Linker merging of comment sections
If input files have any comment sections that are identical, then the linker can merge them.
If input object files have any
sections that are identical, then the linker merges them to produce the smallest
.comment section while retaining all useful information.
The linker associates each input
.comment section with the filename of the
corresponding input object. If it merges identical
.comment sections, then
all the filenames that contain the common section are listed before the section contents,
file1.o file2.o .comment section contents.
The linker merges these sections by default. To prevent the merging of identical
.comment sections, use the
.commentsection, then use the
--no_comment_sectionoption to strip this section from the image.
