Summary:
r327219 adds wrappers to sort which shuffle the container before sorting.
This causes lldb bots to break as the call to sort is now ambiguous:
http://lab.llvm.org:8011/builders/lldb-x86_64-ubuntu-14.04-buildserver/builds/20725/steps/ninja%20build%20local/logs/stdio
So we need use llvm::sort instead of sort to avoid ambiguity with std::sort.
Note: This patch is just to unbreak the bots. I plan to have subsequent patches which will convert all
calls to std::sort to llvm::sort.

Besides being superfluous, this double merging was actually wrong and

Summary:
The args class is used in plenty of places (a lot of them in the lower lldb
layers) for representing a list of arguments, and most of these places don't
care about option parsing. Moving the option parsing out of the class removes
the largest external dependency (there are a couple more, but these are in
static functions), and brings us closer to being able to move it to the
Utility module).
The new home for these functions is the Options class, which was already used
as an argument to the parse calls, so this just inverts the dependency between
the two.
The functions are themselves are mainly just copied -- the biggest functional
change I've made to them is to avoid modifying the input Args argument (getopt
likes to permute the argument vector), as it was weird to have another class
reorder the entries in Args class. So now the functions don't modify the input
arguments, and (for those where it makes sense) return a new Args vector
instead. I've also made the addition of a "fake arg0" (required for getopt
compatibility) an implementation detail rather than a part of interface.
While doing that I noticed that ParseForCompletion function was recording the
option indexes in the shuffled vector, but then the consumer was looking up the
entries in the unshuffled one. This manifested itself as us not being able to
complete "watchpoint set variable foo --" (because getopt would move "foo" to
the end). Surprisingly all other completions (e.g. "watchpoint set variable foo
--w") were not affected by this. However, I couldn't find a comprehensive test
for command argument completion, so I consolidated the existing tests and added
a bunch of new ones.

The test was failing in remote debugging scenario with windows as a host
as cmd.exe is not able to parse the complicated shell commands in the

The test seemed like a perfect candidate for a more focused testing
approach, so I have rewritten in on top of lldb-test's module-sections
functionality. The slight gotcha there was that the
Module::GetSectionList does not include the sections from the symbol
file until someone manually calls Module::GetSymbolVendor. Normally,
this is not an issue, because someone will have initialized the symbol
vendor by the time anyone starts looking at the sections. However, when
all one this is dump the section list, we run into this problem.
I've tried making this behavior more automatic, but it turns out it's
not that easy, so for now, I just manually initialize the Symbol Vendor
before dumping out the sections in lldb-test.

This adds a wrapper around dotest, similar to llvm-lit in llvm. The

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.

to different tests.
With the workaround in place, assigning a category to one test resulted

diverged from the original intention and now it creates the threads *after* the
watchpoint is set (this probably happened during the std::thread refactor).
After some discussion, we decided both scenarios make sense, so I modify the
test to test both.
The watchpoint propagation functionality is not really debug info depenent, so
I also stop replication of this test. This brings the test's time from ~108s

- Add support for querying the target's qXfer:memory-map, which contains information about flash memory regions, leveraging MemoryRegionInfo data structures with minor modifications
- Update ProcessGDBRemote to use vFlash commands in DoWriteMemory when the target address is in a flash region

Without this fix, the test ERRORs because the link of the inferior fails. This

With this fix, the test itself still fails: conflicting_symbol isn't in the

of the ELF .symtab. We need to understand why the test works to keep the

Summary:
The command takes two input arguments: a module to use as a debug target
and a file containing a list of commands. The command will execute each
of the breakpoint commands in the file and dump the breakpoint state
after each one.
The commands are expected to be breakpoint set/remove/etc. commands, but
I explicitly allow any lldb command here, so you can do things like
change setting which impact breakpoint resolution, etc. There is also a
"-persistent" flag, which causes lldb-test to *not* automatically clear
the breakpoint list after each command. Right now I don't use it, but
the idea behind it was that it could be used to test more complex
combinations of breakpoint commands (set+modify, set+disable, etc.).
Right now the command prints out only the basic breakpoint state, but
more information can be easily added there. To enable easy matching of
the "at least one breakpoint location found" state, the command
explicitly prints out the string "At least one breakpoint location.".
To enable testing of breakpoints set with an absolute paths, I add the
ability to perform rudimentary substitutions on the commands: right now
the string %p is replaced by the directory which contains the command
file (so, under normal circumstances, this will perform the same
substitution as lit would do for %p).
I use this command to rewrite the TestBreakpointCaseSensitivity test --
the test was checking about a dozen breakpoint commands, but it was
launching a new process for each one, so it took about 90 seconds to
run. The new test takes about 0.3 seconds for me, which is approximately
a 300x speedup.

