Premerge CI is currently failing with the following after the update to
clang v22:
```
/home/gha/llvm-project/clang-tools-extra/clangd/benchmarks/IndexBenchmark.cpp:92:1: error: '__COUNTER__' is a C2y extension [-Werror,-Wc2y-extensions]
92 | BENCHMARK(dexQueries);
| ^
```
Some original work was done around this in
df1d786c46, which was then done in
upstream Google benchmark in
d8db2f90b6.
The original work done in the patch implementing this feature doesn't
seem to account for as many cases as the upstream patch does. This patch
reverts the diff in df1d786c46 and applies
the applicable hunks from the upstream patch.
Third-party LLVM dependencies
This directory contains third-party dependencies used in various components of LLVM. Integrating a new third-party dependency generally requires it to be licensed under the Apache-with-LLVM-exception license. For integrating code under other licenses, please follow the process explained in the LLVM Developer Policy.
In particular, due to its non-LLVM license, the Boost.Math third-party dependency can exclusively be used within the libc++ compiled library as discussed in this RFC. Do not use it in other parts of LLVM without prior discussion with the LLVM Board (and update this documentation).
