There was no way to find out what's wrong if SBProcess SBTarget::LoadCore(const char *core_file) failed.
Additionally, the implementation was unconditionally setting sb_process, so it wasn't even possible to check if the return SBProcess is valid.
This change adds a new overload which surfaces the errors and also returns a valid SBProcess only if the core load succeeds:
SBProcess SBTarget::LoadCore(const char *core_file, SBError &error);

Summary:
This adds a SBDebugger::GetBuildConfiguration static function, which
returns a SBStructuredData describing the the build parameters of
liblldb. Right now, it just contains one entry: whether we were built
with XML support.
I use the new functionality to skip a test which requires XML support,
but concievably the new function could be useful to other liblldb
clients as well (making sure the library supports the feature they are
about to use).

Summary:
r316368 broke this build when it introduced a reference to a pthread
function to the Utility module. This caused cmake to generate an
incorrect link line (wrong order of libs) because it did not see the
dependency from Utility to the system libraries. Instead these libraries
were being manually added to each final target.
This changes moves the dependency management from the individual targets
to the lldbUtility module, which is consistent with how llvm does it.
The final targets will pick up these libraries as they will be a part of
the link interface of the module.
Technically, some of these dependencies could go into the host module,
as that's where most of the os-specific code is, but I did not try to
investigate which ones.

The core of this change is the new CommandInterpreter::m_command_state,
which models the state transitions for interactive commands, including
an "interrupted" state transition.
In general, command interruption requires cooperation from the code
executing the command, which needs to poll for interruption requests
through CommandInterpreter::WasInterrupted().
CommandInterpreter::PrintCommandOutput() implements an optionally
interruptible printing of the command output, which for large outputs
was likely the longest blocking part.

When introduced, breakpoint names were just tags that you could
apply to breakpoints that would allow you to refer to a breakpoint
when you couldn't capture the ID, or to refer to a collection of
breakpoints.
This change makes the names independent holders of breakpoint options
that you can then apply to breakpoints when you add the name to the
breakpoint. It adds the "breakpoint name configure" command to set
up or reconfigure breakpoint names. There is also full support for
then in the SB API, including a new SBBreakpointName class.
The connection between the name and the breakpoints
sharing the name remains live, so if you reconfigure the name, all the
breakpoint options all change as well. This allows a quick way
to share complex breakpoint behavior among a bunch of breakpoints, and
a convenient way to iterate on the set.
You can also create a name from a breakpoint, allowing a quick way
to copy options from one breakpoint to another.
I also added the ability to make hidden and delete/disable protected
names. When applied to a breakpoint, you will only be able to list,
delete or disable that breakpoint if you refer to it explicitly by ID.
This feature will allow GUI's that need to use breakpoints for their
own purposes to keep their breakpoints from getting accidentally
disabled or deleted.

You can get a breakpoint to auto-continue by adding "continue"
as a command, but that has the disadvantage that if you hit two
breakpoints simultaneously, the continue will force the process
to continue, and maybe even forstalling the commands on the other.
The auto-continue flag means the breakpoints can negotiate about
whether to stop.
Writing tests, I wanted to supply some commands when I made the
breakpoints, so I also added that ability.

When an option was set at on a location, I was just copying the whole option set
to the location, and letting it shadow the breakpoint options. That was wrong since
it meant changes to unrelated options on the breakpoint would no longer take on this
location. I added a mask of set options and use that for option propagation.
I also added a "location" property to breakpoints, and added SBBreakpointLocation.{G,S}etCommandLineCommands
since I wanted to use them to write some more test cases.

The simple module import logic was not sufficient for our distribution
model of lldb, which is without the _lldb.pyd file (normally that would
be a symlink to the shared library, but symlinks are not really a thing
on windows).
With the older swigs it worked (loading of the python scripting
machinery from within lldb) because the normal swig import logic
contained a last-ditch import of a global module _lldb (which is defined
when you run python from lldb). Add back the last-ditch import to our
custom import logic as well.

Summary:
This patch introduces new SB APIs for tracing support
inside LLDB. The idea is to gather trace data from
LLDB and provide it through this APIs to external
tools integrating with LLDB. These tools will be
responsible for interpreting and presenting the
trace data to their users.
The patch implements the following new SB APIs ->
-> StartTrace - starts tracing with given parameters
-> StopTrace - stops tracing.
-> GetTraceData - read the trace data .
-> GetMetaData - read the meta data assosciated with the trace.
-> GetTraceConfig - read the trace configuration
Tracing is associated with a user_id that is returned
by the StartTrace API and this id needs to be used
for accessing the trace data and also Stopping
the trace. The user_id itself may map to tracing
the complete process or just an individual thread.
The APIs require an additional thread parameter
when the user of these APIs wishes to perform
thread specific manipulations on the tracing instances.
The patch also includes the corresponding
python wrappers for the C++ based APIs.

We currently display a list of all minimal cycles, but it's
useful to be able to see the big picture impact of these cycles
by merging them all together into groups of interconnected
components.
Because the cycle discovery algorithm only considers "minimal"
cycles, it discards all information for dependencies which are
not considered part of the minimal cycle. So all we know is that
the components of each island definitely all depend on each other
but it's still possible that there are hidden dependencies due
to transitive includes.
The cycle list should still be the authoritative reference for
deciding where the easiest places to break cycles are, though.

When passing --discover-cycles and --show-counts, it displays
the number of dependencies between each hop of the cycle,
and sorts by the sum. Dependencies at the top of the list
should be the easiest to break.
llvm-svn: 298455
This analyzes the dependency graph and computes all minimal
cycles. Equivalent cycles that differ only by rotation are
excluded, as are cycles that are "super-cycles" of other
smaller cycles. For example, if we discover the cycle
A -> C -> A, and then later A -> B -> C -> D -> A, this latter
cycle is not considered. Thus, it is possible that after
eliminating some cycles, new ones will appear. However,
this is the only way to make the algorithm terminate in
a reasonable amount of time.
