LLDB is crashing when logging is enabled from lldb-perf-clang. This has to do with the global destructor chain as the process and its threads are being torn down.

All logging channels now make one and only one instance that is kept in a global pointer which is never freed. This guarantees that logging can correctly continue as the process tears itself down.

7d4083837c5a258375fdc185d464b4ed15759a4b 02-Mar-2013 Jim Ingham <jingham@apple.com> Convert from the C-based LLVM Disassembler shim to the full MC Disassembler API's.
Calculate "can branch" using the MC API's rather than our hand-rolled regex'es.
As extra credit, allow setting the disassembly flavor for x86 based architectures to intel or att.

1b584ebc1de8b50fe375cffb5fb33ad13be10046 05-May-2012 Jim Ingham <jingham@apple.com> Don't expose the pthread_mutex_t underlying the Mutex & Mutex::Locker classes.
No one was using it and Locker(pthread_mutex_t *) immediately asserts for
pthread_mutex_t's that don't come from a Mutex anyway. Rather than try to make
that work, we should maintain the Mutex abstraction and not pass around the
platform implementation...

Make Mutex::Locker::Lock take a Mutex & or a Mutex *, and remove the constructor
taking a pthread_mutex_t *. You no longer need to call Mutex::GetMutex to pass
your mutex to a Locker (you can't in fact, since I made it private.)

Cleaned up the Mutex::Locker and the ReadWriteLock classes a bit.

Also cleaned up the GDBRemoteCommunication class to not have so many packet functions. Used the "NoLock" versions of send/receive packet functions when possible for a bit of performance.

This fix really needed to happen as a previous fix I had submitted for
calculating symbol sizes made many symbols appear to have zero size since
the function that was calculating the symbol size was calling another function
that would cause the calculation to happen again. This resulted in some symbols
having zero size when they shouldn't. This could then cause infinite stack
traces and many other side affects.

I started work on being able to add symbol files after a debug session
had started with a new "target symfile add" command and quickly ran into
problems with stale Address objects in breakpoint locations that had
lldb_private::Section pointers into modules that had been removed or
replaced. This also let to grabbing stale modules from those sections.
So I needed to thread harded the Address, Section and related objects.

To do this I modified the ModuleChild class to now require a ModuleSP
on initialization so that a weak reference can created. I also changed
all places that were handing out "Section *" to have them hand out SectionSP.
All ObjectFile, SymbolFile and SymbolVendors were inheriting from ModuleChild
so all of the find plug-in, static creation function and constructors now
require ModuleSP references instead of Module *.

Address objects now have weak references to their sections which can
safely go stale when a module gets destructed.

This checkin doesn't complete the "target symfile add" command, but it
does get us a lot clioser to being able to do such things without a high
risk of crashing or memory corruption.

334d33a19fd28cf41cba74cc61cf149e7101a603 30-Jan-2012 Greg Clayton <gclayton@apple.com> SBFrame is now threadsafe using some extra tricks. One issue is that stack
frames might go away (the object itself, not the actual logical frame) when
we are single stepping due to the way we currently sometimes end up flushing
frames when stepping in/out/over. They later will come back to life
represented by another object yet they have the same StackID. Now when you get
a lldb::SBFrame object, it will track the frame it is initialized with until
the thread goes away or the StackID no longer exists in the stack for the
thread it was created on. It uses a weak_ptr to both the frame and thread and
also stores the StackID. These three items allow us to determine when the
stack frame object has gone away (the weak_ptr will be NULL) and allows us to
find the correct frame again. In our test suite we had such cases where we
were just getting lucky when something like this happened:

1 - stop at breakpoint
2 - get first frame in thread where we stopped
3 - run an expression that causes the program to JIT and run code
4 - run more expressions on the frame from step 2 which was very very luckily
still around inside a shared pointer, yet, not part of the current
thread (a new stack frame object had appeared with the same stack ID and
depth).

We now avoid all such issues and properly keep up to date, or we start
returning errors when the frame doesn't exist and always responds with
invalid answers.

Also fixed the UserSettingsController (not going to rewrite this just yet)
so that it doesn't crash on shutdown. Using weak_ptr's came in real handy to
track when the master controller has already gone away and this allowed me to
pull out the previous NotifyOwnerIsShuttingDown() patch as it is no longer
needed.

13d24fb1817faa7ccc4cfd799113ba1a2b8968eb 29-Jan-2012 Greg Clayton <gclayton@apple.com> Switching back to using std::tr1::shared_ptr. We originally switched away
due to RTTI worries since llvm and clang don't use RTTI, but I was able to
switch back with no issues as far as I can tell. Once the RTTI issue wasn't
an issue, we were looking for a way to properly track weak pointers to objects
to solve some of the threading issues we have been running into which naturally
led us back to std::tr1::weak_ptr. We also wanted the ability to make a shared
pointer from just a pointer, which is also easily solved using the
std::tr1::enable_shared_from_this class.

