Now that the Xcode project is removed, I want to focus on dotest as a

rely on llvm's lit. Removing multiprocessing is the first step in that
direction.

The run command is only an abbreviation for the more verbose process
launch -- <args> but it works just as with GDB and therefore should be
mentioned in the GDB to LLDB command map.

For educational purposes I've not listed it as the first option on the
LLDB side so that new LLDB user can, if they want, also know what the
"native" way is for LLDB.

Here's the help documentation for the run command in lldb which gives
proof:

> (lldb) help run
>      Launch the executable in the debugger.
>
> Syntax: run [<run-args>]
>
> Command Options Usage:

Adrian Prantl 0e4c482124 Pass ConstString by value (NFC)
My apologies for the large patch. With the exception of ConstString.h
itself it was entirely produced by sed.

ConstString has exactly one const char * data member, so passing a
ConstString by reference is not any more efficient than copying it by
value. In both cases a single pointer is passed. But passing it by
value makes it harder to accidentally return the address of a local
object.

Jonas Devlieghere edb874b231 Add LLDB website and documentation in reStructuredText for Sphinx
The current LLDB website is written in HTML which is hard to maintain.
We have quite a bit of HTML code checked in which can make it hard to
differentiate between documentation written by us and documentation
generated by a tool.

In line with the other LLVM projects, I propose generating the
documentation with Sphix. I think text/rst files provide a lower barrier
for new or casual contributors to fix or update.

This patch adds a copy of the LLDB website and documentation in
reStructuredText. It also adds a new ninja target `docs-lldb-html` when
-DLLVM_ENABLE_SPHINX:BOOL is enabled.

This is the first step in having the website and documentation being
generated from the repository, rather than having the output checked-in
under the www folder. During the hopefully short transition period,
please also update the reStructuredText files when modifying the
website.

Adrian Prantl 5ec76fe720 Compile the LLDB tests out-of-tree.
This patch is the result of a discussion on lldb-dev, see
http://lists.llvm.org/pipermail/lldb-dev/2018-January/013111.html for
background.

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
patch in order to get the bots green again. We will likely have to
iterate on this some more.

Vedant Kumar 3c3345be1b [CMake] Make check-lldb work with LLDB_CODESIGN_IDENTITY=''
On Darwin, if a test machine isn't set up for code-signing (see
docs/code-signing.txt), running check-lldb should use the system
debugserver instead of the unsigned one built in-tree. This makes it
possible to run lldb's test suite without having code-signing set up,
which is really convenient.

Pavel Labath 2f1fbaebe2 gdb-remote: Add jModulesInfo packet
Summary:
This adds the jModulesInfo packet, which is the equivalent of qModulesInfo, but it enables us to
query multiple modules at once. This makes a significant speed improvement in case the
application has many (over a hundred) modules, and the communication link has a non-negligible
latency. This functionality is accessed by ProcessGdbRemote::PrefetchModuleSpecs(), which does
the caching. GetModuleSpecs() is modified to first consult the cache before asking the remote
stub. PrefetchModuleSpecs is currently only called from POSIX-DYLD dynamic loader plugin, after
it reads the list of modules from the inferior memory, but other uses are possible.

This decreases the attach time to an android application by about 40%.

"Incorrect" file name seen on Android whene the main executable is
called "app_process32" (or 64) but the linker specifies the package
name (e.g. com.android.calculator2). Additionally it can be present
in case of some linker bugs.

This CL adds logic to try to fetch the correct file name from the proc
file system based on the base address sepcified by the linker in case
we are failed to load the module by name.

Jason Molenda 7e9bd599a2 Add a new "thread-pcs" key-value pair to the T packet response from
debugserver.  thread-pcs has a comma separated list of base 16
addresses - the current pc value for every thread in the process.
It is a partner of the "threads:" key where a list of thread IDs
is given.  The pc values in thread-pcs correspond one-to-one with
the thread IDs in the threads list.

This is a part of performance work.  When lldb is instruction
stepping / fast stepping over a range of addresses for e.g. a "next"
command, and it steps in to another function, lldb will put a
breakpoint on the return address and continue the process.  Before
it calls continue, it calls Thread::SetupForResume on all the
threads, and SetupForResume needs to get the current pc value for
every thread to see if any are at a breakpoint site.

The result is that issuing a "c" continue requires that we send
"read pc register" packets for every thread.

