[lldb][NFC] Fix all formatting errors in .cpp file headers Summary: A *.cpp file header in LLDB (and in LLDB) should like this: ``` //===-- TestUtilities.cpp -------------------------------------------------===// ``` However in LLDB most of our source files have arbitrary changes to this format and these changes are spreading through LLDB as folks usually just use the existing source files as templates for their new files (most notably the unnecessary editor language indicator `-*- C++ -*-` is spreading and in every review someone is pointing out that this is wrong, resulting in people pointing out that this is done in the same way in other files). This patch removes most of these inconsistencies including the editor language indicators, all the different missing/additional '-' characters, files that center the file name, missing trailing `===//` (mostly caused by clang-format breaking the line).

Update the file headers across all of the LLVM projects in the monorepo to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351636

[trace][intel pt] Implement the Intel PT cursor D104422 added the interface for TraceCursor, which is the main way to traverse instructions in a trace. This diff implements the corresponding cursor class for Intel PT and deletes the now obsolete code. Besides that, the logic for the "thread trace dump instructions" was adapted to use this cursor (pretty much I ended up moving code from Trace.cpp to TraceCursor.cpp). The command by default traverses the instructions backwards, and if the user passes --forwards, then it's not forwards. More information about that is in the Options.td file. Regarding the Intel PT cursor. All Intel PT cursors for the same thread share the same DecodedThread instance. I'm not yet implementing lazy decoding because we don't need it. That'll be for later. For the time being, the entire thread trace is decoded when the first cursor for that thread is requested. Differential Revision: https://reviews.llvm.org/D105531

[trace][intel-pt] Scaffold the 'thread trace start | stop' commands Depends on D90490. The stop command is simple and invokes the new method Trace::StopTracingThread(thread). On the other hand, the start command works by delegating its implementation to a CommandObject provided by the Trace plugin. This is necessary because each trace plugin needs different options for this command. There's even the chance that a Trace plugin can't support live tracing, but instead supports offline decoding and analysis, which means that "thread trace dump instructions" works but "thread trace start" doest. Because of this and a few other reasons, it's better to have each plugin provide this implementation. Besides, I'm using the GetSupportedTraceType method introduced in D90490 to quickly infer what's the trace plug-in that works for the current process. As an implementation note, I moved CommandObjectIterateOverThreads to its header so that I can use it from the IntelPT plugin.

[trace][intel-pt] Implement trace start and trace stop This implements the interactive trace start and stop methods. This diff ended up being much larger than I anticipated because, by doing it, I found that I had implemented in the beginning many things in a non optimal way. In any case, the code is much better now. There's a lot of boilerplate code due to the gdb-remote protocol, but the main changes are: - New tracing packets: jLLDBTraceStop, jLLDBTraceStart, jLLDBTraceGetBinaryData. The gdb-remote packet definitions are quite comprehensive. - Implementation of the "process trace start|stop" and "thread trace start|stop" commands. - Implementaiton of an API in Trace.h to interact with live traces. - Created an IntelPTDecoder for live threads, that use the debugger's stop id as checkpoint for its internal cache. - Added a functionality to stop the process in case "process tracing" is enabled and a new thread can't traced. - Added tests I have some ideas to unify the code paths for post mortem and live threads, but I'll do that in another diff.

<rdar://problem/11757916> Make breakpoint setting by file and line much more efficient by only looking for inlined breakpoint locations if we are setting a breakpoint in anything but a source implementation file. Implementing this complex for a many reasons. Turns out that parsing compile units lazily had some issues with respect to how we need to do things with DWARF in .o files. So the fixes in the checkin for this makes these changes: - Add a new setting called "target.inline-breakpoint-strategy" which can be set to "never", "always", or "headers". "never" will never try and set any inlined breakpoints (fastest). "always" always looks for inlined breakpoint locations (slowest, but most accurate). "headers", which is the default setting, will only look for inlined breakpoint locations if the breakpoint is set in what are consudered to be header files, which is realy defined as "not in an implementation source file". - modify the breakpoint setting by file and line to check the current "target.inline-breakpoint-strategy" setting and act accordingly - Modify compile units to be able to get their language and other info lazily. This allows us to create compile units from the debug map and not have to fill all of the details in, and then lazily discover this information as we go on debuggging. This is needed to avoid parsing all .o files when setting breakpoints in implementation only files (no inlines). Otherwise we would need to parse the .o file, the object file (mach-o in our case) and the symbol file (DWARF in the object file) just to see what the compile unit was. - modify the "SymbolFileDWARFDebugMap" to subclass lldb_private::Module so that the virtual "GetObjectFile()" and "GetSymbolVendor()" functions can be intercepted when the .o file contenst are later lazilly needed. Prior to this fix, when we first instantiated the "SymbolFileDWARFDebugMap" class, we would also make modules, object files and symbol files for every .o file in the debug map because we needed to fix up the sections in the .o files with information that is in the executable debug map. Now we lazily do this in the DebugMapModule::GetObjectFile() Cleaned up header includes a bit as well. llvm-svn: 162860

Convert option tables to ArrayRefs. This change is very mechanical. All it does is change the signature of `Options::GetDefinitions()` and `OptionGroup:: GetDefinitions()` to return an `ArrayRef<OptionDefinition>` instead of a `const OptionDefinition *`. In the case of the former, it deletes the sentinel entry from every table, and in the case of the latter, it removes the `GetNumDefinitions()` method from the interface. These are no longer necessary as `ArrayRef` carries its own length. In the former case, iteration was done by using a sentinel entry, so there was no knowledge of length. Because of this the individual option tables were allowed to be defined below the corresponding class (after all, only a pointer was needed). Now, however, the length must be known at compile time to construct the `ArrayRef`, and as a result it is necessary to move every option table before its corresponding class. This results in this CL looking very big, but in terms of substance there is not much here. Differential revision: https://reviews.llvm.org/D24834 llvm-svn: 282188

CommandOptions() {
Added two new classes for command options: 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

Decoupled Options from CommandInterpreter. Options used to store a reference to the CommandInterpreter instance in the base Options class. This made it impossible to parse options independent of a CommandInterpreter. This change removes the reference from the base class. Instead, it modifies the options-parsing-related methods to take an ExecutionContext pointer, which the options may inspect if they need to do so.

*** This commit represents a complete reformatting of the LLDB source code *** to conform to clang-format’s LLVM style. This kind of mass change has *** two obvious implications: Firstly, merging this particular commit into a downstream fork may be a huge effort. Alternatively, it may be worth merging all changes up to this commit, performing the same reformatting operation locally, and then discarding the merge for this particular commit. The commands used to accomplish this reformatting were as follows (with current working directory as the root of the repository): find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} + find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ; The version of clang-format used was 3.9.0, and autopep8 was 1.2.4. Secondly, “blame” style tools will generally point to this commit instead of a meaningful prior commit. There are alternatives available that will attempt to look through this change and find the appropriate prior commit. YMMV. llvm-svn: 280751

[lldb][NFC] Remove dead code that is supposed to handle invalid command options Summary: We currently have a bunch of code that is supposed to handle invalid command options, but all this code is unreachable because invalid options are already handled in `Options::Parse`. The only way we can reach this code is when we declare but then not implement an option (which will be made impossible with D65386, which is also when we can completely remove the `default` cases). This patch replaces all this code with `llvm_unreachable` to make clear this is dead code that can't be reached.

Convert option tables to ArrayRefs. This change is very mechanical. All it does is change the signature of `Options::GetDefinitions()` and `OptionGroup:: GetDefinitions()` to return an `ArrayRef<OptionDefinition>` instead of a `const OptionDefinition *`. In the case of the former, it deletes the sentinel entry from every table, and in the case of the latter, it removes the `GetNumDefinitions()` method from the interface. These are no longer necessary as `ArrayRef` carries its own length. In the former case, iteration was done by using a sentinel entry, so there was no knowledge of length. Because of this the individual option tables were allowed to be defined below the corresponding class (after all, only a pointer was needed). Now, however, the length must be known at compile time to construct the `ArrayRef`, and as a result it is necessary to move every option table before its corresponding class. This results in this CL looking very big, but in terms of substance there is not much here. Differential revision: https://reviews.llvm.org/D24834 llvm-svn: 282188

"Show thread call stacks. Defaults to the current thread, thread "
Introduce new command: thread backtrace unique This patch introduces a new thread backtrace command "unique". The command is based off of "thread backtrace all" but will instead find all threads which share matching call stacks and de-duplicate their output, listing call stack and all the threads which share it. This is especially useful for apps which use thread/task pools sitting around waiting for work and cause excessive duplicate output. I needed this behavior recently when debugging a core with 700+ threads.

The main thread will also block on the async thread during DoResume (although with a timeout), leading to a deadlock.

