* Add a SBQueue::GetKind() method to retrieve the type of libdispatch queue ↵Jason Molenda2014-03-131-0/+19

Complete the work of adding QueueItems to Queues and allow for the QueueItems to be interrogated about their extended backtraces in turn. There's still cleanup and documentation to do on this code but the code is functional and I it's a good time to get the work-in-progress checked in. <rdar://problem/15314027> llvm-svn: 200822
* Roll back the changes I made in r193907 which created a new FrameJason Molenda2013-11-041-1/+1
| | | | | | | | | | pure virtual base class and made StackFrame a subclass of that. As I started to build on top of that arrangement today, I found that it wasn't working out like I intended. Instead I'll try sticking with the single StackFrame class -- there's too much code duplication to make a more complicated class hierarchy sensible I think. llvm-svn: 193983
* Add a new base class, Frame. It is a pure virtual function whichJason Molenda2013-11-021-1/+1
| | | | | | | | | | | | | | | | | | | | | defines a protocol that all subclasses will implement. StackFrame is currently the only subclass and the methods that Frame vends are nearly identical to StackFrame's old methods. Update all callers to use Frame*/Frame& instead of pointers to StackFrames. This is almost entirely a mechanical change that touches a lot of the code base so I'm committing it alone. No new functionality is added with this patch, no new subclasses of Frame exist yet. I'll probably need to tweak some of the separation, possibly moving some of StackFrame's methods up in to Frame, but this is a good starting point. <rdar://problem/15314068> llvm-svn: 193907

* Discover support of 'p' packet.Hafiz Abid Qadeer2013-08-291-1/+2

* Changed the formerly pure virtual function:Greg Clayton2013-05-091-45/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | namespace lldb_private { class Thread { virtual lldb::StopInfoSP GetPrivateStopReason() = 0; }; } To not be virtual. The lldb_private::Thread now handles the correct caching and will call a new pure virtual function: namespace lldb_private { class Thread { virtual bool CalculateStopInfo() = 0; } } This function must be overridden by thead lldb_private::Thread subclass and the only thing it needs to do is to set the Thread::StopInfo() with the current stop reason and return true, or return false if there is no stop reason. The lldb_private::Thread class will take care of calling this function only when it is required. This allows lldb_private::Thread subclasses to be a bit simpler and not all need to duplicate the cache and invalidation settings. Also renamed: lldb::StopInfoSP lldb_private::Thread::GetPrivateStopReason(); To: lldb::StopInfoSP lldb_private::Thread::GetPrivateStopInfo(); Also cleaned up a case where the ThreadPlanStepOverBreakpoint might not re-set its breakpoint if the thread disappears (which was happening due to a bug when using the OperatingSystem plug-ins with memory threads and real threads). llvm-svn: 181501

