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.

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.

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.

(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.

cannot be converted.
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.
llvm-svn: 140459
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.
