* While tracking down memory consumption issue a few things were needed: the Greg Clayton2011-08-101-27/+160
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ability to dump more information about modules in "target modules list". We can now dump the shared pointer reference count for modules, the pointer to the module itself (in case performance tools can help track down who has references to said pointer), and the modification time. Added "target delete [target-idx ...]" to be able to delete targets when they are no longer needed. This will help track down memory usage issues and help to resolve when module ref counts keep getting incremented. If the command gets no arguments, the currently selected target will be deleted. If any arguments are given, they must all be valid target indexes (use the "target list" command to get the current target indexes). Took care of a bunch of "no newline at end of file" warnings. TimeValue objects can now dump their time to a lldb_private::Stream object. Modified the "target modules list --global" command to not error out if there are no targets since it doesn't require a target. Fixed an issue in the MacOSX DYLD dynamic loader plug-in where if a shared library was updated on disk, we would keep using the older one, even if it was updated. Don't allow the ModuleList::GetSharedModule(...) to return an empty module. Previously we could specify a valid path on disc to a module, and specify an architecture that wasn't contained in that module and get a shared pointer to a module that wouldn't be able to return an object file or a symbol file. We now make sure an object file can be extracted prior to adding the shared pointer to the module to get added to the shared list. llvm-svn: 137196

* Public API changes:Enrico Granata2011-07-291-4/+4
| | | | | | | | | | | | | | | | | | | | | - Completely new implementation of SBType - Various enhancements in several other classes Python synthetic children providers for std::vector<T>, std::list<T> and std::map<K,V>: - these return the actual elements into the container as the children of the container - basic template name parsing that works (hopefully) on both Clang and GCC - find them in examples/synthetic and in the test suite in functionalities/data-formatter/data-formatter-python-synth New summary string token ${svar : - the syntax is just the same as in ${var but this new token lets you read the values coming from the synthetic children provider instead of the actual children - Python providers above provide a synthetic child len that returns the number of elements into the container Full bug fix for the issue in which getting byte size for a non-complete type would crash LLDB Several other fixes, including: - inverted the order of arguments in the ClangASTType constructor - EvaluationPoint now only returns SharedPointer's to Target and Process - the help text for several type subcommands now correctly indicates argument-less options as such llvm-svn: 136504

| | | | | | | | | | | | | | | indicate that you want the summary to be used to print the target object (e.g. ${var%S}). this might already be the default if your variable is of an aggregate type new feature: synthetic filters. you can restrict the number of children for your variables to only a meaningful subset - the restricted list of children obeys the typical rules (e.g. summaries prevail over children) - one-line summaries show only the filtered (synthetic) children, if you type an expanded summary string, or you use Python scripts, all the real children are accessible - to provide a synthetic children list use the "type synth add" command, as in: type synth add foo_type --child varA --child varB[0] --child varC->packet->flags[1-4] (you can use ., ->, single-item array operator [N] and bitfield operator [N-M]; array slice access is not supported, giving simplified names to expression paths is not supported) - a new -S option to frame variable and target variable lets you override synthetic children and instead show real ones llvm-svn: 135731
* Some descriptive text for the Python script feature:Enrico Granata2011-07-161-1/+2
| | | | | | | | | | | | | | | - help type summary add now gives some hints on how to use it frame variable and target variable now have a --no-summary-depth (-Y) option: - simply using -Y without an argument will skip one level of summaries, i.e. your aggregate types will expand their children and display no summary, even if they have one. children will behave normally - using -Y<int>, as in -Y4, -Y7, ..., will skip as many levels of summaries as given by the <int> parameter (obviously, -Y and -Y1 are the same thing). children beneath the given depth level will behave normally -Y0 is the same as omitting the --no-summary-depth parameter entirely This option replaces the defined-but-unimplemented --no-summary llvm-svn: 135336

| | | | | | | | | | | | | | | | | | | use lldb_private::Target::ReadMemory(...) to allow constant strings to be displayed in global variables prior on in between process execution. Centralized the variable declaration dumping into: bool Variable::DumpDeclaration (Stream *s, bool show_fullpaths, bool show_module); Fixed an issue if you used "target variable --regex <regex>" where the variable name would not be displayed, but the regular expression would. Fixed an issue when viewing global variables through "target variable" might not display correctly when doing DWARF in object files. llvm-svn: 134878
* Fixed the global and static variables to always be in scope.Greg Clayton2011-07-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | Made it so that you can create synthetic children of array value objects. This is for creating array members when the array index is out of range. This comes in handy when you have a structure definition like: struct Collection { uint32_t count; Item array[0]; }; "array" has 1 item, but many times in practice there are more items in "item_array". This allows you to do: (lldb) target variable g_collection.array[3] To implement this, the get child at index has been modified to have a "ignore_array_bounds" boolean that can be set to true. llvm-svn: 134846

