LLVM/Clang. This brings in several fixes, including:
- Improvements in the Just-In-Time compiler's
allocation of memory: the JIT now allocates
memory in chunks of sections, improving its
ability to generate relocations. I have
revamped the RecordingMemoryManager to reflect
these changes, as well as to get the memory
allocation and data copying out fo the
ClangExpressionParser code. Jim Grosbach wrote
the updates to the JIT on the LLVM side.
- A new ExternalASTSource interface to allow LLDB to
report accurate structure layout information to
Clang. Previously we could only report the sizes
of fields, not their offsets. This meant that if
data structures included field alignment
directives, we could not communicate the necessary
alignment to Clang and accesses to the data would
fail. Now we can (and I have update the relevant
test case). Thanks to Doug Gregor for implementing
the Clang side of this fix.
- The way Objective-C interfaces are completed by
Clang has been made consistent with RecordDecls;
with help from Doug Gregor and Greg Clayton I have
ensured that this still works.
- I have eliminated all local LLVM and Clang patches,
committing the ones that are still relevant to LLVM
and Clang as needed.
I have tested the changes extensively locally, but
please let me know if they cause any trouble for you.

we handle Objective-C method calls. Currently,
LLDB treats the result of an Objective-C method
as unknown if the type information doesn't have
the method's signature. Now Clang can cast the
result to id if it isn't explicitly cast.
I also added a test case for this, as well as a
fix for a type import problem that this feature
exposed.

enhancements. With these enhancements, the return values
of Objective-C methods with unknown return types can be
implicitly cast to id for the purpose of making method
calls.
So what would have required this:
(int)[(id)[ClassWithNoDebugInfo methodReturningObject] methodReturningInt]
can now be written as:
(int)[[ClassWithNoDebugInfo methodReturningObject] methodReturningInt]

several patches. These patches fix a problem
where templated types were not being completed the
first time they were used, and fix a variety of
minor issues I discovered while fixing that problem.
One of the previous local patches was resolved in
the most recent Clang, so I removed it. The others
will be removed in due course.

to allow variables in the persistent variable store to know
how to complete themselves from debug information. That
fixes a variety of bugs during dematerialization of
expression results and also makes persistent variable and
result variables ($foo, $4, ...) more useful.
I have also added logging improvements that make it much
easier to figure out how types are moving from place to
place, and made some checking a little more aggressive.
The commit includes patches to Clang which are currently being
integrated into Clang proper; once these fixes are in Clang
top-of-tree, these patches will be removed. The patches don't
fix API; rather, they fix some internal bugs in Clang's
ASTImporter that were exposed when LLDB was moving types from
place to place multiple times.
