Greg Clayton c44bcec6e1 LLDB top of tree SVN fails to attach to a MacOSX native process by pid only (no executable).
The problem was that the static DynamicLoaderDarwinKernel::Initialize() was recently changed to come before DynamicLoaderMacOSXDYLD::Initialize() which caused the DynamicLoaderDarwinKernel::CreateInstance(...) to be called before DynamicLoaderMacOSXDYLD::CreateInstance(...) and DynamicLoaderDarwinKernel would claim it could be the dynamic loader for a user space MacOSX process. The fix is to make DynamicLoaderDarwinKernel::CreateInstance() a bit more thourough when vetting the process so that it doesn't claim MacOSX user space processes.

Jim Ingham e5ee6f04ab Figure out what the fixed expression is, and print it. Added another target setting to
quietly apply fixits for those who really trust clang's fixits.

Also, moved the retry into ClangUserExpression::Evaluate, where I can make a whole new ClangUserExpression 
to do the work.  Reusing any of the parts of a UserExpression in situ isn't supported at present.

Greg Clayton fee32cd9e2 When creating typedefs, don't call Type::GetName() since that might recursively call "lldb_private::Type::ResolveClangType(lldb_private::Type::ResolveStateTag)" and cause a crash. A lldb_private::Type should have a valid name if it is created without a backing CompilerType. Also provide a name that we can recognize so if we see it in a as the typename of a variable, we will know to check it out. This crash is happening quite a bit and we need to determine if this is due to incorrect debug info, or just due to some bug in LLDBD.

Pavel Labath 6315e7f000 Revert the "build fix" in r264104
this was needed because lldb-mi temporarily contained references to private lldb symbols
(lldb_private namespace), which it shouldn't have. The situation has since been rectified and
this wasn't the right fix anyway, since it can lead to funny ODR violations.

Pavel Labath eb0c5c8776 Fix infinite recursion in DWO file parsing
Summary:
Since r264316, clang started adding DW_AT_GNU_dwo_name attribute to dwo files (previously, this
attribute was only present in main object files), breaking pretty much every dwo test. The
problem was that we were treating the presence of said attribute as a signal that we should look
for information in an external object file, and caused us to enter an infinite loop. I fix this
by making sure we do not go looking for an external dwo file if we already *are* parsing a dwo
file.

Zachary Turner d133f6acf1 Move some functions from DWARFASTParserClang to ClangASTImporter.
This allows these functions to be re-used by a forthcoming
PDBASTParser.  The functions in question are CanCompleteType,
CompleteType, and CanImport.  Conceptually, these functions belong
on ClangASTImporter anyway, and previously they were just ping
ponging around through a few levels of indirection to end up there
as well, so this patch actually makes the code somewhat simpler.

A few methods were moved to a new file called ClangUtil, so that
they can be shared between ClangASTImporter and ClangASTContext
without creating a circular dependency between those two cpp
files.

Sean Callanan 863fab69a2 Expose top-level Clang expressions via the command line and the API.
Top-level Clang expressions are expressions that act as new translation units,
and define their own symbols.  They do not have function wrappers like regular
expressions do, and declarations are persistent regardless of use of the dollar
sign in identifiers.  Names defined by these are given priority over all other
symbol lookups.

This patch adds a new expression option, '-p' or '--top-level,' which controls
whether the expression is treated this way.  It also adds a flag controlling 
this to SBExpressionOptions so that this API is usable externally.  It also adds
a test that validates that this works.  (The test requires a fix to the Clang
AST importer which I will be committing shortly.)

Sean Callanan d0234c4593 When we import the definition for a Tagdecl, propagate its completeness too.
The ASTImporter completes the full definiton for a TagDecl in several places,
including the type-deport logic.  When this happens, we should also propagate
the bit that says that this is a complete definition.  This makes (for example)
lambdas callable.

Sean Callanan 47cca78efa Record all translation units with more than one function in them (e.g., blocks).
Blocks and lambdas have their implementation functions stored in the IR for an
expression.  If we put the block/lambda into a result variable it needs to stay
around.  As a heuristic, remember any execution unit that has more than one
function in it.

Stephane Sezer 65fd8f4345 Fix FILE * leak in Python API
Summary:
This fixes a leak introduced by some of these changes:
r257644
r250530
r250525

The changes made in these patches result in leaking the FILE* passed
to SetImmediateOutputFile. GetStream() will dup() the fd held by the
python caller and create a new FILE*. It will then pass this FILE*
to SetImmediateOutputFile, which always uses the flag
transfer_ownership=false when it creates a File from the FILE*.

Since transfer_ownership is false, the lldb File destructor will not
close the underlying FILE*. Because this FILE* came from a dup-ed fd,
it will also not be closed when the python caller closes its file.

Leaking the FILE* causes issues if the same file is used multiple times
by different python callers during the same lldb run, even if these
callers open and close the python file properly, as you can end up
with issues due to multiple buffered writes to the same file.

those you have to get right when you make them.

This is just a first stage.  At present the fixits are applied silently.  The next step

This patch adds ThreadSanitizer support into LLDB:

- A breakpoint stops in `__tsan_on_report`, then we extract all sorts of information by evaluating an expression. We then populate this into StopReasonExtendedInfo.
- SBThread gets a new API, SBThread::GetStopReasonExtendedBacktraces(), which returns TSan’s backtraces in the form of regular SBThreads. Non-TSan stop reasons return an empty collection.
- Added some test cases.

Sean Callanan 00294b34a3 Backend support for top-level Clang epxressions
This patch adds a new ExecutionPolicy, eExecutionPolicyTopLevel, which
tells the expression parser that the expression should be JITted as top
level code but nothing (except static initializers) should be run.  I
have modified the Clang expression parser to recognize this execution
policy.  On top of the existing patches that support storing IR and
maintaining a map of arbitrary Decls, this is mainly just patching up a
few places in the expression parser.

I intend to submit a patch for review that exposes this functionality
through the "expression" command and through the SB API.  That patch
also includes a testcase for all of this.
