* Cleaned up many error codes. For any who is filling in error strings intoGreg Clayton2011-10-261-11/+11
| | | | | | | | | | | | | lldb_private::Error objects the rules are: - short strings that don't start with a capitol letter unless the name is a class or anything else that is always capitolized - no trailing newline character - should be one line if possible Implemented a first pass at adding "--gdb-format" support to anything that accepts format with optional size/count. llvm-svn: 142999

| | | | | | | | | | | | | | | | | Ranges. Add eArgTypeWatchpointID and eArgTypeWatchpointIDRange to the CommandArgumentType enums and modify the signature of CommandObject::AddIDsArgumentData() from: AddIDsArgumentData(CommandArgumentEntry &arg) to: AddIDsArgumentData(CommandArgumentEntry &arg, CommandArgumentType ID, CommandArgumentType IDRange) to accommodate. llvm-svn: 140346
* Converted the lldb_private::Process over to use the intrusiveGreg Clayton2011-09-221-1/+1
| | | | | | | | | | | | | | | | | | | | shared pointers. Changed the ExecutionContext over to use shared pointers for the target, process, thread and frame since these objects can easily go away at any time and any object that was holding onto an ExecutionContext was running the risk of using a bad object. Now that the shared pointers for target, process, thread and frame are just a single pointer (they all use the instrusive shared pointers) the execution context is much safer and still the same size. Made the shared pointers in the the ExecutionContext class protected and made accessors for all of the various ways to get at the pointers, references, and shared pointers. llvm-svn: 140298
* Add a new breakpoint type "break by source regular expression".Jim Ingham2011-09-211-131/+110
| | | | | | | | | Fix the RegularExpression class so it has a real copy constructor. Fix the breakpoint setting with multiple shared libraries so it makes one breakpoint not one per shared library. Add SBFileSpecList, to be used to expose the above to the SB interface (not done yet.) llvm-svn: 140225

* Added the ability to remove orphaned module shared pointers from a ModuleList.Greg Clayton2011-08-111-1/+0
| | | | | | | | | | | | | | This is helping us track down some extra references to ModuleSP objects that are causing things to get kept around for too long. Added a module pointer accessor to target and change a lot of code to use it where it would be more efficient. "taret delete" can now specify "--clean=1" which will cleanup the global module list for any orphaned module in the shared module cache which can save memory and also help track down module reference leaks like we have now. llvm-svn: 137294

| | | | | | | | | | | | | | | | | | | | | 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
* Added a new option to the "source list" command that allows us to see whereGreg Clayton2011-04-191-6/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | line tables specify breakpoints can be set in the source. When dumping the source, the number of breakpoints that can be set on a source line are shown as a prefix: (lldb) source list -f test.c -l1 -c222 -b 1 #include <stdio.h> 2 #include <sys/fcntl.h> 3 #include <unistd.h> 4 int 5 sleep_loop (const int num_secs) [2] 6 { 7 int i; [1] 8 for (i=0; i<num_secs; ++i) 9 { [1] 10 printf("%d of %i - sleep(1);\n", i, num_secs); [1] 11 sleep(1); 12 } 13 return 0; [1] 14 } 15 16 int 17 main (int argc, char const* argv[]) [1] 18 { [1] 19 printf("Process: %i\n\n", getpid()); [1] 20 puts("Press any key to continue..."); getchar(); [1] 21 sleep_loop (20); 22 return 12; [1] 23 } Above we can see there are two breakpoints for line 6 and one breakpoint for lines 8, 10, 11, 14, 18, 19, 20, 21 and 23. All other lines have no line table entries for them. This helps visualize the data provided in the debug information without having to manually dump all line tables. It also includes all inline breakpoint that may result for a given file which can also be very handy to see. llvm-svn: 129747
