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
.comment sections that are identical, then
the linker merges them to produce the smallest
.common 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
Notearmlink does not preprocess comment sections from armclang. If you do not want to retain the information in a
.commentsection, then use the fromelf command with the
--strip=commentoption to strip this section from the image.