* After recent OperatingsSystem plug-in changes, the lldb_private::Process and ↵Greg Clayton2013-05-041-19/+38
| | | | | | | | | | lldb_private::Thread subclasses were changed and the API was not respected properly. This checkin aims to fix this. The process now has two thread lists: a real thread list for threads that are created by the lldb_private::Process subclass, and the user visible threads. The user visible threads are the same as the real threas when no OS plug-in in used. But when an OS plug-in is used, the user thread can be a combination of real and "memory" threads. Real threads can be placed inside of memory threads so that a thread appears to be different, but is still controlled by the actual real thread. When the thread list needs updating, the lldb_private::Process class will call the: lldb_private::Process::UpdateThreadList() function with the old real thread list, and the function is expected to fill in the new real thread list with the current state of the process. After this function, the process will check if there is an OS plug-in being used, and if so, it will give the old user thread list, the new real thread list and the OS plug-in will create the new user thread list from both of these lists. If there is no OS plug-in, the real thread list is the user thread list. These changes keep the lldb_private::Process subclasses clean and no changes are required. llvm-svn: 181091
* <rdar://problem/13700260>Greg Clayton2013-05-011-30/+8
| | | | | | | | | | | | | | <rdar://problem/13723772> Modified the lldb_private::Thread to work much better with the OperatingSystem plug-ins. Operating system plug-ins can now return have a "core" key/value pair in each thread dictionary for the OperatingSystemPython plug-ins which allows the core threads to be contained with memory threads. It also allows these memory threads to be stepped, resumed, and controlled just as if they were the actual backing threads themselves. A few things are introduced: - lldb_private::Thread now has a GetProtocolID() method which returns the thread protocol ID for a given thread. The protocol ID (Thread::GetProtocolID()) is usually the same as the thread id (Thread::GetID()), but it can differ when a memory thread has its own id, but is backed by an actual API thread. - Cleaned up the Thread::WillResume() code to do the mandatory parts in Thread::ShouldResume(), and let the thread subclasses override the Thread::WillResume() which is now just a notification. - Cleaned up ClearStackFrames() implementations so that fewer thread subclasses needed to override them - Changed the POSIXThread class a bit since it overrode Thread::WillResume(). It is doing the wrong thing by calling "Thread::SetResumeState()" on its own, this shouldn't be done by thread subclasses, but the current code might rely on it so I left it in with a TODO comment with an explanation. llvm-svn: 180886
* <rdar://problem/13491977>Greg Clayton2013-04-121-2/+6
| | | | | | | | Made some fixes to the OperatingSystemPython class: - If any thread dictionary contains any "core=N" key/value pairs then the threads obtained from the lldb_private::Process itself will be placed inside the ThreadMemory threads and will be used to get the information for a thread. - Cleaned up all the places where a thread inside a thread was causing problems llvm-svn: 179405
* <rdar://problem/13521159>Greg Clayton2013-03-271-1/+1
| | | | | | | | 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. llvm-svn: 178191

| | | | | | | | | | | | | ProcessSP. We can't create Threads with a NULL ProcessSP, so it makes no sense to use the SP. Then make the Thread a Broadcaster, and get it to broadcast when the selected frame is changed (but only from the Command Line) and when Thread::ReturnFromFrame changes the stack. Made the Driver use this notification to print the new thread status rather than doing it in the command. Fixed a few places where people were setting their broadcaster class by hand rather than using the static broadcaster class call. <rdar://problem/12383087> llvm-svn: 165640

* Thread hardening part 3. Now lldb_private::Thread objects have std::weak_ptrGreg Clayton2012-02-211-48/+80
| | | | | | | | | | | | | | | | | objects for the backlink to the lldb_private::Process. The issues we were running into before was someone was holding onto a shared pointer to a lldb_private::Thread for too long, and the lldb_private::Process parent object would get destroyed and the lldb_private::Thread had a "Process &m_process" member which would just treat whatever memory that used to be a Process as a valid Process. This was mostly happening for lldb_private::StackFrame objects that had a member like "Thread &m_thread". So this completes the internal strong/weak changes. Documented the ExecutionContext and ExecutionContextRef classes so that our LLDB developers can understand when and where to use ExecutionContext and ExecutionContextRef objects. llvm-svn: 151009

With DWARF in .o files the type ID was the DIE offset in the DWARF for the .o file which is not unique across all .o files, so now the SymbolFileDWARFDebugMap class will make the .o file index part (the high 32 bits) of the unique type identifier so it can uniquely identify the types. llvm-svn: 142534

Removed SBFrame::WatchValue() and SBFrame::WatchLocation() API as a result of that. Modified the watchpoint related test suite to reflect the change. Plus replacing WatchpointLocation with Watchpoint throughout the code base. There are still cleanups to be dome. This patch passes the whole test suite. Check it in so that we aggressively catch regressions. llvm-svn: 141925
* Added a new plug-in type: lldb_private::OperatingSystem. The operating system Greg Clayton2011-08-221-39/+0
| | | | | | | | | | | | | | | | | | | | plug-ins are add on plug-ins for the lldb_private::Process class that can add thread contexts that are read from memory. It is common in kernels to have a lot of threads that are not currently executing on any cores (JTAG debugging also follows this sort of thing) and are context switched out whose state is stored in memory data structures. Clients can now subclass the OperatingSystem plug-ins and then make sure their Create functions correcltly only enable themselves when the right binary/target triple are being debugged. The operating system plug-ins get a chance to attach themselves to processes just after launching or attaching and are given a lldb_private::Process object pointer which can be inspected to see if the main executable, target triple, or any shared libraries match a case where the OS plug-in should be used. Currently the OS plug-ins can create new threads, define the register contexts for these threads (which can all be different if desired), and populate and manage the thread info (stop reason, registers in the register context) as the debug session goes on. llvm-svn: 138228

