In a subsequent commit, I will need to expose the search depth
to the SB API's, so I'm moving this define into lldb-enumerations
where it will get added to the lldb module.

function run.
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.

These three classes have no external dependencies, but they are used
from various low-level APIs. Moving them down to Utility improves
overall code layering (although it still does not break any particular
dependency completely).
The XCode project will need to be updated after this change.

This has multiple advantages:
- we need only one function argument/instance variable instead of three
- no need to default initialize variables
- no custom parsing code
- VersionTuple has comparison operators, which makes version comparisons much

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.

In r265181 the test for the NSCFBoolean data formatter was removed.
Later, in r279353 and r279446 a new implementation was provided for the
formatter, which I believe never worked (and this wasn't caught because
the test was never re-enabled).
This commit fixes the bug and re-enables the old test case.

Summary:
The Args class is used in plenty of places besides the command
interpreter (e.g., anything requiring an argc+argv combo, such as when
launching a process), so it needs to be in a lower layer. Now that the
class has no external dependencies, it can be moved down to the Utility
module.
This removes the last (direct) dependency from the Host module to
Interpreter, so I remove the Interpreter module from Host's dependency
list.

There's a bug in FindTypes, it ignores the exact flag if you pass a name that doesn't begin with
:: and pass eTypeClassAny for the type.
In this case we always know that the name we get from the vtable name is absolute so we can
work around the bug by prepending the "::". This doesn't fix the FindTypes bug.

This setting can be enabled like this at the target level:
(lldb) settings set target.experimental.use-modern-type-lookup true
This causes several new behaviors in the Clang expression parser:
- It completely disables use of ClangASTImporter. None are created
at all, and all users of it are now conditionalized on its
presence.
- It instead constructs a per-expression ExternalASTMerger, which
exists inside Clang and contains much of the type completion
logic that hitherto lived in ExternalASTSource,
ClangExpressionDeclMap, and ClangASTImporter.
- The expression parser uses this Merger as a backend for copying
and completing types.
- It also constructs a persistent ExternalASTMerger which is
connected to the Target's persistent AST context.
This is a major chunk of LLDB functionality moved into Clang. It
can be tested in two ways:
1. For an individual debug session, enable the setting before
running a target.
2. For the testsuite, change the option to be default-true. This
is done in Target.cpp's g_experimental_properties. The
testsuite is not yet clean with this, so I have not committed
that switch.
I have filed a Bugzilla for extending the testsuite to allow
custom settings for all tests:
https://bugs.llvm.org/show_bug.cgi?id=34771
I have also filed a Bugzilla for fixing the remaining testsuite
failures with this setting enabled:

The IR dynamic checks are self-contained functions whose job is to
- verify that pointers referenced in an expression are valid at runtime; and
- verify that selectors sent to Objective-C objects by an expression are
actually supported by that object.
These dynamic checks forward-declare all the functions they use and should not
require any external debug information. The way they ensure this is by marking
all the names they use with a dollar sign ($). The expression parser recognizes
such symbols and perform no lookups for them.
This patch fixes three issues surrounding the use of the dollar sign:
- to fix a MIPS issue, the name of the pointer checker was changed from
starting with $ to starting with _$, but this was not properly ignored; and
- the Objective-C object checker used a temporary variable that did not start
with $.
- the Objective-C object checker used an externally-defined struct (struct
objc_selector) but didn't need to.
The patch also implements some cleanup in the area:
- it reformats the string containing the Objective-C object checker,
which was mangled horribly when the code was transformed to a uniform width
of 80 columns, and
- it factors out the logic for ignoring global $-symbols into common code
shared between ClangASTSource and ClangExpressionDeclMap.

