represent pointers and arrays by adding an extra parameter to the 

SBValue
SBValue::GetChildAtIndex (uint32_t idx, 
                         DynamicValueType use_dynamic, 
                         bool can_create_synthetic);

The new "can_create_synthetic" will allow you to create child values that
aren't actually a part of the original type. So if you code like:

int *foo_ptr = ...

And you have a SBValue that contains the value for "foo_ptr":

SBValue foo_value = ...

You can now get the "foo_ptr[12]" item by doing this:

v = foo_value.GetChiltAtIndex (12, lldb.eNoDynamicValues, True);

Normall the "foo_value" would only have one child value (an integer), but
we can create "synthetic" child values by treating the pointer as an array.

Likewise if you have code like:

int array[2];

array_value = ....

v = array_value.GetChiltAtIndex (0);     // Success, v will be valid
v = array_value.GetChiltAtIndex (1);     // Success, v will be valid
v = array_value.GetChiltAtIndex (2);     // Fail, v won't be valid, "2" is not a valid zero based index in "array"

But if you use the ability to create synthetic children:

v = array_value.GetChiltAtIndex (0, lldb.eNoDynamicValues, True);     // Success, v will be valid
v = array_value.GetChiltAtIndex (1, lldb.eNoDynamicValues, True);     // Success, v will be valid
v = array_value.GetChiltAtIndex (2, lldb.eNoDynamicValues, True);     // Success, v will be valid

same as the old "connect://<host>:<port>". Also added the ability to
connect using "udp://<host>:<port>" which will open a connected 
datagram socket. I need to find a way to specify a non connected
datagram socket as well. 

We might need to start setting some settings in the URL itself, 
maybe something like:

udp://<host>:<port>?connected=yes
udp://<host>:<port>?connected=no

I am open to suggestions for URL settings.

Also did more work on the KDP darwin kernel plug-in.

 - you can use a Python script to write a summary string for data-types, in one of
   three ways:
    -P option and typing the script a line at a time
    -s option and passing a one-line Python script
    -F option and passing the name of a Python function
   these options all work for the "type summary add" command
   your Python code (if provided through -P or -s) is wrapped in a function
   that accepts two parameters: valobj (a ValueObject) and dict (an LLDB
   internal dictionary object). if you use -F and give a function name,
   you're expected to define the function on your own and with the right
   prototype. your function, however defined, must return a Python string
 - test case for the Python summary feature
 - a few quirks:
  Python summaries cannot have names, and cannot use regex as type names
  both issues will be fixed ASAP
major redesign of type summary code:
 - type summary working with strings and type summary working with Python code
   are two classes, with a common base class SummaryFormat
 - SummaryFormat classes now are able to actively format objects rather than
   just aggregating data
 - cleaner code to print descriptions for summaries
the public API now exports a method to easily navigate a ValueObject hierarchy
New InputReaderEZ and PriorityPointerPair classes
Several minor fixes and improvements

The reasom of the crash is because of a missing entry in the argument table corresponding to eArgTypeUnsignedInteger.
Add such entry and modify the call site of the crash to go through a fail-fast API to retrieve the argument table.

to 'char argv' and 'char envp' by morphing them into the 'list argv' and 'list envp' (as a list of
Python strings).

 - formats %s %char[] %c and %a now work to print 0-terminated c-strings if they are applied to a char* or char[] even without the [] operator (e.g. ${var%s})
 - array formats (char[], intN[], ..) now work when applied to an array of a scalar type even without the [] operator (e.g. ${var%int32_t[]})
LLDB will not crash because of endless loop when trying to obtain a summary for an object that has no value and references itself in its summary string
In many cases, a wrong summary string will now display an "<error>" message instead of giving out an empty string

by name by adding an extra parameter to the lldb_private::Target breakpoint 
setting functions.

Added a function in the DWARF symbol file plug-in that can dump errors
and prints out which DWARF file the error is happening in so we can track
down what used to be assertions easily.

Fixed the MacOSX kernel plug-in to properly read the kext images and set
the kext breakpoint to watch for kexts as they are loaded.

Also made:
(lldb) !<NUM>
(lldb) !-<NUM>
(lldb) !!

work with the history.  For added benefit:

(lldb) !<NUM><TAB>

will insert the command at position <NUM> in the history into the command line to be edited.

This is only partial, I still need to sync up editline's history list with the one kept by the interpreter.

 - a new --name option for "type summary add" lets you give a name to a summary
 - a new --summary option for "frame variable" lets you bind a named summary to one or more variables
${var%s} now works for printing the value of 0-terminated CStrings
type format test case now tests for cascading

Passing in os.ctermid() as the arg for SBTarget.Launch(...) for stdin_path, stdout_path, and stderr_path
is just wrong and resulted in the inferior's output getting mixed into the GDB remote communication's
log file.  Change all test cases to not pass os.ctermid() and either use SBTarget.LaunchSimple() or
SBTarget.Launch() and pass None as stdin_path/stdout_path/srderr_path to use a pseudo terminal.

before issuing API calls to find the global variable and to get its value.

rdar://problem/9700873 has been updated to reflect the latest status.  The dwarf case
now does not seg fault if the inferior is not started; instead, for dwarf case, the

with the "target modules lookup --address <addr>" command. The variable
ID's, names, types, location for the address, and declaration is
displayed.

This can really help with crash logs since we get, on MacOSX at least,
the registers for the thread that crashed so it is often possible to
figure out some of the variable contents.

use lldb_private::Target::ReadMemory(...) to allow constant strings
to be displayed in global variables prior on in between process
execution.

Centralized the variable declaration dumping into:

	bool
	Variable::DumpDeclaration (Stream *s, bool show_fullpaths, bool show_module);

Fixed an issue if you used "target variable --regex <regex>" where the
variable name would not be displayed, but the regular expression would.

Fixed an issue when viewing global variables through "target variable"
might not display correctly when doing DWARF in object files.

Made it so that you can create synthetic children of array
value objects. This is for creating array members when the
array index is out of range. This comes in handy when you have
a structure definition like:

struct Collection
{
    uint32_t count;
    Item array[0];
};
"array" has 1 item, but many times in practice there are more
items in "item_array".

This allows you to do:

(lldb) target variable g_collection.array[3]

To implement this, the get child at index has been modified
to have a "ignore_array_bounds" boolean that can be set to true.
