This seems to have broken Linux builds, which were failing with the following:

declarations that might lifetime-extend multiple temporaries. In passing, fix a
crasher (PR18217) if an initializer was dependent and exactly the wrong shape,
and remove a bogus function (Expr::findMaterializedTemporary) now its last use
is gone.

Previously, a line like
// expected-error-re {{foo}}
treats the entirety of foo as a regex. This is inconvenient when matching type
names containing regex characters. For example, to match
"void *(class test8::A::*)(void)" inside such a regex, one would have to type
"void \*\(class test8::A::\*\)\(void\)".
This patch changes the semantics of expected-error-re to only treat the parts
of the directive wrapped in double curly braces as regexes. This avoids the
escaping problem and leads to nicer patterns for those cases; see e.g. the
change to test/Sema/format-strings-scanf.c.
(The balanced search for closing }} of a directive also makes us handle the
full directive in test\SemaCXX\constexpr-printing.cpp:41 and :53.)

This allows to combine the edits when they can be different based on whether you saw
the implementation or not, e.g. with the designated initializer migration.

the ObjC implementation declarations, just don't change implementations for
classes that are not in the whitelisted headers.
For example, if we change a method to return 'instancetype' we should also
update the method definition in the implementation.

We were mistakengly giving linkonce_odr linkage instead of internal
linkage to the deleting and complete destructor thunks for classes in
anonymous namespaces.
Fixes PR17273.

Methods are thiscall by default in the MS ABI, and also in MinGW targetting GCC 4.7 or later.
This changes the diagnostic from the technically correct but hard to understand:
virtual function 'foo' has different calling convention attributes ('void ()') than the function it overrides (which has calling convention 'void () __attribute__((thiscall))')
to the more intuitive and also correct:
'static' member function 'foo' overrides a virtual function
We already have a test for this. Let's just run it in both ABI modes.

Includes might always pull in arbitrary header or data files outside of
modules. Among others, this includes builtin includes, which do not have
a module (story) yet.
Also cleanup implementation of ModuleMap::findModuleForHeader() to be
non-recursive.

This is an experimental feature, where -integrated-as will be
on by default on ARM/Thumb. We aim to detect the missing features
so that the next release is stable.
Updating the ReleaseNotes, too.
Also moving the AArch64 into the same place.

Specifically, we want to warn only for direct layering violations for
the modules we are calling clang on.
This temporarily unblocks
http://llvm-reviews.chandlerc.com/D2374
Once that is in, we'll also want to investigate whether to check the
layering in the build step of modules that we build transitively.

Prior to this patch, the alignment imposed by virtual bases only
included direct virtual bases. This patch fixes it to look at all
virtual bases.

array pointer by the right amount.

When parsing invalid top-level asm statements, we were ignoring the
return code of the SkipUntil we used for recovery. This led to crashes
when we hit the end of file and tried to continue parsing anyway.
This fixes the crash and adds a couple of tests for parsing related
problems.

That's a mouthful, and not necessarily the final name. This also
reflects a semantic change where this attribute is now on the
protocol itself instead of a class. This attribute will require
that a protocol, when adopted by a class, is explicitly implemented
by the class itself (instead of walking the super class chain).
Note that this attribute is not "done". This should be considered
a WIP.

Warn if both result expressions of a ternary operator (? :) are the same.
Because only one of them will be executed, this warning will fire even if
the expressions have side effects.

default initializers for other union members, handle anonymous unions with
anonymous struct members better. Fix a couple of semi-related bugs exposed by

In order to address latent bugs that were easier to expose in 64-bit
mode, we move the application of __declspec(align) to before the layout
of vbases rather than after.

The windows target does not support using an external assembler so
the test case was failing with this error:
error: there is no external assembler that can be used on this platform
The test was updated to always explicitly pass a target that has
both an interal and external assembler.

The standard is pretty clear on what it allows inside of template
arguments for non-type template parameters of pointer-to-member.
They must be of the form &qualified-id and cannot come from sources like
constexpr VarDecls or things of that nature.
This fixes PR18192.

With this patch we output the in the order

Which means that a destructor or constructor that call another is output after
the callee. This is a bit easier to read IHMO and a tiny bit more efficient
as we don't put a decl in DeferredDeclsToEmit.

Changed from:
keyword '__is_empty' will be treated as an identifier for the remainder of the translation unit
To:
keyword '__is_empty' will be made available as an identifier for the remainder of the translation unit
This is a more accurate description of clang's keyword compatibility feature,
given that some of the keywords are turned into context-sensitive keywords
(e.g. REVERTIBLE_TYPE_TRAIT) rather than being fully disabled.

Testing has revealed that large integral constants (i.e. > INT64_MAX)
are always mangled as-if they are negative, even in places where it
would not make sense for them to be negative (like non-type template
parameters of type unsigned long long).
To address this, we change the way we model number mangling: always
mangle as-if our number is an int64_t. This should result in correct
results when we have large unsigned numbers.
N.B. Bizarrely, things that are 32-bit displacements like vbptr offsets
are mangled as-if they are unsigned 32-bit numbers. This is a pretty
egregious waste of space, it would be a 4x savings if we could mangle it
like a signed 32-bit number. Instead, we explicitly cast these
displacements to uint32_t and let the mangler proceed.
llvm-svn: 196771
While testing our ability to mangle large constants (PR18175), I
incidentally discovered that we did not properly mangle enums correctly.
Previously, we would append the width of the enum in bytes after the
type-tag differentiator.
This would mean "enum : short" would be mangled as 'W2' while "enum :
char" would be mangled as 'W1'. Upon testing this with several versions
of MSVC, I found that this did not match their behavior: they always use
'W4'.
N.B. Quick testing uncovered that undname allows different numbers to
follow the 'W' in the following way:
'W0' -> "enum char"
'W1' -> "enum unsigned char"
'W2' -> "enum short"
'W3' -> "enum unsigned short"
'W4' -> "enum"
'W5' -> "enum unsigned int"
'W6' -> "enum long"
'W7' -> "enum unsigned long"
However this scheme appears abandoned, I cannot get MSVC to trigger it.
Furthermore, it's incomplete: it doesn't handle "bool" or "long long".
