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.

Some repos are not git repos, so git is expected
to fail. These errors should not go to stderr,
because Xcode interprets them as failures.

LLDB has many branches in a variety of repositories.
The build-script.py file is subtly different for each set.
This is unnecessary and causes merge headaches.
This patch makes build-llvm.py consult a directory full
of .json files, each one of which matches a particular
branch using a regular expression.
This update to the patch introduces a FALLBACK file
whose contents take precedence if the current branch
could not be identified. If the current branch could be
identified, FALLBACK is updated, allowing the user to
e.g. cut branches off of known branches and still have
the automatic checkout mechanism work.
It also documents all of this.

Summary:
The current version of LLDB installs six.py into global python library directory. This approach produces conflicts downstream with distribution's py-six copy.
Introduce new configure option LLDB_USE_SYSTEM_SIX (disabled by default). Once specified as TRUE, six.py won't be installed to Python's directory.
Add new option in finishSwigWrapperClasses.py, namely --useSystemSix.

A combination of broken escaping in CMake and in the python swig
generation scripts meant that the swig generation step would fail
whenever there were spaces or special characters in parameters passed to
swig.
The fix for this in CMakeLists is to use the VERBATIM option on all
COMMAND-based custom builders relying on CMake to properly escape each
argument in the generated file.
Within the python swig scripts, the fix is to call subprocess.Popen with
a list of raw argument strings rather than ones that are incorrectly
manually escaped, then passed to a shell subprocess via
subprocess.Popen(' '.join(params)). This also prevents nasty things
happening such as accidental command-injection.
This allows us to have the swig / python executables in paths containing
special chars and spaces, (or on shared storage on Win32, e.g
\\some\path or C:\Program Files\swig\swig.exe).

LLDB needs some minor changes to adopt PrettyStackTrace after https://reviews.llvm.org/D27683.
We remove our own SetCrashDescription() function and use LLVM-provided RAII objects instead.
We also make sure LLDB doesn't define __crashtracer_info__ which would collide with LLVM's definition.

Rationale:
scripts/Python/modules: android is excluded at a higher level, so no point in
checking here
tools/lldb-mi: lldb-mi builds fine (with some cosmetic tweaks) on android, and
there is no reason it shouldn't.
tools/lldb-server: LLDB_DISABLE_LIBEDIT/CURSES already take the platform into
account, so there is no point in checking again.
I am reasonably confident this should not break the build on any platform, but
I'll keep an eye out on the bots.

I added a "thread-stop-format" to distinguish between the form
that is just the thread info (since the stop printing immediately prints
the frame info) and one with more frame 0 info - which is useful for
"thread list" and the like.
I also added a frame.no-debug boolean to the format entities so you can
print frame information differently between frames with source info and those
without.
This closes https://reviews.llvm.org/D26383.

Summary: This tool is only built on Darwin, and the name darwin-debug matches the Xcode project. We should have this in sync unless there is a good reason not to.

Summary:
If Python is installed to a location that contains spaces
(e.g. "C:\Program Files\Python3") then the build fails while attempting
to run the modify-python-lldb.py script because the path to the Python
executable is not double-quoted before being passed to the shell. The
fix consists of letting Python handle the formatting of the command
line, since subprocess.Popen() is perfectly capable of handling paths
containing spaces if it's given the command and arguments as a list
instead of a single pre-formatted string.
