Jacques Nadeau updated DRILL-1925:
----------------------------------
Fix Version/s: Future
> inline static nested Accessor class methods
> -------------------------------------------
>
> Key: DRILL-1925
> URL: https://issues.apache.org/jira/browse/DRILL-1925
> Project: Apache Drill
> Issue Type: Improvement
> Components: Execution - Codegen
> Reporter: Chris Westin
> Fix For: Future
>
>
> Some scalar replacement opportunities had to be disabled because the holders'
> references are passed in to static methods on nested Accessor classes as out
> parameters (their members are filled in by the static methods). If we could
> inline those static methods (they generally just seem to be 5-10 lines), then
> those holders could be replaced.
> I thought the best option here would be to run something based on
> BasicInterpreter but which would start a new interpreter for nested function
> calls, but which delegates to the containing interpreter to emit the code.
> But I'm not sure how hard this will be to set up -- it will require mapping
> through the transformations made to locals. And the interpreter calls are
> very broad, covering many instructions each.
