<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

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

Modified the ArchSpec to take an optional "Platform *" when setting the triple. This allows you to have a platform selected, then specify a triple using "i386" and have the remaining triple items (vendor, os, and environment) set automatically. Many interpreter commands take the "--arch" option to specify an architecture triple, so now the command options needed to be able to get to the current platform, so the Options class now take a reference to the interpreter on construction. Modified the build LLVM building in the Xcode project to use the new Xcode project level user definitions: LLVM_BUILD_DIR - a path to the llvm build directory LLVM_SOURCE_DIR - a path to the llvm sources for the llvm that will be used to build lldb LLVM_CONFIGURATION - the configuration that lldb is built for (Release, Release+Asserts, Debug, Debug+Asserts). I also changed the LLVM build to not check if "lldb/llvm" is a symlink and then assume it is a real llvm build directory versus the unzipped llvm.zip package, so now you can actually have a "lldb/llvm" directory in your lldb sources. llvm-svn: 129112

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.

<rdar://problem/12798131> Cleaned up the option parsing code to always pass around the short options as integers. Previously we cast this down to "char" and lost some information. I recently added an assert that would detect duplicate short character options which was firing during the test suite. This fix does the following: - make sure all short options are treated as "int" - make sure that short options can be non-printable values when a short option is not required or when an option group is mixed into many commands and a short option is not desired - fix the help printing to "do the right thing" in all cases. Previously if there were duplicate short character options, it would just not emit help for the duplicates - fix option parsing when there are duplicates to parse options correctly. Previously the option parsing, when done for an OptionGroup, would just start parsing options incorrectly by omitting table entries and it would end up setting the wrong option value llvm-svn: 169189

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

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

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.

Modified the ArchSpec to take an optional "Platform *" when setting the triple. This allows you to have a platform selected, then specify a triple using "i386" and have the remaining triple items (vendor, os, and environment) set automatically. Many interpreter commands take the "--arch" option to specify an architecture triple, so now the command options needed to be able to get to the current platform, so the Options class now take a reference to the interpreter on construction. Modified the build LLVM building in the Xcode project to use the new Xcode project level user definitions: LLVM_BUILD_DIR - a path to the llvm build directory LLVM_SOURCE_DIR - a path to the llvm sources for the llvm that will be used to build lldb LLVM_CONFIGURATION - the configuration that lldb is built for (Release, Release+Asserts, Debug, Debug+Asserts). I also changed the LLVM build to not check if "lldb/llvm" is a symlink and then assume it is a real llvm build directory versus the unzipped llvm.zip package, so now you can actually have a "lldb/llvm" directory in your lldb sources. llvm-svn: 129112

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

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. Cleaned up the command interpreter and the CommandObject and all subclasses to take more appropriate arguments. llvm-svn: 106615

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

Modified the ArchSpec to take an optional "Platform *" when setting the triple. This allows you to have a platform selected, then specify a triple using "i386" and have the remaining triple items (vendor, os, and environment) set automatically. Many interpreter commands take the "--arch" option to specify an architecture triple, so now the command options needed to be able to get to the current platform, so the Options class now take a reference to the interpreter on construction. Modified the build LLVM building in the Xcode project to use the new Xcode project level user definitions: LLVM_BUILD_DIR - a path to the llvm build directory LLVM_SOURCE_DIR - a path to the llvm sources for the llvm that will be used to build lldb LLVM_CONFIGURATION - the configuration that lldb is built for (Release, Release+Asserts, Debug, Debug+Asserts). I also changed the LLVM build to not check if "lldb/llvm" is a symlink and then assume it is a real llvm build directory versus the unzipped llvm.zip package, so now you can actually have a "lldb/llvm" directory in your lldb sources. llvm-svn: 129112

