Zachary Turner 7e3050ca1a [analyze-project-deps.py] Add the ability to list all cycles.
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.

Zachary Turner 82a0c97b32 Add a function to MD5 a file's contents.
In doing so, clean up the MD5 interface a little.  Most
existing users only care about the lower 8 bytes of an MD5,
but for some users that care about the upper and lower,
there wasn't a good interface.  Furthermore, consumers
of the MD5 checksum were required to handle endianness
details on their own, so it seems reasonable to abstract
this into a nicer interface that just gives you the right
value.

Pavel Labath 6b42b3b7a3 Fix remote test suite directory creation
r298203 make SBPlatform::MakeDirectory less recursive, which breaks the
test suite creation of test directory hierarchy creation on the remote
target. Since the function was never fully recursive, and the name does
not imply recursiveness, I fix the problem by modifying the test runner
to do the recursion manually.

I also make the runner complain more loudly when it fails to create the
directory -- previously it just printed the error to stdout and caused
most of the tests to hang, which is not very helpful in diagnosing the
problem.

Pavel Labath b7f0f45ffe Move GetAuxvData from Host to relevant process plugins
Summary:
GetAuxvData was causing dependencies from host to target and linux
process modules. It also does not fit netbsd use case, as there we can
only read the auxiliary vector with ptrace, which is better done in the
process plugin, with the other ptrace calls.

I resolve these issues by moving the freebsd and linux versions into the
relevant process plugins. In case of linux, this required adding an
interface in NativeProcessProtocol. The empty definitions on other
platforms can simply be removed.

To get the code compiling I had to add ProcessGdbRemote -> ProcessLinux
dependency, which was not caught before because we depended on it
transitively.

Zachary Turner 5c5091fcb7 [Support] Support both Windows and Posix paths on both platforms.
Previously which path syntax we supported dependend on what
platform we were compiling LLVM on.  While this is normally
desirable, there are situations where we need to be able to
handle a path that we know was generated on a remote host.
Remote debugging, for example, or parsing debug info.

99% of the code in LLVM for handling paths was platform
agnostic and literally just a few branches were gated behind
pre-processor checks, so this changes those sites to use
runtime checks instead, and adds a flag to every path
API that allows one to override the host native syntax.

Pavel Labath 7e437f8f39 Remove some ProcFileReader occurences
Summary:
ProcFileReader is the cause of the dependency from Host to ProcessLinux
module. Since it's interface is also obsolete (ReadIntoDataBuffer is
trivially replaceable by llvm::MemoryBuffer functions and
ProcessLineByLine is trivially implementable with StringRefs), instead
of moving it around I'm planning to obliterate it. This is the first
step, where I remove a couple of occurences in linux/Host.cpp, and
modernize some code around that.

I have introduced linux/Support.h, which holds two utility functions
now, whose resposibility is to construct the appropriate proc file names
-- the only useful feature of ProcFileReader.

I add a couple of tests for these functions, and for
Host::GetProcessInfo. It's worth noting that these are the first
host-specific unit tests in lldb.

Pavel Labath bf37a037d0 BreakpointResolverFileLine: Restrict move-to-nearest-code from moving across function boundaries
Summary:
This fixes the case where a user tries to set a breakpoint on a source
line outside of any function (e.g. because that code is #ifdefed out, or
the compiler did not emit code for the function, etc.) and we would
silently move the breakpoint to the next function.

Now we check whether the line range of the resolved symbol context
function matches the original line number. We reject any breakpoint
locations that appear to move the breakpoint into a new function. This
filtering only happens if we have full debug info available (e.g. in
case of -gline-tables-only compilation, we still set the breakpoint on
the nearest source line).

Pavel Labath 6de25ec61a dotest.py: remove the ability to specify different architectures/compilers in a single invocation
Summary:
This has been broken at least since the new test result framework was
added, which was over a year ago. It looks like nobody has missed it
since.

Removing this makes the gmodules handling code saner, as it already did
not know how to handle the multiple-compilers case.

