* Expose SBPlatform through the public API.Greg Clayton2013-11-203-27/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Example code: remote_platform = lldb.SBPlatform("remote-macosx"); remote_platform.SetWorkingDirectory("/private/tmp") debugger.SetSelectedPlatform(remote_platform) connect_options = lldb.SBPlatformConnectOptions("connect://localhost:1111"); err = remote_platform.ConnectRemote(connect_options) if err.Success(): print >> result, 'Connected to remote platform:' print >> result, 'hostname: %s' % (remote_platform.GetHostname()) src = lldb.SBFileSpec("/Applications/Xcode.app/Contents/SharedFrameworks/LLDB.framework", False) dst = lldb.SBFileSpec() # copy src to platform working directory since "dst" is empty err = remote_platform.Install(src, dst); if err.Success(): print >> result, '%s installed successfully' % (src) else: print >> result, 'error: failed to install "%s": %s' % (src, err) Implemented many calls needed in lldb-platform to be able to install a directory that contains symlinks, file and directories. The remote lldb-platform can now launch GDB servers on the remote system so that remote debugging can be spawned through the remote platform when connected to a remote platform. The API in SBPlatform is subject to change and will be getting many new functions. llvm-svn: 195273

| | | | | | | | | | | | | | | | | | | Removing Host/Atomic.h This header file was not being copied as part of our public API headers and this in turn was causing any plugin to link against LLDB.framework, since SharingPtr.h depends on it Out of several possible options to fix this issue, the cleanest one is to revert LLDB to use std::atomic<>, as we are a C++11 project and should take advantage of it The original rationale for going from std::atomic to Host/Atomic.h was that MSVC++ fails to link in CLR mode when std::atomic is used This is a very Visual Studio/.net specific issue, which hopefully will be fixed Until them, to allow Windows development to proceed, we are going with a targeted solution where we #ifdef include the Windows specific calls, and let everyone else use the proper atomic support, as should be If there is an unavoidable need for a LLDB-specific atomic header, the right way to go at it would be to make an API/lldb-atomic.h header and #ifdef the Windows dependency there The FormatManager should not need to conditionalize use of std::atomic<>, as other parts of the LLDB internals are successfully using atomic (Address and IRExecutionUnit), so this Win-specific hack is limited to SharingPtr llvm-svn: 192993

* merge lldb-platform-work branch (and assorted fixes) into trunkDaniel Malea2013-08-264-6/+149
| | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This merge brings in the improved 'platform' command that knows how to interface with remote machines; that is, query OS/kernel information, push and pull files, run shell commands, etc... and implementation for the new communication packets that back that interface, at least on Darwin based operating systems via the POSIXPlatform class. Linux support is coming soon. 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' Reviewers: Matt Kopec, Greg Clayton Review: http://llvm-reviews.chandlerc.com/D1493 llvm-svn: 189295

| | | | | | | | | | | | Major fixed to allow reading files that are over 4GB. The main problems were that the DataExtractor was using 32 bit offsets as a data cursor, and since we mmap all of our object files we could run into cases where if we had a very large core file that was over 4GB, we were running into the 4GB boundary. So I defined a new "lldb::offset_t" which should be used for all file offsets. After making this change, I enabled warnings for data loss and for enexpected implicit conversions temporarily and found a ton of things that I fixed. Any functions that take an index internally, should use "size_t" for any indexes and also should return "size_t" for any sizes of collections. llvm-svn: 173463

| | | | | | | | | | | | | | | | | | | Initial step -- infrastructure change -- to fix the bug. Change the RegisterInfo data structure to contain two additional fields (uint32_t *value_rges and uint32_t *invalidate_regs) to facilitate architectures which have register mapping. Update all existing RegsiterInfo arrays to have two extra NULL's (the additional fields) in each row, GDBRemoteRegisterContext.cpp is modified to add d0-d15 and q0-q15 register info entries which take advantage of the value_regs field to specify the containment relationship: d0 -> (s0, s1) ... d15 -> (s30, s31) q0 -> (d0, d1) ... q15 -> (d30, d31) llvm-svn: 151686

| | | | | | | | | We had some cases where getting the shared pointer for a module from the global module list was causing a performance issue when debugging with DWARF in .o files. Now that the module uses intrusive ref counts, we can easily convert any pointer to a shared pointer. llvm-svn: 139983

