to handle non-caret diagnostics as well in order to be fully useful in
libclang etc. Also sketch out some more of my plans on this refactoring.

tracking the start and stop of macro expansion suppression. Also remove
the Columns variable which was just a convenience variable based on
DiagOpts. Instead we materialize it in the one piece of code that cared.

TextDiagnosticPrinter into the CaretDiagnostic class. Several
interesting results from this:

- This removes a significant per-diagnostic bit of state from the
  CaretDiagnostic class, which should eventually allow us to re-use the
  object.
- It removes a redundant recursive walk of the macro expansion stack
  just to compute the depth. We don't need the depth until we're
  unwinding anyways, so we can just mark when we reach it.
- It also paves the way for several simplifications we can do to how we
  implement the suppression.

Many targets use pseudo instructions to help register allocation.  Like
the COPY instruction, these pseudos can be expanded after register
allocation.  The early expansion can make life easier for PEI and the
post-ra scheduler.

This patch adds a hook that is called for all remaining pseudo
instructions from the ExpandPostRAPseudos pass.

llvm-svn: 140472

SDNodes may return values which are wider than the incoming element types. In
this patch we fix the integer promotion of these nodes.

Fixes spill-q.ll when running -promote-elements.

llvm-svn: 140471

No functional change intended.

llvm-svn: 140470

I'll fix the file contents in the next commit.

This pass is currently expanding the COPY and SUBREG_TO_REG pseudos. I
am going to add a hook so targets can expand more pseudo-instructions
after register allocation.

Many targets have pseudo-instructions that assist the register
allocator.  They can be expanded after register allocation, before PEI
and PostRA scheduling.

Also make sure we set the error flag when correcting a typo.

Implement Duncan's suggestion to use the result of getSetCCResultType if it is legal
(this is always the case for scalars), otherwise use the promoted result type.

Fix test/CodeGen/X86/vsplit-and.ll when promote-elements is enabled.

llvm-svn: 140464

When generating the trunc-store of i1's, we need to use the vector type and not
the scalar type.

This patch fixes the assertion in CodeGen/Generic/bool-vector.ll when
running with -promote-elements.

This is in preparation for overload resolution of initializer lists.
Currently, you will always get this message when you try to pass an init
list to an overloaded function.

the information on to Sema. There's still an incorrectness in the way template instantiation
works now, but that is due to a far larger underlying representational problem.
Also add a test case for various list initialization cases of scalars, which test this
commit as well as the previous one.

llvm-svn: 140460

Allow empty initializer lists for scalars, which mean value-initialization.
Constant evaluation for single-element and empty initializer lists for scalars.
Codegen for empty initializer lists for scalars.
Test case comes in next commit.

builds a semantic (structured) initializer list, just reports on whether it can match
the given list to the target type.
Use this mode for doing init list checking in the initial step of initialization, which
will eventually allow us to do overload resolution based on the outcome.

[microsoft] In Microsoft mode, if we are inside a template class member function and we can't resolve an identifier then assume the identifier is type dependent. The goal is to postpone name lookup to instantiation time to be able to search into type dependent base classes.

This fixes a few errors when parsing MFC code with clang.
BTW clang trunk is now about 5 patches away to be able the parse the default wizard-generated MFC project.

contents starting at an offset (2 separate methods). This helps
the scripting interface stay more natural by allowing both from
Python.

Added the ability to dump data with address annotations when
call SBData::GetDescription().

Hooked up the SBSection to the __repr__ so you can print section
objects from within python.

Improved the dumping of symbols from python.

Fixed the .i interface references which were set to "Relative to this Group"
which somehow included Jim's "lldb-clean" root directory in the path. The
interfaces are now in a folder called "interfaces" withing the Xcode API
subfolder.

SBModule supports an additional SBSection iteration, besides the original SBSymbol iteration.
Add docstrings and implement the two SBSection iteration protocols.

- New SBSection objects that are object file sections which can be accessed
  through the SBModule classes. You can get the number of sections, get a 
  section at index, and find a section by name.
- SBSections can contain subsections (first find "__TEXT" on darwin, then
  us the resulting SBSection to find "__text" sub section).
- Set load addresses for a SBSection in the SBTarget interface
- Set the load addresses of all SBSection in a SBModule in the SBTarget interface
- Add a new module the an existing target in the SBTarget interface
- Get a SBSection from a SBAddress object

This should get us a lot closer to being able to symbolicate using LLDB through
the public API.

llvm-svn: 140437

set a watchpoint Pythonically.  If the find-and-watch-a-variable operation
fails, an invalid SBValue is returned, instead.

Example Python usage:

        value = frame0.WatchValue('global',
                                  lldb.eValueTypeVariableGlobal,
                                  lldb.LLDB_WATCH_TYPE_READ|lldb.LLDB_WATCH_TYPE_WRITE)

Add TestSetWatchpoint.py to exercise this API.
We have 400 test cases now.
