characters. I could find no newline character in a diagnostic message,
and adding an assert to this code never fires in the testsuite.

I think this code is essentially dead, and was previously used for
a different purpose. If I just don't understand how it is we can end up
with a newline here please let me know (with a test case?) and I'll
revert.

name as well. No functionality changed here.

This needs to be cleaned up to better use the ostream object, WIP.

I'm planning to switch a bunch of these over to use a raw_ostream
instead of += on a string object.

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.

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.

No functional change intended.

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.

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.

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.
