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 c=
ompilation unit to replace the original two compilation units. When a targe=
t 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 refer=
ence of AdaControl, ptree is process compilation units one by one?
Thank you very much.
