### Description The Spark `regexp_instr` function is not offloaded by the Velox backend today, so queries using it fall back to vanilla Spark. Velox already registers the sparksql `regexp_instr(string, pattern)` function with Spark-compatible semantics (1-based char position of the first match, 0 if no match), so this only needs wiring on the Gluten side. **Note:** Spark's `RegExpInStr` exists since 3.4 and carries a third `idx` child, but evaluation ignores it (always returns the start of the whole match). Velox's `regexp_instr` is 2-arg, so the `idx` child should be dropped. ### Gluten version main branch -- This is an automated message from the Apache Git Service.
