The "user-defined conversion by implicit constructor" codepath is already
handled by `B(int)`; we don't need to test `A(const A&)` a second time
via `DA` (nor the isomorphic case with `DB`).
We don't need `&` anywhere in this test.
Generally, `operator()` should be const; this test needn't be special.
(No functional change in test coverage.)
I noticed two problems with the previous implementation:
* N_ALT_ENTRY symbols weren't being handled correctly -- they should
determine the size of the previous symbol, even though they don't
cause a new section to be created
* The last symbol in a section had its size calculated wrongly;
the first subsection's size was used instead of the last one
I decided to take the opportunity to refactor things as well, mainly to
realize my observation
[here](https://reviews.llvm.org/D98837#inline-931511) that we could
avoid doing a binary search to match symbols with subsections. I think
the resulting code is a bit simpler too.

MLIR test Dialect/Linalg/transform-patterns.mlir tries to check for the
absence of a sequence of instructions with several CHECK-NOT with one of
those directives using a variable defined in another. However CHECK-NOT
are checked independently so that is using a variable defined in a
pattern that should not occur in the input.
This commit removes the dependency between those CHECK-NOT by replacing
occurences of variables by the regex that were used to define them.
Note to reviewers: please pay attention to whether the remaining
reference to l0 is correct. There was a l0 defined in those CHECK-NOT
and one defined before. I'm not sure what was the intent there.

Previously, 34-bit constants were materialized in selectI64Imm(), and we relied
on td pattern matching to instead produce a pli. This becomes problematic as
there is no guarantee that the 34-bit constant will reach the td pattern
selection for pli. It is also possible for other transformations (such as complex
bit permutations) to also produce and utilize the 34-bit constant materialized
through selectI64Imm().
This patch instead produces pli on Power10 directly whenever the constant fits
within 34-bits.

I initially suggested SubsectionMapping, but I thought the discussion
landed on doing `std::vector<SubsectionEntry>`. @alexshap went and did
both, but on hindsight I regret adding 3 more characters to an already
long name, and I think SubsectionEntry is descriptive enough...
This diff also renames `subsectionMap` to `subsecMap` for consistency
with other variable names in the codebase.
Add the subclass, update a few places which check for the intrinsic to use idiomatic dyn_cast, and update the public interface of AssumptionCache to use the new class. A follow up change will do the same for the newer assumption query/bundle mechanisms.
If running in a Windows Container, there is no such directory at all.

it doesn't seem to happen on desktop versions.)
If the directory isn't available with the expected behaviour, mark those
individual tests as unsupported. (The test as a whole is considered to
pass, but the unsupported test is mentioned in a test summary printed on

The current code does not properly handle vector indices unless they are
the first index.
At the moment LangRef gives the impression that the vector index must be
the one and only index (https://llvm.org/docs/LangRef.html#getelementptr-instruction).
But vector indices can appear at any position and according to the
verifier there may be multiple vector indices. If that's the case, the
number of elements must match.
This patch updates SimplifyGEPInst to properly handle those additional
cases.

The major change here is to index macro occurrences in more places than
before, specifically
* In non-expansion references such as `#if`, `#ifdef`, etc.
* When the macro is a reference to a builtin macro such as __LINE__.
* When using the preprocessor state instead of callbacks, we now include
all definition locations and undefinitions instead of just the latest
one (which may also have had the wrong location previously).
* When indexing an existing module file (.pcm), we now include module
macros, and we no longer report unrelated preprocessor macros during
indexing the module, which could have caused duplication.
Additionally, we now correctly obey the system symbol filter for macros,
so by default in system headers only definition/undefinition occurrences
are reported, but it can be configured to report references as well if
desired.
Extends FileIndexRecord to support occurrences of macros. Since the
design of this type is to keep a single list of entities organized by
source location, we incorporate macros into the existing DeclOccurrence
struct.

Commit 22ce5eb051, changed checks in
GVN/big-endian.ll into CHECK-NOT. The intent was to check that a
succession of lines does not occur but each CHECK-NOT is checked
independently. In other word, one CHECK-NOT uses a variable defined
in a pattern (the one defining the variable) that should not occur in
the input. The bug was then copied over in NewGVN/big-endian.ll.
This commit only checks for the absence of i16 load which rules out the
presence of the whole sequence and does not involve an undefined
variable.

Previously it wasn't possible to configure a standalone compiler-rt
build if the `LLVMConfig.cmake` file isn't present in a shipped
toolchain.
This patch adds a fallback behaviour for when `LLVMConfig.cmake` is not
available in the toolchain being used for configure. The fallback
behaviour mocks out the bare minimum required to make a configure
succeed when the host is Darwin. Support for other platforms could
be added in future patches.
The new code path is taken either in one of the following cases:
* `llvm-config` is not available.
* `llvm-config` is available but it provides an invalid path for the CMake files.
The motivation here is to be able to generate the compiler-rt lit test
suites for an arbitrary LLVM toolchain and then run the tests against
it.
The invocation to do this looks something like.
```
CC=/path/to/cc \
CXX=/path/to/c++ \
cmake \
-G Ninja \
-DLLVM_CONFIG_PATH=/path/to/llvm-config \
-DCOMPILER_RT_INCLUDE_TESTS=ON \
/path/to/llvm-project/compiler-rt
# Note we don't compile compiler-rt in this workflow.
bin/llvm-lit -v test/path/to/generated/test_suite
```
A possible alternative approach is to configure the
`cmake/modules/LLVMConfig.cmake.in` file in the LLVM source tree
and then include it. This approach was not taken because it is more
complicated.
An interesting side benefit of this patch is that it is now
possible to configure on Darwin without `llvm-config` being available
by configuring with `-DLLVM_CONFIG_PATH=""`. This moves us a step
closer to a world where no LLVM build artefacts are required to
build compiler-rt.

layout.
When doing a standalone compiler-rt build we currently rely on
getting information from the `llvm-config` binary. Previously
we would rely on calling `llvm-config --src-root` to find the
LLVM sources. Unfortunately the returned path could easily be wrong
if the sources were built on another machine.
Now that compiler-rt is part of a monorepo we can easily fix this
problem by finding the LLVM source tree next to `compiler-rt` in
the monorepo. We do this regardless of whether or not the `llvm-config`
binary is available which moves us one step closer to not requiring
`llvm-config` to be available.
To try avoid anyone breaking anyone who relies on the current behavior,
if the path assuming the monorepo layout doesn't exist we invoke
`llvm-config --src-root` to get the path. A deprecation warning is
emitted if this path is taken because we should remove this path
in the future given that other runtimes already assume the monorepo
layout.
We also now emit a warning if `LLVM_MAIN_SRC_DIR` does not exist.
The intention is that this should be a hard error in future but
to avoid breaking existing users we'll keep this as a warning
for now.