My motivation for this is libc++ data formatters support on android -- I
am trying make a central way of determining whether libc++ tests can be
run, and without this, I would have to resort to similar hacks as the
gmodules code.

Chris Bieneman 1899e8d9e8 [debugserver] This is a small cleanup patch to AVX support detection
Summary:
The first Sandybridge iMacs with AVX support shipped in Spring 2011 with Snow Leopard as their OS. Unfortunately due to a kernel bug debugging AVX code was not really possible until 10.7.4.

The old code here checked the kernel build number to determine when to support AVX, but that code was incorrect. It verified that the kernel build number was greater than xnu-2020, which is the build of the kernel that had the fix for 10.8. The fix was also back ported to 10.7.4. Which means all publicly available OS builds 10.7.4 and later have working AVX support.

This new patch verifies that the host OS is greater than or equal to 10.7.4 by checking that the build number is greater than or equal to 11Exx.

The patch also removes the HasAVX assembly blob in favor of querying the kernel via sysctl for the hardware features.

Using sysctl is slower, however since the code is executed once and the result cached it is a better approach because it is possible for the kernel to disable AVX support on hardware that supports it, so listening to the kernel is a better approach for the debugger to take.

Zachary Turner d5bd3a1e6a Make file / directory completion work properly on Windows.
There were a couple of problems with this function on Windows. Different
separators and differences in how tilde expressions are resolved for
starters, but in addition there was no clear indication of what the
function's inputs or outputs were supposed to be, and there were no tests
to demonstrate its use.

To more easily paper over the differences between Windows paths,
non-Windows paths, and tilde expressions, I've ported this function to use
LLVM-based directory iteration (in fact, I would like to eliminate all of
LLDB's directory iteration code entirely since LLVM's is cleaner / more
efficient (i.e. it invokes fewer stat calls)). and llvm's portable path
manipulation library.

Since file and directory completion assumes you are referring to files and
directories on your local machine, it's safe to assume the path syntax
properties of the host in doing so, so LLVM's APIs are perfect for this.

I've also added a fairly robust set of unit tests. Since you can't really
predict what users will be on your machine, or what their home directories
will be, I added an interface called TildeExpressionResolver, and in the
unit test I've mocked up a fake implementation that acts like a unix
password database. This allows us to configure some fake users and home
directories in the test, so we can exercise all of those hard-to-test
codepaths that normally otherwise depend on the host.

This fixes two threading issues in the logging code. The access to the

Since we can log from almost any context, and we want it to be fast, so
I avoided locking primitives and used atomic variables instead. I have
also removed the (unused) setters for the mask and flags to make sure
that the only way to set them is through the enable/disable channel
functions.

I also add tests, which when run under tsan, verify that the use cases
like "doing an LLDB_LOGV while another thread disables logging" are
data-race-free.

Pavel Labath 30e6cbfcfc Revert "Use LLVM for all stat-related functionality."
this reverts r297116 because it breaks the unittests and
TestCompDirSymlink. The ModuleCache unit test is trivially fixable, but
the CompDirSymlink failure is a symptom of a deeper problem: llvm's stat
functionality is not a drop-in replacement for lldb's. The former is
based on stat(2) (which does symlink resolution), while the latter is
based on lstat(2) (which does not).

This also reverts subsequent build fixes (r297128, r297120, 297117) and
r297119 (Remove FileSpec dependency on FileSystem) which builds on top
of this.

Zachary Turner 7f6a7a3752 Remove FileSpec::ReadFileContents.
This functionality is subsumed by DataBufferLLVM, which is
also more efficient since it will try to mmap.  However, we
don't yet support mmaping writable private sections, and in
some cases we were using ReadFileContents and then modifying
the buffer.  To address that I've added a flag to the
DataBufferLLVM methods that allow you to map privately, which
disables the mmaping path entirely.  Eventually we should teach
DataBufferLLVM to use mmap with writable private, but that is
orthogonal to this effort.

