The D147408 <https://reviews.llvm.org/D147408> implemented new Iterative approach for scan computations
and  added new flag `amdgpu-atomic-optimizer-strategy` which is
defaulted to DPP.

      

The changeset https://github.com/GPUOpen-Drivers/llpc/pull/2506
adapts to the new changes in LLPC.

      

This patch enables atomic optimizer pass and selects Iterative
approach for scan computations by default for compute pipeline.