* Added two new classes for command options:Greg Clayton2011-04-131-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* Moved the execution context that was in the Debugger intoGreg Clayton2011-04-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | the CommandInterpreter where it was always being used. Make sure that Modules can track their object file offsets correctly to allow opening of sub object files (like the "__commpage" on darwin). Modified the Platforms to be able to launch processes. The first part of this move is the platform soon will become the entity that launches your program and when it does, it uses a new ProcessLaunchInfo class which encapsulates all process launching settings. This simplifies the internal APIs needed for launching. I want to slowly phase out process launching from the process classes, so for now we can still launch just as we used to, but eventually the platform is the object that should do the launching. Modified the Host::LaunchProcess in the MacOSX Host.mm to correctly be able to launch processes with all of the new eLaunchFlag settings. Modified any code that was manually launching processes to use the Host::LaunchProcess functions. Fixed an issue where lldb_private::Args had implicitly defined copy constructors that could do the wrong thing. This has now been fixed by adding an appropriate copy constructor and assignment operator. Make sure we don't add empty ModuleSP entries to a module list. Fixed the commpage module creation on MacOSX, but we still need to train the MacOSX dynamic loader to not get rid of it when it doesn't have an entry in the all image infos. Abstracted many more calls from in ProcessGDBRemote down into the GDBRemoteCommunicationClient subclass to make the classes cleaner and more efficient. Fixed the default iOS ARM register context to be correct and also added support for targets that don't support the qThreadStopInfo packet by selecting the current thread (only if needed) and then sending a stop reply packet. Debugserver can now start up with a --unix-socket (-u for short) and can then bind to port zero and send the port it bound to to a listening process on the other end. This allows the GDB remote platform to spawn new GDB server instances (debugserver) to allow platform debugging. llvm-svn: 129351
* Modified the ArchSpec to take an optional "Platform *" when setting the triple.Greg Clayton2011-04-071-12/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | 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
* Many improvements to the Platform base class and subclasses. The base PlatformGreg Clayton2011-03-301-8/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | class now implements the Host functionality for a lot of things that make sense by default so that subclasses can check: int PlatformSubclass::Foo () { if (IsHost()) return Platform::Foo (); // Let the platform base class do the host specific stuff // Platform subclass specific code... int result = ... return result; } Added new functions to the platform: virtual const char *Platform::GetUserName (uint32_t uid); virtual const char *Platform::GetGroupName (uint32_t gid); The user and group names are cached locally so that remote platforms can avoid sending packets multiple times to resolve this information. Added the parent process ID to the ProcessInfo class. Added a new ProcessInfoMatch class which helps us to match processes up and changed the Host layer over to using this new class. The new class allows us to search for processs: 1 - by name (equal to, starts with, ends with, contains, and regex) 2 - by pid 3 - And further check for parent pid == value, uid == value, gid == value, euid == value, egid == value, arch == value, parent == value. This is all hookup up to the "platform process list" command which required adding dumping routines to dump process information. If the Host class implements the process lookup routines, you can now lists processes on your local machine: machine1.foo.com % lldb (lldb) platform process list PID PARENT USER GROUP EFF USER EFF GROUP TRIPLE NAME ====== ====== ========== ========== ========== ========== ======================== ============================ 99538 1 username usergroup username usergroup x86_64-apple-darwin FileMerge 94943 1 username usergroup username usergroup x86_64-apple-darwin mdworker 94852 244 username usergroup username usergroup x86_64-apple-darwin Safari 94727 244 username usergroup username usergroup x86_64-apple-darwin Xcode 92742 92710 username usergroup username usergroup i386-apple-darwin debugserver This of course also works remotely with the lldb-platform: machine1.foo.com % lldb-platform --listen 1234 machine2.foo.com % lldb (lldb) platform create remote-macosx Platform: remote-macosx Connected: no (lldb) platform connect connect://localhost:1444 Platform: remote-macosx Triple: x86_64-apple-darwin OS Version: 10.6.7 (10J869) Kernel: Darwin Kernel Version 10.7.0: Sat Jan 29 15:17:16 PST 2011; root:xnu-1504.9.37~1/RELEASE_I386 Hostname: machine1.foo.com Connected: yes (lldb) platform process list PID PARENT USER GROUP EFF USER EFF GROUP TRIPLE NAME ====== ====== ========== ========== ========== ========== ======================== ============================ 99556 244 username usergroup username usergroup x86_64-apple-darwin trustevaluation 99548 65539 username usergroup