this for the handful of inferiors that actually care about their PWD,

The paralelization patch exposed a bunch of cases where we were still

This patch removes such issues from breakpoint command tests. Since the
only reason they were creating files was to indirectly test whether the
breakpoint commands got executed (and plumbing the full build tree path
to all places that needed it would be messy) I decided to modify the
tests to check for a different side effect instead: modification of a
global variable. This also makes the code simpler as checking the value
of the global variable is easier, and there is nothing to clean up.
As the tests aren't really doing anything debug-info related, I took the

Before this patch, LLDB was not able to evaluate expressions that
resulted in a value with a typeof- or decltype-type. This patch fixes
that.
Before:
(lldb) p int i; __typeof__(i) j = 1; j
(typeof (i)) $0 =
After:
(lldb) p int i; __typeof__(i) j = 1; j
(typeof (i)) $0 = 1

The first issue is about the flaky test rerun logic. This was grouping
tests by subdir and passing them into walk_and_invoke in the incorrect
form. This part can be just deleted as its not needed anymore.
The second problem (which I noticed while investigating the first one)
was that the "-p" switch was not working in multiprocessing mode. This
happened because we were returning None from process_file instead of a
tuple full of empty values for tests that did not match the -p regex.
Both of these would be caught earlier if python was a more strongly
typed language. :/

Summary:
The issue was that we were parsing the registers into 64-bit integers
and the calling swapByteOrder without regard for the actual size of the
register. This switches the test to use the RegisterValue class which
tracks the register size, and knows how to initialize itself from a
piece of memory (so we don't need to swap byte order ourselves).

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).

These were missed in the great refactor because they were added
concurrently with it. Since we started running tests in a more parallel
fashion they started to be flaky. This should fix it.
Now that we are no longer polluting the source tree, I also delete the
bit of custom cleanup code specific to these tests.

Summary:
Consolidate LLDB_CODESIGN_IDENTITY logic in one place and use
SKIP_DEBUGSERVER, which can be set independently, to control
codesigning targets.
Currently, running cmake the first time in a clean directory, without
passing -DLLDB_CODESIGN_IDENTITY='', fails. However, subsequent runs
succeed. That's because LLDB_CODESIGN_IDENTITY gets added to the
CACHE after the initial test. To fix that, the default value must be
set before it's tested.
Here's the error produced on the first run:
CMake Error at tools/lldb/tools/debugserver/source/CMakeLists.txt:215 (add_custom_command):
No TARGET 'debugserver' has been created in this directory.

The test was generating long unix socket names, and the addition of a
new folder in the previous patch pushed it over the limit (although
linux has a fairly generous limit for path names, this does not apply to
unix sockets).
Modify the test to use a shorter name instead.

The reason this test was disabled is no longer relevant. However, it
didn't turn into an unexpected success because of a syntax error in the
test itself. This commit fixes that and re-enables the test.

Since we now can run multiple tests from the same directory at once, we
need to include the test name in the remote test directory instead.
I'm not sure if the test_number in the remote path is necessary anymore
(or even if it was ever necessary), but I choose to leave it in for now.

Summary:
The PowerPC64 ABI plugin was modified to:
- properly handle vector type return values
- implement support for struct/class return values
A refactoring in the code that handles return values was also performed, to make it possible to handle structs without repeating (when possible) code that handles its fields.
There was also an issue with CreateInstance(), that only created an instance in the first time it was called and then cached it in a static var. When restarting a process under LLDB's control, the ABI's process weak pointer would become null, and using it would result in a segmentation fault. This issue became more evident after the latest changes to PPC64 plugin, that now uses the process pointer to get the target byte order, making LLDB to seg fault when restarting a program. This was fixed by making CreateInstance() to always create a new ABI instance.
All of LLDB's ReturnValue tests are passing for PPC64le now. It should work for PPC64be too, although this was not tested.

