> Key: HARMONY-3853
> URL: https://issues.apache.org/jira/browse/HARMONY-3853
> Project: Harmony
> Issue Type: Bug
> Components: Website/Documentation
> Reporter: George Timoshenko
> Assigned To: Nadya Morozova
> Priority: Minor
>
> In this doc:
> http://harmony.apache.org/subcomponents/drlvm/JIT.html#HIR_Optimizations
> The following text:
> Lowering (lower) performs basic instruction-level transformations to replace common helper calls with the corresponding HIR code. A helper call generally is performance-expensive, so that inlining the operation performed by a helper method can improve performance. This is especially true for operations that are proved to be redundant afterwards.

> is repeated twice as "Scope Enhancement" and "Redundancy Elimination" pass.
> As far as I understand only "Scope Enhancement" should be kept.
