In C mode clang fails to merge the textually included definition with the one imported from a module. The C lookup rules fail to find the imported definition because its linkage is internal in non C++ mode.
This patch reinstates some of the ODR merging rules for typedefs of anonymous tags for languages other than C++.
Patch by Raphael Isemann and me (D34510).

Combined directives like 'target parallel' have two captured statements.
Sema has to check the right one from the right direction.
Previously, Sema::IsOpenMPCapturedByRef would return false for mapped
scalars on combined directives. This results in a wrong signature of
the outlined function which triggers an assertion:
void llvm::CallInst::init(llvm::FunctionType *, llvm::Value *, ArrayRef<llvm::Value *>, ArrayRef<OperandBundleDef>, const llvm::Twine &): Assertion `(i >= FTy->getNumParams() || FTy->getParamType(i) == Args[i]->getType()) && "Calling a function with a bad signature!"' failed.
Fixes PR30975 (and PR31985). New function was taken from clang-ykt.

llvm-svn: 306948
Summary:
Depends on https://reviews.llvm.org/D34867.
Add a Clang frontend option to enable optimization remark hotness
thresholds, which were added to LLVM in https://reviews.llvm.org/D34867.
This prevents diagnostics that do not meet a minimum hotness
threshold from being output. When generating optimization remarks for large
codebases with a ton of cold code paths, this option can be used
to limit the optimization remark output at a reasonable size.

the target is 32-bit.
The following changes are made to the driver since 32-bit apps do not
run on iOS 11 or later:
- If the deployment target is set explicitly, either with a command-line
option or an environment variable, the driver should report an error
if the version is greater than iOS 10.
- In the case where the deployment target is not set explicitly and the
default is inferred from the target triple or SDK version, it should
use a maximum default of iOS 10.99.99.

Allow ODR for ObjC/C in the sense that we won't keep more that
one definition around (merge them). However, ensure the decl
pass the structural compatibility check in C11 6.2.7/1, for that,
reuse the structural equivalence checks used by the ASTImporter.
Few other considerations:
- Create error diagnostics for tag types mismatches and thread
them into the structural equivalence checks.
- Note that by doing this we only support redefinition between types
that are considered "compatible types" by C.
This is mixed approach of the suggestions discussed in

Redeclaration lookup should never find hidden enumerators in C, because
they do not have linkage (C11 6.2.2/6)
The linkage of an enumerator should be VisibleNoLinkage, and
isHiddenDeclarationVisible should be checking hasExternalFormalLinkage.

Summary:
This patch aims to fix the bug reported at
https://bugs.llvm.org/show_bug.cgi?id=33189. Clang hits an assertion
when a template destructor declaration is present. This is caused by
later processing that does not expect to encounter a template when
looking at a destructor. The resolution is to treat the destructor as
being not declared when later processing is interested in the properties
of the destructor of a class.

The root cause of the issues reported in D32406 and D34680 is that clang
instruments functions without bodies. Make it stop doing that, and also
teach it how to use old (incorrectly generated) profiles without
crashing.
llvm-svn: 306883
This is a short-term fix for PR33650 aimed to get the modules build bots green again.
Remove all the places where we use the LLVM_YAML_IS_(FLOW_)?SEQUENCE_VECTOR
macros to try to locally specialize a global template for a global type. That's
not how C++ works.
Instead, we now centrally define how to format vectors of fundamental types and
of string (std::string and StringRef). We use flow formatting for the former
cases, since that's the obvious right thing to do; in the latter case, it's
less clear what the right choice is, but flow formatting is really bad for some
cases (due to very long strings), so we pick block formatting. (Many of the
cases that were using flow formatting for strings are improved by this change.)
Other than the flow -> block formatting change for some vectors of strings,
this should result in no functionality change.

Corresponding LLVM change is r306878.
llvm-svn: 306881
Summary:
This patch introduces a few extra BraceWrapping options, similar to
`SplitEmptyFunction`, to allow merging empty 'record' bodies (e.g.
class, struct, union and namespace):
* SplitEmptyClass
* SplitEmptyStruct
* SplitEmptyUnion
* SplitEmptyNamespace
The `SplitEmptyFunction` option name has also been simplified/
shortened (from `SplitEmptyFunctionBody`).
These options are helpful when the correspond AfterXXX option is
enabled, to allow merging the empty record:
class Foo
{};
In addition, this fixes an unexpected merging of short records, when
the AfterXXXX options are used, which caused to be formatted like
this:
class Foo
{ void Foo(); };
This is now properly formatted as:
class Foo
{
void Foo();
};

Summary:
This patch tries to avoid binpacking when initializing lists/arrays, to allow things like:
static int types[] = {
registerType1(),
registerType2(),
registerType3(),
};
std::map<int, std::string> x = {
{ 0, "foo fjakfjaklf kljj" },
{ 1, "bar fjakfjaklf kljj" },
{ 2, "stuff fjakfjaklf kljj" },
};
This is similar to how dictionnaries are formatted, and actually corresponds to the same conditions: when initializing a container (and not just 'calling' a constructor).
Such formatting involves 2 things:
* Line breaks around the content of the block. This can be forced by adding a comma or comment after the last element
* Elements should not be binpacked
This patch considers the block is an initializer list if it either ends with a comma, or follows an assignment, which seems to provide a sensible approximation.

This fixes an issue with the emission of lifetime markers for struct-returning Obj-C msgSend calls. When the result of a struct-returning call is ignored, the temporary storage is only marked with lifetime markers in one of the two branches of the nil-receiver-check. The check is, however, not required when the result is unused. If we still need to emit the check (due to consumer arguments), let's not emit the memset to zero out the result if it's unused. This fixes a use-after-scope false positive with AddressSanitizer.

This is a more principled version of r303756. That change was both very
brittle about the state of the Diags object going into the driver and
also broke tooling in funny ways.
In particular it prevented tools from capturing diagnostics properly and
made the compilation database logic fail to provide arguments to the
tool, falling back to scanning directories for JSON files.

This introduces helper functions that set target defines for different ARMV8-A
architecture kinds. It fixes an issue that the v8.1 define ARM_FEATURE_QRDMX
was not set for v8.2. These helper functions make things more “scalable” if we
want to add ARMv8.3 at some point, and a cleanup has been done to hold the
architecture kind in one variable (instead of one for each).