Options *GetOptions() override { return &m_options; }
Add a repeat command option for "thread backtrace --count N". This way if you have a long stack, you can issue "thread backtrace --count 10" and then subsequent <Return>-s will page you through the stack. This took a little more effort than just adding the repeat command, since the GetRepeatCommand API was returning a "const char *". That meant the command had to keep the repeat string alive, which is inconvenient. The original API returned either a nullptr, or a const char *, so I changed the private API to return an llvm::Optional<std::string>. Most of the patch is propagating that change. Also, there was a little thinko in fetching the repeat command. We don't fetch repeat commands for commands that aren't being added to history, which is in general reasonable. And we don't add repeat commands to the history - also reasonable. But we do want the repeat command to be able to generate the NEXT repeat command. So I adjusted the logic in HandleCommand to work that way. Differential Revision: https://reviews.llvm.org/D119046

Also took all the cases where there were the subcommands of Multiword commands declared in the .h file for the overall command and moved them into the .cpp file. Made the CommandObject flags work for raw as well as parsed commands. Made "expr" use the flags so that it requires you to be paused to run "expr". llvm-svn: 158235

This is an idea to make "thread step-in --target" work for the common case where you have: 1 -> foo (bar(), 2 baz(), 3 lala()); 4 You are sitting on line 1, and want to step into foo, but not bar, baz & lala. Unfortunately there are line table entries for lines 1-3, and lldb doesn't know anything about the nesting of statement in these lines. So we'll have to use the user's intelligence... This patch adds: (lldb) thread step-in -t foo --end-line 4 That tells lldb to keep stepping in till line 4, but stop if you step into foo. I think I would remember to use this when faced with some of the long gnarly call sequences in lldb. But there might be ways I haven't thought of to make it more convenient. Jason suggests having "end" as a special token for --end-line which just means keep going to the end of the function, I really want to get into this thing... There should be an SB API and tests, which will come if this seems useful. llvm-svn: 260352

Centralized a lot of the status information for processes, 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

Introduce new command: thread backtrace unique This patch introduces a new thread backtrace command "unique". The command is based off of "thread backtrace all" but will instead find all threads which share matching call stacks and de-duplicate their output, listing call stack and all the threads which share it. This is especially useful for apps which use thread/task pools sitting around waiting for work and cause excessive duplicate output. I needed this behavior recently when debugging a core with 700+ threads.

Make raw & parsed commands subclasses of CommandObject rather than having the raw version implement an Execute which was never going to get run and another ExecuteRawCommandString. Took the knowledge of how to prepare raw & parsed commands out of CommandInterpreter and put it in CommandObject where it belongs. Also took all the cases where there were the subcommands of Multiword commands declared in the .h file for the overall command and moved them into the .cpp file. Made the CommandObject flags work for raw as well as parsed commands. Made "expr" use the flags so that it requires you to be paused to run "expr". llvm-svn: 158235

All it does is change the signature of `Options::GetDefinitions()` and `OptionGroup:: GetDefinitions()` to return an `ArrayRef<OptionDefinition>` instead of a `const OptionDefinition *`. In the case of the former, it deletes the sentinel entry from every table, and in the case of the latter, it removes the `GetNumDefinitions()` method from the interface. These are no longer necessary as `ArrayRef` carries its own length. In the former case, iteration was done by using a sentinel entry, so there was no knowledge of length. Because of this the individual option tables were allowed to be defined below the corresponding class (after all, only a pointer was needed). Now, however, the length must be known at compile time to construct the `ArrayRef`, and as a result it is necessary to move every option table before its corresponding class. This results in this CL looking very big, but in terms of substance there is not much here. Differential revision: https://reviews.llvm.org/D24834 llvm-svn: 282188

[lldb] Tablegenify thread commands and fix completion bug for thread step-* Beside turning the options into the new tablegen format, this patch also fixes that a few commands had source file completions for the "count" and "end-linenumber" arguments (which both accepted only integers).

Tables of command options in LLDB benefit from hand-formatting to make it easier to scan a set of options with a relatively large number of positional arguments. This commit standardizes their formatting throughout LLDB and applies surrounding directives to exempt them from being formatted by clang-format. These kinds of exemptions should be rare cases that benefit significantly from alternative formatting. They also imply a long-term obligation to maintain their format since the automated tools will not do so. llvm-svn: 279882

Fixed the way set/show variables were being accessed to being natively 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

Add support for custom commands to set flags on themselves This works for Python commands defined via a class (implement get_flags on your class) and C++ plugin commands (which can call SBCommand::GetFlags()/SetFlags()) Flags allow features such as not letting the command run if there's no target, or if the process is not stopped, ... Commands could always check for these things themselves, but having these accessible via flags makes custom commands more consistent with built-in ones llvm-svn: 238286

Add the ability to pass extra args to a Python breakpoint callback. For example, it is pretty easy to write a breakpoint command that implements "stop when my caller is Foo", and it is pretty easy to write a breakpoint command that implements "stop when my caller is Bar". But there's no way to write a generic "stop when my caller is..." function, and then specify the caller when you add the command to a breakpoint. With this patch, you can pass this data in a SBStructuredData dictionary. That will get stored in the PythonCommandBaton for the breakpoint, and passed to the implementation function (if it has the right signature) when the breakpoint is hit. Then in lldb, you can say: (lldb) break com add -F caller_is -k caller_name -v Foo More generally this will allow us to write reusable Python breakpoint commands.

Make raw & parsed commands subclasses of CommandObject rather than having the raw version implement an Execute which was never going to get run and another ExecuteRawCommandString. Took the knowledge of how to prepare raw & parsed commands out of CommandInterpreter and put it in CommandObject where it belongs. Also took all the cases where there were the subcommands of Multiword commands declared in the .h file for the overall command and moved them into the .cpp file. Made the CommandObject flags work for raw as well as parsed commands. Made "expr" use the flags so that it requires you to be paused to run "expr". llvm-svn: 158235

Fixed the way set/show variables were being accessed to being natively 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

But sometimes, e.g. when we are evaluating breakpoint conditions/commands, we don't select the thread we're running on, we instead set the context for the interpreter, and explicitly pass that to other callers. That wasn't getting communicated to these utility expressions, so they would run on some other thread instead, and that could cause a variety of subtle and hard to reproduce problems. I also went through the commands and cleaned up the use of GetSelectedThread. All those uses should have been trying the thread in the m_exe_ctx belonging to the command object first. It would actually have been pretty hard to get misbehavior in these cases, but for correctness sake it is good to make this usage consistent. <rdar://problem/24978569> llvm-svn: 263326

[lldb] Replace StringConvert with llvm::to_integer when parsing integer values in CommandObjects Summary: This replaces the current use of LLDB's own `StringConvert` with LLVM's `to_integer` which has a less error-prone API and doesn't use special 'error values' to designate parsing problems. Where needed I also added missing error handling code that prints a parsing error instead of continuing with the error value returned from `StringConvert` (which either gave a cryptic error message or just took the error value performed an incorrect action with it. For example, `frame recognizer delete -1` just deleted the frame recognizer at index 0).

This is an idea to make "thread step-in --target" work for the common case where you have: 1 -> foo (bar(), 2 baz(), 3 lala()); 4 You are sitting on line 1, and want to step into foo, but not bar, baz & lala. Unfortunately there are line table entries for lines 1-3, and lldb doesn't know anything about the nesting of statement in these lines. So we'll have to use the user's intelligence... This patch adds: (lldb) thread step-in -t foo --end-line 4 That tells lldb to keep stepping in till line 4, but stop if you step into foo. I think I would remember to use this when faced with some of the long gnarly call sequences in lldb. But there might be ways I haven't thought of to make it more convenient. Jason suggests having "end" as a special token for --end-line which just means keep going to the end of the function, I really want to get into this thing... There should be an SB API and tests, which will come if this seems useful. llvm-svn: 260352

This change introduces a "ExpressionExecutionThread" to the ThreadList. Turns out that most of the code that runs expressions (e.g. the ObjC runtime grubber) on behalf of the expression parser was using the currently selected thread. But sometimes, e.g. when we are evaluating breakpoint conditions/commands, we don't select the thread we're running on, we instead set the context for the interpreter, and explicitly pass that to other callers. That wasn't getting communicated to these utility expressions, so they would run on some other thread instead, and that could cause a variety of subtle and hard to reproduce problems. I also went through the commands and cleaned up the use of GetSelectedThread. All those uses should have been trying the thread in the m_exe_ctx belonging to the command object first. It would actually have been pretty hard to get misbehavior in these cases, but for correctness sake it is good to make this usage consistent. <rdar://problem/24978569> llvm-svn: 263326

Add the ability to pass extra args to a Python breakpoint callback. For example, it is pretty easy to write a breakpoint command that implements "stop when my caller is Foo", and it is pretty easy to write a breakpoint command that implements "stop when my caller is Bar". But there's no way to write a generic "stop when my caller is..." function, and then specify the caller when you add the command to a breakpoint. With this patch, you can pass this data in a SBStructuredData dictionary. That will get stored in the PythonCommandBaton for the breakpoint, and passed to the implementation function (if it has the right signature) when the breakpoint is hit. Then in lldb, you can say: (lldb) break com add -F caller_is -k caller_name -v Foo More generally this will allow us to write reusable Python breakpoint commands.

[ScriptInterpreter] Move ownership into debugger (NFC) This is part two of the change started in r359330. This patch moves the ownership of the script interpreter from the command interpreter into the debugger. I would've preferred to remove the lazy initialization, however the fact that the scripting language is set after the debugger is created makes that tricky. So for now this does exactly the same thing as when it was under the command interpreter. The result is that this patch is fully NFC.

Add the ability to pass extra args to a Python breakpoint callback. For example, it is pretty easy to write a breakpoint command that implements "stop when my caller is Foo", and it is pretty easy to write a breakpoint command that implements "stop when my caller is Bar". But there's no way to write a generic "stop when my caller is..." function, and then specify the caller when you add the command to a breakpoint. With this patch, you can pass this data in a SBStructuredData dictionary. That will get stored in the PythonCommandBaton for the breakpoint, and passed to the implementation function (if it has the right signature) when the breakpoint is hit. Then in lldb, you can say: (lldb) break com add -F caller_is -k caller_name -v Foo More generally this will allow us to write reusable Python breakpoint commands.

