Michael Ho updated IMPALA-7524:
-------------------------------
Labels: codegen (was: )
> Keep frame pointers for generated code
> --------------------------------------
>
> Key: IMPALA-7524
> URL: https://issues.apache.org/jira/browse/IMPALA-7524
> Project: IMPALA
> Issue Type: Improvement
> Components: Backend
> Affects Versions: Impala 2.13.0, Impala 3.1.0
> Reporter: Lars Volker
> Priority: Major
> Labels: codegen
>
> Generated code does not preserve the frame pointer and thus stack unwinding
> does not work when we crash in generated functions. We should preserve the
> frame pointers to make debugging easier. Kudu's experience and our own in
> IMPALA-4132 suggest that the performance hit will be tolerable (but we still
> should do a proper perf evaluation).
> Here's Kudu's way of preserving the frame pointers:
> [module_builder.cc:294|https://github.com/apache/kudu/blob/eb15beabd2d4d86649a35dcd027e1749cc695866/src/kudu/codegen/module_builder.cc#L294].
> Thanks [~tlipcon] for the suggestion.
