The DWARFExpression is parsing the location lists in about five places.
Of those, only one actually had proper support for base address
selection entries.
Since r374600, llvm has started to produce location expressions with
base address selection entries more aggresively, which caused some tests
to fail.
This patch adds support for these entries to the places which had it
missing, fixing the failing tests. It also adds a targeted test for the
two of the three fixes, which should continue testing this functionality
even if the llvm output changes. I am not aware of a way to write a
targeted test for the third fix (DWARFExpression::Evaluate).

Before the reorganiziation, the API tests were inheriting the timeout
from the top-level lit file. Now that this is no longer the case, the
lldb-api test suite needs to set its own timeout.

Before the test reorganization, everything was part of a single test
suite with a single module cache. Now that things are properly separated
this is no longer the case. Only the shell tests inherited the logic to
properly configure and wipe the module caches. This patch adds that
logic back for the API tests. While doing so, I noticed that we were
configuring a Clang module cache in CMake, but weren't actually using it
from dotest.py. I included a fix for that in this patch as well.

LLDB has three major testing strategies: unit tests, tests that exercise
the SB API though dotest.py and what we currently call lit tests. The
later is rather confusing as we're now using lit as the driver for all
three types of tests. As most of this grew organically, the directory
structure in the LLDB repository doesn't really make this clear.
The 'lit' tests are part of the root and among these tests there's a
Unit and Suite folder for the unit and dotest-tests. This layout makes
it impossible to run just the lit tests.
This patch changes the directory layout to match the 3 testing
strategies, each with their own directory and their own configuration
file. This means there are now 3 directories under lit with 3
corresponding targets:
- API (check-lldb-api): Test exercising the SB API.
- Shell (check-lldb-shell): Test exercising command line utilities.
- Unit (check-lldb-unit): Unit tests.
Finally, there's still the `check-lldb` target that runs all three test
suites.
Finally, this also renames the lit folder to `test` to match the LLVM
repository layout.

The custom target for the system debugserver has no install target, so

llvm-svn: 372793
r366433 broke support for the system debugserver. Although the change
was well-intended, it (presumably) unintentionally removed the logic to
copy over the debugserver. As a result, even with
LLDB_USE_SYSTEM_DEBUGSERVER enabled, we ended up building, signing and
using the just-built debugserver.
This patch partially recovers the old behavior: when
LLDB_USE_SYSTEM_DEBUGSERVER is set we don't build debugserver and just
copy over the system one.

Currently, lit tests don't set neither the module cache for building
inferiors nor the module cache used by lldb when running tests.
Furthermore, we have several places where we rely on the path to the
module cache being always the same, rather than passing the correct
value around. This makes it hard to specify a different module cache
path when debugging a a test.
This patch reworks how we determine and pass around the module cache
paths and fixes the omission on the lit side. It also adds a sanity
check to the lit and dotest suites.

* `LLDB_FRAMEWORK_INSTALL_DIR` **only** determines target directory in install-tree
* `LLVM_EXTERNALIZE_DEBUGINFO` allows externalized debug info (dSYM on Darwin, emitted to `bin`)
* `LLDB_FRAMEWORK_TOOLS` determines which executables will be copied to the framework's Resources (dropped symlinking, removed INCLUDE_IN_SUITE, removed dummy targets)
Other changes:
* clean up `add_lldb_executable()`
* include `LLDBFramework.cmake` from `source/API/CMakeLists.txt`
* use `*.plist.in` files, which are typical for CMake and independent from Xcode
* add clang headers to the framework bundle