The code also looks into a bundle if the dSYM file is right next to a bundle. Modified the MacOSX kernel dynamic loader plug-in to correctly set the load address for kext sections. This is a tad tricky because of how LLDB chooses to treat mach-o segments with no name. Also modified the loader to properly handle the older version 1 kext summary info. Fixed a crasher in the Mach-o object file parser when it is trying to set the section size correctly for dSYM sections. Added packet dumpers to the CommunicationKDP class. We now also properly detect address byte sizes based on the cpu type and subtype that is provided. Added a read memory and read register support to CommunicationKDP. Added a ThreadKDP class that now uses subclasses of the RegisterContextDarwin_XXX for arm, i386 and x86_64. Fixed some register numbering issues in the RegisterContextDarwin_arm class and added ARM GDB numbers to the ARM_GCC_Registers.h file. Change the RegisterContextMach_XXX classes over to subclassing their RegisterContextDarwin_XXX counterparts so we can share the mach register contexts between the user and kernel plug-ins. llvm-svn: 135466

* Got the EmulateInstruction CFI code a lot closer to producing CFI data.Greg Clayton2011-04-263-191/+394
| | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | GDBRemoteCommunicationServer classes. This involved adding a new packet named "qSpeedTest" which can test the speed of a packet send/response pairs using a wide variety of send/recv packet sizes. Added a few new connection classes: one for shared memory, and one for using mach messages (Apple only). The mach message stuff is experimental and not working yet, but added so I don't lose the code. The shared memory stuff uses pretty standard calls to setup shared memory. llvm-svn: 128837
* Many improvements to the Platform base class and subclasses. The base PlatformGreg Clayton2011-03-304-1/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | class now implements the Host functionality for a lot of things that make sense by default so that subclasses can check: int PlatformSubclass::Foo () { if (IsHost()) return Platform::Foo (); // Let the platform base class do the host specific stuff // Platform subclass specific code... int result = ... return result; } Added new functions to the platform: virtual const char *Platform::GetUserName (uint32_t uid); virtual const char *Platform::GetGroupName (uint32_t gid); The user and group names are cached locally so that remote platforms can avoid sending packets multiple times to resolve this information. Added the parent process ID to the ProcessInfo class. Added a new ProcessInfoMatch class which helps us to match processes up and changed the Host layer over to using this new class. The new class allows us to search for processs: 1 - by name (equal to, starts with, ends with, contains, and regex) 2 - by pid 3 - And further check for parent pid == value, uid == value, gid == value, euid == value, egid == value, arch == value, parent == value. This is all hookup up to the "platform process list" command which required adding dumping routines to dump process information. If the Host class implements the process lookup routines, you can now lists processes on your local machine: machine1.foo.com % lldb (lldb) platform process list PID PARENT USER GROUP EFF USER EFF GROUP TRIPLE NAME ====== ====== ========== ========== ========== ========== ======================== ============================ 99538 1 username usergroup username usergroup x86_64-apple-darwin FileMerge 94943 1 username usergroup username usergroup x86_64-apple-darwin mdworker 94852 244 username usergroup username usergroup x86_64-apple-darwin Safari 94727 244 username usergroup username usergroup x86_64-apple-darwin Xcode 92742 92710 username usergroup username usergroup i386-apple-darwin debugserver This of course also works remotely with the lldb-platform: machine1.foo.com % lldb-platform --listen 1234 machine2.foo.com % lldb (lldb) platform create remote-macosx Platform: remote-macosx Connected: no (lldb) platform connect connect://localhost:1444 Platform: remote-macosx Triple: x86_64-apple-darwin OS Version: 10.6.7 (10J869) Kernel: Darwin Kernel Version 10.7.0: Sat Jan 29 15:17:16 PST 2011; root:xnu-1504.9.37~1/RELEASE_I386 Hostname: machine1.foo.com Connected: yes (lldb) platform process list PID PARENT USER GROUP EFF USER EFF GROUP TRIPLE NAME ====== ====== ========== ========== ========== ========== ======================== ============================ 99556 244 username usergroup username usergroup x86_64-apple-darwin trustevaluation 99548 65539 username usergroup username usergroup x86_64-apple-darwin lldb 99538 1 username usergroup username usergroup x86_64-apple-darwin FileMerge 94943 1 username usergroup username usergroup x86_64-apple-darwin mdworker 94852 244 username usergroup username usergroup x86_64-apple-darwin Safari The lldb-platform implements everything with the Host:: layer, so this should "just work" for linux. I will probably be adding more stuff to the Host layer for launching processes and attaching to processes so that this support should eventually just work as well. Modified the target to be able to be created with an architecture that differs from the main executable. This is needed for iOS debugging since we can have an "armv6" binary which can run on an "armv7" machine, so we want to be able to do: % lldb (lldb) platform create remote-ios (lldb) file --arch armv7 a.out Where "a.out" is an armv6 executable. The platform then can correctly decide to open all "armv7" images for all dependent shared libraries. Modified the disassembly to show the current PC value. Example output: (lldb) disassemble --frame a.out`main: 0x1eb7: pushl %ebp 0x1eb8: movl %esp, %ebp 0x1eba: pushl %ebx 0x1ebb: subl $20, %esp 0x1ebe: calll 0x1ec3 ; main + 12 at test.c:18 0x1ec3: popl %ebx -> 0x1ec4: calll 0x1f12 ; getpid 0x1ec9: movl %eax, 4(%esp) 0x1ecd: leal 199(%ebx), %eax 0x1ed3: movl %eax, (%esp) 0x1ed6: calll 0x1f18 ; printf 0x1edb: leal 213(%ebx), %eax 0x1ee1: movl %eax, (%esp) 0x1ee4: calll 0x1f1e ; puts 0x1ee9: calll 0x1f0c ; getchar 0x1eee: movl $20, (%esp) 0x1ef5: calll 0x1e6a ; sleep_loop at test.c:6 0x1efa: movl $12, %eax 0x1eff: addl $20, %esp 0x1f02: popl %ebx 0x1f03: leave 0x1f04: ret This can be handy when dealing with the new --line options that was recently added: (lldb) disassemble --line a.out`main + 13 at test.c:19 18 { -> 19 printf("Process: %i\n\n", getpid()); 20 puts("Press any key to continue..."); getchar(); -> 0x1ec4: calll 0x1f12 ; getpid 0x1ec9: movl %eax, 4(%esp) 0x1ecd: leal 199(%ebx), %eax 0x1ed3: movl %eax, (%esp) 0x1ed6: calll 0x1f18 ; printf Modified the ModuleList to have a lookup based solely on a UUID. Since the UUID is typically the MD5 checksum of a binary image, there is no need to give the path and architecture when searching for a pre-existing image in an image list. Now that we support remote debugging a bit better, our lldb_private::Module needs to be able to track what the original path for file was as the platform knows it, as well as where the file is locally. The module has the two following functions to retrieve both paths: const FileSpec &Module::GetFileSpec () const; const FileSpec &Module::GetPlatformFileSpec () const; llvm-svn: 128563
* Did a lot more work on abtracting and organizing the platforms. Greg Clayton2011-03-242-1/+7
| | | | | | | | | | | | | | | | | | | | On Mac OS X we now have 3 platforms: PlatformDarwin - must be subclassed to fill in the missing pure virtual funcs but this implements all the common functionality between remote-macosx and remote-ios. It also allows for another platform to be used (remote-gdb-server for now) when doing remote connections. Keeping this pluggable will allow for flexibility. PlatformMacOSX - Now implements both local and remote macosx desktop platforms. PlatformRemoteiOS - Remote only iOS that knows how to locate SDK files in the cached SDK locations on the host. A new agnostic platform has been created: PlatformRemoteGDBServer - this implements the platform using the GDB remote protocol and uses the built in lldb_private::Host static functions to implement many queries. llvm-svn: 128193