username usergroup x86_64-apple-darwin lldb 99538 1 username usergroup username usergroup x86_64-apple-darwin FileMerge 94943 1 username usergroup username usergroup x86_64-apple-darwin mdworker 94852 244 username usergroup username usergroup x86_64-apple-darwin Safari The lldb-platform implements everything with the Host:: layer, so this should "just work" for linux. I will probably be adding more stuff to the Host layer for launching processes and attaching to processes so that this support should eventually just work as well. Modified the target to be able to be created with an architecture that differs from the main executable. This is needed for iOS debugging since we can have an "armv6" binary which can run on an "armv7" machine, so we want to be able to do: % lldb (lldb) platform create remote-ios (lldb) file --arch armv7 a.out Where "a.out" is an armv6 executable. The platform then can correctly decide to open all "armv7" images for all dependent shared libraries. Modified the disassembly to show the current PC value. Example output: (lldb) disassemble --frame a.out`main: 0x1eb7: pushl %ebp 0x1eb8: movl %esp, %ebp 0x1eba: pushl %ebx 0x1ebb: subl $20, %esp 0x1ebe: calll 0x1ec3 ; main + 12 at test.c:18 0x1ec3: popl %ebx -> 0x1ec4: calll 0x1f12 ; getpid 0x1ec9: movl %eax, 4(%esp) 0x1ecd: leal 199(%ebx), %eax 0x1ed3: movl %eax, (%esp) 0x1ed6: calll 0x1f18 ; printf 0x1edb: leal 213(%ebx), %eax 0x1ee1: movl %eax, (%esp) 0x1ee4: calll 0x1f1e ; puts 0x1ee9: calll 0x1f0c ; getchar 0x1eee: movl $20, (%esp) 0x1ef5: calll 0x1e6a ; sleep_loop at test.c:6 0x1efa: movl $12, %eax 0x1eff: addl $20, %esp 0x1f02: popl %ebx 0x1f03: leave 0x1f04: ret This can be handy when dealing with the new --line options that was recently added: (lldb) disassemble --line a.out`main + 13 at test.c:19 18 { -> 19 printf("Process: %i\n\n", getpid()); 20 puts("Press any key to continue..."); getchar(); -> 0x1ec4: calll 0x1f12 ; getpid 0x1ec9: movl %eax, 4(%esp) 0x1ecd: leal 199(%ebx), %eax 0x1ed3: movl %eax, (%esp) 0x1ed6: calll 0x1f18 ; printf Modified the ModuleList to have a lookup based solely on a UUID. Since the UUID is typically the MD5 checksum of a binary image, there is no need to give the path and architecture when searching for a pre-existing image in an image list. Now that we support remote debugging a bit better, our lldb_private::Module needs to be able to track what the original path for file was as the platform knows it, as well as where the file is locally. The module has the two following functions to retrieve both paths: const FileSpec &Module::GetFileSpec () const; const FileSpec &Module::GetPlatformFileSpec () const; llvm-svn: 128563
* Added the ability to get the min and max instruction byte size for Greg Clayton2011-03-261-13/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | an architecture into ArchSpec: uint32_t ArchSpec::GetMinimumOpcodeByteSize() const; uint32_t ArchSpec::GetMaximumOpcodeByteSize() const; Added an AddressClass to the Instruction class in Disassembler.h. This allows decoded instructions to know know if they are code, code with alternate ISA (thumb), or even data which can be mixed into code. The instruction does have an address, but it is a good idea to cache this value so we don't have to look it up more than once. Fixed an issue in Opcode::SetOpcodeBytes() where the length wasn't getting set. Changed: bool SymbolContextList::AppendIfUnique (const SymbolContext& sc); To: bool SymbolContextList::AppendIfUnique (const SymbolContext& sc, bool merge_symbol_into_function); This function was typically being used when looking up functions and symbols. Now if you lookup a function, then find the symbol, they can be merged into the same symbol context and not cause multiple symbol contexts to appear in a symbol context list that describes the same function. Fixed the SymbolContext not equal operator which was causing mixed mode disassembly to not work ("disassembler --mixed --name main"). Modified the disassembler classes to know about the fact we know, for a given architecture, what the min and max opcode byte sizes are. The InstructionList class was modified to return the max opcode byte size for all of the instructions in its list. These two fixes means when disassemble a list of instructions and dump them and show the opcode bytes, we can format the output more intelligently when showing opcode bytes. This affects any architectures that have varying opcode byte sizes (x86_64 and i386). Knowing the max opcode byte size also helps us to be able to disassemble N instructions without having to re-read data if we didn't read enough bytes. Added the ability to set the architecture for the disassemble