We wouldn't properly save and restore the pending local instantiations
we had built up prior to instantiation of a variable definition. This
would lead to us instantiating too much causing crashes and other
general badness.
This fixes PR14374.

1) Use %clang_cc1 instead of the driver
2) Validate that the input contains a BOM
3) Validate that the BOM has been stripped from the output

We would fail to instantiate them when the surrounding function was
instantiated. Instantiate the class and add it's members to the list of
pending instantiations, they should be resolved when we are finished
with the function's body.
This fixes PR9685.

The warning from cmake-clang-x64-msc16-R was:

code for handling triviality, deletedness and constexpr. Fix a few bugs in
these, particularly related to mutable members, and remove some dead code.

GNU libc uses '__uptr' as a member name in C mode, conflicting with the
eponymous MSVC pointer modifier keyword.
Detect and mark the token as an identifier when these specific conditions are
met. __uptr will continue to work as a keyword for the remainder of the
translation unit.
Fixes PR17824.

The integrated assembler was already the default for win32. It is now able
to handle a clang bootstrap on mingw, so make it the default.

It wasn't possible for an anonymous type to show up inside of function arguments.
However, decltype (which MSVC added support for in 2010) makes this
possible. Further, backrefs to these anonymous types can now be formed.
This fixes PR18022.
N.B. We do not, and very likely _will not_, support MSVC's bug where
subsequent typedefs of anonymous types leak into the linkage name; this
is a gross violation of the ABI. A warning should be introduced to
inform our users of this particular shortcoming.

MSVC applies these to the following declaration only if present, otherwise
silently ignores them whereas we'll issue a warning.
Handling differs from ordinary attributes appearing in the same place, so add a
Sema test to make sure we get it right.

Clang knows how to use the gnu assembler directly from doing so on linux and
hurd. The existing support worked out of the box on cygwin and mingw and I was
able to bootstrap clang with it in both systems (with pending patches for the
new mingw abi, but that is independent of the assembler).

module. Use the marker to diagnose cases where we try to transition between
submodules when not at the top level (most likely because a closing brace was
missing at the end of a header file, but is also possible if submodule headers
attempt to do something fundamentally non-modular, like our .def files).

This is still an experimental attribute, but I wanted it in tree
for review. It may still get yanked.
This attribute can only be applied to a class @interface, not
a class extension or category. It does not change the type
system rules for Objective-C, but rather the implementation checking
for Objective-C classes that explicitly conform to a protocol.
During protocol conformance checking, clang recursively searches
up the class hierarchy for the set of methods that compose
a protocol. This attribute will cause the compiler to not consider
the methods contributed by a super class, its categories, and those
from its ancestor classes. Thus this attribute is used to force
subclasses to redeclare (and hopefully re-implement) methods if
they decide to explicitly conform to a protocol where some of those
methods may be provided by a super class.
This attribute intentionally leaves out properties, which are associated
with state. This attribute only considers methods (at least right now)
that are non-property accessors. These represent methods that "do something"
as dictated by the protocol. This may be further refined, and this
should be considered a WIP until documentation gets written or this
gets removed.
llvm-svn: 195533
attribute on method declaration and implementation
match. This makes no sense. Most annotations are
meant for declarations only and one is for implementation.
This has been constant source of regresions and hackery to
get around special cases. I am removing this check.
Such checks must be done on a case by case basis and
when it makes sense. For example, it makes sense
for availability/deprecated and I will file a radar
for that. // rdar://15531984
