I cant just agree here, because they contain exactly what I wanted to see, but I should admit I might have misunderstood the
intention of map file. So it can be true. Let me think about it. Thank you for explanation.

The map file is to show how input sections are mapped to some contiguous output memory address, and it's not suitable to print out the information as to how mergeable section pieces are mapped to an output section.
