MSVC has complained the definition of "inline const DiagnosticBuilder &operator<<(const DiagnosticBuilder &DB, CanQualType T)" in clang/AST/CanonicalType.h.

We had been generating load/store instructions with the default alignment
for the vector element type, even when the pointer argument had less alignment.

- Move the offending methods out of line and fix transitive includers.
- This required changing an enum in the PPCallback API into an unsigned.
llvm-svn: 149782
Fix all the files that depended on transitive includes of Diagnostic.h.
With this patch in place changing a diagnostic no longer requires a full rebuild of the StaticAnalyzer.

Let ASTContext allocate the storage in its BumpPtrAllocator.
This will help us remove ASTContext's depedency on PartialDiagnostic.h soon.

value of class type, look for a unique conversion operator converting to
integral or unscoped enumeration type and use that. Implements [expr.const]p5.
Sema::VerifyIntegerConstantExpression now performs the conversion and returns
the converted result. Some important callers of Expr::isIntegralConstantExpr
have been switched over to using it (including all of those required for C++11
conformance); this switch brings a side-benefit of improved diagnostics and, in
several cases, simpler code. However, some language extensions and attributes
have not been moved across and will not perform implicit conversions on
constant expressions of literal class type where an ICE is required.
In passing, fix static_assert to perform a contextual conversion to bool on its
argument.

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.

cache disassemblers according to the string value
of the target triple, not according to the enum
of the triple CPU. The reason for this is that
certain attributes of the instruction set are not
reflected in the enum, but only in the string.

array new expression. This lays some groundwork for the implicit conversion to
integral or unscoped enumeration which C++11 ICEs undergo.

A live range that has an early clobber tied redef now looks like a
normal tied redef, except the early clobber def uses the early clobber
slot.
This is enough to handle any strange interference problems.
llvm-svn: 149769
I don't have a test that fails because of this, but a test case like
CodeGen/X86/2009-12-01-EarlyClobberBug.ll exposes the problem. EAX is
redefined by a tied early clobber operand on inline asm, and the live
range should look like this:
%EAX,inf = [48r,64e:0)[64e,80r:1) 0@48r 1@64e
Previously, the two values got merged:
%EAX,inf = [48r,80r:0) 0@48r
With this bug fixed, the REDEF_BY_EC VNInfo flag is no longer needed.

new, is well-formed with defined semantics of throwing (a type which can be
caught by a handler for) std::bad_array_new_length, unlike in C++98 where it is
somewhere nebulous between undefined behavior and ill-formed.
If the array size is an integral constant expression and satisfies one of these
criteria, we would previous the array new expression, but now in C++11 mode, we
merely issue a warning (the code is still rejected in C++98 mode, naturally).
We don't yet implement new C++11 semantics correctly (see PR11644), but we do
implement the overflow checking, and (for the default operator new) convert such
expressions to an exception, so accepting such code now does not seem especially
unsafe.

Andy, in a previous commit you made this into an ImmutablePass so that you could
add it to the PassManager, then in the next commit you left it a Pass but
removed the code that added it to the PM. If you do add it to the PM then the PM
should take care of deleting it, but it's also true that nothing in codegen
needs this object to exist after it's done its work here. It's not clear to me
which design you want; this should likely either cease to be a Pass or be added
to the PM where other parts of CodeGen will request it.

If a value is defined by a COPY, that instuction can easily and cheaply
be found by getInstructionFromIndex(VNI->def).
This reduces the size of VNInfo from 24 to 16 bytes, and improves
llc compile time by 3%.

By default, boost the chain depth contribution of loads and stores. This will allow a load/store pair to vectorize even when it would not otherwise be long enough to satisfy the chain depth requirement.

Changed the lldb.SBModule.section[<str>] property to return a single section.
Added a lldb.SBSection.addr property which returns an lldb.SBAddress object.

Passes prior to instructon selection are now split into separate configurable stages.
Header dependencies are simplified.
The bulk of this diff is simply removal of the silly DisableVerify flags.
Sorry for the target header churn. Attempting to stabilize them.

Don't form an out of bounds pointer just to test if it
would be out of bounds.
Also perform the same bounds checking for all the previous
mapped structures.
