The android dirty stderr problem has uncovered an issue where lldbutil.expect_state_changes was
reading events other than state change events, which resulted in general confusion. Make it more

On some android targets, a binary can produce additional garbage (e.g. warning messages from the

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)

This fixes several test case failure on s390x caused by the fact that
on this platform, the default "char" type is unsigned.
- In ClangASTContext::GetBuiltinTypeForEncodingAndBitSize we should return
an explicit *signed* char type for encoding eEncodingSint and bit size 8,
instead of the default platform char type (which may be unsigned).
This fix matches existing code in ClangASTContext::GetIntTypeFromBitSize,
and fixes the TestClangASTContext.TestBuiltinTypeForEncodingAndBitSize
unit test case.
- The test/expression_command/char/TestExprsChar.py test case is known to
fail on platforms defaulting to unsigned char (pr23069), and just needs
to be xfailed on s390x like on arm.
- The test/functionalities/watchpoint/watchpoint_on_vectors/main.c test
case defines a vector of "char" and implicitly assumes to be signed.
Use an explicit "signed char" instead.

This patch adds support for Linux on SystemZ:
- A new ArchSpec value of eCore_s390x_generic
- A new directory Plugins/ABI/SysV-s390x providing an ABI implementation
- Register context support
- Native Linux support including watchpoint support
- ELF core file support
- Misc. support throughout the code base (e.g. breakpoint opcodes)
- Test case updates to support the platform
This should provide complete support for debugging the SystemZ platform.
Not yet supported are optional features like transaction support (zEC12)
or SIMD vector support (z13).
There is no instruction emulation, since our ABI requires that all code
provide correct DWARF CFI at all PC locations in .eh_frame to support
unwinding (i.e. -fasynchronous-unwind-tables is on by default).
The implementation follows existing platforms in a mostly straightforward
manner. A couple of things that are different:
- We do not use PTRACE_PEEKUSER / PTRACE_POKEUSER to access single registers,
since some registers (access register) reside at offsets in the user area
that are multiples of 4, but the PTRACE_PEEKUSER interface only allows
accessing aligned 8-byte blocks in the user area. Instead, we use a s390
specific ptrace interface PTRACE_PEEKUSR_AREA / PTRACE_POKEUSR_AREA that
allows accessing a whole block of the user area in one go, so in effect
allowing to treat parts of the user area as register sets.
- SystemZ hardware does not provide any means to implement read watchpoints,
only write watchpoints. In fact, we can only support a *single* write
watchpoint (but this can span a range of arbitrary size). In LLDB this
means we support only a single watchpoint. I've set all test cases that
require read watchpoints (or multiple watchpoints) to expected failure
on the platform. [ Note that there were two test cases that install
a read/write watchpoint even though they nowhere rely on the "read"
property. I've changed those to simply use plain write watchpoints. ]

result_formatter used inspect.getfile() to get the python file name, which returned "*.pyc" if
the bytecode file was present. This resulted in files being displayed with the wrong extension,
and more critically, would confuse the rerun logic because it would try to rerun the pyc file
(which resulted in an empty rerun list as unittest refused to run those).
Fix: use inspect.getsourcefile() instead.
I am not sure why does was not an issue before. I can only assume that some system update

The result variables aren't useful, and if you have a breakpoint on a
common function you can generate a lot of these. So I changed the
code that checks the condition to set ResultVariableIsInternal in the
EvaluateExpressionOptions that we pass to the execution.
Unfortunately, the check for this variable was done in the wrong place
(the static UserExpression::Evaluate) which is not how breakpoint
conditions execute expressions (UserExpression::Execute). So I moved
the check to UserExpression::Execute (which Evaluate also calls) and made the
overridden method DoExecute.

This test sets the compiler optimization level to -O1 and
makes some assumptions about how local frame vars will be
stored (i.e. in registers). These assumptions are not always
true.
I did a first-pass set of improvements that:
(1) no longer assumes that every one of the target locations has
every variable in a register. Sometimes the compiler
is even smarter and skips the register entirely.
(2) simply expects one of the 5 or so variables it checks
to be in a register.
This test probably passes on a whole lot more systems than it
used to now. This is certainly true on OS X.

Teach LLDB that different shells have different characters they are sensitive to, and use that knowledge to do shell-aware escaping
This helps solve a class of problems on OS X where LLDB would try to launch via sh, and run into problems if the command line being passed to the inferior contained such special markers (hint: the shell would error out and we'd fail to launch)
This makes those launch scenarios work transparently via shell expansion
Slightly improve the error message when this kind of failure occurs to at least suggest that the user try going through 'process launch' directly

Summary:
the inferior in the test deliberately does not lock a mutex when accessing the watched variable.
The reason for that is unclear as, based on the logs, the original intention of the test was to
check whether watchpoints get propagated to newly created threads, which should work fine even
with a mutex. Furthermore, in the unlikely event (which I have still observed happening from time
to time) that two threads do manage the execute the "critical section" simultaneously, the test
will fail, as it is expecting the watchpoint "hit count" to be 1, but in this case it will be 2.
Given this, I have simply chose to lock the mutex always, so that we have more predictible
behavior. Watchpoints being hit simultaneously is still (and correctly!) tested by
TestConcurrentEvents.

