don't crash if we disable logging when some code already has a copy of the
logger. Prior to this fix, logs were handed out as pointers and if they were
held onto while a log got disabled, then it could cause a crash. Now all logs
are handed out as shared pointers so this problem shouldn't happen anymore.
We are also using our new shared pointers that put the shared pointer count
and the object into the same allocation for a tad better performance.

Howard Hinnant gave us changes for lldb_private::SharingPtr that gives us the ability have a single allocation contain both the class and the ref count without having to do intrusive pointer type stuff. They will intermingle correctly with other shared pointers as well. In order to take advantage of this you need to create your pointer in your class with the make_shared function:

       lldb_private::SharingPtr<A> p = llvm::make_shared<A>(i, j);

Currently up to five constructor arguments are supported and each must be an LValue.

identification of the test failures/errors by human beings as well as automatic

The prefix which identifies the type can be: Error, Failure, or ExpectedFailure.

so we don't end up with weak exports with some compilers.

thread descriptions.  This allows for correctly finding and obeying the last
filename-and-line marker from the debugger.

Add a delay for gud-up and gud-down.  This makes tracking filename-and-line
more reliable when moving up/down the stack.

that check pointer validity fail to parse.  Now
lldb does not crash in that case.  Also added
support for checking Objective-C class validity
in the Version 1 runtime as well as Version 2
runtimes with varying levels of available debug
support.

log timer increment true/false

llvm-svn: 118268

Added a top level Timer to the interpreter execute command.  Also added an option to pass the depth to "log timer enable".  That allows you to time just command execution with:

log timer enable 1
<command>
log timer dump

fixed them.  Added DISALLOW_COPY_AND_ASSIGN to classes that should
not be bitwise copied.  Added default initializers for member
variables that weren't being initialized in the ctor.  Fixed a few

adding support into lldb_private::Process:

    virtual uint32_t
    lldb_private::Process::LoadImage (const FileSpec &image_spec, 
                                      Error &error);

    virtual Error
    lldb_private::Process::UnloadImage (uint32_t image_token);

There is a default implementation that should work for both linux and MacOSX.
This ability has also been exported through the SBProcess API:

    uint32_t
    lldb::SBProcess::LoadImage (lldb::SBFileSpec &image_spec, 
                                lldb::SBError &error);

    lldb::SBError
    lldb::SBProcess::UnloadImage (uint32_t image_token);

Modified the DynamicLoader plug-in interface to require it to be able to 
tell us if it is currently possible to load/unload a shared library:

    virtual lldb_private::Error
    DynamicLoader::CanLoadImage () = 0;

This way the dynamic loader plug-ins are allows to veto whether we can 
currently load a shared library since the dynamic loader might know if it is
currenlty loading/unloading shared libraries. It might also know about the
current host system and know where to check to make sure runtime or malloc
locks are currently being held.

Modified the expression parser to have ClangUserExpression::Evaluate() be
the one that causes the dynamic checkers to be loaded instead of other code
that shouldn't have to worry about it.

RegisterContextLLDB holds a reference to the SymbolContext
in the vector of Cursors that UnwindLLDB maintains.  Switch
UnwindLLDB to hold a vector of shared pointers of Cursors
so this reference doesn't become invalid.

Correctly falling back from the "fast" UnwindPlan to the
"full" UnwindPlan when additional registers need to be
retrieved.

exception checks at the right time, and modified
ClangFunction so that it doesn't misinterpret the

llvm-svn: 118189

idea to also dump the session information for expected failures in addition to
failures and errors (tests with unexpected exceptions).

Modify the LLDBTestResult class which derives from unittest2.TextTestResult to
intercept the addExpectedFailure() method in order to mark the test instance as
needing its session information dumped.