This checkin is the first step in making the lldb thread stepping mechanism more accessible from the user level. It adds the ability to invent new stepping modes implemented by python classes, and to view the current thread plan stack and to some extent alter it. I haven't gotten to documentation or tests yet.

*** This commit represents a complete reformatting of the LLDB source code *** to conform to clang-format’s LLVM style. This kind of mass change has *** two obvious implications: Firstly, merging this particular commit into a downstream fork may be a huge effort. Alternatively, it may be worth merging all changes up to this commit, performing the same reformatting operation locally, and then discarding the merge for this particular commit. The commands used to accomplish this reformatting were as follows (with current working directory as the root of the repository): find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} + find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ; The version of clang-format used was 3.9.0, and autopep8 was 1.2.4. Secondly, “blame” style tools will generally point to this commit instead of a meaningful prior commit. There are alternatives available that will attempt to look through this change and find the appropriate prior commit. YMMV. llvm-svn: 280751

Add setting to require hardware breakpoints. When debugging read-only memory we cannot use software breakpoint. We already have support for hardware breakpoints and users can specify them with `-H`. However, there's no option to force LLDB to use hardware breakpoints internally, for example while stepping. This patch adds a setting target.require-hardware-breakpoint that forces LLDB to always use hardware breakpoints. Because hardware breakpoints are a limited resource and can fail to resolve, this patch also extends error handling in thread plans, where breakpoints are used for stepping.

This is an idea to make "thread step-in --target" work for the common case where you have: 1 -> foo (bar(), 2 baz(), 3 lala()); 4 You are sitting on line 1, and want to step into foo, but not bar, baz & lala. Unfortunately there are line table entries for lines 1-3, and lldb doesn't know anything about the nesting of statement in these lines. So we'll have to use the user's intelligence...

I think I would remember to use this when faced with some of the long gnarly call sequences in lldb. But there might be ways I haven't thought of to make it more convenient.

However, there's no option to force LLDB to use hardware breakpoints internally, for example while stepping. This patch adds a setting target.require-hardware-breakpoint that forces LLDB to always use hardware breakpoints. Because hardware breakpoints are a limited resource and can fail to resolve, this patch also extends error handling in thread plans, where breakpoints are used for stepping.

Improve LLDB prompt handling Summary: There is an issue in lldb where the command prompt can appear at the wrong time. The partial fix we have in for this is not working all the time and is introducing unnecessary delays. This change does: - Change Process:SyncIOHandler to use integer start id's for synchronization to avoid it being confused by quick start-stop cycles. I picked this up from a suggested patch by Greg to lldb-dev. - coordinates printing of asynchronous text with the iohandlers. This is also based on a (different) Greg's patch, but I have added stronger synchronization to it to avoid races. Together, these changes solve the prompt problem for me on linux (both with and without libedit). I think they should behave similarly on Mac and FreeBSD and I think they will not make matters worse for windows. Test Plan: Prompt comes out alright. All tests still pass on linux.

This allows lldb's fast-step stepping algorithm to potentially run for a longer address range than if we have to stop at every LineEntry indicating a subexpression in the source line. http://reviews.llvm.org/D15407 <rdar://problem/23270882> llvm-svn: 255590

Improve LLDB prompt handling Summary: There is an issue in lldb where the command prompt can appear at the wrong time. The partial fix we have in for this is not working all the time and is introducing unnecessary delays. This change does: - Change Process:SyncIOHandler to use integer start id's for synchronization to avoid it being confused by quick start-stop cycles. I picked this up from a suggested patch by Greg to lldb-dev. - coordinates printing of asynchronous text with the iohandlers. This is also based on a (different) Greg's patch, but I have added stronger synchronization to it to avoid races. Together, these changes solve the prompt problem for me on linux (both with and without libedit). I think they should behave similarly on Mac and FreeBSD and I think they will not make matters worse for windows. Test Plan: Prompt comes out alright. All tests still pass on linux.

Add setting to require hardware breakpoints. When debugging read-only memory we cannot use software breakpoint. We already have support for hardware breakpoints and users can specify them with `-H`. However, there's no option to force LLDB to use hardware breakpoints internally, for example while stepping. This patch adds a setting target.require-hardware-breakpoint that forces LLDB to always use hardware breakpoints. Because hardware breakpoints are a limited resource and can fail to resolve, this patch also extends error handling in thread plans, where breakpoints are used for stepping.

That was needed to fix a bug where the ThreadPlanStepInRange wasn't checking with its sub-plans to make sure they succeed before trying to proceed further.

This checkin is the first step in making the lldb thread stepping mechanism more accessible from the user level. It adds the ability to invent new stepping modes implemented by python classes, and to view the current thread plan stack and to some extent alter it. I haven't gotten to documentation or tests yet.

Rename Error -> Status. This renames the LLDB error class to Status, as discussed on the lldb-dev mailing list. A change of this magnitude cannot easily be done without find and replace, but that has potential to catch unwanted occurrences of common strings such as "Error". Every effort was made to find all the obvious things such as the word "Error" appearing in a string, etc, but it's possible there are still some lingering occurences left around. Hopefully nothing too serious. llvm-svn: 302872

Re-land r313210 - Fix for bug 34532 - A few rough corners related to post-mortem debugging (core/minidump) The main change is to avoid setting the process state as running when debugging core/minidumps (details in the bug). Also included a few small, related fixes around how the errors propagate in this case. Fixed the FreeBSD/Windows break: the intention was to keep Process::WillResume() and Process::DoResume() "in-sync", but this had the unfortunate consequence of breaking Process sub-classes which don't override WillResume(). The safer approach is to keep Process::WillResume() untouched and only override it in the minidump and core implementations. patch by lemo Bug: https://bugs.llvm.org/show_bug.cgi?id=34532 Differential Revision: https://reviews.llvm.org/D37651 llvm-svn: 313655

Modernize and clean-up the Predicate class Summary: The comments on this class were out of date with the implementation, and the implementation itself was inconsistent with our usage of the Timeout class (I started converting everything to use this class back in D27136, but I missed this one). I avoid duplicating the waiting logic by introducing a templated WaitFor function, and make other functions delegate to that. This function can be also used as a replacement for the unused WaitForBitToBeSet functions I removed, if it turns out to be necessary. As this changes the meaning of a "zero" timeout, I tracked down all the callers of these functions and updated them accordingly. Propagating the changes to all the callers of RunShellCommand was a bit too much for this patch, so I stopped there and will continue that in a follow-up patch. I also add some basic unittests for the functions I modified. Reviewers: jingham, clayborg Subscribers: mgorny, lldb-commits Differential Revision: https://reviews.llvm.org/D46580 llvm-svn: 331880

Don't allow direct access to StreamString's internal buffer. This is a large API change that removes the two functions from StreamString that return a std::string& and a const std::string&, and instead provide one function which returns a StringRef.

Clean up the usage of "MasterPlan" status in ThreadPlans. Only user-initiated plans should be MasterPlans that want to stay on the plan stack. So make all plans NOT MasterPlans by default and then have the SB API's and the CommandObjectThread step commands set this explicitly. Also added a "clean up" phase to the Thread::ShouldStop so that if plans get stranded on the stack, we can remove them. This is done by adding an IsPlanStale method to the thread plans, and if the plan can know that it is no longer relevant, it returns true, and the plan and its sub-plans will get discarded. llvm-svn: 156101

Add setting to require hardware breakpoints. When debugging read-only memory we cannot use software breakpoint. We already have support for hardware breakpoints and users can specify them with `-H`. However, there's no option to force LLDB to use hardware breakpoints internally, for example while stepping. This patch adds a setting target.require-hardware-breakpoint that forces LLDB to always use hardware breakpoints. Because hardware breakpoints are a limited resource and can fail to resolve, this patch also extends error handling in thread plans, where breakpoints are used for stepping.

Make raw & parsed commands subclasses of CommandObject rather than having the raw version implement an Execute which was never going to get run and another ExecuteRawCommandString. Took the knowledge of how to prepare raw & parsed commands out of CommandInterpreter and put it in CommandObject where it belongs. Also took all the cases where there were the subcommands of Multiword commands declared in the .h file for the overall command and moved them into the .cpp file. Made the CommandObject flags work for raw as well as parsed commands. Made "expr" use the flags so that it requires you to be paused to run "expr". llvm-svn: 158235

Fixed the way set/show variables were being accessed to being natively 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

Make the "synchronous" mode actually work without race conditions. There were many issues with synchronous mode that we discovered when started to try and add a "batch" mode. There was a race condition where the event handling thread might consume events when in sync mode and other times the Process::WaitForProcessToStop() would consume them. This also led to places where the Process IO handler might or might not get popped when it needed to be. llvm-svn: 220254

This change introduces a "ExpressionExecutionThread" to the ThreadList. Turns out that most of the code that runs expressions (e.g. the ObjC runtime grubber) on behalf of the expression parser was using the currently selected thread. But sometimes, e.g. when we are evaluating breakpoint conditions/commands, we don't select the thread we're running on, we instead set the context for the interpreter, and explicitly pass that to other callers. That wasn't getting communicated to these utility expressions, so they would run on some other thread instead, and that could cause a variety of subtle and hard to reproduce problems. I also went through the commands and cleaned up the use of GetSelectedThread. All those uses should have been trying the thread in the m_exe_ctx belonging to the command object first. It would actually have been pretty hard to get misbehavior in these cases, but for correctness sake it is good to make this usage consistent. <rdar://problem/24978569> llvm-svn: 263326

A change of this magnitude cannot easily be done without find and replace, but that has potential to catch unwanted occurrences of common strings such as "Error".

