Douglas Gregor fd4344b5a6 Implement C++0x [temp.arg.template]p3, which allows slightly fuzzy 
matching of variadic template template parameters to template
arguments. This paragraph was the subject of ISO C++ committee
document N2555: Extending Variadic Template Template Parameters.

 2011-01-12 23:25:02 +00:00
Jason W Kim e9eae0f887 JimG sez: "The value-kinds look like masks, but they're not consistently used 
that way, unfortunately. If you want to change them to work additively instead
of a one-variant-kind-per-symbolref, that's great and I completely agree it's
worth doing, but it really should be a separate patch. Until then, this isn't
correct."

So I am reverting this bit until a more opportune time.

Douglas Gregor 4478f858b5 Add the location of the right parenthesis of a C++ named cast 
(static_cast, dynamic_cast, reinterpret_cast, or const_cast) to
improve source-location information. Fixes PR8960.

Jakob Stoklund Olesen 1a3534afc4 Sometimes, old virtual registers can linger on DBG_VALUE instructions. 
Make sure we don't crash in that case, but simply turn them into %noreg instead.

we'll go on this one.

Douglas Gregor 822d030118 Teach TreeTransform how to transform a pack expansion type into 
another pack expansion type. This can happen when rebuilding types in
the current instantiation.

Jay Foad 39c7980772 PR3558: mark "logically const" accessor methods in ASTContext as const, 
and mark the fields they use as mutable. This allows us to remove a few
const_casts.

Stephen Wilson a08cfb1299 Do not pass an invalid thread to Thread{Cancel,Join}. 
A race condition exists between StopReadThread and the reader thread proper.
When StopReadThread sets m_read_thread_enabled to false the reader thread can
terminate and set m_read_thread to LLDB_INVALID_HOST_THREAD on exit.  Thus calls
to ThreadCancel or ThreadJoin in StopReadThread can be passed an invalid handle.

This patch removes the race by using m_read_thread_enabled as the flag thru
which the reader thread can notify the parent thread of early/abnormal
termination.

Stephen Wilson c2204398e0 Initialize SymbolFileDWARFDebugMap on Apple platforms only. 
SymbolFileDWARFDebugMap handles the parsing of OSO stabs which are effectively a
Mach-O specific feature and is incompatible with other object file formats.

Stephen Wilson 78a4feb2c4 Log diagnostic when setting software breakpoints only on failure. 
Previously we would be posting a "FAILED" message to the log channel even when
the operation succeeded.

Also, take this opportunity to add braces thus eliminating an "ambiguous else"
compiler warning.

John McCall 20f6ab828a Fix a latent bug where, after emitting an expression statement, we would 
delete the block we began emitting into if it had no predecessors.  We never
want to do this, because there are several valid cases during statement
emission where an existing block has no known predecessors but will acquire
some later.  The case in my test case doesn't inherently fall into this 
category, because we could safely emit the case-range code before the statement
body, but there are examples with labels that can't be fallen into 
that would also demonstrate this bug.
