Re: How to merge multiple compilation units into a compilation unit.

Dear J-P. Rosen
Thank you for giving me valuable advices.

Perhaps "merge" is vague. I want to create a new compilation unit that acts as same as the original two compilation units, so that I can use the new compilation unit to replace the original two compilation units. When a target program is small-scaled, I can create the new compilation unit manually, however, for a large target program that has massive compilation units, the manual process is impossible. Does there exist a tool that implements this function automatically.

AdaControl is great. I installed and used it. From the view of manual reference of AdaControl, ptree is process compilation units one by one?
Thank you very much.