| | | | | | | | | | | | | group class: OptionGroupVariable. It gets initialized with a boolean that indicates if the frame specific options are included so that this can be used in both the "frame variable" and "target variable" commands. Removed the global functionality from the "frame variable" command. Users should switch to using the "target variable" command. llvm-svn: 134594
* Added "target variable" command that allows introspection of globalGreg Clayton2011-07-071-13/+142
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | variables prior to running your binary. Zero filled sections now get section data correctly filled with zeroes when Target::ReadMemory reads from the object file section data. Added new option groups and option values for file lists. I still need to hook up all of the options to "target variable" to allow more complete introspection by file and shlib. Added the ability for ValueObjectVariable objects to be created with only the target as the execution context. This allows them to be read from the object files through Target::ReadMemory(...). Added a "virtual Module * GetModule()" function to the ValueObject class. By default it will look to the parent variable object and return its module. The module is needed when we have global variables that have file addresses (virtual addresses that are specific to module object files) and in turn allows global variables to be displayed prior to running. Removed all of the unused proxy object support that bit rotted in lldb_private::Value. Replaced a lot of places that used "FileSpec::Compare (lhs, rhs) == 0" code with the more efficient "FileSpec::Equal (lhs, rhs)". Improved logging in GDB remote plug-in. llvm-svn: 134579

| | | | | | | | | | | | | | | | | | | | | Removed the "image" command and moved it to "target modules". Added an alias for "image" to "target modules". Added some new target commands to be able to add and load modules to a target: (lldb) target modules add <path> (lldb) target modules load [--file <path>] [--slide <offset>] [<sect-name> <sect-load-addr> ...] So you can load individual sections without running a target: (lldb) target modules load --file /usr/lib/libSystem.B.dylib __TEXT 0x7fccc80000 __DATA 0x1234000000 Or you can rigidly slide an entire shared library: (lldb) target modules load --file /usr/lib/libSystem.B.dylib --slid 0x7fccc80000 This should improve bare board debugging when symbol files need to be slid around manually. llvm-svn: 130796

* This patch captures and serializes all output being written by theCaroline Tice2011-05-021-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | command line driver, including the lldb prompt being output by editline, the asynchronous process output & error messages, and asynchronous messages written by target stop-hooks. As part of this it introduces a new Stream class, StreamAsynchronousIO. A StreamAsynchronousIO object is created with a broadcaster, who will eventually broadcast the stream's data for a listener to handle, and an event type indicating what type of event the broadcaster will broadcast. When the Write method is called on a StreamAsynchronousIO object, the data is appended to an internal string. When the Flush method is called on a StreamAsynchronousIO object, it broadcasts it's data string and clears the string. Anything in lldb-core that needs to generate asynchronous output for the end-user should use the StreamAsynchronousIO objects. I have also added a new notification type for InputReaders, to let them know that a asynchronous output has been written. This is to allow the input readers to, for example, refresh their prompts and lines, if desired. I added the case statements to all the input readers to catch this notification, but I haven't added any code for handling them yet (except to the IOChannel input reader). llvm-svn: 130721
* Added a new option to the "source list" command that allows us to see whereGreg Clayton2011-04-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | line tables specify breakpoints can be set in the source. When dumping the source, the number of breakpoints that can be set on a source line are shown as a prefix: (lldb) source list -f test.c -l1 -c222 -b 1 #include <stdio.h> 2 #include <sys/fcntl.h> 3 #include <unistd.h> 4 int 5 sleep_loop (const int num_secs) [2] 6 { 7 int i; [1] 8 for (i=0; i<num_secs; ++i) 9 { [1] 10 printf("%d of %i - sleep(1);\n", i, num_secs); [1] 11 sleep(1); 12 } 13 return 0; [1] 14 } 15 16 int 17 main (int argc, char const* argv[]) [1] 18 { [1] 19 printf("Process: %i\n\n", getpid()); [1] 20 puts("Press any key to continue..."); getchar(); [1] 21 sleep_loop (20); 22 return 12; [1] 23 } Above we can see there are two breakpoints for line 6 and one breakpoint for lines 8, 10, 11, 14, 18, 19, 20, 21 and 23. All other lines have no line table entries for them. This helps visualize the data provided in the debug information without having to manually dump all line tables. It also includes all inline breakpoint that may result for a given file which can also be very handy to see. llvm-svn: 129747

