jgiannuzzi opened a new pull request, #47779: URL: https://github.com/apache/arrow/pull/47779
### Rationale for this change This change enables building Arrow C++ for Windows ARM64 with MSVC when setting `ARROW_SIMD_LEVEL` to `NONE`. This is useful to be able to build Arrow with `vcpkg` and use it as a dependency. Setting `ARROW_SIMD_LEVEL` to `NONE` is done to disable the use of `xsimd`, which does not yet support msvc arm64 intrinsics, and is non-trivial to fix. ### What changes are included in this PR? A patch to the vendored `pcg` library, based on https://github.com/imneme/pcg-cpp/pull/99. The upstream pcg library has not been updated in the past 3 years, so this may never get merged. ### Are these changes tested? Yes, the changes have been tested in https://github.com/microsoft/vcpkg/pull/47750 (the same patch for `vcpkg`, which this change would alleviate) and in https://github.com/jgiannuzzi/ParquetSharp/actions/runs/18354286294 (a full run of the ParquetSharp CI, using this patch to build Arrow with `vcpkg`). ### Are there any user-facing changes? Not really, unless you consider adding the ability to build Arrow on Windows ARM64 user-facing? -- This is an automated message from the Apache Git Service.
