Added a user-settable variable, 'target.expr-prefix', which holds the name of a file whose contents are prefixed to each expression. For example, if the file ~/lldb.prefix.header contains: typedef unsigned short my_type; then you can do this: (lldb) settings set target.expr-prefix '~/lldb.prefix.header' (lldb) expr sizeof(my_type) (unsigned long) $0 = 2 When the variable is changed, the corresponding file is loaded and its contents are fetched into a string that is stored along with the target. This string is then passed to each expression and inserted into it during parsing, like this: typedef unsigned short my_type; void $__lldb_expr(void *$__lldb_arg) { sizeof(my_type); } llvm-svn: 117627

#include "lldb/Core/DataBufferMemoryMap.h"
Modified LLDB expressions to not have to JIT and run code just to see variable values or persistent expression variables. Now if an expression consists of a value that is a child of a variable, or of a persistent variable only, we will create a value object for it and make a ValueObjectConstResult from it to freeze the value (for program variables only, not persistent variables) and avoid running JITed code. For everything else we still parse up and JIT code and run it in the inferior. There was also a lot of clean up in the expression code. I made the ClangExpressionVariables be stored in collections of shared pointers instead of in collections of objects. This will help stop a lot of copy constructors on these large objects and also cleans up the code considerably. The persistent clang expression variables were moved over to the Target to ensure they persist across process executions. Added the ability for lldb_private::Target objects to evaluate expressions. We want to evaluate expressions at the target level in case we aren't running yet, or we have just completed running. We still want to be able to access the persistent expression variables between runs, and also evaluate constant expressions. Added extra logging to the dynamic loader plug-in for MacOSX. ModuleList objects can now dump their contents with the UUID, arch and full paths being logged with appropriate prefix values. Thread hardened the Communication class a bit by making the connection auto_ptr member into a shared pointer member and then making a local copy of the shared pointer in each method that uses it to make sure another thread can't nuke the connection object while it is being used by another thread. Added a new file to the lldb/test/load_unload test that causes the test a.out file to link to the libd.dylib file all the time. This will allow us to test using the DYLD_LIBRARY_PATH environment variable after moving libd.dylib somewhere else. llvm-svn: 121745

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

Modified all logging calls to hand out shared pointers to make sure we don't crash if we disable logging when some code already has a copy of the logger. Prior to this fix, logs were handed out as pointers and if they were held onto while a log got disabled, then it could cause a crash. Now all logs are handed out as shared pointers so this problem shouldn't happen anymore. We are also using our new shared pointers that put the shared pointer count and the object into the same allocation for a tad better performance. llvm-svn: 118319

First pass at adding logging capabilities for the API functions. At the moment it logs the function calls, their arguments and the return values. This is not complete or polished, but I am committing it now, at the request of someone who really wants to use it, even though it's not really done. It currently does not attempt to log all the functions, just the most important ones. I will be making further adjustments to the API logging code over the next few days/weeks. (Suggestions for improvements are welcome). Update the Python build scripts to re-build the swig C++ file whenever the python-extensions.swig file is modified. Correct the help for 'log enable' command (give it the correct number & type of arguments). llvm-svn: 117349

Added support for inlined stack frames being represented as real stack frames which is now on by default. Frames are gotten from the unwinder as concrete frames, then if inline frames are to be shown, extra information to track and reconstruct these frames is cached with each Thread and exanded as needed. I added an inline height as part of the lldb_private::StackID class, the class that helps us uniquely identify stack frames. This allows for two frames to shared the same call frame address, yet differ only in inline height. Fixed setting breakpoint by address to not require addresses to resolve. A quick example: % cat main.cpp % ./build/Debug/lldb test/stl/a.out Current executable set to 'test/stl/a.out' (x86_64).

I added an inline height as part of the lldb_private::StackID class, the class that helps us uniquely identify stack frames. This allows for two frames to shared the same call frame address, yet differ only in inline height. Fixed setting breakpoint by address to not require addresses to resolve. A quick example: % cat main.cpp % ./build/Debug/lldb test/stl/a.out Current executable set to 'test/stl/a.out' (x86_64).

Added function name types to allow us to set breakpoints by name more intelligently. The four name types we currently have are: eFunctionNameTypeFull = (1 << 1), // The function name. // For C this is the same as just the name of the function // For C++ this is the demangled version of the mangled name. // For ObjC this is the full function signature with the + or // - and the square brackets and the class and selector eFunctionNameTypeBase = (1 << 2), // The function name only, no namespaces or arguments and no class // methods or selectors will be searched. eFunctionNameTypeMethod = (1 << 3), // Find function by method name (C++) with no namespace or arguments eFunctionNameTypeSelector = (1 << 4) // Find function by selector name (ObjC) names this allows much more flexibility when setting breakoints: (lldb) breakpoint set --name main --basename (lldb) breakpoint set --name main --fullname (lldb) breakpoint set --name main --method (lldb) breakpoint set --name main --selector The default: (lldb) breakpoint set --name main will inspect the name "main" and look for any parens, or if the name starts with "-[" or "+[" and if any are found then a full name search will happen. Else a basename search will be the default. Fixed some command option structures so not all options are required when they shouldn't be. Cleaned up the breakpoint output summary. Made the "image lookup --address <addr>" output much more verbose so it shows all the important symbol context results.

