Summary:
Static analysis is very sensitive to environment.
OS and libraries installed can affect the results.  This fact makes
it extremely hard to have a regression testing system that will
produce stable results.

For this very reason, this commit introduces a new dockerized testing
environment, so that every analyzer developer can check their changes
against previous analysis results.

Re-commit D81925 with a bugfix D82370.

Differential Revision: https://reviews.llvm.org/D81925
Differential Revision: https://reviews.llvm.org/D82370

This reverts commit f570d581.

The test was failing on MacOS if you set
LLVM_DEFAULT_TARGET_TRIPLE. For example if you set it to
"x86_64-apple-darwin" clang actually uses
"x86_64-apple-darwin<version>".

To fix this get default triple from clang itself during the
test instead of substituting it in via lit.

Add constant folding for the `shape.rank` operation of the shape dialect.

Differential Revision: https://reviews.llvm.org/D82076

Summary:
When evaluating an expression referencing a constexpr static member variable, an
error is issued because the PDB does not specify a symbol with an address that
can be relocated against.

Rather than attempt to resolve the variable's value within the IR execution, the
values of all constants can be looked up and incorporated into the AST of the
record type as a literal, mirroring the original compiler AST.

This change applies to DIA and native PDB loaders.

This patch enables the following macros when their corresponding
target attributes are set:
      __ARM_FEATURE_SVE (+sve)
      __ARM_FEATURE_SVE2 (+sve2)
      __ARM_FEATURE_SVE2_AES (+sve2-aes)
      __ARM_FEATURE_SVE2_BITPERM (+sve2-bitperm)
      __ARM_FEATURE_SVE2_SHA3 (+sve2-sha3)
      __ARM_FEATURE_SVE2_SM4 (+sve2-sm4)

This implies that the base SVE and SVE2 ACLE (00bet2) are now feature
complete, meaning that all intrinsics are implemented in LLVM and Clang.

Disclaimer:

To implement the ACLE we have had to fix up many parts of LLVM to make it
support scalable vectors. We have also used many target-specific intrinsics
to reduce reliance on parts of LLVM where we know scalable vectors may
not yet be handled properly (e.g. some transformation might drop the
'scalable' flag on a vector type). While we've done a best effort with
the limited testing that is available to us, we're still working to improve the
stability of the implementation. Additionally, Clang may print warnings
that code may have miscompiled. We find this often to be a false alarm
where the wrong interfaces have been used in LLVM and where resulting
code is not actually incorrect. However, this warrants a bug report
and investigation. If you find any bugs or issues, please raise them on
bugs.llvm.org and let us know!

This patch fixes a compiler crash that was hit when trying to simplify
the following code:

getelementptr [2 x i64], [2 x i64]* null, i64 0, <vscale x 2 x i64> zeroinitializer

For the case where we have a null pointer value like above, we just
need to ensure we don't assume the indices are always fixed width.

Previously we just updated a map and moved on. But it possible
we cached known bits information with the vreg that can be used by
another basic block. If the other basic block has a different view
of the VT these known bits won't make sense.

By emitting a copy we ensure we have different vregs before and
after the bitcast. This prevents the known bits from being used
with the wrong type.

Update the rest of lldb to use std::make_unique<>. I used clang-tidy to
automate this, which probably missed cases that are wrapped in ifdefs.

This patch introduces conversion patterns for `spv.module` and `spv._module_end`.
SPIR-V module is converted into `ModuleOp`. This will play a role of enclosing
scope to LLVM ops. At the moment, SPIR-V module attributes (such as memory model,
etc) are ignored.

Some sequences of optimizations can generate call sites which may never be
executed during runtime, and through constant propagation result in dynamic
allocas being converted to static allocas with very large allocation amounts.

The inliner tries to move these to the caller's entry block, resulting in the
stack limits being reached/bypassed. Avoid inlining functions if this would
result.

The threshold of 64k currently doesn't get triggered on the test suite with an
-Os LTO build on arm64, care should be taken in changing this in future to avoid
needlessly pessimising inlining behaviour.

This revision adds a new support header, InterfaceSupport, to contain various generic bits of functionality for implementing "Interfaces". Interfaces embody a mechanism for attaching concept-based polymorphism to a type system. With this refactoring a new InterfaceMap type is added to allow for efficient interface lookups without going through an indirect call. This should provide a decent performance speedup without changing the size of AbstractOperation.

In a future revision, this functionality will also be used to bring Interface like functionality to Attributes and Types.

Again, debugging doesn't work on the new platform without this, so
it's implicitly covered by the testsuite.

This makes "target create /bin/ls" properly detect which platform
is needed when running lldb. Covered by many tests in the suite.

I was holding off on this change until we moved to C++14 as to not have
to convert llvm::make_unique to std::make_unique. That happened a while
ago so here's the first patch for the API which had a bunch of raw
`new`s.
