I have added CHECK lines to the following tests:
llvm/test/CodeGen/AArch64/sve-breakdown-scalable-vectortype.ll
llvm/test/CodeGen/AArch64/sve-calling-convention-tuple-types.ll
llvm/test/CodeGen/AArch64/sve-intrinsics-create-tuple.ll
llvm/test/CodeGen/AArch64/sve-intrinsics-loads.ll
since they are now free of warnings related to invalid use of
EVT::getVectorNumElements() and VectorType::getNumElements().

There was a rogue 'assert' in AArch64ISelLowering for the tuple.get intrinsics,
that shouldn't really have been there (I suspect this was a remnant from when
we expected the wider vector always to have come from a vector CONCAT).
When I tried to create a more minimal reproducer, I found a bug in
DAGCombiner where it drops the scalable flag when trying to fold:
extract_subv (bitcast X), Index --> bitcast (extract_subv X, Index')
This patch fixes both issues.

The passthrough DiagnosticConsumer is an implementation detail of
ClangDiagnosticManagerAdapter and we can just hide it behind the normal
DiagnosticConsumer interface that ClangDiagnosticManagerAdapter is supposed
to implement.
Move the Thumb2SizeReduce pass to before IfConversion when optimising
for minimal code size.
Running the Thumb2SizeReduction pass before IfConversionallows T1
instructions to propagate to the final output, rather than the
ifConverter modifying T2 instructions and preventing them from being
reduced later.
This change does introduce a regression regarding execution time, so
it's only applied when optimising for size.
Running the LLVM Test Suite with this change produces a geomean
difference of -0.1% for the size..text metric.

Summary:
`include/llvm/Frontend/OpenMP/CMakeLists.txt` creates a new target
called `omp_gen` which builds the generated include file `OMP.h.inc`.
This target must therefore be a dependency of every compilation step
whose transitive #include dependencies contain `OMP.h.inc`, or else
it's possible for builds to fail if Ninja (or make or whatever)
schedules that compilation step before building `OMP.h.inc` at all.
A few of those dependencies are currently missing, which leads to
intermittent build failures, depending on the order that Ninja (or
whatever) happens to schedule its commands. As far as I can see,
compiles in `clang/lib/CodeGen`, `clang/lib/Frontend`, and
`clang/examples` all depend transitivily on `OMP.h.inc` (usually via
`clang/AST/AST.h`), but don't have the formal dependency in the ninja
graph.
Adding `omp_gen` to the dependencies of `clang-tablegen-targets` seems
to be the way to get the missing dependency into the `clang/examples`
subdirectory. This also fixes the other two clang subdirectories, as
far as I can see.

Whilst trying to assemble the following test:
clang/test/CodeGen/aarch64-sve-intrinsics/acle_sve_set2.c
I discovered we were hitting some warnings about possible invalid
calls to getVectorNumElements() in getCopyToPartsVector(). I've
tried to fix these by using ElementCount types where possible and
I've made the assumption that we don't support using a fixed width
vector to copy parts of a scalable vector, and vice versa. Looking
at how the copy is implemented I think that's the right thing for
now.

This patch uses ranges for debug information when a function contains basic block sections rather than using [lowpc, highpc]. This is also the first in a series of patches for debug info and does not contain the support for linker relaxation. That will be done as a follow up patch.

With this, a simple hello world links against libSystem.tbd and the
old ld64.lld linker kind of works again with newer SDKs.
The motivation here is to have an arm64 cross linker that's good
enough to be able to run simple configure link checks on non-mac
systems for generating config.h files. Once -flavor darwinnew can
link arm64, we'll switch to that.
On macOS 11, system libraries which are part of the shared cache
are not present on the filesystem anymore. This causes issues
with build.py, because it fails to link binaries with libSystem
or libc++.
The real issue is that build.py was not passing an SDK to the
compiler. The script accepts an argument for the SDK, but it
is currently unused. This patch just threads the SDK through
to the compile and link steps and this fixes a bunch of Shell
test failures on very recent macOS builds.
On macOS 11 (and other aligned OSs), the shared cache method
lists get an additional optimization which removes one level
of indirection to get to the selector.
This patch supports this new optimization. Both codepaths are
covered byt the existing Objective-C tests.
On macOS 11 (and other aligned Apple OSs), the Objective-C runtime
has a new optimization which saves memory by making the method
lists smaller.
This patch adds support for this new method list encoding (while
also keeping backward compatibility). This is implicitely covered
by some existing Objective-C tests.
Summary:
If amdgpu-flat-work-group-size is not specified in LLVM IR, the backend
uses default value of 1024. For this, minimum waves per EU should be 4.
However, backend is still setting minimum value to 1 instead of calculated
value. This is not observed normally as frontend always provide
amdgpu-flat-work-group-size attribute.

ld64 does this, and references an internal rdar:// number as an explanation. No

This allow lowering to support scf.for and scf.if with results. As right now
spv region operations don't have return value the results are demoted to
Function memory. We create one allocation per result right before the region
and store the yield values in it. Then we can load back the value from
allocation to be able to use the results.
