Ilia K b792be8e79 Fix -data-list-register-names/-data-disassemble, minor fix in -data-list-register-values (MI)
Summary:
* Fix -data-list-register-names command: previously it ignored regno arguments and always showed all registers
* Add 'size' field to -data-disassemble command: now we are able to get an instruction's size
* Minor fix in -data-list-register-value: fix comments/code style
* Enable all tests in MiDataTestCase
* Fix the GetRegister function that gets an register by its index

These changes were tested on OS X; all MiDataTestCase tests were passed.

Hafiz Abid Qadeer 94e222f943 Fix a typo.
The member m_nTimes is used in rest of lldb-mi to represent hit count.
In one place, it was assigned a wrong value (number of locations). This
resulted in lldb-mi showing a hit count of variable 1 when it was created.

Hafiz Abid Qadeer d1f606ff0f Fix a race condition in lldb-mi.
lldb-mi has 3 threads.
1. One that waits for user intput.
2. Another waits for 1st thread to get input command.
3. Waits for events from lldb.

2 & 3 needs to be synchronized so that they don't end up
doing things at same time. For example, while "break insert" is
processing, we can get a breakpoint event. Depending on where we
are in "break-insert", it can have different behavior. In some
cases, it can cause breakpoint to be deleted too. I have added a 
mutex so that command processing and event processing are done 
exclusively and they are not running at the same time.

In longer term, I think thread 2 & 3 should be merged to be only 
one thread which can wait on command or events.

Hafiz Abid Qadeer 9a0d572750 Restore the signal handler for Windows as it is not presistent there.
On windows, signal handler is reset to default once a signal is received. 
This causes doing ctrl-c twice on console (or pressing suspend button twice
in eclipse ide which uses SIGINT to stop the debuggee) to crash lldb-mi on 
windows. Although there is very tiny window (after signal handler is called
and before we restore the handler) where default handler will be in place.
But this is hardly a problem in practice as IDEs generally disable their suspend
button once it has been presses.

Hafiz Abid Qadeer 0d51c1563b Fix CLI commands in lldb-mi.
This patch fixes execution of CLI commands in MI mode. The CLI commands are 
executed using "-interpreter-exec" command. The bug was in the 
CMICmnLLDBDebugSessionInfo class which contained the following members: 
SBProcess, SBTarget, SBDebugger and SBListener, but CLI commands don't affect
them and they aren't updated. Therefore some members can contain incorrect 
(or obsolete) reference and it can cause an error. My patch removes these 
members and uses getters that provides the updated instance every time it is used.

Hafiz Abid Qadeer 6a4ea636f3 Fix log file generation in lldb-mi.
When it runs, lldb-mi creates a log file. There is an option --noLog
to disable the creation but it does not work and you end up with log 
file. This happens as log is enabled in a few places in the code 
although it has been disabled by this option.

This commit tried to fix the problem in the following way.

Log file generation is disabled by default.
You can enable it by giving --log option. It is the only way to enable
it. Rest of the call have been removed.

So the code basically remove the calls that enable the log 
unconditionally and changes the option --noLog to --log.

Hafiz Abid Qadeer fcbc3cdf3c Replace ioctl with select to reduce processor usage by lldb-mi on OSX.
This saga started with a hang on OSX. 2 solutions were proposed.
1) 'select' based solution works ok on OSX but slows down test completion time
on Linux many times.
2) 'ioctl' base solution also works but it causes heavy processor usage on OSX
as reported by Ilia K.

But as the original hang did not occur on Linux so this commit re-introduces the
'select' in conditional code so that it only runs for OSX. There is no need for
this 'fix' to run on Linux.

Greg Clayton a97c4d2154 Handle thumb IT instructions correctly all the time.
The issue with Thumb IT (if/then) instructions is the IT instruction preceeds up to four instructions that are made conditional. If a breakpoint is placed on one of the conditional instructions, the instruction either needs to match the thumb opcode size (2 or 4 bytes) or a BKPT instruction needs to be used as these are always unconditional (even in a IT instruction). If BKPT instructions are used, then we might end up stopping on an instruction that won't get executed. So if we do stop at a BKPT instruction, we need to continue if the condition is not true.

When using the BKPT isntructions are easy in that you don't need to detect the size of the breakpoint that needs to be used when setting a breakpoint even in a thumb IT instruction. The bad part is you will now always stop at the opcode location and let LLDB determine if it should auto-continue. If the BKPT instruction is used, the BKPT that is used for ARM code should be something that also triggers the BKPT instruction in Thumb in case you set a breakpoint in the middle of code and the code is actually Thumb code. A value of 0xE120BE70 will work since the lower 16 bits being 0xBE70 happens to be a Thumb BKPT instruction. 

The alternative is to use trap or illegal instructions that the kernel will translate into breakpoint hits. On Mac this was 0xE7FFDEFE for ARM and 0xDEFE for Thumb. The darwin kernel currently doesn't recognize any 32 bit Thumb instruction as a instruction that will get turned into a breakpoint exception (EXC_BREAKPOINT), so we had to use the BKPT instruction on Mac. The linux kernel recognizes a 16 and a 32 bit instruction as valid thumb breakpoint opcodes. The benefit of using 16 or 32 bit instructions is you don't stop on opcodes in a IT block when the condition doesn't match. 

To further complicate things, single stepping on ARM is often implemented by modifying the BCR/BVR registers and setting the processor to stop when the PC is not equal to the current value. This means single stepping is another way the ARM target can stop on instructions that won't get executed.