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

<rdar://problem/12798131> Cleaned up the option parsing code to always pass around the short options as integers. Previously we cast this down to "char" and lost some information. I recently added an assert that would detect duplicate short character options which was firing during the test suite. This fix does the following: - make sure all short options are treated as "int" - make sure that short options can be non-printable values when a short option is not required or when an option group is mixed into many commands and a short option is not desired - fix the help printing to "do the right thing" in all cases. Previously if there were duplicate short character options, it would just not emit help for the duplicates - fix option parsing when there are duplicates to parse options correctly. Previously the option parsing, when done for an OptionGroup, would just start parsing options incorrectly by omitting table entries and it would end up setting the wrong option value llvm-svn: 169189

This commit reworks how the thread plan's ShouldStopHere mechanism works, so that it is useful not only for customizing "step-in" behavior (e.g. step-in doesn't step into code with no debug info), but also the behavior of step-in/step-out and step-over when they step out of the frame they started in. I also added as a proof of concept of this reworking a mode for stepping where stepping out of a frame into a frame with no debug information will continue stepping out till it arrives at a frame that does have debug information. This is useful when you are debugging callback based code where the callbacks are separated from the code that initiated them by some library glue you don't care about, among other things. llvm-svn: 203747

This commit reworks how the thread plan's ShouldStopHere mechanism works, so that it is useful not only for customizing "step-in" behavior (e.g. step-in doesn't step into code with no debug info), but also the behavior of step-in/step-out and step-over when they step out of the frame they started in. I also added as a proof of concept of this reworking a mode for stepping where stepping out of a frame into a frame with no debug information will continue stepping out till it arrives at a frame that does have debug information. This is useful when you are debugging callback based code where the callbacks are separated from the code that initiated them by some library glue you don't care about, among other things. llvm-svn: 203747

Add an "Avoid Frames matching this regular expression" to ThreadPlanStepInRange. This relies on ThreadPlanStepOut working correctly, which it doesn't currently for Inlined functions, so this feature is only partially useful until we take care of Stepping Out of inlined functions. Added an option to "thread step-in" to set the avoid regular expression. This is mostly for testing, once the Setting code is redone, we'll move this to a general setting. llvm-svn: 108036

Fixed a few bugs in the "step in" thread plan logic. Added a "step-in-target" flag to "thread step-in" so if you have something like: Process 28464 stopped * thread #1: tid = 0x1c03, function: main , stop reason = breakpoint 1.1 frame #0: 0x0000000100000e08 a.out`main at main.c:62 61 -> 62 int A6 = complex (a(4), b(5), c(6)); // Stop here to step targetting b and hitting breakpoint. 63 and you want to get into "complex" skipping a, b and c, you can do: (lldb) step -t complex Process 28464 stopped * thread #1: tid = 0x1c03, function: complex , stop reason = step in frame #0: 0x0000000100000d0d a.out`complex at main.c:44 41 42 int complex (int first, int second, int third) 43 { -> 44 return first + second + third; // Step in targetting complex should stop here 45 } 46 47 int main (int argc, char const *argv[]) llvm-svn: 170008

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

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

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

Modified the ArchSpec to take an optional "Platform *" when setting the triple. This allows you to have a platform selected, then specify a triple using "i386" and have the remaining triple items (vendor, os, and environment) set automatically. Many interpreter commands take the "--arch" option to specify an architecture triple, so now the command options needed to be able to get to the current platform, so the Options class now take a reference to the interpreter on construction. Modified the build LLVM building in the Xcode project to use the new Xcode project level user definitions: LLVM_BUILD_DIR - a path to the llvm build directory LLVM_SOURCE_DIR - a path to the llvm sources for the llvm that will be used to build lldb LLVM_CONFIGURATION - the configuration that lldb is built for (Release, Release+Asserts, Debug, Debug+Asserts). I also changed the LLVM build to not check if "lldb/llvm" is a symlink and then assume it is a real llvm build directory versus the unzipped llvm.zip package, so now you can actually have a "lldb/llvm" directory in your lldb sources. llvm-svn: 129112