Patch by Leandro Lupori <leandro.lupori@gmail.com>.
llvm-svn: 325324
Summary:
Due to in-tree builds, we were parallelizing the tests at the directory
level. Now that the tests are built out-of-tree, we can remove this
limitation and paralelize at file level instead.
This decreases test suite time by about 10% for me, which is not
world-shattering, but it makes the code slightly simpler and will also
allow us to merge tests which were artificially spread over multiple
folders (TestConcurrentEvents...) to work-around this limitation.
To make this work, I've also needed to include the test file name in the
build directory name, as just the test method name is not unique enough
(plenty of tests have a test method called "test" or similar).
While doing this, I've found a couple of tests that are taking waaay longer then
they ought to (TestBreakpointCaseSensitivity -- 90 seconds), which I plan to
look into in the future.

This test uses XML packets, but libxml is an optional dependency of
lldb, and this test fails if it is not present.
I'm leaving this enabled on mac, as thats the only platform that's
likely to have libxml always available, but ideally we should have a way
to skip this based on build configuration. I'll see if I can whip
something like that up soon, but for the time being, this unblocks the
buildbots.

This only worked on MacOS, which now ships a newer version of
python without this bug. As such, we don't leak the fd, and

Summary:
Right now the test client is not parsing register values correctly,
which is manifesting itself in one test failing on 32-bit architectures
(pr36013). This parses the information from the qRegisterInfo packets
and stores it in the client, which will enable fixing the parsing in a
follow up commit.
I am also adding a new templated SendMessage overload, which enables one
to send a message get a parsed response in a single call.

- Implement SymbolFilePDB::FindFunctions methods. On lldb console, searching function symbol by name and by regular expression are both available.
- Create lldb type for PDBSymbolFunc.
- Add tests to check whether functions with the same name but from different sources can be resolved correctly.

Summary:
The test was trying to reproduce a bug in handling of two concurrent
events, which was impossible to do reliably in a black-box style test.
In practice, this meant the test was only ever failing on remote
targets, as these were slow enough to trigger this.
Fortunately, we now have the ability to mock the server side of the
connection, which means we can simulate the failure deterministically,
so I rewrite the test to use the new gdb-client framework.
I've needed to add a couple of new packets to the mock server to be able
to do this. Instead of trying to guess how a "typical" gdb-client test
will want to handle this, I throw an exception in the implementation to
force the user to override them (the packets are only sent if the test
explicitly performs some action which will trigger them, so a basic test
which e.g. does not need the "continue" functionality will not need to
implement them).

This is a small change towards running the LLDB unit tests on Windows (still WIP).
Builds that use make do not point to specific configurations. However, builds with multiple configurations such as Visual Studio on Windows need the configuration (release/debug/etc) as part of the path so the binaries produced by clang are placed in the correct directory for the configuration.

Davide pointed out this would be useful if the file ever needs to be

ObjectFileELF::GetModuleSpecifications contained a lot of tip-toing code
which was trying to avoid loading the full object file into memory. It
did this by trying to load data only up to the offset if was accessing.
However, in practice this was useless, as 99% of object files we
encounter have section headers at the end, so we would load the whole
file as soon as we start parsing the section headers.
In fact, this would break as soon as we encounter a file which does
*not* have section headers at the end (yaml2obj produces these), as the
access to .strtab (which we need to get the section names) was not
guarded by this offset check.
As this strategy was completely ineffective anyway, I do not attempt to
proliferate it further by guarding the .strtab accesses. Instead I just
lead the full file as soon as we are reasonably sure that we are indeed
processing an elf file.
If we really care about the load size here, we would need to reimplement
this to just load the bits of the object file we need, instead of
loading everything from the start of the object file to the given
offset. However, given that the OS will do this for us for free when
using mmap, I think think this is really necessary.
For testing this I check a (tiny) SO file instead of yaml2obj-ing it
because the fact that they come out first is an implementation detail of
yaml2obj that can change in the future.
