Module re-optimization

We would like the capability to  optimize a module that was previously optimized with an older ABO version in order to benefit of the new ARCH support granted by the newer ABO versions

after the upgrade from Z15 to Z16

    Hi,

    We have evaluated this idea, however, this is not a trivial task to re-optimize a module that has already been optimized for one ARCH level.

    In order to optimize a module for a specific ARCH level, ABO requires the original COBOL input module that hasn't been passed through ABO yet. Even though the original COBOL load module and the once ABO optimized module are COBOL modules, underneath the covers, they are not the same thing.

    So being able to make it work using a pre-optimized ABO module is not a trivial task and is currently not in our roadmap of improvements. As a result, this idea is being rejected.