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

This commit does two things. One, it converts the return value of the QueueThreadPlanXXX plan providers from a "ThreadPlan *" to a "lldb::ThreadPlanSP". 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. If the sub-plan failed and as a result didn't make any progress, you could end up retrying the same failing algorithm in an infinite loop. <rdar://problem/14043602> llvm-svn: 186618

This commit reworks how the thread plan's ShouldStopHere mechanism works, so that it is useful not only for customizing "step-in" behavior (e.g. step-in doesn't step into code with no debug info), but also the behavior of step-in/step-out and step-over when they step out of the frame they started in. I also added as a proof of concept of this reworking a mode for stepping where stepping out of a frame into a frame with no debug information will continue stepping out till it arrives at a frame that does have debug information. This is useful when you are debugging callback based code where the callbacks are separated from the code that initiated them by some library glue you don't care about, among other things. llvm-svn: 203747

This commit does two things. One, it converts the return value of the QueueThreadPlanXXX plan providers from a "ThreadPlan *" to a "lldb::ThreadPlanSP". 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. If the sub-plan failed and as a result didn't make any progress, you could end up retrying the same failing algorithm in an infinite loop. <rdar://problem/14043602> llvm-svn: 186618

This commit reworks how the thread plan's ShouldStopHere mechanism works, so that it is useful not only for customizing "step-in" behavior (e.g. step-in doesn't step into code with no debug info), but also the behavior of step-in/step-out and step-over when they step out of the frame they started in. I also added as a proof of concept of this reworking a mode for stepping where stepping out of a frame into a frame with no debug information will continue stepping out till it arrives at a frame that does have debug information. This is useful when you are debugging callback based code where the callbacks are separated from the code that initiated them by some library glue you don't care about, among other things. llvm-svn: 203747

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

This commit reworks how the thread plan's ShouldStopHere mechanism works, so that it is useful not only for customizing "step-in" behavior (e.g. step-in doesn't step into code with no debug info), but also the behavior of step-in/step-out and step-over when they step out of the frame they started in. I also added as a proof of concept of this reworking a mode for stepping where stepping out of a frame into a frame with no debug information will continue stepping out till it arrives at a frame that does have debug information. This is useful when you are debugging callback based code where the callbacks are separated from the code that initiated them by some library glue you don't care about, among other things. llvm-svn: 203747

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

This commit does two things. One, it converts the return value of the QueueThreadPlanXXX plan providers from a "ThreadPlan *" to a "lldb::ThreadPlanSP". 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. If the sub-plan failed and as a result didn't make any progress, you could end up retrying the same failing algorithm in an infinite loop. <rdar://problem/14043602> llvm-svn: 186618

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

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

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

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

Modified the ArchSpec to take an optional "Platform *" when setting the triple. This allows you to have a platform selected, then specify a triple using "i386" and have the remaining triple items (vendor, os, and environment) set automatically. Many interpreter commands take the "--arch" option to specify an architecture triple, so now the command options needed to be able to get to the current platform, so the Options class now take a reference to the interpreter on construction. Modified the build LLVM building in the Xcode project to use the new Xcode project level user definitions: LLVM_BUILD_DIR - a path to the llvm build directory LLVM_SOURCE_DIR - a path to the llvm sources for the llvm that will be used to build lldb LLVM_CONFIGURATION - the configuration that lldb is built for (Release, Release+Asserts, Debug, Debug+Asserts). I also changed the LLVM build to not check if "lldb/llvm" is a symlink and then assume it is a real llvm build directory versus the unzipped llvm.zip package, so now you can actually have a "lldb/llvm" directory in your lldb sources. llvm-svn: 129112

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.

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.