Recently I tried to port LLDB's lit configuration files over to use a
on the surface, but broke some cases that weren't broken before and also
exposed some additional problems with the old approach that we were just
getting lucky with.
When we set up a lit environment, the goal is to make it as hermetic as
possible. We should not be relying on PATH and enabling the use of
arbitrary shell commands. Instead, only whitelisted commands should be
allowed. These are, generally speaking, the lit builtins such as echo,
cd, etc, as well as anything for which substitutions have been
explicitly set up for. These substitutions should map to the build
output directory, but in some cases it's useful to be able to override
this (for example to point to an installed tools directory).
This is, of course, how it's supposed to work. What was actually
happening is that we were bringing in PATH and LD_LIBRARY_PATH and then
just running the given run line as a shell command. This led to problems
such as finding the wrong version of clang-cl on PATH since it wasn't
even a substitution, and flakiness / non-determinism since the
environment the tests were running in would change per-machine. On the
other hand, it also made other things possible. For example, we had some
tests that were explicitly running cl.exe and link.exe instead of
clang-cl and lld-link and the only reason it worked at all is because it
was finding them on PATH. Unfortunately we can't entirely get rid of
these tests, because they support a few things in debug info that
clang-cl and lld-link don't (notably, the LF_UDT_MOD_SRC_LINE record
which makes some of the tests fail.
The high level changes introduced in this patch are:
1. Removal of functionality - The lit test suite no longer respects
LLDB_TEST_C_COMPILER and LLDB_TEST_CXX_COMPILER. This means there is no
more support for gcc, but nobody was using this anyway (note: The
functionality is still there for the dotest suite, just not the lit test
suite). There is no longer a single substitution %cxx and %cc which maps
to <arbitrary-compiler>, you now explicitly specify the compiler with a
substitution like %clang or %clangxx or %clang_cl. We can revisit this
in the future when someone needs gcc.
2. Introduction of the LLDB_LIT_TOOLS_DIR directory. This does in spirit
what LLDB_TEST_C_COMPILER and LLDB_TEST_CXX_COMPILER used to do, but now
more friendly. If this is not specified, all tools are expected to be
the just-built tools. If it is specified, the tools which are not
themselves being tested but are being used to construct and run checks
(e.g. clang, FileCheck, llvm-mc, etc) will be searched for in this
directory first, then the build output directory.
3. Changes to core llvm lit files. The use_lld() and use_clang()
functions were introduced long ago in anticipation of using them in
lldb, but since they were never actually used anywhere but their
respective problems, there were some issues to be resolved regarding
generality and ability to use them outside their project.
4. Changes to .test files - These are all just replacing things like
clang-cl with %clang_cl and %cxx with %clangxx, etc.
5. Changes to lit.cfg.py - Previously we would load up some system
environment variables and then add some new things to them. Then do a
bunch of work building out our own substitutions. First, we delete the
system environment variable code, making the environment hermetic. Then,
we refactor the substitution logic into two separate helper functions,
one which sets up substitutions for the tools we want to test (which
must come from the build output directory), and another which sets up
substitutions for support tools (like compilers, etc).
6. New substitutions for MSVC -- Previously we relied on location of
MSVC by bringing in the entire parent's PATH and letting
subprocess.Popen just run the command line. Now we set up real
substitutions that should have the same effect. We use PATH to find
them, and then look for INCLUDE and LIB to construct a substitution
command line with appropriate /I and /LIBPATH: arguments. The nice thing
about this is that it opens the door to having separate %msvc-cl32 and
%msvc-cl64 substitutions, rather than only requiring the user to run
vcvars first. Because we can deduce the path to 32-bit libraries from
64-bit library directories, and vice versa. Without these substitutions
this would have been impossible.

This patch restructures part of LLDB's testing configuration:
1. I moved the test dependencies up the chain so every dotest dependency
becomes a lit dependency as well. It wouldn't make sense for dotest to
have other dependencies when it's being run by lit. Lit on the other
hand can still specify extra dependencies.
2. I replaced as much generator expressions with variables as possible.
This is consistent with the rest of LLVM and doesn't break generators
that support multiple targets (MSVC, Xcode). This wasn't a problem
before, but now we need to expand the dotest arguments in the lit
configuration and there's only one test suite even with multiple
targets.
3. I moved lldb-dotest into it's own directory under utils since there's
no need anymore for it to located under `test/`.

llvm-svn: 331277
The current way that the lit configuration is generated for the LLDB
tests that run using dotest causes cmake to fail when using a generator
which supports multiple configurations (such as Visual Studio). The
failure is because file GENERATE will create a file *per possible
configuration* resulting in the same lit configuration file being
overwritten multiple times.
To fix the issue, we need to create a single lit file that is agnostic
of the configurations and can be used for any configuration.

Obviously the goal is maintain full compatibility with the functionality

llvm-svn: 328020
Summary:
This patch implements a unified way of cleaning the build folder of each
test. This is done by completely removing the build folder before each
test, in the respective setUp() method. Previously, we were using a
combination of several methods, each with it's own drawbacks:
- nuking the entire build tree before running dotest: the issue here is
that this did not take place if you ran dotest manually
- running "make clean" before the main "make" target: this relied on the
clean command being correctly implemented. This was usually true, but
not always.
- for files which were not produced by make, each python file was
responsible for ensuring their deleting, using a variety of methods.
With this approach, the previous methods become redundant. I remove the
first two, since they are centralized. For the other various bits of
clean-up code in python files, I indend to delete it when I come
across it.

