1. Using mach port number, just like when inferior is paused.
2. Use key:value pair of thread used time instead of comma separated notation.

Adding useful formatting options to the expression (expr) command.
As a side effect of this change, the -d option now supports the same three-values enumeration that frame variables uses (run, don't run, none) instead of a boolean like it did previously

These options do not apply to print, p or po because these are aliased to not take any options.
In order to use them, use expression or expr.

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.

Add a "--reverse" or "-r" option to the "list" with no options command.  This will list backwards from the
last source point listed.
Also fix the setting of the default file & line to the file containing main, when you do a plain "list".

<rdar://problem/12685226>

llvm-svn: 171945

Updated documentation on the "register_data_addr" key that can be supplied in the "thread" dictionary return value for the python OS plug-ins.

Add an SBProcess API to get the current StopID, either considering or ignoring stops caused by expression
evaluation.

Checking in the support for doing index ids reservation when given a thread id.

llvm-svn: 171904

Python OS plug-ins now fetch thread registers lazily.

Also changed SBCommandInterpreter::HandleCommand() to not take the API lock. The logic here is that from the command line you can execute a command that might result in another thread (like the private process thread) to execute python or run any code that can re-enter the public API. When this happens, a deadlock immediately occurs for things like "process launch" and "process attach".

Fix TestSendSignals.py on Linux. The wrong stop reason was being set when stopping for a received signal.

llvm-svn: 171819

Setting breakpoints using "breakpoint set --selector <SEL>" previously didn't when there was no dSYM file.

Also fixed issues in the test suite that arose after fixing the bug.

Also fixed the log channels to properly ref count the log streams using weak pointers to the streams. This fixes a test suite problem that would happen when you specified a full path to the compiler with the "--compiler" option.

- bug fixed in r170241, thanks Andy!
- closing related PR 14423

llvm-svn: 171794

Add unconditional logging messages to every place in debugserver
where we send a SIGKILL signal or do a ptrace PT_KILL call to
terminate the inferior process.  When the debuggee is silently
killed off, the console logging from debugserver can disambiguate
whether debugserver killed off the process because it failed to
completely set it up, becuase it was told to (via the "k" packet),
or if some external daemon killed it.

- due to bugzilla 14806 (platform status command prints more information on Mac OS X than on Linux)

Added a page that describes how to to manual symbolication with LLDB from the command line, from python, and also how to use the build in modules to do symbolication.

llvm-svn: 171477

Added SBTarget::EvaluateExpression() so expressions can be evaluated without needing a process.

Also fixed many functions that deal with clang AST types to be able to properly handle the clang::Type::Elaborated types ("struct foo", "class bar").

Added an SBAPI to get the PythonPath (if the Host knows how to do that).  And a -P option to the Driver

it was told to run.