We may do this sequence of step-into-function / continue-to-get-out
many times for a single user-visible "next" or "step" command, and
with highly multithreaded programs, we are sending many extra
packets to get all the thread values.

I looked at including this data in the "jstopinfo" JSON that
we already have in the T packet.  But there are three problems that
would make this increase the size of the T packet significantly.
First, numbers in JSON are base 10.  Second, a proper JSON would
have something like "thread_pcs": { "34224331112":383772734222, ...}
for thread-id 34224331112 and pc 383772734222 - so we're including
a whole extra copy of the thread id in addition to the pc.  Third,
the JSON text is hex-ascii'fied so the size of it is doubled.
In one example, 

threads:585db8,585dc7,585dc8,585dc9,585dca,585dce;thread-pcs:100001400,7fff8badc6de,7fff8badcff6,7fff8badc6de,7fff8badc6de,7fff8badc6de;

The "thread-pcs" adds 86 characters - 136 characters for both 
threads and thread-pcs.  Doing this in JSON would look like

threads={"5791160":4294972416,"5791175":140735536809694,"5791176":140735536812022,"5791177":140735536809694,"5791178":140735536809694,"5791182":140735536809694}

or 160 characters -- or 320 characters once it is hex-asciified.

Given that it's 86 characters vrs 320, I went with the old style
approach.  I've seen real world programs that have up to 60 threads
in them, so this could result in vastly larger packets if it
was all done in the JSON with hex-ascii expansion.

If we had an all-JSON T packet, where we didn't need to hex-ascii
encode anything, that would have been the better approach.  But
we'd already have a list of threads in JSON at that point so
the additional text wouldn't be too bad.

I'm working on finishing the patches to lldb to use this data;
will commit those once I've had a chance to test them more.  But
I wanted to commit the debugserver bits which are more
straightforward.

Tamas Berghammer ccd6cffba3 Modify "platform connect" to connect to processes as well
The standard remote debugging workflow with gdb is to start the
application on the remote host under gdbserver (e.g.: gdbserver :5039
a.out) and then connect to it with gdb.

The same workflow is supported by debugserver/lldb-gdbserver with a very
similar syntax but to access all features of lldb we need to be
connected also to an lldb-platform instance running on the target.

Before this change this had to be done manually with starting a separate
lldb-platform on the target machine and then connecting to it with lldb
before connecting to the process.

This change modifies the behavior of "platform connect" with
automatically connecting to the process instance if it was started by
the remote platform. With this command replacing gdbserver in a gdb
based worflow is usually as simple as replacing the command to execute
gdbserver with executing lldb-platform.

Jason Molenda 20ee21bde6 Add a another packet to the gdb-remote protocol,
jGetLoadedDynamicLibrariesInfos.  This packet is similar to
qXfer:libraries:read except that lldb supplies the number of solibs
that should be reported about, and the start address for the list
of them.  At the initial process launch we'll read the full list
of solibs linked by the process -- at this point we could be using
qXfer:libraries:read -- but on subsequence solib-loaded notifications,
we'll be fetching a smaller number of solibs, often only one or two.

A typical Mac/iOS GUI app may have a couple hundred different 
solibs loaded  - doing all of the loads via memory reads takes 
a couple of megabytes of traffic between lldb and debugserver.
Having debugserver summarize the load addresses of all the solibs
and sending it in JSON requires a couple of hundred kilobytes
of traffic.  It's a significant performance improvement when 
communicating over a slower channel.

This patch leaves all of the logic for loading the libraries
in DynamicLoaderMacOSXDYLD -- it only call over ot ProcesGDBRemote
to get the JSON result.

If the jGetLoadedDynamicLibrariesInfos packet is not implemented,
the normal technique of using memory read packets to get all of
the details from the target will be used.

Jason Molenda 91ffe0a570 Add a new wart, I mean feature, on to gdb-remote protocol: compression.
For some communication channels, sending large packets can be very 
slow.  In those cases, it may be faster to compress the contents of
the packet on the target device and decompress it on the debug host
system.  For instance, communicating with a device using something
like Bluetooth may be an environment where this tradeoff is a good one.

This patch adds a new field to the response to the "qSupported" packet
(which returns a "qXfer:features:" response) -- SupportedCompressions
and DefaultCompressionMinSize.  These tell you what the remote
stub can support.

lldb, if it wants to enable compression and can handle one of those 
algorithms, it can send a QEnableCompression packet specifying the
algorithm and optionally the minimum packet size to use compression
on.  lldb may have better knowledge about the best tradeoff for
a given communication channel.

