If you "command script import" this file, then you will have two new commands:
(lldb) tk-variables
(lldb) tk-process
Not sure how this will work on all other systems, but on MacOSX, you will get a window with a tree view that allows you to inspect your local variables by expanding variables to see the child values.
The "tk-process" allows you to inspect the currently selected process by expanding the process to see the threads, the threads to see the frames, and the frames to see the variables. Very handy if you want to view variables for all frames simultaneously.

forward declarations!", but it no longer fails when built with
Clang 3.4.1 (system compiler) or 3.5 from SVN on FreeBSD.

requirement for a command instead of the smallest. e.g. if a command
requires a Target, Process, Thread, and Frame, and none of those
are available, report the largest -- Target -- as being missing
instead of the smallest -- Frame.

platform locations. We didn't always do an exhaustive search through all the
platform locations, so we would have to read some files out of memory even though
they existed in the exploded shared cache or SDK.

that would clear the module list, and then put it back by hand. But we forgot to
also put its sections back in the target SectionList, so we would jettison it as
unloaded when we finished handling the first real load event. Add its sections.

Changes include:
- fix it so you can select the "host" platform using "platform select host"
- change all callbacks that create platforms to returns shared pointers
- fix TestImageListMultiArchitecture.py to restore the "host" platform by running "platform select host"
- Add a new "PlatformSP Platform::Find(const ConstString &name)" method to get a cached platform
- cache platforms that are created and re-use them instead of always creating a new one

For the Objective-C case, we do not have a "function type" notion, so we actually end up wrapping the clang ObjCMethodDecl in the Impl object, and ask function-y questions of it
In general, you can always ask for return type, number of arguments, and type of each argument using the TypeMemberFunction layer - but in the C++ case, you can also acquire a Type object for the function itself, which instead you can't do in the Objective-C case

The $A handler was unnecessarily waiting for the launched app to hit a stop
before returning. Removed this code.
Renamed the llgs inferior launching code to LaunchProcessForDebugging ()
to prevent it from possibly being mistaken as code that lldb-platform uses
to launch a debugserver process. We probably want to look at breaking out
llgs-specific and lldb-platform-specific code into separate derived classes,
with common code in a shared base class.

The issue was GDBRemoteCommunication::CheckForPacket() already fixes up any prefixed bytes (0x7d followed by value that is XOR'ed with 0x20). If we do this again, we cause binary packets to lose bytes.
This allows lldb-platform to be able to upload binaries and debug them remotely.

% lldb ios-executable
(lldb) platform connect connect://localhost:11111
Prior to this fix, the host platform would be selected even though the target was using the ios-remote platform.

The problem was the read_func we were supplying to the interactive interpreter wasn't stripping the newline from the end of the string. Now it does and multi-line python scripts can be typed in Xcode.

This allows us to fixup the address of the symbol as soon as we parse it
so that lldb is not confused thinking there are two different symbols in
the binary (one with the thumb bit, one without). Also, differentiating
between THUMB and ARM symbols allows the debugger to place the right
type of breakpoint.

There are several places where multiple threads are accessing the same variables simultaneously without any kind of protection. I propose using std::atomic<> to make it safer. I did a special build of lldb, using the google tool 'thread sanitizer' which identified many cases of multiple threads accessing the same memory. std::atomic is low overhead and does not use any locks for simple types such as int/bool.

There are target pointer members in struct jit_code_entry and jit_descriptor.
Data layout of those structures should be decided by target, not host.
This fixes JITLoaderGDB for 64-bit host and 32-bit target.

Also, in case they don't define any, change the default from "Run Python function <blah>" into "For more information run help <blah>"
The core issue here is that Python only allows one docstring per function, so we can't really attach both a short and a long help to the same command easily
There are alternatives but this is not a pressing enough concern to go through the motions quite yet

ELF objects contain marker symbols to differentiate between ARM and
THUMB functions. Instead of storing them internally and having garbage
show up when symbols are searched for by the user, we can just skip them
and not store them at all, as we never actually need them.

Instead of forcing the remote arch type to MachO all the time, we
inspect the OS/vendor that the remote debug server reports and use it to
set the arch type to MachO, ELF or COFF accordingly.

This is useful for checking inconsistencies between what the remote debug server thinks we are debugging and we think we are debugging. This follows the check for pointer byte size done just above.

* Fixes the local stack variable return pointer usage in NativeThreadLinux::GetName().
* Changes NativeThreadProtocol::GetName() to return a std::string.
* Adds a unit test to verify thread names don't regress in the future. Currently only run on Linux since I know default thread names there.

Apparently, PEEKUSER/POKEUSER is something x86 specific, so I had to rework it for AArch64. This fixes assertion that occurs whenever lldb started on AArch64 device tried to read PC register (or any other register)