Tables of command options in LLDB benefit from hand-formatting to make it easier to scan a set of options with a relatively large number of positional arguments. This commit standardizes their formatting throughout LLDB and applies surrounding directives to exempt them from being formatted by clang-format. These kinds of exemptions should be rare cases that benefit significantly from alternative formatting. They also imply a long-term obligation to maintain their format since the automated tools will not do so. llvm-svn: 279882

Make the "synchronous" mode actually work without race conditions. There were many issues with synchronous mode that we discovered when started to try and add a "batch" mode. There was a race condition where the event handling thread might consume events when in sync mode and other times the Process::WaitForProcessToStop() would consume them. This also led to places where the Process IO handler might or might not get popped when it needed to be. llvm-svn: 220254

Don't allow direct access to StreamString's internal buffer. This is a large API change that removes the two functions from StreamString that return a std::string& and a const std::string&, and instead provide one function which returns a StringRef. Direct access to the underlying buffer violates the concept of a "stream" which is intended to provide forward only access, and makes porting to llvm::raw_ostream more difficult in the future.

This checkin is the first step in making the lldb thread stepping mechanism more accessible from the user level. It adds the ability to invent new stepping modes implemented by python classes, and to view the current thread plan stack and to some extent alter it. I haven't gotten to documentation or tests yet. But this should not cause any behavior changes if you don't use it, so its safe to check it in now and work on it incrementally. llvm-svn: 218642

Convert option tables to ArrayRefs. This change is very mechanical. All it does is change the signature of `Options::GetDefinitions()` and `OptionGroup:: GetDefinitions()` to return an `ArrayRef<OptionDefinition>` instead of a `const OptionDefinition *`. In the case of the former, it deletes the sentinel entry from every table, and in the case of the latter, it removes the `GetNumDefinitions()` method from the interface. These are no longer necessary as `ArrayRef` carries its own length. In the former case, iteration was done by using a sentinel entry, so there was no knowledge of length. Because of this the individual option tables were allowed to be defined below the corresponding class (after all, only a pointer was needed). Now, however, the length must be known at compile time to construct the `ArrayRef`, and as a result it is necessary to move every option table before its corresponding class. This results in this CL looking very big, but in terms of substance there is not much here. Differential revision: https://reviews.llvm.org/D24834 llvm-svn: 282188

Make raw & parsed commands subclasses of CommandObject rather than having the raw version implement an Execute which was never going to get run and another ExecuteRawCommandString. Took the knowledge of how to prepare raw & parsed commands out of CommandInterpreter and put it in CommandObject where it belongs. Also took all the cases where there were the subcommands of Multiword commands declared in the .h file for the overall command and moved them into the .cpp file. Made the CommandObject flags work for raw as well as parsed commands. Made "expr" use the flags so that it requires you to be paused to run "expr". llvm-svn: 158235

Re-organized the contents of RangeMap.h to be more concise and also allow for a Range, RangeArray, RangeData (range + data), or a RangeDataArray. We have many range implementations in LLDB and I will be converting over to using the classes in RangeMap.h so we can have one set of code that does ranges and searching of ranges. Fixed up DWARFDebugAranges to use the new range classes. Fixed the enumeration parsing to take a lldb_private::Error to avoid a lot of duplicated code. Now when an invalid enumeration is supplied, an error will be returned and that error will contain a list of the valid enumeration values. llvm-svn: 141382

[lldb][NFC] Remove dead code that is supposed to handle invalid command options Summary: We currently have a bunch of code that is supposed to handle invalid command options, but all this code is unreachable because invalid options are already handled in `Options::Parse`. The only way we can reach this code is when we declare but then not implement an option (which will be made impossible with D65386, which is also when we can completely remove the `default` cases). This patch replaces all this code with `llvm_unreachable` to make clear this is dead code that can't be reached.

Convert option tables to ArrayRefs. This change is very mechanical. All it does is change the signature of `Options::GetDefinitions()` and `OptionGroup:: GetDefinitions()` to return an `ArrayRef<OptionDefinition>` instead of a `const OptionDefinition *`. In the case of the former, it deletes the sentinel entry from every table, and in the case of the latter, it removes the `GetNumDefinitions()` method from the interface. These are no longer necessary as `ArrayRef` carries its own length. In the former case, iteration was done by using a sentinel entry, so there was no knowledge of length. Because of this the individual option tables were allowed to be defined below the corresponding class (after all, only a pointer was needed). Now, however, the length must be known at compile time to construct the `ArrayRef`, and as a result it is necessary to move every option table before its corresponding class. This results in this CL looking very big, but in terms of substance there is not much here. Differential revision: https://reviews.llvm.org/D24834 llvm-svn: 282188

// Instance variables to hold the values for command options.
Fixed the way set/show variables were being accessed to being natively 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

[lldb] Unify target checking in CommandObject Summary: We currently have several CommandObjects that manually reimplement the checking for a selected target or a target in the execution context (which is the selected target when they are invoked). This patch removes all these checks and replaces them by setting the eCommandRequiresTarget flag that Pavel suggested. With this flag we are doing the same check but without having to duplicate this code in all these CommandObjects. I also added a `GetSelectedTarget()` variant of the `GetSelectedOrDummyTarget()` function to the CommandObject that checks that the flag is set and then returns a reference to the target. I didn't rewrite all the `target` variables from `Target *` to `Target &` in this patch as last time this change caused a lot of merge conflicts in Swift and I would prefer having that in a separate NFC commit.

[lldb] Replace StringConvert with llvm::to_integer when parsing integer values in CommandObjects Summary: This replaces the current use of LLDB's own `StringConvert` with LLVM's `to_integer` which has a less error-prone API and doesn't use special 'error values' to designate parsing problems. Where needed I also added missing error handling code that prints a parsing error instead of continuing with the error value returned from `StringConvert` (which either gave a cryptic error message or just took the error value performed an incorrect action with it. For example, `frame recognizer delete -1` just deleted the frame recognizer at index 0).

This change introduces a "ExpressionExecutionThread" to the ThreadList. Turns out that most of the code that runs expressions (e.g. the ObjC runtime grubber) on behalf of the expression parser was using the currently selected thread. But sometimes, e.g. when we are evaluating breakpoint conditions/commands, we don't select the thread we're running on, we instead set the context for the interpreter, and explicitly pass that to other callers. That wasn't getting communicated to these utility expressions, so they would run on some other thread instead, and that could cause a variety of subtle and hard to reproduce problems. I also went through the commands and cleaned up the use of GetSelectedThread. All those uses should have been trying the thread in the m_exe_ctx belonging to the command object first. It would actually have been pretty hard to get misbehavior in these cases, but for correctness sake it is good to make this usage consistent. <rdar://problem/24978569> llvm-svn: 263326

That was needed to fix a bug where the ThreadPlanStepInRange wasn't checking with its sub-plans to make sure they succeed before trying to proceed further.

Add setting to require hardware breakpoints. When debugging read-only memory we cannot use software breakpoint. We already have support for hardware breakpoints and users can specify them with `-H`. However, there's no option to force LLDB to use hardware breakpoints internally, for example while stepping. This patch adds a setting target.require-hardware-breakpoint that forces LLDB to always use hardware breakpoints. Because hardware breakpoints are a limited resource and can fail to resolve, this patch also extends error handling in thread plans, where breakpoints are used for stepping.

Tables of command options in LLDB benefit from hand-formatting to make it easier to scan a set of options with a relatively large number of positional arguments. This commit standardizes their formatting throughout LLDB and applies surrounding directives to exempt them from being formatted by clang-format. These kinds of exemptions should be rare cases that benefit significantly from alternative formatting. They also imply a long-term obligation to maintain their format since the automated tools will not do so. llvm-svn: 279882

[lldb] Remove FileSpec->CompileUnit inheritance Summary: CompileUnit is a complicated class. Having it be implicitly convertible to a FileSpec makes reasoning about it even harder. This patch replaces the inheritance by a simple member and an accessor function. This avoid the need for casting in places where one needed to force a CompileUnit to be treated as a FileSpec, and does not add much verbosity elsewhere. It also fixes a bug where we were wrongly comparing CompileUnit& and a CompileUnit*, which compiled due to a combination of this inheritance and the FileSpec*->FileSpec implicit constructor.

Make the "synchronous" mode actually work without race conditions. There were many issues with synchronous mode that we discovered when started to try and add a "batch" mode. There was a race condition where the event handling thread might consume events when in sync mode and other times the Process::WaitForProcessToStop() would consume them. This also led to places where the Process IO handler might or might not get popped when it needed to be. llvm-svn: 220254

Rename Error -> Status. This renames the LLDB error class to Status, as discussed on the lldb-dev mailing list. A change of this magnitude cannot easily be done without find and replace, but that has potential to catch unwanted occurrences of common strings such as "Error". Every effort was made to find all the obvious things such as the word "Error" appearing in a string, etc, but it's possible there are still some lingering occurences left around. Hopefully nothing too serious. llvm-svn: 302872

Don't allow direct access to StreamString's internal buffer. This is a large API change that removes the two functions from StreamString that return a std::string& and a const std::string&, and instead provide one function which returns a StringRef. Direct access to the underlying buffer violates the concept of a "stream" which is intended to provide forward only access, and makes porting to llvm::raw_ostream more difficult in the future.

