It fails with -DENABLE_EXPERIMENTAL_NEW_PASS_MANAGER=0 builds. Temporarily use -fno-experimental-new-pass-manager while we are investigating the root cause.
Summary:
This instruction is not merged to the spec proposal, but we need it to
be implemented in the toolchain to experiment with it. It is available
only on an opt-in basis through a clang builtin.

Summary:
Adds a constructor that takes a vector with which to initialize the `Parts`
field and a corresponding free function that forwards to the constructor. These
definitions are needed to assist in transitioning away from `Stencil` as a class
to defining it as a type alias.

Support for C++ mode was accidentally lacking due to not checking the
OpenCLCPlusPlus LangOpts version.
Differential Revision: https://reviews.llvm.org/D69233
Summary:
Introduces a clang builtins and LLVM intrinsics representing integer
min/max instructions. These instructions have not been merged to the
SIMD spec proposal yet, so they are currently opt-in only via builtins
and not produced by general pattern matching. If these instructions
are accepted into the spec proposal the builtins and intrinsics will
be replaced with normal pattern matching.

When a target does not support pragma detect_mismatch, an llvm.linker.options
metadata with an empty entry is created, which causes diagnostic in backend
since backend expects name/value pair in llvm.linker.options entries.
This patch fixes that.

Add support for continuously syncing profile counter updates to a file.
The motivation for this is that programs do not always exit cleanly. On
iOS, for example, programs are usually killed via a signal from the OS.
Running atexit() handlers after catching a signal is unreliable, so some
method for progressively writing out profile data is necessary.
The approach taken here is to mmap() the `__llvm_prf_cnts` section onto
a raw profile. To do this, the linker must page-align the counter and
data sections, and the runtime must ensure that counters are mapped to a
page-aligned offset within a raw profile.
Continuous mode is (for the moment) incompatible with the online merging
mode. This limitation is lifted in https://reviews.llvm.org/D69586.
Continuous mode is also (for the moment) incompatible with value
profiling, as I'm not sure whether there is interest in this and the
implementation may be tricky.
As I have not been able to test extensively on non-Darwin platforms,
only Darwin support is included for the moment. However, continuous mode
may "just work" without modification on Linux and some UNIX-likes. AIUI
the default value for the GNU linker's `--section-alignment` flag is set
to the page size on many systems. This appears to be true for LLD as
well, as its `no_nmagic` option is on by default. Continuous mode will
not "just work" on Fuchsia or Windows, as it's not possible to mmap() a
section on these platforms. There is a proposal to add a layer of
indirection to the profile instrumentation to support these platforms.

Previously, given a CompilationDatabase with two commands for the same
source file we would report that file twice with the union of the
dependencies for each command both times.
This was due to the way `ClangTool` runs actions given an input source
file (see the comment in `DependencyScanningTool.cpp`). This commit adds
a `SingleCommandCompilationDatabase` that is created with each
`CompileCommand` in the original CDB, which is then used for each
`ClangTool` invocation. This gives us a single run of
`DependencyScanningAction` per `CompileCommand`.
I looked at using `AllTUsToolExecutor` which is a parallel tool
executor, but I'm not sure it's suitable for `clang-scan-deps` as it
does a lot more sharing of state than `AllTUsToolExecutor` expects.

I built locally with the latest MSVC in c++14 and c++17, but it does not
complain for me. Osman Zakir on llvm-dev reports that they run into
compile errors here.
In any case, it seems prefereable to reuse clang's LLVM.h header to
bring in llvm::Optional and Expected.
Summary:
This fixes an edge case in the `SpacesInSquareBrackets` option where an initial `&ref` lambda parameter is not padded with an initial space.
`int foo = [&bar ]() {}` is fixed to give `int foo = [ &bar ]() {}`

Recognization of function names is done now with the CallDescription

This adds a flag to LLVM and clang to always generate a .debug_frame

from a compilation database. The output format is experimental and will change.
It is currently a concatenation of JSON outputs for each compilation. Future

When throwing objects with deleted copy constructors, the copy ctor
field of the catchable type should remain null and the mangle name
changes. This already worked in simple cases, but in cases involving
non-trivial subobjects, sometimes LookupCopyingConstructor could return
a non-null but deleted constructor decl. Skip those and don't reference
them.

We previously failed the entire condition evaluation if an unmodeled

unused in the attribute's condition.
D63607 made mac builders unhappy by failing this test, and it isn't

Removed the explicit list of supported features from OpenMP 5.0 and used
the reference to the table instead. Also, fixed info about constructs
that can be executed in SPMD mode, if and num_threads clauses do not
affect it anymore.
Summary:
That decl kind is currently not implemented. BuiltinTemplateDecl is for decls that are hardcoded in the
ASTContext, so we can import them like we do other builtin decls by just taking the equivalent
decl from the target ASTContext.

On Windows and macOS, the filesystem is case insensitive, and these files
interfere with each other. Reading through, the case of the file extension
is part of the test. I've altered the rest of the name instead.
This patch adds a new Flang mode. When in Flang mode, the driver will
invoke flang for fortran inputs instead of falling back to the GCC
toolchain as it would otherwise do.
The behaviour of other driver modes are left unmodified to preserve
backwards compatibility.
It is intended that a soon to be implemented binary in the flang project
will import libclangDriver and run the clang driver in the new flang
mode.
Please note that since the binary invoked by the driver is under
development, there will no doubt be further tweaks necessary in future
commits.
* Initial support is added for basic driver phases
* -E, -fsyntax-only, -emit-llvm -S, -emit-llvm, -S, (none specified)
* -### tests are added for all of the above
* This is more than is supported by f18 so far, which will emit errors
for those options which are unimplemented.
* A test is added that ensures that clang gives a reasonable error
message if flang is not available in the path (without -###).
* Test that the driver accepts multiple inputs in --driver-mode=flang.
* Test that a combination of C and Fortran inputs run both clang and
flang in --driver-mode=flang.
* clang/test/Driver/fortran.f95 is fixed to use the correct fortran
comment character.

Constexpr data member conversions work by starting with the class that
originally introduced the field, and converting from there to the type
that the user desires. Before this change, Clang was using the
inheritance model from the final destination class type instead of the
model from the class that originally introduced the field. To fix this,
find the relevant FieldDecl and take its parent class instead of using
the member pointer type the user provided.
Indirect field decls require some special handling to find the parent
class.
Fixes PR43803
