to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Summary:
The Debuffer object was being used in "GetListenerForProcess" to provide
a default listener object if one was not specified in the launch_info
object.
Since all the callers of this function immediately passed the result to
Target::CreateProcess, it was easy to move this logic there instead.
This brings us one step closer towards being able to move the LaunchInfo
classes to the Host layer (which is there the launching code that
consumes them lives).

This patch moves the EnumerateDirectory functionality and related enum

This is part of a set of patches that extracts file system related

the VFS into LLDB this change is sufficient.

This patch extends the FileSystem class with a bunch of functions that
are currently implemented as methods of the FileSpec class. These
methods will be removed in future commits and replaced by calls to the
file system.
The new functions are operated in terms of the virtual file system which
was recently moved from clang into LLVM so it could be reused in lldb.
Because the VFS is stateful, we turned the FileSystem class into a
singleton.

This fixes a bug PlatformDarwin::SDKSupportsModule introduced by

with an optional third (micro) component, but the parse will fail when
there are extra characters after the version number (e.g.: trying to

after that patch). Fixed here by stripping the ".sdk" suffix first.

This is an NFC commit to refactor the "load dependent files" parameter
from a boolean to an enum value. We want to be able to specify a
default, in which case we decide whether or not to load the dependent
files based on whether the target is an executable or not (i.e. a
dylib).
This is a dependency for D51934.

Summary:
D48465 is currently blocked by the fact that tab-completing the first expression is deadlocking LLDB.
The reason for this deadlock is that when we push the ProcessIO handler for reading the Objective-C runtime
information from the executable (which is triggered when we parse the an expression for the first time),
the IOHandler can't be pushed as the Editline::Cancel method is deadlocking.
The deadlock in Editline is coming from the m_output_mutex, which is locked before we go into tab completion.
Even without this lock, calling Cancel on Editline will mean that Editline cleans up behind itself and deletes the
current user-input, which is screws up the console when we are tab-completing at the same time.
I think for now the most reasonable way of fixing this is to just not call Cancel on the current IOHandler when we push
the IOHandler for running an internal utility function.
As we can't really write unit tests for IOHandler itself (due to the hard dependency on an initialized Debugger including
all its global state) and Editline completion is currently also not really testable in an automatic fashion, the test for this has
to be that the expression command completion in D48465 doesn't fail when requesting completion the first time.
A more precise test plan for this is:
1. Apply D48465.
2. Start lldb and break in some function.
3. Type `expr foo` and press tab to request completion.
4. Without this patch, we deadlock and LLDB stops responding.
I'll provide an actual unit test for this once I got around and made the IOHandler code testable,
but for now unblocking D48465 is more critical.
Thanks to Jim for helping me debugging this.

Summary:
LLDB_PLUGINS doesn't exist as a variable, so this line doesn't add any dependencies and is

The gdb-remote CMake itself is using a local LLDB_PLUGINS variable, so that code is fine.

Summary:
Instead of a function taking an enum value determining which path to
return, we now have a suite of functions, each returning a single path
kind. This makes it easy to move the python-path function into a
specific plugin in a follow-up commit.
All the users of GetLLDBPath were converted to call specific functions
instead. Most of them were hard-coding the enum value anyway, so this
conversion was simple. The only exception was SBHostOS, which I've
changed to use a switch on the incoming enum value.

SetFile has an optional style argument which defaulted to the native
style. This patch makes that argument mandatory so clients of the
FileSpec class are forced to think about the correct syntax.
At the same time this introduces a (protected) convenience method to
update the file from within the FileSpec class that keeps the current
style.
These two changes together prevent a potential pitfall where the style
might be forgotten, leading to the path being updated and the style
unintentionally being changed to the host style.
llvm-svn: 334663
With the recent changes in FileSpec to use LLVM's path style, it is
possible to delegate a bunch of common path operations to LLVM's path
helpers. This means we only have to maintain a single implementation and
at the same time can benefit from the efforts made by the rest of the
LLVM community.
This is part one of a set of patches. There was no obvious way to split
this so I just worked from top to bottom.

Summary:
This patch adds a modulemap which allows compiling the lldb headers into C++ modules
(for example in builds with LLVM_ENABLE_MODULES=On).
Even though most of the affected code has been cleaned up to work with the more strict
C++ module semantics, there are still some workarounds left in the current modulemap
(the most obvious one is the big `lldb` wrapper module).
It also moves the Obj-C++ files in lldb to their own subdirectories. This was necessary
because we need to filter out the modules flags for this code.
Note: With the latest clang and libstdc++ it seems necessary to have a STL C++ module
to get a working LLVM_ENABLE_MODULES build for lldb. Otherwise clang will falsely
detect ODR violations in the textually included STL code inside the lldb modules.

Summary:
This kind of functionality is useful to other project apart from clang.
LLDB works with version numbers a lot, but it does not have a convenient
abstraction for this. Moving this class to a lower level library allows
it to be freely used within LLDB.
Since this class is used in a lot of places in clang, and it used to be
in the clang namespace, it seemed appropriate to add it to the list of
adopted classes in LLVM.h to avoid prefixing all uses with "llvm::".
Also, I didn't find any tests specific for this class, so I wrote a
couple of quick ones for the more interesting bits of functionality.

When loading kexts in PlatformDarwinKernel, we use the BundleID as the
filename to to create shared modules. In GetSharedModule we call
ExamineKextForMatchingUUID for any BundleID it finds that is a match, to
see if the UUID is also a match. Until now we were using
Host::ResolveExecutableInBundle which calls a CoreFoundation API to
obtain the executable. However, it's possible that the executable has a
variant suffix (e.g. foo_development) and these files were ignored.
This patch replaces that call with logic that looks for all the binaries
in the bundle. Because of the way ExamineKextForMatchingUUID works, it's
fine to try to load executables that are not valid and we can just
iterate over the list until we found a match.