Fix deadlock due to thread list locking in 'bt all' with obj-c Summary: The gdb-remote async thread cannot modify thread state while the main thread holds a lock on the state. Don't use locking thread iteration for bt all. Specifically, the deadlock manifests when lldb attempts to JIT code to symbolicate objective c while backtracing. As part of this code path, SetPrivateState() is called on an async thread. This async thread will block waiting for the thread_list lock held by the main thread in CommandObjectIterateOverThreads. The main thread will also block on the async thread during DoResume (although with a timeout), leading to a deadlock. Due to the timeout, the deadlock is not immediately apparent, but the inferior will be left in an invalid state after the bt all completes, and objective-c symbols will not be successfully resolved in the backtrace.

[lldb] Replace StringConvert with llvm::to_integer when parsing integer values in CommandObjects Summary: This replaces the current use of LLDB's own `StringConvert` with LLVM's `to_integer` which has a less error-prone API and doesn't use special 'error values' to designate parsing problems. Where needed I also added missing error handling code that prints a parsing error instead of continuing with the error value returned from `StringConvert` (which either gave a cryptic error message or just took the error value performed an incorrect action with it. For example, `frame recognizer delete -1` just deleted the frame recognizer at index 0).

There were many logic errors in the DoExecute function where thread index IDs were being used where the actual zero based thread index should have been used.

The validity of the target objects in m_exe_ctx are checked to ensure that any target/process/thread/frame/reg context that are required are valid prior to executing the command. Each command object also contains a Mutex::Locker m_api_locker which gets used if eFlagTryTargetAPILock is set. This centralizes a lot of checking code that was previously and inconsistently implemented across many commands. llvm-svn: 171990

It adds the ability to invent new stepping modes implemented by python classes, and to view the current thread plan stack and to some extent alter it. I haven't gotten to documentation or tests yet. But this should not cause any behavior changes if you don't use it, so its safe to check it in now and work on it incrementally. llvm-svn: 218642

Very large changes that were needed in order to allow multiple connections to the debugger from GUI windows. Previously there was one global debugger instance that could be accessed that had its own command interpreter and current state (current target/process/thread/frame). When a GUI debugger was attached, if it opened more than one window that each had a console window, there were issues where the last one to setup the global debugger object won and got control of the debugger. To avoid this we now create instances of the lldb_private::Debugger that each has its own state: - target list for targets the debugger instance owns - current process/thread/frame - its own command interpreter - its own input, output and error file handles to avoid conflicts - its own input reader stack So now clients should call: SBDebugger::Initialize(); // (static function) SBDebugger debugger (SBDebugger::Create()); // Use which ever file handles you wish debugger.SetErrorFileHandle (stderr, false); debugger.SetOutputFileHandle (stdout, false); debugger.SetInputFileHandle (stdin, true); // main loop SBDebugger::Terminate(); // (static function) SBDebugger::Initialize() and SBDebugger::Terminate() are ref counted to ensure nothing gets destroyed too early when multiple clients might be attached.

Initial merge of some of the iOS 8 / Mac OS X Yosemite specific lldb support. I'll be doing more testing & cleanup but I wanted to get the initial checkin done. This adds a new SBExpressionOptions::SetLanguage API for selecting a language of an expression. I added adds a new SBThread::GetInfoItemByPathString for retriving information about a thread from that thread's StructuredData. I added a new StructuredData class for representing key-value/array/dictionary information (e.g. JSON formatted data). Helper functions to read JSON and create a StructuredData object, and to print a StructuredData object in JSON format are included. A few Cocoa / Cocoa Touch data formatters were updated by Enrico to track changes in iOS 8 / Yosemite. Before we query a thread's extended information, the system runtime may provide hints to the remote debug stub that it will use to retrieve values out of runtime structures. I added a new SystemRuntime method AddThreadExtendedInfoPacketHints which allows the SystemRuntime to add key-value type data to the initial request that we send to the remote stub. The thread-format formatter string can now retrieve values out of a thread's extended info structured data. The default thread-format string picks up two of these - thread.info.activity.name and thread.info.trace_messages. I added a new "jThreadExtendedInfo" packet in debugserver; I will add documentation to the lldb-gdb-remote.txt doc soon. It accepts JSON formatted arguments (most importantly, "thread":threadnum) and it returns a variety of information regarding the thread to lldb in JSON format. This JSON return is scanned into a StructuredData object that is associated with the thread; UI layers can query the thread's StructuredData to see if key-values are present, and if so, show them to the user. These key-values are likely to be specific to different targets with some commonality among many targets. For instance, many targets will be able to advertise the pthread_t value for a thread. I added an initial rough cut of "thread info" command which will print the information about a thread from the jThreadExtendedInfo result. I need to do more work to make this format reasonably. Han Ming added calls into the pmenergy and pmsample libraries if debugserver is run on Mac OS X Yosemite to get information about the inferior's power use. I added support to debugserver for gathering the Genealogy information about threads, if it exists, and returning it in the jThreadExtendedInfo JSON result. llvm-svn: 210874

[lldb] Tablegenify thread commands and fix completion bug for thread step-* Beside turning the options into the new tablegen format, this patch also fixes that a few commands had source file completions for the "count" and "end-linenumber" arguments (which both accepted only integers).

Convert option tables to ArrayRefs. This change is very mechanical. All it does is change the signature of `Options::GetDefinitions()` and `OptionGroup:: GetDefinitions()` to return an `ArrayRef<OptionDefinition>` instead of a `const OptionDefinition *`. In the case of the former, it deletes the sentinel entry from every table, and in the case of the latter, it removes the `GetNumDefinitions()` method from the interface. These are no longer necessary as `ArrayRef` carries its own length. In the former case, iteration was done by using a sentinel entry, so there was no knowledge of length. Because of this the individual option tables were allowed to be defined below the corresponding class (after all, only a pointer was needed). Now, however, the length must be known at compile time to construct the `ArrayRef`, and as a result it is necessary to move every option table before its corresponding class.

This checkin is the first step in making the lldb thread stepping mechanism more accessible from the user level. It adds the ability to invent new stepping modes implemented by python classes, and to view the current thread plan stack and to some extent alter it. I haven't gotten to documentation or tests yet. But this should not cause any behavior changes if you don't use it, so its safe to check it in now and work on it incrementally. llvm-svn: 218642

The thread-format formatter string can now retrieve values out of a thread's extended info structured data.

I added a new "jThreadExtendedInfo" packet in debugserver; I will add documentation to the lldb-gdb-remote.txt doc soon. It accepts JSON formatted arguments (most importantly, "thread":threadnum) and it returns a variety of information regarding the thread to lldb in JSON format. This JSON return is scanned into a StructuredData object that is associated with the thread; UI layers can query the thread's StructuredData to see if key-values are present, and if so, show them to the user. These key-values are likely to be specific to different targets with some commonality among many targets. For instance, many targets will be able to advertise the pthread_t value for a thread.

LLDB AddressSanitizer instrumentation runtime plugin, breakpint on error and report data extraction Reviewed at http://reviews.llvm.org/D5592 This patch gives LLDB some ability to interact with AddressSanitizer runtime library, on top of what we already have (historical memory stack traces provided by ASan). Namely, that's the ability to stop on an error caught by ASan, and access the report information that are associated with it. The report information is also exposed into SB API. More precisely this patch... adds a new plugin type, InstrumentationRuntime, which should serve as a generic superclass for other instrumentation runtime libraries, these plugins get notified when modules are loaded, so they get a chance to "activate" when a specific dynamic library is loaded an instance of this plugin type, AddressSanitizerRuntime, which activates itself when it sees the ASan dynamic library or founds ASan statically linked in the executable adds a collection of these plugins into the Process class AddressSanitizerRuntime sets an internal breakpoint on __asan::AsanDie(), and when this breakpoint gets hit, it retrieves the report information from ASan this breakpoint is then exposed as a new StopReason, eStopReasonInstrumentation, with a new StopInfo subclass, InstrumentationRuntimeStopInfo the StopInfo superclass is extended with a m_extended_info field (it's a StructuredData::ObjectSP), that can hold arbitrary JSON-like data, which is the way the new plugin provides the report data the "thread info" command now accepts a "-s" flag that prints out the JSON data of a stop reason (same way the "-j" flag works now) SBThread has a new API, GetStopReasonExtendedInfoAsJSON, which dumps the JSON string into a SBStream adds a test case for all of this I plan to also get rid of the original ASan plugin (memory history stack traces) and use an instance of AddressSanitizerRuntime for that purpose.

[lldb][NFC] Remove dead code that is supposed to handle invalid command options Summary: We currently have a bunch of code that is supposed to handle invalid command options, but all this code is unreachable because invalid options are already handled in `Options::Parse`. The only way we can reach this code is when we declare but then not implement an option (which will be made impossible with D65386, which is also when we can completely remove the `default` cases). This patch replaces all this code with `llvm_unreachable` to make clear this is dead code that can't be reached.