Modified all logging calls to hand out shared pointers to make sure we don't crash if we disable logging when some code already has a copy of the logger. Prior to this fix, logs were handed out as pointers and if they were held onto while a log got disabled, then it could cause a crash. Now all logs are handed out as shared pointers so this problem shouldn't happen anymore.

Added a new Host call to find LLDB related paths: static bool Host::GetLLDBPath (lldb::PathType path_type, FileSpec &file_spec); This will fill in "file_spec" with an appropriate path that is appropriate for the current Host OS. MacOSX will return paths within the LLDB.framework, and other unixes will return the paths they want. The current PathType enums are: typedef enum PathType { ePathTypeLLDBShlibDir, // The directory where the lldb.so (unix) or LLDB mach-o file in LLDB.framework (MacOSX) exists ePathTypeSupportExecutableDir, // Find LLDB support executable directory (debugserver, etc) ePathTypeHeaderDir, // Find LLDB header file directory ePathTypePythonDir // Find Python modules (PYTHONPATH) directory } PathType; All places that were finding executables are and python paths are now updated to use this Host call. Added another new host call to launch the inferior in a terminal. This ability will be very host specific and doesn't need to be supported on all systems. MacOSX currently will create a new .command file and tell Terminal.app to open the .command file. It also uses the new "darwin-debug" app which is a small app that uses posix to exec (no fork) and stop at the entry point of the program. The GDB remote plug-in is almost able launch a process and attach to it, it currently will spawn the process, but it won't attach to it just yet. This will let LLDB not have to share the terminal with another process and a new terminal window will pop up when you launch. This won't get hooked up until we work out all of the kinks. The new Host function is: static lldb::pid_t Host::LaunchInNewTerminal ( const char **argv, // argv[0] is executable const char **envp, const ArchSpec *arch_spec, bool stop_at_entry, bool disable_aslr); Cleaned up FileSpec::GetPath to not use strncpy() as it was always zero filling the entire path buffer. Fixed an issue with the dynamic checker function where I missed a '$' prefix that should have been added. llvm-svn: 116690

Centralized all disassembly into static functions in source/Core/Disassembler.cpp. Added the ability to read memory from the target's object files when we aren't running, so disassembling works before you run! Cleaned up the API to lldb_private::Target::ReadMemory(). Cleaned up the API to the Disassembler to use actual "lldb_private::Address" objects instead of just an "addr_t". This is nice because the Address objects when resolved carry along their section and module which can get us the object file. This allows Target::ReadMemory to be used when we are not running. Added a new lldb_private::Address dump style: DumpStyleDetailedSymbolContext This will show a full breakdown of what an address points to. To see some sample output, execute a "image lookup --address <addr>". Fixed SymbolContext::DumpStopContext(...) to not require a live process in order to be able to print function and symbol offsets. llvm-svn: 107350

There are now to new "settings set" variables that live in each debugger instance: settings set frame-format <string> settings set thread-format <string> This allows users to control the information that is seen when dumping threads and frames. The default values are set such that they do what they used to do prior to changing over the the user defined formats. This allows users with terminals that can display color to make different items different colors using the escape control codes. A few alias examples that will colorize your thread and frame prompts are: settings set frame-format 'frame #${frame.index}: \033[0;33m${frame.pc}\033[0m{ \033[1;4;36m${module.file.basename}\033[0;36m ${function.name}{${function.pc-offset}}\033[0m}{ \033[0;35mat \033[1;35m${line.file.basename}:${line.number}}\033[0m\n' settings set thread-format 'thread #${thread.index}: \033[1;33mtid\033[0;33m = ${thread.id}\033[0m{, \033[0;33m${frame.pc}\033[0m}{ \033[1;4;36m${module.file.basename}\033[0;36m ${function.name}{${function.pc-offset}}\033[0m}{, \033[1;35mstop reason\033[0;35m = ${thread.stop-reason}\033[0m}{, \033[1;36mname = \033[0;36m${thread.name}\033[0m}{, \033[1;32mqueue = \033[0;32m${thread.queue}}\033[0m\n' A quick web search for "colorize terminal output" should allow you to see what you can do to make your output look like you want it. The "settings set" commands above can of course be added to your ~/.lldbinit file for permanent use. Changed the pure virtual void ExecutionContextScope::Calculate (ExecutionContext&); To: void ExecutionContextScope::CalculateExecutionContext (ExecutionContext&); I did this because this is a class that anything in the execution context heirarchy inherits from and "target->Calculate (exe_ctx)" didn't always tell you what it was really trying to do unless you look at the parameter. llvm-svn: 115485

Add UserSettings to Target class, making Target settings the parent of Process settings; add 'default-arch' as a class-wide setting for Target.

