Summary:
r284830 added a summary provider for unique_ptr in libstdc++, whose value printed
the value of the pointee. This is a bit unintuitive as it becomes unobvious that
the value actually is a pointer, and we lose the way to actually obtain the
pointer value.
Change that to print the pointer value instead. The pointee value can still be
obtained through the synthetic children.

*** to conform to clang-format’s LLVM style. This kind of mass change has
*** two obvious implications:
Firstly, merging this particular commit into a downstream fork may be a huge
effort. Alternatively, it may be worth merging all changes up to this commit,
performing the same reformatting operation locally, and then discarding the
merge for this particular commit. The commands used to accomplish this
reformatting were as follows (with current working directory as the root of
the repository):
find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} +
find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ;
The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.
Secondly, “blame” style tools will generally point to this commit instead of
a meaningful prior commit. There are alternatives available that will attempt
to look through this change and find the appropriate prior commit. YMMV.

Summary:
- copies the new file in the cmake build
- adds an additional import statement
- marks the test as no-debug-info specific, as it seems to be testing a python feature

This class enables one to easily write a synthetic child provider by writing a class that returns pairs of names and primitive Python values - the base class then converts those into LLDB SBValues
Comes with a test case
llvm-svn: 280172
If a lldbinline test's source file changed language, then the Makefile wasn't
updated. This was a problem if the Makefile was checked into the repository.
Now lldbinline.py always regenerates the Makefile and asserts if the
newly-generated version is not the same as the one already there. This ensures
that the repository will never be out of date without a buildbot failing.

T x;
U y;
doing
x = *((T*)y)
is undefined behavior, even if sizeof(T) == sizeof(U), due to pointer aliasing rules
Fix up a couple of places in LLDB that were doing this, and transform them into a defined and safe memcpy() operation
Also, add a test case to ensure we didn't regress by doing this w.r.t. tagged pointer NSDate instances

The adding of <atomic> to test_common.h broke 12 tests on Darwin. We work around this by not including <atomic> when building on darwin for libstdc++ tests.

This option evaluates an expression and, if the result is of pointer type, treats it as if it was an array of that many elements and displays such elements
This has a couple subtle points but is mostly as straightforward as it sounds
Add a parray N <expr> alias for this new mode
Also, extend the --object-description mode to do the moral equivalent of the above but display each element in --object-description mode
Add a poarray N <expr> alias for this

A number of test cases were failing on big-endian systems simply due to
byte order assumptions in the tests themselves, and no underlying bug
in LLDB.
These two test cases:
tools/lldb-server/lldbgdbserverutils.py
python_api/process/TestProcessAPI.py
actually check for big-endian target byte order, but contain Python errors
in the corresponding code paths.
These test cases:
functionalities/data-formatter/data-formatter-python-synth/TestDataFormatterPythonSynth.py
functionalities/data-formatter/data-formatter-smart-array/TestDataFormatterSmartArray.py
functionalities/data-formatter/synthcapping/TestSyntheticCapping.py
lang/cpp/frame-var-anon-unions/TestFrameVariableAnonymousUnions.py
python_api/sbdata/TestSBData.py (first change)
could be fixed to check for big-endian target byte order and update the
expected result strings accordingly. For the two synthetic tests, I've
also updated the source to make sure the fake_a value is always nonzero
on both big- and little-endian platforms.
These test case:
python_api/sbdata/TestSBData.py (second change)
functionalities/memory/cache/TestMemoryCache.py
simply accessed memory with the wrong size, which wasn't noticed on LE
but fails on BE.

Enrico has a bug on him to make this work across older libcxx list
and newer libcxx list simultaneously. Needed in preparation of
getting the OS X public CI to run the TSAN tests.

We want to do a better job presenting errors that occur when evaluating
expressions. Key to this effort is getting away from a model where all
errors are spat out onto a stream where the client has to take or leave
all of them.
To this end, this patch adds a new class, DiagnosticManager, which
contains errors produced by the compiler or by LLDB as an expression
is created. The DiagnosticManager can dump itself to a log as well as
to a string. Clients will (in the future) be able to filter out the
errors they're interested in by ID or present subsets of these errors
to the user.
This patch is not intended to change the *users* of errors - only to
thread DiagnosticManagers to all the places where streams are used. I
also attempt to standardize our use of errors a bit, removing trailing
newlines and making clients omit 'error:', 'warning:' etc. and instead
pass the Severity flag.
The patch is testsuite-neutral, with modifications to one part of the
MI tests because it relied on "error: error:" being erroneously
printed. This patch fixes the MI variable handling and the testcase.

This can cause differences in which bit patterns end up meaning YES or NO. In general, however, 0 == NO and 1 == YES.
To keep it simple, LLDB will now show "YES" and "NO" only for 1 and 0 respectively, and format other values as the plain numeric value instead.

On libc++ std::atomic is a fairly simple data type (layout wise, at least), wrapping actual contents in a member variable named "__a_"
All the formatters are doing is "peel away" this intermediate layer and exposing user data as direct children or values of the std::atomic root variable
Fixes rdar://24329405

However, they also contain fallback logic that - in cases where LLDB can't recognize the specific subclass - actually does run code in order to inspect those objects.
The argument for this logic was that these data types are critical enough that the risk of getting it wrong is outweighed by the advantage of always providing accurate child information.
Practical experience however shows that "po" - a code running data-inspection command - is quite frequently used, and not considered burdensome by users.
As such, this makes the code-running fallback in the data formatters a risk that carries very little actual reward. Also, unlike the time this code was originally written, we now have accurate class information for Objective-C, and thus we are less likely to improperly identify classes.
This commit removes support for the code-running fallback, and aligns the data formatters for NSArray, NSDictionary and NSSet to the general no-code-running behavior of other data formatters.
While it is possible for us to add support for some subclasses that are now no longer covered by static inspection alone, this is beyond the scope of this commit.

expectedFailureWindows is equivalent to using the general
expectedFailureAll decorator with oslist="windows". Additionally,
by moving towards these common decorators we can solve the issue
of having to support decorators that can be called with or without
arguments. Once all decorators are always called with arguments,
and this is enforced by design (because you can't specify the condition
you're decorating for without passing an argument) the implementation
of the decorators can become much simpler