*** This commit represents a complete reformatting of the LLDB source code *** to conform to clang-format’s LLVM style. This kind of mass change has *** two obvious implications: Firstly, merging this particular commit into a downstream fork may be a huge effort. Alternatively, it may be worth merging all changes up to this commit, performing the same reformatting operation locally, and then discarding the merge for this particular commit. The commands used to accomplish this reformatting were as follows (with current working directory as the root of the repository): find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} + find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ; The version of clang-format used was 3.9.0, and autopep8 was 1.2.4. Secondly, “blame” style tools will generally point to this commit instead of a meaningful prior commit. There are alternatives available that will attempt to look through this change and find the appropriate prior commit. YMMV. llvm-svn: 280751

Convert option tables to ArrayRefs. This change is very mechanical. All it does is change the signature of `Options::GetDefinitions()` and `OptionGroup:: GetDefinitions()` to return an `ArrayRef<OptionDefinition>` instead of a `const OptionDefinition *`. In the case of the former, it deletes the sentinel entry from every table, and in the case of the latter, it removes the `GetNumDefinitions()` method from the interface. These are no longer necessary as `ArrayRef` carries its own length. In the former case, iteration was done by using a sentinel entry, so there was no knowledge of length. Because of this the individual option tables were allowed to be defined below the corresponding class (after all, only a pointer was needed). Now, however, the length must be known at compile time to construct the `ArrayRef`, and as a result it is necessary to move every option table before its corresponding class. This results in this CL looking very big, but in terms of substance there is not much here. Differential revision: https://reviews.llvm.org/D24834 llvm-svn: 282188

Convert option tables to ArrayRefs. This change is very mechanical. All it does is change the signature of `Options::GetDefinitions()` and `OptionGroup:: GetDefinitions()` to return an `ArrayRef<OptionDefinition>` instead of a `const OptionDefinition *`. In the case of the former, it deletes the sentinel entry from every table, and in the case of the latter, it removes the `GetNumDefinitions()` method from the interface.

LLDB AddressSanitizer instrumentation runtime plugin, breakpint on error and report data extraction Reviewed at http://reviews.llvm.org/D5592 This patch gives LLDB some ability to interact with AddressSanitizer runtime library, on top of what we already have (historical memory stack traces provided by ASan). Namely, that's the ability to stop on an error caught by ASan, and access the report information that are associated with it. The report information is also exposed into SB API. More precisely this patch... adds a new plugin type, InstrumentationRuntime, which should serve as a generic superclass for other instrumentation runtime libraries, these plugins get notified when modules are loaded, so they get a chance to "activate" when a specific dynamic library is loaded an instance of this plugin type, AddressSanitizerRuntime, which activates itself when it sees the ASan dynamic library or founds ASan statically linked in the executable adds a collection of these plugins into the Process class AddressSanitizerRuntime sets an internal breakpoint on __asan::AsanDie(), and when this breakpoint gets hit, it retrieves the report information from ASan this breakpoint is then exposed as a new StopReason, eStopReasonInstrumentation, with a new StopInfo subclass, InstrumentationRuntimeStopInfo the StopInfo superclass is extended with a m_extended_info field (it's a StructuredData::ObjectSP), that can hold arbitrary JSON-like data, which is the way the new plugin provides the report data the "thread info" command now accepts a "-s" flag that prints out the JSON data of a stop reason (same way the "-j" flag works now) SBThread has a new API, GetStopReasonExtendedInfoAsJSON, which dumps the JSON string into a SBStream adds a test case for all of this I plan to also get rid of the original ASan plugin (memory history stack traces) and use an instance of AddressSanitizerRuntime for that purpose.

Initial merge of some of the iOS 8 / Mac OS X Yosemite specific lldb support. I'll be doing more testing & cleanup but I wanted to get the initial checkin done. This adds a new SBExpressionOptions::SetLanguage API for selecting a language of an expression. I added adds a new SBThread::GetInfoItemByPathString for retriving information about a thread from that thread's StructuredData. I added a new StructuredData class for representing key-value/array/dictionary information (e.g. JSON formatted data). Helper functions to read JSON and create a StructuredData object, and to print a StructuredData object in JSON format are included. A few Cocoa / Cocoa Touch data formatters were updated by Enrico to track changes in iOS 8 / Yosemite. Before we query a thread's extended information, the system runtime may provide hints to the remote debug stub that it will use to retrieve values out of runtime structures. I added a new SystemRuntime method AddThreadExtendedInfoPacketHints which allows the SystemRuntime to add key-value type data to the initial request that we send to the remote stub. The thread-format formatter string can now retrieve values out of a thread's extended info structured data. The default thread-format string picks up two of these - thread.info.activity.name and thread.info.trace_messages. I added a new "jThreadExtendedInfo" packet in debugserver; I will add documentation to the lldb-gdb-remote.txt doc soon. It accepts JSON formatted arguments (most importantly, "thread":threadnum) and it returns a variety of information regarding the thread to lldb in JSON format. This JSON return is scanned into a StructuredData object that is associated with the thread; UI layers can query the thread's StructuredData to see if key-values are present, and if so, show them to the user. These key-values are likely to be specific to different targets with some commonality among many targets. For instance, many targets will be able to advertise the pthread_t value for a thread. I added an initial rough cut of "thread info" command which will print the information about a thread from the jThreadExtendedInfo result. I need to do more work to make this format reasonably. Han Ming added calls into the pmenergy and pmsample libraries if debugserver is run on Mac OS X Yosemite to get information about the inferior's power use. I added support to debugserver for gathering the Genealogy information about threads, if it exists, and returning it in the jThreadExtendedInfo JSON result. llvm-svn: 210874

Initial merge of some of the iOS 8 / Mac OS X Yosemite specific lldb support. I'll be doing more testing & cleanup but I wanted to get the initial checkin done. This adds a new SBExpressionOptions::SetLanguage API for selecting a language of an expression. I added adds a new SBThread::GetInfoItemByPathString for retriving information about a thread from that thread's StructuredData. I added a new StructuredData class for representing key-value/array/dictionary information (e.g. JSON formatted data). Helper functions to read JSON and create a StructuredData object, and to print a StructuredData object in JSON format are included. A few Cocoa / Cocoa Touch data formatters were updated by Enrico to track changes in iOS 8 / Yosemite. Before we query a thread's extended information, the system runtime may provide hints to the remote debug stub that it will use to retrieve values out of runtime structures. I added a new SystemRuntime method AddThreadExtendedInfoPacketHints which allows the SystemRuntime to add key-value type data to the initial request that we send to the remote stub. The thread-format formatter string can now retrieve values out of a thread's extended info structured data. The default thread-format string picks up two of these - thread.info.activity.name and thread.info.trace_messages. I added a new "jThreadExtendedInfo" packet in debugserver; I will add documentation to the lldb-gdb-remote.txt doc soon. It accepts JSON formatted arguments (most importantly, "thread":threadnum) and it returns a variety of information regarding the thread to lldb in JSON format. This JSON return is scanned into a StructuredData object that is associated with the thread; UI layers can query the thread's StructuredData to see if key-values are present, and if so, show them to the user. These key-values are likely to be specific to different targets with some commonality among many targets. For instance, many targets will be able to advertise the pthread_t value for a thread. I added an initial rough cut of "thread info" command which will print the information about a thread from the jThreadExtendedInfo result. I need to do more work to make this format reasonably. Han Ming added calls into the pmenergy and pmsample libraries if debugserver is run on Mac OS X Yosemite to get information about the inferior's power use. I added support to debugserver for gathering the Genealogy information about threads, if it exists, and returning it in the jThreadExtendedInfo JSON result. llvm-svn: 210874

Convert option tables to ArrayRefs. This change is very mechanical. All it does is change the signature of `Options::GetDefinitions()` and `OptionGroup:: GetDefinitions()` to return an `ArrayRef<OptionDefinition>` instead of a `const OptionDefinition *`. In the case of the former, it deletes the sentinel entry from every table, and in the case of the latter, it removes the `GetNumDefinitions()` method from the interface. These are no longer necessary as `ArrayRef` carries its own length. In the former case, iteration was done by using a sentinel entry, so there was no knowledge of length. Because of this the individual option tables were allowed to be defined below the corresponding class (after all, only a pointer was needed). Now, however, the length must be known at compile time to construct the `ArrayRef`, and as a result it is necessary to move every option table before its corresponding class. This results in this CL looking very big, but in terms of substance there is not much here. Differential revision: https://reviews.llvm.org/D24834 llvm-svn: 282188

This results in this CL looking very big, but in terms of substance there is not much here. Differential revision: https://reviews.llvm.org/D24834 llvm-svn: 282188

Convert option tables to ArrayRefs. This change is very mechanical. All it does is change the signature of `Options::GetDefinitions()` and `OptionGroup:: GetDefinitions()` to return an `ArrayRef<OptionDefinition>` instead of a `const OptionDefinition *`. In the case of the former, it deletes the sentinel entry from every table, and in the case of the latter, it removes the `GetNumDefinitions()` method from the interface. These are no longer necessary as `ArrayRef` carries its own length. In the former case, iteration was done by using a sentinel entry, so there was no knowledge of length. Because of this the individual option tables were allowed to be defined below the corresponding class (after all, only a pointer was needed). Now, however, the length must be known at compile time to construct the `ArrayRef`, and as a result it is necessary to move every option table before its corresponding class.

This checkin is the first step in making the lldb thread stepping mechanism more accessible from the user level. It adds the ability to invent new stepping modes implemented by python classes, and to view the current thread plan stack and to some extent alter it. I haven't gotten to documentation or tests yet. But this should not cause any behavior changes if you don't use it, so its safe to check it in now and work on it incrementally. llvm-svn: 218642

Rename Error -> Status. This renames the LLDB error class to Status, as discussed on the lldb-dev mailing list. A change of this magnitude cannot easily be done without find and replace, but that has potential to catch unwanted occurrences of common strings such as "Error".