<rdar://problem/12798131> Cleaned up the option parsing code to always pass around the short options as integers. Previously we cast this down to "char" and lost some information. I recently added an assert that would detect duplicate short character options which was firing during the test suite. This fix does the following: - make sure all short options are treated as "int" - make sure that short options can be non-printable values when a short option is not required or when an option group is mixed into many commands and a short option is not desired - fix the help printing to "do the right thing" in all cases. Previously if there were duplicate short character options, it would just not emit help for the duplicates - fix option parsing when there are duplicates to parse options correctly. Previously the option parsing, when done for an OptionGroup, would just start parsing options incorrectly by omitting table entries and it would end up setting the wrong option value llvm-svn: 169189

Expanded the flags that can be set for a command object in lldb_private::CommandObject. This list of available flags are: enum { //---------------------------------------------------------------------- // eFlagRequiresTarget // // Ensures a valid target is contained in m_exe_ctx prior to executing // the command. If a target doesn't exist or is invalid, the command // will fail and CommandObject::GetInvalidTargetDescription() will be // returned as the error. CommandObject subclasses can override the // virtual function for GetInvalidTargetDescription() to provide custom // strings when needed. //---------------------------------------------------------------------- eFlagRequiresTarget = (1u << 0), //---------------------------------------------------------------------- // eFlagRequiresProcess // // Ensures a valid process is contained in m_exe_ctx prior to executing // the command. 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. CommandObject subclasses can override the virtual function // for GetInvalidRegContextDescription() to provide custom strings when // needed. //---------------------------------------------------------------------- eFlagRequiresRegContext = (1u << 4), //---------------------------------------------------------------------- // eFlagTryTargetAPILock // // Attempts to acquire the target lock if a target is selected in the // command interpreter. If the command object fails to acquire the API // lock, the command will fail with an appropriate error message. //---------------------------------------------------------------------- eFlagTryTargetAPILock = (1u << 5), //---------------------------------------------------------------------- // eFlagProcessMustBeLaunched // // Verifies that there is a launched process in m_exe_ctx, if there // isn't, the command will fail with an appropriate error message. //---------------------------------------------------------------------- eFlagProcessMustBeLaunched = (1u << 6), //---------------------------------------------------------------------- // eFlagProcessMustBePaused // // Verifies that there is a paused process in m_exe_ctx, if there // isn't, the command will fail with an appropriate error message. //---------------------------------------------------------------------- eFlagProcessMustBePaused = (1u << 7) }; Now each command object contains a "ExecutionContext m_exe_ctx;" member variable that gets initialized prior to running the command. 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

Modified the ArchSpec to take an optional "Platform *" when setting the triple. This allows you to have a platform selected, then specify a triple using "i386" and have the remaining triple items (vendor, os, and environment) set automatically. Many interpreter commands take the "--arch" option to specify an architecture triple, so now the command options needed to be able to get to the current platform, so the Options class now take a reference to the interpreter on construction. Modified the build LLVM building in the Xcode project to use the new Xcode project level user definitions: LLVM_BUILD_DIR - a path to the llvm build directory LLVM_SOURCE_DIR - a path to the llvm sources for the llvm that will be used to build lldb LLVM_CONFIGURATION - the configuration that lldb is built for (Release, Release+Asserts, Debug, Debug+Asserts). I also changed the LLVM build to not check if "lldb/llvm" is a symlink and then assume it is a real llvm build directory versus the unzipped llvm.zip package, so now you can actually have a "lldb/llvm" directory in your lldb sources. llvm-svn: 129112

Added new OptionGroup classes for UInt64, UUID, File and Boolean values. Removed the "image" command and moved it to "target modules". Added an alias for "image" to "target modules". Added some new target commands to be able to add and load modules to a target: (lldb) target modules add <path> (lldb) target modules load [--file <path>] [--slide <offset>] [<sect-name> <sect-load-addr> ...] So you can load individual sections without running a target: (lldb) target modules load --file /usr/lib/libSystem.B.dylib __TEXT 0x7fccc80000 __DATA 0x1234000000 Or you can rigidly slide an entire shared library: (lldb) target modules load --file /usr/lib/libSystem.B.dylib --slid 0x7fccc80000 This should improve bare board debugging when symbol files need to be slid around manually. llvm-svn: 130796