This adds a wrapper around dotest, similar to llvm-lit in llvm. The
wrapper is created in the binary directory, next to LLDB and allows you
to invoke dotest without having to pass any of the configuration
arguments yourself. I think this could also be useful for re-running a
particular test case when it fails, as an alternative to "Command
Invoked".
The motivation for this is that I'd like to replace the driver part of
dotest with lit. As a first step, I'd like to have lit invoke dotest,
which would just run the complete test suite, completely identical to
what the CMake target does today. Once this is in place, we can have lit
run dotest for the different test directories, and ultimately once per
python file. Along the way we can strip out driver functionality from
dotest where appropriate.

For each test (should be eventually: each test configuration) a
separate build directory is created and we execute
make VPATH=$srcdir/path/to/test -C $builddir/path/to/test -f $srcdir/path/to/test/Makefile -I $srcdir/path/to/test
In order to make this work all LLDB tests need to be updated to find
the executable in the test build directory, since CWD still points at
the test's source directory, which is a requirement for unittest2.
Although we have done extensive testing, I'm expecting that this first
attempt will break a few bots. Please DO NOT HESITATE TO REVERT this

Summary:
CMake has no builtin mechanism for cache invalidation. As a general convention you want to not expand user-specified variables in other cached variables because they will not get updated when the user changes their specified value.
This patch moves the "-C" option for dotest.py into the LLDB_TEST_COMMON_ARGS and out of the CMake cache. In order to prevent issues with out-of-date cache files on builders I've added code to scrub "-C ${LLDB_TEST_COMPILER}" out of the CMake caches, by Force writing the variable. This code can be removed in a few days once the change has trickled through CI systems.

This patch adds the following fixes to the check-lldb targets:
* Adds missing dependencies on lldb tools so they get built before tests execute
* Adds Ninja USES_TERMINAL to the target so that the output streams to stdout as it executes
* Uses a generator expression to find the lldb executable, this is more robust than constructing the path manually

*** 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.

This change deprecates -m/+m dotest options (the options are still recognized but they print an

run lldb-mi tests, use '-G lldb-mi'. To skip lldb-mi tests, use '--skip-category lldb-mi'. All
lldb-mi tests are marked as such using the getCategories method on the base MiTestCaseBase class
and the @lldbmi_test decorator is not needed. In case one still needs to annotate a specific test
function as an lldb-mi test, one can use the @add_test_categories(['lldb-mi']) decorator to
achieve that.

This is necessary in order to allow third party modules to be

Since we're already touching every test file anyway, we also
go ahead and delete the unittest2 import and main block wherever
possible. The ability to run a test as a standalone file has
already been broken for some time, and if we decide we want this

Summary:
Along with this, support for an optional argument to the "num_children"
method of a Python synthetic child provider has also been added. These have
been added with the following use case in mind:
Synthetic child providers currently have a method "has_children" and
"num_children". While the former is good enough to know if there are
children, it does not give any insight into how many children there are.
Though the latter serves this purpose, calculating the number for children
of a data structure could be an O(N) operation if the data structure has N
children. The new method added in this change provide a middle ground.
One can call GetNumChildren(K) to know if a child exists at an index K
which can be as large as the callers tolerance can be. If the caller wants
to know about children beyond K, it can make an other call with 2K. If the
synthetic child provider maintains state about it counting till K
previosly, then the next call is only an O(K) operation. Infact, all
calls made progressively with steps of K will be O(K) operations.

Summary:
Loop detection code is being called before every element access. Although it tries to cache some
of the data by remembering the loop-free initial segment, every time it needs to increase this
segment, it will start from scratch. For the typical usage pattern, where one accesses the
elements in order, the loop detection will need to be run after every access, resulting in
quadratic behavior. This behavior is noticable even for the default 255 element limit.
In this commit, I rewrite the algorithm to be truly incremental -- it maintains the state of its
loop-detection runners between calls, and reuses them when it needs to check another segment.
This way, each part of the list is scanned only once, resulting in linear behavior.
Also note that I have changed the operator== of ListEntry to do the comparison based on the
value() function (instead of relying on ValueObjectSP equality). In my experiments, I kept
getting different ValueObjectSPs when going through the same element twice.

Right now our Python code does not all share a common root. Tests and
scripts both contain python code that cannot take advantage of reusability
since they are unrelated siblings of each other.
In particular, this presents a problem for wanting to use third party
packages from both sides, since it does not make sense to copy the module
into both places.
This patch solves this by introducing a script lldb_shared.py which is a
very lightweight script that just searches up the tree until it finds a
root, and then imports a module from there. That module knows how to
find all of the shared code that LLDB uses, and adjusts sys.path
accordingly to make them all visible.