* Added the ability to get the return value from a ThreadPlanCallFunctionGreg Clayton2011-05-151-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | thread plan. In order to get the return value, you can call: void ThreadPlanCallFunction::RequestReturnValue (lldb::ValueSP &return_value_sp); This registers a shared pointer to a return value that will get filled in if everything goes well. After the thread plan is run the return value will be extracted for you. Added an ifdef to be able to switch between the LLVM MCJIT and the standand JIT. We currently have the standard JIT selected because we have some work to do to get the MCJIT fuctioning properly. Added the ability to call functions with 6 argument in the x86_64 ABI. Added the ability for GDBRemoteCommunicationClient to detect if the allocate and deallocate memory packets are supported and to not call allocate memory ("_M") or deallocate ("_m") if we find they aren't supported. Modified the ProcessGDBRemote::DoAllocateMemory(...) and ProcessGDBRemote::DoDeallocateMemory(...) to be able to deal with the allocate and deallocate memory packets not being supported. If they are not supported, ProcessGDBRemote will switch to calling "mmap" and "munmap" to allocate and deallocate memory instead using our trivial function call support. Modified the "void ProcessGDBRemote::DidLaunchOrAttach()" to correctly ignore the qHostInfo triple information if any was specified in the target. Currently if the target only specifies an architecture when creating the target: (lldb) target create --arch i386 a.out Then the vendor, os and environemnt will be adopted by the target. If the target was created with any triple that specifies more than the arch: (lldb) target create --arch i386-unknown-unknown a.out Then the target will maintain its triple and not adopt any new values. This can be used to help force bare board debugging where the dynamic loader for static files will get used and users can then use "target modules load ..." to set addressses for any files that are desired. Added back some convenience functions to the lldb_private::RegisterContext class for writing registers with unsigned values. Also made all RegisterContext constructors explicit to make sure we know when an integer is being converted to a RegisterValue. llvm-svn: 131370

