| | | | | | | | | | | Hello everyone, please find the attached patch for TOT and lldb-platform-work branch, which provides the following changes: - fixed a crash in the ProcessPOSIX constructor when an executable module object is not yet created. - added support for the multi instanciated FreeBSD platform objects (the local host and remote as example). - enabled the remote gdb plugin on FreeBSD. llvm-svn: 154724
* <rdar://problem/11113279>Greg Clayton2012-03-261-6/+0
| | | | | | | | | | Fixed type lookups to "do the right thing". Prior to this fix, looking up a type using "foo::bar" would result in a type list that contains all types that had "bar" as a basename unless the symbol file was able to match fully qualified names (which our DWARF parser does not). This fix will allow type matches to be made based on the basename and then have the types that don't match filtered out. Types by name can be fully qualified, or partially qualified with the new "bool exact_match" parameter to the Module::FindTypes() method. This fixes some issue that we discovered with dynamic type resolution as well as improves the overall type lookups in LLDB. llvm-svn: 153482
* Platforms can now auto-select themselves if you specify a full target triple ↵Greg Clayton2012-03-2012-17/+93

| | | | | | | | | | | | and also so we don't break them with our code changes. The _only_ plug-ins that should be #ifdef'ed out and not compiled in LLDB are those that only work when running natively on the host system. This fixed bot the PlatformLinux and PlatformFreeBSD build breakages that were due to ModuleSpec changes. llvm-svn: 151539
* Patch from Pawel Worach to make FreeBSD work again after ModuleSpec changes.Greg Clayton2012-02-272-36/+22
| | | | llvm-svn: 151532
* Made a ModuleSpec class in Module.h which can specify a module using one orGreg Clayton2012-02-266-96/+37
| | | | | | | | | | | | | | | | | | more of the local path, platform path, associated symbol file, UUID, arch, object name and object offset. This allows many of the calls that were GetSharedModule to reduce the number of arguments that were used in a call to these functions. It also allows a module to be created with a ModuleSpec which allows many things to be specified prior to any accessors being called on the Module class itself. I was running into problems when adding support for "target symbol add" where you can specify a stand alone debug info file after debugging has started where I needed to specify the associated symbol file path and if I waited until after construction, the wrong symbol file had already been located. By using the ModuleSpec it allows us to construct a module with as little or as much information as needed and not have to change the parameter list. llvm-svn: 151476
* <rdar://problem/9886712>Greg Clayton2012-02-257-90/+632
| | | | | | | | Added a dedicated platform for the iOS simulator. This helps us to find the correct files for a simulator binary before running and helps us select the right arch (i386 only) for files when we load them. llvm-svn: 151436

* Full core file support has been added for mach-o core files.Greg Clayton2012-02-138-67/+128
| | | | | | | | | | | | | | | | Tracking modules down when you have a UUID and a path has been improved. DynamicLoaderDarwinKernel no longer parses mach-o load commands and it now uses the memory based modules now that we can load modules from memory. Added a target setting named "target.exec-search-paths" which can be used to supply a list of directories to use when trying to look for executables. This allows one or more directories to be used when searching for modules that may not exist in the SDK/PDK. The target automatically adds the directory for the main executable to this list so this should help us in tracking down shared libraries and other binaries. llvm-svn: 150426
* First pass at mach-o core file support is in. It currently works for x86_64 Greg Clayton2012-02-092-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | user space programs. The core file support is implemented by making a process plug-in that will dress up the threads and stack frames by using the core file memory. Added many default implementations for the lldb_private::Process functions so that plug-ins like the ProcessMachCore don't need to override many many functions only to have to return an error. Added new virtual functions to the ObjectFile class for extracting the frozen thread states that might be stored in object files. The default implementations return no thread information, but any platforms that support core files that contain frozen thread states (like mach-o) can make a module using the core file and then extract the information. The object files can enumerate the threads and also provide the register state for each thread. Since each object file knows how the thread registers are stored, they are responsible for creating a suitable register context that can be used by the core file threads. Changed the process CreateInstace callbacks to return a shared pointer and to also take an "const FileSpec *core_file" parameter to allow for core file support. This will also allow for lldb_private::Process subclasses to be made that could load crash logs. This should be possible on darwin where the crash logs contain all of the stack frames for all of the threads, yet the crash logs only contain the registers for the crashed thrad. It should also allow some variables to be viewed for the thread that crashed. llvm-svn: 150154

| | | | | | | | | | | | | | | | | | | | | info for us to attach by pid, or by name and will also allow us to eventually do a lot more powerful attaches. If you look at the options for the "platform process list" command, there are many options which we should be able to specify. This will allow us to do things like "attach to a process named 'tcsh' that has a parent process ID of 123", or "attach to a process named 'x' which has an effective user ID of 345". I finished up the --shell implementation so that it can be used without the --tty option in "process launch". The "--shell" option now can take an optional argument which is the path to the shell to use (or a partial name like "sh" which we will find using the current PATH environment variable). Modified the Process::Attach to use the new ProcessAttachInfo as the sole argument and centralized a lot of code that was in the "process attach" Execute function so that everyone can take advantage of the powerful new attach functionality. llvm-svn: 144615

So you can now get shell expansion and file redirection: (lldb) process launch --tty --shell -- *.jpg < in.txt > out.txt Again, the "--tty" is mandatory for now until we hook this up to other functions. The shell is also currently hard coded to "/bin/bash" and not the "SHELL" variable. "/bin/tcsh" was causing problems which I need to dig into. llvm-svn: 144443