Expanded the flags that can be set for a command object in lldb_private::CommandObject.

If a process doesn't exist or is invalid, the command // will fail and CommandObject::GetInvalidProcessDescription() will be // returned as the error. CommandObject subclasses can override the // virtual function for GetInvalidProcessDescription() to provide custom // strings when needed. //---------------------------------------------------------------------- eFlagRequiresProcess = (1u << 1), //---------------------------------------------------------------------- // eFlagRequiresThread // // Ensures a valid thread is contained in m_exe_ctx prior to executing // the command. If a thread doesn't exist or is invalid, the command // will fail and CommandObject::GetInvalidThreadDescription() will be // returned as the error. CommandObject subclasses can override the // virtual function for GetInvalidThreadDescription() to provide custom // strings when needed. //---------------------------------------------------------------------- eFlagRequiresThread = (1u << 2), //---------------------------------------------------------------------- // eFlagRequiresFrame // // Ensures a valid frame is contained in m_exe_ctx prior to executing // the command. If a frame doesn't exist or is invalid, the command // will fail and CommandObject::GetInvalidFrameDescription() will be // returned as the error. CommandObject subclasses can override the // virtual function for GetInvalidFrameDescription() to provide custom // strings when needed. //---------------------------------------------------------------------- eFlagRequiresFrame = (1u << 3), //---------------------------------------------------------------------- // eFlagRequiresRegContext // // Ensures a valid register context (from the selected frame if there // is a frame in m_exe_ctx, or from the selected thread from m_exe_ctx) // is availble from m_exe_ctx prior to executing the command. If a // target doesn't exist or is invalid, the command will fail and // CommandObject::GetInvalidRegContextDescription() will be returned as // the error.

The validity of the target objects in m_exe_ctx are checked to ensure that any target/process/thread/frame/reg context that are required are valid prior to executing the command. Each command object also contains a Mutex::Locker m_api_locker which gets used if eFlagTryTargetAPILock is set. This centralizes a lot of checking code that was previously and inconsistently implemented across many commands. llvm-svn: 171990

ThreadSP thread_sp = m_exe_ctx.GetThreadSP();
Change the Thread constructor over to take a Process& rather than a 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

This checkin is the first step in making the lldb thread stepping mechanism more accessible from the user level. It adds the ability to invent new stepping modes implemented by python classes, and to view the current thread plan stack and to some extent alter it. I haven't gotten to documentation or tests yet. But this should not cause any behavior changes if you don't use it, so its safe to check it in now and work on it incrementally. llvm-svn: 218642

Convert option tables to ArrayRefs. This change is very mechanical. All it does is change the signature of `Options::GetDefinitions()` and `OptionGroup:: GetDefinitions()` to return an `ArrayRef<OptionDefinition>` instead of a `const OptionDefinition *`. In the case of the former, it deletes the sentinel entry from every table, and in the case of the latter, it removes the `GetNumDefinitions()` method from the interface. These are no longer necessary as `ArrayRef` carries its own length. In the former case, iteration was done by using a sentinel entry, so there was no knowledge of length. Because of this the individual option tables were allowed to be defined below the corresponding class (after all, only a pointer was needed). Now, however, the length must be known at compile time to construct the `ArrayRef`, and as a result it is necessary to move every option table before its corresponding class. This results in this CL looking very big, but in terms of substance there is not much here. Differential revision: https://reviews.llvm.org/D24834 llvm-svn: 282188

Rename Error -> Status. This renames the LLDB error class to Status, as discussed on the lldb-dev mailing list. A change of this magnitude cannot easily be done without find and replace, but that has potential to catch unwanted occurrences of common strings such as "Error". Every effort was made to find all the obvious things such as the word "Error" appearing in a string, etc, but it's possible there are still some lingering occurences left around. Hopefully nothing too serious. llvm-svn: 302872

Move Args::StringTo*** functions to a new OptionArgParser class Summary: The idea behind this is to move the functionality which depend on other lldb classes into a separate class.

[lldb][NFC] Remove dead code that is supposed to handle invalid command options Summary: We currently have a bunch of code that is supposed to handle invalid command options, but all this code is unreachable because invalid options are already handled in `Options::Parse`. The only way we can reach this code is when we declare but then not implement an option (which will be made impossible with D65386, which is also when we can completely remove the `default` cases). This patch replaces all this code with `llvm_unreachable` to make clear this is dead code that can't be reached.

Convert option tables to ArrayRefs. This change is very mechanical. All it does is change the signature of `Options::GetDefinitions()` and `OptionGroup:: GetDefinitions()` to return an `ArrayRef<OptionDefinition>` instead of a `const OptionDefinition *`. In the case of the former, it deletes the sentinel entry from every table, and in the case of the latter, it removes the `GetNumDefinitions()` method from the interface. These are no longer necessary as `ArrayRef` carries its own length. In the former case, iteration was done by using a sentinel entry, so there was no knowledge of length. Because of this the individual option tables were allowed to be defined below the corresponding class (after all, only a pointer was needed). Now, however, the length must be known at compile time to construct the `ArrayRef`, and as a result it is necessary to move every option table before its corresponding class. This results in this CL looking very big, but in terms of substance there is not much here. Differential revision: https://reviews.llvm.org/D24834 llvm-svn: 282188

Tables of command options in LLDB benefit from hand-formatting to make it easier to scan a set of options with a relatively large number of positional arguments. This commit standardizes their formatting throughout LLDB and applies surrounding directives to exempt them from being formatted by clang-format.

They also imply a long-term obligation to maintain their format since the automated tools will not do so. llvm-svn: 279882

Convert option tables to ArrayRefs. This change is very mechanical. All it does is change the signature of `Options::GetDefinitions()` and `OptionGroup:: GetDefinitions()` to return an `ArrayRef<OptionDefinition>` instead of a `const OptionDefinition *`. In the case of the former, it deletes the sentinel entry from every table, and in the case of the latter, it removes the `GetNumDefinitions()` method from the interface. These are no longer necessary as `ArrayRef` carries its own length. In the former case, iteration was done by using a sentinel entry, so there was no knowledge of length. Because of this the individual option tables were allowed to be defined below the corresponding class (after all, only a pointer was needed). Now, however, the length must be known at compile time to construct the `ArrayRef`, and as a result it is necessary to move every option table before its corresponding class. This results in this CL looking very big, but in terms of substance there is not much here. Differential revision: https://reviews.llvm.org/D24834 llvm-svn: 282188

[lldb][NFC] Remove dead code that is supposed to handle invalid command options Summary: We currently have a bunch of code that is supposed to handle invalid command options, but all this code is unreachable because invalid options are already handled in `Options::Parse`. The only way we can reach this code is when we declare but then not implement an option (which will be made impossible with D65386, which is also when we can completely remove the `default` cases). This patch replaces all this code with `llvm_unreachable` to make clear this is dead code that can't be reached.

In the case of the former, it deletes the sentinel entry from every table, and in the case of the latter, it removes the `GetNumDefinitions()` method from the interface. These are no longer necessary as `ArrayRef` carries its own length. In the former case, iteration was done by using a sentinel entry, so there was no knowledge of length. Because of this the individual option tables were allowed to be defined below the corresponding class (after all, only a pointer was needed). Now, however, the length must be known at compile time to construct the `ArrayRef`, and as a result it is necessary to move every option table before its corresponding class. This results in this CL looking very big, but in terms of substance there is not much here. Differential revision: https://reviews.llvm.org/D24834 llvm-svn: 282188

Fix deadlock due to thread list locking in 'bt all' with obj-c Summary: The gdb-remote async thread cannot modify thread state while the main thread holds a lock on the state. Don't use locking thread iteration for bt all. Specifically, the deadlock manifests when lldb attempts to JIT code to symbolicate objective c while backtracing. As part of this code path, SetPrivateState() is called on an async thread. This async thread will block waiting for the thread_list lock held by the main thread in CommandObjectIterateOverThreads. The main thread will also block on the async thread during DoResume (although with a timeout), leading to a deadlock. Due to the timeout, the deadlock is not immediately apparent, but the inferior will be left in an invalid state after the bt all completes, and objective-c symbols will not be successfully resolved in the backtrace.

It's similar to the example python script in examples/python/jump.py, except implemented as a builtin. Also this version will track the current function correctly even if the target line resolves to multiple addresses. (e.g. debugging a templated function) llvm-svn: 190572

[lldb] Replace StringConvert with llvm::to_integer when parsing integer values in CommandObjects Summary: This replaces the current use of LLDB's own `StringConvert` with LLVM's `to_integer` which has a less error-prone API and doesn't use special 'error values' to designate parsing problems. Where needed I also added missing error handling code that prints a parsing error instead of continuing with the error value returned from `StringConvert` (which either gave a cryptic error message or just took the error value performed an incorrect action with it. For example, `frame recognizer delete -1` just deleted the frame recognizer at index 0).

*** This commit represents a complete reformatting of the LLDB source code *** to conform to clang-format’s LLVM style. This kind of mass change has *** two obvious implications: Firstly, merging this particular commit into a downstream fork may be a huge effort. Alternatively, it may be worth merging all changes up to this commit, performing the same reformatting operation locally, and then discarding the merge for this particular commit. The commands used to accomplish this reformatting were as follows (with current working directory as the root of the repository): find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} + find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ; The version of clang-format used was 3.9.0, and autopep8 was 1.2.4. Secondly, “blame” style tools will generally point to this commit instead of a meaningful prior commit. There are alternatives available that will attempt to look through this change and find the appropriate prior commit. YMMV. llvm-svn: 280751

I noticed that it was a required step to mimic how core-based processes are initialized, e.g. ProcessElfCore and ProcessMinidump. I haven't had the need to create ThreadTrace yet, though. So far HistoryThread seems good enough. - The command handling itself in CommandObjectThread, which outputs a placeholder text instead of the actual instructions.