| | | | | | | | | | | | | | | | | | | | | | | | | Modifed lldb_private::Process to be able to handle connecting to a remote target that isn't running a process.

Modified ProcessGDBRemote to be able to set stdin, stdout, stderr, working dir, disable ASLR and a few other settings down by using new GDB remote packets. This allows us to keep all of our current launch flags and settings intact and still be able to communicate them over to the remote GDB server. Previously these were being sent as arguments to the debugserver binary that we were spawning. Also modified ProcessGDBRemote to handle losing connection to the remote GDB server and always exit immediately. We do this by watching the lldb_private::Communication event bit for the read thread exiting in the ProcessGDBRemote async thread. Added support for many of the new 'Q' packets for setting stdin, stdout, stderr, working dir and disable ASLR to the GDBRemoteCommunication class for easy accesss. Modified debugserver for all of the new 'Q' packets and also made it so that debugserver always exists if it loses connection with the remote debugger. llvm-svn: 126444
* All UnwindPlan objects are now passed around as shared pointers.Greg Clayton2011-02-151-6/+20
| | | | | | | | | | | | | 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

* Thread safety changes in debugserver and also in the process GDB remote plugin.Greg Clayton2011-01-181-0/+8
| | | | | | | | | | | | | | I added support for asking if the GDB remote server supports thread suffixes for packets that should be thread specific (register read/write packets) because the way the GDB remote protocol does it right now is to have a notion of a current thread for register and memory reads/writes (set via the "$Hg%x" packet) and a current thread for running ("$Hc%x"). Now we ask the remote GDB server if it supports adding the thread ID to the register packets and we enable that feature in LLDB if supported. This stops us from having to send a bunch of packets that update the current thread ID to some value which is prone to error, or extra packets. llvm-svn: 123762

This allows for thread names to contain special characters such as $ # : ; + - Debugserver now detects if the thread name contains special characters and sends the chars in hex format if needed. llvm-svn: 123053