* Added to the public API to allow symbolication:Greg Clayton2011-09-242-4/+4
| | | | | | | | | | | | | | | | | - New SBSection objects that are object file sections which can be accessed through the SBModule classes. You can get the number of sections, get a section at index, and find a section by name. - SBSections can contain subsections (first find "__TEXT" on darwin, then us the resulting SBSection to find "__text" sub section). - Set load addresses for a SBSection in the SBTarget interface - Set the load addresses of all SBSection in a SBModule in the SBTarget interface - Add a new module the an existing target in the SBTarget interface - Get a SBSection from a SBAddress object This should get us a lot closer to being able to symbolicate using LLDB through the public API. llvm-svn: 140437

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

This can be specified using the platform select function: platform select --sysroot /Volumes/remote-root remote-macosx Each platform subclass is free to interpret the sysroot as needed. Expose the new SDK root directory through the SBDebugger class. Fixed an issue with the GDB remote protocol where unimplemented packets were not being handled correctly. llvm-svn: 133231

* Centralized a lot of the status information for processes,Greg Clayton2011-04-182-9/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | threads, and stack frame down in the lldb_private::Process, lldb_private::Thread, lldb_private::StackFrameList and the lldb_private::StackFrame classes. We had some command line commands that had duplicate versions of the process status output ("thread list" and "process status" for example). Removed the "file" command and placed it where it should have been: "target create". Made an alias for "file" to "target create" so we stay compatible with GDB commands. We can now have multple usable targets in lldb at the same time. This is nice for comparing two runs of a program or debugging more than one binary at the same time. The new command is "target select <target-idx>" and also to see a list of the current targets you can use the new "target list" command. The flow in a debug session can be: (lldb) target create /path/to/exe/a.out (lldb) breakpoint set --name main (lldb) run ... hit breakpoint (lldb) target create /bin/ls (lldb) run /tmp Process 36001 exited with status = 0 (0x00000000) (lldb) target list Current targets: target #0: /tmp/args/a.out ( arch=x86_64-apple-darwin, platform=localhost, pid=35999, state=stopped ) * target #1: /bin/ls ( arch=x86_64-apple-darwin, platform=localhost, pid=36001, state=exited ) (lldb) target select 0 Current targets: * target #0: /tmp/args/a.out ( arch=x86_64-apple-darwin, platform=localhost, pid=35999, state=stopped ) target #1: /bin/ls ( arch=x86_64-apple-darwin, platform=localhost, pid=36001, state=exited ) (lldb) bt * thread #1: tid = 0x2d03, 0x0000000100000b9a a.out`main + 42 at main.c:16, stop reason = breakpoint 1.1 frame #0: 0x0000000100000b9a a.out`main + 42 at main.c:16 frame #1: 0x0000000100000b64 a.out`start + 52 Above we created a target for "a.out" and ran and hit a breakpoint at "main". Then we created a new target for /bin/ls and ran it. Then we listed the targest and selected our original "a.out" program, so we showed two concurent debug sessions going on at the same time. llvm-svn: 129695
* Added auto completion for architecture names and for platforms.Greg Clayton2011-04-132-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Modified the OptionGroupOptions to be able to specify only some of the options that should be appended by using the usage_mask in the group defintions and also provided a way to remap them to a new usage mask after the copy. This allows options to be re-used and also targetted for specific option groups. Modfied the CommandArgumentType to have a new eArgTypePlatform enumeration. Taught the option parser to be able to automatically use the appropriate auto completion for a given options if nothing is explicitly specified in the option definition. So you don't have to specify it in the option definition tables. Renamed the default host platform name to "host", and the default platform hostname to be "localhost". Modified the "file" and "platform select" commands to make sure all options and args are good prior to creating a new platform. Also defer the computation of the architecture in the file command until all options are parsed and the platform has either not been specified or reset to a new value to avoid computing the arch more than once. Switch the PluginManager code over to using llvm::StringRef for string comparisons and got rid of all the AccessorXXX functions in lieu of the newer mutex + collection singleton accessors. llvm-svn: 129483
* Moved the execution context that was in the Debugger intoGreg Clayton2011-04-126-26/+267
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* Modified the ArchSpec to take an optional "Platform *" when setting the triple.Greg Clayton2011-04-072-51/+56
| | | | | | | | | | | | | | | | | | | | | | | | | | This allows you to have a platform selected, then specify a triple using "i386" and have the remaining triple items (vendor, os, and environment) set automatically. Many interpreter commands take the "--arch" option to specify an architecture triple, so now the command options needed to be able to get to the current platform, so the Options class now take a reference to the interpreter on construction. Modified the build LLVM building in the Xcode project to use the new Xcode project level user definitions: LLVM_BUILD_DIR - a path to the llvm build directory LLVM_SOURCE_DIR - a path to the llvm sources for the llvm that will be used to build lldb LLVM_CONFIGURATION - the configuration that lldb is built for (Release, Release+Asserts, Debug, Debug+Asserts). I also changed the LLVM build to not check if "lldb/llvm" is a symlink and then assume it is a real llvm build directory versus the unzipped llvm.zip package, so now you can actually have a "lldb/llvm" directory in your lldb sources. llvm-svn: 129112

| | | | | | | | | | | | | 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 Clayton2011-03-308-442/+599

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
