Summary:
Currently clang-format would always emit a replacement for a block of Java imports even if it is correctly formatted:
```

% clang-format /tmp/Aggregator.java
import X;
% clang-format -output-replacements-xml /tmp/Aggregator.java
<?xml version='1.0'?>
<replacements xml:space='preserve' incomplete_format='false'>
<replacement offset='0' length='9'>import X;</replacement>
</replacements>
%
```
This change makes clang-format not emit replacements in this case. Note that
there is logic to not emit replacements in this case for C++.

Michael Kruse 4304e9d143 [OpenMP 5.0] Parsing/sema support for map clause with mapper modifier.
This patch implements the parsing and sema support for OpenMP map
clauses with potential user-defined mapper attached. User defined mapper
is a new feature in OpenMP 5.0. A map clause can have an explicit or
implicit associated mapper, which instructs the compiler to generate
extra data mapping. An example is shown below:

    struct S { int len; int *d; };
    #pragma omp declare mapper(id: struct S s) map(s, s.d[0:s.len])
    struct S ss;
    #pragma omp target map(mapper(id) tofrom: ss) // use the mapper with name 'id' to map ss

Alexey Bader 24fa0c18e6 [OpenCL] Change type of block pointer for OpenCL
Summary:

For some reason OpenCL blocks in LLVM IR are represented as function pointers.
These pointers do not point to any real function and never get called. Actually
they point to some structure, which in turn contains pointer to the real block
invoke function.
This patch changes represntation of OpenCL blocks in LLVM IR from function
pointers to pointers to `%struct.__block_literal_generic`.
Such representation allows to avoid unnecessary bitcasts and simplifies
further processing (e.g. translation to SPIR-V ) of the module for targets
which do not support function pointers.

Gabor Marton fc03fc6e69 [ASTImporter] Unify redecl chain tests as type parameterized tests
Summary:
This patch unifies all those tests which check the correctness of the
redecl chains. Previously we had several structurally very similar test
cases for each language construct (class, function, variable, function
template, ...).

We still use value-parameterized tests for the different AST
compatibility switches (-fdelayed-template-parsing, -fms-compatibility).
Gtest makes it possible to have either value-parameterized or
type-parameterized fixtures. However, we cannot have both value- and
type-parameterized test fixtures. So we use a value-parameterized test
fixture in the gtest sense. We intend to mimic gtest's type-parameters
via the type template parameter. We manually instantiate the different
tests with the each types.

After this patch I am planning to put the "generic redecl chain" related
tests into their own separate test file (in another patch).

Volodymyr Sapsai bcb4f7208d [ObjC generics] Fix applying `__kindof` to the type parameter.
Fixes the warning about incompatible pointer types on assigning to a
subclass of type argument an expression of type `__kindof TypeParam`.

We already have a mechanism in `ASTContext::canAssignObjCInterfaces`
that handles `ObjCObjectType` with `__kindof`. But it wasn't triggered
because during type substitution `__kindof TypeParam` was represented as
`AttributedType` with attribute `ObjCKindOf` and equivalent type
`TypeArg`. For assignment type checking we use canonical types so
attributed type was desugared and the attribute was ignored.

The fix is in checking transformed `AttributedType` and pushing
`__kindof` down into `ObjCObjectType` when necessary.

Richard Smith afcfb6bc3a Fix implementation of [temp.local]p4.
When a template-name is looked up, we need to give injected-class-name
declarations of class templates special treatment, as they denote a
template rather than a type.

Previously we achieved this by applying a filter to the lookup results
after completing name lookup, but that is incorrect in various ways, not
least of which is that it lost all information about access and how
members were named, and the filtering caused us to generally lose
all ambiguity errors between templates and non-templates.

We now preserve the lookup results exactly, and the few places that need
to map from a declaration found by name lookup into a declaration of a
template do so explicitly. Deduplication of repeated lookup results of
the same injected-class-name declaration is done by name lookup instead
of after the fact.

This reinstates r354091, which was previously reverted in r354097
because it exposed bugs in lldb and compiler-rt. Those bugs were fixed
in r354173 and r354174 respectively.

Reid Kleckner c1648f2bfd [MSVC] Recognize `static_assert` keyword in C and C++98
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.

  Address Loc =

Already adjusts Loc from thr alloca to a GEP. This code:

    if (emission.IsEscapingByRef)

Was trying to do the same adjustment, and a GEP on a GEP (returning an int) triggers an assertion.

Similar to code expanded from macros.

This means the warning no longer fires on this code:
  for (auto C : collection) {
    process(C);
    return;
  }
  handleEmptyCollection();
Unclear whether this is more often a bug or not in practice, I think it's a
reasonable idiom in some cases.
Either way, if we want to warn on "loop that doesn't loop", I think it should be
a separate warning, and catch `while(1) break;`

Richard Smith a6e8d5e554 PR40642: Fix determination of whether the final statement of a statement
expression is a discarded-value expression.