1 - If you plan on looking for the "(lldb) " prompt as a regular expression, look for "\(lldb\) " so you don't just find "lldb".
2 - Make sure to not use colors (specify --no-use-colors as an option to lldb when launching it) as our editline will print:
"(lldb) <color junk>(lldb) "
where "<color junk>" is a work around that is used to allow us to colorize our prompts. The bad thing is this will make pexepct code like this not execute as you would expect:
prompt = "\(lldb\) "
self.child.sendline("breakpoint set ...", prompt)
self.child.sendline("breakpoint clear ...", prompt)
The problem is the first "sendline" will create two lldb prompts and will match both the first and second prompts and you output will get off. So be sure to disable colors if you need to.

Top-level Clang expressions are expressions that act as new translation units,
and define their own symbols. They do not have function wrappers like regular
expressions do, and declarations are persistent regardless of use of the dollar
sign in identifiers. Names defined by these are given priority over all other
symbol lookups.
This patch adds a new expression option, '-p' or '--top-level,' which controls
whether the expression is treated this way. It also adds a flag controlling
this to SBExpressionOptions so that this API is usable externally. It also adds
a test that validates that this works. (The test requires a fix to the Clang
AST importer which I will be committing shortly.)

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.

Summary:
Some tests (Hc_then_Csignal_signals_correct_thread, at least) were sending a "continue" packet in
one expect_gdbremote_sequence invocation, and "expecting" the stop-reply in another call. This
posed a problem, because the were packets were not persisted between the two invocations, and if
the stub was exceptionally fast to respond, the packet would be received in the first invocation
(where it would be ignored) and then the second invocation would fail because it could not find
the packet.
Since doing matching in two invocations seems like a reasonable use of the packet pump, instead
of fixing the test, I make sure the packet_pump supports this usage by making the list of
captured packets persistent.

The System-V x86_64 ABI requires floating point values to be passed
in 128-but SSE vector registers (xmm0, ...). When printing such a

This patch makes LLDB's DWARF expression evaluator accept 128-bit
registers as scalars. It also relaxes the check that the size of the
result of the DWARF expression be equal to the size of the variable to a
greater-than. DWARF defers to the ABI how smaller values are being placed
in a larger register.
Implementation note: I found the code in Value::SetContext() that changes
the m_value_type after the fact to be questionable. I added a sanity check
that the Value's memory buffer has indeed been written to (this is
necessary, because we may have a scalar value in a vector register), but
really I feel like this is the wrong place to be setting it.

The inlining semantics for C and C++ are different, which affects the test's expectation of the number of times the function should appear in the binary. In the case of this test, C semantics means there should be three instances of inner_inline, while C++ semantics means there should be only two.
On Windows, clang uses C++ inline semantics even for C code, and there doesn't seem to be a combination of compiler flags to avoid this.
So, for consistency, I've recast the test to use C++ everywhere. Since the test resided under lang/c, it seemed appropriate to move it to lang/cpp.

32-bit processes on 64-bit Windows run in a layer called WoW64 (Windows-on-Windows64). If you capture a mini dump of such a process from a 32-bit debugger, you end up with a register context for the 64-bit WoW64 process rather than the 32-bit one you probably care about.
This detects WoW64 by looking to see if there's a module named wow64.dll loaded. For such processes, it then looks in the 64-bit Thread Environment Block (TEB) to locate a copy of the 32-bit CONTEXT record that the plugin needs for the register context.

which would work, regardless of what the file was actually called.

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

Summary:
This does not yet give us a clean testsuite run but it does help with:
1. Actually building on linux
2. Run the testsuite with over 70% tests passing on linux.

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.

clearing the map ended up calling back into the TypeSystemMap to do lookups.
Not a good idea, and in this case it would cause a deadlock.
You would only see this when replacing the target contents after an exec, and only if you
had stopped before the exec, evaluated an expression, then continued
on to the point where you did the exec.
Fixed this by making sure the TypeSystemMap::Clear tears down the TypeSystems in the map before clearing the map.
I also add an expression before exec to the TestExec.py so that we'll catch this
issue if it crops up again in the future.

The explicit APIs on SBValue obviously remain if one wants to be explicit in intent, or override this guess, but since __int__() has to pick one, an educated guess is definitely better than than always going to signed regardless

CFLAGS is now being set correctly to pass -flimit-debug-info or
-fno-limit-debug-info on FreeBSD. I'm not sure which change is
responsible for the fix, though.

This removes the following decorators:
* skipIfI386
* expectedFailureI386
* expectedFailurex86_64
* skipIfArch
* skipUnlessArch
* skipUnlessI386
And other related decorators. All code using those decorators
is updated to use expectedFailureAll and skipIf

* Change the `not_in` function to be called `no_match`. This makes
it clear that keyword arguments can be more than just lists.
* Change the name of `_check_list_or_lambda` to
`_match_decorator_property`. Again clarifying that decorator params
are not always lists.
* Always use a regex match when matching strings. This allows automatic
support for regex matching on all decorator properties. Also support
compiled regex values.
* Fix a bug in the compiler check used by _decorateTest. The two
arguments were reversed, the condition was always wrong.
* Change one test that uses skipUnlessArch to use skipIf, to
demonstrate that skipIf can now handle more scenarios.

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
