Jan Korous 2d000e395e [clangd][xpc][cmake] Respect explicit value of CLANGD_BUILD_XPC
We shouldn't prevent user from disabling XPC framework build on Darwin.
However, by keeping it on by default our CI systems also test
it by default on macOS.

Ilya Biryukov ec5dbf5a7b [clangd] Add .cu files to VSCode extension
Summary:
clangd should be able to handle those with a proper compilation
database. However, users using 'nvcc' might start seeing spurious errors
in '.cu' files after this change.

My plan is to land and release this, but be ready to revert in
case of negative user feedback.

Unfortunately, tooling::createExecutorFromCommandLineArgs doesn't
corperate well with our internal infrastructure, which leads failing
lit tests. We use ClangTool at the moment, until we find a better

Roman Lebedev 462446fd9a [clang-tidy] openmp-exception-escape - a new check
Summary:
Finally, we are here!

Analyzes OpenMP Structured Blocks and checks that no exception escapes
out of the Structured Block it was thrown in.

As per the OpenMP specification, structured block is an executable statement,
possibly compound, with a single entry at the top and a single exit at the
bottom. Which means, ``throw`` may not be used to to 'exit' out of the
structured block. If an exception is not caught in the same structured block
it was thrown in, the behaviour is undefined / implementation defined,
the program will likely terminate.

Roman Lebedev cbbf92825f [clang-tidy] openmp-use-default-none - a new check
Summary:
Finds OpenMP directives that are allowed to contain `default` clause,
but either don't specify it, or the clause is specified but with the kind
other than `none`, and suggests to use `default(none)` clause.

Using `default(none)` clause changes the default variable visibility from
being implicitly determined, and thus forces developer to be explicit about the
desired data scoping for each variable.

Stephane Moore 5f70c473c9 [clang-tidy] Disable google-runtime-int in Objective-C++ 🔓
Summary:
In contrast to Google C++, Objective-C often uses built-in integer types
other than `int`. In fact, the Objective-C runtime itself defines the
types NSInteger¹ and NSUInteger² which are variant types depending on
the target architecture. The Objective-C style guide indicates that
usage of system types with variant sizes is appropriate when handling
values provided by system interfaces³. Objective-C++ is commonly the
result of conversion from Objective-C to Objective-C++ for the purpose
of integrating C++ functionality. The opposite of Objective-C++ being
used to expose Objective-C functionality to C++ is less common,
potentially because Objective-C has a signficantly more uneven presence
on different platforms compared to C++. This generally predisposes
Objective-C++ to commonly being more Objective-C than C++. Forcing
Objective-C++ developers to perform conversions between variant system types
and fixed size integer types depending on target architecture when
Objective-C++ commonly uses variant system types from Objective-C is
likely to lead to more bugs and overhead than benefit. For that reason,
this change proposes to disable google-runtime-int in Objective-C++.

[2] https://developer.apple.com/documentation/objectivec/nsuinteger?language=objc
[3] "Types long, NSInteger, NSUInteger, and CGFloat vary in size between
32- and 64-bit builds. Use of these types is appropriate when handling
values exposed by system interfaces, but they should be avoided for most
other computations."

Ilya Biryukov 373bee85c2 [clangd] Tune the fuzzy-matching algorithm
Summary:
To reduce the gap between prefix and initialism matches.

The motivation is producing better scoring in one particular example,
but the change does not seem to cause large regressions in other cases.

The examples is matching 'up' against 'unique_ptr' and 'upper_bound'.
Before the change, we had:
  - "[u]nique_[p]tr" with a score of 0.3,
  - "[up]per_bound" with a score of 1.0.

A 3x difference meant that symbol quality signals were almost always ignored
and 'upper_bound' was always ranked higher.

However, intuitively, the match scores should be very close for the two.

After the change we have the following scores:
- "[u]nique_[p]tr" with a score of 0.75,
- "[up]per_bound" with a score of 1.0.

Summary:
Using suffix path mapping relies on the STL implementations, and it is

To generate the symbol mapping, we parse the cppreference symbol index
page to build a lookup table.

The mapping is not completed, a few TODOs:
  - support symbols from different headers (e.g. std::move)
  - support STL macros
  - support symbols from std's sub-namespaces (e.g. chrono)
