for Xcode adoption, etc.).

Added a new flag, --allow-static-binding. When specified,
if (and only if) the swig binary cannot be found, then the
LLDBWrapPython.cpp and lldb.py from the
scripts/Python/{static-binding-dir} are copied into the place where
swig would have generated them.
{static-binding-dir} defaults to static-binding, and can be
overridden with the --static-binding-dir command line argument.
The static bindings checked in are from r253424.

Summary: The self.getArchitecture() returns the architecture based on the value of -A flag passed to dotest.py script.
There are many possible values for MIPS to this option (like mips32r2, mips32r6, mips64, mips64r2,.... ).
This patch uses re.match(mips,arch) to check if architecture string starts with mips.

This is only used by Xcode at the moment. It replaces the
buildSwigWrapperClasses.py and related per-script-language
scripts. It also fixes a couple bugs in those w/r/t Xcode
usage:
* the presence of the GCC_PREPROCESSOR_DEFINITIONS env var
should not be short-circuiting generation of the language
binding; rather, only if LLDB_DISABLE_PYTHON is present
within that environment variable.
* some logic around what to do when building in "non-Makefile"
mode. I've switched the handling of that to be on a
"--framework" flag - if specified, we build an OS X-style
framework; otherwise, we go with non.
Putting this up now only attached to the Xcode build so
others can look at it but not be affected by it yet.
After this, I'll tackle the finalizer, along with trying
it locally on Linux.

Python to assert when iterating over a generator. This patch
