What follows bellow is a correctness proof of the transform using CVC3.
$ < t.cvc
A, B : BITVECTOR(32);
QUERY BVPLUS(32, A & B, A | B) = BVPLUS(32, A, B);
$ cvc3 < t.cvc
Valid.

There are no variable values like registers encoded in the low 32 bits of MUBUF
instructions, so it is relatively easy to check these bits, and it will
help prevent us from introducing encoding bugs.

This bit was left uninitialized, which was causing some random failures
of piglit tests.
NOTE: This is a candidate for the 3.5 branch.

This patch adds a new property: isRegSequence and the related target hooks:
TargetIntrInfo::getRegSequenceInputs and
TargetInstrInfo::getRegSequenceLikeInputs to specify that a target specific
instruction is a (kind of) REG_SEQUENCE.

anyway. If -ast-dump *is* also provided, then dump the AST declarations as well
as the lookup results. This is invaluable for cross-correlating the lookup
information with the declarations actually found.

(dropping const from the reference as MemoryBuffer is immutable already,
so const is just redundant - and while I'd personally put const
everywhere, that's not the LLVM Way (see llvm::Type for another example
of an immutable type where "const" is omitted for brevity))
Changing the pointer argument to a reference parameter makes call sites
identical between callers with unique_ptrs or raw pointers, minimizing
the churn in a pending unique_ptr migrations.

And in the process, discover that FileManager::removeStatCache had a
double-delete when removing an element from the middle of the list (at
the beginning or the end of the list, there was no problem) and add a
unit test to exercise the code path (which successfully crashed when run
(with modifications to match the old API) without this patch applied)

buildLocationLists easier to read.
The previous implementation conflated the merging of individual pieces
and the merging of entire DebugLocEntries.
By splitting this functionality into two separate functions the intention
of the code should be clearer.

For many Thumb-1 register register instructions, setting the CPSR is not
permitted inside an IT block. We would not correctly flag those instructions.
The previous change to identify this scenario was insufficient as it did not
actually catch all the instances. The current list is formed by manual
inspection of the ARMv6M ARM.
The change to the Thumb2 IT block test is due to the fact that the new more
stringent checking of the MIs results in the If Conversion pass being prevented
from executing (since not all the instructions in the BB are predicable). This
results in code gen changes.
Thanks to Tim Northover for pointing out that the previous patch was
insufficient and hinting that the use of the v6M ARM would be much easier to use
than the v7 or v8!

The patch adds new features in asan-symbolizer script which are helpful for using ASan on embedded systems:
1) add cross-compile prefix for binutils
2) define path to sysroot with sanitized binaries
Features are enabled by command line options.
The patch also extends command line interface with help option.

Clang used a custom implementation of lookup when handling designated
initializers. The custom code was not particularly optimized and relied
on standard lookup for typo-correction anyway.
This custom code has to go, it doesn't properly support MSVC-style
anonymous structs embedded inside other records; replace it with the
typo-correction path.
This has the side effect of speeding up semantic handling of the fields
for a designated initializer while simplifying the code at the same
time.
This fixes PR20573.

Summary:
Just like with -finput-charset=UTF-8 in review http://reviews.llvm.org/D4347, I think we should just ignore it when UTF-8 is provided.

Okay, so this actually does more than just that. I've rearranged most of
the information on the page to try to make it more helpful and flow
better. Essentially, the differences between Mac and Linux, the various
ABI libraries, and in-tree versus out-of-tree builds were cluttering
things. To clean up, I've done the following:
* Only describe the cmake process. buildit doesn't work out of the box
on Linux, and we need to stop having duplicates for every process.
* Use libc++abi for the default instructions. This works on the major
platforms.
* Describe both in-tree and out-of-tree builds. Previously it wasn't
clear that in-tree builds were even possible for libc++.
* Separate the documentation about using libc++ from that about
building and testing libc++.

In cases like:
struct C { ~C(); }
void f(C c = C());
void t() {
f();
}
We currently do not add the CXXBindTemporaryExpr for the temporary (the
code mentions that as the default parameter expressions are owned by
the declaration, we'd otherwise add the same expression multiple times),
but we add the temporary destructor pointing to the CXXBindTemporaryExpr.
We need to fix that before we can re-enable the assertion.
