The version number is needed when a single AST node is visited multiple
times and is used to create APValues that are required to be distinct
from each other (for example, MaterializeTemporaryExprs in default

This patch fixes a bug in r328731 that caused structs transitively
containing __weak fields to be passed in registers. The patch replaces
the flag RecordDecl::CanPassInRegisters with a 2-bit enum that indicates
whether the struct or structs containing the struct are forced to be
passed indirectly.
This reapplies r329617. r329617 didn't specify the underlying type for
enum ArgPassingKind, which caused regression tests to fail on a windows
bot.

-fsanitize=kernel-address
Summary:
Right now to disable -fsanitize=kernel-address instrumentation, one needs to use no_sanitize("kernel-address"). Make either no_sanitize("address") or no_sanitize("kernel-address") disable both ASan and KASan instrumentation. Also remove redundant test.

This reverts commit r329289.
It was decided that we shouldn't expose the __has_* traits to C since
they are deprecated and useless.

I believe all the pieces are now in place in the backend to make this work correctly. We can either mask the input to 32 bits for pmuludg or shl/ashr for pmuldq and use a regular mul instruction. The backend should combine this to PMULUDQ/PMULDQ and then SimplifyDemandedBits will remove the and/shifts.

Summary:
The FileID/Offset conversion is lossy. The code takes the fileLoc, which loses
e.g. the spelling location in some macro cases.
Instead, pass the original SourceLocation which preserves all information, and
update consumers to match current behavior.
This allows us to fix two bugs in clangd that need the spelling location.

Summary:
This change consolidates the always/never lists that may be provided to
clang to externally control which functions should be XRay instrumented
by imbuing attributes. The files follow the same format as defined in
https://clang.llvm.org/docs/SanitizerSpecialCaseList.html for the
sanitizer blacklist.
We also deprecate the existing `-fxray-instrument-always=` and
`-fxray-instrument-never=` flags, in favour of `-fxray-attr-list=`.
This fixes http://llvm.org/PR34721.

Summary:
This patch cleans up a bunch of dead or unused code in BuildAnonymousStructUnionMemberReference.
The dead code was a branch that built a new CXXThisExpr when we weren't given a base object expression or base variable.
However, BuildAnonymousFoo has only two callers. One of which always builds a base object expression first, the second only calls when the IndirectFieldDecl is not a C++ class member. Even within C this branch seems entirely unused.
I tried diligently to write a test which hit it with no success.
This patch removes the branch and replaces it with an assertion that we were given either a base object expression or a base variable.

instantiation.
Summary:
Currently Clang fails to propagate qualifiers from the `CXXThisExpr` to the rebuilt `FieldDecl` for IndirectFieldDecls. For example:
```
template <class T> struct Foo {
struct { int x; };
int y;
void foo() const {
static_assert(__is_same(int const&, decltype((y))));
static_assert(__is_same(int const&, decltype((x)))); // assertion fails
}
};
template struct Foo<int>;
```
The fix is to delegate rebuilding of the MemberExpr to `BuildFieldReferenceExpr` which correctly propagates the qualifiers.

self-assignment (classes)
Summary:
This has just bit me, so i though it would be nice to avoid that next time :)
Motivational case:
https://godbolt.org/g/cq9UNk
Basically, it's likely to happen if you don't like shadowing issues,
and use `-Wshadow` and friends. And it won't be diagnosed by clang.
The reason is, these self-assign diagnostics only work for builtin assignment
operators. Which makes sense, one could have a very special operator=,
that does something unusual in case of self-assignment,
so it may make sense to not warn on that.
But while it may be intentional in some cases, it may be a bug in other cases,
so it would be really great to have some diagnostic about it...

-cc1gen-reproducer driver option
The recommit fixes:
- An MSAN failure (CCPrintOptions wasn't initialized in the Driver)
- Ensures that the strings in the libclang invocation files are escaped
Original message:
This commit is a follow up to the previous work that recorded Libclang invocations
into temporary files: r319702.
It adds a new -cc1 mode to clang: -cc1gen-reproducer. The goal of this mode is to generate
Clang reproducer files for Libclang tool invocation. The JSON format in the invocation
files is not really intended to be stable, so Libclang and Clang should be of the same version
when generating reproducers.
The new mode emits the information about the temporary files and Libclang-specific information
to stdout using JSON.

Summary:
`ASTPrinter` allows setting the ouput to any O-Stream, but that printer creates source-code-like syntax (and is also marked with a `FIXME`). The nice, colourful, mostly human-readable `ASTDumper` only works on the standard output, which is not feasible in case a user wants to see the AST of a file through a code navigation/comprehension tool.
This small addition of an overload solves generating a nice colourful AST block for the users of a tool I'm working on, [[ http://github.com/Ericsson/CodeCompass | CodeCompass ]], as opposed to having to duplicate the behaviour of definitions that only exist in the anonymous namespace of implementation TUs related to this module.

Summary:
This change introduces `-fxray-link-deps` and `-fnoxray-link-deps`. The
`-fnoxray-link-deps` allows for directly controlling which specific XRay
runtime to link. The default is for clang to link the XRay runtime that
is shipped with the compiler (if there are any), but users may want to
explicitly add the XRay dependencies from other locations or other
means.

We track on the AggValueSlot (and through a couple of other

share its tail padding with some other object, so that we can avoid
emitting stores into the tail padding if that's the case. We still
widen stores into tail padding when we can do so.

The new rules say that a standard-layout struct has its first non-static
data member and all base classes at offset 0, and consider a class to
not be standard-layout if that would result in multiple subobjects of a

We track "is C++11 standard-layout class" separately from "is

Summary:
Previously, `clang-format` didn't understand lightweight
Objective-C generics, which have the form:
```
@interface Foo <KeyType,
ValueTypeWithConstraint : Foo,
AnotherValueTypeWithGenericConstraint: Bar<Baz>, ... > ...
```
The lightweight generic specifier list appears before the base
class, if present, but because it starts with < like the protocol
specifier list, `UnwrappedLineParser` was getting confused and
failed to parse interfaces with both generics and protocol lists:
```
@interface Foo <KeyType> : NSObject <NSCopying>
```
Since the parsed line would be incomplete, the format result
would be very confused (e.g., https://bugs.llvm.org/show_bug.cgi?id=24381).
This fixes the issue by explicitly parsing the ObjC lightweight
generic conformance list, so the line is fully parsed.

This caused us to incorrectly indent 0-argument wrapped selectors
when Style.IndentWrappedFunctionNames was false, as we thought
the 0-argument ObjC selector name was actually a trailing
annotation (which is always indented).
This diff fixes the issue and adds tests.
Test Plan: New tests added. Confirmed tests failed before diff.
After diff, tests passed. Ran tests with:
% make -j12 FormatTests &&
./tools/clang/unittests/Format/FormatTests