This diff implements the corresponding cursor class for Intel PT and deletes the now obsolete code. Besides that, the logic for the "thread trace dump instructions" was adapted to use this cursor (pretty much I ended up moving code from Trace.cpp to TraceCursor.cpp). The command by default traverses the instructions backwards, and if the user passes --forwards, then it's not forwards. More information about that is in the Options.td file. Regarding the Intel PT cursor. All Intel PT cursors for the same thread share the same DecodedThread instance. I'm not yet implementing lazy decoding because we don't need it. That'll be for later.

Changes: - Added an IntelPTDecoder class, that is a wrapper for libipt, which is the actual library that performs the decoding. - Added TraceThreadDecoder class that decodes traces and memoizes the result to avoid repeating the decoding step. - Added a DecodedThread class, which represents the output from decoding and that for the time being only stores the list of reconstructed instructions. Later it'll contain the function call hierarchy, which will enable reconstructing backtraces. - Added basic APIs for accessing the trace in Trace.h: - GetInstructionCount, which counts the number of instructions traced for a given thread - IsTraceFailed, which returns an Error if decoding a thread failed - ForEachInstruction, which iterates on the instructions traced for a given thread, concealing the internal storage of threads, as plug-ins can decide to generate the instructions on the fly or to store them all in a vector, like I do. - DumpTraceInstructions was updated to print the instructions or show an error message if decoding was impossible. - Tests included Differential Revision: https://reviews.llvm.org/D89283

[trace][intel pt] Support events A trace might contain events traced during the target's execution. For example, a thread might be paused for some period of time due to context switches or breakpoints, which actually force a context switch. Not only that, a trace might be paused because the CPU decides to trace only a specific part of the target, like the address filtering provided by intel pt, which will cause pause events. Besides this case, other kinds of events might exist. This patch adds the method `TraceCursor::GetEvents()`` that returns the list of events that happened right before the instruction being pointed at by the cursor. Some refactors were done to make this change simpler. Besides this new API, the instruction dumper now supports the -e flag which shows pause events, like in the following example, where pauses happened due to breakpoints. ``` thread #1: tid = 2717361 a.out`main + 20 at main.cpp:27:20 0: 0x00000000004023d9 leaq -0x1200(%rbp), %rax [paused] 1: 0x00000000004023e0 movq %rax, %rdi [paused] 2: 0x00000000004023e3 callq 0x403a62 ; std::vector<int, std::allocator<int> >::vector at stl_vector.h:391:7 a.out`std::vector<int, std::allocator<int> >::vector() at stl_vector.h:391:7 3: 0x0000000000403a62 pushq %rbp 4: 0x0000000000403a63 movq %rsp, %rbp ``` The `dump info` command has also been updated and now it shows the number of instructions that have associated events.

Add a repeat command option for "thread backtrace --count N". This way if you have a long stack, you can issue "thread backtrace --count 10" and then subsequent <Return>-s will page you through the stack. This took a little more effort than just adding the repeat command, since the GetRepeatCommand API was returning a "const char *". That meant the command had to keep the repeat string alive, which is inconvenient. The original API returned either a nullptr, or a const char *, so I changed the private API to return an llvm::Optional<std::string>. Most of the patch is propagating that change. Also, there was a little thinko in fetching the repeat command. We don't fetch repeat commands for commands that aren't being added to history, which is in general reasonable. And we don't add repeat commands to the history - also reasonable. But we do want the repeat command to be able to generate the NEXT repeat command. So I adjusted the logic in HandleCommand to work that way. Differential Revision: https://reviews.llvm.org/D119046

[trace][intel-pt] Scaffold the 'thread trace start | stop' commands Depends on D90490. The stop command is simple and invokes the new method Trace::StopTracingThread(thread). On the other hand, the start command works by delegating its implementation to a CommandObject provided by the Trace plugin. This is necessary because each trace plugin needs different options for this command. There's even the chance that a Trace plugin can't support live tracing, but instead supports offline decoding and analysis, which means that "thread trace dump instructions" works but "thread trace start" doest. Because of this and a few other reasons, it's better to have each plugin provide this implementation. Besides, I'm using the GetSupportedTraceType method introduced in D90490 to quickly infer what's the trace plug-in that works for the current process. As an implementation note, I moved CommandObjectIterateOverThreads to its header so that I can use it from the IntelPT plugin. Besides, the actual start and stop logic for intel-pt is not part of this diff. Reviewed By: clayborg Differential Revision: https://reviews.llvm.org/D90729

[trace] Add the definition of a TraceExporter plugin Copying from the inline documentation: ``` Trace exporter plug-ins operate on traces, converting the trace data provided by an \a lldb_private::TraceCursor into a different format that can be digested by other tools, e.g. Chrome Trace Event Profiler. Trace exporters are supposed to operate on an architecture-agnostic fashion, as a TraceCursor, which feeds the data, hides the actual trace technology being used. ``` I want to use this to make the code in https://reviews.llvm.org/D105741 a plug-in. I also imagine that there will be more and more exporters being implemented, as an exporter creates something useful out of trace data. And tbh I don't want to keep adding more stuff to the lldb/Target folder. This is the minimal definition for a TraceExporter plugin. I plan to use this with the following commands: - thread trace export <plug-in name> [plug-in specific args] - This command would support autocompletion of plug-in names - thread trace export list - This command would list the available trace exporter plug-ins I don't plan to create yet a "process trace export" because it's easier to start analyzing the trace of a given thread than of the entire process. When we need a process-level command, we can implement it. I also don't plan to force each "export" command implementation to support multiple threads (for example, "thread trace start 1 2 3" or "thread trace start all" operate on many threads simultaneously). The reason is that the format used by the exporter might or might not support multiple threads, so I'm leaving this decision to each trace exporter plug-in.

Initial merge of some of the iOS 8 / Mac OS X Yosemite specific lldb support. I'll be doing more testing & cleanup but I wanted to get the initial checkin done. This adds a new SBExpressionOptions::SetLanguage API for selecting a language of an expression. I added adds a new SBThread::GetInfoItemByPathString for retriving information about a thread from that thread's StructuredData. I added a new StructuredData class for representing key-value/array/dictionary information (e.g. JSON formatted data). Helper functions to read JSON and create a StructuredData object, and to print a StructuredData object in JSON format are included. A few Cocoa / Cocoa Touch data formatters were updated by Enrico to track changes in iOS 8 / Yosemite. Before we query a thread's extended information, the system runtime may provide hints to the remote debug stub that it will use to retrieve values out of runtime structures. I added a new SystemRuntime method AddThreadExtendedInfoPacketHints which allows the SystemRuntime to add key-value type data to the initial request that we send to the remote stub. The thread-format formatter string can now retrieve values out of a thread's extended info structured data. The default thread-format string picks up two of these - thread.info.activity.name and thread.info.trace_messages. I added a new "jThreadExtendedInfo" packet in debugserver; I will add documentation to the lldb-gdb-remote.txt doc soon. It accepts JSON formatted arguments (most importantly, "thread":threadnum) and it returns a variety of information regarding the thread to lldb in JSON format. This JSON return is scanned into a StructuredData object that is associated with the thread; UI layers can query the thread's StructuredData to see if key-values are present, and if so, show them to the user. These key-values are likely to be specific to different targets with some commonality among many targets. For instance, many targets will be able to advertise the pthread_t value for a thread. I added an initial rough cut of "thread info" command which will print the information about a thread from the jThreadExtendedInfo result. I need to do more work to make this format reasonably. Han Ming added calls into the pmenergy and pmsample libraries if debugserver is run on Mac OS X Yosemite to get information about the inferior's power use. I added support to debugserver for gathering the Genealogy information about threads, if it exists, and returning it in the jThreadExtendedInfo JSON result. llvm-svn: 210874

*** This commit represents a complete reformatting of the LLDB source code *** to conform to clang-format’s LLVM style.

Alternatively, it may be worth merging all changes up to this commit, performing the same reformatting operation locally, and then discarding the merge for this particular commit. The commands used to accomplish this reformatting were as follows (with current working directory as the root of the repository): find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} + find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ; The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.

This checkin is the first step in making the lldb thread stepping mechanism more accessible from the user level. It adds the ability to invent new stepping modes implemented by python classes, and to view the current thread plan stack and to some extent alter it. I haven't gotten to documentation or tests yet. But this should not cause any behavior changes if you don't use it, so its safe to check it in now and work on it incrementally. llvm-svn: 218642

[trace] Scaffold "thread trace dump instructions" Depends on D88841 As per the discussion in the RFC, we'll implement both thread trace dump [instructions | functions] This is the first step in implementing the "instructions" dumping command. It includes: - A minimal ProcessTrace plugin for representing processes from a trace file. I noticed that it was a required step to mimic how core-based processes are initialized, e.g. ProcessElfCore and ProcessMinidump. I haven't had the need to create ThreadTrace yet, though. So far HistoryThread seems good enough. - The command handling itself in CommandObjectThread, which outputs a placeholder text instead of the actual instructions. I'll do that part in the next diff. - Tests {F13132325} Differential Revision: https://reviews.llvm.org/D88769