Cleaned up code that wasn't using the Initialize and Terminate paradigm by changing it to use it. There was an extra parameter added to the static accessor global user settings controllers that wasn't needed. A bool was being used as a parameter to the accessor just so it could be used to clean up the global user settings controller which is now fixed by splitting up the initialization into the "static void Class::Initialize()", access into the "static UserSettingsControllerSP & Class::GetSettingsController()", and cleanup into "static void Class::Terminate()". Also added initialize and terminate calls to the logging code to avoid issues when LLDB is shutting down. There were cases after the logging was switched over to use shared pointers where we could crash if the global destructor chain was being run and it causes the log to be destroyed and any any logging occurred. llvm-svn: 119757

There are now to new "settings set" variables that live in each debugger instance: settings set frame-format <string> settings set thread-format <string> This allows users to control the information that is seen when dumping threads and frames. The default values are set such that they do what they used to do prior to changing over the the user defined formats. This allows users with terminals that can display color to make different items different colors using the escape control codes. A few alias examples that will colorize your thread and frame prompts are: settings set frame-format 'frame #${frame.index}: \033[0;33m${frame.pc}\033[0m{ \033[1;4;36m${module.file.basename}\033[0;36m ${function.name}{${function.pc-offset}}\033[0m}{ \033[0;35mat \033[1;35m${line.file.basename}:${line.number}}\033[0m\n' settings set thread-format 'thread #${thread.index}: \033[1;33mtid\033[0;33m = ${thread.id}\033[0m{, \033[0;33m${frame.pc}\033[0m}{ \033[1;4;36m${module.file.basename}\033[0;36m ${function.name}{${function.pc-offset}}\033[0m}{, \033[1;35mstop reason\033[0;35m = ${thread.stop-reason}\033[0m}{, \033[1;36mname = \033[0;36m${thread.name}\033[0m}{, \033[1;32mqueue = \033[0;32m${thread.queue}}\033[0m\n' A quick web search for "colorize terminal output" should allow you to see what you can do to make your output look like you want it. The "settings set" commands above can of course be added to your ~/.lldbinit file for permanent use. Changed the pure virtual void ExecutionContextScope::Calculate (ExecutionContext&); To: void ExecutionContextScope::CalculateExecutionContext (ExecutionContext&); I did this because this is a class that anything in the execution context heirarchy inherits from and "target->Calculate (exe_ctx)" didn't always tell you what it was really trying to do unless you look at the parameter. llvm-svn: 115485

Added a user-settable variable, 'target.expr-prefix', which holds the name of a file whose contents are prefixed to each expression. For example, if the file ~/lldb.prefix.header contains: typedef unsigned short my_type; then you can do this: (lldb) settings set target.expr-prefix '~/lldb.prefix.header' (lldb) expr sizeof(my_type) (unsigned long) $0 = 2 When the variable is changed, the corresponding file is loaded and its contents are fetched into a string that is stored along with the target. This string is then passed to each expression and inserted into it during parsing, like this: typedef unsigned short my_type; void $__lldb_expr(void *$__lldb_arg) { sizeof(my_type); } llvm-svn: 117627

Modified LLDB expressions to not have to JIT and run code just to see variable values or persistent expression variables. Now if an expression consists of a value that is a child of a variable, or of a persistent variable only, we will create a value object for it and make a ValueObjectConstResult from it to freeze the value (for program variables only, not persistent variables) and avoid running JITed code. For everything else we still parse up and JIT code and run it in the inferior. There was also a lot of clean up in the expression code. I made the ClangExpressionVariables be stored in collections of shared pointers instead of in collections of objects. This will help stop a lot of copy constructors on these large objects and also cleans up the code considerably. The persistent clang expression variables were moved over to the Target to ensure they persist across process executions. Added the ability for lldb_private::Target objects to evaluate expressions. We want to evaluate expressions at the target level in case we aren't running yet, or we have just completed running. We still want to be able to access the persistent expression variables between runs, and also evaluate constant expressions. Added extra logging to the dynamic loader plug-in for MacOSX. ModuleList objects can now dump their contents with the UUID, arch and full paths being logged with appropriate prefix values. Thread hardened the Communication class a bit by making the connection auto_ptr member into a shared pointer member and then making a local copy of the shared pointer in each method that uses it to make sure another thread can't nuke the connection object while it is being used by another thread. Added a new file to the lldb/test/load_unload test that causes the test a.out file to link to the libd.dylib file all the time. This will allow us to test using the DYLD_LIBRARY_PATH environment variable after moving libd.dylib somewhere else. llvm-svn: 121745

This string is then passed to each expression and inserted into it during parsing, like this: typedef unsigned short my_type; void $__lldb_expr(void *$__lldb_arg) { sizeof(my_type); } llvm-svn: 117627

Add UserSettings to Target class, making Target settings the parent of Process settings; add 'default-arch' as a class-wide setting for Target. Replace lldb::GetDefaultArchitecture with Target::GetDefaultArchitecture & Target::SetDefaultArchitecture. Add 'use-external-editor' as user setting to Debugger class & update code appropriately. Add Error parameter to methods that get user settings, for easier reporting of bad requests. Fix various other minor related bugs. Fix test cases to work with new changes. llvm-svn: 114352