In an effort to move the various DataBuffer / DataExtractor

functionality from the higher level functionality.  Only a
few functions required anything other than reading/writing
raw bytes, so those functions are separated out into a
more appropriate area.  Specifically, Dump() and DumpHexBytes()
are moved into free functions in Core/DumpDataExtractor.cpp,
and GetGNUEHPointer is moved into a static function in the
only file that it's referenced from.

Make sure we don't generate extremely long file names for test trace log
file, as this can cause path-too-long errors. As the compilers in the
android ndk are deeply nested, it's very easy to trigger these.

I chose to output at most 4 path components -- this should keep the full
path for common cases like /usr/bin/gcc with room to spare, and should
be enough to uniquely identify the compiler for more deeply nested
cases.

Pavel Labath bc58f9aa7b testsuite/android: build test executables with the android ndk directly
Summary:
This teaches the test makefiles about the Android NDK, so we are able to
run the tests without first going through the make_standalone_toolchain
script. The motivation for this is the ability to run both libc++ and
libstdc++ tests together, which previously was not possible because
make_standalone_toolchain bakes in the STL to use during toolchain
creation time. The support for this is not present yet -- this change
only make sure we don't regress for existing funcionality (gcc w/
libstdc++). Clang and libc++ support will be added later.

I've checked that the mips android targets compile after this change,
but I have no way of checking whether this breaks anything. If you are
reading this and it broke you, let me know.

Zachary Turner 3f4a4b3681 Delete DataBufferMemoryMap.
After a series of patches on the LLVM side to get the mmaping
code up to compatibility with LLDB's needs, it is now ready
to go, which means LLDB's custom mmapping code is redundant.
So this patch deletes it all and uses LLVM's code instead.

In the future, we could take this one step further and delete
even the lldb DataBuffer base class and rely entirely on
LLVM's facilities, but this is a job for another day.

Kamil Rytarowski 7a8ac3a639 Introduce support for Debug Registers in RegisterContextNetBSD_x86_64
Summary:
NetBSD 7.99.62 introduced Debug Registers interface similar to the FreeBSD one.
This interface will land NetBSD-8.0.

Introduce support for this interface in Register Context NetBSD x86_64 unconditionally as older versions of NetBSD will not be supported.

This change allows to reduce diff with other ports and remove local copy of the RegisterInfos_x86_64.h content.

NetBSD Register Context for 32-bit x86 support will be added later.

Howard Hellyer 8cfa056662 Ensure lldb-server waits for child debug servers to start up when passing them a port number to listen on.
Summary:
When lldb-server is started with the -P <port> or -m/-M <min/max port> options to specify which ports are available for remote connections the child debug server is told what port it should listen on. In those cases lldb-server needs to wait for the child to report it’s port number as otherwise it can tell the lldb client that the child is up and listening before it is actually listening on that port. lldb-server already waits in the cases where a port wasn’t specified by waiting until the child reports the port it is using. It was skipping this synchronisation step when passed a port numbers as it knew what the port would be however it does need to ensure the child process has had time to open that port and waiting until the child reports the port number makes sure this has happened.

This patch just removes the one case where a child was spawned and lldb-server did not wait for it to report it’s port number before telling the client lldb process the child is ready to connect to.

This issue was discussed on lldb-dev in a thread here:

Pavel Labath a385d2c1b6 Replace WINLOG_*** macros with LLDB_LOG
Summary:
The main difference here is that in the WINLOG macros you can specify
log categories per call, whereas here you have to go the usual lldb
route of getting a Log* variable first. While this means you have to
write at least two statements, it usually means that each statement will
fit on a single line, whereas fitting the WINLOG invocation on a single
line was almost impossible. So the total size of code does not increase
even in functions with a single log statement, and functions with more
logging get shorter.

The downside here is reduced flexibility in specifying the log
categories, which a couple of functions used quite heavily (e.g.
RefreshStateAfterStop). For these I chose a single category used most
prominently and put everything into that, although a solution with
multiple log variables is definitely possible.

Pavel Labath ba95a28c18 Log: Fix race in accessing the stream variable
Summary:
The code was attempting to copy the shared pointer member in order to
guarantee atomicity, but this is not enough. Instead, protect the
pointer with a proper read-write mutex.