command. This means you can easily cross disassemble data for any supported architecture. I also added the ability to specify "thumb" as an architecture so that we can force disassembly into thumb mode when needed. In GDB this was done using a hack of specifying an odd address when disassembling. I don't want to repeat this hack in LLDB, so the auto detection between ARM and thumb is failing, just specify thumb when disassembling: (lldb) disassemble --arch thumb --name main You can also have data in say an x86_64 file executable and disassemble data as any other supported architecture: % lldb a.out Current executable set to 'a.out' (x86_64). (lldb) b main (lldb) run (lldb) disassemble --arch thumb --count 2 --start-address 0x0000000100001080 --bytes 0x100001080: 0xb580 push {r7, lr} 0x100001082: 0xaf00 add r7, sp, #0 Fixed Target::ReadMemory(...) to be able to deal with Address argument object that isn't section offset. When an address object was supplied that was out on the heap or stack, target read memory would fail. Disassembly uses Target::ReadMemory(...), and the example above where we disassembler thumb opcodes in an x86 binary was failing do to this bug. llvm-svn: 128347
* Fixed the LLDB build so that we can have private types, private enums andGreg Clayton2011-03-241-8/+8

* Check in an initial implementation of the "breakpoint clear" command, whose ↵Johnny Chen2010-10-281-4/+193
| | | | | | | | | | | | | | | | | | | | purpose is clear the breakpoint associated with the (filename, line_number) combo when an arrow is pointing to a source position using Emacs Grand Unified Debugger library to interact with lldb. The current implmentation is insufficient in that it only asks the breakpoint whether it is associated with a breakpoint resolver with FileLine type and whether it matches the (filename, line_number) combo. There are other breakpoint resolver types whose breakpoint locations can potentially match the (filename, line_number) combo. The BreakpointResolver, BreakpointResolverName, BreakpointResolverAddress, and BreakpointResolverFileLine classes have extra static classof methods to support LLVM style type inquiry through isa, cast, and dyn_cast. The Breakpoint class has an API method bool GetMatchingFileLine(...) which is invoked from CommandObjectBreak.cpp to implement the "breakpoint clear" command. llvm-svn: 117562

* Fixed an issue where we were resolving paths when we should have been.Greg Clayton2010-10-201-8/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | So the issue here was that we have lldb_private::FileSpec that by default was always resolving a path when using the: FileSpec::FileSpec (const char *path); and in the: void FileSpec::SetFile(const char *pathname, bool resolve = true); This isn't what we want in many many cases. One example is you have "/tmp" on your file system which is really "/private/tmp". You compile code in that directory and end up with debug info that mentions "/tmp/file.c". Then you type: (lldb) breakpoint set --file file.c --line 5 If your current working directory is "/tmp", then "file.c" would be turned into "/private/tmp/file.c" which won't match anything in the debug info. Also, it should have been just a FileSpec with no directory and a filename of "file.c" which could (and should) potentially match any instances of "file.c" in the debug info. So I removed the constructor that just takes a path: FileSpec::FileSpec (const char *path); // REMOVED You must now use the other constructor that has a "bool resolve" parameter that you must always supply: FileSpec::FileSpec (const char *path, bool resolve); I also removed the default parameter to SetFile(): void FileSpec::SetFile(const char *pathname, bool resolve); And fixed all of the code to use the right settings. llvm-svn: 116944
* Added support for breakpoint conditions. I also had to separate the "run ↵Jim Ingham2010-10-141-18/+43
| | | | | | | | the expression" part of ClangFunction::Execute from the "Gather the expression result" so that in the case of the Breakpoint condition I can move the condition evaluation into the normal thread plan processing. Also added support for remembering the "last set breakpoint" so that "break modify" will act on the last set breakpoint. llvm-svn: 116542
* Modified the "breakpoint set --name NAME" to be the auto breakpoint set Greg Clayton2010-10-121-13/+12
