17fafa155c Remove the “len” defaulted parameter from CommandReturnObject::AppendMessage, AppendWarning and AppendError. Nobody was using them, and it meant if you accidentally used the AppendWarning when you meant AppendWarningWithFormat with an integer in the format string, it would compile and then return your string plus some unknown amount of junk.

Memory read's "repeat" behavior forgets "-t" option. It also formatted the type as hex bytes + ASCII. Now we revert to the default format when displaying types unless the user sets the format option manually.

bf4b7be68e Removed the == and != operators from ArchSpec, since
equality can be strict or loose and we want code to
explicitly choose one or the other.

Also renamed the Compare function to IsEqualTo, to
avoid confusion.

c627682ef7 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[])

7b8c513f08 Option changes:
the option to print the runtime-specific description has been modified in the frame variable, memory read and expression command.

All three commands now support a --object-description option, with a shortcut of -O (uppercase letter o)

This is a breaking change:
frame variable used --objc as the long option name
expression used -o as a shortcut
memory read uses --objd as the long option name

Hopefully, most users won't be affected by the change since people tend to access "expression --object-description" under the alias "po" which still works

The test suite has been tweaked accordingly.

b9d5df58d4 <rdar://problem/12820334>
I modified the "Args::StringtoAddress(...)" function to be able to evaluate address expressions. This is now used for any command line arguments or options that takes addresses like:

memory read <addr> [<end-addr>]
memory write <addr>
breakpoint set --address <addr>
disassemble --start-address <addr> --end-address <addr>

It calls the expression parser to evaluate the address expression and will also work around the issue where the compiler doesn't like to add offsets to function pointers (which is what happens when you try to evaluate "main + 12"). So there is a temp fix in the Args::StringtoAddress() to work around this until we can get special compiler support for debug expressions with function pointers.

3bcdfc0ec1 <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

1c5f186f30 Added new options to "target create" and "target modules add".
For "target create" you can now specify "--no-dependents" to not track down and add all dependent shared libraries. This can be handy when doing manual symbolication. Also added the "--symfile" or "-s" for short so you can specify a module and a stand alone debug info file:

(lldb) target create --symfile /tmp/a.dSYM /usr/bin/a

Added the "--symfile" option to the "target modules add" for the same reason. These all help with manualy symbolication and expose functionality that was previously only available through the public API layer.

This commit does three things:
(a) introduces a new notification model for adding/removing/changing modules to a ModuleList, and applies it to the Target's ModuleList, so that we make sure to always trigger the right set of actions
whenever modules come and go in a target. Certain spots in the code still need to "manually" notify the Target for several reasons, so this is a work in progress
(b) adds a new capability to the Platforms: locating a scripting resources associated to a module. A scripting resource is a Python file that can load commands, formatters, ... and any other action
of interest corresponding to the loading of a module. At the moment, this is only implemented on Mac OS X and only for files inside .dSYM bundles - the next step is going to be letting
the frameworks themselves hold their scripting resources. Implementors of platforms for other systems are free to implement "the right thing" for their own worlds
(c) hooking up items (a) and (b) so that targets auto-load the scripting resources as the corresponding modules get loaded in a target. This has a few caveats at the moment:
 - the user needs to manually add the .py file to the dSYM (soon, it will also work in the framework itself)
 - if two modules with the same name show up during the lifetime of an LLDB session, the second one won't be able to load its scripting resource, but will otherwise work just fine

d073fe4e5b When we were calculating the max byte size of ONE instruction to handle something like
x/9i

we actually calculated the size of 9 instructions.  Then we multiplied it by the count again 
to get the total amount we should fetch, so we thought 9 x86_64 instructions took over 1K
to fetch...

3154255fd6 This is a fix for the command option parser.
There was a generic catch-all type for path arguments
called "eArgTypePath," and a specialized version
called "eArgTypeFilename."  It turns out all the
cases where we used eArgTypePath we could have
used Filename or we explicitly meant a directory.

I changed Path to DirectoryName, made it use the
directory completer, and rationalized the uses of
Path.