When introduced, breakpoint names were just tags that you could
apply to breakpoints that would allow you to refer to a breakpoint
when you couldn't capture the ID, or to refer to a collection of
breakpoints.
This change makes the names independent holders of breakpoint options
that you can then apply to breakpoints when you add the name to the
breakpoint. It adds the "breakpoint name configure" command to set
up or reconfigure breakpoint names. There is also full support for
then in the SB API, including a new SBBreakpointName class.
The connection between the name and the breakpoints
sharing the name remains live, so if you reconfigure the name, all the
breakpoint options all change as well. This allows a quick way
to share complex breakpoint behavior among a bunch of breakpoints, and
a convenient way to iterate on the set.
You can also create a name from a breakpoint, allowing a quick way
to copy options from one breakpoint to another.
I also added the ability to make hidden and delete/disable protected
names. When applied to a breakpoint, you will only be able to list,
delete or disable that breakpoint if you refer to it explicitly by ID.
This feature will allow GUI's that need to use breakpoints for their
own purposes to keep their breakpoints from getting accidentally
disabled or deleted.

The Timer destructor would grab a global mutex in order to update

class adds itself to an atomic singly linked list, and thus subsequent

This renames the LLDB error class to Status, as discussed
on the lldb-dev mailing list.
A change of this magnitude cannot easily be done without
find and replace, but that has potential to catch unwanted
occurrences of common strings such as "Error". Every effort
was made to find all the obvious things such as the word "Error"
appearing in a string, etc, but it's possible there are still
some lingering occurences left around. Hopefully nothing too
serious.

Summary:
The runtime discovers contexts through RenderScriptRuntime::Capture*()
methods. These methods see the low-level context representation.
However, the runtime calls APIs that require the high-level context
representation. Therefore, it needs to call yet another API to find
the high-level representation associated with a given low-level
representation.

This adjusts header file includes for headers and source files
in Core. In doing so, one dependency cycle is eliminated
because all the includes from Core to that project were dead
includes anyway. In places where some files in other projects
were only compiling due to a transitive include from another
header, fixups have been made so that those files also include
the header they need. Tested on Windows and Linux, and plan
to address failures on OSX and FreeBSD after watching the

This functionality is subsumed by DataBufferLLVM, which is
also more efficient since it will try to mmap. However, we
don't yet support mmaping writable private sections, and in
some cases we were using ReadFileContents and then modifying
the buffer. To address that I've added a flag to the
DataBufferLLVM methods that allow you to map privately, which
disables the mmaping path entirely. Eventually we should teach
DataBufferLLVM to use mmap with writable private, but that is
orthogonal to this effort.

classes from Core -> Utility, we have to separate the low-level

few functions required anything other than reading/writing

more appropriate area. Specifically, Dump() and DumpHexBytes()
are moved into free functions in Core/DumpDataExtractor.cpp,
and GetGNUEHPointer is moved into a static function in the
only file that it's referenced from.

Summary:
We've had two ways to print a "debug" log message.
- Log::GetDebug() was testing a Stream flag which was never set.
- Log::Debug() was checking for the presence of "log enable --debug"
flag.
Given that these two were used very rarely and we already have a
different way to specify "I want a more verbose log", I propose to remove
these two functions and migrate the callers to LLDB_LOGV. This commit
does that.

Summary:
Per discussion in D28616, having two ways two request logging (log
enable lldb XXX verbose && log enable -v lldb XXX) is confusing. This
removes the first option and standardizes all code to use the second
one.
I've added a LLDB_LOGV macro as a shorthand for if(log &&
log->GetVerbose()) and switched most of the affected log statements to
use that (I've only left a couple of cases that were doing complex
computations in an if(log) block).

This moves the following classes from Core -> Utility.
ConstString
Error
RegularExpression
Stream
StreamString
The goal here is to get lldbUtility into a state where it has
no dependendencies except on itself and LLVM, so it can be the
starting point at which to start untangling LLDB's dependencies.
These are all low level and very widely used classes, and
previously lldbUtility had dependencies up to lldbCore in order
to use these classes. So moving then down to lldbUtility makes
sense from both the short term and long term perspective in
solving this problem.
