Alexey Bataev f33eba6573 [OPENMP] Additional processing of 'omp atomic write' directive.
According to OpenMP standard, Section 2.12.6, atomic Construct, '#pragma omp atomic write' is allowed to be used only for expression statements of form 'x = expr;', where x is a lvalue expression and expr is an expression with scalar type. Patch adds checks for it.

Alexis Hunt 724f14e75c Create a new 'flag_enum' attribute.
This attribute serves as a hint to improve warnings about the ranges of
enumerators used as flag types. It currently has no working C++ implementation
due to different semantics for enums in C++. For more explanation, see the docs
and testcases.

Tim Northover b047bfae32 AArch64: simplify PCS mapping.
Now that LLVM can count the registers needed to implement AAPCS rules, we don't
need to duplicate that logic here. This means we can drop the explicit padding
and also use more natural types in many cases (e.g. "struct { float arr[3]; }"
used to end up as "[2 x double]" to avoid holes on the stack.

The one wrinkle is that AAPCS va_arg was also using the register counting
machinery. But the local replacement isn't too bad.

David Majnemer 98e77a2512 MS ABI: Mangle char16_t and char32_t string literals
We previously had support for char and wchar_t string literals.  VS 2015
added support for char16_t and char32_t.

String literals must be mangled in the MS ABI in order for them to be
deduplicated across translation units: their linker has no notion of
mergeable section.  Instead, they use the mangled name to make a COMDAT
for the string literal; the COMDAT will merge with other COMDATs in
other object files.

This allows strings in object files generated by clang to get merged
with strings in object files generated by MSVC.

Frederic Riss d253ed6565 Fully handle globals and functions in CGDebugInfo::getDeclarationOrDefinition()
Currently this function would return nothing for functions or globals that
haven't seen a definition yet. Make it return a forward declaration that will
get RAUWed with the definition if one is seen at a later point. The strategy
used to implement this is similar to what's done for types: the forward
declarations are stored in a vector and post processed upon finilization to
perform the required RAUWs.

For now the only user of getDeclarationOrDefinition() is EmitUsingDecl(), thus
this patch allows to emit correct imported declarations even in the absence of
an actual definition of the imported entity.

(Another user will be the debug info generation for argument default values
that I need to resurect).

Justin Bogner 94d384e423 InstrProf: Don't emit coverage for uninstantiated templates
We include unused functions and methods in -fcoverage-mapping so that
we can differentiate between uninstrumented and unused. This can cause
problems for uninstantiated templates though, since they may involve
an incomplete type that can't be mangled. This shows up in things like
libc++'s <unordered_map> and makes coverage unusable.

Avoid the issue by skipping uninstantiated methods of a templated
class.

John McCall 0d8d6c094f Fix an assertion when ending a function definition.
The bug is that ExprCleanupObjects isn't always empty
in a fresh evaluation context.  New evaluation contexts just
track the current depth of the stack.

The assertion will misfire whenever we finish processing
a function body inside an expression that contained an earlier
block literal with non-trivial captures.  That's actually
a lot less likely than you'd think, though, because it has
to be a real function declaration, not just another block.
Mixed block/lambda code would work, as would a template
instantiation or a local class definition.

The code works correctly if the assertion is disabled.

Reid Kleckner d60b82f93e Handle use of default member initializers before end of outermost class
Specifically, when we have this situation:
  struct A {
    template <typename T> struct B {
      int m1 = sizeof(A);
    };
    B<int> m2;
  };

We can't parse m1's initializer eagerly because we need A to be
complete.  Therefore we wait until the end of A's class scope to parse
it. However, we can trigger instantiation of B before the end of A,
which will attempt to instantiate the field decls eagerly, and it would
build a bad field decl instantiation that said it had an initializer but
actually lacked one.

Fixed by deferring instantiation of default member initializers until
they are needed during constructor analysis. This addresses a long
standing FIXME in the code.

Fixes PR19195.

Summary:
Ok, here is somewhat addition to D6217 aiming to preserve old darwin behavior wrt the typedefed types. The actual change to SemaChecking turned out to be pretty gross, in particular:
  1. We need to extract the typedef'ed type for proper diagnostics
  2. We need to walk over paren expressions as well

Bill Schmidt 8ff672d397 [PowerPC] Enable vec_perm for long long and double vector types for VSX
VSX makes the "vector long long" and "vector double" types available.
This patch enables the vec_perm interface for these types.  The same
builtin is generated regardless of the specified type, so no
additional work or testing is needed in the back end.  Tests are added
to ensure this builtin is generated by the front end.

Richard Smith 6403e937d6 PR21565 Add an egregious hack to support broken libstdc++ headers that declare
a member named 'swap' and then expect unqualified lookup for the name 'swap' in
its exception specification to find anything else.

Without delay-parsed exception specifications, this was ill-formed (NDR) by
[basic.scope.class]p1, rule 2. With delay-parsed exception specifications, the
call to 'swap' unambiguously finds the function being declared, which then
fails because the arguments don't work for that function.
