Recommend users use readelf instead of objdump to dump .comment contents.
readelf's output is much easier to read than objdump's as you can see below.
$ readelf --string-dump .comment foo

LLD leaves its name and version number to a ``.comment`` section in an output. If you are in doubt whether you are successfully using LLD or -not, run ``objdump -s -j .comment <output-file>`` and examine the +not, run ``readelf --string-dump .comment <output-file>`` and examine the output. If the string "Linker: LLD" is included in the output, you are using LLD. |