<rdar://problem/12068650>

More fixes to how we handle paths that are used to create a target.

This modification centralizes the location where and how what the user specifies gets resolved. Prior to this fix, the TargetList::CreateTarget variants took a FileSpec object which meant everyone had the opportunity to resolve the path their own way. Now both CreateTarget variants take a "const char *use_exe_path" which allows the TargetList::CreateTarget to centralize where the resolving happens and "do the right thing".

453925530d <rdar://problem/12462048>
LLDB changes argv[0] when debugging a symlink. Now we have the notion of argv0 in the target settings:

target.arg0 (string) = 

There is also the program argument that are separate from the first argument that have existed for a while:

target.run-args (arguments) =

When running "target create <exe>", we will place the untouched "<exe>" into target.arg0 to ensure when we run, we run with what the user typed. This has been added to the ProcessLaunchInfo and all other needed places so we always carry around the:
- resolved executable path
- argv0
- program args

Some systems may not support separating argv0 from the resolved executable path and the ProcessLaunchInfo needs to carry all of this information along so that each platform can make that decision.

virtual CommandObject *
GetPluginCommandObject();

This object returned should be a multi-word command that vends LLDB commands. There is a sample implementation in ProcessGDBRemote that is hollowed out. It is intended to be used for sending a custom packet, though the body of the command execute function has yet to be implemented!

4f465cff8a Change the Thread constructor over to take a Process& rather than a ProcessSP. We can't create Threads with a NULL ProcessSP, so it makes no sense to use the SP.
Then make the Thread a Broadcaster, and get it to broadcast when the selected frame is changed (but only from the Command Line) and when Thread::ReturnFromFrame 
changes the stack.
Made the Driver use this notification to print the new thread status rather than doing it in the command.
Fixed a few places where people were setting their broadcaster class by hand rather than using the static broadcaster class call.

ccd41e55f1 Ran the sources through the compiler with -Wshadow warnings
enabled after we'd found a few bugs that were caused by shadowed
local variables; the most important issue this turned up was
a common mistake of trying to obtain a mutex lock for the scope
of a code block by doing

        Mutex::Locker(m_map_mutex);

This doesn't assign the lock object to a local variable; it is
a temporary that has its dtor called immediately.  Instead,

        Mutex::Locker locker(m_map_mutex);

does what is intended.  For some reason -Wshadow happened to
highlight these as shadowed variables.

I also fixed a few obivous and easy shadowed variable issues
across the code base but there are a couple dozen more that
should be fixed when someone has a free minute.

4bd4e7e3ba Add support for debugging KASLR kernels via kdp (the kernel being
loaded at a random offset).

To get the kernel's UUID and load address I need to send a kdp
packet so I had to implement the kernel relocation (and attempt to
find the kernel if none was provided to lldb already) in ProcessKDP
-- but this code really properly belongs in DynamicLoaderDarwinKernel.

I also had to add an optional Stream to ConnectRemote so
ProcessKDP::DoConnectRemote can print feedback about the remote kernel's
UUID, load address, and notify the user if we auto-loaded the kernel via
the UUID.

21dfcd9d41 Implementing plugins that provide commands.
This checkin adds the capability for LLDB to load plugins from external dylibs that can provide new commands
It exports an SBCommand class from the public API layer, and a new SBCommandPluginInterface

There is a minimal load-only plugin manager built into the debugger, which can be accessed via Debugger::LoadPlugin.

Plugins are loaded from two locations at debugger startup (LLDB.framework/Resources/PlugIns and ~/Library/Application Support/LLDB/PlugIns) and more can be (re)loaded via the "plugin load" command

For an example of how to make a plugin, refer to the fooplugin.cpp file in examples/plugins/commands

Caveats:
	Currently, the new API objects and features are not exposed via Python.
	The new commands can only be "parsed" (i.e. not raw) and get their command line via a char** parameter (we do not expose our internal Args object)
	There is no unloading feature, which can potentially lead to leaks if you overwrite the commands by reloading the same or different plugins
	There is no API exposed for option parsing, which means you may need to use getopt or roll-your-own