| | | | | | | | | | | | | | | respective ABI plugins as they were plug-ins that supplied ABI specfic info. Also hookep up the UnwindAssemblyInstEmulation so that it can generate the unwind plans for ARM. Changed the way ABI plug-ins are handed out when you get an instance from the plug-in manager. They used to return pointers that would be mananged individually by each client that requested them, but now they are handed out as shared pointers since there is no state in the ABI objects, they can be shared. llvm-svn: 131193
* Got the EmulateInstruction CFI code a lot closer to producing CFI data.Greg Clayton2011-04-261-2/+2
| | | | | | | | | | | | | Switch the EmulateInstruction to use the standard RegisterInfo structure that is defined in the lldb private types intead of passing the reg kind and reg num everywhere. EmulateInstruction subclasses also need to provide RegisterInfo structs given a reg kind and reg num. This eliminates the need for the GetRegisterName() virtual function and allows more complete information to be passed around in the read/write register callbacks. Subclasses should always provide RegiterInfo structs with the generic register info filled in as well as at least one kind of register number in the RegisterInfo.kinds[] array. llvm-svn: 130256
* Changed the emulate instruction function to take emulate options whichGreg Clayton2011-04-261-7/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | are defined as enumerations. Current bits include: eEmulateInstructionOptionAutoAdvancePC eEmulateInstructionOptionIgnoreConditions Modified the EmulateInstruction class to have a few more pure virtuals that can help clients understand how many instructions the emulator can handle: virtual bool SupportsEmulatingIntructionsOfType (InstructionType inst_type) = 0; Where instruction types are defined as: //------------------------------------------------------------------ /// Instruction types //------------------------------------------------------------------ typedef enum InstructionType { eInstructionTypeAny, // Support for any instructions at all (at least one) eInstructionTypePrologueEpilogue, // All prologue and epilogue instructons that push and pop register values and modify sp/fp eInstructionTypePCModifying, // Any instruction that modifies the program counter/instruction pointer eInstructionTypeAll // All instructions of any kind } InstructionType; This allows use to tell what an emulator can do and also allows us to request these abilities when we are finding the plug-in interface. Added the ability for an EmulateInstruction class to get the register names for any registers that are part of the emulation. This helps with being able to dump and log effectively. The UnwindAssembly class now stores the architecture it was created with in case it is needed later in the unwinding process. Added a function that can tell us DWARF register names for ARM that goes along with the source/Utility/ARM_DWARF_Registers.h file: source/Utility/ARM_DWARF_Registers.c Took some of plug-ins out of the lldb_private namespace. llvm-svn: 130189
* Moved the execution context that was in the Debugger intoGreg Clayton2011-04-121-6/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | the CommandInterpreter where it was always being used. Make sure that Modules can track their object file offsets correctly to allow opening of sub object files (like the "__commpage" on darwin). Modified the Platforms to be able to launch processes. The first part of this move is the platform soon will become the entity that launches your program and when it does, it uses a new ProcessLaunchInfo class which encapsulates all process launching settings. This simplifies the internal APIs needed for launching. I want to slowly phase out process launching from the process classes, so for now we can still launch just as we used to, but eventually the platform is the object that should do the launching. Modified the Host::LaunchProcess in the MacOSX Host.mm to correctly be able to launch processes with all of the new eLaunchFlag settings. Modified any code that was manually launching processes to use the Host::LaunchProcess functions. Fixed an issue where lldb_private::Args had implicitly defined copy constructors that could do the wrong thing. This has now been fixed by adding an appropriate copy constructor and assignment operator. Make sure we don't add empty ModuleSP entries to a module list. Fixed the commpage module creation on MacOSX, but we still need to train the MacOSX dynamic loader to not get rid of it when it doesn't have an entry in the all image infos. Abstracted many more calls from in ProcessGDBRemote down into the GDBRemoteCommunicationClient subclass to make the classes cleaner and more efficient. Fixed the default iOS ARM register context to be correct and also added support for targets that don't support the qThreadStopInfo packet by selecting the current thread (only if needed) and then sending a stop reply packet. Debugserver can now start up with a --unix-socket (-u for short) and can then bind to port zero and send the port it bound to to a listening process on the other end. This allows the GDB remote platform to spawn new GDB server instances (debugserver) to allow platform debugging. llvm-svn: 129351
* Centralize the GDB remote timeout value into the GDBRemoteCommunication as aGreg Clayton2011-03-101-1/+1

* Abtracted all mach-o and ELF out of ArchSpec. This patch is a modified formGreg Clayton2011-02-231-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | of Stephen Wilson's idea (thanks for the input Stephen!). What I ended up doing was: - Got rid of ArchSpec::CPU (which was a generic CPU enumeration that mimics the contents of llvm::Triple::ArchType). We now rely upon the llvm::Triple to give us the machine type from llvm::Triple::ArchType. - There is a new ArchSpec::Core definition which further qualifies the CPU core we are dealing with into a single enumeration. If you need support for a new Core and want to debug it in LLDB, it must be added to this list. In the future we can allow for dynamic core registration, but for now it is hard coded. - The ArchSpec can now be initialized with a llvm::Triple or with a C string that represents the triple (it can just be an arch still like "i386"). - The ArchSpec can still initialize itself with a architecture type -- mach-o with cpu type and subtype, or ELF with e_machine + e_flags -- and this will then get translated into the internal llvm::Triple::ArchSpec + ArchSpec::Core. The mach-o cpu type and subtype can be accessed using the getter functions: uint32_t ArchSpec::GetMachOCPUType () const; uint32_t ArchSpec::GetMachOCPUSubType () const; But these functions are just converting out internal llvm::Triple::ArchSpec + ArchSpec::Core back into mach-o. Same goes for ELF. All code has been updated to deal with the changes. This should abstract us until later when the llvm::TargetSpec stuff gets finalized and we can then adopt it. llvm-svn: 126278
* All UnwindPlan objects are now passed around as shared pointers.Greg Clayton2011-02-151-4/+5
| | | | | | | | | | | | | ArchDefaultUnwindPlan plug-in interfaces are now cached per architecture instead of being leaked for every frame. Split the ArchDefaultUnwindPlan_x86 into ArchDefaultUnwindPlan_x86_64 and ArchDefaultUnwindPlan_i386 interfaces. There were sporadic crashes that were due to something leaking or being destroyed when doing stack crawls. This patch should clear up these issues. llvm-svn: 125541
* Added the ability to detect which vCont packets (using the "vCont?") packetGreg Clayton2011-02-121-5/+5
| | | | | | | | | are supported by the remote GDB target. We can also now deal with the lack of vCont support and send packets that the remote GDB stub can use. We also error out of the continue if LLDB tries to do something too complex when vCont isn't supported. llvm-svn: 125433

