Description

The tool is informing the user that the user-specified optimization is getting ignored.

Solution

The tool is ignoring the array partition directive because of the automatic optimization applied by the tool.

To perform the automatic optimization the tool applies a global config option which is mentioned below. Preview the config option and if not desired, either reduce the default option or remove it.

config_array_partition