Currently most of the test files have a separate dwarf and a separate
dsym test with almost identical content (only the build step is
different). With adding dwo symbol file handling to the test suit it
would increase this to a 3-way duplication. The purpose of this change
is to eliminate this redundancy with generating 2 test case (one dwarf
and one dsym) for each test function specified (dwo handling will be
added at a later commit).
Main design goals:
* There should be no boilerplate code in each test file to support the
multiple debug info in most of the tests (custom scenarios are
acceptable in special cases) so adding a new test case is easier and
we can't miss one of the debug info type.
* In case of a test failure, the debug symbols used during the test run
have to be cleanly visible from the output of dotest.py to make
debugging easier both from build bot logs and from local test runs
* Each test case should have a unique, fully qualified name so we can
run exactly 1 test with "-f <test-case>.<test-function>" syntax
* Test output should be grouped based on test files the same way as it
happens now (displaying dwarf/dsym results separately isn't
preferable)
Proposed solution (main logic in lldbtest.py, rest of them are test
cases fixed up for the new style):
* Have only 1 test fuction in the test files what will run for all
debug info separately and this test function should call just
"self.build(...)" to build an inferior with the right debug info
* When a class is created by python (the class object, not the class
instance), we will generate a new test method for each debug info
format in the test class with the name "<test-function>_<debug-info>"
and remove the original test method. This way unittest2 see multiple
test methods (1 for each debug info, pretty much as of now) and will
handle the test selection and the failure reporting correctly (the
debug info will be visible from the end of the test name)
* Add new annotation @no_debug_info_test to disable the generation of
multiple tests for each debug info format when the test don't have an
inferior

Summary:
With this change DWARFASTParserClang::CompleteTypeFromDWARF returns false if
DWARFASTParserClang::ParseChildMembers returns false. Similarly, it returns
false if any base class is of an incomplete type. This helps in cases like
these:
class Foo
{
public:
std::string str;
};
...
Foo f;
If a file with the above code is compiled with a modern clang but without
the -fno-limit-debug-info (or similar) option, then the DWARF has only
a forward declration for std::string. In which case, the type for
"class Foo" cannot be completed. If LLDB does not detect that a child
member has incomplete type, then it wrongly conveys to clang (the LLDB
compiler) that "class Foo" is complete, and consequently crashes due to
an assertion failure in clang when running commands like "p f" or
"frame var f".

* --results-formatter-options renamed to --results-formatter-option,
with short version of -O
* Multiple --results-formatter-option=OPTION can be specified. The
comma-separating mechanism has been removed.
* XunitFormatter options modified: -n and -r are now short forms of
--ignore-skip-name and --ignore-skip-reason. Those long option
names were tweaked lightly. They also can be specified multiple
times on the command line. The comma-separating, multiple-pattern-
per-option mechanism has been removed.
One can now specify:
dotest.py --results-file stdout -O-ndsym -O-nlldb-mi
for example, to ignore reporting skips for dsym-related or lldb-mi-related
tests in the xUnit report.

Summary:
The following situation occured in TestAttachResume:
The inferior was stoped at a breakpoint and we did a continue, immediately followed by a detach.
Since there was a trap instruction under the IP, the continue did a step-over-breakpoint before
resuming the inferior for real. In some cases, the detach command was executed between these two
events (after the step-over stop, but before continue). Here, public state was running, but
private state was stopped. This caused a problem because HaltForDestroyOrDetach was checking the
public state to see whether it needs to stop the process (call Halt()), but Halt() was checking
the private state and concluded that there is nothing for it to do.
Solution: Instead of Halt() call SendAsyncInterrupt(), which will then cause Halt() to be
executed in the context of the private state thread. I also rename HaltForDestroyOrDetach to
reflect it does not call halt directly.

When doing test event collation from dotest inferiors to the parallel test
runner, I had a hard-coded small value for the socket backlog. Fix it to
be 2*num workers so we don't fail socket connections from inferiors.

I'm seeing timed out tests not properly timing out on the Linux
build bot after this change. Not sure if it is related but
seems suspect.

These two tests are skipped on Linux with a comment that the behaviour
is as expected, but they are consistently passing on FreeBSD now.

llvm-svn: 248271
Skipped tests can be dropped from xUnit reports if either
the name or the skip reason matches one of a given set of
regular expression patterns (via re.search(), not re.match()).
New formatter option for the xunit formatter:
--ignore-skip-matching-reason and
--ignore-skip-matching-name
Both are results-formatter options.

Added key press handling and a first responder system and the ability for windows that can be first responders to be selected and have key presses routed to the first resonder, delegates and also travel up the parent chain.
Remove the temp file that was being created.