* Put more smarts into the RegisterContext base class. Now the base class hasGreg Clayton2011-01-091-14/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | a method: void RegisterContext::InvalidateIfNeeded (bool force); Each time this function is called, when "force" is false, it will only call the pure virtual "virtual void RegisterContext::InvalideAllRegisters()" if the register context's stop ID doesn't match that of the process. When the stop ID doesn't match, or "force" is true, the base class will clear its cached registers and the RegisterContext will update its stop ID to match that of the process. This helps make it easier to correctly flush the register context (possibly from multiple locations depending on when and where new registers are availabe) without inadvertently clearing the register cache when it doesn't need to be. Modified the ProcessGDBRemote plug-in to be much more efficient when it comes to: - caching the expedited registers in the stop reply packets (we were ignoring these before and it was causing us to read at least three registers every time we stopped that were already supplied in the stop reply packet). - When a thread has no stop reason, don't keep asking for the thread stopped info. Prior to this fix we would continually send a qThreadStopInfo packet over and over when any thread stop info was requested. We now note the stop ID that the stop info was requested for and avoid multiple requests. Cleaned up some of the expression code to not look for ClangExpressionVariable objects up by name since they are now shared pointers and we can just look for the exact pointer match and avoid possible errors. Fixed an bug in the ValueObject code that would cause children to not be displayed. llvm-svn: 123127
* Fixed issues with RegisterContext classes and the subclasses. There wasGreg Clayton2011-01-061-10/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | an issue with the way the UnwindLLDB was handing out RegisterContexts: it was making shared pointers to register contexts and then handing out just the pointers (which would get put into shared pointers in the thread and stack frame classes) and cause double free issues. MallocScribble helped to find these issues after I did some other cleanup. To help avoid any RegisterContext issue in the future, all code that deals with them now returns shared pointers to the register contexts so we don't end up with multiple deletions. Also now that the RegisterContext class doesn't require a stack frame, we patched a memory leak where a StackFrame object was being created and leaked. Made the RegisterContext class not have a pointer to a StackFrame object as one register context class can be used for N inlined stack frames so there is not a 1 - 1 mapping. Updates the ExecutionContextScope part of the RegisterContext class to never return a stack frame to indicate this when it is asked to recreate the execution context. Now register contexts point to the concrete frame using a concrete frame index. Concrete frames are all of the frames that are actually formed on the stack of a thread. These concrete frames can be turned into one or more user visible frames due to inlining. Each inlined stack frame has the exact same register context (shared via shared pointers) as any parent inlined stack frames all the way up to the concrete frame itself. So now the stack frames and the register contexts should behave much better. llvm-svn: 122976