| | | | | | | | | | | | | | | | | | | | | | | | | function. It will inspect NAME and do the following: - if the name contains '(' or starts with "-[" or "+[" then a full name search will happen to match full function names with args (C++ demangled names) or full objective C method prototypes. - if the name contains "::" and no '(', then it is assumed to be a qualified function name that is in a namespace or class. For "foo::bar::baz" we will search for any functions with the basename or method name of "baz", then filter the results to only those that contain "foo::bar::baz". This allows setting breakpoint on C++ functions and methods without having to fully qualify all of the types that would appear in C++ mangled names. - if the name contains ":" (not "::"), then NAME is assumed to be an ObjC selector. _ otherwise, we assume just a plain function basename. Now that "--name" is our "auto" mode, I introduced the new "--basename" option ("breakpoint set --basename NAME") to allow for function names that aren't methods or selectors, just basenames. This can also be used to ignore C++ namespaces and class hierarchies for class methods. Fixed clang enumeration promotion types to be correct. llvm-svn: 116293
* Added a "--no-lldbinit" option (-n for short (which magically matchesGreg Clayton2010-10-111-57/+58

* Add infrastructure for standardizing arguments for commands andCaroline Tice2010-10-011-17/+95
| | | | | | | | | | | | | | | | | | | | | | | | | | | command options; makes it easier to ensure that the same type of argument will have the same name everywhere, hooks up help for command arguments, so that users can ask for help when they are confused about what an argument should be; puts in the beginnings of the ability to do tab-completion for certain types of arguments, allows automatic syntax help generation for commands with arguments, and adds command arguments into command options help correctly. Currently only the breakpoint-id and breakpoint-id-range arguments, in the breakpoint commands, have been hooked up to use the new mechanism. The next steps will be to fix the command options arguments to use this mechanism, and to fix the rest of the regular command arguments to use this mechanism. Most of the help text is currently missing or dummy text; this will need to be filled in, and the existing argument help text will need to be cleaned up a bit (it was thrown in quickly, mostly for testing purposes). Help command now works for all argument types, although the help may not be very helpful yet. Those commands that take "raw" command strings now indicate it in their help text. llvm-svn: 115318
* Fix breakpoint id range testing to disallow ranges that specify breakpoint ↵Caroline Tice2010-09-291-6/+6
| | | | | | | | | | | | | | locations from crossing major breakpoint boundaries (must be within a single breakpoint if specifying locations). Add .* as a means of specifying all the breakpoint locations under a major breakpoint, e.g. "3.*" means "all the breakpoint locations of breakpoint 3". Fix error message to make more sense, if user attempts to specify a breakpoint command when there isn't a target yet. llvm-svn: 115077
* General command line help cleanup:Greg Clayton2010-09-181-32/+17
| | | | | | | | | | - All single character options will now be printed together - Changed all options that contains underscores to contain '-' instead - Made the help come out a little flatter by showing the long and short option on the same line. - Modified the short character for "--ignore-count" options to "-i" llvm-svn: 114265
* Fixed the way set/show variables were being accessed to being natively Greg Clayton2010-09-181-45/+48
| | | | | | | | | | | | | | | | | | 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

* Change the "-S", "-F" and "-M" options to take their arguments directly, ↵Jim Ingham2010-08-261-15/+13
| | | | | | rather than requiring the -n option. This means you can't "or" together the types (i.e. set a breakpoint on a method or selector called "whatever". But that is a pretty uncommon operation, and having to provide two flags for the more common "set a breakpoint on this selector" is annoying. llvm-svn: 112245
* Change "Current" as in GetCurrentThread, GetCurrentStackFrame, etc, to ↵Jim Ingham2010-08-261-6/+6
| | | | | | "Selected" i.e. GetSelectedThread. Selected makes more sense, since these are set by some user action (a selection). I didn't change "CurrentProcess" since this is always controlled by the target, and a given target can only have one process, so it really can't be selected. llvm-svn: 112221

* Added function name types to allow us to set breakpoints by name moreGreg Clayton2010-06-281-34/+81
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Added a GetDescription method to many of the SymbolContext objects for the more verbose output. llvm-svn: 107075
* Very large changes that were needed in order to allow multiple connectionsGreg Clayton2010-06-231-30/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