* Centralized a lot of the status information for processes,Greg Clayton2011-04-181-23/+385
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 two new classes for command options:Greg Clayton2011-04-131-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | lldb_private::OptionGroup lldb_private::OptionGroupOptions OptionGroup lets you define a class that encapsulates settings that you want to reuse in multiple commands. It contains only the option definitions and the ability to set the option values, but it doesn't directly interface with the lldb_private::Options class that is the front end to all of the CommandObject option parsing. For that the OptionGroupOptions class can be used. It aggregates one or more OptionGroup objects and directs the option setting to the appropriate OptionGroup class. For an example of this, take a look at the CommandObjectFile and how it uses its "m_option_group" object shown below to be able to set values in both the FileOptionGroup and PlatformOptionGroup classes. The members used in CommandObjectFile are: OptionGroupOptions m_option_group; FileOptionGroup m_file_options; PlatformOptionGroup m_platform_options; Then in the constructor for CommandObjectFile you can combine the option settings. The code below shows a simplified version of the constructor: CommandObjectFile::CommandObjectFile(CommandInterpreter &interpreter) : CommandObject (...), m_option_group (interpreter), m_file_options (), m_platform_options(true) { m_option_group.Append (&m_file_options); m_option_group.Append (&m_platform_options); m_option_group.Finalize(); } We append the m_file_options and then the m_platform_options and then tell the option group the finalize the results. This allows the m_option_group to become the organizer of our prefs and after option parsing we end up with valid preference settings in both the m_file_options and m_platform_options objects. This also allows any other commands to use the FileOptionGroup and PlatformOptionGroup classes to implement options for their commands. Renamed: virtual void Options::ResetOptionValues(); to: virtual void Options::OptionParsingStarting(); And implemented a new callback named: virtual Error Options::OptionParsingFinished(); This allows Options subclasses to verify that the options all go together after all of the options have been specified and gives the chance for the command object to return an error. It also gives a chance to take all of the option values and produce or initialize objects after all options have completed parsing. Modfied: virtual Error SetOptionValue (int option_idx, const char *option_arg) = 0; to be: virtual Error SetOptionValue (uint32_t option_idx, const char *option_arg) = 0; (option_idx is now unsigned). llvm-svn: 129415
* Modified the ArchSpec to take an optional "Platform *" when setting the triple.Greg Clayton2011-04-071-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | 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
* Fixed the LLDB build so that we can have private types, private enums andGreg Clayton2011-03-241-3/+3

* Add a first pass at a "stop hook" mechanism. This allows you to add ↵Jim Ingham2011-03-111-2/+618
| | | | | | | | commands that get run every time the debugger stops, whether due to a breakpoint, the end of a step, interrupt, etc. You can also specify in which context you want the stop hook to run, for instance only on a particular thread, or only in a particular shared library, function, file, line range within a file. Still need to add "in methods of a class" to the specifiers, and the ability to write the stop hooks in the Scripting language as well as in the Command Language. llvm-svn: 127457

* Fixed the way set/show variables were being accessed to being natively Greg Clayton2010-09-181-36/+39
| | | | | | | | | | | | | | | | | | accessed by the objects that own the settings. The previous approach wasn't very usable and made for a lot of unnecessary code just to access variables that were already owned by the objects. While I fixed those things, I saw that CommandObject objects should really have a reference to their command interpreter so they can access the terminal with if they want to output usaage. Fixed up all CommandObjects to take an interpreter and cleaned up the API to not need the interpreter to be passed in. Fixed the disassemble command to output the usage if no options are passed down and arguments are passed (all disassebmle variants take options, there are no "args only"). llvm-svn: 114252

I didn't change "CurrentProcess" since this is always controlled by the target, and a given target can only have one process, so it really can't be selected. llvm-svn: 112221
* Very large changes that were needed in order to allow multiple connectionsGreg Clayton2010-06-231-34/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. llvm-svn: 106615
