The current docs for the .ident pseudo-op read: @cindex @code{ident} directive This directive is used by some assemblers to place tags in object files. @command{@value{AS}} simply accepts the directive for source-file compatibility with such assemblers, but does not actually emit anything for it. But, at least for x86 Linux, .ident does emit the tag in a .comment section.
