more explicitly, but this is split out because it's mostly mechanical.
Because of the move to Serialization we can no longer abuse the
Preprocessor to forward it to the ASTReader. Besides the rename and

As discussed in https://reviews.llvm.org/D57112#inline-506781,
'flush' clause does not exist in the OpenMP spec, it can not be
specified, and `OMPFlushClause` class is just a helper class.
Now, here's the caveat. I have read @ABataev's

as if that clause is pseudo clause that only exists for the sole
purpose of simplifying the parser. As in, it never reaches AST.
I did not however try to verify that. Too bad, i was wrong.
It absolutely *does* reach AST. Therefore my understanding/justification
for the change was flawed, which makes the patch a regression which **must** be reverted.
@gribozavr has brought that up again in https://reviews.llvm.org/D57112#inline-521238

Then, as a consequence, remove the complex set of workarounds for
initialization order -- which are apparently not 100% reliable.
The only downside is that some of the member functions are now
specific to kNumElem == 2, and will need to be updated if that
constant is increased in the future.
Unfortunately, the current code caused an initialization-order runtime
failure for me in some compilation modes. It appears that in a
toolchain without init-array enabled, the order of initialization of
static data members of a template can be reversed w.r.t. the order
within a file.
This caused e.g. SanitizerKind::CFI to be initialized to 0.
I'm not quite sure if that is an allowable ordering variation, or
nonconforming behavior, but in any case, making everything constexpr
eliminates the possibility of such an issue.

llvm-svn: 354265
Summary:
The main effect is that clang now accepts the following conforming C11
code with MSVC headers:
#include <assert.h>
static_assert(1, "true");
This is a non-conforming extension (the keyword is outside the
implementer's namespace), so it is placed under -fms-compatibility
instead of -fms-extensions like most MSVC-specific keyword extensions.
Normally, in C11, the compiler is supposed to provide the _Static_assert
keyword, and assert.h should define static_assert to _Static_assert.
However, that is not what MSVC does, and MSVC doesn't even provide
_Static_assert.
This also has the less important side effect of enabling static_assert
in C++98 mode with -fms-compatibility. It's exceptionally difficult to
use modern MSVC headers without C++14 even, so this is relatively
unimportant.

This attribute applies to declarations of C stdlib functions
(sprintf, memcpy...) that have known fortified variants
(__sprintf_chk, __memcpy_chk, ...). When applied, clang will emit
calls to the fortified variant functions instead of calls to the

In GCC, this is done by adding gnu_inline-style wrapper functions,

support __builtin_va_arg_pack (and have no intention to).
This attribute takes two arguments, the first is 'type' argument
passed through to __builtin_object_size, and the second is a flag
argument that gets passed through to the variadic checking variants.

Summary:
r347205 fixed a bug in FileManager: first calling
getFile(shouldOpen=false) and then getFile(shouldOpen=true) results in
the file not being open.
Unfortunately, some code was (inadvertently?) relying on this bug: when
building with a PCH, the file entries are obtained first by passing
shouldOpen=false, and then later shouldOpen=true, without any intention
of reading them. After r347205, they do get unneccesarily opened.
Aside from extra operations, this means they need to be closed. Normally
files are closed when their contents are read. As these files are never
read, they stay open until clang exits. On platforms with a low
open-files limit (e.g. Mac), this can lead to spurious file-not-found
errors when building large projects with PCH enabled, e.g.
https://bugs.chromium.org/p/chromium/issues/detail?id=924225
Fixing the callsites to pass shouldOpen=false when the file won't be
read is not quite trivial (that info isn't available at the direct
callsite), and passing shouldOpen=false is a performance regression (it
results in open+fstat pairs being replaced by stat+open).
So an ideal fix is going to be a little risky and we need some fix soon
(especially for the llvm 8 branch).
The problem addressed by r347205 is rare and has only been observed in
clangd. It was present in llvm-7, so we can live with it for now.

With commit r351627, LLVM gained the ability to apply (existing) IPO
optimizations on indirections through callbacks, or transitive calls.
The general idea is that we use an abstraction to hide the middle man
and represent the callback call in the context of the initial caller.
It is described in more detail in the commit message of the LLVM patch
r351627, the llvm::AbstractCallSite class description, and the
language reference section on callback-metadata.
This commit enables clang to emit !callback metadata that is
understood by LLVM. It does so in three different cases:
1) For known broker functions declarations that are directly
generated, e.g., __kmpc_fork_call for the OpenMP pragma parallel.
2) For known broker functions that are identified by their name and
source location through the builtin detection, e.g.,
pthread_create from the POSIX thread API.
3) For user annotated functions that carry the "callback(callee, ...)"
attribute. The attribute has to include the name, or index, of
the callback callee and how the passed arguments can be
identified (as many as the callback callee has). See the callback
attribute documentation for detailed information.

Usual arithmetic rules do not apply to binary operations when one of the

Support the Swift calling convention on Windows ARM and AArch64. Both
of these conform to the AAPCS, AAPCS64 calling convention, and LLVM has
been adjusted to account for the register usage. Ensure that the
frontend passes this into the backend. This allows the swift runtime to
be built for Windows.

The Entry pointer in IdentifierInfo was only null for IdentifierInfo
created from a PTH. Now that PTH support has been removed we can remove
some PTH specific code in IdentifierInfo::getLength and
IdentifierInfo::getNameStart.
Also make the constructor of IdentifierInfo private to make sure that
they are only created by IdentifierTable, and move it to the header so
that it can be inlined in IdentifierTable::get and IdentifierTable::getOwn.

This patch addresses a compilation error with clang when
running in Haiku being unable to compile code using
float128 (throws compilation error such as 'float128 is
not supported on this target').

As of rev. 268898, clang supports __float128 on SystemZ. This seems to
have been in error. GCC has never supported __float128 on SystemZ,
since the "long double" type on the platform is already IEEE-128. (GCC
only supports __float128 on platforms where "long double" is some other
data type.)
For compatibility reasons this patch removes __float128 on SystemZ
again. The test case is updated accordingly.

The two LLVM_DUMP_METHOD methods have a undefined reference on clang::DiagnosticsEngine::DiagStateMap::dump.
tools/clang/tools/extra/clangd/benchmarks/IndexBenchmark links in
clangDaemon but does not link in clangBasic explicitly, which causes a
linker error "undefined symbol" in !NDEBUG + -DBUILD_SHARED_LIBS=on builds.
Move LLVM_DUMP_METHOD methods to .cpp to fix IndexBenchmark. They should
be unconditionally defined as they are also used by non-dump-method #pragma clang __debug diag_mapping

Summary:
Absolute path information for virtual files were missing even if we
have already stat'd the files. This patch puts that information for virtual
files that can succesffully be stat'd.
