In the process of running this check on a large codebase I found a
number of limitations, and thought I would pass on my fixes for
possible integration upstream:
* Templated function call operators are not supported
* Function object constructors are always used directly in the lambda
body, even if their arguments are not captured
* Placeholders with namespace qualifiers (std::placeholders::_1) are
not detected
* Lambda arguments should be forwarded to the stored function
* Data members from other classes still get captured with this
* Expressions (as opposed to variables) inside std::ref are not captured
properly
* Function object templates sometimes have their template arguments
replaced with concrete types
This patch resolves all those issues and adds suitable unit tests.
Summary:
NOTE: There is a mailing list discussion on this: http://lists.llvm.org/pipermail/llvm-dev/2019-December/137632.html
Complemantary to the assumption outliner prototype in D71692, this patch
shows how we could simplify the code emitted for an alignemnt
assumption. The generated code is smaller, less fragile, and it makes it
easier to recognize the additional use as a "assumption use".
As mentioned in D71692 and on the mailing list, we could adopt this
scheme, and similar schemes for other patterns, without adopting the
assumption outlining.

Another possible difference between various users of the

Summary:
Docker on its own has a pretty convenient way to run shell.
This method, however, requires target container to be currently running,
which is not a usual scenario for the test system. For this purpose,
it is better to have a simple way to run the container, shell it, and
clean up at the end of it all. New option `--shell` does exactly this.

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

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 f570d58104.
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.
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!

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.