This bug was present here for a long time, but my recent refactors must
have altered the timings slightly, such that now this fails fairly often
when running the tests: the test runner runs the "log disable" command
just as the thread monitoring the lldb-server child is about to report
that the server has exited.

I add a test case for this. It's not possible to reproduce the race
deterministically in normal circumstances, but I have verified that
before the fix, the test failed when run under tsan, and was running
fine afterwards.

Pavel Labath c4a3395103 Fix a couple of corner cases in NameMatches
Summary:
I originally set out to move the NameMatches closer to the relevant
function and add some unit tests. However, in the process I've found a
couple of bugs in the implementation:
- the early exits where not always correct:
  - (test==pattern) does not mean the match will always suceed because
    of regular expressions
  - pattern.empty() does not mean the match will fail because the "" is
    a valid prefix of any string

So I cleaned up those and added some tests. The only tricky part here
was that regcomp() implementation on darwin did not recognise the empty
string as a regular expression and returned an REG_EMPTY error instead.
The simples fix here seemed to be to replace the empty expression with
an equivalent non-empty one.

Michal Gorny caf810e3e4 [test] Fix finding LLDB tools when building stand-alone
Use both LLDB- and LLVM-specific tool/library directories when LLDB is
being built stand-alone. This ensures that the freshly-built tools
(and libraries) are used correctly.

Without this patch, the test suite uses LLVM_TOOLS_DIR and LLVM_LIBS_DIR
to locate lldb, and set PATH and LD_LIBRARY_PATH. When doing
a stand-alone build, these variables represent the installed LLVM.
As a result, tests either fail due to missing lldb executable
or use an earlier installed LLDB version rather than the one being
built.

To solve this, additional LLDB_TOOLS_DIR and LLDB_LIBS_DIR variables
are added and populated using LLVM_*_OUTPUT_INTDIR. Those variables
contain directories used to output built executables and libraries.
In stand-alone builds, they represent the build-tree directories
used by LLDB. In integrated builds, they have the same values as
LLVM_*_DIR and therefore using them does not harm.

The new variables are prepended to PATH and LD_LIBRARY_PATH to ensure
that freshly built binaries are preferred over potentially earlier
installed ones. Furthermore, paths used to locate various tools are
updated to match appropriate locations.

The testsuite's results formatter maintains a result_status_counts

result_events structure that contains the results of individual
tests.

There are subtle bugs arising from this redundancy that make some
builds report no errors but a nonzero status.  Rather than try to
make sure these two are always in agreement, I've just rewritten
the code that used to use the counts to now use the per-test
results.

Pavel Labath a37bbbd432 NPL: Fix one more bug in the single step workaround
In the case we are stepping over the thread creation instruction, we
will end up calling Thread::SingleStep back-to-back twice (because of
the intermediate PTRACE_EVENT_CLONE stop). This will cause the cpu mask
to be set inappropriately (because the old SingleStepCheck object will
be destroyed after we create the new one), and the single-step will
fail.

Before the refactor the code was still incorrect in this case, but in a
different way (the thread was left with the incorrect mask after the
stepping was complete), so this was not easy to spot.

This fixes TestCreateDuringInstructionStep on the affected devices.

Pavel Labath 5fb8af40df Refactor log channel registration mechanism
Summary:
We currently have two log channel registration mechanisms. One uses a
set of function pointers and the other one is based on the
PluginManager.

The PluginManager dependency is unfortunate, as logging
is also used in lldb-server, and the PluginManager pulls in a lot of
classes which are not used in lldb-server.

Both approach have the problem that they leave too much to do for the
user, and so the individual log channels end up reimplementing command
line argument parsing, category listing, etc.

Here, I replace the PluginManager-based approach with a one. The new API
is more declarative, so the user only needs to specify the list of list
of channels, their descriptions, etc., and all the common tasks like
enabling/disabling categories are hadled by common code. I migrate the
LogChannelDWARF (only user of the PluginManager method) to the new API.

In the follow-up commits I'll replace the other channels with something
similar.