The parallel test runner now sends the terminate event to the formatter
(if there is one) after the parallel test runs but before dumping anything
to stdout/stderr at the end of the run. This allows the existing
stdout/stderr summary reporting to co-exist nicely with a formatter like
the test_results.Curses that otherwise clobbers the screen.

- rename "Failures" window to "Completed Tests"
- Remove the extra lock that I incorrectly added to the ResultsFormatter as it already had one
- Init the curses GUI with the right number of jobs when handling the "intialize" event
- tear down the curses GUI when tests complete

On OS X, we're occasionally seeing sighups come in to what
looks like the whole test runner process group (all the
multiprocessing workers and the main process). It's not due
to a lost console. This change has the main parallel test runner
process and the child worker processes ignore sighup.

The test events had worker indexes coming across as strings. I
want them to be ints. worker_index now comes across as an int in
the dicationary.
The optional type can be specified with:
--event-add-entries key=val[:type][,key2=val2[:type2]...]
The type piece may be 'int' at this time. That is all. Otherwise
it will be a string.

The failure mode when one gets this wrong is quite gnarly to then walk oneself out of, and if you can't actually find the library, trying to build against it is fairly pointless anyway
This + my previous skip_if_library_missing change should make running the libc++ tests on a Linux machine without it much more seamless

Now does proper Unicode code region scanning for invalid XML
characters. Strips out XML-invalid characters.
Does this for:
failure result: message, backtrace
error result: message, backtrace
skipped test: skip reason
pexpect timeouts were still generating characters that would break
XML readers (correctly so).
llvm-svn: 247998
When pexpect errors occurred, the <error>/<failure> element's
message attribute could get too long and contain
invalid characters for xml attributes, even when quoted.
Particularly for pexpect failures.
Now <error> and <failure> entries truncate the message
attribute to contain the first line of the message.
<error> and <failure> blocks now contain both the
complete message and the backtrace (finally!) in the
text body of the error/failure element.
llvm-svn: 247973
The Jenkins JUnit publisher handled our output, but
the Jenkins xUnit plugin's JUnit support did not like
that we didn't have a <testsuites> element wrapping
everything. They both work with this fix.

This fixes -data-info-line and -symbol-list-lines to parse the filename
and line correctly when line entries don't have the optional column
number and the filename contains a Windows drive letter. It also fixes
-symbol-list-lines when code from header files is generated.

Summary: Supports the parsing of the "using namespace XXX" and "using XXX::XXX" directives. Added ambiguity errors when it two decls with the same name are encountered (see comments in TestCppNsImport). Fixes using directives being duplicated for anonymous namespaces. Fixes GetDeclForUID for specification DIEs.

ExprCommandWithTimeoutsTestCase::expectedFailureFreeBSD had an
expectedFailureFreeBSD decorator, removed in r247799. It had been flakey
on the FreeBSD buildbot but passed locally. John Wolfe has since
observed a local failure, so add expectedFlakeyFreeBSD until we can
investigate and likely increase the timeout in the test.

"gcc" register numbers are now correctly referred to as "ehframe"
register numbers. In almost all cases, ehframe and dwarf register
numbers are identical (the one exception is i386 darwin where ehframe
regnums were incorrect).
The old "gdb" register numbers, which I incorrectly thought were
stabs register numbers, are now referred to as "Process Plugin"
register numbers. This is the register numbering scheme that the
remote process controller stub (lldb-server, gdbserver, core file
support, kdp server, remote jtag devices, etc) uses to refer to the
registers. The process plugin register numbers may not be contiguous
- there are remote jtag devices that have gaps in their register
numbering schemes.
I removed all of the enums for "gdb" register numbers that we had
in lldb - these were meaningless - and I put LLDB_INVALID_REGNUM
in all of the register tables for the Process Plugin regnum slot.
This change is almost entirely mechnical; the one actual change in
here is to ProcessGDBRemote.cpp's ParseRegisters() which parses the
qXfer:features:read:target.xml response. As it parses register
definitions from the xml, it will assign sequential numbers as the
eRegisterKindLLDB numbers (the lldb register numberings must be
sequential, without any gaps) and if the xml file specifies register
numbers, those will be used as the eRegisterKindProcessPlugin
register numbers (and those may have gaps). A J-Link jtag device's
target.xml does contain a gap in register numbers, and it only
specifies the register numbers for the registers after that gap.
The device supports many different ARM boards and probably selects
different part of its register file as appropriate.

Linux/clang on clang 3.6+ is passing this test. As OS X was
in a similar position, I'm guessing this was fixed by a recent
compiler. Might work on 3.5/3.4, but it is definitely working
on clang 3.6. I didn't break out FreeBSD since this appears to
be related to a compiler fix.