Summary:
We used to get this wrong in three ways:

1) During parsing, an expression-statement followed by the }) ending a
   statement expression was always treated as producing the value of the
   statement expression. That's wrong for ({ if (1) expr; })
2) During template instantiation, various kinds of statement (most
   statements not appearing directly in a compound-statement) were not
   treated as discarded-value expressions, resulting in missing volatile
   loads (etc).
3) In all contexts, an expression-statement with attributes was not
   treated as producing the value of the statement expression, eg
   ({ [[attr]] expr; }).

Also fix incorrect enforcement of OpenMP rule that directives can "only
be placed in the program at a position where ignoring or deleting the
directive would result in a program with correct syntax". In particular,
a label (be it goto, case, or default) should not affect whether
directives are permitted.

Bruno Ricci c39f8dfa73 [Sema] Fix a regression introduced in "[AST][Sema] Remove CallExpr::setNumArgs"
D54902 removed CallExpr::setNumArgs in preparation of tail-allocating the
arguments of CallExpr. It did this by allocating storage for
max(number of arguments, number of parameters in the prototype). The
temporarily nulled arguments however causes issues in BuildResolvedCallExpr
when typo correction is done just after the creation of the call expression.

This was unfortunately missed by the tests /:

To fix this, delay setting the number of arguments to
max(number of arguments, number of parameters in the prototype) until we are
ready for it. It would be nice to have this encapsulated in CallExpr but this
is the best I can come up with under the constraint that we cannot add
anything the CallExpr.

consider only those which have the same visibility as the decl we

We consider two decls in two anonymous namsepaces to have the same

__hipRegisterFunction and __hipRegisterVar need to accept device side kernel and variable names
so that HIP runtime can associate kernel stub functions in host code with kernel symbols in fat binaries,
and associate shadow variables in host code with device variables in fat binaries.

Currently, clang assumes kernel functions and device variables have the same name as the kernel
stub functions and shadow variables. However, when host is compiled in windows with MSVC C++
ABI and device is compiled with Itanium C++ ABI (e.g. AMDGPU), kernels and device symbols in fat
binary are mangled differently than host.

Aaron Enye Shi 7084b56ee2 [HIP] Handle compile -m options and propagate into LLC
Allow the compile options for -m such as -mxnack/-mno-xnack, -msram-ecc/-mno-sram-ecc, -mcode-object-v3/-mno-code-object-v3 to propagate into LLC args. Fix an issue where -mattr was pushed even when it was empty.

Also add lit tests to verify features are properly passed.

Adam Balogh 3bd63ae381 [Analyzer] Crash fix for FindLastStoreBRVisitor
FindLastStoreBRVisitor tries to find the first node in the exploded graph where
the current value was assigned to a region. This node is called the "store
site". It is identified by a pair of Pred and Succ nodes where Succ already has
the binding for the value while Pred does not have it. However the visitor
mistakenly identifies a node pair as the store site where the value is a
`LazyCompoundVal` and `Pred` does not have a store yet but `Succ` has it. In
this case the `LazyCompoundVal` is different in the `Pred` node because it also
contains the store which is different in the two nodes. This error may lead to
crashes (a declaration is cast to a parameter declaration without check) or
misleading bug path notes.

In this patch we fix this problem by checking for unequal `LazyCompoundVals`: if
their region is equal, and their store is the same as the store of their nodes
we consider them as equal when looking for the "store site". This is an
approximation because we do not check for differences of the subvalues
(structure members or array elements) in the stores.

Erik Pilkington e3cd735ea6 Add a new attribute, fortify_stdlib
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
defaults.

In GCC, this is done by adding gnu_inline-style wrapper functions,
but that doesn't work for us for variadic functions because we don't
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.

Eli Friedman 88fccbdea7 [Sema] Mark GNU compound literal array init as an rvalue.
Basically the same issue as string init, except it didn't really have
any visible consequences before I removed the implicit lvalue-to-rvalue
conversion from CodeGen.

While I'm here, a couple minor drive-by cleanups: IgnoreParens never
returns a ConstantExpr, and there was a potential crash with string init
involving a ChooseExpr.

The analyzer test change maybe indicates we could simplify the analyzer
code a little with this fix?  Apparently a hack was added to support
lvalues in initializers in r315750, but I'm not really familiar with the
relevant code.

Heejin Ahn 9d5a089bf5 [WebAssembly] Make thread-related options consistent
Summary:
There have been three options related to threads and users had to set
all three of them separately to get the correct compilation results.
This makes sure the relationship between the options makes sense and
sets necessary options for users if only part of the necessary options
are specified. This does:

- Remove `-matomics`; this option alone does not enable anything, so
  removed it to not confuse users.
- `-mthread-model posix` sets `-target-feature +atomics`
- `-pthread` sets both `-target-feature +atomics` and
  `-mthread-model posix`
Also errors out when explicitly given options don't match, such as
`-pthread` is given with `-mthread-model single`.