* Added support for inlined stack frames being represented as real stack framesGreg Clayton2010-08-241-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | which is now on by default. Frames are gotten from the unwinder as concrete frames, then if inline frames are to be shown, extra information to track and reconstruct these frames is cached with each Thread and exanded as needed. I added an inline height as part of the lldb_private::StackID class, the class that helps us uniquely identify stack frames. This allows for two frames to shared the same call frame address, yet differ only in inline height. Fixed setting breakpoint by address to not require addresses to resolve. A quick example: % cat main.cpp % ./build/Debug/lldb test/stl/a.out Current executable set to 'test/stl/a.out' (x86_64). (lldb) breakpoint set --address 0x0000000100000d31 Breakpoint created: 1: address = 0x0000000100000d31, locations = 1 (lldb) r Launching 'a.out' (x86_64) (lldb) Process 38031 Stopped * thread #1: tid = 0x2e03, pc = 0x0000000100000d31, where = a.out`main [inlined] std::string::_M_data() const at /usr/include/c++/4.2.1/bits/basic_string.h:280, stop reason = breakpoint 1.1, queue = com.apple.main-thread 277 278 _CharT* 279 _M_data() const 280 -> { return _M_dataplus._M_p; } 281 282 _CharT* 283 _M_data(_CharT* __p) (lldb) bt thread #1: tid = 0x2e03, stop reason = breakpoint 1.1, queue = com.apple.main-thread frame #0: pc = 0x0000000100000d31, where = a.out`main [inlined] std::string::_M_data() const at /usr/include/c++/4.2.1/bits/basic_string.h:280 frame #1: pc = 0x0000000100000d31, where = a.out`main [inlined] std::string::_M_rep() const at /usr/include/c++/4.2.1/bits/basic_string.h:288 frame #2: pc = 0x0000000100000d31, where = a.out`main [inlined] std::string::size() const at /usr/include/c++/4.2.1/bits/basic_string.h:606 frame #3: pc = 0x0000000100000d31, where = a.out`main [inlined] operator<< <char, std::char_traits<char>, std::allocator<char> > at /usr/include/c++/4.2.1/bits/basic_string.h:2414 frame #4: pc = 0x0000000100000d31, where = a.out`main + 33 at /Volumes/work/gclayton/Documents/src/lldb/test/stl/main.cpp:14 frame #5: pc = 0x0000000100000d08, where = a.out`start + 52 Each inline frame contains only the variables that they contain and each inlined stack frame is treated as a single entity. llvm-svn: 111877

* Abtracted the old "lldb_private::Thread::StopInfo" into an abtract class.Greg Clayton2010-08-041-16/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This will allow debugger plug-ins to make any instance of "lldb_private::StopInfo" that can completely describe any stop reason. It also provides a framework for doing intelligent things with the stop info at important times in the lifetime of the inferior. Examples include the signal stop info in StopInfoUnixSignal. It will check with the process to see that the current action is for the signal. These actions include wether to stop for the signal, wether the notify that the signal was hit, and wether to pass the signal along to the inferior process. The StopInfoUnixSignal class overrides the "ShouldStop()" method of StopInfo and this allows the stop info to determine if it should stop at the signal or continue the process. StopInfo subclasses must override the following functions: virtual lldb::StopReason GetStopReason () const = 0; virtual const char * GetDescription () = 0; StopInfo subclasses can override the following functions: // If the subclass returns "false", the inferior will resume. The default // version of this function returns "true" which means the default stop // info will stop the process. The breakpoint subclass will check if // the breakpoint wants us to stop by calling any installed callback on // the breakpoint, and also checking if the breakpoint is for the current // thread. Signals will check if they should stop based off of the // UnixSignal settings in the process. virtual bool ShouldStop (Event *event_ptr); // Sublasses can state if they want to notify the debugger when "ShouldStop" // returns false. This would be handy for breakpoints where you want to // log information and continue and is also used by the signal stop info // to notify that a signal was received (after it checks with the process // signal settings). virtual bool ShouldNotify (Event *event_ptr) { return false; } // Allow subclasses to do something intelligent right before we resume. // The signal class will figure out if the signal should be propagated // to the inferior process and pass that along to the debugger plug-ins. virtual void WillResume (lldb::StateType resume_state) { // By default, don't do anything } The support the Mach exceptions was moved into the lldb/source/Plugins/Process/Utility folder and now doesn't polute the lldb_private::Thread class with platform specific code. llvm-svn: 110184
