srielau opened a new pull request, #58410: URL: https://github.com/apache/spark/pull/58410
### What changes were proposed in this pull request? Add a native `common/libbid` module containing pure-Java IEEE 754 BID decimal64 and decimal128 arithmetic together with the binary128 kernels used by transcendental operations. The module is wired into the Maven, SBT, and change-detection builds. It includes the Intel RDFP vector tests and the required BSD 3-Clause license and notice attribution. Standalone publishing metadata and non-ASF copyright references are not included. ### Why are the changes needed? Spark needs an in-tree Java BID implementation as the foundation for libbid-backed decimal support without requiring native code or an unpublished external artifact. ### Does this PR introduce _any_ user-facing change? No. This adds the supporting module but does not yet connect it to a user-facing Spark API or execution path. ### How was this patch tested? - `JAVA_HOME=/usr/lib/jvm/java-17-openjdk-amd64 build/sbt -Dsbt.override.build.repos=true 'libbid/test'` (88 tests passed) - `JAVA_HOME=/usr/lib/jvm/java-17-openjdk-amd64 DEFAULT_ARTIFACT_REPOSITORY=https://maven-proxy.dev.databricks.com/ dev/check-license` - `git diff --check` ### Was this patch authored or co-authored using generative AI tooling?