Expanded the flags that can be set for a command object in lldb_private::CommandObject. This list of available flags are: enum { //---------------------------------------------------------------------- // eFlagRequiresTarget // // Ensures a valid target is contained in m_exe_ctx prior to executing // the command. If a target doesn't exist or is invalid, the command // will fail and CommandObject::GetInvalidTargetDescription() will be // returned as the error. CommandObject subclasses can override the // virtual function for GetInvalidTargetDescription() to provide custom // strings when needed. //---------------------------------------------------------------------- eFlagRequiresTarget = (1u << 0), //---------------------------------------------------------------------- // eFlagRequiresProcess // // Ensures a valid process is contained in m_exe_ctx prior to executing // the command. 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. CommandObject subclasses can override the virtual function // for GetInvalidRegContextDescription() to provide custom strings when // needed. //---------------------------------------------------------------------- eFlagRequiresRegContext = (1u << 4), //---------------------------------------------------------------------- // eFlagTryTargetAPILock // // Attempts to acquire the target lock if a target is selected in the // command interpreter.

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

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

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 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

- Changed all the places where CommandObjectReturn was exporting a StreamString to just exporting a Stream, and then added GetOutputData & GetErrorData to get the accumulated data. - Added a StreamTee that will tee output to two provided lldb::StreamSP's. - Made the CommandObjectReturn use this so you can Tee the results immediately to the debuggers output file, as well as saving up the results to return when the command is done executing. - HandleCommands now uses this so that if you have a set of commands that continue the target you will see the commands come out as they are processed. - The Driver now uses this to output the command results as you go, which makes the interface more reactive seeming. llvm-svn: 126015

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. CommandObject subclasses can override the virtual function // for GetInvalidRegContextDescription() to provide custom strings when // needed. //---------------------------------------------------------------------- eFlagRequiresRegContext = (1u << 4), //---------------------------------------------------------------------- // eFlagTryTargetAPILock // // Attempts to acquire the target lock if a target is selected in the // command interpreter.

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

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 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

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.

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.

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 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

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

Roll back the changes I made in r193907 which created a new Frame pure virtual base class and made StackFrame a subclass of that. As I started to build on top of that arrangement today, I found that it wasn't working out like I intended.

Roll back the changes I made in r193907 which created a new Frame pure virtual base class and made StackFrame a subclass of that. As I started to build on top of that arrangement today, I found that it wasn't working out like I intended.

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

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.

Fixed up all CommandObjects to take an interpreter and cleaned up the API to not need the interpreter to be passed 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

To avoid this we now create instances of the lldb_private::Debugger that each has its own state: - target list for targets the debugger instance owns - current process/thread/frame - its own command interpreter - its own input, output and error file handles to avoid conflicts - its own input reader stack So now clients should call: SBDebugger::Initialize(); // (static function) SBDebugger debugger (SBDebugger::Create()); // Use which ever file handles you wish debugger.SetErrorFileHandle (stderr, false); debugger.SetOutputFileHandle (stdout, false); debugger.SetInputFileHandle (stdin, true); // main loop SBDebugger::Terminate(); // (static function) SBDebugger::Initialize() and SBDebugger::Terminate() are ref counted to ensure nothing gets destroyed too early when multiple clients might be attached. Cleaned up the command interpreter and the CommandObject and all subclasses to take more appropriate arguments. llvm-svn: 106615

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

Very large changes that were needed in order to allow multiple connections to the debugger from GUI windows.

Add the ability to capture the return value in a thread's stop info, and print it as part of the thread format output. Currently this is only done for the ThreadPlanStepOut. Add a convenience API ABI::GetReturnValueObject. Change the ValueObject::EvaluationPoint to BE an ExecutionContextScope, rather than trying to hand out one of its subsidiary object's pointers. That way this will always be good. llvm-svn: 146806

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