This patch does the following:
1 - Fix the internal debugserver for Apple to use the BKPT instruction for ARM and Thumb
2 - Fix LLDB to catch when we stop in the middle of a Thumb IT instruction and continue if we stop at an instruction that won't execute
3 - Fixes this in a way that will work for any target on any platform as long as it is ARM/Thumb
4 - Adds a patch for ignoring conditions that don't match when in ARM mode (see below)

This patch also provides the code that implements the same thing for ARM instructions, though it is disabled for now. The ARM patch will check the condition of the instruction in ARM mode and continue if the condition isn't true (and therefore the instruction would not be executed). Again, this is not enable, but the code for it has been added.

Jason Molenda e589e7e336 The lldb unwinder can now use the unwind information from the compact-unwind
section for x86_64 and i386 targets on Darwin systems.  Currently only the
compact unwind encoding for normal frame-using functions is supported but it
will be easy handle frameless functions when I have a bit more free time to
test it.  The LSDA and personality routines for functions are also retrieved
correctly for functions from the compact unwind section.

This new code is very fresh -- it passes the lldb testsuite and I've done
by-hand inspection of many functions and am getting correct behavior for all
of them.  There may need to be some bug fixing over the next couple weeks as
I exercise and test it further.  But I think it's fine right now so I'm
committing it.

the sequence is encoded in a variable base number.  Added some
comments with references to what the code is doing so it'll be

UNWIND_X86_64_MODE_STACK_IMMD and UNWIND_X86_64_MODE_STACK_IND

Only x86_64 is supported right now.  Given that this is an
experiment in parsing the section contents, I don't expect to
add other architectures; they are trivial variations on this
arch.  There exists a real dumper included in the Xcode tools,

Jim Ingham ffc9f1de34 This adds a "batch mode" to lldb kinda like the gdb batch mode. It will quit the debugger
after all the commands have been executed except if one of the commands was an execution control
command that stopped because of a signal or exception.

Also adds a variant of SBCommandInterpreter::HandleCommand that takes an SBExecutionContext.  That
way you can run an lldb command targeted at a particular target, thread or process w/o having to 
select same before running the command.

Also exposes CommandInterpreter::HandleCommandsFromFile to the SBCommandInterpreter API, since that
seemed generally useful.

Change the way the "-o" options to the lldb driver are processed so:
1) They are run synchronously - didn't really make any sense to run the asynchronously.

Todd Fiala eeb023cf76 Fix codesigning of MacOSX debugserver when built with cmake.
This patch fixes the codesigning of debugserver on OSX when built with
cmake.  Without this you get this error when debugging:
    error: process launch failed: unable to locate debugserver

Note: you also need to set LLDB_DEBUGSERVER_PATH to point to your built debugserver.
e.g. export LLDB_DEBUGSERVER_PATH=`pwd`/bin/debugserver

Change by dawn@burble.org.

Saleem Abdulrasool 9e5b49831c driver: handle write error better
We would previously simply assume that the write would always succeed.  However,
write(2) may return -1 for error as well as fail to perform a complete write (in
which case the returned number of bytes will be less than the requested bytes).

Explicitly check if an error condition is encountered.  This would previously
not be caught as we default initialized success to true.  Add an assertion that
we always perform a complete write (a continuous retry could be added to ensure
that we finish writing completely).

This was caught by GCC's signed comparison warning and manual inspection.

Todd Fiala 737f43628a llgs: remove all Initialize() calls except for Debugger::Initialize().
See thread here:
http://lists.cs.uiuc.edu/pipermail/lldb-commits/Week-of-Mon-20140825/012580.html

The original change I made there was due to a segfault.  That was
caused by me directly calling PluginManager::Initialize (), with
PluginManager::Initialize() depending on HostInfo::Initialize () to
have been called already (which it wasn't).

The call to PluginManager::Initialize () was erroneous (at least at the 
current time) since that method is already called by Debugger::Initialize()'s 
implementation.

We will want to revisit initializing a smaller core of the debugger
suitable for lldb-gdbserver and lldb-platform.

Todd Fiala af245d115b Add lldb-gdbserver support for Linux x86_64.
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.

Jason Molenda 705b180964 Initial merge of some of the iOS 8 / Mac OS X Yosemite specific
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) 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.

Greg Clayton 7ab7f89ae0 iOS simulator cleanup to make sure we use "*-apple-ios" for iOS simulator apps and binaries.
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

Todd Fiala ff6131a958 Add support for gdb remote $X stop notification.
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.

Deepak Panickal 6f9c468102 Initial commit of LLDB Machine Interface Frontend.
- Tested with Eclipse, likely to work with other GDB/MI compatible GUIs.
- Some but not all MI commands have been implemented. See MIReadme.txt for more info.
- Written from scratch, no GPL code, based on LLDB Public API.
- Built for Linux, Windows and OSX. Tested on Linux and Windows.

Todd Fiala 9f72b3a1ce Modify debugserver to follow gdb remote $qC protocol definition.
$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).

Todd Fiala 71afe0b1d5 Make lldb-gdbserver configure/(g)make build parity with cmake.
This now builds lldb-gdbserver on all Linux and FreeBSD architectures
rather than being locked to x86_64 architectures only.

Please note lldb-gdbserver is not yet functional, this just enables
the non-x86_64 Linux/FreeBSD build using the configure/make build
system.

Jason Molenda a332978b2a lldb arm64 import.
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.