The main reason for this move back is so we can start properly having weak
references to objects. Currently a lldb_private::Thread class has a refrence
to its parent lldb_private::Process. This doesn't work well when we now hand
out a SBThread object that contains a shared pointer to a lldb_private::Thread
as this SBThread can be held onto by external clients and if they end up
using one of these objects we can easily crash.

So the next task is to start adopting std::tr1::weak_ptr where ever it makes
sense which we can do with lldb_private::Debugger, lldb_private::Target,
lldb_private::Process, lldb_private::Thread, lldb_private::StackFrame, and
many more objects now that they are no longer using intrusive ref counted
pointer objects (you can't do std::tr1::weak_ptr functionality with intrusive
pointers).

Fixed an issues with the SBType and SBTypeMember classes:
- Fixed SBType to be able to dump itself from python
- Fixed SBType::GetNumberOfFields() to return the correct value for objective C interfaces
- Fixed SBTypeMember to be able to dump itself from python
- Fixed the SBTypeMember ability to get a field offset in bytes (the value
being returned was wrong)
- Added the SBTypeMember ability to get a field offset in bits


Cleaned up a lot of the Stream usage in the SB API files.

const data, etc, and also for SBAddress objects to classify their type of
section they are in and also getting the module for a section offset address.

lldb::SymbolType SBSymbol::GetType();

lldb::SectionType SBAddress::GetSectionType ();
lldb::SBModule SBAddress::GetModule ();

plugin by name on the command line for when there is more than one disassembler
plugin.

Taught the Opcode class to dump itself so that "disassembler -b" will dump
the bytes correctly for each opcode type. Modified all places that were passing
the opcode bytes buffer in so that the bytes could be displayed to just pass
in a bool that indicates if we should dump the opcode bytes since the opcode
now lives inside llvm_private::Instruction.

e005f2ce03c489ebde9110678a29cbfe8488d5b4 06-Nov-2010 Greg Clayton <gclayton@apple.com> Modified all logging calls to hand out shared pointers to make sure we
don't crash if we disable logging when some code already has a copy of the
logger. Prior to this fix, logs were handed out as pointers and if they were
held onto while a log got disabled, then it could cause a crash. Now all logs
are handed out as shared pointers so this problem shouldn't happen anymore.
We are also using our new shared pointers that put the shared pointer count
and the object into the same allocation for a tad better performance.

61ba7ec20f616f907473dd501341cef5b47fa3f8 27-Oct-2010 Caroline Tice <ctice@apple.com> Clean up the API logging code:
- Try to reduce logging to one line per function call instead of tw
- Put all arguments & their values into log for calls
- Add 'this' parameter information to function call logging, making it show the appropriate
internal pointer (this.obj, this.sp, this.ap...)
- Clean up some return values
- Remove logging of constructors that construct empty objects
- Change '==>' to '=>' for showing result values...
- Fix various minor bugs
- Add some protected 'get' functions to help getting the internal pointers for the 'this' arguments...

7826c8894803dc729f29789ebc038956a94d3e7a 26-Oct-2010 Caroline Tice <ctice@apple.com> First pass at adding logging capabilities for the API functions. At the moment
it logs the function calls, their arguments and the return values. This is not
complete or polished, but I am committing it now, at the request of someone who
really wants to use it, even though it's not really done. It currently does not
attempt to log all the functions, just the most important ones. I will be
making further adjustments to the API logging code over the next few days/weeks.
(Suggestions for improvements are welcome).


Update the Python build scripts to re-build the swig C++ file whenever
the python-extensions.swig file is modified.

Correct the help for 'log enable' command (give it the correct number & type of
arguments).

into python-extensions.swig, which gets included into lldb.swig, and
adds them back into the classes when swig generates it's C++ file. This
keeps the Python stuff out of the general API classes.

Also fixed a small bug in the copy constructor for SBSymbolContext.

63094e0bb161580564954dee512955c1c79d3476 23-Jun-2010 Greg Clayton <gclayton@apple.com> Very large changes that were needed in order to allow multiple connections
to the debugger from GUI windows. Previously there was one global debugger
instance that could be accessed that had its own command interpreter and
current state (current target/process/thread/frame). When a GUI debugger
was attached, if it opened more than one window that each had a console
window, there were issues where the last one to setup the global debugger
object won and got control of the debugger.

To avoid this we now create instances of the lldb_private::Debugger that each
has its own state:
- target list for targets the debugger instance owns
- current process/thread/frame
- its own command interpreter
- its own input, output and error file handles to avoid conflicts
- its own input reader stack

So now clients should call:

SBDebugger::Initialize(); // (static function)

SBDebugger debugger (SBDebugger::Create());
// Use which ever file handles you wish
debugger.SetErrorFileHandle (stderr, false);
debugger.SetOutputFileHandle (stdout, false);
debugger.SetInputFileHandle (stdin, true);

// main loop

SBDebugger::Terminate(); // (static function)

SBDebugger::Initialize() and SBDebugger::Terminate() are ref counted to
ensure nothing gets destroyed too early when multiple clients might be
attached.

Cleaned up the command interpreter and the CommandObject and all subclasses
to take more appropriate arguments.
