7.40 .ident

This directive is used by some assemblers to place tags in object files. The behavior of this directive varies depending on the target. When using the a.out object file format, as simply accepts the directive for source-file compatibility with existing assemblers, but does not emit anything for it. When using COFF, comments are emitted to the .comment or .rdata section, depending on the target. When using ELF, comments are emitted to the .comment section.
