to the remote side (QStartNoAckMode) - it may take a little longer
than normal to get a reply.
In debugserver, hardcode the priority for several threads so they
aren't de-prioritized when a user app is using system resources.
Also, set the names of the threads.

This change brings in lldb-gdbserver (llgs) specifically for Linux x86_64.
(More architectures coming soon).
Not every debugserver option is covered yet. Currently
the lldb-gdbserver command line can start unattached,
start attached to a pid (process-name attach not supported yet),
or accept lldb attaching and launching a process or connecting
by process id.
The history of this large change can be found here:
https://github.com/tfiala/lldb/tree/dev-tfiala-native-protocol-linux-x86_64
Until mid/late April, I was not sharing the work and continued
to rebase it off of head (developed via id tfiala@google.com). I switched over to
user todd.fiala@gmail.com in the middle, and once I went to github, I did
merges rather than rebasing so I could share with others.

Elevate ProcessInfo and ProcessLaunchInfo into their own headers.
llgs will be using ProcessLaunchInfo but doesn't need to pull in
the rest of Process.h.
This also moves a bunch of implementation details from the header
declarations into ProcessInfo.cpp and ProcessLaunchInfo.cpp.
Tested on Ubuntu 14.04 Cmake and MacOSX Xcode.
Related to https://github.com/tfiala/lldb/issues/26.

Replace adhoc inline implementation of llvm::array_lengthof in favour of the
implementation in LLVM. This is simply a cleanup change, no functional change
intended.

process fully reaped. The race & bad behavior was because we were letting
the reaping thread in LLDB to also set the Process exit status, so debugserver
would sometimes be shut down before it got a chance to report the exit status,
and then we got confused.

Building OS X debugserver assumes you have an Xcode installation at /Application/Xcode.app. Let's instead detect where Xcode is using xcrun.

lldb support. I'll be doing more testing & cleanup but I wanted to
get the initial checkin done.
This adds a new SBExpressionOptions::SetLanguage API for selecting a
language of an expression.
I added adds a new SBThread::GetInfoItemByPathString for retriving
information about a thread from that thread's StructuredData.
I added a new StructuredData class for representing
key-value/array/dictionary information (e.g. JSON formatted data).
Helper functions to read JSON and create a StructuredData object,
and to print a StructuredData object in JSON format are included.
A few Cocoa / Cocoa Touch data formatters were updated by Enrico
to track changes in iOS 8 / Yosemite.
Before we query a thread's extended information, the system runtime may
provide hints to the remote debug stub that it will use to retrieve values
out of runtime structures. I added a new SystemRuntime method
AddThreadExtendedInfoPacketHints which allows the SystemRuntime to add
key-value type data to the initial request that we send to the remote stub.
The thread-format formatter string can now retrieve values out of a thread's
extended info structured data. The default thread-format string picks up
two of these - thread.info.activity.name and thread.info.trace_messages.
I added a new "jThreadExtendedInfo" packet in debugserver; I will
add documentation to the lldb-gdb-remote.txt doc soon. It accepts
JSON formatted arguments (most importantly, "thread":threadnum) and
it returns a variety of information regarding the thread to lldb
in JSON format. This JSON return is scanned into a StructuredData
object that is associated with the thread; UI layers can query the
thread's StructuredData to see if key-values are present, and if
so, show them to the user. These key-values are likely to be
specific to different targets with some commonality among many
targets. For instance, many targets will be able to advertise the
pthread_t value for a thread.
I added an initial rough cut of "thread info" command which will print
the information about a thread from the jThreadExtendedInfo result.
I need to do more work to make this format reasonably.
Han Ming added calls into the pmenergy and pmsample libraries if
debugserver is run on Mac OS X Yosemite to get information about the
inferior's power use.
I added support to debugserver for gathering the Genealogy information
about threads, if it exists, and returning it in the jThreadExtendedInfo
JSON result.

(lldb) file /bin/ls
(lldb) b malloc
(lldb) run
(lldb) process save-core /tmp/ls.core
Each ObjectFile plug-in now has the option to save core files by registering a new static callback.
llvm-svn: 210864
Changes include:
- ObjectFileMachO can now determine if a binary is "*-apple-ios" or "*-apple-macosx" by checking the min OS and SDK load commands
- ArchSpec now says "<arch>-apple-macosx" is equivalent to "<arch>-apple-ios" since the simulator mixes and matches binaries (some from the system and most from the iOS SDK).
- Getting process inforamtion on MacOSX now correctly classifies iOS simulator processes so they have "*-apple-ios" architectures in the ProcessInstanceInfo
- PlatformiOSSimulator can now list iOS simulator processes correctly instead of showing nothing by using:
(lldb) platform select ios-simulator
(lldb) platform process list
- debugserver can now properly return "*-apple-ios" for the triple in the process info packets for iOS simulator executables
- GDBRemoteCommunicationClient now correctly passes along the triples it gets for process info by setting the OS in the llvm::Triple correctly

Need to spend a little more time with suppressing the debugserver 64-to-32 bit warnings.
Will re-submit after I get the warnings properly suppressed.
llvm-svn: 209151
debugserver now returns $X09 as the immediate response to
a $k kill process request rather than $W09.
ProcessGDBRemote now properly handles X as indication of
a process exit state.
The @debugserver_test and @lldb_test for $k now properly expects
an X notification (signal-caused exit) after killing a just-attached
inferior that was still in the stopped state.
llvm-svn: 209108
$qC from debugserver now returns the current thread's thread-id (and, like $?, will set a current thread if one is not already selected). Previously it was returning the current process id.
lldb will now query $qProcessInfo to retrieve the process id. The process id is now cached lazily and reset like other cached values. Retrieval of the process id will fall back to the old $qC method for vendor==Apple and os==iOS if the qProcessInfo retrieval fails.
Added a gdb remote protocol-level test to verify that $qProcessInfo reports a valid process id after launching a process, while the process is in the initial stopped state. Verifies the given process id is a currently valid process on host OSes for which we know how to check (MacOSX, Linux, {Free/Net}BSD). Ignores the live process check for OSes where we don't know how to do this. (I saw no portable way to do this in stock Python without pulling in other libs).

These changes were written by Greg Clayton, Jim Ingham, Jason Molenda.
It builds cleanly against TOT llvm with xcodebuild. I updated the
cmake files by visual inspection but did not try a build. I haven't
built these sources on any non-Mac platforms - I don't think this
patch adds any code that requires darwin, but please let me know if
I missed something.
In debugserver, MachProcess.cpp and MachTask.cpp were renamed to
MachProcess.mm and MachTask.mm as they picked up some new Objective-C
code needed to launch processes when running on iOS.

condition where we could end up killing debugserver (and thus the target) before it had a chance
to detach.
Also fix debugserver to send the OK AFTER it detaches to avoid the same race condition.

Also fix the bug where lldb prints: "Got a connection and launched debugserver" rather
than the name of the process it actually launched.

This change does the following:
* Adds Makefile build scripts to debug server.
* Fixes a few small mistakes in the other makefiles.
* Modifies generate-vers.pl slightly to also work for debugserver.
* Changes the OS X, non-framework python search path from libdir to
libdir/python2.X/site-packages where it is installed by the build
system (also where it is installed on other operating systems).
Patch by Keno Fischer.
