      Moved the execution context that was in the Debugger into · 8b82f087
      Greg Clayton authored
      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.

      Modified the ArchSpec to take an optional "Platform *" when setting the triple. · eb0103f2
      Greg Clayton authored
      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.

      Many improvements to the Platform base class and subclasses. The base Platform · 32e0a750
      Greg Clayton authored
      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

      This of course also works remotely with the lldb-platform:

      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;

      Split all of the core of LLDB.framework/lldb.so into a · 7a5388bf
      Greg Clayton authored
      static archive that can be linked against. LLDB.framework/lldb.so
      exports a very controlled API. Splitting the API into a static
      library allows other tools (debugserver for now) to use the power
      of the LLDB debugger core, yet not export it as its API is not
      portable or maintainable. The Host layer and many of the other
      internal only APIs can now be statically linked against.
      
      Now LLDB.framework/lldb.so links against "liblldb-core.a" instead
      of compiling the .o files only for the shared library. This fix
      is only for compiling with Xcode as the Makefile based build already
      does this.
      
      The Xcode projecdt compiler has been changed to LLVM. Anyone using
      Xcode 3 will need to manually change the compiler back to GCC 4.2,
      or update to Xcode 4.

      Don't limit StreamTee to just two streams. It now can contain · 9d0402b1
      Greg Clayton authored
      N streams by making the stream a vector of stream shared pointers
      that is protected by a mutex. Streams can be get/set by index which
      allows indexes to be defined as stream indentifiers. If a stream is
      set at index 3 and there are now streams in the collection, then
      empty stream objects are inserted to ensure that stream at index 3
      has a valid stream. There is also an append method that allows a stream
      to be pushed onto the stack. This will allow our streams to be very
      flexible in where the output goes.
      
      Modified the CommandReturnObject to use the new StreamTee functionality.
      This class now defines two StreamTee indexes: 0 for the stream string
      stream, and 1 for the immediate stream. This is used both on the output
      and error streams.
      
      Added the ability to get argument types as strings or as descriptions.
      This is exported through the SBCommandInterpreter API to allow external
      access.
      
      Modified the Driver class to use the newly exported argument names from
      SBCommandInterpreter::GetArgumentTypeAsCString().

      Added support for attaching to a remote debug server with the new command: · b766a73d
      Greg Clayton authored
      (lldb) process connect <remote-url>
      
      Currently when you specify a file with the file command it helps us to find
      a process plug-in that is suitable for debugging. If you specify a file you
      can rely upon this to find the correct debugger plug-in:
      
      % lldb a.out
      Current executable set to 'a.out' (x86_64).
      (lldb) process connect connect://localhost:2345
      ...
      
      If you don't specify a file, you will need to specify the plug-in name that
      you wish to use:
      
      % lldb
      (lldb) process connect --plugin process.gdb-remote connect://localhost:2345
      
      Other connection URL examples:
      
      (lldb) process connect connect://localhost:2345
      (lldb) process connect tcp://127.0.0.1
      (lldb) process connect file:///dev/ttyS1
      
      We are currently treating the "connect://host:port" as a way to do raw socket
      connections. If there is a URL for this already, please let me know and we
      will adopt it.
      
      So now you can connect to a remote debug server with the ProcessGDBRemote
      plug-in. After connection, it will ask for the pid info using the "qC" packet
      and if it responds with a valid process ID, it will be equivalent to attaching.
      If it response with an error or invalid process ID, the LLDB process will be
      in a new state: eStateConnected. This allows us to then download a program or
      specify the program to run (using the 'A' packet), or specify a process to
      attach to (using the "vAttach" packets), or query info about the processes
      that might be available.

      Add infrastructure for standardizing arguments for commands and
      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.

      accessed by the objects that own the settings. The previous approach wasn't

      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").

      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.
