There were some discussions:

Basically with comdat section group, we may have multiple sections with
the same name. It is meaningless to use the section name to identify
the section when reporting error. Users can't tell which section the
linker is having problem. The unique section identifier uses the
section and group names to identify the section so that it is unique.

I will write one in x86 assembly since it needs a compiler with comdat
group support.