I added support to debugserver an lldb to use the zlib APIs
(if -DHAVE_LIBZ=1 is in CFLAGS and -lz is in LDFLAGS) and the
libcompression APIs on Mac OS X 10.11 and later 
(if -DHAVE_LIBCOMPRESSION=1).  libz "zlib-deflate" compression.
libcompression can support deflate, lz4, lzma, and a proprietary
lzfse algorithm.  libcompression has been hand-tuned for Apple
hardware so it should be preferred if available.

debugserver currently only adds the SupportedCompressions when
it is being run on an Apple watch (TARGET_OS_WATCH).  Comment
that #if out from RNBRemote.cpp if you want to enable it to
see how it works.  I haven't tested this on a native system
configuration but surely it will be slower to compress & decompress
the packets in a same-system debug session.

I haven't had a chance to add support for this to 
GDBRemoteCommunciationServer.cpp yet.

Chandler Carruth 875d3bb538 [cmake/multilib] Teach LLDB to respect the multlib LLVM_LIBDIR_SUFFIX
variable (now provided both by the normal parent LLVM CMake files and by
the LLVMConfig.cmake file used by the standalone build).

This allows LLDB to build into and install into correctly suffixed
libdirs. This is especially significant for LLDB because the python
extension building done by CMake directly uses multilib suffixes when
the host OS does, and the host OS will not always look back and forth
between them. As a consequence, before LLVM, Clang, and LLDB (and every
other subproject) had support for using LLVM_LIBDIR_SUFFIX, you couldn't
build or install LLDB on a multilib system with its python extensions
enabled. With this patch (on top of all the others I have submitted
throughout the project), I'm finally able to build and install LLDB on
my system with Python support enabled. I'm also able to actually run the
LLDB test suite, etc. Now, a *huge* number of the tests still fail on my

ArchSpec now contains an optional distribution_id, with getters and

The gdb remote qHostInfo message transmits it, if set, via the

reflect this change.

As before, GetDistributionId () returns nothing on non-Linux platforms
at this time. On Linux, it is returned only if the lsb_platform
command is installed (in /bin or /usr/bin), and only if the
distributor id key is returned by 'lsb_platform -i'. This id is
lowercased, and whitespace is replaced with underscores.

    Verified the test suite runs cleanly on Linux (x86_64), build OK on Mac OS
    X Mountain Lion.

    Additional improvements (not in the source SVN branch 'lldb-platform-work'):
    - cmake build scripts for lldb-platform
    - cleanup test suite
    - documentation stub for qPlatform_RunCommand
    - use log class instead of printf() directly
    - reverted work-in-progress-looking changes from test/types/TestAbstract.py that work towards running the test suite remotely.
    - add new logging category 'platform'

Jason Molenda f17b5ac6e1 <rdar://problem/11961650>
Update the debugserver "qProcessInfo" implementation to return the
cpu type, cpu subtype, OS and vendor information just like qHostInfo
does so lldb can create an ArchSpec based on the returned values.

Add a new GetProcessArchitecture to GDBRemoteCommunicationClient akin
to GetHostArchitecture.  If the qProcessInfo packet is supported,
GetProcessArchitecture will return the cpu type / subtype of the 
process -- e.g. a 32-bit user process running on a 64-bit x86_64 Mac
system. 

Have ProcessGDBRemote set the Target's architecture based on the 
GetProcessArchitecture when we've completed an attach/launch/connect.

llvm-svn: 170491
2012-12-19 02:54:03 +00:00
Jason Molenda fca9c6bb9f Add a new qProcessInfo packet to debugserver.
This can be used by lldb to ask for information
about the process debugserver is attached to/launched.
Particularly useful on a 64-bit x86 Mac system which
can run  32-bit or 64-bit user-land processes.

Jason Molenda cb349ee19c When unwinding from the first frame, try to ask the remote debugserver
if this is a mapped/executable region of memory.  If it isn't, we've jumped
through a bad pointer and we know how to unwind the stack correctly based
on the ABI.  

Previously I had 0x0 special cased but if you jumped to 0x2 on x86_64 one
frame would be skipped because the unwinder would try using the x86_64 
ArchDefaultUnwindPlan which relied on the rbp.
